Algumas citações

Eis chegada a hora de um nerd moment aqui no elogio. Não tenho mais nada que fazer e como já vem sendo habitual decidi debitar para aqui pensamentos de outras pessoas que por algum motivo eu acho interessantes.

Sem mais delongas cá vai disto:

The population rises exponentially,
the number of clues rises geometrically,
the number of clueful rises arithmetically.
This is why the world has problems

Charles Babbage:
On two occasions I have been asked, ‘Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?’ I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

Godfrey Harold Hardy
It is not worth an intelligent man’s time to be in the majority. By definition, there are already enough people to do that.

Alan Turing
Science is a differential equation. Religion is a boundary condition. (Esta é capaz de ser a
melhor piada científica que conheço. A sério que é!)

“As far as the laws of mathematics refer to reality, they are not certain, as far as they are certain, they do not refer to reality.” — Einstein

Lord Kelvin
‘When you can measure what you are speaking of and express it in terms of numbers, you know something about it. When you cannot express it in terms of numbers your knowledge of it is of a meagre kind.’

Heinrich Hertz
‘We cannot escape the feeling that these mathematical formulae have an independent existence and an intelligence of their own, that they are wiser than we are, wiser even than their discoverers, that we get more out of them than was originally put into them.’

“Gravitation cannot be held responsible for people falling in love.”

“If only I had the theorems! Then I should find the proofs easily enough.”

Anyone who cannot cope with mathematics is not fully human. At best he is a tolerable subhuman who has learned to wear shoes, bathe, and not make messes in the house. (Adoro o extremismo desta.)

“Math is built with facts as a house is built with bricks, but a collection of facts cannot be called mathematics anymore than a pile of bricks can be called a house.” ~Poincare

The question of whether Machines Can Think … is about as relevant as the question of whether Submarines Can Swim.

Galileo
Philosophy is written in this grand book, the universe, which stands continually open to our gaze. But the book cannot be understood unless one first learns to comprehend the language and read the letters in which it is composed. It is written in the language of mathematics, and its characters are triangles, circles, and other geometric figures without which it is humanly impossible to understand a single word of it.

“He is unworthy of the name of man who is ignorant of the fact that a diagonal of a square is incommensurable with its side.”
Plato (429-347 BC)

“God does not care about our mathematical difficulties. He integrates empirically.” - Einstein

All mathematics is divided into three parts: cryptography (paid for by CIA, KGB and the like), hydrodynamics (supported by manufacturers of atomic submarines) and celestial mechanics (financed by military and other institutions dealing with missiles, such as NASA).

There are 10 kinds of people - those who understand binary notation, and those who don’t.
