I practice talking sometimes.

It's a little funny that way: I've worked over the air before, but I have such little confidence in my voice. I stutter. My lips or teeth or jaw have always felt awkward, and I'd even seen a speech therapist when I was young. The braces didn't help, and the full implications of "JAW SURGERY" hit me all at once about a month before it was supposed to happen. I'm also first-generation Canadian, and my parents have never been great with English. I don't know if that's why I took to music and drawing and literature and Math so eagerly.

I've always had a thing for expression, for communication. Anyone who knows me will also know I have a crush on Math for that very reason--among others.

I love that, in Math, any aspect of life or any thought can be modeled using these strange symbols and even stranger rules, both of which can be taught to anyone; ideas can be communicated, proven, or disproven, and even improved upon by any number of people also seeking to find the most perfect expressions.

It's a whole community devoted to perfect universal truths.

... Hehe!

Concavities and Venn Diagrams

Concavities!

I'm subbing in for the Calc teacher at Maths School on 02-Feb and 09-Feb. He wants me to cover Concavity. As soon as I finish with a proof of concavity, I'll post it up here.

For now, you get this Venn Diagram as I ponder over Necessary and Sufficient. ...Again. Augh!

Venn Diagram showing relations of odd numbers, prime numbers and even numbers.

I'm not sure who else got taught this way, but I was taught that the rectangle (in this example) is "The Universe", so label accordingly! Put a title on The Universe! Label things that aren't in the circles!


Mm, tired.
