One of the deadliest earthquakes in history struck Lisbon, Portugal, in 1755, killing at least 30,000. The earthquake, followed by a tsunami and raging fires, almost totally destroyed the city, leaving just 15% of its buildings standing. The study of the quake’s causes led to the beginnings of seismology. Geologists today estimate that the temblor, with an epicenter in the Atlantic Ocean, approached magnitude 9 on the moment magnitude scale. How did the quake influence philosophers of the time?

Five years after being granted a patent for the first practical sewing machine, Howe patented his design for a zipper-like garment fastener. However, he never put much effort into marketing this invention, perhaps due to the great success of his sewing machine, and today, credit for the zipper’s development is largely given to Whitcomb Judson, who demonstrated his innovative slide-fastener design 42 years later at the World’s Columbian Exposition of 1893. How did the zipper get its name?
