Mathematics made interesting

[flymo]

Fascinated by numbers? take a look at this video, mind blowing when you consider the consequences of what he is saying.

Think about energy usage, food consumption, population growth etc.

there are additional parts to watch on Youtube

"The Exponential function is used to describe the size of anthing that growing steadily, for example 5% per year"

ha ha, the first 30 seconds dont reveal the importance of the remainder. A few interesting stats start to reveal the consequences of the numbers....

Something (anything) increasing by a uniform percentage of 7% per year will double itself in only 10 years. 'So what' you might think, but when you consider how that applies to many things in everyday life it really makes you think.

That was just the most fascinating lecture! I'm going to have to find the other 7 parts to watch now. Damn, as if I didn't have enough to do already!

lol i will watch it when i get a moment dude :)

All a bit obvious really.

Makes me think of the Menger Sponge.

Mindboggling. The ultimate iteration of a Menger sponge has infinitely large surface area, and infinitely small volume, so it's vast, but doesn't take up any space. Fantastic.

Georg Cantor's work into infinities of differing sizes is something that always makes my head spin too

Bit like my mate's ego! Massive volume but teeny weeny ickle brain ;)

[The Idle Biker]

this is terrible, we are going to be fooked unless we find new mathematic rules. when are the mathematicians going to sort it out?!

[Biker Biggles]

Interesting stuff.
Puts a whole new angle on the term sustainable when you think that there are more people alive today than have ever lived throughout history.

Sounds like a 3d fractal? closest thing we got is aerogel :D

Ish - it's stunningly simple in construction principle for something so weird in actuality.
