F = (...Newton's second law can be expressed as <br />F = (d / dt) (mv) <br />if we take into account the work of Lorentz and consider the change of mass according to his transformation's group.<br />Then:<br /><br />F = m (dv / dt) + (dm / dt) v = ma + (dm / dt) v<br /><br />With this, we see that an employee working very hard (in a given time) may be having a negative mass change (the approach of 6 o’clock syndrome or he is starting to get tired) and so, he is diminishing in productivity.<br />And, conversely, an employee suffering a hangover may, indeed, have a positive mass change (two Alka Seltzer's) and start working productively.<br /><br />Physics is the way to go!HGDuhartnoreply@blogger.com
