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.

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.

A ton of your devices use Bluetooth to communicate wirelessly. But how does Bluetooth work? In this video, we'll dive into the details of how your smartphone sends audio to your wireless headphones. Bluetooth is rather complicated and thus we're going to use a number of analogies and tools to explain it fully.

Design and branding are inherently a part of human nature. They serve as a way of signaling to others, non-verbally, who we are, what we believe in, and what is important to us.

There was a time when consumers were exclusively interested in a company's products — upgrades, different flavors, different colors.

But today, consumers want to know if the companies that they are buying from are worthy of their money. Do the companies practice good ethics? Do they have certain values? That's something that we have really never seen before.

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.

What is the best life we can live? How can we cope with whatever the universe throws at us and keep thriving nonetheless? The ancient Greco-Roman philosophy of Stoicism explains that while we may not always have control over the events affecting us, we can have control over how we approach things. Massimo Pigliucci describes the philosophy of Stoicism.

Lesson by Massimo Pigliucci, animation by Compote Collective.

Mastering any physical skill takes practice. Practice is the repetition of an action with the goal of improvement, and it helps us perform with more ease, speed, and confidence. But what does practice actually do to make us better at things? Annie Bosler and Don Greene explain how practice affects the inner workings of our brains.

99% of all internet traffic – from this video to your Pokemon Go account to your family WhatsApp group – runs on a hidden network of undersea cables. Why should you care? Because modern life is increasingly dependent on those slinky subaquatic wires. And they get attacked by sharks from time to time.

Whether you're making a resume for your first job, or improving upon a good resume you already have been using for years, it's very important to get the basics principles right before moving on to fancier resume writing tips.

🤔 So how do write a resume or make a strong CV?

Who knew writing a good resume would be so simple? 😉

All jokes aside, this video contains practical resume writing tips following each one of Austin's findings, and I walk you through each of the 5 Golden Rules so you know the do's and dont's about writing a resume 💯
