On This Day in 1960, physicist Theodore Maiman fired the first functioning laser at Hughes Research Laboratories using a synthetic ruby crystal. Unlike previous attempts at light amplification, Maiman’s device achieved coherent, monochromatic, and highly directional light... the holy trinity of laser physics. It worked by triggering stimulated emission in excited chromium ions, creating the first practical population inversion. That precise beam has since revolutionized fibre optics, barcode scanners, semiconductor lithography, laser surgery, and quantum computing. Not bad for something that, according to early critics, was “a solution looking for a problem.” #OnThisDay #OTD #Tech #Photonics #LaserEngineering

“How the world began is a problem for the physicist and the astronomer [...] How life began is a problem for the biologist [...]. Why the world began, why life began, on the other hand, I think are pseudo-questions.” —W.V.O. Quine on the nature of philosophy

🌌 DID A UNIVERSE EXIST BEFORE THE BIG BANG? A Nobel Prize-winning physicist believes our universe may not be the first one. According to the theory, an earlier universe existed before the Big Bang, and tiny clues from it could still be visible in space today. If true, the Big Bang may have been a new beginning—not the absolute start of everything. What if the night sky is hiding messages from a universe older than our own? Source:

I'm back and it's time to cook some frauds, starting with fake physicist Avi Loeb and his knew 'UAP advsory board.' Then Jeremy Corbell and fake NHI biologics file. Then I'll explain what they're really hiding. Disclosure DUMP, LIVE at 5pm CST youtube.com/live/SzcyfY_dv80…

Before the world knew Satyendra Nath Bose as the physicist whose ideas would reshape quantum mechanics, he was a young man teaching the children of workers in the narrow lanes of Maniktola. Long before the famous letter to Einstein. Long before photons, Bose-Einstein statistics & a new chapter in modern physics. S.N. Bose was among a group of young students who spent their evenings running classes at the Working Men's Institute, a night school for working-class children. The Institute operated from Keshab Academy on Maniktola Street & had been founded by associates of Sri Aurobindo Ghosh & Barin Ghosh during a period when nationalism, education & social reform often walked hand in hand. The school's president was the renowned Presidency College mathematics professor D.N. Mallik. Among the young volunteers conducting classes were Nirendranath Roy, Satyen Bose, Girijapati Bhattacharyya, Pashupati Bhattacharyya & Harish Sinha. They continued teaching there until they completed their B.Sc. examinations. History remembers Bose for changing our understanding of the universe. But before he taught the world how photons behave, he was teaching ordinary children who simply wanted a chance at education.

13 June 1831: the great physicist and mathematician James Clerk Maxwell was born. Once Einstein said: "There would be no modern physics without Maxwell’s electromagnetic equations: I owe more to Maxwell than to anyone.” In his office in Princeton there were three portraits: Newton, Faraday, Maxwell. Maxwell did revolutionary work on electricity, magnetism, optics and on the kinetic theory of gases. Specifically, he developed the first modern theory of electromagnetism by unifying, through the so-called Maxwell equations, previous observations, experiments and equations of this branch of physics. In his work A Dynamical Theory of the Electromagnetic Field (1865), he proposed that the electromagnetic field, as described by his equations, was the cause of electrical, magnetic, and optical phenomena. His unified model for electromagnetism is considered the second great unification of physics, after that brought about by Newton. (royalsocietypublishing.org/d…) Today he is recognised as one of three most important scientists of an era spanning some 300 years, which began with Newton and closed with Einstein. Without their revolutionary works we wouldn't have either the civilisation that we have or the ability to understand the way the world works, and what we should do to make it better. On the centenary of Maxwell's bday, Einstein described his work as the "most profound and the most fruitful that physics has experienced since the time of Newton". In Einstein’s view, in fact, Maxwell's equations were pivotal to the development of his own theory of relativity, first published in 1905. Richard Feynman said of him "there can be little doubt that the most significant event of the 19th century will be judged as Maxwell’s discovery of the laws of electrodynamics". Maxwell passed away at age of only 48. Ten years after his death, Hertz definitely proved what Maxwell had theorised.
