Same!
Yeah, me too.
But then again, it does say *grad* strudies.
For being a 3rd place, this is a 1st in my book.
âBrocc-umentaryâ
damn you.

Lol
Ok
I thought it was gonna be a shitpost, the car on a burger was perfect as a quick transition lol. It was really good as a quick layman explanation of your work in just 60 seconds, holy shit
post irony! *post irony!* _sobbing the words "post irony" under a green blanket run through a to greenscreen filter and overlayed on a muted video of shrek_
What
@@RidgeVR post irony
@@Tooooooom ah that explains everything.
I thought the same too haha
That transition at the end from silicon, to road, to wifi symbol was slick as fuck. If you got 3rd I can't imagine what got in 2nd and 1st.
Thats what she saidâŠ..
Perhaps the second did the same thing, with RTX on
haha motion graphics go brrr
@Ganheso Leso do it better
@@peternystrom921 how?/
Ngl that transition from the car to the burger was filmmaking genius, if it werenât so low poly Iâd give you an award just for that
And the silicon and blood cell making a wi-fi symbol at the end too.
I kinda like how low poly it is
The issue is not the low poly, as a low poly 3D artist, it can look amazing! The lighting and texturing here is just very boring (which is understandable, he was probably busy enough with the modeling and animation) If it was lit differently it could make a huge difference!
The animation is great, it gets the message to the point, and all within a 1 minute timeframe. The quality is comparable to a shitpost meme, and i personally think that its elevating the animation value
yes
the phrase "quick and accurate blood tests" gives me PTSD to Elizabeth Holmes' Batman voice.
lmao very true. If you want to know how it'd work with photonics though, different blood types each have a slightly different refractive index. So if you can come up with device that can perceive slight changes in refractive index, you've got a sensor
@@BobbyBroccoli i didnt know you could utilize light as a way to measure blood type. Thats pretty cool
Same
We already have one quick and accurate light based blood test: transmissive pulse oximetry (aka that little thing they clip on your finger to measure oxygen saturation)
yep
Hello everyone! This video is a little side project I made for a school contest. It was a good excuse to learn Blender, which I'll be using for something big in the near future đ. Btw, I have a Patreon now (see description), which is set for every big brocc-umentary I make. Thanks for watching!
Will you also do a tutorial for blender?
@@jacknack6819 At some point yes!
@@BobbyBroccoli Why do you not rendered this? In cycles or eevee
Dude this is cool
It reminds me of those early 90s CGI type of videos
@@soupborsh8707 why would he
This has fun design, it's something straight out of like a good early 90s commercial, great job on getting 3rd place
How are you able to bend light with the silicon? This sounds like a very interesting topic.
So the main idea is that light tends to flow towards areas where the refractive index is higher. Silicon has a fairly high index compared to air (3.5 vs 1.0). The idea is you shape silicon strips into bends so that the light can turn at 90 degrees. The trick is that light reflects and bounces around different types of geometries, and finding the ideal curve for minimum loss takes a lot of simulation and testing.
@@BobbyBroccoli That's pretty neat. What kind of scale does this work on, like could you "print" photonic components at the same scale as current electronics? Or is it bigger/smaller?
It actually reuses a lot of the same fabrication and technology as electronics, just instead of voltages you pump lasers into the chips. My circuits have a minimum feature size of 60 nanometers for instance, and my chip size is 9 millimeters by 9 millimeters.
I would say that photonics has a higher size limit than electronics. Electrons can flow on the scale of individual molecules, but photonics depends on the size of the wavelength (around 1500 nanometers), and the silicon chunks can't be much smaller than 100nm
@@BobbyBroccoli Do you think we would start seeing photonics in pesonal computers in the future? Or would this be more for use in specialized equipment and networking?
UPDATE: My work in this video just got published in Advanced Materials Technologies as "Subwavelength Grating Metamaterial Multimode Bend for Silicon Waveguides"
So this video has gotten caught up in the algorithm *somehow*, and a lot of new comments asking recurring questions. Here's my attempt to answer them:
1. Isn't this what fiber optics is for?
Yes! But optical fibers are typically used for long-haul communications, i.e. hundreds of kilometers. Fiber optic cables have the advantage of better bandwidth (more data capacity) than sending it as electrical signals in say, coaxial cables. But then once the data gets to its destination, you need to convert it back into electrical signals, do some calculations with it on a chip, convert it back to light, and send it out again. Lots of steps, lots of expensive hardware. Being able to keep all that data as light and process it on a photonic chip would be ideal, and that's where my research lies.
2. Why not use mirrors?
When the size of the geometry is around the same scale of the wavelength of light, the physics of light starts to behave weirdly. In my case I'm making photonic integrated circuits with light of 1550 nm, and silicon segments around 220 nm. At that scale mirrors and total internal reflection don't really function in the same way. You can design a 45 degree corner facet and it does much what you're probably imagining, but it needs to be significantly bigger than other possible solutions like my silicon curved strips.
3. Some of this feels like a huge simplification/misleading.
It very much is. This video was my submission to a 1-minute thesis competition, and I ended up getting 3rd place! A field like photonics has a lot of jargon and technical terms, and I knew I had to go for showmanship if I wanted to stand a chance against other grad students who had more intuitive and easy to grasp topics. Are photons literally faster than electrons when it comes to data transmission? No, but it gets the point across in a 60 second time-limit.
4. Can I get more detail?
Sure! I have a video where I delve into more detail on my Master's work on my channel. And if you want to dive even deeper than that I'd happy to share my thesis upon request. My research is on silicon on insulator (SOI) photonic integrated circuits (PICs) using subwavelength gratings (SWGs).
5. Ew self driving cars
That's just the main example people in the field give for the application of LiDAR and optical-phased arrays for beam steering. I reality it can be used in industrial automation, aerial topography, etc. I don't think we're anywhere close to self driving cars, and that's purely from a hardware standpoint, I'm not even going to get into the machine learning and safety aspects
Dumb question but how do you know when a videos been hit by the algorithm? I mean you noticed this one which is crazy
When you start getting comments like "no idea why this was recommended to me" you know something is happening, that and the views for the last 48 hours spikes and most of them come from Browse features
@@BobbyBroccoli did you mean to pin this comment? because this seems like a very pin-worthy comment
also since I'm commenting might as well add that I've been following your channel since your first post on r/jon_bois and I just noticed how much you grew. I always hoped that the algorithm will pick your channel up, glad to see that it happened
We already have self driving cars, my friends.
Make tutorial
I like the low-poly look a lot. Aesthetically it feels like something made in the early 90s and shown on public broadcasting during an odd time slot. And I mean that in the best way possible. Itâs cozy, not boring.
Simple,informative,engaging
3 key features for a good presentation
I thought this would be a giant meme, but this video has left me pleasantly surprised and wanting to learn more.
Idk why youtube recommended this to me but I love it, I honestly thought it would be a joke but its really good. Not only is the interesting information conveyed in an understandable manner and easily followed, the animation supports the script really well.
electron-ics
woah
also that blood cell to wifi icon animation was pretty smart
This is such an awesome idea! I love this! I'm interested to know how patternscan improve light bandwidth (or throughput)?
the fuck you saying lol
@@ner0b what the fuck are YOU saying?
Shit that's 251 smart people who understood this comment but not me
@@aksunonair No its 252. You may not have understood this comment but there is no doubt you are smart :)
How "patterns can" or how "pattern scanning"?
I love how everyone is giving genuine feedback. Great job mate
your blender skills are looking good! excited to see what you have planned!!!
Man this comment aged well
â@@muhammadidrees7571Yes this comment aged beautifully
at this point i have no idea why you're at DUCKING 3RD PLACE
THIS IS A MASTERPIECE
Itâs very good, but not a masterpiece.
i disagree
That was so informative and entertaining. You're not just making a great stride in Photonics, but also making edjutainmemt viable.
Of course this got in the top 3! This was awesome. Very good intro to the subject. It's enough to leave you satisfied, but also has the right amount of interest to make you want to learn more. Very cool. đ
Great animation. Simple but effective. You can see how all the concepts link together in a visual format!
the transitions for that jon bois flare, great work!!
This is amazing showmanship indeed! Extraordinarily creative!
This level of succinct and clear information is what every âthinkpieceâ or video essay on this godforsaken platform should aspire to.
Great job on bringing photonics down to a level that even children could understand. Very nice video, Mr Broccoli.
The visuals definitely compliments the simplified explanation well. Good job for a 1 minute presentation.
I'm impressed by your creative transitions between objects! It really shows your talent.
I can see why you placed so well : )
0:12 fun fact, electrons are actually really slow, the reason they appear fast is because there is a long chain of them already filled in the circuit, just not moving yet. That's why it appears instant, because you're just moving the chain, electrons actually only move 1mm per second
that's very interesting
Wait don't electrons have a variable speed like normal particles. So their speed depends on how fast you push them. Or am I tripping.
This is a great one, thanks recommendations. It's definitely got a very interesting premise, it's probably got issues that I'm not qualified enough to know about but it's cool as hell to think about.
Congratulation stranger. I really like to see these types of creative projects
Great video my guy!
Sounds similar to using fibre optic cables? I don't study any of this stuff so I'm barely familiar, but I liked the animation!
Yes, but fiber optics are for very long distances, hundreds of kilometers. I make bends for circuits smaller than a fingernail!
was just about to write that in the comment section
Okay, that was admittedly, pretty good, first impressions of aesthetic 3D graphics aside - especially because I myself am learning this stuff aswell, making me all the more aware of how difficult it is to get to that stage in modeling and smooth transitions between each and every part of a video.
Ooh, wasn't expecting to nerd out about that kind of research, that's so interesting!
this was really good
no wonder you got at least 3rd place
very well done!
dude the transitions are so genius!!
This is very well made and informative, well done!
I've always wondered what alternatives to electricity might be possible. As a child I wondered if it may be possible to use Protons in the way we use electrons (so, like, Proticity?) to do things like making two opposite direction signals in the same wire or making devices that can have major parts swapped out for the opposite energy type to do unique things
That almost certainly wouldnât work well, nuclear reactions for transmitting information would probably be unpredictable and just less useful than electrons.
(I think, Iâm no expert)
We already use protons to produce electricity in lead-acid battery cars
Funny you should say that because when electricity was first discovered, it was posited that electricity was the movement of positive charges, something like a proton. A lot of our early fundamental understanding of how circuits works was based on that assumption of moving positive charges. It turns out that except for the description of some more complicated effects in circuitry, it is a perfectly viable model to understand a circuit as movement of positive charge. If you imagine the flow of electricity as an electron moving into a gap to form a new gap where that electron used to be, and then the electron behind it moving into that gap to form yet another new gap further back, etc. etc., then you arrive at the flow of electrons in one way, but the 'flow of gaps' in the other way. The gaps are nothing and so they have no/neutral charge, but neutral charge is positive relative to an electron's negative charge. So in a sense, electricity already works in the way you dream. Electrons flow one way, 'gaps' flow the other. Negative one way, positive the other.
Protons can't flow in a wire, but they can diffuse through water (for example) across concentration gradients. Protons dissolved in water is called an acid (an arrhenius acid, to be precise). Your body uses proton gradients all the time. These gradients are essential for some of the most vital processes of life, such as creating ATP in the mitochondria of our cells. Your body runs on "proticity"!
@@aureo5857 Yes, but as a reactant to a chemical reaction, not as a flowing charge that itself constitutes electricity, or 'proticity' as OP describes. The protons themselves are not flowing through a wire to create electricity. The 'electrochemical potential' of the battery cells provides the energy for electrons to flow and create electricity. That is, the reactants influence electrons to flow through the wire, and these electrons guide the reactions of the protons (from sulfuric acid), lead, and lead oxides to from water and lead sulfates.
@@nickklavohn4854 really interesting bud, thanks for the clarification
Those 60 seconds made me feel like I was ready to be more involved some sort of expanded understanding with light over electronics than ever.
The animation just so good!!! So smooth!!!
kudos for the project, really cool transitions
Oh my god this is so fucking cool. I want to study photonics.
It deserves 1st place, not 3rd
Not only is the transition sick af, the video is really informational as well. Totally deserved
youre so talented love this and your channel
Bro from did you learn using blender? This is great.
I mostly just binged a bunch of tutorials. The officialy blender ones are a good first start, but then I looked up specific stuff I wanted to do, like "how to make a gradient sky", "how to animate EM waves", how to animate electricity", etc. The rest is from my experience with Google Earth and video editing.
Once I release my next video I think I'll be making a Blender tutorial for my workflow, but it'll be a few months. If you have specific questions in the mean time feel free to ask me!
@@BobbyBroccoli Google Earth? How did that help? Also thank you for replying. Can I be in touch with you outside of CZcams?
Check out my tutorial on Google Earth, I used it to animate my Hendrik Schon series. I took inspiration from Jon Bois, a youtuber who basically invented the animation style I've used in my documentaries. He does amazing sports related content. Feel free to add me on twitter (@bobbybroccole) or discord if you prefer.
@@BobbyBroccoli Discord sounds better as I have been very active on discord lately. What's your ID?
RE: 0:12
It's not the flow of electrons that you should be focusing on, rather the flow of energy through electric fields because electrons themselves move at really really slow speeds yet the speed the actual energy moves at is a completely different situation.
Someone watched that Veritasium video. It does not matter which way you view electricity. Most Ph. D and professional electric engineers still speak about "electrons flowing" because it's a good analogy and it might as well be true. You don't have to correct anyone because what he said is perfectly fine.
@@lysikasaito i don't know what veritassum is?
@@akjm9177 There was a popular video by the CZcamsr Veritasium that talked about this topic in a bit of a reactionary way.
Awesome job, dude! Glad the algorithm picked up on this vid.
This is Really Great! Thanks for posting this!
Wouldnât using photons instead of electrons fundamentally change how circuits work
Not really if you just convert light to electricity or vice versa at the destination
@@kirtil5177 the goal was to convert light to electricity as little as possible
Your name is Kevan not BobbyBroccoli? I have been lied to my whole life
this guy went from *this* to making some of the most in-depth science history documentaries about niche (for the avg person) science topics. the early foundations of the transitions and camera movements shown here literally went on to become part of his niche story-telling style
Everything from the fast food transition to the explanation of photonics is just IMMACULATE
isn't this just optic fiber?
The last sentence is figuratively and is literally untrue.
But it got me 3rd place and audience's choice, so I'm not complaining
@@BobbyBroccoli you learned a lot from schon didn't you
"literally" (taking about the video btw)
with the last sentence removed you could've gotten 1st place
@@BobbyBroccoli You could say, "We're literally innovating *with* the speed of light"
This is very cool! Glad you got into a university
I just love that I can tell you've attended the Jon Bois school of cool editing
This is wrong and misleading. The speed of light in most *photonics* applications, where light travels through solid mediums, it's often **slower** than electric fields in wires, due to refractive index. Surely if you're working on this topic, you should know that? Keep bending light and not the truth.
I dunno anything about the topic, but based on what you said, I'm guessing there are specific uses for photonics in which it would be faster than electric fields in wires? Also, didn't he say in the video that people are trying to find ways to circumvent the issue of refraction and make photonics generally faster? It's not like he's trying to sell a product, so I don't really see much harm in what he said. If anything, the people who are interested enough in the topic can go on to do their own research
What they said! If you want to know more watch my Master's speedrun video.
Nice job! Really informative!!
I was waiting for a skip ad option the whole video, good job
Really smooth transitions and audio work there!
I watched this with no audio without realizing and it's the funniest thing I've seen all week
The transition is so smooth!
This definitely deserves a podium placement. There is literally nothing that could be removed that is considered excess and all graphics supplement the talking points in real time to help the viewer visualize your message.
Thatâs top quality.
This was a really great presentation/video. Totally expected it to be a meme
Short, quick and genious!
its so well done it makes me smile
the last line was so clean
This is it. This is the random video on my recommendation tab that got youtube to recommend your channel again and send me into a rabbit hole
this is amazing. good job
I did my high school senior year major physics essay on photonics (in 2020) and it was extremely hard to grasp for me, as it was outside the course outline. I managed to get a decent grade but the time put in trying to wrap my head around this concept was astounding! I wish this video was around, it explains it so simply. Well done!
That turned way better than expected! âïž
The transitions are exceptional.
The way you transition in this video is brilliant
This is so professional and cool!
This was Very good, the transition to the Wi-Fi was Smooth AF
Was definitely expecting a sort of âlearned 3D animation to make thisâ thing but this is legitimately great and super informative
Great video. Your voice definitely helps the video alot.
Awesome piece, awesome script.
Super nice looking video, hope you had a good time, I'm sure the other people were impressed
Outstandingly awesome presentation
That is genuinely well made, the animation is ok but like the idea and shit is good damn xd
This is really nice, congrats.
Im intressted to see who got 1st and 2nd place!

This is the most professional quality "shitpost" I've ever seen. I kid you not, this is good.
I'm not surprised this placed this has seamless, slick transitions
Love this, itâs like animated 5 minute papers
This is really good simple soothing voice and great animations keep it up
This is genuinely so cool
With this video you:
1. Taught people about a complex subject without being verbose
2. Pitched your idea clearly and concisely and,
3. Kept your viewers interested with slick visuals illustrating your points.
I hope you get the job of your dreams, because clearly you're capable of amazing work.
As a layman, I have only a rough understanding of what you talked about here, but it sounds fascinating and great for the future. I wish I could help you with your research, but that's all _way_ above my pay grade!
The algorithm found you.
I'm just doing my part.
Take my like and I hope that your work in Photonics goes greatly.
The visuals are so entrancing
The algorithm has blessed you, my friend
this is a cool video! genuinely very good!
