It is well known that 45 is the optimal angle to send a projectile, to achieve the maximal range, R (on flat ground). Yet, the best shot putters release at much less than 45 instead. The resolution to this “puzzle” was traced to the landing site being lower than the height of release [Lichtenberg and Wills, AJP, 1978]. A standard problem, its solution typically involves setting to zero the...
A spool of ribbon is placed on a rough horizontal table. The ribbon is pulled so that it makes an angle relative to the table, where 0 degrees means the ribbon is unwinding from the bottom of the inner axle of the spool, 90 degrees corresponds to the ribbon being pulled straight up into the air, and 180 degrees implies the string is unwinding from the top of the inner axle. Suppose the spool...
Einstein predicted the presence of gravitational waves, ripples of spacetime. In 2015, LIGO detected these waves from colliding black holes for the first time and gravitational-wave astronomy has begun. In this talk, I will give a very brief overview of the current status of gravitational-wave observations and what comes next.
