Are marriage and science compatible for women?

Marriage has been shown to have an adverse impact on the careers of female scientists. Data from the National Science Foundation show Doctoral women scientists and engineers are far less likely than men to be married: 66% of women doctoral scientists and engineers are married, compared with 83% of men. Doctoral women are 2 times as likely as men never to have married or to be divorced.
Among those married, however, women are more likely to confront problems accommodating a two-career marriage--one reason being that they are twice as likely as men to have a spouse who works full-time. Add children to the mix, and the problem is compounded.

Americans fail the test on evolution

1/3 American adults do not believe in evolution, a far larger fraction than in most European countries, a new study revealed. Of the 34 countries surveyed, only Turkey had a smaller percentage of adults who believed in evolution.
Michigan State University's Jon D. Miller, who carried out the research, theorized that "Individuals who hold a strong belief in a personal God—and who pray frequently—were significantly less likely to view evolution as probably or definitely true than adults with less conservative religious views."

why do we still use roman numerals? or
Is there a roman numeral 0?


How to lose weight ?

Easy, try eating off smaller plates and bowls.
Study shows that using smaller bowls and spoons may curb the amount of food eaten.
There was a earlier study found that teenagers poured 77% less juice into tall narrow glasses than they did into short wide glasses. In a recent study, participants were randomly given a 17 ounce or 34 ounce bowl along with a 2 ounce or 3 ounce ice cream scoop and allowed to serve themselves ice cream. Altogether, those with large bowls and large serving spoons served themselves — and ate —nearly 57% more ice cream than those with smaller bowls and spoons.

Harry Potter is more familiar to us than British premier

More Americans know who Harry Potter is than who Prime Minister Tony Blair is, according to a recent pop culture survey. Of the 1,213 Americans questioned by the poll, 57% knew of J.K. Rowling's boy wizard Potter. That compares with the 49.5% who could name Blair as the British prime minister when asked.

Doubt those numbers? Try Paris Hilton.

Thank Jemima Jemima the Secretary for this number.

Should I have my surgery done in the morning or afternoon ?

Earlier surgery, better recovery.
Analysis of more that 90,000 surgeries performed at Duke University Medical Center from May 2000 to August 2004 showed anesthesia-related problems such as postoperative nausea and inadequate pain relief occurred more than 4 times as often at 4 pm - affecting about 1 in 25 patients - as at 9 am. Staff fatigue, shift changes, and the same afternoon slump in caregivers' body rhythms that affects other people could be among the many causes.
The same thing can be said for most of things we do. Don't you say ?

Economical numbers

"There are 10^11 stars in the galaxy. That used to be a huge number. But it's only a hundred billion. It's less than the national deficit! We used to call them astronomical numbers. Now we should call them economical numbers".
-Richard Feynman, physicist, Nobel laureate (1918-1988).


Six degree of separation

Six degrees of separation is the hypothesis that anyone on Earth can be connected to any other person on the planet through a chain of acquaintances with no more than 5 intermediaries.
The latest proof of this hypothesis - in 2001 Duncan Watts, a professor at Columbia University, used an e-mail message as the "package" that needed to be delivered, and after reviewing the data collected by 48,000 senders and 19 targets (in 157 countries), Watts found that the average number of intermediaries was, 6.

Sex Differences in the Brain

Chart above is a summary of recent a study on psychological gender differences.
In comparing differences between the sexes, researchers use a statistical measure called d. This indicates how far apart the averages of two groups (in this case men and women) are, taking into account the range of values that contribute to each average. For example, the value of d for adult height is around 2. There is no arguing that in any given population men, on average, are taller than women. For behavioural and psychological phenomena, a value of d greater than 0.8 is considered large, of 0.5, moderate, and of 0.2, small. Any d less than 0.2 is a negligible difference.
Of the 124 cognitive tasks studied, 30% had a value of d close to zero and in a further 48% of cases, d was small. In other words, only 22% of reported behavioural differences between the sexes are worth raising an eyebrow over.
In summary, men and women think differently, but not that differently.
