e=mc2: 103 years later, Einstein’s proven right

Posted by tenyardfede on November 22, 2008

103 years later, Einstein's proven right AFP/File – People walk past a giant sculpture featuring Albert Einstein’s formula “E=mc2″ in front …

PARIS (AFP) – It’s taken more than a century, but Einstein’s celebrated formula e=mc2 has finally been corroborated, thanks to a heroic computational effort by French, German and Hungarian physicists.

A brainpower consortium led by Laurent Lellouch of France’s Centre for Theoretical Physics, using some of the world’s mightiest supercomputers, have set down the calculations for estimating the mass of protons and neutrons, the particles at the nucleus of atoms.

According to the conventional model of particle physics, protons and neutrons comprise smaller particles known as quarks, which in turn are bound by gluons.

The odd thing is this: the mass of gluons is zero and the mass of quarks is only five percent. Where, therefore, is the missing 95 percent?

The answer, according to the study published in the US journal Science on Thursday, comes from the energy from the movements and interactions of quarks and gluons.

In other words, energy and mass are equivalent, as Einstein proposed in his Special Theory of Relativity in 1905.

The e=mc2 formula shows that mass can be converted into energy, and energy can be converted into mass.

By showing how much energy would be released if a certain amount of mass were to be converted into energy, the equation has been used many times, most famously as the inspirational basis for building atomic weapons.

But resolving e=mc2 at the scale of sub-atomic particles — in equations called quantum chromodynamics — has been fiendishly difficult.

“Until now, this has been a hypothesis,” France’s National Centre for Scientific Research (CNRS) said proudly in a press release.

“It has now been corroborated for the first time.”

For those keen to know more: the computations involve “envisioning space and time as part of a four-dimensional crystal lattice, with discrete points spaced along columns and rows.”

College Applicants, Beware: Your Facebook Page Is Showing

Posted by tenyardfede on November 7, 2008

High-school seniors already fretting about grades and test scores now have another worry: Will their Facebook or MySpace pages count against them in college admissions?

A new survey of 500 top colleges found that 10% of admissions officers acknowledged looking at social-networking sites to evaluate applicants. Of those colleges making use of the online information, 38% said that what they saw “negatively affected” their views of the applicant. Only a quarter of the schools checking the sites said their views were improved, according to the survey by education company Kaplan, a unit of Washington Post Co.

Some admissions officers said they had rejected students because of material on the sites. Jeff Olson, who heads research for Kaplan’s test-preparation division, says one university did so after the student gushed about the school while visiting the campus, then trashed it online. Kaplan promised anonymity to the colleges, of which 320 responded. The company surveyed schools with the most selective admissions.

[College Applicants, Beware Facebook]

Admissions officers have acknowledged looking at social-networking sites like Facebook to evaluate applicants.

The vast majority of the colleges surveyed had no policy about when it was appropriate for school officials to look at prospective students’ social-networking sites. “We’re in the early stage of a new technology,” Mr. Olson says. “It’s the Wild, Wild West. There are no clear boundaries or limits.”

The lack of rules is already provoking debate among admissions officers. Some maintain that applicants’ online data are public information that schools should vet to help protect the integrity of the institutions. Others say they are uncomfortable flipping through teenage Facebook pages.

Colleges’ recent interest in social-networking sites is leading many aspiring students to take a hard look at their online habits and in some cases to remove or change postings. With a high-school graduating class nationwide of 3.3 million students, colleges are expected to be sifting through a record number of applications this year.

Nicholas Santangelo, a senior at Seton Hall Prep, a private school in West Orange, N.J., says he expects colleges might look at his Facebook site but hopes admissions officers realize the postings reflect only a partial view of any student. “There are some things I might think about getting rid of,” says Nicholas, 17, who is considering such competitive schools as Amherst College and Wesleyan University.

Sites like Facebook and MySpace let users set up online profiles — including pictures, videos and other personal information — then solicit others to join their network of online “friends.” Users can exchange messages, often publicly, and sometimes offer detailed descriptions of their activities, dreams and fears.

The sites have inspired many a national conversation over privacy and exhibitionism. Some job applicants have already discovered the hard way that employers often examine the sites to weed out candidates. Representatives of the sites say users can establish online privacy settings that let their pages be viewed only by invited “friends.” MySpace is part of News Corp., which owns The Wall Street Journal. Facebook is closely held.

But Kaplan and many high-school guidance counselors say students often don’t restrict public access on social-networking sites and, in any case, damaging information can find a way to leak out. David Hawkins, director of public policy and research for the National Association for College Admission Counseling, a professional organization, says schools don’t have time to scour the Internet systematically to check out thousands of applicants. But he says admissions officers at times receive anonymous tips, which may be from rival applicants, about embarrassing Facebook or MySpace material, such as a picture of a student drunk at an underage party.

In another recent study, Nora Ganim Barnes, director of the Center for Marketing Research at the University of Massachusetts at Dartmouth, found that 21% of colleges used social-networking sites for recruiting prospects and gathering information about applicants. It’s especially common when universities are awarding scholarships because it isn’t hard to go online for a handful of finalists. “No one wants to be on the front page of the newspaper for giving a scholarship to a murderer,” she says. “Everybody is trying to protect their brands.”

Thomas Griffin, director of undergraduate admissions at North Carolina State University in Raleigh, says the school will do an Internet search, including Facebook and other sites, if an application raises “red flags,” such as a suspension from school. Mr. Griffin says several applicants a year have been rejected in part because of information on social-networking sites. In a recent case, the university researched a student who disclosed on his application that he had been disciplined for fighting. The school found a Facebook page with a picture of the applicant holding a gun. “We have to use this information to make the best decision for the university,” Mr. Griffin says.

Janet Lavin Rapelye, dean of admission at Princeton University, says the school hasn’t rejected any applicant because of information posted on the Internet. Princeton doesn’t have time to look at all applicants’ online information, but if an offensive Facebook post came to the college’s attention, the school would examine it, Ms. Rapelye says. “All of us would consider anything that would cause us to doubt a student’s character,” she says.

Greg Roberts, senior associate dean of admission at the University of Virginia, says his staff is free to check out anonymous tips about social-networking sites or make use of the information if the admissions committee is evaluating a “tight” decision.

Sandra Starke, vice provost for enrollment management at the State University of New York at Binghamton, says she instructs her staff to ignore Facebook and other sites because she considers postings to be casual conversations, the online equivalent of street-corner banter. “At this age, the students are still experimenting,” she says. “It’s a time for them to learn. It’s important for them to grow. We need to be careful how we might use Facebook.”

Marc Prablek, a senior at Ladue Horton Watkins High School in suburban St. Louis, considers Facebook information “out in the public” and fair game for colleges. The 17-year-old, with some 550 “friends,” says, “I don’t have anything bad on Facebook,” but he may tweak his profile to be “more sophisticated.”

Marc, who plans to apply early to Stanford University, says he won’t mention that he loves to read X-Men comic books. His Facebook literary picks currently include “Crime and Punishment” and “Pride and Prejudice.”

High-school guidance counselors advise applicants, even if they restrict public access on their sites, to refrain from including anything that could hurt them in college admissions. They especially caution against foul or offensive language, nudity, or photos of drinking and drug use.

“Students need to be accountable for their actions,” says Scott Anderson, director of college guidance at St. George’s Independent School, a private school near Memphis, Tenn. When writing on Facebook or MySpace, he says, they should be thinking, “Is this something you want your grandmother to see?”

Underwear-clad Delta girls streak up a storm at high school football game

Posted by tenyardfede on November 7, 2008

A group of high school girls in Delta, B.C., ran across a football field almost naked during half time of a game last week and sprayed silly string on members of the opposing team.

Twelve female high school students sporting only their underwear and duct tape around their breasts ran across a football field during their school team’s home game last week in Delta, B.C.

The principal of South Delta Secondary School said Wednesday he doesn’t want to see a repeat of the prank and has issued warnings to the Grade 12 students, most of them cheerleaders of the home team.

“We don’t take it lightly. This is a school. [In] schools, we hold higher ideals than we do in, say, the mall,” Ted Johnson told CBC News in an interview.

The streaking happened on Oct. 28 during a Delta Sun Devils game against the Lord Tweedsmuir Panthers of Lord Tweedsmuir Secondary School from Surrey.

Twelve female high school students sporting only their underwear and duct tape around their breasts ran across a football field during their school team’s home game last week in Delta, B.C.

The principal of South Delta Secondary School said Wednesday he doesn’t want to see a repeat of the prank and has issued warnings to the Grade 12 students, most of them cheerleaders of the home team.

“We don’t take it lightly. This is a school. [In] schools, we hold higher ideals than we do in, say, the mall,” Ted Johnson told CBC News in an interview.

The streaking happened on Oct. 28 during a Delta Sun Devils game against the Lord Tweedsmuir Panthers of Lord Tweedsmuir Secondary School from Surrey.

Video footage obtained by CBC News shows a dozen South Delta students wearing very little run across the field and spray silly string on the opposing team during half time.

Johnson said he warned students last month not to streak at this year’s final game of the season but was, obviously, ignored. Many parents and children left the game in disgust after the prank, he said.

“Our position is one that we don’t celebrate this. We don’t find it funny,” he said.

The girls, calling what they did a “harmless prank,” said streaking is a tradition at their school.

“It’s just kind of like a fun [graduation] prank for our year, and it’s been going on for a couple of years now,” said one of the girls, who wanted to be identified only as Rochelle. “It was pretty much out of fun.”

“They [school officials] just need to lighten up, really. It was a joke,” Michelle, another girl, said. “When our parents were in school, … there were way worse things, so this isn’t a big deal really.”

Johnson said he has told the girls involved that they will be suspended from school if they do anything else wrong.

They must also encourage younger students to end the streaking tradition, Johnson said.

Students’ stage strip for teachers

Posted by tenyardfede on November 3, 2008

School girls

Video images captured by pupils of the girls’ striptease

Teachers have refused to stop an annual striptease by pupils despite a video of an onstage lesbian love romp ending up on YouTube.

Film of the girls stripping off in front of teachers and pupils sparked outrage among education chiefs who now want it banned.

But officials at the school in Denmark are fighting to hold onto the annual event.

A spokesman said: ‘The girls’ teachers vote as the best get the best places on the tables in the canteen.’

Erik Olesen, head teacher at Silkeborg said everyone, including the school governors, had known about the contest and described it as ‘harmless fun’.

But news of the striptease got out when some of the girls this year stripped naked and began to touch each other’s breasts – then started rubbing baby oil over each other’s bodies.

Two girls put on a lesbian show to cheering classmates and teachers

The whole incident was filmed by four other students on their mobile phones who then posted it on the internet. It has since been removed from YouTube.

The 18-year-old girls were only stopped from going further by teachers.

Headmaster Olesen said: ‘I think they forgot what they were doing and where they were. But my concern now is not to punish anyone, but protect the girls who are now all over the internet.

‘As for the students who recorded the contest, they didn’t realize they had done anything illegal and I have had a long talk with them.’

But he added that he had no plans to scrap the striptease competition at the school. ‘I am sure nothing like this will happen again,’ he said.

‘And anyway, the girls who did this didn’t win the competition because their performance was over the top.’

sexy prof strips for students

Posted by tenyardfede on November 2, 2008

Furious parents have called for a saucy teacher to be sacked after she put on a saucy strip show for her 15-year old pupils.

The German minx was supposed to be supervising a start of term party.

But things got out of hand as the pretty teacher put on her own s-extracurricular activities for the teen pupils.

She seductively stripped down to her underwear – to the joy of her howling students.

And she only stopped her X-rated High School musical when another teacher forced her to cover up.

But one goggle-eyed pupil filmed the show on his mobile phone.

The teacher is seen peeling off her top to reveal her bra and then starts to undo the zip of her trousers before another lecturer covers her in a tablecloth.

“It is disgusting. What kind of teacher acts that way in front of her pupils. She should be in a lap dancing bar, not a school,” said one angry parent.

“The children were playing truth or dare and making bigger and bigger dares for each other and she decided to join in.

“When they dared her to do some pole dancing she just started taking off her clothes. She’s a pretty woman in her 20s and the children couldn’t believe their luck.

“The worst thing is that teachers weren’t even supposed to be taking part in the party – they were supposed to be supervising it,” they added.

But the school’s headmaster in Zalaegerszeg, western Hungary, has refused to sack the unnamed mistress despite pressure from parents and other teachers.

“I was forced to give the German teacher a warning, but I will not dismiss her because she is a valuable teacher for our institution,” said head Sandor Rozman.

He claimed she had shown no more flesh “than you would see on a beach.”
