On the Guest Blog – two posts today.
First, in a response to an SA article that was perhaps a little bit too optimistic, Joseph A. Dick offered a detailed analysis – Helium Hokum: Why Airships Will Never Be Part of Our Transportation Infrastructure
Charles Q. Choi nabbed a big name today – Too Hard for Science? E. O. Wilson–A Vertical Map of Life on Earth.
Over on the Expeditions blog, Wendy Whitcombe – one of the students in the Problems Without Passports course – penned her first post: Some History Should Not Repeat Itself
And on the Anecdotes from the Archive, Mary Karmelek discovered another gem in the SciAm archives: How to Find the True Shape of a Soldier.
