Maths

It's apparently National Maths Day today (seem to have a day for everything).  Now, where did I put my slide rule?

There doesn't have to be an infinite number of planets, inhabited or otherwise; the point is that there's no reason there isn't. That was the flaw in the given argument.

OG, the first sentence claims, "It is known that there are an infinite number of worlds, simply because there is an infinite amount of space for them to be in." (emphasis added)

it's funny that maggie has not returned to this thread.

[maggiebee]

Haven't returned TTT as I've no idea what you are all talking about.  Don't even know how to use a slide rule - it was posted tongue in cheek.

"So the number of inhabited worlds is also infinite but that infinity is smaller than the infinity for uninhabited worlds."

Why is the number of inhabited planets smaller than the number of uninhabited ones?

This is when most of us go off maths!   

There used to be a practical CSE exam on 'Arithmetic' - you know, the useful stuff that everyone needs every day.  Kids who got that could get jobs - and most did.  This basic exam needs re-instating for all.  Those good at Maths go onfurther....fairly simple.  Currently Maths turns alkot of kids of.

Maths is a total turn-off for the majority of kids.

"Maths is a total turn-off for the majority of kids." - which is why we are heading for an "Orphans of the sky" (Robert Heinlein) situation.

Space isn't infinite, though it is expanding at a greater rate
