valuing gold - the value of gold

valuing gold - the value of gold: which is worth more, a kilogram of stone or a kilogram of gold? the question about its value probably seems ridiculous but only to the merchant.  the artist will always answer "all materials are equally valuable as I am concerned". 
Venus de Milo would be equally precious, whether made of common stone or gold... 
in Paros Greece the streets are paved with marble - in Wall Street with stone

S.T.E.M. Education - science, technology, engineering and mathematics

Here's a unique Italian twist on S.T.E.M. Education anno 1962 presented by Lambretta.  STEM is a curriculum based on the idea of educating students in four specific disciplines — science, technology, engineering and mathematics — in an interdisciplinary and applied approach.  Hailed as something futuristic; STEM has been around for centuries.  Case in point, the master of STEM; Mr. Leonardo da Vinci.  This vintage Lambretta video proves it's always a good time to lighten up and keep things in perspective.  So don't stress out.  Enjoy the ride.
