Bertrand Russell Quotes

And what are these fluxions? The velocities of evanescent increments. And what are these same evanescent increments? They are neither finite quantities, nor quantities infinitely small, nor yet nothing. May we not call them the ghosts of departed quantities...?

In my free time I do differential and integral calculus.

If a nonnegative quantity was so small that it is smaller than any given one, then it certainly could not be anything but zero. To those who ask what the infinitely small quantity in mathematics is, we answer that it is actually zero. Hence there are not so many mysteries hidden in this concept as they are usually believed to be. These supposed mysteries have rendered the calculus of the infinitely small quite suspect to many people. Those doubts that remain we shall thoroughly remove in the following pages, where we shall explain this calculus.

I’m so tired... I was up all night trying to round off infinity.

Every one who understands the subject will agree that even the basis on which the scientific explanation of nature rests is intelligible only to those who have learned at least the elements of the differential and integral calculus, as well as analytical geometry.

Mathematical Analysis is... the true rational basis of the whole system of our positive knowledge.

Nonmathematical people sometimes ask me, “You know math, huh? Tell me something I’ve always wondered, What is infinity divided by infinity?” I can only reply, “The words you just uttered do not make sense. That was not a mathematical sentence. You spoke of ‘infinity’ as if it were a number. It’s not. You may as well ask, 'What is truth divided by beauty?’ I have no clue. I only know how to divide numbers. ‘Infinity,’ ‘truth,’ ‘beauty’—those are not numbers.

Mathematics is the gate and key to science.

Math - it's not my best subject.

Math is sometimes called the science of patterns.

I read one or two other books which gave me a background in mathematics other than logic.

I was a mathematics major and really into math.

I turn aside with a shudder of horror from this lamentable plague of functions which have no derivatives.

I love math.

Math is one of my favorite subjects.

Mathematicians are fairly cheap.

Math was always my best subject growing up.

Mathematics - the unshaken Foundation of Sciences, and the plentiful Fountain of Advantage to human affairs.

There are infinite numbers between 0 and 1.

I protest against the use of infinite magnitude ..., which is never permissible in mathematics.

Calculus is the outcome of a dramatic intellectual struggle which has lasted for twenty-five hundred years.

I was very into math and calculus, and just always was very - really interested in that. But any sort of numbers.

There must be some limit to the thing. It cannot go on to infinity.

If the infinite had no me, then me would be its limit. It would not be the infinite, therefore it would not be.

Math was my big interest when I was in prep school. I was considering taking math in college, and majoring in it.
