Frazz by Jef Mallett for April 21, 2015

Too much “Star Wars”, they watched.

Yoda-speak they are stuck in!

Fusing, this punchline is con-.

This is the kind of convoluted speaking up with which I will not put.

I’d think Frazz’s line would be “understand me, mis-, you did.”,,,, which I like anyway, cos it serves for a pun….

Didn’t do well in math did you?

Richard Russell: the punchline is “yeah, right”.

> How do you get a negative times a negative > equal a positive? You can’t.

Aaaand the universe folds and ceases to exist.

Two wrongs don’t make a right, but two Wrights make an airplane.

I guess I’m missing the joke? A negative times a negative is always a positive. -2 x -2 = 4 -2 + -2 = -4

You think Yoda stops teaching, just because his student does not want to hear? A teacher Yoda is.

- Yoda

There’s a linguistics professor who starts her lectures about word order in different languages with a screenshot of Yoda. It really works in getting the students’ attention, and the examples are easier to follow than awkward translations of Chinese or whatever.

" @comicsssfanWho would ever pay attention to a comment from a product of your school system?Get serious; did you learn something … or not?".He did. Somehow, you might not have. .Or were you not completely ‘there’ in your math class?

All of them. When you look at a phase diagram, plotting temperature against pressure, three regions are shown, describing the limits for gas, liquid & solid. There is a line that shows the boundary between liquid and solid at various pressures. “Freezing point” is where something can be in either state, adding or subtracting energy at that pressure will take it away from that line. In your freezer, take a look at a partly frozen ice cube. It’s all at the same temperature, bit some is frozen and some not. It takes energy to convert from a solid to a liquid, but it is all at the "freezing point. All elements do this, and most compounds.

When dealing with algebra, my math teacher never let us say -x as “negative x”, it was always “the opposite of x”. Because, X might be a negative number, and -(-2) would be the opposite of negative 2 = positive 2. It also helps to think of it as its own operator (like * or +) that automatically changes the sign. Since you can multiply in any order: -2*-2 is the same as "the opposite of the opposite (double negative) of 2*2. Finally, 2*2=4. The opposite of that is -4, and the opposite of that is 4. Two negatives multiplied become positive.

The right to freedom of religion to destroy the rights of others is negative.

If you have MS windows, run this in the calculator:(0-1) * (0-1)

If anyone is interested, here is a simple algebraic proof that a negative times a negative is positive:

Let a and b be any two real numbers. Consider the number x defined by

x = ab + (-a)(b) + (-a)(-b).

We can write

x = ab + (-a)[ (b) + (-b) ] (factor out -a)= ab + (-a)(0)= ab + 0= ab.

Also,

x = [ a + (-a) ]b + (-a)(-b) (factor out b)= 0 * b + (-a)(-b)= 0 + (-a)(-b)= (-a)(-b).

So we havex = ab

andx = (-a)(-b)

Hence, by the transitivity of equality, we haveab = (-a)(-b)
