Heavy lifter fitness machine

Make a fitness machine that lets you use all your muscles at once (including arms, legs, abs, chest, neck hands, all of em!) to see how much you cam lift.  Cables and gears would connect it all together so the energy you exert from every individual part combines into one force used to lift a weight.

The power and decline of the polymaths

Great article, a little depressing since I identify with the curiosity and breadth of knowledge that these types of intellects develop. I feel that lots of creative thinkers are not, do not want to be, or simply cannot be specialists, and that there is a real value in this versatility and variety. To a large extent it is the breadth, not the depth of knowledge that inspires me.
