Millions worldwide feel a personal connection to the scientists at Nottingham through Sixty Symbols and beyond. Cutting a third of Physics & Astronomy staff sends a devastating message about how universities value science and public engagement. x.com/LucienHeurtier…
Lucien Heurtier@LucienHeurtier

This petition reached the thousand signatories in 2 days only. Keep sharing & talking about it to your fellow physicists. This career path is too hard to accept universities can lightly fire so many faculty members who worked so hard to get there. Stand with UpN colleagues ✍🏻

Not heard of liquid antennas before x.com/AL33012/status…
安藤 しずおかAL330/JS2LLQ@AL33012

国際宇宙ステーション #ISS からの電波、三重県津市から液体アンテナでも取れました! CMの都合で高度の低い18:30頃までの受信でしたが51でしっかり復調しました👍 コップの水位は14センチ位で2m のλ/4には満たないですが波長短縮効果である程度のマッチングにはなっていたと思われます♪

Seems very possible that I will never understand what a modular form is. Still not a clue.

Didn't realise this is Euler's integral definition of the Gamma function. The integral can extend the factorial to non-integer values.

@forallcurious If you showed this image to a not-overly-bright ten-year-old, they would tell you why it was stupid. Good to put an upper bound on your target audience.

A map that shows how even a small, limited nuclear war between India and Pakistan would release enough particles into the atmosphere to trigger a small nuclear winter that would be felt worldwide.

@ACarl8610 @vintagemapstore That's wrong. The 2019 Science Advances study by Toon et al. explicitly models airbursts over urban targets to simulate realistic blast maximization and fire ignition. Later papers debate the fire models, but not the attack methods.

This study didn't hold up too well in further peer review. Basically its assumed a limited nuclear exchange with one hundred 50 kiloton detonations. The flawed part is they assumed ground bursts which is not likely to happen in reality. Most nuclear weapons are air bursts that explode several hundred meters above the ground to maximize damage radii and limit dust and fallout.

@Generatedsem @HighlandLT @graham025 @vintagemapstore Yup, most test situations were chosen to avoid this very outcome. The real danger isn't the blasts, it's the firestorms. In dry seasons, India and Pakistan are tinderboxes. The resulting global famine could kill billions over a few years.

@HighlandLT @graham025 @vintagemapstore We're talking about detonating nukes off remote, desolate islands, to nuking extremely dense cities full of flammable materials that would cause massive plumes of smoke

Would like to buy some "1J85" Mu-metal type material from Aliexpress for 50 Hz shielding. It's not outrageously expensive, but the likelihood receiving something useful seems low.

At 11.40pm last night, a monster positive lightning bolt lit up the sky just East of Norman, Oklahoma. And I was in Texas with my camera pointed above that storm, and captured the giant red sprite it produced.

@slothslug138620 @LeoDaVinciWave 3700 BCE would probably make the builders Anatolian farmers, not WHG. I believe the Anatolians had largely replaced the existing hunter gatherer population by then.

Sweet Track is a 5,830-year-old Neolithic timber walkway, discovered in 1970 once part of a network of wooden paths built to cross the marshy Somerset Levels on dry ground.

3D design in VR is just epic compared to a 2D screen and mouse. Gravity Sketch on Quest is one of the greatest design programs I've used on any platform.
