The Sound of Freezing: Explained!
For the last few months I've been experimenting with ways to grow ice crystals, and while there's a lot to come on that front (Subscribe for the rest!), welcome to Episode 1: The Sound of Freezing! The vacuum-evaporation setup I used to freeze water in this video was one of the first I tried, and it wasn't until recently I realized that I had inadvertently recorded the SOUND of freezing water - I didn't think it was possible (and I thought freezing water wouldn't make a sound). In this video I explain dendritic growth of crystals, freezing water ice from supercooled liquid, and propose a source for the crackling noise that seems to accompany the formation of ice crystals! Enjoy!

I'm working on a random number generator based on background radiation (True quantum-random numbers). This is the circuit working for the first time. Radiation is passing through a Geiger-Muller tube, stopping a counter and displaying the result on a Nixie Tube.

This is my incarnation of Wilhelm - and he does nothing but scream when he falls. This robot has an accelerometer it uses to detect when it's falling, and a re-recordable audio chip to yell when he hits the ground.

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: https://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).

This is a sequel to my last "ink tube" video, but this time I explain the title of the project, "the entropy of mixing". Entropy is a super weird topic, so I hope this makes sense, and I hope you enjoy!

PUTTI
putting-through-phase-space-thinking
Extra note: I'm starting a Facebook page for AlphaPhoenix with video updates and info about projects I'm working on! https://www.facebook.com/AlphaPhoenixChannel
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!

I BOU
i-bought-1000-meters-of-wire-to-settle-a
I constructed the Veritasium electricity thought experiment in real life to test the result.
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!

AN IN
an-intuitive-approach-for-understanding
In this video, I try to explain electricity Ohm's Law… using a LOT of different demonstrations and analogies. I've been working on this script for like a year and a half now - this took SO long to assemble because electricity is an absolute pain to learn and to explain. I crammed every analogy to describe electricity I could think of into this video (which is why it's... oof... 40 minutes... who's going to watch this?).
When I learn something hard, it's normally after I've seen it a few times before, so with a tough topic in this video, I'm trying to scatter-shot and hope that at least one demo clicks for everybody! If it DOESN'T click for you, let me know what's weird! There will be an FAQ about this video posted on the second channel in a few weeks. If you want to ask a question, drop it in the comments here, or if you want to make sure I see it, leave a note on the new Patreon Discord server!
The biggest intentional omission in this video is not addressing radial charge distribution in a wire, and I know that's going to annoy some of the commenters here. I only talk about 1D wires so I don't have to confuse people by making them imagine different families of electrons at different parts of the wire when at the end of the day they can all get squished and move the same way - so please consider all of my diagrams with electrons getting "more concentrated" to be looking all the way through a wire, including the surfaces :)
