Optics 101
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…
The Magnus Effect
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…
Introduction to Quantum Cryptography
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…
Artificial Intelligence – Supervised Learning in Python
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…
Introduction to Quantum Mechanics: Particle or Wave?
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…
Bayes’ Rule and the Monty Hall Problem
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…
Artificial Intelligence – Machine Learning from Supervised learning
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…
Artificial Intelligence – Bayes Network
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,…
Laser 101 – pt. 2: Terahertz
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…
Electronics 101 pt. 4: RL and RC Circuits
Previous posts in this series: Electronics 101: Voltage, Current and Resistance Electronics 101 pt. 2: Kirchhoff’s Laws Electronics 101 pt. 3: Applying the Laws If you’re unsure about how capacitors and/or inductors work, check out: An Intro to Capacitors An…
Laser 101 – pt. 1: The Basics
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…
What Is FFT and How Can You Implement It on an Arduino?
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…
Electronics 101 pt. 3: Applying the Laws
Earlier we have written blog posts about both Ohm’s Law and Kirchhoff’s Laws. It’s time to put these in action combined to analyze simple DC circuits. Sounds fun, right!? Don’t worry, it’s pretty easy and straight forward, and we’ll walk…
The Seesaw part 2: Basic PID Theory and Arduino Implementation
A few weeks ago we wrote a post about this small project where we’re building a seesaw which will balance a ball with the help of a proximity sensor, a servo and a PID controller implemented on an Arduino. All…
Electronics 101 pt. 2: Kirchhoff’s Laws
Two years ago we wrote a blogpost about the basic of basics within electronic theory: Voltage, Current and Resistance. Now we feel it’s time to pick the topic up again by introducing you to Kirchhoff’s Laws. Quick Intro Not only…
