Yates says Atlanta has come a long way since the '70s. But Silicon Valley has several key advantages: easy access to capital and a network of seasoned entrepreneurs. And, Yates says: Maybe this is a cultural difference in the rest of the world versus the Valley, but it's the idea that in the Valley, it's OK to fail.
The angular frequency is measured in radians per second. The inverse of the period is the frequency f = 1/T. The frequency f = 1/T = Ï/2Ï of the motion gives the number of complete oscillations per unit time. It is measured in units of Hertz, (1 Hz = 1/s).
The metric unit (in SI) for time is the second (s). The official definition of second is now (after CIPM): the duration of 9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium-133 atom; this definition refers to a caesium atom at rest at a temperature of 0 K.
