Along with #dark #energy, dark #matter represents a major embarrassment for #physicists. Together, these two unknowns mean that over 95 per cent 📊 of the #universe is made up of stuff not #categorised 📉 in the #standard model of #particle #physics, our best theoretical picture of #material #reality https://www.newscientist.com/definition/dark-matter
This is one of my favorite pictures. It feels like it was taken yesterday… but it was taken in a Paris public garden nearly a hundred years ago. Everything feels modern: the composition, the casualness, the daring clothes, haircuts, and accessories.
The women are unknown, but I can't help wondering how they fared a few years later in nazi-occupied Paris.

Couldn't help it and did this last night. I'm still in awe at the level of detail in this image! Look at those spiral dust lanes.

This is AMAZING
Green Days “Boulevard of Broken Dreams” redone in classical Classical Latin https://youtu.be/Mip30YF1iuo
The craziest part? Because Latin isn’t nearly as “influenced” by different roots of its era (unlike the English of today) the alliterations, tonal shifts etc. Can flow much more consistently through the melody! It’s fascinating to listen to

"An Elliptic Curve Primality Proving (ECPP) algorithm was used via a primality proving program, Primo 4.3.0 - LX64, to generate a primality certificate which deterministically verifies the primality of p. The certification process took 39 days and 8 hours to complete using an AMD Ryzen Threadripper 2950X (16-Core, 32-Thread, 3.5GHz Base)."
