In this video, I explain why some scientists believe that our universe is a hologram and we really live in the 2-dimensional projection of a higher dimensional space. First, I explain just what physicists mean by the “holographic principle.” The holographic principle says that the degrees of freedom inside a volume of space can be described by information on the surface of that volume at the same resolution. Then I explain that this relation goes back to ideas about the black hole entropy and string theory in space with a negative cosmological constant, the so-called Anti-de Sitter space. I briefly mention what the problems are with these arguments. I then discuss a recent idea of Verlinde & Zurek about how one could test holography experimentally. Finally, I tell you my own opinion about this. As so often, I am highly skeptical that wild speculation will lead to progress.
The Technological Singularity
The technological singularity is one of the most popular topics in computer science today. The implications of it are immense, and it could change the course of history. Artificial Intelligence is on the rise, and soon enough, we will have Superintelligence. It’s not slowing down any time soon. What is the technological singularity? When is it coming? Are robots actually a threat? I have a few ideas.
MACHINE LEARNING TUTORIAL (2020)
In this video we will look at the introduction to Machine Learning.
Artificial Intelligence vs Machine Learning vs Deep Learning Explained
This video discusses the basics of Artificial Intelligence, Machine Learning and Deep Learning.
The Map of Quantum Physics
This is the Map of Quantum Physics and quantum mechanics covering everything you need to know about this field in one image.
I made this map of quantum physics to lay out the ideas within the subject, to set some bounds on it so you know its not endless and to introduce you to lots of concepts that if you are interested in them you can dig deeper. When you are approaching a subject like this that’s so complicated it can be quite challenging because you don’t know where to start and you don’t know how all the concepts relate to each other so hopefully this will put everything in context.

The Future of Cryptocurrency for Nomads
Ashton Addison interviews Andrew on what it means to be a Nomad Capitalist, investing in emerging markets, gaining a second citizenship, cryptocurrency, banking, and luxury nomads.
What does it mean to go where you’re treated best? Andrew discusses the vision of Nomad Capitalist and how you can get the best deals out of life.
Do you have to be a citizen of Georgia to have an investment in Georgia? What about an investment in Cambodia? Some places have more investment restrictions than others.
Can you get citizenship by investment? Andrew discusses Turkey citizenship by real estate investment and the benefits of a second citizenship.
What impact does cryptocurrency have on the nomad lifestyle? Andrew discusses the future of cryptocurrency.
All wealthy people don’t have to live in the same five cities. Being a luxury nomad means living wherever you want. But what does Andrew recommend?
Tokenization and Decentralized Finance | Interaxis.io
Tokenization centers around the concept of disintermediation in a variety of processes. By replacing such intermediaries with code, decentralized finance democratizes the ability to trade real-world assets and potentially provides increased security, efficiency, and reliability to asset owners. There is also the potential to create more liquidity for investors.
The transparency, liquidity, and efficiency lends itself to greater coupling with Decentralized Finance – peer-to-peer lending and trading, data oracles, and hyper-customized portfolios.
This video gives you an analysis of the potential implications of tokenizing real-world assets. We go over financial processes, oracles, and blockchain concepts to help you understand the bigger picture of such a technology.
Facebook showed this ad to 95% women. Is that a problem?
In 2019, Facebook settled a lawsuit with civil rights groups following the revelation that advertisers using their platform could use the targeting options to exclude many specific demographics from seeing their ads. It’s now more difficult for an unscrupulous advertiser to use Facebook’s platform to discriminate.
However, even when you remove human bias from the system, Facebook’s ad delivery algorithms can result in biased outcomes. According to research from Northeastern University, Facebook sometimes displays ads to highly skewed audiences based on the content of the ad.
By purchasing ads and inputting neutral targeting options, the researchers found that the algorithmically determined audience for job ads for cleaners, secretaries, nurses, and preschool teachers was mostly women. The job ads for fast food workers, supermarket cashiers, and taxi drivers skewed toward Black users. The studies show that by targeting “relevant” users, these systems can reinforce existing disparities in our interests and our opportunities.
