What happens when logic goes wrong? Let’s see why the Law of the Excluded Middle is wrong (sometimes), discover foundational problems at the heart of Mathematics, before finally trying to resolve what’s going wrong. You’ll also learn how to make sense of the negative root of -1, delve briefly into analysis, as well as proving […]
Computational neuroscience, broadly defined, is the mathematical and physical modeling of neural processes at a chosen scale, from molecular and cellular to systems, for the purpose of understanding how the brain represents and processes information. The ultimate objective is to provide an understanding of how an organism takes in sensory information, how information is integrated […]

Most people may think that mathematics is about doing hard sums with large numbers. Whilst it is true that you can do seriously hard computations all day long (try computing the integral of the square root of tan), the majority of mathematics is based on proofs. Here I will outline some of the most common […]
Open Problem “Mathematics may not be ready for such problems.” The Collatz Conjecture was posed in 1937 by Lothar Collatz, two years after he received his Ph.D. It remains open to this day. “Mathematics may not be ready for such problems.” — Paul Erdős. “This is an extraordinarily difficult problem, completely out of reach of present day […]
I was recently listening to a podcast that was recommended to me, and during one episode which discussed big-O theory, the Monty Hall problem was mentioned. The commentators talked a little about it, at which point they admitted to not ‘getting it’ and moved on. This motivated me to share my understanding of the problem […]
If you have an elementary knowledge of physics, it is very possible that you are unsatisfied about the metaphoric explanations of the role of the Higgs boson in “giving mass to other particles”. On the other hand we do not explain gravity and electromagnetism in a similar way. We teach them using mathematical equations, whose […]

Imagine a square of paper lying flat on your desk. I ask you to close your eyes. You hear the paper shift. When you open your eyes the paper doesn’t appear to have changed. What could I have done to it while you weren’t looking? It’s obvious that I haven’t rotated the paper by 30 […]
The American theoretical physicist Richard Feynman is one of the best-known scientists in the world (see this link). Feynman made several contributions to theoretical physics. These include: a new formulation of quantum mechanics using path integrals, the theory of quantum electrodynamics (including the development of his famous pictorial representations known as Feynman diagrams), his contributions to the explanation of the phenomenon of superfluidity of […]
Solving the Basel problem, using an elementary introduction to Fourier series! Part 0: Motivation, some History, and Welcome! Hello and welcome! We are going to be tackling a beautiful problem, the ‘Basel Problem’. It was posed in 1650 by Pietro Mengoli, and it took 84 years to solve it, when the brilliant Euler did so. Euler’s proof was brilliant, but also not […]
I recently started doing some work on audio files and signal processing most of what relies upon the Fourier Series. Now if you’ve taken a Calculus course you’d probably dealt with this. But I think people don’t appreciate Fourier Transform as much it is capable of, although this post will get you started in the […]
