  2. When I see long distance, low frequency waves carrying energy all the way from a storm to the coastline, that's just swell.

  5. One could say the guys making aerogels are aerosmiths. Steven Tyler would be proud.

  6. As an Aerospace Engineer, first thought was absolutely, no way this works. Then I remember tacking sailboats, right before you mentioned them, and thought, okay maybe this is possible. The last explanation was fantastic and clearly demonstrates it is possible. There is a lot of energy in that wind, the propeller just allows you to pull a bit more energy out than you would otherwise be able to.

  7. You know what was amazing, is to see such excitement of every person interviewed in this video, including you Derek! Truly amazing, what a great future!

  8. I feel that "Metersen's colleague" should definitely get at least a name check here! So, hat tip to Sven Skyum, reader emeritus at Department of Computer Science, University of Aarhus.

  9. What happened to the redefinition of the kilogram video?

  10. The level of precision needed to correct spherical aberration is mind-blowing. Seeing atoms clearly was once a dream; now, thanks to innovation, it's a reality.

  11. 3:38 I love his sense of humor. "We know who's fault this is" lol!

  12. "We’re still getting big plants, and they wouldn’t grow that well if they weren’t getting the nutrients they need" Not true. You get large leafy plants by adding nitrogen, farmers do that in spades to increase yields. But nutritional content comes from micronutrients, and farmers have been depleting those for 60 years. It’s a similar dilution mechanism to the one described for CO2. Adding climate change into the mix would exacerbate the problem. In short, it doesn’t have to be one or the other.

  13. As a first year physics student, these types of videos are incredibly valuable! I legitimately cannot explain how incredible it is to walk the line of simple explaination vs specificity and detail that you and your team walk perfectly. Thank you so much, it makes me so happy that there are science educators such as yourself following in Euler's footsteps, teaching with empathy, clarity, and clear passion!

  15. As a 33 year old who doesnt feel he has reached his lifes purpose or dreams, a guy who lives alone without a family.... your story fills me with hope and inspiration for my future. Your reflection is so deep and your content now is better than its ever been. THanks for sharing :)

  16. Still going strong after all these years. And not a bit of quality loss. Love it man. Thank you.

  17. As an ex-aerodynamicist, you bring back many happy memories of using Schlieren systems to investigate transonic flows over a whole bunch of different shapes. You might like to try to produce "colour Schlieren", where you replace the razor blade with a discrete colour filter - we used to use different coloured bits of transparent gel used in theatre lighting. The only problem is to get the filter small enough to produce the desired colour changes. But it's great fun trying! Good luck.

  18. We may now know the secret of synchronization, but we will never know the secret to how Veritasium edits his videos so impeccably smoothly.
    637
  19. Veritasium in the last year or two has really revived my hope that youtube science can be more than either crazy conspiracy videos or purely informational. He's doing the closest a pop-scientist has done to science since the mythbusters, and he's arguably added the important step of peer review into his process.

  20. 4:24 "confirming beyond a shadow of a doubt" WHY ARE YOU LIKE THIS?
    631
  21. That 37 one dollar bills each with the number 37 is a true act of love from his mother. Beautiful.

  22. My opinion is that your videos have extremely high quality and educational value. I think you could be producing documentaries for Netflix, BBC, PBS more often
    630
  23. Your videos never feel like they’re 20 minutes long! There’s always so much research into topics that we would’ve never known if not for your videos. Love the content.

  24. You and Tom Scott have been making things for everyone on youtube for longer than some of your newer audience has been alive. This scale of time scares me aha.
    623
  25. Really appreciate all the effort you went to in making this video, you’ve put a lot of time and effort in.

  26. The analog computers used by navies during the First and Second World Wars are amazing technological feats. The inputs are the continuous, relative motions of opposing ships and the outputs are a synchronous stream of firing solutions.
    607
  27. You inspired me to pick physics as my major
    606
  28. I still haven't taken it apart to look but i assume its probably easily fixable. I think the cold from the propane tank broke something internally ironically

  29. Earlier this summer, I went on a short night hike with some rangers in Copper Breaks State Park, Texas. We took UV flashlights and our group counted about 70 scorpions along the way. Until that night, I had no idea that they glowed!

  30. Someone below is asking that the rolling code can't work the way its told here. As if the receiver accepts only the next code what will happen if the transmitter is out of range and someone presses the button of transmitter ? As now transmitter has moved ahead of receiver. Well the video lacks a few things here. Actually there is a synchronization counter C which gets increamented each time you press the key (of transmitter). Same way the receiver also stores the most recent validated synchronization counter it has received (N). Now when ever you press the key and send the pseudo-random number to the transmitter the transmitter also takes the synchronization counter C from transmitter (and to update itself will overwrite N with C). Now receiver will also produce the Cth code (corresponding to C i mean) and match with the code send by transmitter. There is also rolling window of acceptance for rolling codes say 100 or 1000 or whatever (depending upon which system you using for your garrage or car keys). Now also note that C-N <= window of acceptance. Hope you are getting my point here. Means if you window of acceptance is say 1000 and you press your key 1000 times when you were out of the range then the garrage (or your car or whatever) will ignore the key even if you come back to range. Also note that if press the key and hold it pressed it keeps emitting same bits, its only when you press it again (press, release the button and press again) that you are generating a new code. The attack works because the tranmitter checks if the next number is what falls in the sequence and there is no concept of expire due to time here (like we have in one time passwords sent to phone).

  31. Wow what a wholesome video. You can see how passionate he is with everything he does, and most importantly he always had a pattern: shift to something else when deemed necessary. And now he's shifting his time to spend it with his family, which I think is the most important thing shown in the video...Seriously loved this video so much, thank you

  32. if it was just 1 minute and 1 second shorter, 22:49, it would've been 37x37 seconds long

  33. What I love about this is that this is truly an application of the scientific method within the scientific community. One person (or group) makes an experiment and hypothesis, peers challenge/prove/disprove the original hypothesis, and experiment with their own experiments, explanations, and hypotheses, and then communicate back to the scientific community. This results in further testable hypotheses and finally consensus. Those that question science sometime feel that science is a collection of edicts set in stone foisted upon them by the elite, but science is beautiful because it demands challenge for it work! I wish I were a writer to explain my thoughts better, but this video and situation surrounding it were simply too inspiring not to comment on.

  34. Veritasium: I’m going to be making more clickbait titles moving forward. Also Veritasium: makes intriguing titles which perfectly reflect the content of the video AND draw in new viewers.

  35. You know its deadly serious when Veritasium says "we are approaching spooky teritory"

  36. People really need to remember that most engineering-centric views of the world are, at their core, useful simplifications. Just like how an electrical engineer doesn't need to think about quarks when discussing how semiconductors work (since it is more or less "irrelevant"), an electrical engineer also doesn't need to "fully" consider how energy is actually dissipated to a load, but instead must simply understand and be able to model (with a sufficient degree of accuracy) what is happening. As a computer engineer, I also like to think of this as an abstraction, similar to how someone writing software really doesn't need to understand "exactly" what the CPU is doing in order to sufficiently write a piece of software (unless you are obviously writing low-level code which interacts with assembly or something).

  37. From watching objects being destroyed in slow-mo I'm finally learning new things an effective way. Derek, thank you so much.

  38. heat up a popcorn kernel until it pops.

  39. I'm continuously blown away more with every video by the production value and quality veritasium has reached. It is insane to think that this is youtube now... i mean, writing, editing, animations, plot/subplot, interviews, the "red line" through the whole video... yep... blown away
    573
  40. Wow.. What a nice video.. Thanks so much for creating this video..!! I believe the world would be a better place because of it 😊
    568
  41. Thank you Derek for making such great videos. Especially this one touched my heart. I am a mechanical engineer and I work in the field of dynamics. I have never understood why there are two ways how to get motion equations - at the university, I used Newton's second law most of the times, because it was straightforward. I did't understand, where the Lagrange's equatins came from. Now I know. And I am touched by the fact that each of those great mathematicians added a small pice of puzzle into this picture. And I feel sad for Mapertuis who died without knowing, that his theory was proven to be correct. Thanks for reminding us the important people, that were forgotten throughout the history.

  42. I'm a theoretical physicist, and I'm astonished by how precise and well-presented the video is. It reminded me of the wonder I felt as an undergraduate attending beautiful lectures on classical mechanics. Thank you for creating such wonderful material for everyone on YouTube.
    564
  43. I work in meteorology with part of my job being to photograph and determine which types of snowflakes are falling at a given time. Basically I travel around Canada chasing horrible winter weather to take measurements and identify snowflakes. Love the video! You just made my week.

  44. YOU'VE MET ROBERT LANG?!

  45. What i found with my own scorpions is that after they molt they are not florescent under black light untill their exoskeleton hardens again.
    557
  46. The QD Code at 13:07 didnt disappoint
    548
  47. This really put a smile on my face, it is brilliant, a mathematically philosophical masterpiece! Really brings hope into a seemingly hopeless world!
    545
  48. Amazing! I've seen this video weeks ago, but just came back to say: I love it.
    543
  49. Currently a semester away from completing my undergraduate degree in microbiology, and wow... The visuals, explanations, and connections between everything in this video is amazing. Videos like this are what make YouTube such a valuable learning resource.
    542
  50. I felt all the feels watching this. I've been going through my own emotional turmoil and procrastination that just makes it worse. This video is almost eye opening to a point where I think I need to make a change. I'll be coming back to this video to remind myself
