All this talk of love and physical activity (not related or with anyone who is related) is probably giving the blog world the wrong impression of my true nature. Sure I ride ridiculous distances, love heavy metals concerts but it's what's inside that counts… And inside me is a man in a cardigan and a bow tie screaming to get out.. This all comes back to a joke I saw in New Scientist ( I swear I only read it for the articles), where a instead of the standard "Wash me" or "If Only my wife was this dirty" written in grime on a white car, some jaded chemist has written "couldn't afford the Titanium Dioxide"…
/* warning maths and physics ahead*/
First reason this is funny…. It shows an understanding of the Doppler Effect, common example an ambulance siren changes in frequency as it is coming toward and when it is going away from you, the motion of the sound emitter will change the recorded frequency… Emitter moving in the direction of the wave front, the waves contract, and away from the wave from they lengthen… Changing the observed frequency.. see below.
The formula being
(700*10^-9-400*10^-9/700)C= Velocity of the emitor (or vehicle heading toward)
.42C = Velcoity
.42 of the speed of light.... or .42*1,079,252,848.8 km/h
Obviously not driving my Barina. More a combination wheelbarrow and ride of mower than an actual car..
On a side note...just to mess with your head...
Quantum physics at a very basic level… That you cannot go faster than the speed of light Einstein jumps out with a stop sign and says No… This is due to Lorenz contraction. The faster you go the thinner you become (observed from external) as it becomes thinner, density increases, until object --> approaches -->0 in length and density --> Infinity… Therefore an infinite amount of energy would be required to reach the speed of light (in its most basic terms)
