I am a scientist, inventor, volunteer, patentholder and grandfather of three.
For me it is more about making my world a better place by helping to make your world a better place.
Keep an eye on my blog and you may find something posted one day that will help you improve your world. And that automatically improves my world.
Key thing is "Do I understand what I have learned well enough, to apply it to practical solutions.
problem solving, reading, quantum physics, science, patents, writting, fun with grandchildren. all that life has to offer and everyday wishing and praying for more time to explore it all.
