March 29 in Physics History - Births – Physicists born on March 29
Harold Spencer Jones (29 Mar 1890 - 3 Nov 1960)
He was an English astronomer and 10th astronomer royal of England. He showed that the small enduring in the apparent motion of the planets is due to Earth’s irregular rotation. He also worked on motions and parallaxes and improved timekeeping and knowledge of the rotation of Earth.
James E. Hansen (Born on 29 Mar 1941)
He is an American atmospheric physicist who is directing the program on climate change at Columbia University. He started there as a research associate in 1969. He was also the director of the NASA Goddard Institute for Space studies. He is known as the most influential speaker on climate change.

Francesco Zantedeschi (20 Aug 1797 - 29 Mar 1873)
He was an Italian physicist and priest who was the first to recognize the marked absorption by the atmosphere of the yellow, red, and green light. He published papers on the production of electric currents by the movements of a magnet. He also experimented on the repulsion of flames by a strong magnetic field.

Asteroid 4 Vesta Discovery
4 Vesta is the brightest asteroid on record visible to the naked eye. It was first observed by Heinrich Wilhelm Olbers on this day in 1807. Its diameter is about 525-km and its rotation period is of 5.34 hours. Its surface was found to be what we call terrestrial. It once had a molten interior.
First Picture of Mercury
On this day, Mariner 10 took the first picture of Mercury in 1974. It was the first spacecraft to use the gravitational pull of one planet to reach another planet. It was also the first one to use solar wind as a means of locomotion. Mariner 10 found a thin atmosphere and a magnetic field on Mercury.
