You can’t just replace a material like that in something as large as a ship. You need to have the right toughness, ductility, fatigue, etc. Steel varies a lot. You can buy a 1000 page book that just lists different steels, along with their

I can think immediately of applications: - bio engineering -- predicting (?) or designing (?) molecules that are large chains to perform some particular function - coverage path planning -- sort of a "roomba" problem -- find a co

We met some guys in San Diego who ran a (definitely illegal) business doing this with scooters. They wanted to sell us one of them for $200 (against market price of $6-700); we declined. Basically, around about 2016 (maybe?) the number of e

Yes, I have a similarly mixed view of Musk. On the one hand, my god what they are doing at SpaceX, Starlink, (and even some parts of) Tesla are incredible! And I suppose without Musk playing carnival barker, these things aren't possibl

I mean, arguably, most of the valuation of his companies are dependent almost entirely on his presence on social media -- Twitter being an essential piece of that. I mean Tesla P/E is like 209. 209!! GM PE is at 6. Where does this trem

A class action which may cost the manufacturer 10s of millions of dollars. Yeah, you only get a small check. Yeah, the lawyers get a lot. But what other remedy does the average consumer have against this type of subtle but abusive behavior.

I think this is less a simile and more a physical reality. What is your arm but a series of sensations and connections in your brain? Your arm is a physical thing; but to the extent that it exists to you, it exists in your brain. So I think

I trust the physical impossibility of tracking cash over the hypothetical enforcement of legislation any day. Why risk it? How many employers have used data on candidate salaries in violation of the law in California? How would we ever know

I would urge you to take a closer look at Elon, Gates, or any other billionaire who pledges to have any goal other than "accumulate more." For example, Elon's personal spending and the structure of his compensation. If he jus

Gravity takes care of the pressures. If you put a long pipe vertically in the water, with its bottom open and its top sticking up a couple meters on top, and then put some water into the top of it, what happens to the water column inside? Y

I only got partway through this. I want to say to the author: Oh my god just stop taking yourself so seriously. Really. You don't need to do this. You're trying waaaay too hard. It's opaque and mysterious and lovecraftian to

Yes, it's quite bizarre. I have used blender to generate training data for a neural network (which was a stunning success, and quite fast compared to any other method I could think of). I had no clue how to use blender before, but now

That still trips me up from time to time. I'm not sure why anyone ever uses percentage increase to communicate anything. Just say the quantity increased "from 0.0015 to 0.002" or something. It's particularly prevalent in

I think there are other effects of increased CO2 concentration that are not well understood and could be catastrophic. Like ocean acidification. That actually scares me far more than the heat aspect.

I found a solution for Firfox on Ubuntu MATE: 1. go to about:config 2. find widget.non-native-theme.scrollbar.size.override 3. Change to some pixel value (I have mine set at 26). voila! I do not understand why the default is so thin. Really

It totally doesn't, which is why it's baffling that (either!) author goes into so much detail about "diversity words." I can put a chart of lexical similarity over a chart of the number of employed airplane mechanics and

the cynical take is: that’s the whole point of the presidency in the first place. Have one guy who is technically in charge of the machine, the machine commits countless crimes, then after 4/8 years you pin all those crimes on the sing

Math is incredibly useful; probably everyone here knows that. But it's actually fine that most people don't use it. What we really need is for every student to realize why math is useful -- so that if they want to, they can go l

The difference, though, is that the proof of work is qualitatively — physically! — a different type of work. The value of money is derived from moving against thermodynamic equilibrium. Cryptocurrency’s value comes from moving towards t

No, you can’t. If you follow the axioms of the cryptocurrency evangelists to their logical ends, transferring cryptocurrency to another wallet is something that happens entirely in virtual space. Of course, this virtual space is coupled w

No, there isn't. Money is useful because it is an abstraction of a physical process somewhere. Cryptocurrency can never be an abstraction of some physical process.† Therefore, I would argue, it can never be useful to us. † Well, tech

I've gotten this feeling, ever since about 2008 or so, that the map that is asset prices is slowly, inexorably becoming uncoupled from the territory of the physical world. This economy-scale decoupling is the dual of each and every one

This article is fantastic. For those who have some familiarity with Python, I found this to be a great resource for Kalman Filtering: https://github.com/rlabbe/Kalman-and-Bayesian-Filters-in-Pyt...
