A Venn Diagram of the Real Number System


Joseph Nebus reblogged this on nebusresearch and commented:

I'm aware that it isn't properly exactly a Venn diagram, now, but the mathematics-artist Robert Austin has a nice picture of the real numbers, and the most popular subsets of the real numbers, and how they relate. The bubbles aren't to scale --- there's just as many counting numbers (1, 2, 3, 4, et cetera) as there are rational numbers, and there are far more irrational numbers than there are rational numbers --- but if you don't mind that, then, this is at least a nice little illustration.

Raise your hand if you've had a rough year.

Yep, that’s what I thought.

It’s been a rough year for us, too. I feel like a broken record, seeing as I said almost exactly the same thing last year. 491 more words

Venn Diagrams, Algebra and the New GCSE

I’m a fan of Venn Diagrams (and the more versatile, lesser know Euler Diagrams), and the uses they have when dealing with probability. I was glad to see then installed in their full glory to the new GCSE curriculum. 229 more words
