Studying the problem to find the right ßeta

 

Note (from the Betamax Wikipedia entry):

 

»In rock climbing, to give guidance as to how to climb a particular route is called "giving beta". This is due to climbers sometimes videotaping other climbers on climbing routes using the Betamax format (when it was still in use), then reviewing the tapes to evaluate techniques to help them climb the same routes in the future.«
