Hie yourself to some ocean... go to a west coast, that borders on that sea... some coast having FEW waves...

hey, Barbados would be great!

Lie down; lay yourself down... at waters edge ... just at set of sun ...

Nose to sea, watch, and think ... as the sun vanishes.

And, then, stand yourself up! The Sun will Rise!

... well, but slightly; however ... bright as it is, you won't miss it!

Now ... time the SECOND SETTING of the sun!

Elephant-one ...
Elephant-two ...
Elephant-three ...

Ten seconds later, I predict, the Sun will set again.

OK!

Your task ... should you choose to accept it ... is to ...

... calculate the radius of our dear planet Earth.

(HERE's how you do it !)
