@visitor - it was a discovery at the first stage and invention at the second stage (medical application and production). Nobody uses Penicillin in the form it was discovered (food contaminated by blue-green mould). An example of discovery is that Earth is round but there's no 2nd stage - nobody tries to make Earth triangle so that we can use it in a more convenient way. - Metal_TreasureV 2 Comments
It was accidentally discovered in 1945 by Percy Spencer, an American self-taught engineer. He was working on an active radar set and noticed that microwaves from the radar started to melt a candy bar in his pocket. And he decided to use the specific heating effect of the high-power microwave beam.
The first food deliberately cooked with Spencer's microwave was popcorn, and the second was an egg, which exploded in the face of one of the experimenters. - Metal_Treasure
Viagra (Sildenafil) was meant to treat heart diseases: hypertension (high blood pressure) and angina pectoris (a symptom of ischaemic heart disease).
The first clinical trials suggested the drug had little effect on angina but induced marked penile erections. - Metal_Treasure
The artificial sweetener was discovered in 1879 because chemist Constantin Fahlberg didn't wash his hands. - Metal_Treasure
