@Bigqadi I once calculated that the very top marathon runners go at pretty much exactly the same speed as I can do 100m (about 17 seconds)

Researchers from the University of Bonn in Germany have re-analysed observations of galaxy clusters and argue that much of the clusters’ “missing” mass may not be exotic dark matter but ordinary matter in the form of faint stellar remnants.
Galaxy clusters have long required about five times more mass than what is visible to explain the observed galaxy motions, an observation that is usually attributed to dark matter. But the authors combined gravitational lensing, X-ray, and optical data with models of star formation and found that the total mass in stars and their remnants could be almost twice as high as previously estimated.
This matters because Modified Newtonian Dynamics (MOND), an alternative to dark matter, seems to not work well for galaxy clusters. The discrepancy between the MOND predictions and the observations from galaxy clusters almost goes away with the new estimate, while dark matter no longer works all that well.

@SandyofSuffolk Tinned soups are liquid salt mines...avoid
English

Heinz soups are a rip off.
Their oxtail soup is very orange. Because it contains mostly carrot. Their chicken soup has no pieces of chicken in. It's just watery slush.
Aldi's oxtail soup is a third of the price and is brown and their chicken soup has small bits of chicken in.
Ditch the big names people.

Left: Me and my goats in Afghanistan.
Right: Me after my PhD from one of the UK's top universities.
Conclusion: Farage is an ignorant coward who thrives on hate mongering and racial stereotypes.

I remember when they added an extra number to landlines.

Does anyone who grew up before social media still remember their parents’ landline number??

@AaronAmarok Well after 40 years driving a manual I got an EV and baby it's better, ooh yeah
English

I always found it so funny how more and more people think manuals are this unforgiving task that suits only the strongest most talented drivers when in reality its the easiest thing ever

@gaughen I use two of them for grunt work in a programming job I'm doing. They contradict each other all the time.

@RogierBrussee Beyond a certain level of abstruseness and vast number of preconditions it gets a bit silly.

This is rather a beautiful example of modern math with very precise and profound statements (not to mention the great use Litt made of it for proving that certain Taylor expansions have rational coefficients) that look like total gibberish to those outside (and many inside) math.

Faltings wins the Abel prize! Obviously his work is immensely influential; in my own research I've used his results on p-adic Hodge theory quite a bit. Aside from his proof of the Mordell conjecture, this is my favorite result of his:

@benryanwriter Why do I keep reading that paperbacks are drifting towards non-existence? I mean, why do people think it's true?

RIP mass market paperbacks.
Here’s my shelf of them:
