in 1947First flight of the B-45 Tornado strategic bomber.
The North American B-45 Tornado was the United States Air Force's first operational jet bomber, and the first jet aircraft to be refueled in the air. The B-45 was an important part of the United States's nuclear deterrent for several years in the early 1950s, but was rapidly succeeded by the Boeing B-47 Stratojet.

in 1958The United States launches the Vanguard 1 satellite.
Vanguard 1 was the fourth artificial Earth satellite launched and the first satellite to be solar powered. Although communication with it was lost in 1964, it remains the oldest manmade satellite still in orbit. It was designed to test the launch capabilities of a three-stage launch vehicle as a part of Project Vanguard, and the effects of the environment on a satellite and its systems in Earth orbit. It also was used to obtain geodetic measurements through orbit analysis.
Mount Agung erupted on Bali.
Mount Agung or Gunung Agung is a mountain in Bali, Indonesia. This stratovolcano is the highest point on the island. It dominates the surrounding area influencing the climate.

Daniel Bernoulli was a Dutch-Swiss mathematician and was one of the many prominent mathematicians in the Bernoulli family. He is particularly remembered for his applications of mathematics to mechanics, especially fluid mechanics, and for his pioneering work in probability and statistics.
