At 17, Hannah Cairo Solved a Major Math Mystery | Quanta Magazine After finding the homeschooling life confining, the teen petitioned her way into a graduate class at Berkeley, where she ended up disproving a 40-year-old conjecture.

Why would mathematics of all fields reject a prodigy applying to admission to grad school? Kudos to Johns Hopkins and U Maryland for being flexible. www.quantamagazine.org/at-17-hannah...

Somewhere someone read a policy and thought “I don’t have to think. A decision is made by this policy. My life is easy.”

Happy Friday to everyone who might be concerned that he has possession of the nuclear codes, blames the messenger for tanking the economy & would gladly pardon a monster to save his own thin orange skin.

'I won't back down': How and why Canadians are boycotting the U.S. | CBC News We asked Canadians to tell us more about how and why they are boycotting U.S. goods and travel. Here's what you told us.

On my last visit the “American” sections were replaced with Canadian. It was brilliant.

Newly discovered giant stick insect could be Australia's heaviest Naturalists have made the discovery in the misty rainforests of Far North Queensland where tree canopies reach more than 30 metres above the ground and many species are believed to still be unknown.

Who can’t love a giant stick insect?

Trump foreign policy: "When we sign a trade agreement with another country, we retain the right to renege at any time."

Trump domestic policy: "When we strike a budget agreement with the other party, we retain the right to renege at any time."

This is a great thread to understand why learning physics concepts can be a misguided approach to learning (to do) physics, or teaching it. Conceptual knowledge is necessary but not sufficient. #iTeachPhysics

“It is probably too much to expect that Trump’s base will defect en masse. But we can be thankful for small victories. After years of complete impunity, Trump has finally discovered that his power to brainwash his idolaters is finite”

Beyond belief: Reframing teaching as a science-based profession
Look at the table below. Replace 'teacher' with 'doctor' and see what you prefer. Why do you think that evidence-informed doesn't chain the doctor but chains the teacher? #Edusky

Sounds like an episode of James Burke’s Connections.

This is too funny.

And sad, it is just so sad.

Defending the Science of Learning Effective Instruction isn’t a matter of chance, but of design.

Hard to take seriously the red-white-and-blue rhetoric of freedom on a 4th of July where the US president has cut off aid to a democracy fighting for its independence against ferocious attack by a foreign tyrant.

More reason for the rest of the world carrying on with everything on our own.

Evidence for a sub-Jovian planet in the young TWA 7 disk  - Nature Using the James Webb Space Telescope's Mid-Infrared Instrument, a study reports evidence for a direct detection of a cold, sub-Jupiter-mass planet in the disk of the star TWA 7. 

Wow! For the first time ever, the James Webb Space Telescope has revealed an exoplanet by directly imaging it. The newfound world has a mass similar to Saturn and orbits inside the debris disk surrounding a very young star just 111 light years away. via @nature.com

Congratulations. Never stopped listening to you even after moving to Australia.

YouTube video by Centre for Independent Studies Evidence vs Ideology: Why the Science of Learning Matters?

I’ve watched a generational decline in my profession, and it’s come from within. We’ve added complexity to teaching, instead of seeing the benefits of clarity.

These discussions are helpful in clearing the way.

'Wasn't part of the syllabus': Australia's 30-year failure in teaching writing New resources launched by Australia's Education Research Organisation will arm all teachers with the skills to teach writing.

Writing, by hand on paper with pen, is a skill that has long been neglected as a valuable learning tool. Writing while learning is a physical gesture a student needs to repeat when they need to express what has learned.

Every machine in a Hospital that diagnoses your body without cutting you open is based on a principle of Physics, discovered by a Physicist who had no interest in Medicine.

If you think the world doesn’t need Basic Science, or that somehow Science has failed you, think again.
