Perhaps most startling, children between the ages of 15 and 19 are 82 times more likely to die from gun homicide in the United States than in peer countries.

America has 4.4 percent of the world’s population, but almost half of the civilian-owned guns around the world. Research shows that the more guns in a country, the more gun deaths. Conversely, states with fewer guns have fewer gun deaths.

In cardiovascular terms, the drop in heart rate from 1000 steps/day to 2000 steps/day is significant: a full 3 bpm decrease. And as step count increases, resting heart rate steadily drops—until you reach about 5000 steps per day. After that—6000, 7000, even up to 10,000 steps—the curve flattens.

It’s science’s dirtiest secret: The “scientific method” of testing hypotheses by statistical analysis stands on a flimsy foundation. Statistical tests are supposed to guide scientists in judging whether an experimental result reflects some real effect or is merely a random fluke, but the standard methods mix mutually inconsistent philosophies and offer no meaningful basis for making such decisions. Even when performed correctly, statistical tests are widely misunderstood and frequently misinterpreted. As a result, countless conclusions in the scientific literature are erroneous, and tests of medical dangers or treatments are often contradictory and confusing.

You may have noticed another characteristic of contrarian climate research – there is no cohesive, consistent alternative theory to human-caused global warming. Some blame global warming on the sun, others on orbital cycles of other planets, others on ocean cycles, and so on. There is a 97% expert consensus on a cohesive theory that’s overwhelmingly supported by the scientific evidence, but the 2–3% of papers that reject that consensus are all over the map, even contradicting each other. The one thing they seem to have in common is methodological flaws like cherry picking, curve fitting, ignoring inconvenient data, and disregarding known physics.

Interestingly, both groups are using the same data, and both groups claim that the other is misrepresenting the data for their own purposes. As I will demonstrate, however, it is the anti-vaccers which are ignoring the rules of statistical analysis and manipulating the data to tell an inaccurate story.

To run a test that asks an important question, that uses a large enough sample size to come to a reliable conclusion, and that can do so amidst a minefield of different ways to be lead astray, takes a lot of resources.

You have to design the test, implement the technology, and come up with the various options. If you’re running a lean organization, there are few cases where this is worth the effort.

Why create a half-assed “A” and a half-assed “B,” when you could just make a full-assed “A?”

In this article we'll explore a neat way of visualizing your MP3 music collection. The end result will be a hexagonal map of all your songs, with similar sounding tracks located next to each other. The color of different regions corresponds to different genres of music (e.g. classical, hip hop, hard rock). As an example, here's a map of three albums from my music collection: Paganini's Violin Caprices, Eminem's The Eminem Show, and Coldplay's X&Y.
