This year is the International Year of Quantum Science and Technology. Proclaimed by the UN, it celebrates the centenary of ...

Alpha-particle scattering experiment; Rutherford's model of atom; Bohr model of hydrogen atom, Expression for radius of nth possible orbit, velocity and energy of electron in nth orbit ...

The hydrogen atom consists of a single proton of positive charge and a single electron of negative charge, orbiting around the proton. All atoms and ions having a single orbiting electron are ...

With this simple assumption — each atom emitting or absorbing only whole multiples of a tiny energy unit — Planck’s formula matched the data perfectly. This launched the quantum age. In the years that ...

A recent study in Advanced Materials Interfaces examined γ’-Fe₄N nitride layers, formed on iron, as a potential barrier ...

In physics, Schrödinger's cat is a thought experiment in which a cat is trapped in a box with a particle that has a 50-50 ...

An international research team has successfully achieved single-molecule spectroscopic observation of hydrogen (H2) and ...

Quantum superposition states created at warmer temperatures, questioning the need for extreme cold in order to work with ...

Ever support a policy but feel uneasy about it? Here's my take on how psychology—and Schrödinger’s cat—can help you make ...
