What the HECK is Time?! (in Einstein’s Relativity)
The Science Asylum – Apr 28, 2020 – 11:49
In special and general relativity, we imagine time as just another dimension of space in something called “spacetime.” Unfortunately, this picture leads to questions about determinism and free will. Is that really how it works? What does the concept of spacetime actually say about the universe and about time?

Science, Theoretically

h/t YouTube Suggestions for Mediterranean and Titan

That Time the Mediterranean Sea Disappeared
PBS Eons – Jan 9, 2020 – 11:55
How could a body of water as big as the Mediterranean just…disappear? It would take decades and more than 1,000 research studies to even start to figure out the cause — or causes — of one of the greatest vanishing acts in Earth’s history.
Haven’t seen this gal before, but her perkiness would fit right in on SciShow.

Science – Because, Stuff

5 Ecosystems Thriving in the Least Likely Places
SciShow – Apr 19, 2020 – 12:11
Around the world, living things have managed to build truly extraordinary ecosystems in some of the last places you would think to look. Understanding these ecosystems can help us protect or repair them, and it can also help us appreciate how incredibly resilient and creative living things can be. Hosted by: Hank Green

Seven Separate Science Stories

More down-to-earth than the other science post today.

  • Siamese Cat Mutants
  • Can We Reproduce in Space*
  • Subatomic Stories: Quarks
  • Benefits of Being Gooey
  • How Cold Can Earth Get?
  • “White Smoker” vents

*I haven’t watched it yet, but I dread to think what twists of language the reproduce-in-space story will use to avoid saying women get pregnant.

Science Across the Cosmos

Spend an hour on these three looks at the cosmos, and tell me you understood everything in every video.

The Science Asylum:
Could Flatland Be CURVED?!
Apr 13, 2020 – 12:58
Measuring the curvature of a space takes parallel transport and the Riemann curvature tensor (General Relativity). Let’s explore this using Flatland and Lineland, an old tool involving lower-dimensional spaces.

Gutenberg Project, the wonderful classic:
Flatland: A Romance of Many Dimensions (Illustrated)
by Edwin A. Abbot – 1884

title page; O day and night, but this is wondrous strange; FLATLANDS; A ROMANCE OF MANY DIMENSIONS Continue reading “Science Across the Cosmos”
