This is great. I am not a fan of the oscillator example - makes it seem like a physics niche thing. But so useful for us population-thinkers. I might write up a post using a population dynamics differential equation example. If I can finish cloning myself. Yeah. www.youtube.com/watch?v=FE-h...

The ocean regulates our climate, nourishes hundreds of millions of people around the world, and produces about half of the oxygen on Earth. 🌊 ✨
So, when you take a deep breath this #NationalRelaxationDay, be sure to thank the ocean. 💙

Defense is now questioning Lairmore on cross-examination. They show a video still of the sandwich and wrapper on the ground, post-throw.
"Do you recognize that sandwich?" the attorney asks.
Lairmore won't confirm.
"I did not go back to collect it," he says.

This is a truly astonishing image. The yellow spot is a planet (WISPIT-2b) orbiting a star (its light blocked by a coronagraph) carving out a 'lane' in the dusty ring-shaped planetary nebula from which it was born. A snapshot of our own solar system, as it probably looked 4.5 billion years ago.

Energy conversions never cease to amaze
to give you an idea of how much energy is released in storms like the one hitting TX:
* per the WaPo, 1.8 trillion gallons of rain have fallen
* conversion of vapor to this much water releases 15 EJ
* if this occurred over 24 hours, it corresponds to 178 TW — 10 times what human society consumes.

So, here it is. Thanks to a new state law that was NEVER DEBATED, Indiana University has committed itself to abolishing majors in African-American/African Diaspora Studies: American Studies; Art History; French; Italian; Religious Studies etc. DOZENS of majors. www.ipm.org/news-section...
Indiana public colleges cut almost 20% of degrees

The news is downright bad, and weird, lately. But my research team arrived back home from an excellent field season in Central Europe. With some surprises: iron accumulations (tech term=plinthite) in buried soils! Usually found in much warmer/humid areas. We’re excited to see what the IRSL ages say!
