The problem with g is that it's a number. Who has higher g, Magnus Carlsen or Terence Tao?

Taleb is coming from the quant world. A trader can make or lose a lot of money, and that distribution of returns is fat-tailed, as exemplified by 2008 crisis.

The article gives two definitions of linearity: 1) f(x) is linear if f(x)=(-a2/a1)x-b, and later 2) f(x) is linear if f(x1+x2)=f(x1)+f(x2) But the function f(x)=x+1 is linear according to (1), but not according to (2). And there is no

It's not like I planned that route. Each step in isolation looked reasonable at the time.

It's a lot more difficult to jam short wave than GPS because of multipath propagation. The Soviets routinely jammed Radio Free Europe / Radio Liberty yet it was still possible to listen to it. The navy doesn't have to be on t

Yes. Planned to open a burner when really needed. So far there's been no need to.

There is a relationship between gun control and suicides: http://brady-score.github.io/ Doesn't mean it's causal, maybe there are confounding factors, but the relationship itself does exists. With that said, if pe

But can someone who knows only two or three fields out of so many that exist now be really called generalist?
191.
by pps43 8y ago
In times of Aristotle, Leonardo Da Vinci, and (to a lesser extent) Benjamin Franklin one person could learn a significant portion of total scientific knowledge. That's no longer the case. There could be no more deep generalists.

I don't have 1900+ rating and can follow most of it, although occasionally I need to pause the video to understand why some "obvious" things are indeed obvious. It's true that without some basic knowledge of chess it wou

We do, they just don't qualify for the world championship. If Mikhail Tal was alive today, he would play boring chess, too. Otherwise modern GMs would just accept his sacrifices, not make any mistakes, and win.

Yes, pretty sure. Had to zoom in a lot in audio editor to even see it. Could hear it nevertheless. It's important for the room to be quiet, as the sound is very faint and easily masked, but it's there. It's possible that Blue

16 bits give you 96 dB SNR only if your signal is one-bit. In a quiet room with decent headphones set to comfortable level I can easily hear one-bit flips in otherwise silent WAV file. Not a problem for popular music that's consistentl

Actually the opposite is true. Transistors are approximately linear in half-open state, as in Class A, and non-linear at the extremes (when either fully open or fully closed).

But we already have "next-gen intermediate organizations" that filter the news for us. I carefully curate people I follow on Twitter, subreddits I'm subscribed to on reddit, podcasts in my feed, etc.

Calling a fingerprint "something you are" is a stretch. You are leaving fingerprints everywhere, they can be lifted from any smooth surface you touched (or even high-resolution photo) and then used to open biometric locks.

For some definition of 'better'. I know excellent race drivers who were in rather unfortunate and totally avoidable road accidents.

People in icy and snowy climates are not necessarily better drivers, but usually drive better in ice and snow than people who are rarely exposed to such conditions. It's a skill that can be learned through repetition. They also tend to

Some of public fear is rational. It doesn't take a degree in statistics to figure out that nuclear disasters happen more often than official estimates of their probability imply.

It is possible for the signal to be below the background noise. For example, GPS works this way. Sonars on submarines do the same thing, they send out a noise-like signal that can be detected only if you know what to correlate it with. Ther

The point of spread-spectrum signal is that it's indistinguishable from noise unless you know the key. With frequency-hopping you still have spikes in the spectrum around the frequencies you hop between, but with most modern systems yo

It can pull the steering wheel, but I'm pretty sure the ratios are selected so that I can still overpower it. The steering wheel is still mechanically connected to the front wheels. And it surely can't disable brakes. It can disab

Everything is relative. $1,000 balance is a lot of money for someone making $35,000, not so much for someone making $350,000. Many independent variables that go into risk scores tend to be ratios or averages, hence zero (or near zero) denom
