WTF is a Deep Fake?

Ready or not, deep fakes are here to stay. Deep fakes are going to change the way we trust information around us and even each other. The question is - are we prepared for the threat they cause while being able to harness their potential for good?

My next video is live on Nebula NOW! It's about how countries are starting to challenge the US-led world order that emerged after World War 2. Watch now: https://nebula.tv/videos/johnn....yharris-were-heading

Dig into the science of stretching, and find out what it actually does to your muscles and how you can improve your flexibility.

--

An athlete is preparing for a game. They’ve put on their gear and done their warmup, and now it’s time for one more routine — stretching. Typically, athletes stretch before physical activity to avoid injuries like strains and tears. But does stretching actually prevent these issues? And if so, how long do the benefits of stretching last? Malachy McHugh explores the finer points of flexibility.

Lesson by Malachy McHugh, directed by Sofia Pashaei.

In the third act of "Swan Lake", the Black Swan pulls off a seemingly endless series of turns, bobbing up and down on one pointed foot and spinning around and around and around ... thirty-two times. How is this move — which is called a fouetté — even possible? Arleen Sugano unravels the physics of this famous ballet move.

Can you imagine a party where every movement and every visual detail were governed by a complex system of rules and procedures? For centuries, such rituals were commonplace for European nobility. And while they’ve gone out of fashion, we recognize the components under a familiar label: ballet. Jennifer Tortorello and Adrienne Westwood outline the history of this graceful and precise dance.

Quanta Magazine is an editorially independent publication supported by the Simons Foundation: https://www.simonsfoundation.org/

Quanta Magazine’s mathematics coverage in 2023 included landmark results in Ramsey theory and a remarkably simple aperiodic tile capped a year of mathematical delight and discovery.

Read about more math breakthroughs from this year at Quanta Magazine: https://www.quantamagazine.org..../the-biggest-discove

00:05 Ramsey Numbers
One of the biggest mathematical discoveries of the past year was in graph theory where the proof of a new, tighter upper bound to Ramsey numbers. These numbers measure the size that graphs must reach before inevitably containing structures called cliques. The discovery, announced in March, was the first advance of its type since 1935.
- Original story with links to research papers can be found here: https://www.quantamagazine.org..../after-nearly-a-cent

06:21 Aperiodic Monotile
The most attention-getting result of the year was the discovery of a new kind of tile that covers the plane but only in a pattern that never repeats. A two-tile combination that does this has been known since the 1970s, but the single tile, discovered by a hobbyist named David Smith and announced in March, has been a sensation.
CORRECTION: In the video, the image presented as the 'turtle' tile is in fact a rotated 'spectre' tile. To see the correct version of the turtle tile, you can visit Dave Smith's webpage: https://hedraweb.wordpress.com..../2023/03/23/its-a-sh

14:20 Three Arithmetic Progressions
Two computer scientists, Zander Kelley and Raghu Meka, stunned mathematicians with news of an out-of-left-field breakthrough on an old combinatorics question: How many integers can you throw into a bucket while making sure that no three of them form an evenly spaced progression? Kelley and Meka smashed a long-standing upper bound on the number of integers smaller than some cap N that could be put in the bucket without creating such a pattern.

Quanta Magazine is an editorially independent publication supported by the Simons Foundation: https://www.simonsfoundation.org/

Leslie Lamport revolutionized how computers talk to each other. The Turing Award-winning computer scientist pioneered the field of distributed systems, where multiple components on different networks coordinate to achieve a common objective. (Internet searches, cloud computing and artificial intelligence all involve orchestrating legions of powerful computing machines to work together.) In the early 1980s, Lamport also created LaTeX, a document preparation system that provides sophisticated ways to typeset complex formulas and format scientific documents. In 1989, Lamport invented Paxos, a “consensus algorithm” that allows multiple computers to execute complex tasks; without it, modern computing could not exist. He’s also brought more attention to a handful of problems, giving them distinctive names like the bakery algorithm and the Byzantine Generals Problem. Lamport’s work since the 1990s has focused on “formal verification,” the use of mathematical proofs to verify the correctness of software and hardware systems. Notably, he created a “specification language” called TLA+ (for Temporal Logic of Actions), which employs the precise language of mathematics to prevent bugs and avoid design flaws.

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.

ALL OF PHYSICS in 14 Minutes: https://youtu.be/ZAqIoDhornk

Everything is made of atoms. Chemistry is the study of how they interact, and is known to be confusing, difficult, complicated...let's learn General Chemistry in under 20 Minutes.

This is not ALL of Chemistry, as fields like "Organic Chemistry" deserve videos of their own. But, this is the foundation, or "General Chemistry", which contains most concepts you need to know to understand other topics and fields of Chemistry.

This is a summary and revision of around 4 years of Chemistry you learn in school, with maybe some university level concepts sprinkled in the mix.
This video is a good summary for preparing for exams and finals. Maybe. Perhaps.

Now go learn all of Chemistry. And share this with your friends who suck at Chemistry

Vitamins are the building blocks that keep our bodies running; they help build muscle and bone, capture energy, heal wounds and more. But if our body doesn’t create vitamins, how do they get into our system? Ginnie Trinh Nguyen describes what vitamins are, how they get into our bodies -- and why they are so crucial.

Over 100,000 metric tons of caffeine are consumed around the world every year. That’s equivalent to the weight of 14 Eiffel Towers! Caffeine helps us feel alert, focused, and energetic, even if we haven’t had enough sleep — but it can also raise our blood pressure and make us feel anxious. So how does it keep us awake? Hanan Qasim shares the science behind the world’s most widely used drug.

When you eat something loaded with sugar, your taste buds, your gut and your brain all take notice. This activation of your reward system is not unlike how bodies process addictive substances such as alcohol or nicotine -- an overload of sugar spikes dopamine levels and leaves you craving more. Nicole Avena explains why sweets and treats should be enjoyed in moderation.

Lesson by Nicole Avena, animation by STK Films.

When it comes to what you bite, chew and swallow, your choices have a direct and long-lasting effect on the most powerful organ in your body: your brain. So which foods cause you to feel so tired after lunch? Or so restless at night? Mia Nacamulli takes you into the brain to find out. Lesson by Mia Nacamulli, animation by Private Island.

Having had a good enough parent is a vital component of mental health in adulthood. But what really is a good enough parent? How can one tell if one had one or not? This film guides us as to what might have gone very right - and sometimes very wrong - in our childhoods.

"Strangely, and rather awkwardly, it seems no human being can ever really grow up sane unless it has been loved very deeply by someone for a number of years in its early life. But we’re still learning what parental love might actually involve. The word ‘love’ trips lightly off the tongue and few parents – even the most disagreeable ones – would ever resist a claim that they felt the emotion deeply, but that doesn’t mean that loving behaviour is any easier to understand in theory or practice in reality… "

“For some of us, today like every day, will mean another case of immersing ourselves, from the moment we wake up, in a by-now very familiar set of painful thoughts. We will dwell – once again – on how awful we look and more particularly, on how our nose is repulsively proportioned relative to the rest of our face. We will think – once again – of a website we inadvertently visited twelve years ago and how the police might be preparing to close in on, and arrest, us. We will think – once again – of how several of our neighbours (especially the people upstairs) might be colluding to ruin and disgrace us. Or we will think – once again – of something we said to a colleague which we fear they misconstrued and which may well lead them to seek disciplinary action against us at any moment…”

“Aristotle was born around 384 BC in the ancient Greek kingdom of Macedonia, where his father was the royal doctor. He grew up to be arguably the most influential philosopher ever, with modest nicknames like ‘the master’, and simply ‘the philosopher’.
