@Logically_JC Kid Rock?

I can’t believe this guy is running our military.

I have never done anything 'useful'. No discovery of mine has made, or is likely to make, directly or indirectly, for good or ill, the least difference to the amenity of the world. G.H. Hardy — A Mathematician's Apology

Newton spent more time writing about alchemy and theology than about physics or mathematics.

You think you know what belief is? No! At best you have an accidentally true opinion, unless you've read @jontweetshere's and my edited collection, The Nature of Belief, hot off the press at OUP. (Also available open access at OUP's website.)

We’ve combined Women & Gender Studies, LatinX Studies, African-American and African Diasporic Studies, Middle Eastern Studies, Asian Studies and Judaic Studies into one department. We’re calling is ‘Sociology.’ Take that Board of Regents! Take that state legislature!

We just want affordable gas and groceries.

subserves is to bring a skeleton representation of the relations concerned in the problem before the mind’s eye in a schematic shape, which can be studied much as a geometrical figure is studied. /2x

What really distinguishes mathematics, according to him, is not the subject of which it treats, but its method, which consists in studying constructions, or diagrams. That such is its method is unquestionably correct; for, even in algebra, the great purpose which the symbolism /1

Kant, in the Critique of pure reason (Methodology, chapter I, section I), distinctly rejects the definition of mathematics as the science of quantity.

Americans love their Canadian brothers and sisters. They are the greatest allies, friends, and neighbors any country could have. So proud of Buffalo Sabres fans. 🇺🇸🇨🇦 #canada #sabres

You know what the solution to $4.23/gal gas is, right? A BALLROOM!

step upon the holy ground with reverential awe, and advance almost with timidity, fearful, as the signs of Deity break upon them, lest they be brought face to face with the Almighty.” —B. Peirce /4x
