Five Popular Talks

Over the last ten or fifteen years I’ve done a number of slide talks at Balticon, Philcon, & Farpoint, three local science fiction conventions. A number of these have been relatively heavy on the physics – within the context of a science fiction convention of course – and I thought it might be fun to post them. As Rod Sterling might have put it, presented for your consideration:

Relativistic Morlet Wavelets

Wavelets are like musical notes: they are wave forms limited in both time and frequency. What makes them particularly useful is that any reasonable wave function may be written as a sum over them.

Usually we think of music in terms of pure tones, in terms of its Fourier components. But pure tones can be a bit too pure. For one thing, if a tone is to be completely pure it has to last forever, not a characteristic associated with practical questions. Wavelets are impure tones, and therefore a better match to the real world.

“Quantum time” slightly less fuzzy: clean copy up.

I’d like to thank Ferne Welch and Arthur Tansky for copy-editing the previous version of “Quantum Time“.  It bears a significantly greater resemblance to English now!

And I would like to thank Jonathan Smith and also Mark West and Ashleigh Thomas for help in getting setup at University of Pennsylvania.

If anyone knows a bibtex style that handles electronic references well, please let me know.   If no suggestions, then I think I will warm up learning Old Kingdom hieroglyphs, then tackle bibtex.

All comments on Quantum Time are very welcome.  I’m planning to fold such into the great work of time as appropriate, then, if not too discouraged, push Quantum Time to the archive.
