When it comes to the smallest components of our universe, our usual understanding of how the world works ceases to apply. We have entered the realm of quantum physics. For a long time, many quantum phenomena could only be examined theoretically. Starting in the late 1970s, David Wineland designed ingenious experiments to study quantum phenomena when matter and light interact. Using electric fields, he successfully captured electrically charged atoms, or ions, in a kind of trap and studied them with the help of small packets of light, or photons. Born on this day in 1944, Wineland was awarded the 2012 Nobel Prize in Physics. Learn more about his work: https://bit.ly/3SunYF2 #NobelPrize

Dr. Simeon Mistakidis, assistant professor of physics, is one of the authors of an article in the prestigious journal nature physics that was published recently. The title of the paper is "Universality class of a spinor Bose–Einstein condensate far from equilibrium". Link in comments. The image shows a snapshot of the distribution of the population imbalance between different modes of an atomic spinor gas. The gas of atoms evolves in time after crossing a quantum phase transition boundary featuring universal characteristics.

Neutrons, when plucked from the nucleus of atoms, become unstable and decay after some time. Physicists know that these unstable neutrons die after about 14 minutes, but they cannot pinpoint the exact seconds in which the neutrons last, even as today’s experiments are at their most precise. Dr. Denny Lane Sombillo of the UP Diliman College of Science National Institute of Physics (UPD-CS NIP) thinks the explanation may lie in how time behaves at a quantum level.

J.J. Thomson, then he was a British physicist born on December 18, 1856, and passed away on August 30, 1940. J.J. Thomson is best known for his discovery of the electron, which he identified as a fundamental particle of matter in 1897. This discovery revolutionized our understanding of atomic structure and laid the foundation for modern physics. Thomson's work earned him the Nobel Prize in Physics in 1906. He also made significant contributions to the study of the nature of cathode rays, isotopes, and the development of mass spectrometry. #JJThomson#ElectronDiscovery#AtomicTheory#PhysicsPioneer#Scientist #ParticlePhysics#AtomicStructure

Particle physics is always fascinating and attractive study.

 Thomson devised new experiment in 1897 to discover the #electron. A charged #particle will curve as it moves through an electric field. Since the gas traces remaining in the tube may affect this experiment, he managed to extract nearly all of the gas from the tube, and the cathode rays did bend when an electric field was applied. This shows that cathode rays are charges of negative electricity carried by particles of matter. The mass-to-charge ratio for cathode rays turned out to be over one thousand times smaller than that of a charged hydrogen atom. It was shown later that the cathode rays were particles with a mass far smaller than that of any atom.

Erwin Schrödinger is a great name we come across while studying Chemistry... especially Quantum chemistry. What he started with wave mechanics for microscopic particle and gave his famous wave equation... solving which still haunts chemists and theorists for complicated atomic and molecular systems. So many computational models still being developed to solve the equation with increasing accuracy and more perfect approximations... but still there are "approximations" only! The legacy of Schrödinger is indeed still evergreen and never-ending and yielding great minds throughout the world to work on it! Nothing wrong to say that future of chemistry is looking upon future of quantum!

"I was attracted to particle physics because of three famous names, Nishina, Tomonaga and Yukawa, who were the founders of particle physics in Japan," said physics laureate Yoichiro Nambu, who gave us a better understanding of elementary particles and their interactions. Nambu discovered the mechanism of spontaneous broken symmetry in subatomic physics. This earned him the 2008 Nobel Prize in Physics. Learn more: https://bit.ly/3F4uIjI

1892 Sir Edward Victor Appleton (6 Sep 1892; 21 Apr 1965) was a English physicist who won the 1947 Nobel Prize for Physics for his discovery of the Appleton layer of the ionosphere. From 1919, he devoted himself to scientific problems in atmospheric physics, using mainly radio techniques. He proved the existence of the ionosphere, and found a layer 60 miles above the ground that reflected radio waves. In 1926, he found another layer 150 miles above ground, higher than the Heaviside Layer, electrically stronger, and able to reflect short waves round the earth. This Appleton layer is a dependable reflector of radio waves and more useful in communication than other ionospheric layers that reflect radio waves sporadically, depending upon temperature and time of day.*TIS #onthisdayinmath
