Flexible Buildings: The Future of Architecture | Engineering Documentary

World's Tallest Tower: Burj Khalifa - Dubai's Vertical City: https://youtu.be/NJI8mOv4VW4

Never before have there been so many people on Earth. The new world creates new challenges for us living together, one of the biggest being the infrastructure in the world we live in.

How can we ensure that the cities anonomyzing and isolating its inhabitants become places of encounter again? How can we use technology to create new spaces in areas where there is no space left? How can sustainable construction revolutionize the construction industry? - In the search for answers, the documentary presents current concepts and implementations from the core disciplines of architecture, development of building materials, and urban design.

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
- Original story with links to research papers can be found here: https://www.quantamagazine.org..../hobbyist-finds-math
- Build your own aperiodic tiling patterns with Kaplan's online tool: https://cs.uwaterloo.ca/~csk/hat/h7h8.html

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.

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.
