Ten Coolest Things Invented By Women
The Circular Saw was invented by Tabitha Babbitt, a weaver, who lived in a Shaker community in Massachusetts in the late 18th century. Today, circlar saw is widely used and regarded as a very important tool for woodcutters. Babbitt noticed that men in her community were using a pit saw, which is a two-handled saw that requires two men to pull it back and forth. Though the saw is pulled both ways, it only cuts wood when it's pulled forward; the return stroke is useless.
She attached a circular blade to the spinning wheel she used in her weaving, and the result was a device where every movement of the saw produced results. Because of her religious principles as a Shaker, Babbitt didn't apply for a patent for the circular saw she created. And this is how we got Circular Saw.
#9 Windshield Wiper
Ever wondered who invented the windshield wiper of your car? It was Mary Anderson. In the early 20th century, Mary Anderson came up to New York City from Alabama on vacation. During her trip, Anderson took a tram through the snow-covered city, and noticed that every few minutes the tram conductor had to step out and clean the windshield in order to see. Since cars were so new at the time, no one considered it to be unreasonable, as it was "just something drivers had to deal with."
She decided to solve the problem she faced during her vacations. When she returned home to Alabama she developed a squeegee on a spindle that was attached to a handle on the inside of the vehicle. When the driver needed to clear the glass, he simply pulled on the handle and the squeegee wiped the precipitation from the windshield. Anderson received the patent for her device in 1903; just 10 years later, thousands of Americans owned a car with her invention.
Almost all of us have played this. Elizabeth Magie created The Landlord's Game to spread the economic theory of Georgism-teaching players about the unfairness of land-grabbing, the disadvantages of renting, and the need for a single land value tax on owners. Magie patented the board game in 1904 and self-published it in 1906.
#7 Foot Pedal Trash Can
Dustbins are so useful specially the ones with foot pedal in them. Lillian Gilbreth improved existing domestic inventions with small tweaks. Amongst her other inventions were shelves inside refrigerator doors, and improvements on the can opener. One day she invented a foot pedal for the trash can, as she was constantly tweaking here and there, it was just another in a long line of achievements created by Gilbreth.
#6 The Solar House
So it was a women who first decided to utilize the solar energy. In 1947, the Hungarian scientist invented the thermoelectric power generator to provide heat for Dover House, a wedge-shaped structure she conceived with architect Eleanor Raymond. Telkes used Glauber's salt, the sodium salt of sulfuric acid, to store heat in preparation of sunless days. Dover House survived nearly three Massachusetts winters before the system failed.
#5 Non-Reflective Glass
This is one of the coolest inventions ever. In 1938, Katherine Blodgett patented the film and process that resulted in the world's first 100% transparent or invisible glass. The process requires applying minute layers of monomolecular coatings of film to the glass. The result was glass that eliminated glare and distortion.
This is a very important invention in the world of medicine. In 1948, Elizabeth Lee Hazen and Rachel Fuller Brown teamed up to develop nystatin, the first non-toxic drug treatment for fungal infections in humans. Hazen and Brown were doing research for the Division of Laboratories and Research of the New York State Department of Health, when Hazen found a promising micro-organism in the soil of a friend's dairy farm. She named it Streptomyces noursei, after William Nourse, the farm's owner.
#3 Telephone switch system
Yes, even this was invented by a women. Telephone switch system: to help eliminate the issue of call overloads, Erna Schneider Hoover invented the computerized switch system which automatically adjusted the phone's acceptance rate of calls.
#2 Radioactive metals
Everyone knows about this. Marie Curie's discovery of radium and polonium led her to discover that the properties of the two metals were able to kill tumors. Marie Curie is the only woman to be awarded the Nobel Prize twice, with the 1903 Nobel Prize in Physics and the 1911 Nobel Prize in Chemistry.
During her storied research career, Curie invented a theory of radioactivity (a term that she herself coined), techniques for isolating radioactive isotopes. She founded the Curie Institutes in Paris and in Warsaw, which remain major centers for medical research today. And now we get to study this, WOW!
#1 Chocolate Chip Cookies
This is the yummiest of all the inventions that we saw today. Sometimes the greatest inventions are the simplest ones. No one really thinks about where chocolate chip cookies first came from, we just don't even think about a world when they didn't always exist. But in 1930, Ruth Wakefield came up with the chocolate chip cookie, creating not just a wonderful treat beloved by children and adults the world over, but also an iconic symbol of comfort in simplicity.
Wakefield substituted broken pieces of Nestle's semi-sweet chocolate, expecting it to melt and absorb into the dough to create chocolate cookies, but instead she accidentally invented chocolate chip cookies. She contacted Nestle and they struck a deal where the company would print her recipe on the cover of all their semi-sweet chocolate bars, and she would get a lifetime supply of chocolate. And now we enjoy it.
