The Jeans mass is named after the British physicist Sir James Jeans, who considered the process of gravitational collapse within a gaseous cloud. He was able to show that, under appropriate conditions, a cloud, or part of one, would become unstable and begin to collapse when it lacked sufficient gaseous pressure support to balance the force of gravity.
Sir James Hopwood Jeans OM FRS [1] (11 September 1877 – 16 September 1946 [2]) was an English physicist, mathematician and an astronomer.He served as a secretary of the Royal Society from 1919 to 1929, and was the president of the Royal Astronomical Society from 1925 to 1927, and won its Gold Medal.

The founder, Cecil Schumacher, was a Cosworth transmission engineer who was recruited from Borg Warner to lead the design team to adapt the Hobbs transmission (which he had worked on) to handle the Cosworth DFV's power.
Radio-controlled cars, or RC cars for short, [1] are miniature vehicles (cars, vans, buses, buggies, etc.) controlled via radio.. Nitro powered models use glow plug engines, small internal combustion engines fuelled by a special mixture of nitromethane, methanol, and oil (in most cases a blend of castor oil and synthetic oil).
Graupner was founded by Johannes Graupner in Stuttgart in 1930 as a scale model manufacturer. Two years later, the company was moved to Kirchheim unter Teck. In 1935, the first glider model was introduced, and in 1938, the first building plans and materials for ship scale modeling were produced.
The absolute best jeans for flat butts strike a magical feeling in your heart by lifting your bum and turning those plywood cheeks into a perky apple bottom. They’re comfortable, yet supportive, an
1:10 scale radio-controlled car (Saab Sonett II)A radio-controlled model (or RC model) is a model that is steerable with the use of radio control (RC). All types of model vehicles have had RC systems installed in them, including ground vehicles, boats, planes, helicopters and even submarines and scale railway locomotives.
