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.

Happy birthday to German-American theoretical #physicist Maria Goeppert Mayer (1906-1972), the 2nd woman to win the Nobel Prize for #physics. 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” (a term coined by Wigner):
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
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;

Happy birthday #physicist Chien-shiung Wu (1912-1997), who came up with a truly beautiful experiment to test whether the weak force conserves parity (whether beta decay would be the same if reflected in the mirror)! In my print on the left I show Wu in her lab & a schematic diagram of her experiment. On the right I show her reflection, as in the mirror, & the mirror reflection of the experimental set-up & the shocking result, 1/n
Happy birthday to British #engineer, #mathematician, #physicist & #inventor Hertha Ayrton (1854-1923). I’ve shown her in my #linocut with a diagram of the dividers from her 1st of 26 (!) patents, one of her diagrams about the origin & growth of ripple marks & one of her diagrams of an electric arc lamp (a subject on which she literally wrote the textbook).
Born Phoebe Sarah Marks, she was the 3rd of 8 children
Born on this day: #physicist J. R. Oppenheimer (1904-1967). While best remembered for his role in the Manhattan Project, he was a giant of 20th century theoretical physics, nominated for a Nobel 3 times.
In 1927 he & Max Born greatly simplified how we predict electrons behaviour within atoms. The Born-Oppenheimer or adiabatic approximation is based on the observation that electrons are 1000s times lighter than nuclei, 1/n

Happy birthday to French mathematician, physicist and philosopher Marie-Sophie Germain (1776 – 1831), known as Sophie. She taught herself mathematics using books in her father’s library and by corresponding with leading mathematicians of her day, including Lagrange, Legendre and Gauss, initially using the pseudonym Monsieur LeBlanc. 1/n

So everything ultimately when you zoom in close enough is just physics. Matter is made of atoms and atoms are made of particles and particles are just bits of energy moving around excitedly. I might have missed a few layers but good enough for a layperson discussion.
I know there have been experiments to cool things to absolute zero, and I know we've gotten pretty close but not quite.
But what would happen at absolute zero, or do we even know for certain? If those bits of energy stop moving, do they cease to exist? Would the macro object just poof?
