Did you know.....?

Did you know why there's a silent K on words like know and knight?


Because we actually used to pronounce the k (like knight comes from a german word kernicht (or something) (thanks suzie dent). When i hear stuff like this i don't get people who go on about language and grammar accuracy trying to preserve a dessicated snapshot of a language from the 19th century (slang is the evolution of language (imnsho))
 
Knight Knife Knee knickers knowledge, they are not pronounced because people got tired of saying the K... so they just took it out and it evolved to saying it without the K

Same with words like Knock and R.I.P,

Naw I'm pretty sure it was fairly recent.. was probably the apple one i was talking about as i remember it being a lot older than the one you posted.

Watched an hour-long talk on the history of high speed imaging on PooToob just the other day which covered all this - mainly focussing on the fella who took that famous pic of a bullet piercing an apple (and bullets sliciing playing cards and puncturing balloons and lightbulbs and the like) but also back to the very early days of photography (Maybridge proving all four of a horses feet leave the ground when galloping) and right up to date with techniques similar to those described in that TED talk I linkied. Was interesting stuff (and amazing pix) but buggered if I can find it now :!

You mean this one?

That was taken 60 years ago which is rather incredible actually. Anybody fancy offering a guess as to what will be achievable in another 60 years?
 
There will be nuclear bullets that can destroy cities

Check out the CIA heart attack gun

In 60 years the world will be beyond what we can imagine atm

They'd be big bullets cos you need a certain amount of fissionable material and don't think you can skimp on it hugely through technological means, no? Dunno about fusion bombs (or indeed bullets). It's a lot trickier to get right but having a small sun appear in a city would probably cause a bit of a kerfuffle.

Most definitely.

Did you know in the 80s construction began on the 'Superconducting Super Collider' (particle accelerator) in Texas, which would have had a tunnel 84km long & required 99 trillion volts to operate. However, the build was scrapped by Congress after $2 billion dollars had been spent on digging a 22km stretch of tunnel.

In the words of Bill Bryson:

CERN are apparently considering extending the LHC to 100km once they've gone as far as they can with the current version. Plans have been drawn up but still up in the air whether it will ever actually happen for several reasons.

Vending machines go back to ancient times. The ancient Egyptians and Greeks had them. Probably had less Coke marketing around 'em though. Records indicate that American tourists were still dying en masse trying to get snacks even back then though.
 
^ Well how times change... you never know... we find new methods every year for lots of different items, it was though it's impossible for anything to go faster than light... but here we are in 2014... with new theory's, in 1950 it was though it would take hundreads of years to reach the moon... 10 years later they landed

Now 60 years from now... 2074... we will likely be walking on mars, there are already tickets being sold to go to mars in 2030 - 2040 by Virgin

The moon thing was a unique set of circumstances. Rocket technology from WWII meets emerging Cold War paranoia, prestige and arms race. Without that it probably would've taken hundreds of years (well, tens certainly). Still nothing on the horizon for FTL travel either despite popular science shows at the more populist end wheeling it out over and over again. They forget to mention that everything described doesn't actually work even theoretically in the 'real world'.

Guessing the future is a mug's game anyway. Interesting but almost guaranteed to be waaaaaaaaaay off the mark as your quotes demonstrate.
 
4.9 recurring is the same number as 5

x=4.999999...recurring ergo the numbers go on forever
10x=49.99999.....recurrring ergo the numbers go on forever.

subtracting the first equation from the second...

9x=45.0 (everything after the decimal places cancel as they both go on forever and are therefore by definition the same)

simplify to

x=5

therefore...

4.9999...recurring=5

Q.E.D
 
There's actually a way of discrediting that pardoxical proof I think but I can't remember what it is. I've forgotten most of my maths.
