Facebook sucks at math

I was goofing off on Facebook when I decided to look into it’s advertising system. I got to a page that asked for a bunch of information. I decided to target people with the following particulars:

  • 18+ years old
  • College Grad
  • Majored in Mathematics (of course :D)

It also asked for countries to target. I put in Canada and the United States and at the bottom of the screen it said:
164,400 people

  • who live in one of the countries: Canada or United States

Then I decided I would add China to the list of countries. The reason
for this is because I wanted to target MORE people!! But as soon as I
added China, the bottom of the screen said:

161,260 people

  • who live in one of the countries: Canada, United States or China

facebook-fail-2.pngBy adding China, the number of people went down! Epic FAIL on Facebook’s behalf!

Cool game – 20 questions – and how it works

Twenty Questions is a popular game which encourages deductive reasoning. Usually, one person is chosen to be the answerer. That person chooses a subject but does not reveal this to the others. All other players are questioners. They each take turns asking a question which can be answered with a simple “Yes” or “No”. Lying is not allowed, as it would ruin the game. If a questioner guesses the correct answer, that questioner wins and becomes the answerer for the next round. If 20 questions are asked without a correct guess, then the answerer has stumped the questioners and gets to be the answerer for another round.


20 questions

The above game is called 20Q and you can play it online at 20Q.net.

Now for some math:
The
game is often used as an example when teaching students about
information theory. Mathematically, if each question is structured to
eliminate half the objects, 20 questions will allow the questioner to
distinguish between 2^20 or 1,048,576 objects. Thus, the best strategy
for 20 Questions is to ask questions that will split the field of
remaining possibilities roughly in half each time. This process is
analogous to a binary search algorithm in computer science.

Top 10 list of geeky math comics / webcomics

I’m a math geek, so I enjoy reading the occasional comic strip that’s math related. Here is my list of the top 10 webcomics/comics that I read on a regular basis:

1. Foxtrot – Surely, everyone knows this one. It occasionally has a lot of math humor but is currently on a Sunday only publication schedule.

2. xkcd – Updated every Mon, Wed, Fri, and a very popular webcomic online.

3. Abstruse Goose – Funny webcomic updated regularly, but often physics related as well.

4. Spiked Math – New daily webcomic in color (this should be on the top of the list since I created it ;-))
5. (x, why?) – A funny webcomic, and has over 350 comics published to date.

6. Brown Sharpie – Updated every Mon, Wed, Fri, and can be quite humorous.

7. Brightly Wound – Often contains physics and astronomy as well.

8. twisted pencil – Usually updated Tue/Thu and contains lots of puppets.

9. mathTICS
– Usually has some pretty funny strips. Not sure if the author is as
active right now and the archive only has the first 100 strips.

10. Indexed – Interesting concept. Mostly consists of venn diagrams and graphs.

Sex Math Jokes

When Noah’s ark had finally come to a rest on top of mount Ararat,
and when the waters had receded, Noah and his family – along with all
the animals – left the ark, and God told them to be fruitful and
multiply upon the earth.

But after all those months under deck on an overcrowded ark, none of
the animals was in the mood for sex anymore. Noah, who knew all too
well what God could do in his wrath if his creatures were disobedient,
got desperate.
So, he tore down one of the ark’s masts, cut it into pieces, and
built a table out of the logs. Then he told one of the snakes to
perform a lascivious dance on top of the table and made all the other
animals gather around it. After a while the snake’s seductive moves
showed an effect: One animal after the other started rocking in the
rhythm of the snake’s dance, and one after the other sneaked off with
its mate to more private places… Finally, the dancing snake and her
mate were all alone, and they too disappeared.

And Noah was pleased that God’s will would be heeded.

Q: What does this story from the book of Genesis teach us about math?
A: When you have to multiply, all you need are a log table and an adder!


A mathematician gives a talk intended for a general audience. The
talk is announced in the local newspaper, but he expects few people to
show up because nobody who is not a mathematician will be able to make
any sense of the title: Convex sets and inequalities. To his surprise,
the auditorium is crammed when his talk begins. After he has finished,
someone in the audience raises his hand.

“But you said nothing about the actual topic of your talk!”

“What topic to you mean?”
“Well, the one that was announced in the paper: Convicts, sex, and inequality.


A professor of mathematics sent a fax to his wife. It read:
“Dear Wife:
You must realize that you are 54 years old, and I have certain needs
which you are no longer able to satisfy. I am otherwise happy with you
as wife, and I sincerely hope you will not be hurt or offended to learn
that by the time you receive this letter, I will be at the Grand Hotel
with my 18-year-old teaching assistant. I’ll be home before midnight.–
Your Husband”

When he arrived at the hotel, there was a faxed letter waiting for him that read as follows:

“Dear Husband:
You, too, are 54 years old, and by the time you receive this letter, I
will be at the Breakwater Hotel with the 18-year-old pool boy. Being
the brilliant mathematician that you are, you can easily appreciate the
fact that 18 goes into 54 many more times than 54 goes into 18. Don’t
wait up.”
