• Good afternoon, Quad-Cities. Here is your National Weather Service forecast.

This afternoon will be sunny with a high near 26 degrees. North winds will be 10-15 mph with gusts as high as 20 mph.

Tonight will be mostly clear with a low around 6 degrees. Wind-chill values could be as low as -5 degrees. Northwest winds will be around 5 mph.

Wednesday will be sunny with a high near 31 degrees. Wind chill values could be as low as -5 degrees. Northwest winds will be around 5 mph.

Wednesday night will be mostly clear with a low around 16 degrees. West winds will be around 5 mph becoming calm.

For those wondering about yesterday's snowstorm, 6.9 inches of snow was officially recorded at the Davenport Airport while 4.8 inches of snow was recorded at the Quad-City International Airport in Moline. About an inch-an-a-half of new snow fell today in the Q-C.

• Heading east? Not a good idea. Places like Washington, D.C., New York City and Boston have been hit with more than a foot of snow. Numerous eastern airports are closed which is causing flight delays across the country, including the Quad-Cities. Check our flight tracker for flight delays and cancellations.

The best (and worst) of spring break


• Many schools are on or going to be on spring break. Florida's gulf coast and Cancun remain the top spots for midwest college and high school students during spring break. Take a look back at some of the top images from spring breaks past. See more.

Lawmaker mocks abortion law with call for masturbation fines


Jessica Farrar

Our public servants at work: A Texas lawmaker is making a point about legislation that restricts women's access to health care and abortions by proposing to fine men $100 when they masturbate.

Alongside the penalty for wasting semen not resulting in a pregnancy, state Rep. Jessica Farrar's bill would require a "medically unnecessary digital rectal exam" before any man undergoes a vasectomy or can be prescribed Viagra.

The 11th term Democrat tells the Houston Chronicle that her bill mimics how a woman seeking an abortion is forced by Texas law to undergo a transvaginal ultrasound, which "has nothing to do with her health care."

She says while some people think it's funny, her bill highlights the obstacles women face "that were placed there by legislatures making it very difficult for them to access health care."

3.14 essential reads about π for Pi Day


And by now you have probably heard, today is Pi Day.

On March 14, or 3/14, mathematicians and other obscure-holiday aficionados celebrate Pi Day, honoring π, the Greek symbol representing an irrational number that begins with 3.14. Pi, as schoolteachers everywhere repeat, represents the ratio of a circle’s circumference to its diameter.

What is Pi Day, and what, really, do we know about π anyway? Here are three-and-bit-more articles to round out your Pi Day festivities.

A silly holiday

First off, a reflection on this “holiday” construct. Pi itself is very important, writes mathematics professor Daniel Ullman of George Washington University, but celebrating it is absurd:

"The Gregorian calendar, the decimal system, the Greek alphabet, and pies are relatively modern, human-made inventions, chosen arbitrarily among many equivalent choices. Of course a mood-boosting piece of lemon meringue could be just what many math lovers need in the middle of March at the end of a long winter. But there’s an element of absurdity to celebrating π by noting its connections with these ephemera, which have themselves no connection to π at all, just as absurd as it would be to celebrate Earth Day by eating foods that start with the letter “E.”

And yet, here we are, looking at the calendar and getting goofily giddy about the sequence of numbers it shows us.

There’s never enough

In fact, as Jon Borwein of the University of Newcastle and David H. Bailey of the University of California, Davis, document, π is having a sustained cultural moment, popping up in literature, film and song:

"Sometimes the attention given to pi is annoying. On 14 August 2012, the U.S. Census Office announced the population of the country had passed exactly 314,159,265. Such precision was, of course, completely unwarranted. But sometimes the attention is breathtakingly pleasurable."

Come to think of it, pi can indeed be a source of great pleasure. Apple’s always comforting, and cherry packs a tart pop. Chocolate cream, though, might just be where it’s at.

Strange connections

Of course π appears in all kinds of places that relate to circles. But it crops up in other places, too – often where circles are hiding in plain sight. Lorenzo Sadun, a professor of mathematics at the University of Texas at Austin, explores surprising appearances:

"Pi also crops up in probability. The function f(x)=e-x², where e=2.71828… is Euler’s number, describes the most common probability distribution seen in the real world, governing everything from SAT scores to locations of darts thrown at a target. The area under this curve is exactly the square root of π."

It’s enough to make your head spin.

Historical pi

If you want to engage with π more directly, follow the lead of Georgia State University mathematician Xiaojing Ye, whose guide starts thousands of years ago:

"The earliest written approximations of pi are 3.125 in Babylon (1900-1600 B.C.) and 3.1605 in ancient Egypt (1650 B.C.). Both approximations start with 3.1 – pretty close to the actual value, but still relatively far off."

An irrational bonus

And because π is irrational, we’ll irrationally give you even one more, from education professor Gareth Ffowc Roberts at Bangor University in Wales, who highlights the very humble beginnings of the symbol π:

"After attending a charity school, William Jones of the parish of Llanfihangel Tre’r Beirdd landed a job as a merchant’s accountant and then as a maths teacher on a warship, before publishing A New Compendium of the Whole Art of Navigation, his first book in 1702 on the mathematics of navigation. On his return to Britain he began to teach maths in London, possibly starting by holding classes in coffee shops for a small fee.

"Shortly afterwards he published “Synopsis palmariorum matheseos,” a summary of the current state of the art developments in mathematics which reflected his own particular interests. In it is the first recorded use of the symbol π as the number that gives the ratio of a circle’s circumference to its diameter."

What made him realize that this ratio needed a symbol to represent a numeric value? And why did he choose π? It’s all Greek to us.
