  1. Clearly they never heard of the Raytheon knife missile either… shoulda consulted with Robert Evans.

  2. Now you understand the idea of “education is wasted on the young.” If you taught this outside of graduate school, 99% of students would just ask if it’s on the midterm and ignore it. IMO the answer isn’t to make this part of a mandatory standardized curriculum. It’s to make these kinds of videos easier to find for those who are interested and provide support for independent study. One way to do it in a grade school math context could be to have a pool of 10s of videos like this, and have students write a short (<= 1 page) summary paper on a video of their choice.

  3. @ayush gupta I don’t think you have to be an idiot to find FFT dry. You just need to be taught it by someone who hates teaching, and is very lazy and mechanical in their explanation. All too common in the modern university, where publish or perish dominates everything. Teaching is an irritating distraction from research for too many professors. Lectures are to professors as meetings are to software engineers.

  4. Whoever greenlit Operation Chrome Dome must’ve had a pack a day crayon eating habit…

  5. Also Raytheon’s knife missile team for the projectile design.

  6. Raytheon’s getting a lot of data for future rods of god from those knife missiles…

  7. I figured out from the first video what was happening, but I had to go back to the Poynting vector diagram and combine that with the tidbit about transmission wires needing enough air gap to avoid arcing to ground. Those circuit simulations make it so much clearer.

  8. @Frotoe god bless Dr Smith, the purest of pure mathematicians. It’s true. Many mathematicians don’t really care if it’s useful or not. In fact it seems to be a point of pride among some to work on the least useful math imaginable. But then people said that about number theory and now it secures the entire internet so you don’t know what’ll be useful someday

  9. This is what gets lost in the noise of all the AGI BS. It’s shameful how much capital is wasted on Sam Alt-Man’s grift when this is what can actually be accomplished by scientists with sufficient funding.

  10. Ski the east, you’ll never have to worry about this while skidding down 2000 vertical feet of hockey rink ice

  11. I realize I’m benefitting massively from hindsight and the condensation of 50 years of CS into algorithms courses and texts, but it feels so obvious of a speedup to me! Was the fundamental periodic nature of sine/cosine waves not reflected in textbooks and schools at the time? Just sketch a small example out, and you see there’s repeated computations… How in the world did it take them over a year to publish it?! I wonder if it could have been published in 1963 if that IBM programmer knew how high the stakes were. I’m just picturing them blowing this helium spin thing off for months in favor of some pointless mainframe crap for a bank. Imagine finding out later, you could’ve had such a massive impact on the world if someone decided you needed to know enough info to make it your number one priority for the next month. Sigh…

  12. “Never argue with an idiot, they will drag you down to their level and beat you with experience.” Smart people are so exhausted by a lifetime of dealing with morons, that sometimes they just forget training and let the confirmation bias autopilot take over. Also, doing this study as a “man on the street” is obnoxious. It’s seemingly designed to cause people to skip steps and take shortcuts. Let them use a pen and a piece of paper and see if the answers change.
