Musings are not meant to provide answers. They are meant for stretching thinking muscles.

A simple formulation of law of conservation of energy can be as under:

Energy cannot be created or destroyed, but only changed from one form into another or transferred from one object to another.

A slightly more complex version of this law adds a qualifier:

What I call a 543 model is correctly called a rhombicosidodecahedron. It is often abbreviated as RID.

As prior to thinking about this I had taught the students of Vigyan Ashram how to build a big lantern based on only squares and equilateral triangles, it was logical to call this shape based on pentagons, squares and equilateral triangles as 543 reflecting the number of sides of the shapes inside it. The previous shape is then called 43. Here are two pictures.

These are the first clips from Lorin Symington's quest to establish the first solar fire powered bakery in Haiti.

With fuel costs on the rise in Haiti, baked goods are becoming more and more expensive. The team at is pioneering a new sustainable energy based business model that they hope will spread first in Haiti, then around the world.

Introduction to Prosthetics and their manufacture

Prosthetics are parts that fit into a human body to complete a function that has been lost/impaired. Ears cannot hear clearly; eyes have difficulty in seeing clearly; limbs have been cut off or were never present. Cochlear implants in the ear canal improve hearing; lenses are inserted into the retina to improve eyesight; artificial limbs aid walking and functioning of hands.

Last June, I took part in the InnoCentive Challenge # 9933575 - Polypropylene Packaging Film Replacement. I submitted a written proposal for novel packaging materials to replace polypropylene films, providing a better biodegradability and the same or greater moisture barrier. Since the Seeker Scientists have chosen not to employ the solution that I submitted, I am now placing it in the public domain for all to see and use freely if it suits them.
