Thomas Edison Phonograph

This was written during 1877 about his phonograph. The same might be said about social apps and smart phones today.
“He has been addicted to electricity for many years,” the phonograph, with its ability to record speech, “will eventually destroy all confidence between man and man.”

Another paper of the time outlined ways phonographic technology might go wrong: greedy thieves might trick elderly millionaires into vocally amending their wills; sketchy neighbors might use opera recordings to lure women out of their homes; and wives might frighten their husbands out of sleep by playing a tape that yells “POLICE! FIRE!” over and over again. Editorial fear-mongering has not changed much during the past 140 years.

International Year of Light

On 20 December 2013, The United Nations General Assembly 68th Session proclaimed 2015 as the International Year of Light and Light-based Technologies. "An International Year of Light is a tremendous opportunity to ensure that international policymakers and stakeholders are made aware of the problem-solving potential of light technology. We now have a unique opportunity to raise global awareness of this." John Dudley, Chairman of the IYL 2015 Steering Committee

2015 is also the Einstein Centenary. In 1915, the theory of General Relativity developed by Einstein showed how light was at the center of the structure of space and time.

Thought I would toss in a few facts about light.
Lighting represents almost 20% of global electricity consumption.

The first commercially viable incandescent light bulb, patented by Thomas Edison in 1880, used a filament made from burned bamboo.

Other animals can see parts of the spectrum that humans can not, for example, a large number of insects can see ultraviolet light.

The giant squid, Taningia danae, has the largest light-producing organs of any living creature. The lemon-yellow light organs are called photophores and are found at the tip of the two of the squid’s feeding arms and they flash blinding light.

The speed of light in a vacuum is about 186,000 miles per second (300,000 kilometers per second).

Light takes 1.255 seconds to get from the Earth to the Moon.

More than half of the visible sunlight spectrum is absorbed within three feet of the ocean's surface; at a depth of 10 meters, less than 20% of the light that entered at the surface is still visible; by 100 meters, this percentage drops to 0.5%.

Refraction can make things look closer than they really are. The difference in speed between light traveling through water and through air means that, from the surface, a 13ft (4m) pool appears to be just 10ft (3m) deep.

Between 18% and 35% of the human population is estimated to be affected by a so-called "photic sneeze reflex," a heritable condition that results in sneezing when the person is exposed to bright light.

Here is a link to "Light my Fire" by the Doors, just because.

Twelve Patent Facts

On March 19, 1474, Venice passed the world’s earliest known law to grant and protect patents.
Around 50,000 patent applications were made from UK inventors in 2013. That is about one new British invention every 10 minutes.
The Japanese submit more than 470,000 a year.
US patents during 2013 464,573.
The second patent in England was for a monopoly on representing an image of the King.
The musical fly swatter was patented in the US in 1994. It played one tune when turned on and another when it hit something.
IBM has gained more patents than any other company in the US for the past 21 years.
US patent number 5528943, issued in 1996, was for a pregnant female crash test dummy.
Thomas Edison accumulated 2,332 patents worldwide for his inventions.
In 1998, the European patent office reported that the patent visitors most often wanted to see was one for sardine-flavored ice-cream. This was because nobody believed it until they saw it.
Abraham Lincoln was the only US president to hold a patent. It was for a device to lift boats over sandbanks.
There are 52,438 US patents for measuring and testing.

Electrically Charged

Thomas Edison publicly electrocuted dogs and cats in order to demonstrate to people how AC electricity was more dangerous than DC. He even once electrocuted an elephant in order to kill it. The elephant had previously trampled and killed a few people and a method was needed to put her to death, so Edison agreed to do it using AC electricity as a publicity stunt.

Edison is also credited with inventing the electric chair to be used on those sentenced to death, although, it was invented by employees of Edison, Harold Brown and Arthur Kennelly.

Thomas Edison held 1093 patents in the United States. One of his sons, Theodore Edison, who died in 1992 held 80 patents in his lifetime.

Annie Get Your Gun

Phoebe Anne Oakley Mozee was five feet tall. She was also a crack shot with rifles, pistols, and shotguns. Annie Oakley was born in a log cabin in Patterson Township, Ohio and starred in Buffalo Bill’s Wild West Show for seventeen years.

March 5, 1922, Annie broke all existing records for women’s trap shooting by hitting 98 out of 100 clay targets thrown at 16 yards while at a match at the Pinehurst Gun Club in North Carolina. She hit the first fifty, missed the 51st and 67th.

In one day she used a .22 rifle to hit 4,772 glass balls out of 5,000 tossed in the air. She could hit the thin side of a playing card from 90 feet and puncture it at least five times before it hit the ground. It was this display that named free tickets with holes punched in them, Annie Oakleys.

She was immortalized in Annie Get Your Gun, which was later made into a musical for the stage. In 1985, another film, Annie Oakley, was made for TV. It included silent-film footage of the record-breaking sharp-shooter, taken by Thomas Edison. There was also a weekly TV show about her during the fifties.

Why do we say Hello

Thomas Edison wrote a letter to the president of the Telegraph Company in Pittsburgh, PA. In it, he suggested that the word, 'hello' would be a more appropriate greeting than 'ahoy', as was suggested by Alexander Graham Bell for answering the telephone. That is why we pick up the phone anywhere in the world and say: 'Hello, Allo. Alo. Bueno. Pronto. . . wazzup!

Christmas Tree Lights

Edward H. Johnson, who worked for Thomas Edison’s Illumination Company, used 80 small red, white, and blue electric bulbs, strung together along a single power cord, to light the Christmas tree in his New York home in 1882. Some sources credit Edison with being the first to use electric lights as Christmas decorations, when he strung them around his laboratory in 1880. It was three years after Edison had demonstrated that light bulbs were practical.

Edison Sounds

Here is an interesting site LINK that has some recordings from 1899 forward. Interesting funny bits, songs, educational lessons, etc. Fun diversion for the nostalgically inclined., brought to you by the National Park Service and Thomas Edison's recordings.

A Hundred Years Ago

1910 Thomas Edison demonstrated the first talking motion picture.
Georges Claude displayed the first neon lamp to the public on December 11, 1910, in Paris.
Fifty years ago, 1960 - The halogen lamp invented.
