Feynman is an engineer's physicist, and we're on an engineering board afaict
That doesn’t make sense. Every physicist is an engineer and vice versa

And mind the bananas.
Or wood. Or basically most things. Just depends on the level you’re comfortable with.

I have not read it. The black swan was interesting. But in the end I may have liked books from Mandelbrot more. I have met professional traders that did not know (and became very angry) when told that far out of the money options are underpriced because it is not a random walk but a fat tail distribution.
I have not read Thinking Fast and Slow ether but really disliked "The tipping point" by Malcolm Gladwell.
Most impressive book: Thus spoke Zarathustra.
So called fat tailed distributions are a random walk. It’s just that their sample distribution is a power law (no mean hence fat tail). Example of which is a Lévy flight: a random walk with a heavy tail.
Here’s a link for your perusal: https://en.wikipedia.org/wiki/L%C3%A9vy_flight

How is entropy defined in this context?
Clearly there is human-derived input in the system (otherwise... What's the point just crop randomly)
Randomness in pixel values
Speaking of California. SF bay area has a 20% probability of 7.5 earthquake within the next 30 years[1]. Probably not a great place to build stuff either.

You can build earthquake proof buildings. See many nations in the pacific: notably Japan.

What I find fascinating about this is that there are various species which have tackled human speech with at least some success (both actively and passively), while, conversely, we are apparently rather bad at participating in their communicative acts (like, imitating utterances in a meaningful way). Is it just for a lack of interest on our side, or are we lacking something else?
Edit, regarding "something else": Apparently, we are able to recognize individuals of other primate species by face at a very early age, but lose this ability soon (even before we acquire speech), probably in favor of other social abilities. Which may be an indication for a high degree of intraspecies specialication regarding our communicative abilities.
I’m sure any skilled hunter would argue differently. Just watch Meat Eater on YouTube for use of animal sound mimicary ant it’s use in hunting.

How was he "caught" if thats the term?
By the mere fact that the car wasn’t pitting as often. Car was likely inspected afterwards.

Question: Since mass exerts gravitation force, wouldn’t it mean that any mass of any size shape would do that? Just because we don’t have a scientific experiment to measure gravitational forces at small scales doesn’t mean they don’t exist mathematically right? What am I missing when they say quantum particles do not fit with gravity.
Yep any size particle should. But gravity is described by classical physics through general relativity. When you have situations of very small quantum scales and large gravitational fields both general relativity and quantum field theory don’t work well together. This is a big problem in physics.
