This first video explores declarative vs. procedural knowledge through the lens of the Turing Test & Oracle machines. It’s intended to hook + ground the viewer in some basics before building towards Logic & Turing Machines. After this video we will dive deeper into procedural knowledge via. Algorithms. Then we’ll explore more history (arithmetic vs. formal logic) before building towards 20th Century ideas.

After a long period of research I’m happy to report Art of the Problem’s third episode is in production. This episode will act as the final piece of a CS trilogy. Here is the first video which gives an overview of the series: (or watch on YouTube)

I’ve also published an essay version of this video with extra links below (or read on Medium).

Around 100 years ago something really exciting was happening.

In early 2014 Tony DeRose (Senior Scientist and Lead of the Research Group at Pixar Animation Studios ) and Elyse Klaidman (Director of Pixar University and Archives) approached Khan Academy with an idea. They wanted to answer a question everyone asks in school at some point: “Why do I need to learn this?” Previously, Tony had given talks which try and engage children in mathematics by demonstrating how math lives at the intersection of design and technology at Pixar. It was clear that you could motivate kids to learn math and science by showing them how concepts they encounter in school are used at Pixar to make movie magic…Continue reading →

It wasn’t until 1920 that the question “how do we quantify information” was well articulated. This video introduces a key idea of Nyquist and Hartley, who laid the groundwork for Claude Shannon’s historic equation (Information Entropy) two decades later. In these early papers, the idea of using a logarithmic function appears, something which isn’t immediately obvious to most students fresh to this subject. If one ‘takes this for granted’ they will forever miss the deeper insights which come later. So, the goal of this video is to provide intuition behind why the logarithm was the ‘natural’ choice…

The following video/simulation was an attempt to bridge the gap between information as what we mean to say vs. information as what we could say. I view this as an important stepping stone towards Hartly,Nyquist and Shannon – which I will deal with next. It covers symbols, symbol rate (baud) and message space as an introduction to channel capacity. Featuring the Baudot multiplex system and Thomas Edison’s quadruplex telegraph.

Play with simulations used in video on Khan Academy:

The follow three video mini-series is a bit of an Engineering detour in the story of information theory. In order to easily grasp the ideas of Hartley and Shannon, I felt it would be beneficial to lay some groundwork. It began with my own selfish interest in wanting to relive some famous experiments & technologies from the 19th Century. Specifically, why did the Information Age arise? When and how did electricity play a role in communication? Why was magnetism involved? Why did Morse code become so popular compared to the European designs? How was information understood before words (and concepts) such as “bit” existed? What’s the difference between static electricity and current?

All of these questions are answered as we slowly uncover a more modern approach to sending differences over a distance…

@CEW4gifted Yes I worked on this project (which is still developing) - would love to know how they enjoyed the 'art of storytelling' module. 1 week ago
