Sitting next to a four-year-old on long trips really can run hot and cold.

We did visit a coal mine in West Virginia, by the way.

(x, why?) Mini: Under the Sci...

I prefer to apply Sturgeon's Law to all webcomics, not just to the 1100+ I've written.

By the way, I was just at a Sweet 16 party with an "Under the Sea" theme for the daughter of a couple of friends who go back to my Brooklyn College Science Fiction Society days, which may have played a role and bringing this back to the forefront of my brain.

Hypersphere

RIP2-D2

I was considering this months ago, but because I wanted to do it in a classroom setting and didn't have time before the end of the year, I was saving it for the fall.

However, with the passing of Kenny Baker, the man inside the droid we were looking for, I moved it up and reworked it.

For the record, the Volume inside a 4D hypersphere would be 1/2 * pi^2 * r^4.

Edit Wayne's first dialogue balloon is messed up. Two sentences were combined by accident. It will be corrected as time permits. Oopsie!

Actually, we went South on vacation, not North.

Throwback Thursday: I used a PC with Windows XP and Paint 5.1 to create this one. You use the tools you have not the tools you wish you have.

It's all a matter of momentum and position and energy and ... stuff.

Okay, so, no, I'm really not sure how to explain it, so I'll recommend that you check out a wiki page on Liouville equations.

Daily Regents: Similar Triangles are Proportional (August 2015)

Even though the title says "Daily", I won't be doing them daily any more, until the exams get closer. But they will be frequent.

Geometry, August 2015, Question 27

27. To find the distance across a pond from point B to point C, a surveyor drew the diagram below. The measurements he made are indicated on his diagram.

Use the surveyor’s information to determine and state the distance from point B to point C, to the nearest yard

There are two right triangles. Right angles are congruent.
Both triangles contain angle A. Reflexive Property says angle A is congruent to itself.
Therefore, triangle ABC ~ ADE
If the triangles are similar, then their corresponding sides are proportional.

AE = 230, AC = 230 + 85 = 315. DE = 120. BC corresponds to DE.

Set up a proportion: AE / DE = AC / BC
230/120 = (230 + 85) / x
230 x = (120)(315)
230 x = 37800
x = 164.3478...
x = 164 yards

The distance from point B to point C is 164 yards.
