Mobile Phone: 40th Anniversary Of The First Call

The world is celebrating the 40th anniversary of the invention of the mobile phone.
On April 3, 1973, Motorola employee Martin Cooper made the first ever call on a mobile phone in New York to competitor AT&T, reportedly saying: “I’m ringing you just to see if my call sounds good at your end.”
It was on a Motorola DynaTAC – a device 9in tall, comprising 30 circuit boards, and which had a talk-time of 35 minutes and took 10 hours to recharge.
Mobile phone technology has come a long way since then – a triumph that has led to years of development, new inventions, and to the creation of the widely-used smartphone.

Hedy Lamarr: Not just a pretty face

How one of the best known actresses of mid-20th century revolutionized weapons systems and helped create cell phones
Hedy Lamarr wasn’t just a beautiful movie star. According to a new play, Frequency Hopping, she was also a shrewd inventor who devised a signal technology that millions of people use every day.
Lamarr—born Hedwig Eva Maria Kiesler in Austria in 1914—developed a passion for helping the U.S. military after walking away from an unhappy marriage to an Austrian Fascist weapons manufacturer in 1937. In an attempt to stall her acting career, he had brought her to his business meetings, where she found herself continuously listening to “fat bastards argue antiaircraft this, vacuum tube that,” explains Lamarr’s character—played by Erica Newhouse—in the play, Frequency Hopping. In the meetings, they had talked about developing detection devices to listen to, and jam, the radio signals that American aircraft and weapons used to communicate with one another; and Lamarr wanted to foil their plans. “Can you guide your torpedo towards an enemy target—or just use radio control period—without being detected? Or jammed?” Lamarr’s character asks.  MORE

Gangs are everywhere, including the burbs, not to worry though 'We Have A Program For That"

Hardcore Gangs Hit Ohio Suburbs GANGS IN THE ’BURBS
Subversive element creeping beyond Columbus’ borders
Last year, Westerville North High School suspended two students who flashed MS-13 hand signs and drew gang insignia during an English-asa-second-language class. MS-13, or Mara Salvatrucha, is a notoriously violent street gang with roots in Los Angeles. It was formed by immigrants from El Salvador.

Gang crime isn’t nearly as serious or common in the suburbs as in some Columbus neighborhoods, but suburban schools and police departments are increasingly on watch.
"It’s not so centralized in the inner city as it used to be," said Pat Brooks, a veteran Columbus police gang unit officer.

Suburban police call Brooks and his colleagues when they suspect gang activity in their jurisdictions.

Most of the crack dealers in Reynoldsburg are gang members who live in Columbus, said Tye Downard, a Reynoldsburg police narcotics detective.
