Good video for math educators

Jun 2, 2010  
In this TEDTalks video, Dan Meyer talks about how today's math curriculum is teaching students to expect and master paint-by-numbers classwork, robbing kids of a skill more important than solving problems: formulating them. He then talks about classroom-tested math exercises that prompt students to stop and think.

It's a good watch for any educator in mathematics.

If you haven't seen the video above yet, it's a video by Matthew Weathers who teaches in the Math Department of Biola University, a private Christian university in a Los Angeles suburb. In it, he does a little joke for the students in his math class.

He also has a halloween video from last year which is rather entertaining:

How to: organize your digital library of papers

Oct 29, 2009  
There are a few ways you can organize the digital papers you download.

1. One such way is using Zotero. Basically, Zotero [zoh-TAIR-oh] is a free, easy-to-use Firefox extension to help you collect, manage, and cite your research sources.

zotero.jpg
2. Another one is to use Mendeley. In addition to being multi-platform, it also has a web site where you can sync your PDFs for online access. It also extracts the metadata from your PDFs (like title, authors, journal titles) and fills in many fields for you. You also have PDF renaming options.

3. Finally, a lot of people use papers: http://mekentosj.com/papers/

I haven't tried any of these though, so I wouldn't know which one to recommend. I personally just organize the PDF's by fields of research and name each one as the title of the paper. It helps having hard copies as well :D

Balloon boy fail (do the math)

Oct 19, 2009  
Ya so I keep hearing about this balloon boy... although I haven't actually read any news articles on it, so based on headlines I keep seeing this is what I suspect happened:
- Richard Heene makes experimental helium balloon
- Heene & wife freakout since their "son" may be in the basket
- crapload of publicity, balloon comes down, son not in there
- son was actually in the Heene house attic all along
- 4chan delivers pizza to balloon boy
- news now reporting the stunt was a hoax
- charges filed against Heene
So what does this have anything to do with math? Well I came across this post about someone doing the "math behind the balloon boy story". Basically they do some fancy calculations to see if it was ever possible for such a crappy balloon to lift a small boy:

"Was it ever even possible that a 20' x 5' helium balloon could lift the weight of a six-year-old to 8,000 feet MSL? Let's take a look at some numbers. Taking Falcon Heene's father at his reported word, the balloon that news helicopters followed for two hours Thursday (because they thought Falcon was aboard) was 20 feet by five feet. We don't know if that included the compartment at the bottom -- so let's be conservative and assume it did not."


You can find the rest of the post here.

Look around you maths

Oct 8, 2009  
This British comedy show is hilarious. It's called "Look Around You" and the second epsidoe is about "Maths". Check it out on youtube (at least for now):

look.jpg
Quote from the show (but you really have to watch it to put it in perspective!!):
"Narrator: What's the largest number you can think of ?
Person 1: 100,000
Person 2: 999,000
Person 3: a million!
Narrator: In actual fact it's neither of these. The largest number is about 45 billion, although mathematicians suspect there may be even larger numbers!"
And one of the problems they presented:
"Narrator: Eight ladies go to eight shops at eight o'clock in the morning. Each lady wants to buy eight spiders. For each spider, eight spider shoes must also be bought. But they only have eight pounds between them. With each spider costing eight pence and each spider shoe costing an eighth pence each, will the ladies have enough change for the bus ride home? A journey costing eight pence per stop and made up of eight stops."
Check out the wiki entry for more information.

After five minutes of struggling, she FINALLY managed to get it right.

How to Compute Cubed Roots Fast

Aug 9, 2009  
Take a look at this video of Scott Flansburg on the Discovery Channel's "More Than Human":

Scott Flansburg takes cubed roots fast

In the video you see Scott Flansburg take the cubed root of 658,503 to get an answer of 87 in a matter of a second. How does he do it you ask?
This trick does require some memorization though, and also requires the number given to be a perfect cube. You need to memorize the cubes of the numbers 0 through 9 (or be able to figure them out on the spot). This information is contained below:

cubed2.jpg

Note that the last digits of the cubes on the right have all the numbers 1 to 9, but no number is repeated. Here is how to find the two-digit cube root of a perfect cube.

Take a number, such as 658,503 which is grouped into two parts.

1. Looking at the number we see it ends in a 3, and according to the table only 7^3 ends in a 3, thus the last digit of our number is 7.

2. Next, ignore the last 3 digits of the cube, so consider 658. Compare these digits with the table above. Note that 658 fits between 512 and 729. You always choose the smaller one, in this case 512 which happens to correspond to 8^3.

Thus, the last digit is 7 and the first digit is 8, giving an answer of 87.

Normally this trick is used for six digit perfect cubes. To help understand how this works, ask yourself - What is the last digit of (10x+y)^3? Clearly it is y^3 mod 10 (how does this relate to #1?).

Another Example:
In 474,552 we have that 343 is the immediate smallest number from 474 so the first digit is 7.
The last digit in 474,552 is 2 and only 8^3 ends in a 2, so the last digit is 8. Hence, 78^3=474,552.

Why is life expectancy higher in Canada?

Aug 4, 2009  
Taking a look at the table in wikipedia the life expectancy for Canada is indeed a bit higher than that of the USA. Peter Gillies asked this question and Bill O'Reilly answers it perfectly:
"Well, that's to be expected, Peter, because we have ten times as many people as you do. That translates to ten times as many accidents, crimes, down the line..."

The Human Calculator - Scott Flansburg

Aug 1, 2009  
  • Scott Flansburg was born in New York on December 28, 1963.
  • He served in the U.S. Air Force (1982-1988) and had a tour of duty with the Office of Special Investigations in Tokyo, Japan. He then returned to the United States and became an advocate of teaching math in an innovative fashion. 
  • In 1989 he drew the attention of Regis Philbin. Mr. Philbin is the individual that is credited for naming Scott, The Human Calculator during his appearance on The Regis and Kathy Lee Show. 
  • In 1991 he began working on a project called Turn On the Human Calculator In You, a series of tapes that was subsequently on Mike Levy's Amazing Discoveries.
  • Turn On the Human Calculator In You was one of the most successful early infomercials touted as having in excess of 125 million viewings.
  • The follow-up product was called Mega Math with Kevin Tredeau (1996) which added a video and workbook and was later published by Tru Vantage International.
  • He has subsequently appeared on countless television shows including Oprah, Ellen, The Tonight Show with Jay Leno, Good Morning America, Discovery Channel's `More Than Human', and thousands of local radio and TV shows.
