One hundred years after her death, in 1953, Ada's notes on Charles Babbage's "Introduction to Analytical Machines" were republished, which was recognized as having a great influence on modern computer and software engineering.

4. nikola tesla-"the life of the future traveler"
Tesla coil, amplifier transmitter, Tesla turbine, video, radio, neon lights, alternating current, etc. He owns more than 3 patented scientific and technological inventions. He is a great inventor and physicist. His inventions have a great influence on later generations. Many of his research projects are far ahead of the times, and the technical conditions are far behind, so it is difficult to complete them in his lifetime.
Because Tesla's ideas are far ahead of his time, most of his advanced ideas can only be feasible in theory, so Tesla has never been recognized by his main competitor Edison.
5. meredith goulding
meredith goulding worked in the field of electrogas dynamics, and helped to invent electrostatic precipitator, including "garbage incinerator", which can help to remove smoke from burning buildings and fog on runways. He also invented a system that can use the same principle to help cool circuit breakers and computer chips.
