On this day in science Erwin Schrödinger was born Austrian theoretical physicist who shared the 1933 Nobel Prize for Physics with the British physicist P.A.M. Dirac. Erwin Schrödinger took Louis de Broglie's concept of atomic particles as having wave-like properties, and modified the earlier Bohr model of the atom to accommodate the wave nature of the electrons. This made a major contribution to the development of quantum mechanics. Schrödinger realized the possible orbits of an electron would be confined to those in which its matter waves close in an exact number of wavelengths. This condition, similar to a standing wave, would account for only certain orbits being possible, and none possible in between them. This provided an explanation for discrete lines in the spectrum of excited atoms. #science #scienceandtechnology #physics #chemistry #pharmacy #quantum #infographic via Compound Interest | Chemistry infographics

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

On this day in science Max Karl Ernst Ludwig Planck was born Max Planck was a German theoretical physicist who studied at Munich and Berlin, where he studied under Helmholtz, Clausius and Kirchhoff and subsequently joined the faculty. He became professor of theoretical physics (1889-1926). His work on the law of thermodynamics and the distribution of radiation from a black body led him to abandon classical Newtonian principles and introduce the quantum theory (1900), for which he was awarded the Nobel Prize for Physics in 1918. This assumes that energy is not infinitely subdivisible, but ultimately exists as discrete amounts he called quanta (Latin, “how much”). Further, the energy carried by a quantum depends in direct proportion to the frequency of its source radiation. #science #scienceandtechnology #physics #sciencecommunication #quantum #quantumphysics #nobelprize #onthisday #chemistry

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

On this day in science Jerome Isaac Friedman was born Friedman an American physicist who, together with Richard E. Taylor and Henry W. Kendall, received the Nobel Prize for Physics in 1990 for their joint experimental confirmation of the fundamental particles known as quarks. But what are quarks. Quarks are elementary particles. Like the electron, they are not made up of any other particles. Quarks associate with one another via the strong force to make up protons and neutrons, in much the same way that the latter particles combine in various proportions to make up atomic nuclei. Quoting Friedman "The quarks are moving around so fast that they give us weight. As Einstein pointed out in E=mc2, energy is equivalent to mass." About half of our mass comes from the motion of the quarks, and about half from the force field that holds the quarks together in the proton." #science #scienceandtechnology #Physics #sciencecommunication #scienceandtechnology #chemical #infographic

The origin of mass is a topic that has been front and center in particle physics for several decades and is featured in the popular scientific press with varying regularity. Whenever particle physicists explain their scientific discipline and their enthusiasm for fundamental physics to the general public, you might hear statements such as “The Higgs field gives all other fundamental particles mass.” Discussions of this so-called Higgs mechanism spiked dramatically in 2012, when researchers at CERN announced the discovery of the Higgs boson, the fundamental particle associated to the Higgs field.

Prof. Sabine Hossenfelder talks about the impact of #philosophy on #physics in this video from The Institute of Art and Ideas. I was particularly intrigued about the impact of looking for #simplicity and #singularity on progressing physics. Physicists have been looking for a "theory of everything" for decades that will unify the four fundamental forces of nature. Maybe #quantizing #gravity is just not possible because #nature does not work that way. But then again the #StandardModel of #particlephyics describes all observable matter (5% of the #universe), a great achievement. Standard Model is not simple and does not explain everything about visible matter. Recent results from the LHCb experiment CERN and Muon g-2 experiment at Fermilab suggest the existence of a fifth fundamental force of nature. The #StandardModel also does not explain the #matter-#antimatter discrepancy and the three flavors of matter. The implications being maybe simplifying is not the solution. Can somebody point to some discussions, articles or books that address this question?
