Is there a simple to use online International route finder? Like the AA routefinder, but Global.
Say I won a bit of money and I wanted to go buy a new Porsche and drive to (say) Malaysia (stopping off a few times on the way
) could I plan my route online by typing start point: <Somewhere> in the UK, End point: <Somewhere> in Malaysia?

Why on google maps when you try drop the yellow guy for street view does he just fly back to where you dragged him from?and then repeat this for ages until he either just gives up or eventually does enter street view?
You can only drop him on the roads that turn blue when you click on him.They don't have images for the other roads so he just flies off.

Why does time exist?
Er...Do you mean why is everything in the universe not static? Why do electrons carry charge?
Or why do we observe the fact that events progress, and measure it?
The cup is actually in four dimensions, and when you drop it on the floor and it breaks into pieces, you are simply witnessing its fourth dimension from the third.
Before the universe existed, so far as we know, there was no time- since time is a measurement of changes in state (cup in air->hitting the ground, sun going out, etc) Eventually, given enough time, all of the energy in the universe will have reached equilibrium and time will become meaningless as there will be no change in state, and thus nothing to measure.
This is expected to happen not before 10^100 years.
When you start thinking about this, arguments about politics start to seem really stupid.

This sort of statement makes me really uncomfortable as it exposes the limits of my ability to understand the subject. I simply can't grasp what "dimension" means beyond the simple manifestation of up, down and across. "Witnessing its fourth dimension from the third" sends my brain in to a spin. I think it would take a very good teacher a very long time to get me to understand it. Kudos to folks who manage to get this stuff.glazbagun said:
Following on from the soap question- why do carbs stick to things so well? I'd forgotten to clean my breakfast bowl yesterday and this morning getting the weetabix off was like cracking concrete!
Because it's soft when moist so moulds to the bowl, excluding any air. Once it's dry you have to overcome 15lbs sq inch atmospheric pressure to shift it.Dr Jekyll said:

always rinse it off, if you know what's good for you! (OK!)

Not necessarily. You have three options (best thought about from the perspective of an expanding/contracting universe):1. Equilibrium - the universe keeps expanding but slowing down eventually reaching equilibrium.
2. Eternal expansion - keeps expanding - no equilibrium, increasingly lonely.
3. Big crunch - opposite of the big bang - universe expands hits a limit, then contracts again.
And sort-of a 4th: Oscillation - some contracting and expanding either forever or followed by one of 1-3.
It's all in a brief history of time, which apparently everyone owns but has never read.
This is quite good too:

Flour is made from wheat.
Essentially Weetabix is bits of wheat stuck together with glue made from smaller bits of wheat.

Where does the ocean's salinity come from?
An average male Blue Whale releases around 16 litres of semen in each ejaculation. There are a lot of Blue Whales in the ocean. You figure it out.
There are only about 10-25K blue whales, of which somewhere between 4.5 and 11ishK are male and post-puberty. They haven't been observed to 'spontaneously ejaculate' (i.e. shoot one off when not bonking or, I dunno, using a kayak as a fleshlight or something), so it may mostly just be when mating, although we know so little about what they get up to or even where they are that they could frankly be having massive cetacean homosexual orgies in the Mariana trench and we'd be none the wiser.
Assuming a generous 1 wet (ahaha) dream per mature blue whale bull per day, which is actually pretty unlikely because making that much spooge has a high energy cost when cows only come into oestrus once every two or three years… I digress. Ten thousand bull whales times 365 days times 16 litres is juuuust over 1 x 10^8 litres a year. Which is a f
k of a lot of whale jizz. Except. First, there is 1.6 x 10^21 litres of water in the world's oceans - for every litre of whale juice, there's 16 000 000 000 000 litres of water. Think homeopathy - even if all of it was just sloshing around rather than being immediately snaffled by various microfauna, who in evolutionary terms are far too clever to pass up on a high-calorie, high-protein snack when it floats past their mostly not literal noses - there'd be so little of it around as to basically just not count. Bear in mind I may have overestimated by many orders of magnitude here, too, not least that that 16 litres quote is pretty dodgy given that blue whale testes are only about 12 kg each. /cetacean biology nerd
