Math Wonder

Danica McKellar is counting on girls to love numbers.

When a classmate in her freshman math class at UCLA tapped Danica McKellar on the shoulder and asked, "Aren't you the girl who …" she expected him to quiz her about her role as Winnie Cooper on the iconic television show The Wonder Years. Instead he continued, "… got the best score on the exam?" For the first time, McKellar felt recognized as something other than a child actress.Even though the show's producers needed to hire an advanced calculus tutor to keep up with the child star's aptitude, she had never considered becoming a mathematician. Social conditioning, says 32-year-old McKellar, made her believe girls didn't have a place in the math world. "Who did I think math was for, if it wasn't for me?"McKellar headed to college intending to study writing and directing, but ended up putting her numerical skills to use instead, earning a math degree summa cum laude and co-authoring a research paper that solved a statistical mechanics problem involving magnetism in two dimensions-a solution now known as the Chayes-McKellar-Winn theorem.\n\n\n
Who did I think math was for, if it wasn't for me?
From her math classes, McKellar learned that solving probabilities wasn't going to solve the biggest math problem in the United States: "Girls fear math," she says. Although girls and boys in fourth and eighth grades have similar math and science proficiency scores, a national survey recently found that girls are less likely than boys to agree with the statements "I like mathematics" and "I like science." Teachers often unknowingly foster this preference, which, McKellar claims, isn't helped by the feeling among young girls that they need to act ditzy in order to get boys to like them. The negative attitudes girls hold for math translate into career choices later on in life: Four times as many men as women hold full-time university faculty positions in mathematics, science, and engineering. And as McKellar sat in a sea of male classmates in her advanced classes she realized she was living the direct repercussions of these early gender inequalities.McKellar plans to change these statistics by putting some of her other skills to work. "Math doesn't have good PR. I'm going to do my best to do great PR for math," she says. As a spokesman for the National Council of Teachers of Mathematics, she testified to a Congressional subcommittee in 2000 about the country's need to better prepare math teachers and draw more young girls toward math, especially at the age when they tend to start avoiding the subject. "Not only is middle school a time in life when girls are dealing with so much emotionally, it's also when math gets harder."

To help girls struggling with the complexity that comes with seventh-grade math, McKellar has penned Math Doesn't Suck: How to Survive Middle School Math Without Losing Your Mind or Breaking a Nail, which hits shelves this August. The book hones in on middle school's trickiest points-––like fractions, ratios, and percentages-and presents them in a style that's appropriate for the cool kids' lunch table. Figure out your "type" in boys and you'll understand greatest common factors. All of those iced lattes celebrities drink make multiplying fractions tasty. Plus, savvy shopping requires killer decimal skills.As McKellar fields math questions from kids on her personal website she sees how the hard work and persistence required by math can empower girls. The subject has a reputation for being tough, but coming up with the right numbers can give girls an important boost of courage.

When former Pittsburgh Steelers' center Mike Webster committed suicide in 2002, his death began to raise awareness of the brain damage experienced by NFL football players. A 2017 study found that 99% of deceased NFL players had a degenerative brain disease known as CTE (chronic traumatic encephalopathy). Only one out of 111 former football players had no sign of CTE. It turns out, some of the risks of traumatic brain injury experienced by heavily padded adults playing at a professional level also exist for kids with developing brains playing at a recreational level. The dangers might not be as intense as what the adults go through, but it can have some major life-long consequences.

A new PSA put out by the Concussion Legacy Foundation raises awareness of the dangers of tackle football on developing brains, comparing it to smoking. "Tackle football is like smoking. The younger I start, the longer I am exposed to danger. You wouldn't let me smoke. When should I start tackling?" a child's voice can be heard saying in the PSA as a mother lights up a cigarette for her young son.

On Tuesday morning, President Trump tweeted about some favorable economic numbers, claiming that annual household income is up, unemployment is low, and housing prices are high.

Now, just imagine how much better those numbers would be if the country wasn't mired in an economy-killing trade war with China, bleeding out trillion-dollar-a-year debts, and didn't suffer from chaotic leadership in the Oval Office?

At the end of tweet, came an odd sentence, "Impeach the Pres."

October is domestic violence awareness month and when most people think of domestic violence, they imagine mostly female victims. However, abuse of men happens as well – in both heterosexual and homosexual relationships. But some are taking it upon themselves to change all that.

At this point most reasonable people agree that climate change is a serious problem. And while a lot of good people are working on solutions, and we're all chipping in by using fewer plastic bags, it's also helpful to understand where the leading causes of the issue stem from. The list of 20 leading emitters of carbon dioxide by The Guardian newspaper does just that.

Before the release of "The Joker" there was a glut of stories in the media about the film's potential to incite violence.

The FBI issued a warning, saying the film may inspire violence from a group known as the Clowncels, a subgroup of the involuntarily celibate or Incel community.

Incels an online subculture who believe they are unable to attract a sexual partner. The American nonprofit Southern Poverty Law Center describes them as "part of the online male supremacist ecosystem" that is included in its list of hate groups.
