Be happy and take relief by wasting one's future. Good bless you all the happyness of this world to you Be happy
God bless you
Answer Let's keep these posts to science, yes? The eye is a simple lens. But learn to do some basic research BEFORE you ask questions about the parts you don't understand. Here's everything you need to know about vision (physics, the biology part you need biologists for): http://hyperphysics.phy-astr.gsu.edu/hbase/vision/visioncon.html#c1
I can answer most basic physics questions, physics questions about science fiction and everyday observations of physics, etc. I'm also usually good for science fair advice (I'm the regional science fair director). I do not answer homework problems. I will occasionally point out where a homework solution went wrong, though. I'm usually good at explaining odd observations that seem counterintuitive, energy science, nuclear physics, nuclear astrophysics, and alternative theories of physics are my specialties.
I was a physics professor at the University of Texas of the Permian Basin, research in nuclear technology and nuclear astrophysics. My travelling science show saw over 20,000 students of all ages. I taught physics, nuclear chemistry, radiation safety, vacuum technology, and answer tons of questions as I tour schools encouraging students to consider careers in science. I moved on to a non-academic job with more research just recently.
Education/Credentials Ph. D. from Duke University in physics, research in nuclear astrophysics reactions, gamma-ray astronomy technology, and advanced nuclear reactors.
