Interview with Ganesh Kumar

It was a privilege to interview Mr. Ganesh Kumar M.R., Software Architect at Applied Materials, who has over 10 years of experience in development of Image Processing Algorithms for medical and semiconductor products. His experience as a Junior Research Fellow (JRF) in IISc, Bangalore and over 9 years of experience in GE Healthcare, a company involved in medical imaging, made us inquisitive so as to know how the Medical Imaging Industry works! Thank you, sir, for having agreed to do this interview! To begin with, you had done most of your education in Physics. What is it that made you so passionate about the field? Physics is about trying to come up with explanations of nature-its origin and what it is- by equations and concepts. For example, when it rains, even the pattern of fall of the rain drops follows Poisson’s noise distribution. Similarly, rainbow formation too has physics involved behind it. This has intrigued me a lot and made me develop interest in it. So, what made you swit...

Evolution and Intelligent Design

 The eye, as we all know, is the sensory organ responsible for perception of light. In the higher organisms especially, the eye is an optical system so complex that even Charles Darwin quoted that “The evolution of eye by natural selection at a first glance seems  absurd in the highest possible degree .” However, he went on to quote if the evolution of eye had occurred in steps- from a simple, imperfect design, which nonetheless conferred some advantage to the organism- its evolution seems perfectly feasible. This is exactly what happened millions of years ago! In the beginning, life was blind. Then one day, about a 500 million years ago, there occurred a mutation in the DNA of a microscopic bacterium, which led to the translation of a photosensitive protein. This protein helped the bacterium to distinguish light and darkness, which was sufficient for synchronisation of the circadian rhythm. This bacterium then propagated its DNA through the process of replication and over tim...
