A very few particles (out of 1000s) are named after scientists, eg the so called mu meson was called a Yukawa Meson, although it turned out to be a misnomer. Mu-meson was found to be a lepton, rather than a meson, as was thought by Yukawa and others.
Now called Muon it belongs in the same class that an electron belongs to, leptons, which are both Fermions. Hence initially thought to be a Boson (because all mesons would be bosons) the muon is actually a Fermion (all leptons are Fermions).
Should we say; initially muon was named after Bose, then correctly; after Fermi? That would be HOKUM. Right thing would be to say; it was named after Hideki Yukawa (wrongly as a meson or boson) then it has been named as muon which is now a Fermion. But its still named after Yukawa; given to a misnomer-correction. It can be called Yukawa-Lepton MUON (instead of Yukawa Meson Mu).
Nowhere Bose or Fermi have been the scientists after whom this particle has been named. Bose and Fermi are scientists after whom a principle of physics or nature has been named but not a particle. That would clear any mischievous air. More…
What we conveniently forget is what I just parenthesized as “Ethereal Relativism”. Before Einstein’s work, the ether was taken to be something that gives motion a sense of absoluteness. Ether was the absolute measure or reference of motion, therefore all motion seemed to be known as absolute. But its widely silent that Galileo and Newton worked in a frame-work of Physics or laws of nature where a frame of reference keeps motion relative, and not absolute: a concept known as Galilean Relativity.
In other words, if there is an object falling under gravity, in telling our story, we almost forgot that, there can also be a situation where, the relative motion of the falling object, can be studied; with or without the gravity acting on the object. In other words, still, the central question is to ask; did this single object fall faster or slower w.r.t. a situation when there is no gravity? Was it known or not, to Galileo, that, this object can be tested; to be falling faster in presence of the gravity causing object.
As we know today: Gravity causes objects to fall faster, it does not cause them to fall in the first place, between heavier and lighter objects it does not make any one of them to fall faster than the other and this is a force of central attraction to the proportion of; strength being as higher as the square of separation is, less.

It’s the birthday of James Joule, who was born in 1818 in Salford, England. Joule was a commercial brewer in Manchester. His work inspired an interest in physics and in the nature of energy. In a series of experiments, he demonstrated the convertibility of kinetic, thermal and electromagnetic energy. The SI energy unit, the joule, is named in his honor. More…
A hearty laugh that emancipates when we talk about his contributions. Many Many happy returns of the day to Soviet Scientist DR. Fock.
And scientists not only know sin or gays but also fock.
“And we don’t give a ** cos its your birthday”. Here is his contributions as enlisted by excerpts of Physics Today.
” It’s the birthday of Vladimir Fock, who was born in 1898 in St Petersburg, Russia. In 1916, while an undergraduate, Fock volunteered for the army. He survived World War I and went on to become a notable theoretical physicist. His principal contributions were in quantum mechanics and general relativity. Fock space, Fock states and the Hartree-Fock method all bear his name. Like Werner Heisenberg in Nazi Germany, Fock defended modern physics from ideological attacks – in Fock’s case, from the Communist Party of the Soviet Union in the 1930s. “
Above our moon, are seen the planet Jupiter with its largest 4 (out of 67? ) moons. The moons as discovered by Galileo were known as Callisto, IO, Europa, Ganymede. IO is volcanic with fatal levels of nuclear hazard on its environment while Europa is Icy. Today, the phenomenon of aura produced on Jupiter’s moon Europa, was explained briefly. Click on preceding link.
Galileo had observed the 4 largest moons, as named above, with his small telescope which is today known as Galileo, which was only the 2nd ever made telescope in the history of humanity, with about 30 times more resolving power than the first ever made by an engineer from Netherlands.
( — need to check on that specification of “30 x resolving power” in units of telescope resolving power of 1st )
But how magnetic a personality is Jupiter? Jupiter’s magnetism is bigger than Sun’s and earth’s. A fact that certainly excites its lovers.
This hubble image shows how plumes of water are sprayed into its own atmosphere by icy Europa which the armor Jupiter splits at the atomic level by throwing electric charges at the water molecules in a rapid manner by its magnetic arm. Just like we accelerate charges by magnetic field here on earth and make them split each other, the power of Jupiter’s darts are so high they split the water molecules into ions of H and O. That causes radiation in various hues of color, an aura captured by the Hubble telescope. More…
