Why Smart People Are Stupid

In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?

Turns out that people, and especially smart people, are not nearly as rational as they believe.

LIVE COVERAGE FROM NASA OF VENUS TRANSIT

A very rare occurrence. From wikipedia.com

transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and Earth, becoming visible against (and hence obscuring a small portion of) the solar disk. During a transit, Venus can be seen from Earth as a small black disk moving across the face of the Sun.

The Science of ‘Gaydar’

Some light reading to take your mind off of Europe. This research shows your guess at someone’s sexual orientation is probably 60% correct, even if you’ve seen their face for less than a second.

We conducted experiments in which participants viewed facial photographs of men and women and then categorized each face as gay or straight. The photographs were seen very briefly, for 50 milliseconds, which was long enough for participants to know they’d seen a face, but probably not long enough to feel they knew much more. In addition, the photos were mostly devoid of cultural cues: hairstyles were digitally removed, and no faces had makeup, piercings, eyeglasses or tattoos.

Even when viewing such bare faces so briefly, participants demonstrated an ability to identify sexual orientation: overall, gaydar judgments were about 60 percent accurate.

ATTENTION: Taking Calcium Pills Increases Chance of Heart Attack by 86%!

The study of approximately 24,000 people between the ages of 35 and 64 found participants who took regular calcium supplements were 86% more likely to have a heart attack than those who didn’t take supplements. Those who took only calcium supplements were twice as likely to suffer a heart attack as those who didn’t take any vitamin supplements. Calcium supplements have been linked to kidney stones and bloating in other studies, according to the National Institutes of Health.

“Calcium supplements have been widely embraced by doctors and the public, on the grounds that they are a natural and therefore safe way of preventing osteoporatic fractures,” the authors write. “We should return to seeing calcium as an important component of a balanced diet.”

The study, primarily undertaken to determine if calcium supplements modify cardiovascular risk factors, found no direct link between the supplements and heart attacks, nor did they identify brands of supplements. Participants answered questions about their use of supplements and their diet during an 11-year study of their health.

The study did not look at what caused the heart attacks, but the authors write: “Supplements cause calcium levels to soar above the normal range, and it is this flooding effect which might ultimately be harmful.”

“Doctors who work with the elderly and people who are postmenopausal routinely tell them to take a calcium supplement,” says Linda Russell, a rheumatologist and osteoporosis specialist at Hospital for Special Surgery in New York. “It’s really time to re-examine that philosophy. Other studies about calcium have been suggesting this in recent years, but maybe this study really should get doctors to rethink this approach.”
