Today on 21st of April 1774, Jean-Baptiste Biot was born. He was a French physicist, astronomer, and mathematician. He was known for Biot–Savart law and studied the polarization of light.
Polarization (also polarisation) is a property applying to transverse waves that specify the geometrical orientation of the oscillations.
Biot–Savart law is an equation describing the magnetic field generated by a stationary electric current. It relates the magnetic field to the magnitude, direction, length, and proximity of the electric current.
