Austrian mathematician and physicist (1803–1853)

factor 1∕√(1−𝑣²∕𝑐²) in special relativity expressing how much the measurements of time, length etc. change for a moving object

Loss of angular momentum in orbiting dust grains due to stellar radiation

Phenomenon in physics

Scientific phenomenon

spectroscopic phenomenon observed when either an eclipsing binary's secondary star or an extrasolar planet is seen to transit across the face of the primary or parent star.

A device used to make non-contact vibration measurement of a surface using a beam of light.

experiment testing the contribution of relativistic time dilation to the Doppler shift of light

laser cooling technique

optical method of measuring fluid flow

Formula for measuring astronomical objects

effect in cosmology where the spatial distribution of galaxies as a function of redshift appears squashed due to Doppler shift from peculiar velocities on top of cosmological redshift
