To explain this effect, I printed out the same maze but made of plastic trenches and not metal foil. By running water through this plastic maze, we can learn something about how electrons flow in metals. This analogy does have some limitations that you need to keep in mind, but for the vast majority of cases, I think it does a FANTASTIC job at modeling bulk electron behavior in "1D" wires.
At the end of the video, I have a few more mazes that have two solutions each, to test the "path of least resistance" adage.

I also show off a woodblock printing I made using that laser cutter, replicating the graphics from the opening of The Legend of Zelda the Wind Waker. Using watercolor paper, tea, acrylic paint, and water-soluble printing ink, I recreate the prologue for the game.

These teams, thousands of them, have only about 2 months to design, build, and test robots to play a brand new game before the competitions begin, and then their work is put to the test! It would be a lot for any professional engineer, but these kids are still in high school! It's pretty incredible.

If you were watching my community posts a month ago, the day that Derek over on Veritasium posted his video about electricity misconceptions, you saw me obsess over that problem a bit too much and immediately use it as the excuse I've been looking for for years to own my own oscilloscope. Instead of two light-seconds of wire, I used about 3 light-microseconds of wire, but it was PLENTY to resolve exactly what is happening in this circuit. I hope you enjoy the analysis!
Thanks to Derek at Veritasium for his blessing to make a real-world version of his gedanken experiment. If you haven't seen his video yet, you might want to go watch that for context, and I also highly recommend ElectroBOOM's video on the topic and EEVBlog's video on the topic. Electroboom's video has some simulated scope traces extremely close to what I saw IRL, and a REALLY fantastic animation (8:27) of him waving an electron around in his hand, shedding magnetic fields as it moves (Even though I ignore magnetic fields in this video - I'm trying to think of a test to find out if they matter).

If you take a histogram of the wait times between geiger tube ticks, you get a beautiful exponential decay curve - most gaps between ticks are extremely fast, and it's rare to go a long time without a tick. You can use this property of random numbers to show that ticks coming from a tube are indeed randomly distributed.
Conveniently, runs of interleaved cards in shuffled decks of cards ALSO follow this exponential decay distribution, with short runs representing short wait times between ticks and very long runs of perfectly interleaved cards being rare, just like long wait times between geiger tube ticks. Because these properties of random numbers are so predictable, you can actually calculate the probability of executing a "perfect" or "Farro" shuffle by accident.

If anybody is curious to try this themselves, this is very much not a sponsored video, but I was using Smooth-On's XTC-3D as my smoothing agent and Angel Guilding's Spray-Silvering chemicals to deposit the silver. if anybody knows more about these products that might explain some of the difficulties I've had, I'd be all ears!

I wrote a program to draw maps of Gerrymandered (or not) congressional districts in the state of North Carolina. I'm not getting into the methods and politics, I just think gerrymandering is a fascinating problem to solve, and the Monte Carlo simulation is great at it! You program in an initial condition, and your "desired election results", and the program handles the rest, adjusting the map pixel-by-pixel until it aligns to your desired metrics (and either a really GOOD map, or a really BAD map).

Episode 3-and-a-half (the final episode) of my series on water ice! In this video I discuss the vapor grown ice crystals with a bit more science, and a lot more timelapses! It's amazing what you can learn aout a physical process when you can photograph it continuously for weeks…

I also introduce the "CTR-Watch-Time Product" as a metric for video success, effectively the additional time YouTube expects to retain a viewer by showing them a thumbnail. It's an interesting metric when youtube is behaving normally, and for videos of similar length.
At the end, I go into some detail on the python script that's actually updating this thumbnail all the time. Warning: it's absolutely horrendous code…

I'm really happy with how all the animations and whatnot came out, and I hope you like my explanation of delay-doppler imaging! I think it's an absolutely fascinating technique that's seen as just too counterintuitive to get a lot of recognition. Delay-Doppler images aren't really "pictures", but they are sure valuable to researchers (and every human living on Earth under threat of asteroid impact!) Share this video with anybody who wants to appreciate how important Arecibo was, and what such an awesome unique instrument was capable of.

Corrections and Clarifications:
- "Plastic deformation" is a term that means a permanent change in shape, even in metals, we call it plastic.
- There are also grain boundary considerations in polycrystalline materials that I don't address at all - mostly it shows up in tension, because bubble rafts aren't ACTUALLY very ductile.
- More to add when I get convinced I'm wrong!

In this video, I use a big scale model to explain how these satellites can be seen from Earth - how they reflect sunlight back towards Earth at night, and how this compares to the previous king of satellite flares, the first-gen Iridium constellation. I also replicate a scale model of the "visorsat" sunshade that will hopefully be effective in blocking the bright reflections from Starlink satellites that have yet to be launched. I also discuss the "twilight effect" that makes rocket launch exhaust plumes so incredible at dusk.
CORRECTIONS:
- the "bottom of space" arrow points to the highest livable altitude. The atmosphere still exists here, but it would imply that Everest climbers have been to space... maybe not accurate... the edge of space is often defined as the Kármán line, but humans would be dead long before getting there.

Welcome to Episode Two of my series about molecular beam epitaxy! In this video, I'm talking about the best way to shoot a beam of atoms at something… As much as that sounds like a crazy scifi weapon, it's actually a great technique for delivering material to a growing crystalline thin film. All materials, even solids, have a vapor pressure and are slowly evaporating. When you put a chunk of material in a vacuum chamber and get it hot, it can evaporate so fast the vapor can be directed towards a target! Let me know in the comments if you have any questions about the MBE I could address in future videos!

This video has been 4 years in the making… In undergrad I started work on a random number generator that used a geiger tube to generate random pulses and a nixie as the primary display (here's the ancient "it almost works" video: youtu.be/dTjmuii5boA). Unfortunately, I couldn't prove it was actually working back then because I couldn't make the geiger tick faster with the test alpha source I had (alpha particles get blocked super-easily). I rebuilt the thing this past summer, and FINALLY got to making the video! I hope you enjoy it!
If you're interested, here's a nice relatively-plain-English summary of the many-worlds-hypothesis (Rick and Morty) and it mentions the competing Copenhagen interpretation (Schrodinger's cat).

In this video I take a trip to Thistle Dhu, the famous putting course at Pinehurst and write a matlab program to simulate a million putts at once, all in an effort to map "Phase Spaces" of golf. There's a common scientific mindset normally referred to as a phase space or parameter space, where you express everything that could happen in an experiment in terms of the variables you can control. In the case of putting a golf ball, the ball can go in the hole, or it can miss completely - if it misses, we also care how far from the hole it stopped. You only actually have control of two variables while putting a golf ball, the initial speed and initial direction. After you hit the ball, physics takes over!
By popular request, here's some code!
