1833-1896
In this "explosive" podcast, Mark and Jack discuss nitroglycerin and the man responsible for inventing dynamite, Alfred Nobel. Listeners will get a bang out of learning what differentiates high explosives from low explosives and how these molecules "do what they do" from a chemical and physical perspective. So sit back and have a blast listening about why Nobel founded the prestigious international prizes that bear his name.
