Today’s Google Doodle pays tribute to Alexander Calder who invented Mobile (not the mobile phone) almost 80 years back. All parents should thank this man as this simple invention has kept most infants engaged and it still fascinates them.

I love some of his quotes:

Out of different masses, tight, heavy, middling—indicated by variations of size or color—directional line—vectors which represent speeds, velocities, accelerations, forces, etc. . . .—these directions making between them meaningful angles, and senses, together defining one big conclusion or many.

Nothing at all of this is fixed.

Each element able to move, to stir, to oscillate, to come and go in its relationships with the other elements in its universe.

It must not be just a fleeting moment but a physical bond between the varying events in life.
