inventions:
Zipper (be glad it's there to hold your pants)
Java computer language
light bulb (in Canada 1 year before Edison "invented it)
Frozen meals (two years before it went for sale in the U.S.)
Wonder Bra (ask your wife if she appreciates it)
Snow blower (not that you care)
Snowmobile
Finger prints readers
Insuline
Blackberry (the phone, not the fruit)
Sonar (yes, another great Canadian invention)
Telephone (woman's best friend )
AIDS medication 3TC
G-Suits (ask your Air Force if they appreciate)
Electron microscope
Electric wheelchair
Canada arm (really appreciated on the space shuttle)
Artificial hand (myo-electric)
Baseball (yes, it was played in Canada before migrating to the U.S.)
And I could bring many more.
There's a joke that goes like that:
In January, the Americans announce an invention
In February, the Russians announce they invented it 20 years before
In March, the Japaneses put it on the market.
It is true you have quite a few geniuses in the States, but some other countries also do.
Now, I hope this pi$$es you off too. Actually it really doesn't *piss me off*. You should be proud of the accomplishments of your fellow countrymen. Except for that baseball thing all the rest were pretty good inventions.
But as for the zipper: Quote: The design used today, based on interlocking teeth, was invented by an employee of Whitcomb Judson's, Swedish born scientist Gideon Sundback. In 1913 and patented as the "Hookless Fastener" and after more improvements patented in 1917 as the "Separable Fastener". Only after Gideon Sundbach, had remodeled Judson's fastener into a more streamlined and reliable form, was the fastener a success. And the light bulb: Quote: The first electric light was made in 1800 by Humphry Davy, an English scientist. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. This is called an electric arc.
Much later, in 1860, the English physicist Sir Joseph Wilson Swan (1828-1914) was determined to devise a practical, long-lasting electric light. He found that a carbon paper filament worked well, but burned up quickly. In 1878, he demonstrated his new electric lamps in Newcastle, England.
In 1877, the American Charles Francis Brush manufactured some carbon arcs to light a public square in Cleveland, Ohio, USA. These arcs were used on a few streets, in a few large office buildings, and even some stores. Electric lights were only used by a few people.
The inventor Thomas Alva Edison (in the USA) experimented with thousands of different filaments to find just the right materials to glow well and be long-lasting. In 1879, Edison discovered that a carbon filament in an oxygen-free bulb glowed but did not burn up for 40 hours. Edison eventually produced a bulb that could glow for over 1500 hours. Snowmobile I think is a draw:
The Inventor of the Snowmobile Quote: There seem to have been two paths to the invention and development of the modern snowmobile (snow machine, skidoo, snow mobile). Carl Eliason has to be listed as inventor of the snowmobile, since his patent is 30 years earlier than the other contender for that honor, Joseph Armand Bombardier. Carl Eliason of Sayner Wisconsin built what is basically a motorized toboggan in 1924, which was patented in 1927. The other path to development started when Joseph Armand Bomdardier of Valcourt Quebec built his first snow coach in the 1930s. The G-Suit: I don't think so Quote: Inventor of G-Suit Dies
Dr. Earl Wood was Mayo pioneer in aerospace medicine
Monday, March 23, 2009
Rochester, Minn. — Earl Wood, M.D., Ph.D., the Mayo Clinic investigator credited with inventing the high-altitude pressure suit worn by pilots and astronauts, died March 18 in Rochester, Minn. He was 97.
"As both a physician and researcher, Dr. Wood provided nearly five decades of outstanding leadership to Mayo Clinic and scientific advancements to the world," says Denis Cortese, M.D., Mayo Clinic president and CEO. "His achievements made manned spaceflight possible and contributed to American national defense since WWII. His legacy of discovery will benefit society for decades to come." Dr. Wood was born January 1, 1912, in Mankato, Minn. A 1934 graduate of Macalester College, he also earned an additional bachelor's degree, master's degree, as well as Ph.D. and M.D. degrees from the University of Minnesota. After serving as a National Research Council fellow at the University of Pennsylvania, he taught Pharmacology at Harvard University where he met Charles Code, M.D., who offered him a position at Mayo Clinic. SONAR: Quote: Sonar is a system that uses transmitted and reflected underwater sound waves to detect and locate submerged objects or measure the distances underwater. It has been used for submarine and mine detection, depth detection, commercial fishing, diving safety and communication at sea. The Sonar device will send out a subsurface sound wave and then listens for returning echoes, the sound data is relayed to the human operators by a loudspeaker or by being displayed on a monitor.
Daniel Colloden
As early as 1822, Daniel Colloden used an underwater bell to calculate the speed of sound underwater in Lake Geneva, Switzerland. This early research led to the invention of dedicated sonar devices by other inventors.
Lewis Nixon
Lewis Nixon invented the very first Sonar type listening device in 1906, as a way of detecting icebergs. Interest in Sonar was increased during World War I when there was a need to be able to detect submarines.
Paul Langévin
In 1915, Paul Langévin invented the first sonar type device for detecting submarines called an "echo location to detect submarines" using the piezoelectric properties of the quartz. He was too late to help very much with the war effort, however, Langévin's work heavily influenced future sonar designs.
The first Sonar devices were passive listening devices - no signals were sent out. By 1918, both Britain and the U.S had built active systems, in active Sonar signals are both sent out and then received back. Acoustic communication systems are Sonar devices where there is both a sound wave projector and receiver on both sides of the signal path. The invention of the acoustic transducer and efficient acoustic projectors made more advanced forms of Sonar possible.
