Additional Information on Dynamite and Alfred Nobel
Dynamite is an explosive material consisting of nitroglycerin, sorbents (like diatomaceous earth), and stabilizers. Alfred Nobel patented dynamite in 1867. Before dynamite, liquid nitroglycerin was used, but it was highly unstable and dangerous. Nobel's invention made the handling and use of explosives much safer and more practical for construction, mining, and quarrying. The wealth he accumulated from his inventions, including dynamite, allowed him to establish the Nobel Prizes, awarded annually for achievements in physics, chemistry, medicine, literature, peace, and economic sciences.
