"Every H₀ down in Math-ville liked Mathmas a lot
But the Grinch, who lived (x-100,y+20,z+1300) from Math-ville, did not!
The Grinch hated Mathmas! The whole Mathmas season!"

"On the nth, n ε Z, n ε [1,...,12] day of finals, my TA gave to me...
n = 1: a bell curve to make sure I pass!
n = 2: two painful proofs
..."

"Operations Research: Really, what are they researching? Certainly not good Christmas gift ideas, like me! What you really want to get them is a spy kit! Something like... Magnifying glasses and a detective hat, to help them research with more awesome attire!"

"What Function's This?

(To the tune of "What Child Is This?")

What function's this? When added to
c times its derivative gives me
An f(t), oh how can we
Solve this first order DE?"

"Once upon a time there was a theorem known as Squeeze's Theorem. This theorem wasn't particularly nice at all. In fact, he would pinch functions and force them to converge. He never celebrated Mathmas. However, all of that was going to change on this: Mathmas Eve."

"Q: Why do mathematicians often confuse Christmas and Halloween?
A: Because Oct 31 = Dec 25.

Q: What's purple, round, and doesn't get much for Christmas?
A finitely presented grape."

"Oh, Calculus; Oh, Calculus,
How tough are both your branches.
Oh, Calculus; Oh, Calculus,
To pass what are my chances?
Derivatives I cannot take,
At integrals my fingers shake.
Oh, Calculus; Oh, Calculus,
How tough are both your branches."

"Riemann Sums
(sung to the tune of Jingle Bells)

Riemann Sums, Riemann Sums
Counting Areas
Of rectangles whose widths get small
We need to count them all
Riemann Sums, Riemann Sums
Counting Areas
Of rectangles whose widths get small
We need to count them all."

"I recorded this during my AP Calculus Class right before the holiday seasons. And when I say we are Math geeks this will prove it to you!!! Muhahahaha!!!"

"I wrote this proof on the blackboard my first year teaching in an 8th grade honors math class in the last five minutes of class on the day before Christmas break. Strangely, now that I teach in high school, I haven't been able to use it as I'm never at the right point in the curriculum for them to follow the "logic"."

"Christmas is about more than the giving and receiving.

It's also about the baking and the eating."

"Here we go sing it loud, we're counting by ones Try and keep up, we're having so much fun We're starting at one and counting all the way to fifty Now don't skip a number when you're singing with me

One, Two, Three, Four, Five Six, Seven, Eight, Nine, Ten Eleven, Twelve, Thirteen, Fourteen, Fifteen Sixteen, Seventeen, Eighteen, Nineteen, Twenty Twenty One, Twenty Two, Twenty Three, Twenty Four, Twenty Five Twenty Six, Twenty Seven, Twenty Eight, Twenty Nine, Thirty Thirty One, Thirty Two, Thirty Three, Thirty Four, Thirty Five Thirty Six, Thirty Seven, Thirty Eight, Thirty Nine, Fourty Forty One, Forty Two, Forty Three, Forty Four, Forty Five Forty Six, Forty Seven, Forty Eight, Forty Nine, Fifty"

"The Four-Color Theorem (4CT) dates back to 1852, when it was first proposed as a conjecture. Francis Guthrie was trying to color the map of counties in England and observed that four colors were enough. Consequently, he proposed the 4CT. In 1879, Alfred Kempe provided a "proof" for the 4CT. A year later, Peter Tait proposed another proof for 4CT. Interestingly both proofs stood for 11 years before they were proved wrong. Percy Heawood disproved Kempe's proof in 1890, and Julius Petersen showed that Tait's proof was wrong a year later.

However, Kempe's and Tait's proofs, or attempts at a proof, were not fully futile. For instance, Heawood noticed that Kempe's proof can be adapted into a correct proof of a "Five-Color Theorem". There were several attempts at proving the 4CT before it was eventually proved in 1976. See this article by Robin Thomas for a historical perspective of the problem."

Hunch is a new way to help people make all kinds of decisions:

• Where should I go on vacation?
• What kind of phone is right for me?
• Which museum should I visit in Canada?
• What blogs should I read right now?

Results are based on the collective knowledge of Hunch's users. It asks you 10 questions to answer then gives you results. If you don't like the results, you can train Hunch to learn from its mistakes :-D

So the next time you are stumped on a tough decision, let Hunch decide for you!!
