The Eastchester Road Residence Complex, HP Pavilion dv7-2019ca Battery a 634-apartment complex comprising three 28 story apartment buildings, provides housing to all MD and PhD students (including some post-doctoral fellows) and their families.
Main article: Einstein’s unsuccessful investigations
Einstein conducted other investigations that were unsuccessful and abandoned. These pertain to force, superconductivity, HP Pavilion dv7-1250eb Battery gravitational waves, and other research. Please see the main article for details.
Collaboration with other scientists
The 1927 Solvay Conference in Brussels, a gathering of the world’s top physicists. Einstein in the centerHP Pavilion dv7-1250ed Battery.
In addition to long time collaborators Leopold Infeld, Nathan Rosen, Peter Bergmann and others, Einstein also had some one-shot collaborations with various scientists.
Einstein–de Haas experiment
Main article: Einstein–de Haas effectHP Pavilion dv7-1250eg Battery
Einstein and De Haas demonstrated that magnetization is due to the motion of electrons, nowadays known to be the spin. In order to show this, they reversed the magnetization in an iron bar suspended on a torsion pendulum. They confirmed that this leads the bar to rotate, because the electron’s angular momentum changes as the magnetization changesHP Pavilion dv7-1250en Battery. This experiment needed to be sensitive, because the angular momentum associated with electrons is small, but it definitively established that electron motion of some kind is responsible for magnetization.
Schrödinger gas model
Einstein suggested to Erwin Schrödinger that he might be able to reproduce the statistics of a Bose–Einstein gas by considering a box. HP Pavilion dv7-1250eo BatteryThen to each possible quantum motion of a particle in a box associate an independent harmonic oscillator. Quantizing these oscillators, each level will have an integer occupation number, which will be the number of particles in it.
This formulation is a form of second quantization, HP Pavilion dv7-1250ep Batterybut it predates modern quantum mechanics. Erwin Schrödinger applied this to derive the thermodynamic properties of a semiclassical ideal gas. Schrödinger urged Einstein to add his name as co-author, although Einstein declined the invitation.
