# Categorifying Fundamental Physics

A fundamental fact about quantum theory is that these operators fail to commute: aa* – a*a = 1 in units where Planck’s constant is 1. Remarkably, this fact has a simple combinatorial interpretation: there is one more way to add an element to a finite set and then remove one, than to remove one and then add one.

# 6.5 Teach

.

You cannot teach a man anything, you can only help him to find it for himself.

— Galileo

.

To be catalyst is the ambition most appropriate for those who see the world as being in constant change, and who, without thinking that they can control it, wish to influence its direction.

— Theodore Zeldin

.

The best doctors found a middle position where the were neither over-whelmed by their feelings nor estranged from them. That was the most difficult position of all, and the precise balanceneither too detached nor too caring – was something few learned.

— Michael Crichton

6.4.0 Create = teach or write or both

6.4.1 Create: Teach

6.4.2 Create: Write

.

The basic theme is that whenever you cannot understand something, you should try to create that thing.

How to create?

Write. Write as if you are explaining the materials to someone else.

As physicist Gerar’td Hooft advised, when reading a physics textbook “… imagine how you would write those texts in a smarter way.”

Why is that you can understand a thing when you re-write your textbook?

It is because whenever you write, you have to translate the materials into your own language.

You are CREATING your OWN knowledge.

6.3.2 Quantum Mechanics | 量子力學

.

When physicist Feynman was a student,
there were two versions of Quantum Mechanics.
They described the same thing
but in different mathematical languages.

One version was Heisenberg’s Matrix Mechanics (矩陣力學) , using matrices. Another was Schrodinger’s Wave Mechanics (波動力學), using differential equations.

Feynman could understand neither of them.
So he spent 8 years to create
his own version of quantum mechancis
in order to understand quantum mechanics [1].

Feynman’s version of quantum mechanics is now called
Feynman path-intergral. (路徑積分)

After Feynman’s death, [2] people found that Feynman had written some words on the left-hand top corner of his blackboard:

.

“What I cannot create, I do not understand.”

[2] “I’d hate to die twice. It’s so boring.” — Feynman’s last words

# Recursion

.

4.20 Life as a recursion

Arthur Schopenhauer answered: “What is the meaning of life?” by determining that one’s life reflects one’s will, and that the will (life) is an aimless, irrational, and painful drive. Salvation, deliverance, and escape from suffering are in aesthetic contemplation, sympathy for others, and asceticism.

# Act on Fear

4.18 Dale

.

Inaction breeds doubt and fear. Action breeds confidence and courage. If you want to conquer fear, do not sit home and think about it. Go out and get busy. — Dale Carnegie

It was a high counsel that I once heard given to a young person, “Always do what you afraid to do.” — Emerson

The way to develop self-confidence, he said, is to do the thing you fear to do and get a record of successful experiences behind you. — Lowell Thomas

# 親歷其境

4.17.4 Influence

.

When suggesting on how to write a successful book, John T. Reed wrote:

“At the Dale Carnegie public speaking class, which I highly recommend — they say anyone can make a good speech if he or she has earned the right to speak on the subject in question. How do you earn the right? By living through the subject or by doing extensive research on it — which is arguably another form of living through it. Same principle applies to how-to writing.”

The difference between theory and practice is small in theory but big in practice.

— Me, based on an existing quotation

The principle of science, the definition, almost, is the following: The test of all knowledge is experiment. Experiment is the sole judge of scientific “truth.”

— Richard P. Feynman (The Feynman Lectures on Physics, 1963)

4.16 Impossible

.

If you want to imagine what the world is going to be like in the future,

don’t work for what’s possible now.

Start by imagining the impossible,

only then we even get close to a vision of our fantastic future.

— Gillian Anderson, Future Fantasic

To be creative, think not what is possible, but what is impossible.

# “Why not?”

4.15 Shaw

1. You see things as they are and ask, “Why?” I dream things as they never were and ask, “Why not?” — George Bernard Shaw, Back to Methuselah (1921)

2. Reasonable people adapt themselves to the envirnoment; unreasonable adapt envirnoment to themseleves. Therefore, all human progress are made by unreasonable people. — George Bernard Shaw, Maxims for Revolutionists (1903)

3. Do not follow where the path may lead. Go instead where there is no path and leave a trail. — Muriel Strode ( ? )
