Mindscape 321 | David Tong on Open Questions in Quantum Field Theory. I *know* you've been worried about why the electroweak theory cannot be defined on discrete spacetime. #MindscapePodcast

100 years ago today, #OTD in 1925, Edwin Hubble announced that Andromeda and other spiral nebulae were definitely separate galaxies outside the Milky Way, in a paper read to an AAS meeting by H.N. Russell.

There was no doubt that the Universe was more than just our little island of stars. 🧪 🔭 ⚛️

This was eloquently pointed out by physicist JJ Thomson more than a century ago.

If you want R&D to truly thrive in this country, you have to encourage both, but not by tying them more closely together. 3/3

A new claim that dark energy isn’t necessary, we just need to properly account for inhomogeneities in the universe. Maybe. But his idea has been discussed for a long time - David Wiltshire, an author here, has been pushing it for 20 years, and others have also looked at it. (1/n)

Nothing better than a light reading in the holiday season. ;)

Introduction to Black Hole Thermodynamics
These notes aim to provide an introduction to the basics of black hole thermodynamics. After explaining Bekenstein's original proposal that black holes have entropy, we discuss Hawking's discovery of ...

Happy birthday to #mathematician & #astronomer Johannes Kepler (1571-1630)! 🐡🧪🔭🧮 #histsci We remember him for his role in the Scientific Revolution & his 3 laws of planetary motion in particular. His laws modified Copernicus’ heliocentric model; he replaced the circular orbits with elliptical ones &
My linocut portrait of Johannes Kepler on cream coloured washi paper. Kepler is in Renaissance garb printed in indigo. He holds a compass and rests his hand on his model of nested Platonic solids from Mysterium Cosmographicum, printed in gold ink. Above that in silver in are 7 musical staves with notes next to symbols for related planetary bodies: Mercury, Venus, Earth and Moon, Mars, Jupiter and Saturn. Over his other shoulder are 3 schematic diagrams drawn in ellipses (oriented with the semi-major axes horizontal) in magenta. The top one relates to his first law and shows an ellipse cut in two horizontally, the two foci labelled F and F’ and a triangle drawn to a point P on the ellipse (FPF’). The middle ellipse (2nd law) shows the Sun at a focus, and a series of circles on the ellipse as a planet such that the sections are equal area and alternate colouring (magenta or none) like a peppermint. The bottom ellipse (3rd law) is cut in half with semi-major and semi-minor axes shown

Albert Michelson, pioneer of optical interferometry, was born #OTD in 1852.

Michelson refined measurements of the speed of light, failed to find evidence of the aether, and developed a method that now underlies gravitational wave detection. 🧪 ⚛️ (1/n)
