What’s so special about the number 2520?

I meant to get around to this sooner, but I was intrigued by the Assistant Village Idiot’s posts from a few weeks ago about the Southern Poverty Law Center and their list of hate groups.

I was going to write a post on the SPLC tonight, but my throat seems to have caught fire and my sinuses appear to be attempting an evacuation….so instead please enjoy this video of math majors dancing:

Happy St Patrick’s Day!

I’ve got some pretty good Irish heritage going on in my house.  In fact, I’m the least Irish member.  The dog is actually an Irish immigrant, the husband’s completely Irish.  The little lord has more than me, and (in the words of my mother) I’m a mutt…albeit a mutt with a good helping of Irish.

Anyway, living in Boston I tend to forget that Irish heritage is not ubiquitous in the US.  I found this map that shows that my skewed vision is at least somewhat justified:

It appears I do actually live in a place where Irish heritage is more prevalent.  Then I saw this map:

First and foremost, beware the Ides of March.

Ever wanted to see what Kurt Vonnegut looked like in high school?  Here you go!

Now the important stuff….how to pick the best seat at a restaurant or dinner party.  Read this so things like this won’t happen.

Now more unimportant stuff….how to make a cat avatar.

Now that we know how to make cats, why not make the cast of Game of Thrones?

I’m happy that’s coming back soon.

I should have clarified in post earlier today, that I was only wishing everyone a happy American Pi Day….or any others who use month/date/year convention.

For those of you using date/month, we’ll see you back here on April 31st.

For those of you preferring fractions, we’ll see you on July 22nd.

For those of you who try to make things universal by writing things like 14MAR13, y’all just screwed yourselves out of a holiday.  You’re not invited to my mole day party either.

So basically you can justify celebrating 3 different types of pi days.  I think that’s excellent.  I like pi.

It occurred to me this morning that in two years, pi day is going to be REALLY cool.

I’m falling behind in mentioning correct answers, so today I’m giving both a problem and an answer….two in fact.  Pick which one you thought of first.

Apparently the answer’s been a little controversial.

Last week reader panjoomby pointed me to an interesting study that correlated a countries sugar consumption to their rates of major depression.  Apparently that gives a correlation of .948.

Any time there’s a correlation that high, I’m going to get a look on my face that’s an interesting cross between curious and suspicious and that causes me to get wrinkles between my eyebrows.  I decided to take a look around for the full study, and found a copy here.  Basically the authors took data from the Food and Agricultural Organization  and correlated them with the results from a 1996 paper by Weissman et al published in JAMA called Cross-national epidemiology of major depression and bipolar disorder.

I couldn’t find a full free version of the mental health study, but I did find this update by the original author where she described what the study did (they surveyed people in the various countries for symptoms matching those for major depression, DSM III version)

A few things struck me about this study and it’s near-perfect correlation (shown below):

1. Only six countries were used for the correlation.  The original study on depression, they studied 10 countries:  Canada, U.S., Puerto Rico, France, Italy, West Germany (it was 1991), Lebanon, Taiwan, Korea, and New Zealand.   They clarified that Taiwan and Puerto Rico had no sugar consumption data.  Ultimately, their line consisted of Korea, France, Germany, US, Canada and New Zealand.  West Germany and Lebanon were not mentioned.  West Germany I presume something about it not existing any more, but Lebanon concerned me, as it was suggested it had very high rates of depression.  When I pulled my own data from the FAO, it looked like Lebanon’s sugar consumption was similar to Canada’s.  That would have change things a bit.
2. The country anchoring the bottom of the line is dramatically culturally different from the other 5 countries.  When I got my degree, I actually had to take an entire class on culturally sensitive counseling.  In it, we were reminded how many mental health standards were written either by North Americans or Europeans and how they really didn’t fit some cultures very well.  Asian cultures are notorious for under reporting symptoms, and for giving different names to things to avoid stigma.  This was admitted by the authors to be a weakness, but looking at the chart makes you realize this correlation would not be nearly as good if Korea wasn’t in the mix.
3. The only source of sugar they counted was sugar.  The FAO reports honey consumption.  And lots of fruits and date consumption.  I get why you wouldn’t throw fruit in there, but it seems to me that there are a few other sweeteners that might change the numbers.    Any hypothesis that posits that processed cane sugar can cause dramatic mental health issues should probably ponder what (if any) effect a different type of sugar could have, and if adding it in changed anything.  I mean, they mentioned dates in their first paragraph for heaven’s sake.
4. Every country on this list has to have a certain level of infrastructure to consume sugar and to be survey for depression.  Sugar tends to be more abundant in countries that have more food.  Countries that have more food tend to be better for researchers to set up shop in.  Countries without either are not included.  There’s some suggestion that quite a few poor countries might have really high depression rates thanks to malnutrition and otherwise terrible conditions.  That would definitely skew the line, and raise more questions about poverty rates in the originally studied countries.

As someone who still envisions the words “DON’T PANIC” in large friendly letters every time I get myself in a dicey situation, I thought I’d throw a few of his more memorable quotes out there for you, complete with when I tend to use them in my every day life:

Quote I say (at least in my head) every time I have flown, ever:
“It can hardly be a coincidence that no language on earth has ever produced the expression “As pretty as an airport.”

Quote I ponder when watching people on public transportation:
“There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable.There is another theory which states that this has already happened.”

Quote I think of when I’m lying on the couch and realize I’m thirsty but my water is in the dining room:
“Space is big. You just won’t believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it’s a long way down the road to the drug store, but that’s just peanuts to space.”

Quote I think of most often when I’m tripping over something or falling down stairs:
“There is an art, it says, or rather, a knack to flying. The knack lies in learning how to throw yourself at the ground and miss. … Clearly, it is this second part, the missing, which presents the difficulties.”

Quote I feel best describes my adolescence:
“A learning experience is one of those things that say, “You know that thing you just did? Don’t do that.”
