Researchers have tagged more than 400 monarch butterflies and are following their journeys on a cellphone app (and you can too). They are using a tiny solar-powered radio tag that weighs just 60 milligrams and sells for $200 (monarchs weigh 500 to 600 milligrams).
We Can Now Track Individual Monarch Butterflies. It’s a Revelation.

Reginald Dwayne Betts was locked up as a teenager for carjacking. While in prison, books were his escape. After his release he went on to be a poet, lawyer and founder of Freedom Reads — a nonprofit that installs libraries in prisons across the country.
A smuggled book changed his life. Now he’s built 500 prison libraries.

I spend all this time trying to figure out what the master plan is, and it always hits me: nothing. Just conspiracy brain worms all the way down. And the most smug self-righteousness as Kennedy and cronies destroy over a century of concerted scientific effort and hard work.

The best way to describe the change in my teaching practice is to say it was the result of a slow-burn retroactive epiphany caused by a series of events. Here is an article about one of those events. #iTeachPhysics

A couple centuries ago, philosophers mused that we'd never know what stars are made of.
Today, JWST is measuring the detailed composition of a protoplanet & possible moons forming around it. The results show complex reactions brewing around a newborn world. 🧪🔭

Shu Ha Ri reminds us that true expertise grows through progression — from imitation, to adaptation, to innovation — and that mastery is not about rejecting fundamentals, but about internalizing them so completely that they become the platform for original thought and effortless performance.
