About Me

Science communication is important in today's technologically advanced society. A good part of the adult community is not science saavy and lacks the background to make sense of rapidly changing technology. My blog attempts to help by publishing articles of general interest in an easy to read and understand format without using mathematics. I also give free lectures in community events - you can arrange these by writing to me.

It is obvious that our manufacturing top-down methods are wasteful and inefficient.  We have a lot to learn from nature's way doing nanotechnology.  As it happens, without realizing it, chemists have been using nanotechnology to produce new chemicals etc.
