Unlearn Something Wrong Today

Glass is not a high-viscosity liquid at room temperature: it is an amorphous solid, although it does have some chemical properties normally associated with liquids. Panes of stained glass windows often have thicker glass at the bottom than at the top, and this has been cited as an example of the slow flow of glass over centuries. However, this unevenness is due to the window manufacturing processes used in earlier eras, which produced glass panes that were unevenly thick at the time of their installation. It is common to find old windows which are thicker at the sides or the top.[114][115]

Wikipedia has a pretty good list of Common Misconceptions, with references explaining why they aren’t true, and what the real story is.  Unlearning a wrong fact is one of the hardest things to do as a human being, so do yourself a favor and unlearn something wrong today.

Fast food statistical lies

Rafe over at rc3.org provides a very important bit of fact checking to the fast food infographic that is circulating.  I thought 3800 seemed really high, but I didn’t bother with digging deeper.  He did.  I’m coopting his post in it’s entirety (it’s short) for those who aren’t reading his blog.

I’ve seen a number of links to the Everything You Need to Know About Fast Food infographic, which is chock full of interesting statistics, not all of which I’m entirely sure are accurate. It lists the average caloric intake for Americans as 3,760 calories, but I am pretty sure that is impossible.

This statistic comes from the UN Food and Agriculture Organization, but unfortunately the link is dead. Other sources report that the average caloric consumption for men in the US is around 2,618 calories for men and 1,877 calories for women — significantly less. A little back of the envelope math shows that the number cited in the infographic is impossible. The average height of men in the US is 5′ 9.5″ and the average weight is 191 pounds. The resting metabolic rate for 25 year old men of average height and weight is about 1900 calories. If you eat only 100 more calories a day than you expend, you’ll gain 10 pounds per year.

I’ve seen this number being repeated a lot, and I wanted to point out that there’s absolutely no way it’s correct. I haven’t seen the original source data, so maybe it’s a valid statistic that’s being misused, but in the context people are using it, it’s wrong.
