Alfred B. Nobel invented dynamite in 1867 and established the Nobel Prizes. Franklin, Edison, and Diesel made other important inventions but not dynamite.

Michael Faraday discovered electromagnetic induction in 1831, leading to the electric generator. Bell invented the telephone, Edison the light bulb, and the Wright brothers the airplane.

Thomas Alva Edison developed the practical electric lamp in 1879, making electric lighting commercially viable. Nobel invented dynamite, Franklin studied electricity, and Otis invented elevator safety brakes.

Benjamin Franklin invented the lightning conductor (lightning rod) in 1752 to protect buildings from lightning strikes. Otis invented elevators, Diesel the diesel engine, and Faraday worked on electromagnetism.

Elisha G. Otis invented the safety elevator in 1852, making skyscrapers possible. Diesel invented the diesel engine, Faraday the generator, and Edison the light bulb.

Benjamin Franklin invented bifocal lenses around 1784 to address both near and far vision problems in the same pair of glasses. He was both a statesman and prolific inventor. Faraday, Bell, and Edison made other important contributions but did not invent bifocals.

The microphone, specifically the liquid transmitter type, was invented by Alexander Graham Bell in 1876 as part of his telephone system development. While Emile Berliner also developed a microphone later, Bell is credited with the foundational invention. Diesel, Fahrenheit, and Edison made contributions in other fields.

Daniel Gabriel Fahrenheit invented the mercury thermometer in 1714, creating a temperature scale that bears his name. His design used mercury in a glass tube, offering more precise and consistent readings than alcohol-based thermometers. Bell and Franklin were accomplished in other fields, while the Wright brothers pioneered aviation.

Bab-el-Mandeb is known as the 'Gateway of Tears' or 'Gate of Tears' - a strait between Yemen on the Arabian Peninsula and Djibouti in Africa. It connects the Red Sea to the Gulf of Aden and Indian Ocean. Korea, Australia, and Canada are not related to this strait.
