Galileo showed convincingly that heavy objects fell no faster that light ones. ... If an iron ball was pulled down with a much greater force than a wooden one of the same size, why didn't it fall any faster? ... 1) It is harder to lift. ... It is the fact that the loaded wagon has a greater mass that gives it a larger inertia , a larger tendency to oppose any change in its state of rest or of constant motion in a straight line. ... One important quantity was the body mass of the astronauts. ...

In 1848 the Swiss astronomer Johann Rudolph Wolf introduced a daily measure- ment of sunspot number. His method, which is still used today, counts the total number of spots visible on the face of the sun and the number of groups into which they cluster, because neither quantity alone satisfactorily meas- ures sunspot activity. An observer computes a daily sunspot number by multiplying the number of groups he sees by ten and then adding this product to his total count of in- dividual spots. ...

... Let us first find out which way -- rise in spectral resolution with some loss in the S/N ratio or increase in the S/N ratio with a fixed spectral resolution -- is better for the purpose of reduction of equivalent width determination errors. ... N -- number of counts for 1 ? ... line equivalent width, . ... Thus if the spectral resolution is managed to be increased (i.e. to decrease )without loss in the number of counts falling at 1 ?, the equivalent width measurement error is then proportional to . ...

The temperature dependence of the magnetic field penetration depth lambda ( T ) is determined down to 0.2 T c by the ac-susceptibility measurements on the Rb 3 C 60 fine powder with small, about 1 K, variation in the grains' superconducting transition temperatures. The lambda ( T ) temperature dependence is exponential at low temperatures, which allows us to determine the energy gap Delta 0 =1.7 k B T c . ...
