This is the full version of my answer to a question formulated by Francisco A. Doria to me included in the Discussion Section of A Computable Universe, my edited volume being published by World Scientific and Imperial College Press coming out next month (already available in Asia) concerning whether I think if Hypercomputation is possible: […]

## Meaningful Math Proofs and “Math is not Calculation”

Mathematicians are generally thought to be very good at calculation, and they sometimes are, but this is not because math is about calculation, just as astronomy is not about telescopes and computer science is not about computers (paraphrasing Edsger Dijkstra). But if it is not preeminently about calculation, then what is mathematics about? The common […]

He claims: “We only have to look at ourselves to see how intelligent life might develop into something we wouldn’t want to meet.” Stephen Hawking recent assertion looks like an […]

## The art of creating creatures from simple rules

Having quit his studies in physics, Theo Jansen became an artist. In this video he demonstrates his amazing life-like kinetic sculptures, built from plastic tubes and bottles. His Beach Creatures or Strandbeest are built to move and even survive on their own: I’ve been in touch with Theo Jansen recently. For further details about his […]

## NKS Cooking

A novel approach to cooking The algorithm: Consider the space of all possible recipes. Enumerate the ingredients per food style (Mexican, Chinese, French, Italian, and so on). Take the subsets of the ingredients per food-style set. Begin with a random choice of initial ingredients. Mix them by following a set of simple cooking rules like baking, […]
