My colleague has just made a fantastic set of video tutorials for the SL Applications syllabus. So far he’s made over 60 videos – with more to come! I really like the on screen use of the GDC and clear examples given. Very useful for Applications students. Playlist 1 (Number and Algebra) Playlist 2 (Functions) […]
Spotting fake data with Benford’s Law In the current digital age it’s never been easier to fake data – and so it’s never been more important to have tools to detect data that has been faked. Benford’s Law is an extremely useful way of testing data – because when people fake data they tend to […]
Weaving a Spider Web II: Catching mosquitoes First I thought I would have another go at making a spider web pattern – this time using Geogebra. I’m going to use polar coordinates and the idea of complex numbers to help this time. Parametrically I will define my dots on my web by: Here r will […]
Weaving a Spider Web I often see some beautiful spider webs near my house, similar to the one pictured above (picture from here). They clearly have some sort of mathematical structure, so I decided to have a quick go at creating my own. Looking at the picture above there are 2 main parts, an inner […]
Elliptical Curve Cryptography Elliptical curves are a very important new area of mathematics which have been greatly explored over the past few decades. They have shown tremendous potential as a tool for solving complicated number problems and also for use in cryptography. Andrew Wiles, who solved one of the most famous maths problems of the […]
Prime Spirals – Patterns in Primes One of the fundamental goals of pure mathematicians is gaining a deeper understanding of the distribution of prime numbers – hence why the Riemann Hypothesis is one of the great unsolved problems in number theory and has a $1 million prize for anyone who can solve it. Prime numbers […]
