Which came first penicillin telescopes pyramids or typewriters?

Answer 1

Pyramids may date back as far as 5,000 B.C. Research is going on in Sudan. Some day you may join a dig looking for the earliest ones.

Telescopes go back to the 1500s. Galileo discovered the moons of Jupiter using a telescope.

Attempts to make a typewriter go back to the 1800s, if not earlier. Around 1870 Thomas Edison took one model and upgraded it so it could take quite a pounding.

People had been using green moldy bread as a treatment for years. Then Dr. Flemming took the substance from the mold and discovered the most appropriate dose for each person. That started in the 1930s. Until that point, military hospitals were more dangerous than battlefields. Penicillin prevented a number of deaths in military hospitals in World War 2. It became available to the general population in 1945

Answer 2

The pyramids came first, as they were built around 2580–2560 BC. The telescope was invented in the early 17th century, with the first recorded patent in 1608. Penicillin was discovered in 1928 by Alexander Fleming. Typewriters were invented in the 1860s, with the first commercially successful model, the Sholes and Glidden typewriter, introduced in 1874.

Answer 3

The pyramids came first, followed by telescopes, then typewriters, and finally penicillin. The pyramids were built around 2600 BC, telescopes were invented in the early 17th century, typewriters were introduced in the 1870s, and penicillin was discovered in 1928.
