Dynamite
Dynamite was invented by Alfred Nobel, a Swedish chemist, in the 1860s.
Prior to its invention, gunpowder (called black powder) had been used to shatter rocks and fortifications. Dynamite, however, proved stronger and safer, quickly gaining widespread use.
Alfred called his new invention dynamite, after the ancient Greek word ‘dunamis’, meaning ‘power.’ He did not want it to be used for military purposes but, as we all know, the explosive was soon embraced by armies across the world
The photograph
In 1826, French inventor Joseph Nicéphore Niépce created the first permanent photograph from a camera image.
Niépce captured the photograph from his upstairs window using a camera obscura, a primitive camera, and a pewter plate, having experimented with various light-sensitive materials.
This, the earliest surviving photograph of a real-world scene, depicts a view of Niépce’s estate in Burgundy, France.
