The image features a detailed view of the barred spiral galaxy NGC 1365, also known as the "Majestic Island Universe." The galaxy is prominently displayed in the center, showcasing its bright core and spiral arms, with a bar structure extending through the center. The image is a sharp color photograph, highlighting intense star-forming regions at the ends of the bar and along the spiral arms, as well as details of dust lanes cutting across the galaxy's bright core. The background is filled with numerous stars, emphasizing the vastness of space.

The text below the image provides additional information about NGC 1365, noting that it is located 60 million light-years away in the Fornax constellation and is a dominant member of the Fornax galaxy cluster. It mentions the supermassive black hole at the galaxy's core and the role of the prominent bar in the galaxy's evolution. The image credit and copyright are attributed to Dietmar Hager, Eric Benson, and Torsten Grossmann. The text also hints at a future image titled "under the galaxy."

Epic Effort to Ground Physics in Math Opens Up the Secrets of Time

By mathematically proving how individual molecules create the complex motion of fluids, three mathematicians have illuminated why time can’t flow in reverse.

If you haven't muted me yet, here's a debunking of John Bell's "Heart attacks in Lille and Lyon".

Bell tells us the same logic applies to heart attack rates in Lille and Lyon as does to EPR-B, so he can ignore the rules of probability theory. Because, he says, neither city's causal influences can AFFECT the other's.

Note we are writing PROBABILITY THEORY. What can AFFECT does not matter—it is what is CORRELATED that matters!

So a counterexample is trivial to make...

Imaginary numbers are real

These odd values were long dismissed as bookkeeping. Now physicists are proving that they describe the hidden shape of nature

Happy birthday to #physicist Harriet Brooks (1876 - 1933) who discovered atomic recoil, Radon & recognized radioactive elements could undergo chains of transmutations into a series of new elements. #nuclear #physics⁠
⁠
She was Rutherford’s 1st grad student at McGill. After publishing her results in 1899 she completed her MSc in 1901 on “Damping of Electrical Oscillations,” before embarking on #radioactivity research.⁠ 🧵

My 9.25" x 12.5" linocut portrait of physicist Harriet Brooks (1876 - 1933) in a gradient of turquoise to green, shows her and her discovery of atomic recoil in gold (Radon gives off an alpha particle and daughter nucleus goes in opposite direction). A series of diagrams at the bottom shows how the Rutherford research group understood chains of radioactive active transmutations at the time.
