Happy birthday to Danish #physicist Niels Bohr (1885-1962). One of his most famous contributions to quantum mechanics was the Bohr-Rutherford model of the atom. Bohr is shown next to the Bohr model of the Hydrogen atom (all the concentric circles are actually at the appropriate spacing, proportional to the n squared). Bohr proposed that the orbits of electrons were somewhat like planetary orbits 🧵

My linocut of Niels Bohr with the Bohr model of the hydrogen atom and Balmer series of spectral lines. Bohr is printed in blue-grey and wearing a suit. Concentric rings of silver represent energy levels in hydrogen and overlap his head. Squiggly lines go between pairs of silver orbits and match the colours of the line spectra printed below him (left to right: red, cyan, blue and violet. H-alpha is red and caused by a jump from the 3rd to 2nd orbit; H-beta is cyan and caused by a jump from the 4th to 2nd orbit; H-gamma is indigo and caused by a jump from the 5th to 2nd orbit; and H-delta is violet and caused by a jump from the 6th to 2nd orbit.

were all the same.” She was a #physicist, #crystallographer, #pacifist & prison reformer. She was the 1st to employ Fourier spectral methods for structure & used them to solve the structure of hexachlorobenzene in ‘31. In ‘45 she was one of the 1st 2 women elected Fellow of the Royal Society & was the 1st woman: tenured professor at UC London, president of the International Union of Crystallography & president of the British Association for the Advancement of Science.   🧵2/

Day 24 #SciArtSeptember prompt numbered: the 2nd woman to win the Nobel Prize for #physics: German-American theoretical #physicist Maria Goeppert Mayer (1906-1972). As the series of increasingly large atomic nuclei grows with additional nucleons (protons p & neutrons n) from hydrogen to transuranic elements, there are points where the binding energy of the next nucleon is a lot lower than the last. So there are a series of quantum “magic numbers” 🧵

My linocut portrait of Maria Goeppert Mayer on 11” x 14” white Japanese paper shows the nuclear shell model energy states in lime green up the left side. Next to this are the magic numbers rising vertically (sums of available energy states): 2, 8, 20, 28, 50, 82, 126 and associated elements for nuclei with those numbers of protons: He, O, Ca, Ni, Sn, Pb with the final hypothetical element unlabelled, all in dark blue. A 3/4 portrait from the chest up in dark blue is all the right side. Mayer has short hair, and wears a dark blouse with long thin white scarf draped around her neck, untied. Below the magic numbers are increasingly large representations of nuclei with increasing numbers of gold and white nucleons like clumps of balls.

This is the best explainer on the #physics of #knitting (and why it's both technically and historically important) that I've ever seen. You don't have to #knit or be a #physicist to enjoy it, but neither will your knowledge be insulted if you are either or both of those things. Well worth watching.

One astro/cosmologist explained the cultural difference this way:

#Physicist have a high tolerance for exploration of rabbit hole theories when there are data anomalies. Theories are built, and even though 99% of these turn out to not describe our Universe, it is a form of personal development of one's #curiosity, and the math developed will surprisingly often be reusable for a completely different problem. #astrodon #AcademicChatter

#OnThisDay Birth Anniversary of René Goscinny (1926) - creator of #Asterix.

Birth Anniversary of Danish #Physicist Hans Christian Ørsted (1777) - who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism.

Happy Birthday Magic Johnson (1959).

Sam Altman claims that science will be finished by AI in a few years. This is reminiscent of 20th century scientists who said similar things, but still, science is far from finished. I think the more we know about science, the more unanswered questions we will be left with.

How to Become a Physicist #howto #diy #Physicist

post MSc very difficult being at home watching physicist husband going to work to pursue what he loved. He insisted she return to grad school. Admitted to Georgetown at 23, expecting 2nd child. Writing her thesis, advisor Heyden got her in contact with #physicist George Gamow, who worked at nearby APL & adjunct at George Washington U who took her on as a student (PhD ‘54).

While 4 kids were young, she taught at Georgetown before gaining a position at Carnegie’s Dept of Terrestrial Magnetism.🧵

They are Steven E. Koonin, a #physicist & author of a best-selling book that calls #ClimateScience “unsettled”; John Christy, an #atmospheric scientist who doubts the extent to which #human activity has caused #GlobalWarming; & Roy Spencer, a #meteorologist who believes that #clouds have had a greater influence on warming than #humans have [okay that last one is just bonkers].

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.

#OnThisDay Birth Anniversary of British #Physicist William Henry Bragg (1862). He uniquely shared a Nobel Prize with his son Lawrence Bragg - the 1915 Nobel Prize in Physics: "for their services in the analysis of crystal structure by means of X-rays".

British-Italian engineer Guglielmo Marconi obtained a patent for #Radio in London (1897).

James Clerk Maxwell (1831–1879) was born #OTD, 13 June. As a physicist, he ranks alongside Newton & Einstein (“He achieved greatness unequalled”—Max Planck; “I stand on the shoulders of Maxwell”—Albert Einstein).

Maxwell also wrote poetry: “Rigid Body Sings” is based on “Comin’ Through the Rye” by Robert Burns

In Memory of Edward Wilson, Who Repented of what was in his Mind to Write after Section
BY JAMES CLERK MAXWELL

Rigid Body (sings).

Gin a body meet a body
Flyin’ through the air,
Gin a body hit a body,
Will it fly? and where?
Ilka impact has its measure,
Ne’er a ane hae I,
Yet a’ the lads they measure me,
Or, at least, they try.

Gin a body meet a body
Altogether free,
How they travel afterwards
We do not always see.
Ilka problem has its method
By analytics high;
For me, I ken na ane o’ them,
But what the waur am I?

Happy birthday to #physicist James Clerk Maxwell (1831-1879)! He dreamt up his demon to deal with the very odd 2nd Law of Thermodynamics (which is not a law like others, and can not be derived from first priciples). It states that two bodies of different temperature brought together in a closed system will reach thermal equilibrium; or, you cannot use a cold thing to heat a hot thing; 🧵

Linocut print, 8”x10” on white washi paper, showing Maxwell’s demon in blue in a circle in the centre surrounded by red with the words “Maxwell’s” above and “Demon” below, arcing around the circle. My nimble-fingered demon resembles Maxwell, but with horns, extra-long fingers and enormous eyes to see and track particles and is using the cold blue region to warm the hot red region. In the blue region there are random slow moving particles denoted by dots with two tails. Carved into the red area are fast moving particles denoted by dots with three longer tail lines.

@aaronsher.bsky.social btw (shameless plug for #autaxys)... The problem with string theory and dark matter is not that they don't have a basis in #reality (which my #research is revealing) but they've become their own gods, whose adherents "worship" them by name.

Try asking a #physicist about an #information-theoretic #universe as a basis for #cosmology and you'll likely get a perjorative about #metaphysics or #philosophy (forgetting of course what the PhD in his title means)

Happy birthday #physicist Chien-shiung Wu (1912-1997), who came up with a truly beautiful experiment to test if the weak force conserves parity (whether beta decay would be the same if reflected in the mirror)! #linocut #sciart #physics #womenInSTEM #histsci #mastoArt spore.social/@minouette/1...
