Condensing Steam EngineThe Watt condensing steam engine is widely viewed as the primary machine responsible for the Industrial Revolution. It enabled the use of engines anywhere, not only next to coal mines. Whereas factories before the Watt engines needed to be near high-volume streams, to derive power for water wheels, the Watt engine operated at a low … Continue reading "Condensing Steam Engine"
LaparoscopyFor centuries surgeons have been purposefully cutting holes in people trying to heal them. Background Before anesthesia, antibiotics, and Lister’s germ theories surgery often meant a slow and painful death from infection. Putting things into perspective, more people died in the US Civil War from infection than from direct strike of a weapon. Purposefully cutting … Continue reading "Laparoscopy"

Deere thought there must be a … Continue reading "Moldboard Plow"
PasteurizationFrench scientist Louis Pasteur disproved the theory of spontaneous generation, the idea that certain organisms are ever-present in nature.

Different color threads might be used on different … Continue reading "Programmable Machine (Jacquard Loom)"
AsphaltAsphalt increased the utility or roads by allowing horses to travel faster, carriages and bicycles ride more smoothly, and (later) enabled cars. Natural asphalt paved the Champs-Élysées in 1824. However, it was unstable and difficult to maintain. de Smedt created an artificial asphalt, manufactured from oil, that was more consistent and manageable than natural asphalt. … Continue reading "Asphalt"
