ON THE IMPORTANCE OF EDUCATION
(ONCE AGAIN)

Generally, evident truths do not require mathematical confirmation, but it is pleasant to run into a strict proof time to time. Here is a recent example (reportedly, due to Rob Howard of Next Level Systems).

It is well known that "Knowledge is Power", and "Time is Money". In the algebraic form,

K = P,   T = M.     (1)
On the other hand, power is work per unit time, i.e.
P = W/T.              (2)
Plugging Eqs. (1) into Eq. (2), and solving for M, we get
M = W/K.
Thus the more knowledge the less money (at fixed total work), in good correspondence with recent experimental observations. Keep telling your students to study hard, friends.
