In 1967, an atomic standard was adopted for second, the SI unit of time. One standard second is defined as the time taken for 9 192 631 770 periods of the radiation corresponding to unperturbed transition between hyperfine levels of the ground state of cesium - 133 atom. Atomic clocks are based on this. In atomic clocks , an error of one second occurs only in 5000 years. From 60 sec is 1 min from this 60 minutes is hour
Some of the major ones are : Astronaut Astrophysicist Astrobiologer Astrogeologist etc.
He considered Pluto to be an icy body and not a planet
This is a person who is mainly studying a branch of physics called Astrophysics. They deal with an analytically model and numerical simulation at work. Due to this being a large branch of physics an astrophysicist will dip their hands in the fields of aerospace engineering, mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and molecular physics To explain it in an easy statement its a person who studies the physics of stellar phenomena. Note: 'Astronomer' and 'Astrophysicist' can be used, pretty much, interchangeably.
Jocelyn Bell Burnell is a prominent astrophysicist from Northern Ireland. She is best known for her discovery of pulsars, which are rapidly rotating neutron stars that emit beams of electromagnetic radiation. Despite her groundbreaking discovery, she faced significant gender discrimination in the field of astrophysics.
France Anne Cordova is an American astrophysicist and former director of the National Science Foundation (NSF) from 2014 to 2020. She has also held various leadership positions in academia and research institutions throughout her career.
