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.

The most basic gravitational stability analysis is the Jeans criteria, which addresses the balance between self-gravity and thermal pressure in a gas. In terms of the two above stability conditions, the system is stable if: i) thermal pressure balances the force of gravity, and ii) if the system is compressed slightly, the outward pressure ...
In addition to that immediate boost, the company initially expected to capture at least $500 million in annual cost and capital savings within the first full year following the deal.
If the thermal motion of the electrons is ignored, it is possible to show that the charge density oscillates at the plasma frequency =, [/] (), =, [/] (), where is the number density of electrons, is the electric charge, is the effective mass of the electron, and is the permittivity of free space.
Once the bladder is about half full, nerve receptors tell the brain it’s time to pee, and the brain tells your bladder to hold it until a socially acceptable time to urinate, Kim said. That’s ...
New York Giants quarterback Tommy DeVito is officially inactive for Thursday's Thanksgiving game against the Dallas Cowboys (4:25 p.m. ET, Fox) due to a forearm injury.
