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 Feynman, The 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.)
Its not what you know. Its what you can prove.
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.
When you are a kid you think things will change but 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. Little criminals grow up to be big criminals. 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.
There is no ideal job. After about 6 months every job just becomes work. The ideal job is any 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 (if not the universe) is run by the mafia (especially autistics). Be careful who you piss off. And some people are very very easily pissed off.
Some people prefer to live like animals. You cant change them and you shouldnt try. Let people be what they are.
People arent the problem. Politicians are the problem.
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 entirely conducive to life.
Mythology
