The father of scientist Walter Alvarez recived a Nobel Prize in Physics in what year?
3581 Alvarez 3581 Alvarez (1985 HC) is a Mars-crossing asteroid discovered on April 23, 1985, by Shoemaker, C. and Shoemaker, E. at Palomar. Based upon lightcurve data, it has a synodic rotation period of  hours with an amplitude variation of in magnitude. With a diameter of ~14 km, it is one of the largest Mars-crossing asteroids. However, due to the high inclination of its orbit, it never actually passes through the orbit of Mars since at perihelion it is well away from the plane of Mars' orbit. The asteroid is named after planetary scientist Walter Alvarez and his Nobel-prize winning father, physicist Luis Alvarez.
C. V. Raman Sir Chandrasekhara Venkata Raman (7 November 188821 November 1970) was an Indian physicist born in the former Madras Province in India presently called as Tamil Nadu, who carried out ground-breaking work in the field of light scattering, which earned him the 1930 Nobel Prize for Physics. He discovered that when light traverses a transparent material, some of the deflected light changes wavelength. This phenomenon, subsequently known as Raman scattering, results from the Raman effect. In 1954, India honoured him with its highest civilian award, the Bharat Ratna.
