Welcome to the Tree of Knowledge Wiki!

A collection of concise study guides to make learning as quick and painless as possible. Topics include, but are not limited to, math, physics, biology, and history.

Teachers are trees of knowledge. Fruit is (virtually) free. Will you eat or are you afraid it will bite you?


In a world full of wonders mankind has managed to invent boredom



Disclaimer

The mass of an object never seems to change: a spinning top has the same weight as a still one. So a “law” was invented: mass is constant, independent of speed. That “law” is now found to be incorrect. Mass is found to increase with velocity.

Now, what should we teach first? Should we teach the correct but unfamiliar law with its strange and difficult conceptual ideas? Or should we first teach the simple “constant-mass” law, which is only approximate, but does not involve such difficult ideas?

This point arises again and again in teaching physics. At different times we shall have to resolve it in different ways.

Richard FeynmanThe Feynman Lectures on Physics


As Richard Feynman pointed out we can either strive to impart a strictly accurate but hideously complicated mathematical understanding of physics or we can try to impart an intuitive understanding of physics. It is impossible to do both. We will try to do the latter. Students that prefer the other approach should look elsewhere.

Four value Bayesian logic

Classical logic is a two-valued logic meaning that any proposition is either true or false. But Bayesian logic works differently.

I do not expect
that it is True
I expect
that it is True
I do not expect
that it is false
I dont know True
I expect
that it is False
False I cant know
I do not Believe I Believe
I do not Disbelieve Agnostic Belief
I Disbelieve Disbelief Confusion
I do not Hate I Hate
I do not Love Stranger Enemy
I Love Friend Frenemy


Never believe anything

Sometimes you know that you know

Sometimes you know that you think

But you should never think that you know

You can win every battle and still lose the war

Victorian society: sex is dirty so let's not do it.
Modern society: sex is dirty so let's do it.

In 200 years we haven't learned a single thing. 200 years of rebelling against Victorian prudishness has accomplished exactly nothing.

Liberals rebel against Victorian rules and conservatives embrace them. Neither is right.

Humans vs animals

Objectivity is what separates humans from animals. Animals lack the capacity for objective reasoning. Animals think the universe revolves around their ego.

(Objectivity is not the same thing as responsibility)

Two main "lifestyles

The two main lifestyles are civilian and military which roughly parallels country versus city life.

  • Civilian: Work to live
  • Military: Live to work

The military lifestyle is an obsession with work and money. It is not a way of life. It is a way of death. It is an infectious disease that should be eradicated.

Objective laws

God exists God doesnt exist
Theism Civilization Objective laws exist
Dystheism Atheism Objective laws dont exist


A civilized society is a society whose laws do not favor any one person or any one group of people. The more a society treats everyone as equals the more civilized it is.

Some advice

You should seldom if ever offer negative advice.

There is a solution for every problem and shooting your mouth off is seldom the solution to anything. When things become intolerable just leave quietly without making a scene. Always behave as though you were the uninvited guest because it may well turn out that that is exactly what you are.

Never lend anything that you arent fully prepared to never see again. Never lend to friends.

Hope for the best but prepare for the worst.

People will lie to you with perfectly straight faces for no reason at all.

Smiles mean nothing. (If not less than nothing.)

Obey the rules. Obey the law. They will catch you. Even if you are sure that no one saw you and that there is no way they could know they will catch you.

if you want to know what is going on in the world then just follow the money. It's all about the money.

Things don't change when you get older. The adult world is just as childish and idiotic as the childhood world. Maybe even more so. Adults just hide it better. The world doesnt change. It is you that must change.

If you dont know whats going on or what to do dont just say "well I dont know what to do so I will just do the only thing I know how to do and hope that that is the right thing" because it wont be. If you dont know whats going on then figure out whats going on. If you dont know what to do then figure out what to do. Experiment.

The best things in life are not free. They are very very complicated with no simple easy solution. Very good is very close to very bad.

There is no ideal job. After about 6 months every job just becomes work. The ideal job is a job that is well within your capabilities.

Above all else be happy. Always make your boss and those over you look good. Do NOT EVER make the great "gods" jealous. Dont be a fool. Choose "wisely".

Much of the world is run by the mafia. Be careful who you piss off. And some people are very very easily pissed off.

Honor and nobility are luxuries that only the rich can afford.

if you want people to be comfortable around you then it is not enough to simply be a nice person. One must make a conscious effort to make people feel safe.

Books

The best books are college textbooks. They are expensive but they are far better than what you find at a public library.

Pain

The simplest and easiest way to eliminate pain and suffering in humans and animals is to eliminate, or render inoperative, all pain receptors either through breeding or drugs. Why is nobody talking about this? (Probably because its considered to be a military secret).

Two worlds

The Bizarro World we live in is split between the empirical and the nonempirical. Between the visible and the invisible. Everything that is decent and compassionate and rational (and sexual) belongs to and remains in the invisible part of the world.

One world is all-good and the other is all-bad. But neither world by itself is conducive to life.
