How Hedy Lamarr Invented Early Wireless Technology
Unhappy being pigeonholed due to her looks, the “most beautiful woman in the world" set out to develop a secret communication system that would take down Nazi submarines.
A lonely immigrant from Austria slips out of her stage clothes and kicks off her heels. Carefully removing her movie makeup, she's dissatisfied that she's been overlooked for more significant roles. Instead of throwing a pity party, however, she heads determinedly for her drafting table, a place where she has previously invented an improved traffic stoplight.
This is where she'll prove to the world that she's more than a pretty face.
This is the real-life story of Hedy Lamarr, Hollywood actress turned tech hero. An inventor whose contributions helped develop a system used in Bluetooth, GPS and Wi-Fi.
She had a knack for designing problem-solving technologies. Transforming the drawing room in her house into an innovation studio with a drafting table and the necessary tools Lamarr invented an aid to help people with limited mobility get in and out of the bath. She also invented a fluorescent dog collar and a bouillon cube* that would dissolve to turn water into soda.
Her best-known success was a passion project that still has applications today. The “secret communication system" she developed with composer George Antheil, a neighbor and friend, was the precursor to today's top wireless technologies. Together, they developed a radio communication system based on the 88 piano keys. It was a success, and the duo received a patent for their work in 1942. Unfortunately, the U.S. Navy ignored their technological feat for another 20 years.
Late, the system became the precursor to modern wireless technologies. Their work remained unrecognized until 1997, when the Electronic Frontier Foundation acknowledged Lamarr and Antheil. When Lamarr heard the EFF was giving her an award, her first words were, 'Well, it's about time.'

infer what is primary problem of heating on earth atmosphere and how would you solve this problem?
The primary problem is the greenhouse effect. Greenhouse effect is when some gases (including CO2) absorbs some portion of sun's heat to make the atmosphere warm to support life. But when the amount of CO2 etc. increases in the atmosphere, it heats up more than it is required. So, by limiting CO2 emission, we can solve this problem.

Read the following excerpt from a personal narrative essay. Based on the excerpt, what did the writer learn from her personal experience?
Have you ever been canoeing? I went on a canoeing trip with my mom, dad, and two brothers when I turned 13. It was one of the best days of my life. It was exciting, scary, and challenging all at once. At first I couldn’t believe those long, narrow pieces of wood could hold all five of us. But our instructor told us that canoes have been around for many years. He also told us some interesting facts about the history of canoe, like how American Indians used canoes as a way to travel quickly.
He patted the wood of the canoe we would be using. “It’s made of an old tree trunk,” he said.
I asked the question that had been bothering me ever since I saw our canoe. “Can it really hold all of us?” I pointed to my brothers and me. “It looks like the bottom could fall right off.”
The instructor laughed. “Oh, you’ll be surprised how strong this wood is. If our customers were always drowning, we’d have a 'sinking' business on our hands.”
He laughed some more at his own joke. Then he became serious and showed us how to keep our balance while getting into and out of the boat. He also showed me how to grip the paddle so that my left hand would guide the boat and my right hand would give the paddle power.
A.
Canoeing is dangerous, and only people who are experts can do it.
B.
Even events that seem a little scary can turn out to be great.
C.
The best age to go on a canoeing trip is 13.
D.
Canoeing can cause injury if you’re new to the sport.
Answer:
B. Even events that seem a little scary can turn out to be great.
