How did the phrase “Roger that” originate?

How did the phrase “Roger that” originate? #eklectica
In the 1940s, the American military and British RAF used a spelling alphabet different from the current well-known Alfa, Bravo, Charlie.
The letter “R” was used as an abbreviation for “received” back in the times when messages were send via telegraphy (in Morse code), and the practice of confirming that a transmission was received by sending an “R” back was extended to spoken radio communication at the advent of two-way radio during World War II.
The phonetic alphabet used by the British and American military during the World War II was: Able, Baker, Charlie, Dog, Easy, Fox, George, How, Item, Jig, King, Love, Mike, Nan, Oboe, Peter, Queen, Roger, Sugar, Tare, Uncle, Victor, William, X-ray, Yoke, Zebra
When a soldier or a radio operator said “Roger” after receiving a transmission, he was simply saying “R” for “received”.
The alphabet has changed since then, but the practice of replying to a message by saying “Roger” stuck.

How Much Do Expiry Dates On Packaged Goods Matter?Although almost everybody throws out their food once its “sell by” or expiration date arrives, not all of that food is actually bad. Those dates are just guidelines set to help give you an idea of when to use foods—not toss them away.
But more interesting is the story about how these expiry dates came into being!

How GPS Came to Be—and How It May Be Altering Our Brains

How GPS Came to Be—and How It May Be Altering Our Brains #eklecticaWe use GPS today to guide airplanes, ships, and tractors. It keeps tabs on sex offenders and helps find oil deposits. “GPS surveys land, and builds bridges and tunnels,” Milner writes. “GPS knows when the earth deforms; it senses the movement of tectonic plates down to less than a millimeter.” GPS can tell you how long until your Uber arrives—and even let you know if someone nearby is interested in a one-night stand.

The set of technological challenges that had to be solved to enable all of this was formidable.

The History of the Humble Pencil

The History of the Humble Pencil #eklectica
The pencil’s journey into your hand has been a 500-year process of discovery and invention. It began in the countryside of northern England, but a one-eyed balloonist from Napoleon Bonaparte’s army, one of America’s most famous philosophers, and some of the world’s most successful scientists and industrialists all have had a hand in the creation and refinement of this humble writing implement. Sharpen your trusty no. 2 and get ready to take some notes. This is the story of the pencil.

What does the ‘i’ in iPhone really mean?

At an Apple event in 1998, Steve Jobs introduced the iMac, explaining the link between “i” and “Mac.”

Jobs followed these statements with a slide that expanded upon what else the “i” means to Apple:

  • internet 
  • individual 
  • instruct 
  • inform 
  • inspire 
Since then, the “i” has moved beyond its Internet-centric meaning; Apple probably didn’t have the Internet in mind when naming the original iPod.
