This is nothing short of astonishing.

— Kit Yates (@Kit_Yates_Maths) October 13, 2020

SAGE asked for a two week “circuit-breaker” 3 weeks ago.

Yesterday we heard from Chris Whitty that he doesn’t think the highest tier of restrictions will turn the tide.

What are we doing?

素人には15℃で267GPaというのが想像できない｜「超伝導状態が達成される温度を摂氏15度まで引き上げた。この超伝導効果は、光化学的に合成される炭素質水素化硫黄の三元系において、267ギガパスカルの圧力下で観察された。」 https://t.co/rEBlAcbDSV

"Why Study Mathematics?" has landed! I'm very excited to have my copy. The @LPPbooks team and I hope it will be useful and inspiring for students considering a maths degree, and their teachers and families. Preorder now and you'll have your copy soon! https://t.co/2OnYJumDcw pic.twitter.com/Yf6ZqPITvi

I can speculate about NRA + MAGA, but it would end up being an ANAGRAM joke.

For me this sort of highlights the need for @IndependentSage . I feel bad for the government scientists who are hamstrung by their positions and unable to speak out. https://t.co/Ude1Qzehe3

Ever wanted (x+y)^2 to equal x^2 + y^2? There's a math for that. See my newest Mathematical Enchantments piece, "When 1+1 Equals 0." https://t.co/JzbhucRhe8 pic.twitter.com/VPs60mTwiX

A summary of the data from today's @IndependentSage briefing.

Prepared in collaboration with the data dynamo herself, @chrischirp.

I should warn you there isn't much good news in here.

Why do we define logical implication p ⇒ q the way we do? Is it an arbitrary convention, just a shorthand for ¬p ∨ q, or a fundamental concept of great importance?

What is i^i? Easy, right? i=E^(pi i/2), so i^i = E^(-pi/2)=0.208...

— Alex Kontorovich (@AlexKontorovich) October 16, 2020

But i is also E^(5 pi i/2). So maybe i^i = E^(-5pi/2) = 0.000388...

That's a big difference! Which one is right?

We knew back in April that a functioning TTI system was going to be crucial to keep the virus in check in the future.

— Kit Yates (@Kit_Yates_Maths) October 13, 2020

The impact of the failure to properly implement it, despite the huge sums of money thrown at it, is quite literally devastating. https://t.co/rBOyX18U8v

'Herd immunity' has been reached during previous epidemics of influenza, measles and seasonal coronaviruses. But it's subsequently been lost (and then regained). What are some of the reasons for this? 1/
