After a hiatus for the month of July, the National Science Foundation’s popular Cafe Scientifique (Arlington) is back. August’s cafe speaker will be geologist Dr. Tom Wagner, under the topic heading “From Dust to Us: a Brief History of the Earth and Moon”. Dr. Wagner is a lead scientist for NSF’s Antarctic Geology program and an expert in volcanoes, climate, and Antarctica, among other things. And how often do we get to talk about things like volcanoes and Antarctica here in Our Nation’s Capital? That’s right, not often enough.

With a Ph.D. from MIT and a research background in volcanology and petrology, Dr. Wagner is in between trips to Antartica, but was able to fit Cafe Scientifique into his busy travel schedule.

Considering the history of the earth and moon are rather expansive, it will be nice to hear Wagner’s condensed version of such. Cafe Scientifique is all about questions from folks in the audience, so come armed with anything you’d like to know about the earth or moon that you’ve been dying to ask an expert about.

Geologist Tom Wagner will present From Dust to Us: a Brief History of the Earth and Moon on Tuesday, August 1 at The Front Page in Arlington. 6 to 8 p.m., free.
