The light bulb
Our reliance on natural light was removed by the development of the light bulb, which allowed us to be productive day or night. Several inventors contributed to the creation of this ground-breaking technology throughout the 1800s, but Thomas Edison is recognized as the primary inventor because in 1879 he developed a fully operational lighting system that included a generator, wiring, and a carbon-filament bulb similar to the one above.
This innovation led to the widespread use of electricity in Western homes and also had the fairly unanticipated effect of altering sleep habits. We no longer stay up past the 7 to 8 hours allocated for sleep and, in a perfect world, we sleep all at once. In the past, when we had nothing better to do, we went to bed at nightfall and slept intermittently throughout the night.
Penicillin
One of the most well-known historical discovery tales is this one. In his lab in 1928, the Scottish researcher Alexander Fleming discovered a Petri dish full of germs with its lid inadvertently ajar. The sample had developed a mold contamination, and wherever the mold was present, bacteria had died. In the following two decades, scientists refined the antibiotic mold, which turned out to be the fungus Penicillium, and created the medicine penicillin. Penicillin treats a wide range of bacterial illnesses in people without endangering the patients.
By 1944, penicillin was being manufactured in large quantities and promoted. In order to prevent venereal disease, this message on a curbside mailbox instructed World War II personnel to take the medication.
According to a 2003 study in the journal Clinical Reviews in Allergy and Immunology, about 1 in 10 persons experience an allergic reaction to the antibiotic; nevertheless, most of these patients go on to be able to take the medication, researchers stated.
