What I made with IEEE in 2018

Posted in Uncategorized on December 12, 2018 by Brit Cruise

This year I produced two videos with my friends at IEEE (Information Theory Society) which cover two highly influential academic papers from the 20th Century. What’s really exciting about these videos is we had the original authors of the papers review the script during development (Abraham Lempel and Robert Gallager). On average we spent about 4 months writing & iterating on each script until we had something that is clear and correct.

Here they are:

Lempel-Ziv compression – One of the most influential compression algorithms of the 20th Century:

LDPC codes – One of the most versatile and widely applicable error correction codes which was about 40 years ahead of its time:

 

In 2019 I will continue this project with IEEE.

What is Bitcoin?

Posted in Uncategorized on May 28, 2018 by Brit Cruise

I spent a long time thinking about a way to explain the what/why/how’s of Bitcoin to general audiences (my Mom) in a way that doesn’t frustrate Engineers (no hand waving). I feel that all existing Bitcoin videos contain jargon that scares away the typical viewer. In this video I made a point to avoid using a single word that might confuse people. I don’t know if I succeeded but I tried my very very best…

 

Please share this video with anyone who still doesn’t “get it” – as it might fill in some gaps.

 

 

Art of the Problem & IEEE join forces with “The Information Age”

Posted in Uncategorized on November 5, 2017 by Brit Cruise

This year marked the beginning of a long term collaboration with IEEE Information Theory Society. The goal of our ‘Information Age’ series is to produce short videos which bring to life the most impactful ideas from Information Theory and show how they play a role in our lives today. The first two pilot videos we produced in 2017 were on Network Coding and Space-Time codes. In 2018 we’ll be exploring source coding, channel coding, quantum information theory and security. Below are the 2017 pilot videos. I’ve enjoyed working with Matthieu Bloch, Michelle Effros, Christina Fragouli & Suhas Diggavi on this project.

Space-Time codes (multi-input multi-output networks):

Does P = NP?

I spent many years pondering (making sense of) this question. I ended up building a entire Computer Science series just to get to it. This video explores complexity theory and the (P vs. NP question) and is the conclusion to the CS series. I hope it helps others get the the key realizations faster than i…

The birth of a market

The paper that started it all…

In November 2016 I felt something in the air…my gut told me it was time for the blockchain sector to finally have its moment. After playing around with cryptocurrencies for years it was the Ethereum launch that seemed to catapult this sector from a small network of crypto geeks into a larger pool of technology enthusiasts and investors looking to be part of web 3.0 – the decentralized internet.

How a Turing Machine works

Posted in Uncategorized on May 17, 2017 by Brit Cruise

For years I struggled to clarify exactly what a Turing machine needs to do, and more importantly, how Turing conceived of it. Even after I finished a CS degree I wasn’t able to “build one from scratch” because I hadn’t yet independently realized what he had…

Recently I had a moment of insight and hit on an improved analogy for the “program” of a Turing machine, which Turing describes as “a book”. I took this one step further and clarified that each page in this book can be thought of as a unique state. A page contains a single instruction to follow (which takes the form of a conditional statement). This subtle step is something Turing didn’t include in his paper (instead he skipped ahead and simply refers to it as a ‘big table’, which can be tough to digest at first)

I feel this is the key to make the mechanism behind Turing machines more concrete and intuitive for the new learner. I hope Turing would approve of my modification to his analogy…and after reading his paper some 20 times, I can say with certainty that he would.

Here is the video on how it all works (this is also the 2nd last video in the CS series)

 

What is a Computer?

Posted in Uncategorized on November 3, 2016 by Brit Cruise

This video was on the tip of my tongue for years, it feels wonderful to finally move on. It features Aristotle, Leibniz, Adam Smith and Charles Babbage. It’s the main “case study” for this series, after which we’ll move into more modern views on computers and computability.
