The global economy is in crisis. The exponential exhaustion of natural resources, declining productivity, slow growth, rising unemployment, and steep inequality, forces us to rethink our economic models. Where do we go from here? In this feature-length documentary, social and economic theorist Jeremy Rifkin lays out a road map to usher in a new economic system.
A Third Industrial Revolution is unfolding with the convergence of three pivotal technologies: an ultra-fast 5G communication internet, a renewable energy internet, and a driverless mobility internet, all connected to the Internet of Things embedded across society and the environment.
This 21st century smart digital infrastructure is giving rise to a radical new sharing economy that is transforming the way we manage, power and move economic life. But with climate change now ravaging the planet, it needs to happen fast. Change of this magnitude requires political will and a profound ideological shift.

The entire field of mathematics summarised in a single map! This shows how pure mathematics and applied mathematics relate to each other and all of the sub-topics they are made from.

To err is to human, and I human a lot. I always try my best to be as correct as possible, but unfortunately I make mistakes. This is the errata where I correct my silly mistakes. My goal is to one day do a video with no errors!
1. The number one is not a prime number. The definition of a prime number is a number can be divided evenly only by 1, or itself. And it must be a whole number GREATER than 1. (This last bit is the bit I forgot).
2. In the trigonometry section I drew cos(theta) = opposite / adjacent. This is the kind of thing you learn in high school and guess what. I got it wrong! Dummy. It should be cos(theta) = adjacent / hypotenuse.
3. My drawing of dice is slightly wrong. Most dice have their opposite sides adding up to 7, so when I drew 3 and 4 next to each other that is incorrect.
4. I said that the Gödel Incompleteness Theorems implied that mathematics is made up by humans, but that is wrong, just ignore that statement. I have learned more about it now, here is a good video explaining it: https://youtu.be/O4ndIDcDSGc
5. In the animation about imaginary numbers I drew the real axis as vertical and the imaginary axis as horizontal which is opposite to the conventional way it is done.

How the automobile differential allows a vehicle to turn a corner while keeping the wheels from skidding.
Differential steering From Wikipedia, the free encyclopedia
https://en.wikipedia.org/wiki/Differential_steering
Differential steering is the means of steering a land vehicle by applying more or less drive torque to one side of the vehicle than the other. Differential steering is the primary means of steering tracked vehicles, such as tanks and bulldozers, is also used in certain wheeled vehicles commonly known as skid-steer, and even implemented in some automobiles, where it is called torque vectoring, to augment steering by changing wheel direction relative to the vehicle. Differential steering is distinct from torque steer, which is usually considered a negative side effect of drive-train design choices.

Google Tech Talk
January 6, 2011
Presented by Ron Garret.
ABSTRACT
Richard Feynman once famously quipped that no one understands quantum mechanics, and popular accounts continue to promulgate the view that QM is an intractable mystery (probably because that helps to sell books). QM is certainly unintuitive, but the idea that no one understands it is far from the truth. In fact, QM is no more difficult to understand than relativity. The problem is that the vast majority of popular accounts of QM are simply flat-out wrong. They are based on the so-called Copenhagen interpretation of QM, which has been thoroughly discredited for decades. It turns out that if Copenhagen were true then it would be possible to communicate faster than light, and hence send signals backwards in time. This talk describes an alternative interpretation based on quantum information theory (QIT) which is consistent with current scientific knowledge. It turns out that there is a simple intuition that makes almost all quantum mysteries simply evaporate, and replaces them with an easily understood (albeit strange) insight: measurement and entanglement are the same physical phenomenon, and you don't really exist.

Dr. Ron Garret was an AI and robotics researcher at the NASA Jet Propulsion Lab for fifteen years before taking a year off to work at Google in June of 2000. He was the lead engineer on the first release of AdWords, and the original author of the Google Translation Console. Since leaving Google he has started a new career as an entrepreneur, angel investor and filmmaker. He has co-founded three startups, invested in a dozen others, and made a feature-length documentary about homelessness.

The field of computer science summarised. Learn more at this video's sponsor https://brilliant.org/dos
Computer science is the subject that studies what computers can do and investigates the best ways you can solve the problems of the world with them. It is a huge field overlapping pure mathematics, engineering and many other scientific disciplines. In this video I summarise as much of the subject as I can and show how the areas are related to each other.

A couple of notes on this video:
1. Some people have commented that I should have included computer security alongside hacking, and I completely agree, that was an oversight on my part. Apologies to all the computer security professionals, and thanks for all the hard work!
2. I also failed to mention interpreters alongside compilers in the complier section. Again, I’m kicking myself because of course this is an important concept for people to hear about. Also the layers of languages being compiled to other languages is overly convoluted, in practice it is more simple than this. I guess I should have picked one simple example.
3. NP-complete problems are possible to solve, they just become very difficult to solve very quickly as they get bigger. When I said NP-complete and then "impossible to solve", I meant that the large NP-complete problems that industry is interested in solving were thought to be practically impossible to solve.

Cybersecurity and CyberWar discusses the cybersecurity issues that challenge everyone: politicians wrestling with everything from cybercrime to online freedom; generals protecting the nation from new forms of attack while planning new cyberwars; business executives defending firms from once unimaginable threats; lawyers and ethicists building new frameworks for right and wrong. In Cybersecurity and CyberWar, New York Times best-selling author Peter W. Singer and noted cyber expert Allan Friedman team up to provide the kind of easy-to-read, deeply informative resource book that has been missing on this crucial issue of 21st century life. The book is structured around the key question areas of cyberspace and its security: how does it work and why does it matter? Also discussed are the important (and entertaining) issues and characters of cybersecurity, from the "Anonymous" hacker group and the Stuxnet computer virus to the new cyber units of the Chinese and US militaries.
Peter W. Singer is a Senior Fellow and the Director of the 21st Century Defense Initiative at the Brookings Institution.

Modern encryption techniques provide several important security properties, well known to most practitioners. Or are they? What are in fact the guarantees of, say, HTTPS TLS cipher suites using authenticated encryption, IPSec vs. SSL VPNs, Property Preserving Encryption, or token vaults? We live in an era of embedded Hardware Security Modules that cost less than $1 in volume, and countless options now exist for encrypting streaming network data, files, volumes, and even entire databases. Let's take a deep dive into the edge of developed practice to discuss real-world threat scenarios to public cloud and IoT data, and look closely at how we can address specific technical risks with our current encryption toolkits. Advanced math not required.

One of the thorniest faces of free speech debate is the tension between free expression as an abstract principle and kinds of speech that harm, such as hate speech, incitements to violence, or uses of information which can cause economic damage or threaten security or privacy. And technologies change how information can move, and harm. This week we put a historian of the earliest post-printing-press debates over free speech in dialog with a historian of the information practices of hate groups in America.
