Falsifiability is King

Note: philosophy and science used to be considered about the same thing in Newton's time.

The Big Giant Piano

Ever since I was a baby, my grandparents had a baby grand piano sitting in the corner of their living room. While I was growing up, I used to noodle around on it from time to time. One thing I noticed was that the middle of the keyboard sounded very musical, but the bottom octave basically just growled. It was hard to tell which note was being played. Each note sounded different, but the actual pitch was indistinct. 

It wasn't a bad piano. It's just that the bass strings were too short to sound the fundamental very well. And uprights and spinets, well, forget about it. The problem is made worse by the fact that the hammers hit the strings close to the bridge, which tends to excite more harmonics than fundamentals. 

Even concert grands lack really clear fundamental bass notes. It's basic physics, captain. 

When I was in high school, I learned to play 'Joy to the World' by Three Dog Night on our family's little Wurlitzer Spinet. I didn't think anything of it, until one Christmas, I was at my Great Uncle's house, and he had a concert grand in his living room. (He was a session musician in Hollywood, so of course he did!) I sat down at that piano, and started pounding out JTW by TDN. I was blown away by how good it sounded on that piano. For $40,000.00 in 1960s dollars, it better sound good!

Well, here's a piano that would put that tinkle box to shame! Fundamental bass, baby! It's all about that bass.


Oh and JTW by TDN, yeah. This is how boy bands sounded when I was a teenager...

I'm Just Putting This Here for Reference

Whenever I need a short refresher on the fundamental particles of the standard model, I always have to track down this video. Now I'll have it until it scrolls off my backlog.



One of the Best Explanations and Demonstrations of the Double Slit Experiment

His description of superposition and the 'wave function collapse' finally explained in a way that doesn't defy reason. The wave function is a prediction, and a prediction is pointless after the fact. It doesn't mean physics or reality has changed.

This Will Blow Your Mind. And Then AI Will Read It


Remember George Harrison's song from Yellow Submarine, "It's All Too Much"? Well, this is all too much. I didn't think I would like this, and I still don't, totally. But the technology really is interesting.

Brain and brain! What is brain?
