@neiltyson why are air blasts more powerful in non-nuclear explosions (ie spreading the radiation farther not an issue)? -
@staringispolite@neiltyson Check the damage done by a Fuel-Air Explosive (FAE) as an example. http://en.wikipedia.org/wiki/Thermobaric_weapon … http://news.bbc.co.uk/2/hi/europe/6990815.stm … -
@jsturges@neiltyson I know air blasts *are*, but I'd like to understand the mechanics of it. More of downward force from point of origin...
