They were also the first animals to safely return from space. [55] Albert II, a rhesus monkey, became the first mammal in space aboard a U.S. V-2 rocket on June 14, 1949, and died on reentry due to a parachute failure. The first dogs in space were launched 22 July 1951 aboard a Soviet R-1V. "Tsygin" and "Dezik" reached a height of 100 km (62 mi ...
The programme carried out six crewed spaceflights between 1961 and 1963. The program was the first program to put humans into space, with Yuri Gagarin becoming the first man in space on April 12, 1961, aboard the Vostok 1. [79] Gherman Titov became the first person to stay in orbit for a full day on August 7, 1961, aboard the Vostok 2. [80]
Historically, physics emerged from the scientific revolution of the 17th century, grew rapidly in the 19th century, then was transformed by a series of discoveries in the 20th century. Physics today may be divided loosely into classical physics and modern physics .
1876 – William Kingdon Clifford suggests that the motion of matter may be due to changes in the geometry of space. [24] 1882 – Simon Newcomb observes a 43 arcsecond per century excess precession of Mercury's orbit. 1884 – William Thomson (Lord Kelvin) lectures on the issues with the wave theory of light with regards to the luminiferous ...
A golden age of physics began with the simultaneous discovery of the principle of the conservation of energy in the mid-19th century. [7] [8] A golden age of physics was the years 1925 to 1927. [9] The golden age of nonlinear physics was the period from 1950 to 1970, encompassing the Fermi–Pasta–Ulam–Tsingou problem and others. [10]
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
Vladimir Chelomey (1914–1984), USSR – First space station ; Joyce Chen (1917–1994), China – stir fry pan; Pavel Cherenkov (1904–1990), USSR – Cherenkov detector; Evgeniy Chertovsky (1902–1961), Russia – pressure suit; Alicia Chong Rodriguez – American engineer and inventor; Ward Christensen (born 1945), U.S. – Bulletin board ...
