Everybody has several games that mean quite a lot to them. For me, one of these games is Indiana Jones and the Infernal Machine. I not only grew up with this game, but I also have a lot of memories of this game. Outside of that, I also met some amazing friends through the community behind this game. I even did several speedruns of this game, and I’m an active member of the community. Now, color me surprised that 25 years after the release of this game, we got new fan-made content for this game. Not just fan made content in the style of fan patches to solve bugs with the game, a whole new level and promises of a level editor to create even more new custom content. This blew me off my socks and in today’s article I want to talk about it. So strap in and let’s get ready to play new content for one of the best Indiana Jones games ever made.

The new level – SED

There is a speedrunning discord server for this game. Well, it was a speedrunning discord server but for a few years now, this server has grown into a server of people who appreciate this game. If you want to join this discord, here is an invite link. When the server started to grow, several modders joined our server. One of these modders is going under the name of Urgon (currently) and what we didn’t know is that he was decompiling the whole game. Not only that, he was creating a level editor based upon an existing level editor.

This existing level editor is for Star Wars Jedi Knight & Mysteries of the Sith. Those games used an engine that formed the basis for the Jones3D engine. While he was developing that editor, he tested his skills by creating a new level. So, basically, parts of this new level are tests of the new level editor and what you can do with it.

Now, information about this new level and the download link can be found at this GitHub repository. If you want to download the actual level, you have to go to this page and click the green button named “Code”. In that dropdown, you can choose “download zip”. You’ll need that later if you want to install/play this custom level. Now, if you read the pre-mod or the installation instructions for this level, you might feel overwhelmed if you aren’t very technically inclined. That’s why two community members wrote two special tools to aid you in preparing your game.

You might ask yourself, like Klamath did in at the end of our stream of this custom level, why are there two tools for basically the same? Well, let me tell you the history about it. When I wanted to play the custom level, I had a bit of trouble myself while figuring out the tutorial. I also found that the required steps were quite a lot to do. So, I decided to start writing a PowerShell script that did all the steps. I announced that in the Indy3D discord that I was writing this. When I almost completed my tool, the_Kovic dropped his version of the tool.

Personally, I didn’t want to throw my work out the window and continued finishing my GUI version. When I finished, I didn’t convert my tool to an EXE and left it just as a script file you could run using a command line or a code editor. The next day, Kovic released a GUI version of his tool and I gave some feedback on his tool. In the days after that, I created an EXE version of my tool and we both kept adding features in our tool. He wrote his tool in C#, which is a bit friendlier to create an EXE. If I didn’t release my first version as a script only and converted it to an EXE, I think it might have been less overwhelming for people.

That said, Kovic thanked me for creating my tool since like he said on our stream: “It put my butt into gear to create a tool and write a GUI, which I normally don’t write“. On top of that, our tools aren’t meant to compete with each other. I can’t write C# and Kovic can’t write PowerShell. And it would be a shame to just delete work because somebody else was quicker or made their tool more user-friendly first. The result now is that we both have two very strong tools with a very similar, maybe even completely the same, feature set.

Outside a different choice of coding language, the biggest differences between both our tools are under the hood. In Kovic’s tool, you get more files than in my tool when you download the tool. And that’s because to prepare your game for custom levels, you need to extract several files in the resource folder. The tool used for extraction has a bug where instead of extracting the folders of the archive into the resource folder, it extracts them into separate folders, like if you would extract a zip file. Kovic packs a modified version of this extraction tool so that part of the process goes a bit faster. In my version, the tool just downloads the latest official versions of the tool and prepare the game that way.

In the end, both our tools give you the same end result. They prepare your game to install custom levels and play them. If you want to try out the_kovic’s tool, you can find the latest version on this releases page. If you want to try our my tool, you can find it on this releases page. Feedback to our tools is always welcome! If you find an issue or if you have an idea, feel free to hit us up, and we will look into it.

Earlier I talked about a stream of the level we did. Klamath, the_Kovic and me did a live stream where we played through this level. Now, I have to emphasize that release of this level is an impressive technical achievement. Creating a level for a 3D game isn’t easy and requires a lot of work. It’s even more impressive when you know that not everything is documented about the engine, and you have to decompile a lot of it. In the next part of this article, I’m going to talk about the level itself and critique it.

If you don’t want spoilers, I’d advise you to skip that section for now and come back later. Now, I want to say that I start reviewing the level in a moment, but this feedback is mostly meant for people who want to make new custom content. What did this new level do right and wrong if you look at it as a player who doesn’t know the technical background of this level? This isn’t meant to break down the amazing work the modders did to make this work.

Reviewing the new level

Editorial note: this review will spoil quite a lot. If you don’t want to get spoiled, you have to skip this section of the article. This isn’t a walkthrough of the level either. Some sections are skipped, I’m only going to talk about the sections I want to talk about.

The new level takes place 25 years after the ending of the original game. Indy returns to his Canyonlands dig site. You are set loose at the tent where Sophia picked Indy up with a helicopter to start the Infernal Machine adventure.

In terms of new content, there isn’t a lot new to see. Some ladders are missing and some parts of the level are blocked off. Also, all treasures are missing that you would usually find in the level.

Before I continue, I want to mention that some parts of this level are made quite difficult on purpose. The developer wanted to give us the feeling we were young kids again, playing this game for the first time, and have us figure out the new puzzles by ourselves. Yet, finding a correct balance between difficulty and unfair is a very fine line to thread. Personally, I think that in some sections, the developer crossed the line into unfair level design.

When running on the top section, you notice that there are some new voice lines. These voice lines are made possible with a voice cloning AI tool that was trained on lines from Doug Lee, the original voice actor for this game. The new voice lines sound amazing, and if you didn’t know better, you’d think that Doug Lee came back to record the new lines. In most cases, these voice lines really fit Indy’s personality and fit right into the game.

We come to our first snag when we want to go to the new content. I can understand not seeing the shovel and being confused, since it’s hanging at the jeep on top. And you know what’s even more confusing, the other side of the jeep model has a shovel in its texture! Anyhow, when you pick up the shovel and dig up the Infernal Machine part, it’s clear that you need to break a wall. Here comes one of the worst parts of this level. The location of this cracked wall is insanely well hidden. It’s in one of the last places you’d look, and several of the first players ran around for hours upon hours in Canyonlands before it was found. And when it was found, it made us annoyed.

It’s a clear example of how players who are used to the level, overlooking the obvious. The wall you need to break has an actual cracked wall texture, but it’s behind something you can’t see through. I think it would have been fine if the location, where it is at, had a bigger ledge so you’d notice it somewhat instead of just having to go on a wild goose chase.

Now, we enter the new area. We come to a big open space where the next set of puzzles are. The first puzzle is actually a jumping puzzle. Now, I highly advise you to not play this level if you haven’t played through most of Indiana Jones and the Infernal Machine. Not that there are spoilers, but because some of the jumps in this level are straight up difficult and not what you really expect from this game. Kovic calls it “Kaizo Jones” for a good reason.

There are some small platforms and not having the look key working is going to be a pain in this section. Since, there are some moments where you need to be able to free look and not being able to see beneath or above you will make things a lot more tricky. After you finished these jumps, you might start to notice that the developer of this custom level added some details. Like, the rope bridges are gently moving in the wind. This is something that isn’t present in the original game. It’s a new “COG” script that makes that possible.

These cog scripts are a blessing for custom content. Since, this game isn’t hardcoded at all, so if you learn how to write these cog scripts, you can basically write new mechanics as well. It’s insane what possibilities there are going to be in the future for this game. I hope there is going to be good documentation so that custom level creaters know what’s possible and what’s impossible with the level editor.

While you are exploring this area, you notice that it’s huge. This also explains why it takes quite a while to load this level. Currently, modders are looking into why it’s running so slow. Since, we don’t really know if it’s the level size or something else slowing down the loading of this level.

So, after jumping around the central column, you’ll arive at the shed. Here you notice you can actually enter the shed from the top. Kovic explains it quite well during the stream. If you want to hear some technical explanations on how this level works, I’d advice you to watch our stream. Since there is a lot of interesting development talk in there. Later, Kovic and myself had a contest in trying to quote voice lines from the main game. We got close to 200. Kovic won that because I said a line he already said.

After you picked up everything from this shed and climbed outside, you experience another new mechanic of this game. It’s a mechanic that gets backported from Indiana Jones and the Emperor’s Tomb. The fact you can use your whip to go over a zipline.

After you returned and struggled with getting across the other bridge, you will encounter other parts of this level. Here you’ll encounter two voice lines that straight up lie to you. The first voice line is that you need more force, explosives to break a rock that’s blocking your way forwards. Here is the issue with that, you get an explosive barrel later. You need to find an extremely hidden swim tunnel in the water. It’s not the only hidden thing in the water, so investigate behind and underneath rocks quite well. Since, these puzzles in this water border in the unfair territory. What makes that explosive voice line even more evil is that there is a box of TNT in the shed earlier. But what’s the second voice line that lies to you?

Well, that is after you made your way past said boulder. You find a minecart and interacting with it, Indy says that it will run with gasoline. And there is still gasoline left in the shed. Sadly, you can’t pick it up anymore. Now, this is a red haring, you don’t need this minecart at all.

By now, you have learned that this level likes to break the rules of how the main game is designed. You’ll have to think outside of the box sometimes to beat this level. But, for some jumps, you need to use your knowledge of what’s possible and impossible to progress. This makes it quite tricky sometimes to progress. And this brings me to a conclusion we also said on stream. I think that the issue is that people expected a more tame level than what we actually got and that might turn some people off. But, I’m so glad that the quick save system exists in this game. So, abuse the quick save system and make multiple saves since you’ll need them if you aren’t a veteran player of this game.

Anyhow, let’s get back into the flow of the level. After we completed the lever puzzle, we go back towards to the huge open area and take the lift to a new location. What follows is a totally new area where it’s a good thing if you saved up on health packs and you have a great sense of direction.

So, the short minecart ridge comes to an end. It doesn’t take long before you find yourself into a watermaze. This watermaze is unfair in my honest opinion. Klamath had a tricky time solving it and he had to use almost every health pack to get through it. Without Kovic pointing out the right tunnel, I think it would have made the stream quite a bit longer. There was supposed to be a minecart section instead of this swimming maze, but the developer had a hard time making the minecart section to work and he gave up and made this swimming maze.

Now, I’m all fine with this swimming maze, but the map glitches out at certain parts. I have a mediocre sense of direction and I wanted to rely on the map. The map doesn’t always render the tunnels correctly. You sometimes swim off the map or “in nothingness”. Sadly, I have to draw my own map. I wish I still had it, since it would make for a nice screenshot here… But I threw it out but me and my clumsiness… I knocked over my waterbottle over it.

After the swimming maze, we get a new section of “Kaizo Jones”. Where we get some extremely tricky platforming. Here is where you need to use the look key again and be sure you are playing in 4:3. If you are playing in another resolution like 16:9 or 16:10, this will also be one of the moments where you don’t see all the information.

The block puzzle that follows, feels right out of Tomb Raider. The initial reviews of this game called out this game as a Tomb Raider clone. While, this game does the formula a whole lot differently. We even talked about that during the stream. In terms of theming, Infernal Machine is a lot better. Tomb Raider feels like obstacle courses. But that’s thanks to a different engine and control style. If you want to hear the whole discussion, you can watch the stream from this point. Excuse Kovic’s internet being spotty while he was replying.

After the block puzzle, a new path opens in the swim maze. Then, some platforming comes. Something I love is how there is even a troll hidden inside the platforming. It caught me off guard and made me smile. This platforming section was also love to do. It felt like a real test on how well I know the game. This platforming section feels a lot better put together and feel less cryptic on where you need to go next. You really start to notice that the developer was getting more used to the level editor and made better puzzles. The moment of having to use the whip to swing over the gap while the platform underneath you was breaking was amazing.

After that, we get into the finale of this level. We jump into a portal and we land in a playable area which is shown at the end of Shambala, the 4th level in the original game. That area that’s shown to you after you have beaten the Ice Guardian. The path that takes you to Palawan Lagoon. It was possible to explore that using cheats and modified saves, but now it’s in a level for real. Exploring the little house at the end brings us to something you totally don’t expect this custom level to do. You’ll find a parchment inside with a riddle and at the end you notice something in red saying: “MAT -> ZIP”.

There is some meta gaming now going on. You’ll need to make a hard save and exit your game. You’ll need to go to your resource folder & then open the MAT folder. In there you’ll need to rename “SED.MAT” to “SED.ZIP”. You’ll also need to enter the password for the zip, since you get a new cog script to continue the level, which you need to place in your cog folder. In there, there is another surprise. But, that’s something I’m not going to spoil. But, be sure that Kovic is playing with that surprise and maybe I’m going to dig into it. PS, the next paragraph is in white with the right spelling of the password:

Marcus

The way the level ends is bittersweet. If you solve the final puzzle, something special happens and you can beat the level. You could argue that the ending of this level is “lazy” or “creative”… But, it’s an amazing way to wrap up the story in one level with a nice bow.

At the start of the custom level, I felt that it was quite rough around the edges and it had some moments that felt badly designed. In terms of game design that is. If you look at it visually and level flow wise, I personally think that this level would fit right into the original game as a final challenge. But, the further you go into the level, the more you start to notice that the developer of this level is getting used to the tools and the editor and more polished puzzles and area’s are coming through. You notice the journey of the developer and see it becoming better and better.

I want to give a big congrats to everybody who was involved in releasing this custom level. It’s a blast to play and I can’t wait to see more custom levels. The stream I did with this level was one of the best streams ever and it was also quite a lot of fun to write the tool to help people play this custom level. I’m curious what you think about this custom level and/or the content of this article. Feel free to drop something in the comment section down below.

And with that, I have said everything I wanted to say about this for now. I want to thank you so much for reading and I hope you enjoyed it as much as I enjoyed writing it. I hope to welcome you back in another article but until then, have a great rest of your day and take care.

A technical paper titled “Substrate Embedded Power Electronics Packaging for Silicon Carbide MOSFETs” was published by researchers at University of Cambridge, University of Warwick, Chongqing University, and SpaceX.

Abstract:

“This paper proposes a new power electronic packaging for discrete dies, namely Standard Cell which consists of a step-etched active metal brazed (AMB) substrate and a flexible printed circuit board (flex-PCB). The standard cell exhibits high thermal conductivity, complete electrical insulation, and low stray inductance, thereby enhancing the performance of SiC MOSFET devices. The standard cell has a stray power loop inductance of less than 1 nH and a gate loop inductance of less than 1.5 nH . The standard cell has a flat body with surface-mounting electrical connections on one side and direct thermal connections on the other. The use of flex-PCB die interconnection enables maximum utilization of source pads while providing a flexible gate-source connection and the converter PCB. This paper presents the design concept of the standard cell and experimentally validates its effectiveness in a converter system.”

Want to get middle-school kids excited about science? Let them do their own experiments on MIT.nano’s state-of-the-art microscopes — with guidelines and adult supervision, of course. That was the brainchild of Carl Thrasher and Tao Cai, MIT graduate students who spearheaded the Electron Microscopy Elevating Representation and Growth in Education (EMERGE) program.

Held in November, EMERGE invited 18 eighth-grade students to the pilot event at MIT.nano, an interdisciplinary facility for nanoscale research, to get hands-on experience in microscopy and materials science.

The highlight of the two-hour workshop: Each student explored mystery samples of everyday materials using one of two scanning electron microscopes (SEMs), which scan material samples using a beam of electrons to form an image. Though highly sophisticated, the instruments generated readily understandable data — images of intricate structures in a butterfly wing or a strand of hair, for example.

The students had an immediate, tangible sense of success, says Thrasher, from MIT’s Department of Materials Science and Engineering (DMSE). He led the program along with Cai, also from DMSE, and Collette Gordon, a grad student in the Department of Chemistry.

“This experience helped build a sense of agency and autonomy around this area of science, nurturing budding self-confidence among the students,” Thrasher says. “We didn’t give the students instructions, just empowered them to solve problems. When you don’t tell them the solution, you get really surprised with what they come up with.”

The students were part of a multi-year science and engineering exploration program called MITES Saturdays, run by MIT Introduction to Technology, Engineering, and Science, or MITES. A team of volunteers was on hand to help students follow the guidance set out by Thrasher, ensuring the careful handling of the SEMs — worth roughly $500,000 each.

MITES Saturdays program administrator Lynsey Ford was thrilled to observe the students’ autonomous exploration and enthusiasm.

“Our students got to meet real scientists who listened to them, cared about the questions they were asking, and welcomed them into a world of science,” Ford says. “A supportive learning environment can be just as powerful for science discovery as a half-million-dollar microscope.”

The pilot workshop was the first step for Thrasher and his team in their goal to build EMERGE into a program with broad impact, engaging middle-to-high school students from a variety of communities.

The partnership with MITES Saturdays is crucial for this endeavor, says Thrasher, providing a platform to reach a wider audience. “Seeing students from diverse backgrounds participating in EMERGE reinforces the profound difference science education can have.”

MITES Saturdays students are high-achieving Massachusetts seventh through 12th graders from Boston, MIT’s hometown of Cambridge, and nearby Lawrence.

“The majority of students who participate in our programs would be the first person in their family to go to college. A lot of them are from families balancing some sort of financial hardship, and from populations that are historically underrepresented in STEM,” Ford says.

Experienced SEM users set up the instruments and prepared test samples so students could take turns exploring specimens such as burrs, butterfly wings, computer chips, hair, and pollen by operating the microscope to adjust magnification, focus, and stage location.

Students left the EMERGE event with copies of the electron microscope images they generated. Thrasher hopes they will use these materials in follow-up projects, ideally integrating them into existing school curricula so students can share their experiences.

EMERGE co-director Cai says students were excited with their experimentation, both in being able to access such high-end equipment and in seeing what materials like Velcro look like under an SEM (spoiler alert: it’s spaghetti).

“We definitely saw a spark,” Cai says. “The subject matter was complex, but the students always wanted to know more.” And the after-program feedback was positive, with most saying the experience was fun and challenging. The volunteers noted how engaged the students were with the SEMs and subject matter. One volunteer overheard students say, “I felt like a real scientist!”

Inspiring tomorrow’s scientists

EMERGE is based on the Scanning Electron Microscopy Educators program, a long-running STEM outreach program started in 1991 by the Air Force Research Laboratory and adopted by Michigan State University. As an Air Force captain stationed at Wright-Patterson Air Force Base in Ohio, Thrasher participated in the program as a volunteer SEM expert.

“I thought it was an incredible opportunity for young students and wanted to bring it here to MIT,” he says.

The pilot was made possible thanks to support from the MITES Saturdays team and the Graduate Materials Council (GMC), the DMSE graduate student organization. Cai and DMSE grad student Jessica Dong, who are both GMC outreach chairs, helped fund, organize, and coordinate the event.

The MITES Saturdays students included reflections on their experience with the SEMs in their final presentations at the MITES Fall Symposium in November.

“My favorite part of the semester was using the SEM as it introduced me to microscopy at the level of electrons,” said one student.

“Our students had an incredible time with the EMERGE team. We’re excited about the possibility of future partnerships with MIT.nano and other departments at MIT, giving our scholars exposure to the breadth of opportunities as future scientists,” says Eboney Hearn, MITES executive director.

With the success of the pilot, the EMERGE team is looking to offer more programs to the MITES students in the spring. Anna Osherov is excited to give students more access to the cumulative staff knowledge and cutting-edge equipment at MIT.nano, which opened in 2018. Osherov is associate director for Characterization.nano, a shared experimental facility for advanced imaging and analysis.

“Our mission is to support mature researchers — and to help inspire the future PhDs and professors who will come to MIT to learn, research, and innovate,” Osherov says. “Designing and offering such programs, aimed at fostering natural curiosity and creativity of young minds, has a tremendous long-term benefit to our society. We can raise tomorrow’s generation in a better way.”

For her part, Ford is still coasting on the students’ excitement. “They come into the program so curious and hungry for knowledge. They remind me every day how amazing the world is.”

Want to get middle-school kids excited about science? Let them do their own experiments on MIT.nano’s state-of-the-art microscopes — with guidelines and adult supervision, of course. That was the brainchild of Carl Thrasher and Tao Cai, MIT graduate students who spearheaded the Electron Microscopy Elevating Representation and Growth in Education (EMERGE) program.

Held in November, EMERGE invited 18 eighth-grade students to the pilot event at MIT.nano, an interdisciplinary facility for nanoscale research, to get hands-on experience in microscopy and materials science.

The highlight of the two-hour workshop: Each student explored mystery samples of everyday materials using one of two scanning electron microscopes (SEMs), which scan material samples using a beam of electrons to form an image. Though highly sophisticated, the instruments generated readily understandable data — images of intricate structures in a butterfly wing or a strand of hair, for example.

The students had an immediate, tangible sense of success, says Thrasher, from MIT’s Department of Materials Science and Engineering (DMSE). He led the program along with Cai, also from DMSE, and Collette Gordon, a grad student in the Department of Chemistry.

“This experience helped build a sense of agency and autonomy around this area of science, nurturing budding self-confidence among the students,” Thrasher says. “We didn’t give the students instructions, just empowered them to solve problems. When you don’t tell them the solution, you get really surprised with what they come up with.”

Want to get middle-school kids excited about science? Let them do their own experiments on MIT.nano’s state-of-the-art microscopes — with guidelines and adult supervision, of course. That was the brainchild of Carl Thrasher and Tao Cai, MIT graduate students who spearheaded the Electron Microscopy Elevating Representation and Growth in Education (EMERGE) program.

Held in November, EMERGE invited 18 eighth-grade students to the pilot event at MIT.nano, an interdisciplinary facility for nanoscale research, to get hands-on experience in microscopy and materials science.

“Our students had an incredible time with the EMERGE team. We’re excited about the possibility of future partnerships with MIT.nano and other departments at MIT, giving our scholars exposure to the breadth of opportunities as future scientists,” says Eboney Hearn, MITES executive director.

With the success of the pilot, the EMERGE team is looking to offer more programs to the MITES students in the spring. Anna Osherov is excited to give students more access to the cumulative staff knowledge and cutting-edge equipment at MIT.nano, which opened in 2018. Osherov is associate director for Characterization.nano, a shared experimental facility for advanced imaging and analysis.

“Our mission is to support mature researchers — and to help inspire the future PhDs and professors who will come to MIT to learn, research, and innovate,” Osherov says. “Designing and offering such programs, aimed at fostering natural curiosity and creativity of young minds, has a tremendous long-term benefit to our society. We can raise tomorrow’s generation in a better way.”

For her part, Ford is still coasting on the students’ excitement. “They come into the program so curious and hungry for knowledge. They remind me every day how amazing the world is.”

There's a bridge in Japan that's so steep it's known as the Rollercoaster Bridge: the Eshima Ohashi bridge in Sakaiminato, which connects that city to nearby Matsue. Approaching the bridge from afar, it can appear nearly vertical to drivers.

Want to get middle-school kids excited about science? Let them do their own experiments on MIT.nano’s state-of-the-art microscopes — with guidelines and adult supervision, of course. That was the brainchild of Carl Thrasher and Tao Cai, MIT graduate students who spearheaded the Electron Microscopy Elevating Representation and Growth in Education (EMERGE) program.

Held in November, EMERGE invited 18 eighth-grade students to the pilot event at MIT.nano, an interdisciplinary facility for nanoscale research, to get hands-on experience in microscopy and materials science.

The highlight of the two-hour workshop: Each student explored mystery samples of everyday materials using one of two scanning electron microscopes (SEMs), which scan material samples using a beam of electrons to form an image. Though highly sophisticated, the instruments generated readily understandable data — images of intricate structures in a butterfly wing or a strand of hair, for example.

The students had an immediate, tangible sense of success, says Thrasher, from MIT’s Department of Materials Science and Engineering (DMSE). He led the program along with Cai, also from DMSE, and Collette Gordon, a grad student in the Department of Chemistry.

“This experience helped build a sense of agency and autonomy around this area of science, nurturing budding self-confidence among the students,” Thrasher says. “We didn’t give the students instructions, just empowered them to solve problems. When you don’t tell them the solution, you get really surprised with what they come up with.”

Unlocking interest in the infinitesimal

The students were part of a multi-year science and engineering exploration program called MITES Saturdays, run by MIT Introduction to Technology, Engineering, and Science, or MITES. A team of volunteers was on hand to help students follow the guidance set out by Thrasher, ensuring the careful handling of the SEMs — worth roughly $500,000 each.

MITES Saturdays program administrator Lynsey Ford was thrilled to observe the students’ autonomous exploration and enthusiasm.

“Our students got to meet real scientists who listened to them, cared about the questions they were asking, and welcomed them into a world of science,” Ford says. “A supportive learning environment can be just as powerful for science discovery as a half-million-dollar microscope.”

The pilot workshop was the first step for Thrasher and his team in their goal to build EMERGE into a program with broad impact, engaging middle-to-high school students from a variety of communities.

The partnership with MITES Saturdays is crucial for this endeavor, says Thrasher, providing a platform to reach a wider audience. “Seeing students from diverse backgrounds participating in EMERGE reinforces the profound difference science education can have.”

MITES Saturdays students are high-achieving Massachusetts seventh through 12th graders from Boston, MIT’s hometown of Cambridge, and nearby Lawrence.

“The majority of students who participate in our programs would be the first person in their family to go to college. A lot of them are from families balancing some sort of financial hardship, and from populations that are historically underrepresented in STEM,” Ford says.

Experienced SEM users set up the instruments and prepared test samples so students could take turns exploring specimens such as burrs, butterfly wings, computer chips, hair, and pollen by operating the microscope to adjust magnification, focus, and stage location.

Students left the EMERGE event with copies of the electron microscope images they generated. Thrasher hopes they will use these materials in follow-up projects, ideally integrating them into existing school curricula so students can share their experiences.

EMERGE co-director Cai says students were excited with their experimentation, both in being able to access such high-end equipment and in seeing what materials like Velcro look like under an SEM (spoiler alert: it’s spaghetti).

“We definitely saw a spark,” Cai says. “The subject matter was complex, but the students always wanted to know more.” And the after-program feedback was positive, with most saying the experience was fun and challenging. The volunteers noted how engaged the students were with the SEMs and subject matter. One volunteer overheard students say, “I felt like a real scientist!”

Inspiring tomorrow’s scientists

EMERGE is based on the Scanning Electron Microscopy Educators program, a long-running STEM outreach program started in 1991 by the Air Force Research Laboratory and adopted by Michigan State University. As an Air Force captain stationed at Wright-Patterson Air Force Base in Ohio, Thrasher participated in the program as a volunteer SEM expert.

“I thought it was an incredible opportunity for young students and wanted to bring it here to MIT,” he says.

The pilot was made possible thanks to support from the MITES Saturdays team and the Graduate Materials Council (GMC), the DMSE graduate student organization. Cai and DMSE grad student Jessica Dong, who are both GMC outreach chairs, helped fund, organize, and coordinate the event.

I’ve enjoyed reading magazine articles about Ethernet’s 50th anniversary, including one in the The Institute. Invented by computer scientists Robert Metcalfe and David Boggs, Ethernet has been extraordinarily impactful. Metcalfe, an IEEE Fellow, received the 1996 IEEE Medal of Honor as well as the 2022 Turing Award from the Association for Computing Machinery for his work. But there is more to the story that is not widely known.

During the 1980s and early 1990s, I led Digital Equipment Corp.’s networking advanced development group in Massachusetts. I was a firsthand witness in what was a period of great opportunity for LAN technologies and intense competition between standardization efforts.

DEC, Intel, and Xerox poised themselves to profit from Ethernet’s launch in the 1970s. But during the 1980s other LAN technologies emerged as competitors. Prime contenders included the token ring, promoted by IBM, and the token bus. (Today Ethernet and both token-based technologies are part of the IEEE 802 family of standards.)

All those LANs have some basic parts in common. One is the 48-bit media access control (MAC) address, a unique number assigned during a computer’s network port manufacturing process. The MAC addresses are used inside the LAN only, but they are critical to its operation. And usually, along with the general-purpose computers on the network, they have at least one special-purpose computer: a router, whose main job is to send data to—and receive it from—the Internet on behalf of all the other computers on the LAN.

In a decades-old conceptual model of networking, the LAN itself (the wires and low-level hardware) is referred to as Layer 2, or the data link layer. Routers mostly deal with another kind of address: a network address that is used both within the LAN and outside it. Many readers likely have heard the terms Internet Protocol and IP address. With some exceptions, the IP address (a network address) in a data packet is sufficient to ensure that packet can be delivered anywhere on the Internet by a sequence of other routers operated by service providers and carriers. Routers and the operations they perform are referred to as Layer 3, or the network layer.

In a token ring LAN, shielded twisted-pair copper wires connect each computer to its upstream and downstream neighbors in an endless ring structure. Each computer forwards data from its upstream neighbor to its downstream one but can send its own data to the network only after it receives a short data packet—a token—from the upstream neighbor. If it has no data to transmit, it just passes the token to its downstream neighbor, and so on.

In a token bus LAN, a coaxial cable connects all the network’s computers, but the wiring doesn’t control the order in which the computers pass the token. The computers agree on the sequence in which they pass the token, forming an endless virtual ring around which data and tokens circulate.

Ethernet, meanwhile, had become synonymous with coaxial cable connections that used a method called carrier sense multiple access with collision detection for managing transmissions. In the CSMA/CD method, computers that want to transmit a data packet first listen to see if another computer is transmitting. If not, the computer sends its packet while listening to determine whether that packet collides with one from another computer. Collisions can happen because signal propagation between computers is not instantaneous. In the case of a collision, the sending computer resends its packet with a delay that has both a random component and an exponentially increasing component that depends on the number of collisions.

The need to detect collisions involves tradeoffs among data rate, physical length, and minimum packet size. Increasing the data rate by an order of magnitude means either reducing the physical length or increasing the minimum packet size by roughly the same factor. The designers of Ethernet had wisely chosen a sweet spot among the tradeoffs: 10 megabits per second and a length of 1,500 meters.

A threat from fiber

Meanwhile, a coalition of companies—including my employer, DEC—was developing a new ANSI LAN standard: the Fiber Distributed Data Interface. The FDDI approach used a variation of the token bus protocol to transmit data over optical fiber, promising speeds of 100 Mb/s, far faster than Ethernet’s 10 Mb/s.

A barrage of technical publications released analyses of the throughputs and latencies of competing LAN technologies under various workloads. Given the results and the much greater network performance demands expected from speedier processors, RAM, and nonvolatile storage, Ethernet’s limited performance was a serious problem.

FDDI seemed a better bet for creating higher speed LANs than Ethernet, although FDDI used expensive components and complex technology, especially for fault recovery. But all shared media access protocols had one or more unattractive features or performance limitations, thanks to the complexity involved in sharing a wire or optical fiber.

A solution emerges

I thought that a better approach than either FDDI or a faster version of Ethernet would be to develop a LAN technology that performed store-and-forward switching.

One evening in 1983, just before leaving work to go home, I visited the office of Mark Kempf, a principal engineer and a member of my team. Mark, one of the best engineers I have ever worked with, had designed the popular and profitable DECServer 100 terminal server, which used the local-area transport (LAT) protocol created by Bruce Mann from DEC’s corporate architecture group. Terminal servers connect groups of dumb terminals, with only RS-232 serial ports, to computer systems with Ethernet ports.

I told Mark about my idea of using store-and-forward switching to increase LAN performance.

The next morning he came in with an idea for a learning bridge (also known as a Layer 2 switch or simply a switch). The bridge would connect to two Ethernet LANs. By listening to all traffic on each LAN, the device would learn the MAC addresses of the computers on both Ethernets (remembering which computer was on which Ethernet) and then selectively forward the appropriate packets between the LANs based upon the destination MAC address. The computers on the two networks didn’t need to know which path their data would take on the extended LAN; to them, the bridge was invisible.

The bridge would need to receive and process some 30,000 packets per second (15,000 pp/s per Ethernet) and decide whether to forward each one. Although the 30,000 pp/s requirement was near the limit of what could be done using the best microprocessor technology of the time, the Motorola 68000, Mark was confident he could build a two-Ethernet bridge using only off-the-shelf components including a specialized hardware engine he would design using programmable array logic (PAL) devices and dedicated static RAM to look up the 48-bit MAC addresses.

Mark’s contributions have not been widely recognized. One exception is the textbook Network Algorithmics by George Varghese.

In a misconfigured network—one with bridges connecting Ethernets in a loop—packets could circulate forever. We felt confident that we could figure out a way to prevent that. In a pinch, a product could ship without the safety feature. And clearly a two-port device was only the starting point. Multiple-port devices could follow, though they would require custom components.

I took our idea to three levels of management, looking for approval to build a prototype of the learning bridge that Mark envisioned. Before the end of the day, we had a green light with the understanding that a product would follow if the prototype was successful.

Developing the bridge

My immediate manager at DEC, Tony Lauck, challenged several engineers and architects to solve the problem of packet looping in misconfigured networks. Within a few days, we had several potential solutions. Radia Perlman, an architect in Tony’s group, provided the clear winner: the spanning tree protocol.

In Perlman’s approach, the bridges detect each other, select a root bridge according to specified criteria, and then compute a minimum spanning tree. An MST is a mathematical structure that, in this case, describes how to efficiently connect LANs and bridges without loops. The MST was then used to place any bridge whose presence would create a loop into backup mode. As a side benefit, it provided automated recovery in the case of a bridge failure.

Mark designed the hardware and timing-sensitive low-level code, while software engineer Bob Shelly wrote the remaining programs. And in 1986, DEC introduced the technology as the LANBridge 100, product code DEBET-AA.

Soon after, DEC developed DEBET-RC, a version that supported a 3-kilometer optical fiber span between bridges. Manuals for some of the DEBET-RCs can be found on the Bitsavers website.

Mark’s idea didn’t replace Ethernet—and that was its brilliance. By allowing store-and-forward switching between existing CSMA/CD coax-based Ethernets, bridges allowed easy upgrades of existing LANs. Since any collision would not propagate beyond the bridge, connecting two Ethernets with a bridge would immediately double the length limit of a single Ethernet cable alone. More importantly, placing computers that communicated heavily with each other on the same Ethernet cable would isolate that traffic to that cable, while the bridge would still allow communication with computers on other Ethernet cables.

That reduced the traffic on both cables, increasing capacity while reducing the frequency of collisions. Taken to its limit, it eventually meant giving each computer its own Ethernet cable, with a multiport bridge connecting them all.

That is what led to a gradual migration away from CSMA/CD over coax to the now ubiquitous copper and fiber links between individual computers and a dedicated switch port.

The speed of the links is no longer limited by the constraints of collision detection. Over time, the change completely transformed how people think of Ethernet.

A bridge could even have ports for different LAN types if the associated packet headers were sufficiently similar.

Our team later developed GIGAswitch, a multiport device supporting both Ethernet and FDDI.

The existence of bridges with increasingly higher performance took the wind out of the sails of those developing new shared media LAN access protocols. FDDI later faded from the marketplace in the face of faster Ethernet versions.

Bridge technology was not without controversy, of course. Some engineers continue to believe that Layer 2 switching is a bad idea and that all you need are faster Layer 3 routers to transfer packets between LANs. At the time, however, IP had not won at the network level, and DECNet, IBM’s SNA, and other network protocols were fighting for dominance. Switching at Layer 2 would work with any network protocol.

Mark received a U.S. patent for the device in 1986. DEC offered to license it on a no-cost basis, allowing any company to use the technology.

That led to an IEEE standardization effort. Established networking companies and startups adopted and began working to improve the switching technology. Other enhancements—including switch-specific ASICs, virtual LANs, and the development of faster and less expensive physical media and associated electronics—steadily contributed to Ethernet’s longevity and popularity.

The lasting value of Ethernet lies not in CSMA/CD or its original coaxial media but in the easily understood and functional service that it provided for protocol designers.

The switches in many home networks today are directly descended from the innovation. And modern data centers have numerous switches with individual ports running between 40 and 800 gigabits per second. The data center switch market alone accounts for more than US $10 billion in annual revenue.

Lauck, my DEC manager, once said that the value of an architecture can be measured by the number of technology generations over which it is useful. By that measure, Ethernet has been enormously successful. The same can be said of Layer 2 switching.

No one knows what would have happened to Ethernet had Mark not invented the learning bridge. Perhaps someone else would have come up with the idea. But it’s also possible that Ethernet would have slowly withered away.

To me, Mark saved Ethernet.

Epic has revealed the next titles it's giving away on the Epic Games Store, with Deux Ex: Mankind Divided and The Bridge getting the freebie treatment from Thursday, 14th March.

Deux Ex: Mankind Divided is the fifth instalment in Square Enix's stealthy, shooty sci-fi series and a direct sequel to 2012's Deus Ex: Human Revolution. Once again cyber-augmented protagonist Adam Jensen returns, and the ensuing adventure was deemed to be a "smart, handsome and weighty addition to the stealth-action genre" in Eurogamer's review.

As for The Bridge, it's a gravity shifting puzzle game created by Ty Taylor - and described as "Isaac Newton meets M. C. Escher" - that challenges players to manoeuvre the world and reach the exit each stage. Eurogamer quite liked this one on release in 2013, even if it sometimes felt like "the taster course for a more satisfying meal kept frustratingly off the menu."

Want to get middle-school kids excited about science? Let them do their own experiments on MIT.nano’s state-of-the-art microscopes — with guidelines and adult supervision, of course. That was the brainchild of Carl Thrasher and Tao Cai, MIT graduate students who spearheaded the Electron Microscopy Elevating Representation and Growth in Education (EMERGE) program.

Held in November, EMERGE invited 18 eighth-grade students to the pilot event at MIT.nano, an interdisciplinary facility for nanoscale research, to get hands-on experience in microscopy and materials science.

The highlight of the two-hour workshop: Each student explored mystery samples of everyday materials using one of two scanning electron microscopes (SEMs), which scan material samples using a beam of electrons to form an image. Though highly sophisticated, the instruments generated readily understandable data — images of intricate structures in a butterfly wing or a strand of hair, for example.

The students had an immediate, tangible sense of success, says Thrasher, from MIT’s Department of Materials Science and Engineering (DMSE). He led the program along with Cai, also from DMSE, and Collette Gordon, a grad student in the Department of Chemistry.

“This experience helped build a sense of agency and autonomy around this area of science, nurturing budding self-confidence among the students,” Thrasher says. “We didn’t give the students instructions, just empowered them to solve problems. When you don’t tell them the solution, you get really surprised with what they come up with.”

Unlocking interest in the infinitesimal

The students were part of a multi-year science and engineering exploration program called MITES Saturdays, run by MIT Introduction to Technology, Engineering, and Science, or MITES. A team of volunteers was on hand to help students follow the guidance set out by Thrasher, ensuring the careful handling of the SEMs — worth roughly $500,000 each.

MITES Saturdays program administrator Lynsey Ford was thrilled to observe the students’ autonomous exploration and enthusiasm.

“Our students got to meet real scientists who listened to them, cared about the questions they were asking, and welcomed them into a world of science,” Ford says. “A supportive learning environment can be just as powerful for science discovery as a half-million-dollar microscope.”

The pilot workshop was the first step for Thrasher and his team in their goal to build EMERGE into a program with broad impact, engaging middle-to-high school students from a variety of communities.

The partnership with MITES Saturdays is crucial for this endeavor, says Thrasher, providing a platform to reach a wider audience. “Seeing students from diverse backgrounds participating in EMERGE reinforces the profound difference science education can have.”

MITES Saturdays students are high-achieving Massachusetts seventh through 12th graders from Boston, MIT’s hometown of Cambridge, and nearby Lawrence.

“The majority of students who participate in our programs would be the first person in their family to go to college. A lot of them are from families balancing some sort of financial hardship, and from populations that are historically underrepresented in STEM,” Ford says.

Experienced SEM users set up the instruments and prepared test samples so students could take turns exploring specimens such as burrs, butterfly wings, computer chips, hair, and pollen by operating the microscope to adjust magnification, focus, and stage location.

Students left the EMERGE event with copies of the electron microscope images they generated. Thrasher hopes they will use these materials in follow-up projects, ideally integrating them into existing school curricula so students can share their experiences.

EMERGE co-director Cai says students were excited with their experimentation, both in being able to access such high-end equipment and in seeing what materials like Velcro look like under an SEM (spoiler alert: it’s spaghetti).

“We definitely saw a spark,” Cai says. “The subject matter was complex, but the students always wanted to know more.” And the after-program feedback was positive, with most saying the experience was fun and challenging. The volunteers noted how engaged the students were with the SEMs and subject matter. One volunteer overheard students say, “I felt like a real scientist!”

Inspiring tomorrow’s scientists

EMERGE is based on the Scanning Electron Microscopy Educators program, a long-running STEM outreach program started in 1991 by the Air Force Research Laboratory and adopted by Michigan State University. As an Air Force captain stationed at Wright-Patterson Air Force Base in Ohio, Thrasher participated in the program as a volunteer SEM expert.

“I thought it was an incredible opportunity for young students and wanted to bring it here to MIT,” he says.

The pilot was made possible thanks to support from the MITES Saturdays team and the Graduate Materials Council (GMC), the DMSE graduate student organization. Cai and DMSE grad student Jessica Dong, who are both GMC outreach chairs, helped fund, organize, and coordinate the event.

The MITES Saturdays students included reflections on their experience with the SEMs in their final presentations at the MITES Fall Symposium in November.

“My favorite part of the semester was using the SEM as it introduced me to microscopy at the level of electrons,” said one student.

“Our students had an incredible time with the EMERGE team. We’re excited about the possibility of future partnerships with MIT.nano and other departments at MIT, giving our scholars exposure to the breadth of opportunities as future scientists,” says Eboney Hearn, MITES executive director.

With the success of the pilot, the EMERGE team is looking to offer more programs to the MITES students in the spring. Anna Osherov is excited to give students more access to the cumulative staff knowledge and cutting-edge equipment at MIT.nano, which opened in 2018. Osherov is associate director for Characterization.nano, a shared experimental facility for advanced imaging and analysis.

“Our mission is to support mature researchers — and to help inspire the future PhDs and professors who will come to MIT to learn, research, and innovate,” Osherov says. “Designing and offering such programs, aimed at fostering natural curiosity and creativity of young minds, has a tremendous long-term benefit to our society. We can raise tomorrow’s generation in a better way.”

For her part, Ford is still coasting on the students’ excitement. “They come into the program so curious and hungry for knowledge. They remind me every day how amazing the world is.”
