1933 - October 17 – Scientist Albert Einstein arrives in the United States where he settles permanently as a refugee from Nazi Germany and takes up a position at the Institute for Advanced Study, Princeton, New Jersey.
In October 1933, Albert Einstein's arrival in the United States marked a pivotal moment both in his personal life and in the realm of scientific history. Fleeing Nazi Germany amid rising persecution of Jewish intellectuals, Einstein, already renowned for his groundbreaking theories in physics, sought refuge in America. His decision to settle permanently in the U.S. was influenced by the political climate in Europe and the opportunity to continue his work unhindered by the increasingly oppressive regime.
Upon arriving in the U.S., Einstein accepted a position at the Institute for Advanced Study in Princeton, New Jersey, which would become his academic home for the remainder of his career. This move not only secured his safety but also solidified Princeton's reputation as a leading center for theoretical physics.

1940 - April - 1st electron microscope demonstrated (RCA), Philadelphia, Pennsylvania, USA

The microwave oven was invented accidentally in 1945 by Percy Spencer, a Raytheon engineer. While testing a magnetron, he noticed microwaves melted a candy bar in his pocket. Experimenting further, he discovered microwaves could cook food quickly. Raytheon patented the process, and by 1947, they built the first commercial microwave oven, called the 'Radarange.' Initially used in commercial settings, microwaves becomes affordable for home use by the 1960s and 1970s, revolutionizing cooking.
