Where I can I find the animated version of the virtual particles picture on page 70 of A Universe from Nothing? Thanks in advance, John.

Amazing that this man can write "Why Evolution Is True" and also respond intelligently to free will issues. I met him briefly in 2009, oh frabjous day.

To my Econ-coned friends, some amusing (if not all feasible) approaches to email management.

I saw the static version in Lawrence Krauss' "A Universe from Nothing." At his lecture last week, he used this animated GIF. If I understand it, this is a representation of virtual particles coming into and going out of existence in our Universe. They play a role in Krauss' overall argument regarding the possibility/probability of our Universe having been "created" from Nothing. The catch is that Nothing is not really "nothing" as we normally think of it. But I've only read his one book and haven't studied physics since Dr. Rolleigh's class back at Hendrix...we did not cover dark matter and virtual particles!

We were there for this lecture. Who knew cosmology could be so interesting?

I was in town for just a few weeks and needed to find a dentist who could see me quickly. Drs. Finnerty, Wu and Palabrica fit the bill perfectly. Dr. Palabrica saw me on the same day I called the office, then she and her staff provided excellent dental care that day and on a few follow-up visits. All my interactions with Dr. Palabrica and with her office were very pleasant. I will definitely return their office the next time I am in DC and need dental work. Highly recommended. -John
