"My mentality is that of a samurai. I would rather commit seppuku than fail."
Surely, Elon Musk, in his vast and titanic career has shown the world what a man can be capable of if he dreams and executes it with adherence. His vision has led to the creations of Tesla, SpaceX, Hyperloop concept and many more that have completely revolutionized our own reality. Elon, Knowledgekart wishes you a very Happy Birthday and wishes you to dream big and innovate bigger.

The man behind the 'Zeeman effect'.

Pieter Zeeman, born on 25 May 1865, was awarded the 1902 Nobel Prize in Physics together with Hendrik Lorentz. In 1892 Lorentz presented his electron theory, which posited that in matter there are charged particles, electrons, that conduct electric current and whose oscillations give rise to light. Lorentz's electron theory could explain Zeeman's discovery that the spectral lines corresponding to different wavelengths split up into several lines under the influence of a magnetic field, also called the 'Zeeman effect'.

Zeeman worked as a professor as well as Director of the Physics Laboratory at the University of Amsterdam / Universiteit van Amsterdam. In 1923 a new laboratory, specially erected for him, was put at his disposal, a prominent feature being a concrete block weighing a quarter of a million kilograms, erected free from the floor, as a suitable platform for vibration-free experiments. The institute became known as the Zeeman Laboratory of Amsterdam University. Many world-famous scientists visited Zeeman there or worked with him for some time.

Its Happy Birthday today of our beloved Physicist

[ SIR ALBERT EINSTEIN ]

Albert Einstein 14 March 1879 – 18 April 1955) was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).

While best known for his mass–energy equivalence formula E = mc^2 (which has been dubbed "the world's most famous equation")

he received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect".

The latter was pivotal in establishing quantum theory.

The Summer Institute is a new immersive two-week creative writing and cultural exchange program held in Iowa City, Iowa, U.S., a UNESCO City of Literature, for participants age 18-22 from Pakistan, India, and the U.S. Students from all disciplines – the arts, humanities, sciences, and everything in between – are welcome to apply! This program is free for selected participants, and will focus on creative writing and the power of narrative. click here to apply http://iwp.uiowa.edu/programs/summer-institute/2019

National Science Day is celebrated every year on February 28 to commemorate the discovery of Raman Effect by CV Raman on this day in 1928. The discovery won him the Nobel prize in physics a couple of years later.
