If you don't pass through anything in life, you can't be anything.
A good proof is one that makes us wiser.
Most likely, logic is capable of justifying mathematics to no greater extent than biology is capable of justifying life.
The goal of a definition is to introduce a mathematical object. The goal of a theorem is to state some of its properties, or interrelations between various objects. The goal of a proof is to make such a statement convincing by presenting a reasoning subdivided into small steps each of which is justified as an "elementary" convincing argument.
What binds us to space-time is our rest mass, which prevents us from flying at the speed of light, when time stops and space loses meaning. In a world of light there are neither points nor moments of time; beings woven from light would live "nowhere" and "nowhen"; only poetry and mathematics are capable of speaking meaningfully about such things.
A proof only becomes a proof after the social act of "accepting it as a proof".
Of the properties of mathematics, as a language, the most peculiar one is that by playing formal games with an input mathematical text, one can get an output text which seemingly carries new knowledge. The basic examples are furnished by scientific or technological calculations: general laws plus initial conditions produce predictions, often only after time-consuming and computer-aided work. One can say that the input contains an implicit knowledge which is thereby made explicit.
I always tell people, 'Everything you’ve heard about Alice Cooper , you can believe maybe 40 percent of it. Everything you’ve ever heard about Keith Moon is true - and you’ve only heard 10 percent of it. '
I am what I am,' Salander said 'I ran away from everything and everybody. I should have said goodbye.
Cultures are virtual realities made of language.
As soon as you feel too old to do a thing, do it.
