In this post we’re going to start a new series in exploring the four fundamental forces, which is how all stuff interacts with itself and everything else [source]. The four fundamental forces of physics are: Strong Weak Gravitation Electromagnetism Gravity…

This post is based on our AI series, which you can find here: Artificial Intelligence – Bayes Network Artificial Intelligence – Machine Learning from Supervised learning Bayes’ Rule and the Monty Hall Problem Artificial Intelligence – Supervised Learning in Python…
History of Optics Around 500-300 BC in the early Greeks, important figures such as Democritus believed that the reason our eyes could see was because our eyes emitted light, or simulacra as he called it, and once it hit a…
Ever wonder how this is possible? You’ve seen it in major sports around the world, from soccer to baseball, the deadly curveball. It’s pretty obvious just looking at it that it has something to do with spin, but how does…
In 1943, Admiral Isoroku Yamamoto, the greatest military commander of the Japanese navy, went to visit one of the front line bases to boost morale. The plan of his visit was communicated through an encoded message through the Japanese Naval…
In our last post on supervised learning, we investigated how an agent could make a function f(x) = y, to train itself to best fit your data. Let’s see how we do this in python, and start with an easier…
If you’ve gone to engineering school or seen too much of “The Big Bang Theory”, you’ve probably heard someone say, with a semi-smug voice: “light isn’t a particle or a wave, it’s both”. After they’re done patting themselves on the…
Previously published AI-related blog posts: Artificial Intelligence – Bayes Network Artificial Intelligence – Machine Learning from Supervised learning Earlier in our AI blog series we have covered topics that have been quite comprehensive and theoretical, so it’s time we show…
Disclaimer: Be aware that this topic is more theoretical than most of our other blog posts. After all this is NOT an easy subject to comprehend. But hang in there, because this will be an important building block before we…
This post will be the first in a series on Artificial Intelligence (AI), where we will investigate the theory behind AI and incorporate some practical examples. The first, and perhaps most important section of this series, will be on probability,…
In the previous section on laser 101, we looked at how a laser works on an atomic scale. We discussed key concepts such as the important correlation between frequency, wavelength and energy. A quick recap is that energy is proportional…

Note: this text is meant as a simplification of laser physics. Laser, or Light Amplification by Stimulated Emission of Radiation (If we want to get technical about it), is a device that emits Light through an Amplification based on Stimulated…
In this blog post we’ll first briefly discuss Fourier Transform and FFT. Then we’ll show you one way to implement FFT on an Arduino. Fast Fourier Transform (aka. FFT) is an algorithm that computes Discrete Fourier Transform (DFT). We’re not…
