Let’s admit it, most of us are intellectually lazy, and thinking is a strange and hard activity, because it requires effort. Even philosophy, the prime discipline devoted to thinking, mostly circulates the ideas of other people, and has some similarity to journalism. Real thinking is hard, and I will always respect Kant for the simple advice he gave to […]

Read More...If you add up all the natural numbers from 1 to infinity, you should get a really large version of infinity, but this is not the case. What you get is minus one/twelfth. Watch the following well-made video clip in order to understand how this happens. Related posts: Fundamental Theorem of Arithmetic Nature by Numbers […]

Read More...Here are two computer-animated videos from Youtube that demonstrate some properties of knots, the relations between knots and space, and how we arrive at hyperbolic space. Easy to watch, and very informative. Part Two: Related posts: Klein Bottle Tesseracts: from 3 to 4 Dimensions. 0 to 6 dimensions and back – simple rotation. […]

I would like to attempt here to describe, in terms of philosophical concepts, the development of foundational research in mathematics since around the turn of the century, and to fit it into a general schema of possible […]

Read More...Below there is an interesting video inspired by numbers, geometry and nature, created by Cristóbal Vila. Nature looks complex, but the underlying principles are simple, for instance the Fibonacci Series of numbers. The natural beauty and complexity we see all around us is deeply astonishing, but what’s even more astonishing is all the math behind […]

Read More...How does mathematics and reality relate to each other? Some mathematicians believe that mathematical entities are “real”, and this view can be characterized as a version of Platonic philosophy. Quine and Putnam developed an argument in support of mathematical realism, which starts with the observation that mathematics is indispensable for almost every other science. Here […]
