Yes, You Can Drink Cold Water

My yoga teacher told us a few weeks back that we should refrain from drinking cold water, either with meals or at any other time. This led to a pointed rebuke from another long-time student who had an extensive nutritional background, and the merry debate went on until the instructor ended with, “Well, this was what they told me in a physiology class that I’m taking.”

I remembered this exchange reading last week in the NY Times about a study which showed people often cling to ideas which conflict with scientific consensus and common sense. Further, that those who often feel strongest are often the least knowledgeable. Although this seems counterintuitive , almost surreal, we have seen this in action. In fact, this conundrum seems to be one of the most pressing problems of our time, one which, despite the ready availability of good information, persistently leads to the opposite. Case in point: reactions to the Mueller report. Case in point: the recent outbreak of measles, which ought to have been eradicated in the U.S. Case in point: see my post about eating cheese.

Why do easily validatable yet unsubstantiated ideas get so easily disseminated and supported? Perhaps it is a function of our response to the Information Superhighway which gives us 1) too much information 2) sometimes delivered by the unscrupulous which leaves us to be 3) overly reliant on people we (think we) can trust. Because 4) you can drink cold water.

Trigonometry: Secant-ing out New Life in Ancient Civilizations

It’s irresistible. The siren song of Wikipedia calls to me. All I was trying to do was find out which Greek invented trigonometry. Was it Pythagoras and his bean-renouncing cult or someone else? And I come across this enticing little tidbit, a curious little reference which, to a history buff is like the smell of fresh cookies…

Based on one interpretation of the Plimpton 322 cuneiform tablet (c. 1900 BC), some have even asserted that the ancient Babylonians had a table of secants.[8] There is, however, much debate as to whether it is a table of Pythagorean triples, a solution of quadratic equations, or a trigonometric table.

Much debate? Some have asserted? This sounds like historical mystery to me. I was instantly overjoyed at the thought of poking around to see if anyone denounced anyone else in the public square or started fistfights or wrote long letters to the editor of scientific journals about how their enemies were cretins who didn’t know a hypotenuse from a hippopotamus. And I wasn’t disappointed.

Don’t Be Afeared, it’s Just Math

First, a few definitions. Even if you’ve never taken trigonometry or if the very word causes you to put a blanket over your head, don’t worry. Imagine that it’s a warm sunny day in Greece (or Babylonia or Sumeria or Egypt) and you notice that the pillar of the nearby temple, next to where you are sunning yourself, throws a shadow. Since you like to measure things, you get out your handy measuring stick and you measure the length of the shadow. You know the length of the pillar. You start doing calculations.

Friday Fictioneers: The Ruins*

Over time, the fortress crumbled and the crows took over, fighting battles of their own over the parapets. Ordinary people, no longer as valiant or as bloodthirsty as the ones who had thundered across the hills, built houses, cheery green and yellow boxes everywhere. The railroad men drove their tracks boldly right below, and people climbed on and off the train as if nothing had ever happened.

But the stationmaster always shook his head when asked about tours up the hill.

“Up there? Nar. I never goes up there.”

As the 4:17 started to chug its way, his feet felt the vibrations. Felt them as always, continue long after the cars had blurred across the fields, continue underneath, as if something there was just waiting.
