GPS Would Be Impossible Without the General Theory of Relativity​

Some 10,900 nautical miles above our heads, 31 satellites orbit Earth as part of the Global Positioning System (GPS) — but if it wasn’t for Einstein, those satellites would be little more than space junk. The very foundation of GPS is accurate timekeeping, as satellites need to keep time to correctly log the distance from a ground-based receiver (such as your smartphone). GPS satellites are so precise, the atomic clocks on board are accurate to within three-billionths of a second, a feat impossible without Einstein’s special and general theories of relativity. The special theory of relativity states that time flows differently depending on velocity. Because satellites travel at 8,700 miles per hour, they “lose” 7 microseconds per day compared to Earth-based receivers. Additionally, Einstein’s general theory of relativity — an idea published in 1915 that basically elaborates on his previous theory by throwing gravity in the mix — similarly states that distance from a source of mass, in this case the Earth, also affects the flow of time. This means that technically speaking, your head ages slightly faster than your feet because your feet are closer to the Earth (on time scales that are ultimately negligible). Today, GPS takes into account this “time dilation,” so satellites always know where you are when you open Google Maps.

And yet GPS has still let me down; I've been steered into an empty field on the wrong side of the highway when looking for a business.
 
There are 110 trillion mosquitos in the world. They outnumber the human population 16000 to 1. Some estimates the global mosquito population could be in the quadrillions.

I managed to get stranded in the middle of nowhere about 12 years ago due to several road closures due to fire and car crashes. One of the Cops in attendance said I could follow themm as they were heading back to their station....and they had a GPS. Well after about 30 mintes of driving back-country gravel roads, he stopped.....he got out and said that the GPS said to perform a U-turn.
That was quite fortunate, as the next stop would have been the east coast of Australia. :lol:

That's awesome. Reminds me of a Drag Meeting I helped organise back in January 2000 - called "Uncle Sam meets the Rising Sun". Billed as an all-inclusive meet for the ricer boys to race the V8 crowd....it ended up a decent meet with a lot of cars racing.
One local celebrity /TV Comedian - the late Ewan Gilmour decided to race his Tour Bus - a large Camper Van.....nothing special, but being a Westie Bogun, he gave it a shot. He managed a time of around 24 seconds for the Quarter.

At prize-giving we had a load of product, but I had also made a few trophies in anticipation....one of them being for the "Slowest ET of the Day"

Ewan was presented with the trophy and he took it with a huge smile and much appreciation. I had made a Sun Dial out of an old 440 piston, and marked a few numbers on the top ranging from about 12 - 25.

April 1 2006 was my very first day going to work for Layson's.....been 19 years as of today.....and I'm still "somewhat" sane......according to some people anyways....:realcrazy:


April 1 2025......according to Social Security, I am now at "Full Retirement Age", so I can legally sponge off of the gov't 'till I die and not feel guilty about it :lol:

I borrowed a GPS unit from a friend for a service call. Worked fine for what I needed.
For giggles, I turned it on a mile from my house on my way home. It directed me in the exact opposite direction, and then installed me in an unending loop around the block..... RT turn here, rt turn here, rt turn here, etc.
....three blocks from my house. LOL.
 
Graham Barker's Collection

He now has three bottles of BBF, generated at 3.03 mg per day, or about 1.1 grams per year. Over fifteen years of Belly Button Fluff collected by Graham Barker. In November 2000, the Guinness World Records officially recognised his collection as the largest collection of BBF in the world.

In 1983, GM skipped producing a Corvette available to the general public.

BUT, one 1983 Corvette unicorn sits in the Corvette museum in Bowling Green. Not ever intended for sale, it was one of a run of 43 pilot assembly mules built when the 1983 Corvette was still in planning, in June 1982. After production was delayed until 1984, the rest of the cars were scrapped, so this is the only 30th anniversary 'vette still existing.

Yup, I read that somewhere too. I'm not a big Corvette fan, otherwise I may have run across that bit of trivia sooner:D
