This Day in Science History — (Sept 27) In paper, Einstein introduced the mass-energy equivalence. Although E = mc² does not appear, the famous equation is present implicitly in the sentence "If a body gives off the energy L in the form of radiation, its mass diminishes by L/c²

Dear students, pay attention here! Do you know the real meaning of education? Read the quote in the image. It is attributed to the genius #AlbertEinstein. It emphasizes that the true purpose of education is to develop critical thinking, problem-solving skills, not memorising.

It's the death anniversary of "Karl Manne Georg Siegbahn" — — (Scientist of the Day - 26 September) He won the 1924 Nobel Prize for his pioneer works in X-ray spectroscopy. His precision measurements drove many developments in quantum theory and atomic physics.

Let me know how many are better here! Keep following us & share it with your friends/students.

It's death anniversary of #JohannHeinrichLambert, the man who provided the first rigorous proof that π is irrational — (Scientist of the Day - 25 September) He made important contributions to the subjects of mathematics, physics, philosophy, astronomy and map projections.

Must Know The Facts on The Nobel Prize in Physics — — Look at the infographics. Additionally :- — 47 physics prizes have been given to one laureate only. — 33 physics prizes have been shared by two laureates. — 38 physics prizes have been shared between three laureates.

Happy birthday to you #IanNicholasStewart, the man who is best known for his 'book' on 17 equations that changed the world — Stewart is Emeritus Professor of Mathematics at the University of Warwick, England. He is a popular-science & science-fiction writer. Today he turns 80.

There are many great figures who established the science of nature i.e. PHYSICS. Based on their works (contribution), here are those great minds who are considered the father of (different - different) physics. Keep following us & share it.

It's the birthday of #ArmandHippolyteLouisFizeau, the man who is best known for being the first to develop a reliable experimental method of determining the speed of light on the Earth — (Scientist of the Day - 23 September)

Professor #RichardFeynman, one of the greatest scientists of all time. For his contributions to the development of quantum electrodynamics, he was awarded the 1965 Nobel Prize in Physics (with Julian Schwinger and Shin'ichirō Tomonaga). Keep following us and share it.

Today , September 22, at 14:20 hrs EDT / 18:20 hrs GMT / 23:50 hrs IST, day and night stand in perfect balance. Celebrate the turning of the seasons — embrace the LIGHT and the DARK. Happy Autumnal Equinox 2025!

It's the birthday of #MichaelFaraday, one of the most influential scientists in history — (Scientist of the Day - 22 September) He made the discoveries upon which most of the 20th-century technology is based. The SI unit of capacitance is named in his honour: the farad.

Stephen Hawking Was Right! In 1971, professor Stephen Hawking proposed the Black Hole Area Theorem — "the total surface area of a black hole's event horizon can never decrease over time". The theorem was observationally confirmed by LIGO and Virgo observatories.

How to Understand EFE - Part - 2 In part-1 (published on Sept 13), you knew a standard form of EFE. Let me introduce you today to the mathematics of this equation (terminology). Mathematically, it is a monster. The shown equation is original form that Einstein published in 1917

Did you know — physicists use mathematical models to represent physical phenomena. These models are not the full reality but abstract representations that highlight specific mathematical relationships and allow for predictions.
