Highlights

Nitroglycerin is a molecule that revolutionized the world as an explosive, being a thousand times more potent than black powder.

Black powder, invented by Chinese alchemists, was the dominant explosive for a thousand years due to its stability and ease of preparation.

Despite its widespread use, black powder had limitations, such as producing a lot of smoke and requiring large amounts for effective explosions.

Ascanio Sobrero, an Italian chemist, discovered nitroglycerin in 1847 by combining glycerin with a mixture of nitric and sulfuric acids.

Nitroglycerin's discovery was accidental and resulted in a violent explosion that scarred Sobrero for life.

The accidental ingestion of nitroglycerin by Sobrero led to the discovery of its medicinal properties, despite its explosive nature.

Nitroglycerin produces 275,000 atmospheres of pressure upon detonation, compared to the 6000 atmospheres of black powder.

Nitrocellulose, discovered by Christian Friedrich Schonbein, was the first plastic explosive and inspired Sobrero's discovery of nitroglycerin.

The fire triangle of nitro explosives is contained within the molecule itself, unlike black powder where each ingredient contributes to one element of the triangle.

Nitrocellulose burns almost instantly due to the fire triangle being present within each molecule, making it a powerful but safe explosive.

Alfred Nobel, after the tragic death of his brother Emil, was determined to stabilize nitroglycerin for safer use in industries.

Kieselguhr, or diatomite, was the key ingredient that Nobel used to stabilize nitroglycerin, creating a plastic paste that was safer to handle.

Dynamite, Nobel's invention, combined the power of nitroglycerin with the safety of a stable explosive, leading to immense industrial and financial success.

The Nobel Prizes, established by Alfred Nobel's will, have recognized contributions to humanity in various fields for over a century.

Modern nitro explosives like TNT and RDX prioritize stability and require a triggering blast for detonation, making them safer to manufacture and handle.

Nitroglycerin's impact on society was profound, enabling the construction of mega-structures and revolutionizing the transport of people and goods.
