sagansense: In Mysterious Pattern, Math and Nature Converge image 1: In Cuernavaca, Mexico, a “spy” network makes the decentralized bus system more efficient. As a consequence, the departure times of buses exhibit a ubiquitous pattern known as “universality.” (Photo: Marco de Leija) image 2: The red pattern exhibits a precise balance of randomness and regularity known as “universality,” which has been observed in the spectra of many complex, correlated systems. In this spectrum, […]

Once again, here are the multiple-choice problems with explanations for today's New York State Geometry Regents exam. Since I typed this up as quickly as I could, there are no images, graphs or diagrams included. I'll edit them as I am able to. A common theme: there were several questions involving the equation of a circle, as there always are, as well as several questions which not only involved the Pythagorean Theorem, but very specifically a 3-4-5 triangle or a multiple of it.

(Click on the comic if you can't see the full image.) (C)Copyright 2015, C. Burke.Fun fact: if I didn't post this today, I'd have to wait two more months to use it. By tradition, "30" also means the end of a news story even though more months end in 31 days. That's because it has nothing to do with the end of the month and more to do with the letters XXX, which is 30 in Roman numerals. Not that there's any hidden meaning here. This is not the end of anything. ... except for these notes, of […]

fouriestseries: Wave Equation The wave equation is a partial differential equation that describes the propagation of various types of waves. The equation appears throughout many fields in physics, including acoustics, fluid dynamics, electromagnetism, and quantum mechanics. With some modifications, it can even describe the spread of traffic jams on busy highways! The one-dimensional equation was first discovered by d’Alembert in 1746 as he studied how vibrations propagated through a […]

The Pythagorean Theorem is possibly the first (and in my opinion, only) piece of beautiful maths in GCSE. Not only is it a majestic piece of mathematical wonder, it carries with it great history, real-life application, visual beauty and it … Continue reading →
