True neutral:  I serve the realm. Someone must.
Your defenses must be as flexible and inventive as the arts you seek to undo
If you do not study, you shall not pass!
It's my job to think as dark wizards do. When it comes to the dark arts I believe in a practical approach. You need to know what you're up against.

Things should be made as simple as possible, but not simpler

Much to learn, you still have
Never bring words to a number fight
Complex problems have simple, easy to understand, wrong answers

Earth. Not my problem.
Do you really believe that just because you downloaded a kung fu program that you can do kung fu?
I have seen memes come and go so fast that they can hardly be said to have occured at all

Would you care to explain your logic?
One does not simply pass without studying
Helmholtz: I have no satisfaction in formulas unless I feel their arithmetical magnitude
The Scotch must flow!

General Curtis LeMay: Flying fighters is fun. Flying bombers is important.
Playing violin is fun. Playing viola is important.
I like to think of it as the "Prime Suggestion"
An orchestra is only as strong as its last viola

Order of magnitude material on the web

Once upon a time, Professors Peter Goldreich and Sterl Phinney pioneered an order-of-magnitude physics class at Caltech.

"The art of insight in science and engineering", Sanjoy Mahajan
"Street-fighting mathematics, the art of educated guessing and opportunistic problem solving", Sanjoy Mahajan
"Order-of-magnitude physics: understanding the world with dimensional analysis, educated guesswork, and white lies", Peter Goldreich, Sanjoy Mahajan, and Sterl Phinney
"Order-of-magnitude physics", Jay Maron
"The solar system", Eric Blackman
"Astropedia", Chris Impey
"The astronomical reach of fundamental physics", Adam Burrows and Jeremiah Ostriker
David Hogg, "Real-world physics: a dropped bucket"
David Hogg, "Air resistance"
Sanjoy Mahanan and David Hogg, "Introductory physics, the new scholasticism"
Sterl Phinney, Caltech
Eugene Chiang, Berkeley
Nir Shaviv, Hebrew University of Jerusalem

Helmholtz: "I have no satisfaction in formulas unless I feel their numerical magnitude."

The Bach chaconne for viola

Shaolin abbott: What is the highest technique you hope to achieve?
Bruce Lee: To have no technique.

Neil deGrasse Tyson (tweet): Kf you seek only easy problems to solve, then ultimately, there'll be nothing about you to distinguish yourself from others.

Richard Askey (mathematician): If things are nice there is probably a good reason why they are nice: and if you do not know at least one reason for this good fortune, then you still have work to do.
