Michel Foucault was a philosophical historian who questioned many of our assumptions about how much better the world is today compared with the past. When he looked at the treatment of the mad, at the medical profession and at sexuality, he didn't see the progress that's routinely assumed.

FURTHER READING

“Michel Foucault (1926-1984) was a French 20th-century philosopher and historian who spent his career forensically critiquing the power of the modern bourgeois capitalist state, including its police, law courts, prisons, doctors and psychiatrists. His goal was to work out nothing less than how power worked and then to change it in the direction of a Marxist-anarchist utopia. Though he spent most of his life in libraries and seminar rooms, he was a committedly revolutionary figure, who met with enormous popularity in elite Parisian intellectual circles (Jean Paul Sartre admired him deeply) and still maintains a wide following among young people studying at university in the prosperous corners of the world…”

The nanoscopic world is wild!! Looking at basic objects like a grain of salt under an electron microscope looks like nothing you would have expected. Furthermore, have you ever wondered whether seeing a single atom is possible? Or how do scientists and engineers create only a few nanometers wide transistors? In this video, we will explore the electron microscope and how they are used to see nanoscopic objects. Specifically, we'll look at the Transmission Electron Microscope and the Scanning Electron Microscope and dive into how they work.

On April 8, 2024, the Moon’s shadow fell upon the Earth, creating a total solar eclipse across North America. If you had the chance to see it, you're surely glad you didn't miss it. It’s an amazing coincidence that total eclipses happen at all — and that we’re alive at a time when we can see and predict them. We made this video so you can learn how to watch an eclipse safely, what to look for during an eclipse, why eclipses happen, and how eclipses have helped advance scientific research.

Scientists like Prof Sinclair have evidence of speeding up, slowing, and even reversing aging.
Thanks to LastPass for sponsoring this video. Click here to start using LastPass: https://ve42.co/VeLP

What causes aging? According to Professor David Sinclair, it is a loss of information in our epigenome, the system of proteins like histones and chemical markers like methylation that turn on and off genes. Epigenetics allow different cell types to perform their specific functions - they are what differentiate a brain cell from a skin cell. Our DNA is constantly getting broken, by cosmic rays, UV radiation, free radicals, x-rays and regular cell division etc. When our cells repair that damage, the epigenome is not perfectly reset. And hence over time, noise accumulates in our epigenome. Our cells no longer perform their functions well.

To counter this decline, we can activate the body's own defenses against aging by stressing the body. Eat less, eat less protein, engage in intense exercise, experience uncomfortable cold. When the body senses existential threats it triggers longevity genes, which attempt to maintain the body to ensure its survival until good times return. This may be the evolutionary legacy of early bacteria, which established these two modes of living (repair and protect vs grow and reproduce). Scientists are uncovering ways to mimic stresses on the body without the discomfort of fasting. Molecules like NMN also trigger sirtuins to monitor and repair the epigenome. This may slow aging.

Reversing aging requires an epigenetic reset, which may be possible using Yamanaka factors. These four factors can revert an adult cell into a pluripotent stem cell. Prof. Sinclair used three of the four factors to reverse aging in the retinal cells of old mice. He found they could see again after the treatment.

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.

5:43 Most smartphones use a pentile subpixel layout which is 2x Green for 1x Red and 1x Blue.

7:25 1Pixel = 1G+1B or 1G + 1R. Thus the latest phones are closer to 6.67Million itty bitty lights.

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.

We all are, at times, the victims of one of the cruellest and most remorseless of all mental afflictions: obsessive thinking. But why?

FURTHER READING

You can read more on this and other subjects here: https://9qq0.short.gy/m0b8dK

“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…”

https://www.stamps.com/JohnnyHarris Thanks to Stamps.com for sponsoring the show!

I will never be able to look at bananas the same way again. The history behind this fruit is filled with government coups, propaganda, and predatory corporations.
This is the story of how US imperialism gave us crappy bananas - and why the ones in your kitchen might be doomed.

FURTHER READING

“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’. One of his big jobs was tutoring Alexander the Great, who soon after went out and conquered the known world...”
