Heres a famous image, the word 'IBM' made up of individual gold atoms.

Since then they have improved the technique, heres the symbol 'Si' written in Silicon atoms on a tin substrate.

Would it make a difference if the ball was a tennis ball, or a cricket ball? ie the surface area of the ball? Would it make a difference if the ball was thrown at the poles or the equator?, or in a vacuum?

I think Mr Newton says Non!

Everyone picks on the Poles. They are part of Europe - get over it.

I dare say Mr Dyson wouldn't be best pleased either.

A ball thrown vertically from the equator will appear to follow a curved path when seen from the (moving) ground. In the interests of accuracy you should do the experiment at a pole.

or in a vacuum?

You don't need a vacuum but you do need zero wind speed.

actually that was bordering on witty, for joe.

Indeed, the Germans would be lost without the Poles - ( previously know as the Prussians). They would be buggered for anywhere to invade, for a start.
