[PAR] [TLE] Luis Walter Alvarez [SEP] Luis Walter Alvarez (June 13, 1911 – September 1, 1988) was an American experimental physicist, inventor, and professor who was awarded the Nobel Prize in Physics in 1968.  The American Journal of Physics commented, "Luis Alvarez was one of the most brilliant and productive experimental physicists of the twentieth century." [PAR] [TLE] 3581 Alvarez [SEP] 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.
