I'm posting physics related stuff and hope it is useful. Post things that make you think, and give ideas for you to build on. Enjoy.

Physics Teacher with a long involvement in lasers and holography. Built and run laser shows with a number of rock bands but I still like the small stuff that anyone can do with a simple key chain or laser pointer. If you made a hologram in school in the past 20 years you probably used the techniques I created.

"Dr. Altman". For four years I was functioning with a Ph.D. issued by an online university based on my (life experience) work in lasers and holography. They are no longer in buisness so my doctorate is only as good as the paper it was printed on. At any rate, I'm going to change my first name to "DR" because that would be a lot easier than editing all these videos! Live and learn.
