The Banach-Tarski Miracle

Today’s Spiked Math comic is:




Joke Explanation:

The joke lies in combining the Banach-Tarski paradox with a miracle that Jesus performed:

1. The Banach-Tarski paradox is a theorem that basically says a solid ball (in 3-dimensions) can be split into a finite number of non-overlapping pieces, which can then be put back together in a different way to yield TWO identical copies of the original ball. It doesn’t work in 1 or 2-dimensions though. Wikipedia has a great picture of this:

2. One of the miracles of Jesus was feeding the multitude. Basically the story has Jesus taking five (or seven) loaves and two fish and feeding thousands of people. Jesus took the five loaves and the two fish and looking up to heaven, “he gave thanks and broke the loaves. Then he gave them to the disciples, and the disciples gave them to the people. They all ate and were satisfied, and the disciples picked up twelve basketfuls of broken pieces that were left over. The number of those who ate was about five thousand men, besides women and children.”

Biggest “but you’re wrong” moment?

This one comes from the geek subreddit where user dzudz writes about his biggest “But you’re wrong! You have to believe me!” moment (only counting topics that are scientifically proven to be wrong, nothing up to interpretation):

“Oh god. This one still pains me. In a trivia contest with some of my co-workers, one of the questions was “What is pi to 5 decimal places?”. Easy – I immediately wrote 3.14159 on our answer sheet. Next question.

This is where it gets ugly. One member of our team was the ex-boss
of the company, an old loud guy used to getting his way. He scrubs out
my answer and imperiously announces that pi is 22 over 7, thank you very much.
I start to explain that this is not right, but ALL of my co-workers
have already whipped out their mobile phones and are dividing 22 by 7.
ALL OF THEM.

I try to explain that 22/7 is an approximation that you give to
young students to help them practice fractions, but to no avail. I even
resort to the “I teach maths and am way smarter than you” tactic but it
fails. Somebody writes down what 22/7 is, the ex-boss is smiling
triumphantly at me, and my horror is complete.

Postscript: To demonstrate his superiority, ex-boss then ‘overrules’
every answer I provide for the rest of the night in a similar fashion,
to the awe and accolades of the rest of the team, and we finish a
predictable dead last.”

Quick math joke

Saw this joke on the xkcd forums today posed by Pippin:


Two of my friends in math class today:
“Dude, our slope is so undefined!”
“Straight up, bro.”

Spoiler hint: What is the slope of a horizontal straight line?

Another one from that forum:

Why don’t jokes work in base 8?
Because 7 10 11.

Math pics regarding teachers / students


textbook stuff


“Stuff” is actually a rigorously justified and well defined concept in mathematics, I use it all the time! :P




no cell phones allowed in class


Excellent policy on cell phone use in the classroom. Try this one out teachers. If the class is an upper level class then obviously don’t threaten them with fractions, cause then they’ll laugh at you.




mindgraine


Poor students getting sick over mathematics.
