Maria Skłodowska-Curie and Henri Poincaré discussing at the 1911 Solvay Conference held in Brussels. The subject of the conference was 'Radiation and the Quanta.'

The principal aim of mathematical education is to develop certain faculties of the mind, and among these intuition is not the least precious. It is through it that the mathematical world remains in touch with the real world, and even if pure mathematics could do without it, we…

The Miller-Urey experiment was a groundbreaking scientific study conducted in 1952 by Stanley Miller under the supervision of Harold Urey at the University of Chicago. The experiment was designed to test the chemical origins of life under conditions thought to resemble those of…

Chandrasekhar limit equation calculates the maximum mass M(limit) of a stable white dwarf star, above which it would collapse under its own gravity, leading to a neutron star or black hole. μₑ ​is the mean molecular weight per electron and M⊙ ​is the solar mass.

Berry Phase (Geometric Phase) in Quantum Mechanics ✍️

This equation describes the Berry phase, a phase difference acquired over the course of a cycle, when the system is subjected to cyclic adiabatic processes. Here, ∣n(R)⟩ are the eigenstates of the Hamiltonian depending on…

Trofim Lysenko was a Soviet agronomist whose discredited theories of genetics were politically supported by Joseph Stalin. Lysenko rejected Mendelian genetics and natural selection, promoting instead the idea that environmental change could directly affect genetic traits. His…

Knowledge of the fact differs from knowledge of the reason for the fact.

- Aristotle (384 BC – 322 BC)

We must be clear that when it comes to atoms, language can be used only as in poetry. The poet, too, is not nearly so concerned with describing facts as with creating images and establishing mental connections.

- Niels Bohr (1885 - 1962)
