• This highly accurate timekeeping device was crucial for determining longitude at sea, revolutionizing navigation and significantly improving the safety of long-distance sea travel.

• He published his work on logarithms in 1614, in a book titled "Mirifici Logarithmorum Canonis Descriptio" (Description of the Marvelous Rule of Logarithms).
• His invention provided a revolutionary tool for simplifying complex calculations, particularly in astronomy and navigation, by transforming multiplication and division into addition and subtraction.

• He invented Rocket. He achieved this significant milestone on March 16, 1926.
• His work was foundational for the development of modern rocketry and space exploration.

• In 1880, he successfully operated an electric tramcar near St. Petersburg, using an electric current transmitted through the rails.
• While not immediately commercially successful on a large scale, his work was a significant early step in the development of electric tramways.

Key Facts:

• Franklin conducted famous experiments with electricity, including the kite experiment in 1752, to prove that lightning is a form of electricity.

• Based on his findings, he designed the lightning rod to protect buildings from lightning strikes by directing the electric charge safely into the ground.

What is a Lightning Conductor?

A lightning conductor is a metal rod mounted on top of a building and connected to the ground. Its purpose is to:

• Attract lightning strikes, and

• Safely conduct the electric charge into the earth, preventing damage to structures.

Key Facts:

• Ted Nelson, an American computer scientist, coined the term "hypertext" in 1965.

• He introduced it as part of his Project Xanadu, which aimed to create a universal, non-linear writing and reading system.

• Hypertext refers to text displayed on a computer or device that contains links to other text, allowing for easy navigation — a foundational concept of the World Wide Web.
