This Real-Time Visual Shows How Slow Light Travels in the Vastness of Space

In this brilliant real-time visualization, we start with our planet to grasp just how fast light travels (300,000 km per second/186,000 miles per second). However, things quickly get mind-boggling when we use nearby objects in space like the moon, mars, and sun. The visualization was created by Dr. James O’Donoghue who is a Planetary Scientist at the Japanese Space Agency, JAXA. Before that, the good doc worked at NASA’s Goddard Space Flight Center. I love how elegantly a simple visualization can explain concepts like these. Read more: https://twistedsifter.com/videos/real-time-visual-of-how-slow-light-travels-in-space/

This is What Happens When You Teach an AI to Play Hide and Seek

The team at OpenAI observed agents discovering progressively more complex tool use while playing a simple game of hide-and-seek. Through training in their new simulated hide-and-seek environment, agents build a series of six distinct strategies and counterstrategies, some of which we did not know our environment supported. The self-supervised emergent complexity in this simple environment further suggests that multi-agent co-adaptation may one day produce extremely complex and intelligent behavior. You can find a detailed analysis and breakdown of this experiment at OpenAI Read more: https://twistedsifter.com/videos/teaching-an-ai-to-play-hide-and-seek/

Why Are 96,000,000 Black Balls On This Reservoir?

Veritasium took a boat through 96 million black plastic balls on the Los Angeles reservoir to find out why they’re there. The first time he heard about shade balls the claim was they reduce evaporation. But it turns out this isn’t the reason they were introduced. The balls are made of high density polyethylene (HDPE) which is less dense than water so they float on the surface of the reservoir even if they break apart. They are 10cm (4 inches) in diameter and contain about 210ml of water. So the…

Only in Japan Can Moving Be Described as a Pleasure

Ah Japan, the faraway land where everything is done more sensibly and efficiently. Take moving, a prospect so daunting, many of us would rather stay in our current home forever because the mere thought of packing/sorting/unpacking is too much to bear. I don’t know why, but I found this strangely therapeutic to watch. Read more: https://twistedsifter.com/videos/the-efficiency-of-japanese-movers/

This Brie(f) History of Cheese by TED-Ed is a Must For Cheese Lovers!

Before empires and royalty, before pottery and writing, before metal tools and weapons – there was cheese. As early as 8000 BCE, Neolithic farmers began a legacy of cheesemaking almost as old as civilization. Today, the world produces roughly 22 billion kilograms of cheese a year, shipped and consumed around the globe. Paul Kindstedt shares the history of one of our oldest and most beloved foods. Lesson by Paul S. Kindstedt, directed by Charlotte Cambon. Read more: https://twistedsifter.com/videos/brief-history-of-cheese-by-ted-ed/

9 Photography Tricks Advertisers Use to Make Food Look More Delicious

Photographing food in a studio creates unique challenges. The bright studio lights and lengthy setup times for the perfect shot means food sits around longer than usual. That’s why many commercial photo shoots include ‘food stylists’ that use tricks and hacks to make the food last longer (e.g., not melt) and appear even more delicious than real life.

Deconstructing John Coltranes Seminal Jazz Song Giant Steps

John Coltrane, one of jazz history’s most revered saxophonists, released “Giant Steps†in 1959. It’s known across the jazz world as one of the most challenging compositions to improvise over for two reasons – it’s fast and it’s in three keys. Braxton Cook and Adam Neely give Vox Earworm a crash course in music theory to help understand this notoriously difficult song. Even if you don’t understand a lick of music theory, you’ll likely walk away with an appreciation for this musical puzzle.
