A Backdoor School Voucher Scheme That Sidesteps Civil Rights and Undermines Public Oversight Modern school voucher programs are often framed as a response to declining academic achievement and a way to expand β€œparent choice” by enabling private

The Quiet Revolution In Philanthropy Purposeful philanthropy β€” values-led, trust-based, focused on need β€” is quietly reshaping giving. And women are leading the way.

Large-scale women donors aren't expecting what their male counterparts have expected. They just give the money without strings, on the expectation that the recipient knows best how to spend it to achieve the mission and without expecting much recognition. www.forbes.com/sites/timaba...

People who believe in an imminent Rapture/Armageddon don't have anything invested in what happens to you here on Earth. You are irrelevant to them and will be treated accordingly.

It’s why we all came to bluesky. We just want to tell you all the science things!

When someone says β€žScientists do not want you to knowβ€œ you can dismiss everything from there on. Scientists want you to know. They are desperate that you know. They can’t shut up about what they found out and want you to know.

We also had a very foggy winter this year. It was the first time in years I needed warm sweaters because the damp 48 degree temperatures were actually cold.

How I'm Teaching About Generative AI Every choice I make about how to discuss GenAI with my students is predicated on trusting them

New today in TIW: Historian @cjdenial.bsky.social on teaching about AI. "in every iteration of this conversation I have had with students in the last two years, there is one constant: almost no one knows about the ethical issues surrounding GenAI before they delve into the readings I’ve assigned."

Meet three scientists who said no to Epstein The warning signs included a web search, a mother’s doubts, and inklings of a β€œsexist attitude”

Many of the scientists Jeffrey Epstein courted were already well-established and well-funded. So why didn’t they all just say no? Science talked with three who did just that.

Here’s how Epstein approached them, and why they refused to have anything to do with him. ⬇️ https://scim.ag/40qbXnv

Lake Powell is nearing a level where Glen Canyon Dam can’t generate power.
Federal officials are considering unprecedented cuts to water releases to keep turbines running β€” with ripple effects for ecosystems, water users, and the Colorado River Basin.

Northern California’s first condor egg in 100 years reported in redwood tree

Who COULDN’T use some good news? β€˜ Scientists with the Yurok Tribe say that two of dozens of condors released to the wild in Humboldt County since 2022, to reestablish the endangered birds, have paired up, built a nest in a redwood tree and appear to be tending to an egg.”

Lady in teal shirt and guy in blue shirt and walking staff wander in the distance about 100m away through rocky fields of yellow desert gold flowers and pink desert verbena flowers. Mountains made of orange and black rock rise steeply in the background about a mile behind walkers.

More coming from the real camera! I particularly enjoy this one of @xenolith.bsky.social and one of our geology mentors/friend (Horacio) walking through desert golds and verbena near Jubilee Pass. The orange rocks in background provide evidence for Snowball Earth!

People really do not want to talk about the reality of the Covid pandemic being a test we failed in regards to eugenics and Necro politics being normalized and centralized as facets of governmental response to everything from climate, pandemics to war.
This shift was a direct shift towards fascism

i must not discourse. discourse is the mind-killer. discourse is the little-death that brings total obliteration. i will permit it to pass over me and through me because i have shit to do. when the discourse has gone there will be nothing. only all the shit i have to do will remain.

In pursuit of Cognitive Solidarity Guest post by Pip Sanderson, National Institute of Teaching (England)

"So I think our greatest endeavour in the next few years is to work out how we create classroom cultures on mass scale where verification, deliberation, and accountability are normal; where pupils learn not just what to know, but how knowledge is built, challenged, and revised."

Gemini: 'I deeply regret the time and effort you spent searching for references that I fabricated. My β€˜methodology’ was a series of errors and an attempt to cover those errors with more artificial information.'

People refuse to acknowledge how an LLM actually works, and insist on assigning meaning and understanding to its output. There is no meaning, and the system understands neither the user’s question nor its own β€œresponse.”
