> While looking at number of influences on the presidential vote outcome, we found that in a year of massive divides, one particular economic split stands out. With few exceptions Clinton won every large-sized county economy in the country.

Trump's $7MM deal with Indiana and Carrier has a -102.9% ROI:

Someone on reddit did the math on the Carrier deal. It’s a bad deal.

More importantly, it’s the opposite of what Trump ran on. Tough guy Trump talked about taxing companies that moved jobs to Mexico. Here he is giving them money while they move a net 200 jobs to Mexico.

Congressional Research Service Report On Tax Cuts For Wealthy Suppressed By GOP

The pressure applied to the research service comes amid a broader Republican effort to raise questions about research and statistics that were once trusted as nonpartisan and apolitical

Math has a liberal bias.

The statistical sample set of “All my friends on Facebook” has a margin of error of around +/-50%

Researchers examined how the Mundurucu think about lines, points and angles, comparing the results with equivalent tests on French and US schoolchildren.

The Mundurucu showed comparable understanding, and even outperformed the students on tasks that asked about forms on spherical surfaces.

…

The ideas are profoundly ingrained in formal education, but what remains a matter of debate is whether the capacity, or intuition, for geometry is present in all peoples regardless of their language or level of education.

…

"Mundurucu is a language with only approximative numbers," Dr Pica told BBC News.

"You don’t have a lot of geometrical terms like square or triangle or anything like that, and no way of saying two lines are parallel… it looks like the language does not have this concept."

…

The Mundurucu people’s responses to the questions were roughly as accurate as those of the French and US respondents; they seemed to have an intuition about lines and geometric shapes without formal education or even the relevant words.

Do you not need a concept of math to have mathematical concepts? I’m curious if the test might be performed in a similar way against other cultures with mathematical terms.

In director George Lucas’ updated cut of the movie Star Wars, character Han Solo rapidly shoots a loan-shark alien twice at a bar. Physics blogger Rhett Allain crunches the numbers to see if the feat is really possible.

Over-thinking at its geeky best.

While browsing today, I found this page which thoroughly describes the use of the regular expression /^1?$|^(11+?)\1+$/ in Perl to check if a number is prime or not!!!

To be frank, I was skeptical. The regular expression looks like magic! And I wanted to understand it better. I rewrote it in Ruby using irb and I tested it:

Amazing. I’ve seen some really hairy regex code but that takes the cake.
