"If you think experts are expensive, wait and see what amateurs will cost you."
"You cannot go on 'seeing through' things for ever. The whole point of seeing through something is to see something through it. It is good that the window should be transparent, because the street or garden beyond it is opaque. How if you saw through the garden too? It is no use trying to 'see through' first principles. If you see through everything, then everything is transparent. But a wholly transparent world is an invisible world. To 'see through' all things is the same as not to see."
A simple theory of aesthetics: If the best stuff from then is still better than good stuff from now, it's art. If the best stuff from then is worse than bad stuff from now, it's technology.

We treated science like it’s a weak-link problem where progress depends on the quality of our worst work. But science is a strong-link problem: progress depends on the quality of our best work.

How can Alice communicate all of math to Bob? Mail him some chalk and wait!
Love is not a craving, love is a yearning. ~ Contrapoints.
If Alice uses abstract algebra to solve problem and Bob uses concrete calculation, Alice's result is more generalizable than Bob's, while Bob's method is more generalizable than Alice's. This is one reason why combining the two approaches is so valuable. You can start with something you know will work but may not unlock a great mystery, and then look for patterns that clue you in to a wider story.
"There are two kinds of scientific progress: the methodical experimentation and categorization which gradually extend the boundaries of knowledge, and the revolutionary leap of genius which redefines and transcends those boundaries. Acknowledging our debt to the former, we yearn nonetheless for the latter"

Bott also used to say that a cocyle was "something that hovers over a space and when it sees a cycle, pounces on it and spits out a number".
I'm not complaining here, quite the opposite: this story is really quite exciting and the work mentioned is both real and fascinating. We are essentially back to the days when Newton tried to explain the nature of gravity looking at Kepler's laws trying various options and separating what works from what doesn't. I'm only saying that the famous "physicists' intuition", which is so overrated, is actually just the benevolence of Nature. Why should the Nature be so benevolent to us remains a mystery and I know neither a physicist, nor a mathematician, who could shed any light on that. The best explanation so far is contained in Einstein's words "God is subtle, but not malicious", or, in a slightly less enigmatic form, "Nature conceals her mystery by means of her essential grandeur, not by her cunning".

Knuth says something similar (on his web page I think). He says he doesn't read email because email is good for people who want to stay on top of things but he wants to get to the bottom of things.

A cylinder will roll like a sphere in one direction but not roll like a cube in the other. That doesn't make it a sphere and a cube at the same time. It makes it something different. (in analogy to wave-particle duality)

The manner in which the mathematician works his way towards discovery by shifting his confidence from intuition to computation and back again from computation to intuition, while never releasing his hold on either of the two, represents in miniature the whole range of operations by which articulation disciplines and expands the reasoning powers of man. (Personal Knowledge, 131)
Everyone knows that putting a untrained business major in charge of a squadron of soldiers would end badly. He might be able skate by until they got into combat, maybe, but after that they wouldn’t listen to him for long. But for some reason we think that putting an mba in charge of an engineering team is a good idea.

It is interesting to see where people insist proximity to a subject makes one informed, and where they insist it makes them biased. It is interesting that they think it’s their call to make.

David Marquet's credos from "Turn The Ship Around!". Don't ask "Are we ready?"; instead, ask "How ready are we?". Everything needs to be phrased so as to invite people to express the knowledge they have, rather than demanding what amounts to a declaration of tribal identity.
You can't just go around recognizing what people don't understand. That's what got Socrates killed. You've gotta make them understand what they don't understand without making them want to kill you. That's what makes a great teacher / leader / etc.

“The math students dropped out because they could not understand anything.

When people thought the earth was flat, they were wrong. When people thought the earth was spherical, they were wrong. But if you think that thinking the earth is spherical is just as wrong as thinking the earth is flat, then your view is wronger than both of them put together.

She told me that I was what she calls institutionally poor. That I had been conditioned thru my childhood to think like a poor person and in doing so you send out unconscious signals to others. She told me this because she came up similar. She told me that it causes you to over analyze and over estimate risk and therefore you will not take the bold moves that people that don't have to worry do. That while you can change the world and everyone see it. If you hold onto the fear on meeting your net under you, that you will never extract your true value from other. So I said, so you are going to pay me my fair value, she laughed and said no, I got you for a very good deal. 3 Days latter I walked into her office, with my resignation letter and told her I had an offer from another company. She said, now you get it, how much did they offer. I told her, and she said I will double that if you stay.
Here's a discontinuity irl that I read about: you bite into an apple and find a worm. Disgusting. But worse would be to find 1/2 a worm, worse still 1/4 of a worm, etc... continuity would imply the worst case scenario is biting into an apple and not finding a worm.
Mona Lisa was special in part because it was uncommon for people to smile. In Middle Ages, someone smiling a lot would be perceived as stupid. That's why facial expressions in medieval imagery are so serious. Today, being surprised a lot is often taken as a sign of stupidity, whereas in ancient Greece an owl was the bird of Athena, the goddess of wisdom. Because, obviously, an owl is always surprised, and surprise is the first step to understanding.
Social justice and "fairness" is rarely one of the main goals of a meritocracy. The main goal of a meritocracy is peak performance. NFL teams select the "best" quarter-backs not because it's most fair, but because it will produce the most wins. Universities grant tenure to the most productive professors, because that will enhance the University's reputation. Hospitals hire the best doctors, because they can save the most lives. A society should delegate its most important responsibilities to its smartest/most-knowledgable members, because they can best lead society through worldly challenges.
Which is not to say that Social Justice isn't important. It is vital. But you don't get to it by hiring the wrong people in the wrong roles. A meritocracy excels at producing wealth - Universal Basic Income, Universal Healthcare, Unemployment Insurance, better Public Schooling... these are the kind of Social Justice programs that best distribute the wealth back to society.
Some kids grow up on football. I grew up on public speaking (as behavioral therapy for a speech impediment, actually). If you want to get radically better in a hurry: 1) If you ever find yourself buffering on output, rather than making hesitation noises, just pause. People will read that as considered deliberation and intelligence. It's outrageously more effective than the equivalent amount of emm, aww, like, etc. Practice saying nothing. Nothing is often the best possible thing to say. (A great time to say nothing: during applause or laughter.) 2) People remember voice a heck of a lot more than they remember content. Not vocal voice, but your authorial voice, the sort of thing English teachers teach you to detect in written documents. After you have found a voice which works for you and your typical audiences, you can exploit it to the hilt. I have basically one way to start speeches: with a self-deprecating joke. It almost always gets a laugh out of the crowd, and I can't be nervous when people are laughing with me, so that helps break the ice and warm us into the main topic. 3) Posture hacks: if you're addressing any group of people larger than a dinner table, pick three people in the left, middle, and right of the crowd. Those three people are your new best friends, who have come to hear you talk but for some strange reason are surrounded by great masses of mammals who are uninvolved in the speech. Funny that. Rotate eye contact over your three best friends as you talk, at whatever a natural pace would be for you. (If you don't know what a natural pace is, two sentences or so works for me to a first approximation.) Everyone in the audience -- both your friends and the uninvolved mammals -- will perceive that you are looking directly at them for enough of the speech to feel flattered but not quite enough to feel creepy. 4) Podiums were invented by some sadist who hates introverts. Don't give him the satisfaction. Speak from a vantage point where the crowd can see your entire body. 5) Hands: pockets, no, pens, no, fidgeting, no. Gestures, yes. If you don't have enough gross motor control to talk and gesture at the same time (no joke, this was once a problem for me) then having them in a neutral position in front of your body works well. 6) Many people have different thoughts on the level of preparation or memorization which is required. In general, having strong control of the narrative structure of your speech without being wedded to the exact ordering of sentences is a good balance for most people. (The fact that you're coming to the conclusion shouldn't surprise you.) 7) If you remember nothing else on microtactical phrasing when you're up there, remember that most people do not naturally include enough transition words when speaking informally, which tends to make speeches loose narrative cohesion. Throw in a few more than you would ordinarily think to do.
Siddharth, you said you're wired that way, and thus can't believe in religion. So you can't change yourself; thus, you're pure. Therefore, all you need is a monad ) to change the immutable into the mutable --- thus, embrace the Leibniz.
