Scientists Just Teleported an Object Into Space for the First Time

 

Scientists have successfully teleported an object from Earth to space for the first time, paving the way for more ambitious and innovative breakthroughs.

A group of investigators in China delivered a photon in the floor to an orbiting satellite over 300 miles over through a process called quantum entanglement, based into MIT Technology Review. It is the farthest distance analyzed up to now from teleportation experiments, the investigators said. Their work was published online on the open access website arXiv.

For about a month, the scientists beamed up millions of photons in their ground station in Tibet into the low-orbiting satellite. They were successful in over 900 cases.

“This work establishes the initial ground-to-satellite up-link for loyal and ultra-long-distance quantum teleportation, an important step toward global-scale quantum Web,” the group said in a statement, based on MIT Technology Review.

The MIT-owned magazine described quantum entanglement as a “strange phenomenon” that happens “when two quantum objects, like photons, form at exactly the exact same moment and point in space and thus share the same existence.” “In technical terms, they are described by exactly the exact same wave function,” it stated.

The most recent development comes nearly a year after physicists successfully ran the world’s first quantum teleportation out of a lab. Scientists at the time decided quantum teleportation, which is frequently portrayed as a futuristic tool in science-fiction movies, is actually possible.

Australian schoolgirl (Sofia) wins right to wear shorts instead of skirt to school

Australian schoolgirl (Sofia) wins right to wear shorts instead of skirt to school

Students at a private school in Sydney,

SYDNEY, Australia — Women at public schools throughout the state of Western Australia will be permitted to wear shorts and pants to class, no longer limited to just dresses, skirts or skorts.




Pupils and parents have long voiced complaints about the coverage, but the pushback has gained renewed momentum.

Following Krystina Myhre, of Perth, found that her 11-year-old, Sofia, couldn’t wear shorts to school, they wrote to the nation’s education minister, Sue Ellery, calling for a shift.

“My daughter and her friends have been very unhappy about it for a while,” stated Ms. Myhre, who’s also a representative of Girls’ Uniform Agenda, a group that campaigns for women to have the choice of wearing shorts and shorts. The rule restricted their movement, she said, which makes them worry about their own body and space.

The dress code made it hard to take part in athletic activities, Sofia said.




“I think it’s really unfair that my brothers are permitted to wear shorts, and throughout primary school I have not been permitted to except when I’ve game,” she wrote in her letter. “I actually love kicking the footy, netball and performing handstands in recess and lunch. It’s bothersome doing these things in a skirt.”

The change doesn’t apply to private colleges, but several private schools in Perth reported this week that they intended to follow suit. “We’re introducing trousers for women next year, but it is very much a choice,” said Robert Henderson, principal of John XXIII College, a Catholic private school. “It is definitely not throwing out the traditional uniform.” The decision came after consulting with workers, pupils and parents.

It’s unclear how many schools around Australia require women to wear skirts.

Up to now, about 70 percent of public high schools and all private high schools in Brisbane, Queensland, mandate wearing a skirt, ” said Amanda Mergler, a co-founder of this group, but a couple of private schools make it possible for exceptions in the winter. That percentage is probably similar in other nations, too.

This type of requisite, Dr. Mergler said, can perpetuate harmful gender stereotypes, leaving women to think that they ought to sit and look pretty, while boys might be perceived as active explorers. Dr. Mergler said she pulled her 6-year-old daughter from 1 school after a classmate told her she couldn’t use the girls’ toilet because she was wearing trousers. “They’re sitting back on the sidelines and watching boys run around and playing in shorts.”

1 research in 2012 discovered that when 10-year-old women wore sports uniforms over skirts, they were significantly more active during recess.

Most education departments allow individual schools decide dress code, even though they often have a provision that the guidelines must comply with anti-discrimination policies. In New South Wales, by way of instance, the department says that rules should adapt the “diverse nature of the student population from the school and not disadvantage any student.”

Due to the ambiguity in language, Dr. Mergler said, colleges can claim they’re complying with the code simply by providing boys and girls uniforms. Automobiles in Queensland continue to lobby for an amended policy following an attempt to permit women to wear trousers was rejected in May.

In Victoria, a request to modify the policy has attracted over 20,000 signatures.

Sofia’s letter pleading for change to the dress code in Western Australia.

Most arguments appear to rest on tradition.




“I think heritage plays a strong role in our schools, and we frequently wish to honor these traditions,” Mr. Henderson said. His school will offer the choice to wear trousers, he said, but that should be for colleges to decide on an individual basis.

“Surely in private schools, there is an element of longstanding conventions and parents occasionally thinking, ‘I went to this school and that I wore that dress, and I’d like my daughter to wear this dress,”’ Dr. Mergler said.

When she first broached the concept of amending the dress code at her daughter’s school, some parents defended skirts as a means to accustom women to wearing dresses at work.

“In the actual world, girls get to choose,” Dr. Mergler said. “I choose now whether I wear trousers or skirts, and we need women to have the same option at colleges.”

In terms of Sofia Myhre, her mother said that the exercise was a fantastic lesson in effecting change.

“Holy Grail” Metallic Hydrogen Is Going to Change Everything

“Holy Grail” Metallic Hydrogen Is Going to Change Everything

Taken From Nasa Website

Two Harvard scientists have succeeded in creating an entirely new material long thought to be the “holy grail” of physics — metallic hydrogen, a substance of unparalleled energy that could one day propel people into deep space.

This broke down the molecule from its solid state and enabled the particles to dissociate into atomic hydrogen.

The ideal rocket fuel we now have is liquid hydrogen and liquid oxygen, burnt for propellant. The efficacy of these substances is characterized by “specific impulse,” the measure of impulse gas may give a rocket to propel it forward.

“People at NASA or the Air Force have advised me that if they could find an increase from 450 seconds [of particular impulse] to 500 minutes, which would have a enormous effect on rocketry,” Isaac Silvera, the Thomas D. Cabot Professor of the Natural Sciences at Harvard University, told Inverse by telephone. “If you are able to activate metallic hydrogen to recover to the molecular stage, [the energy release] calculated for that’s 1700 seconds.”

Metallic hydrogen could potentially enable rockets to get into orbit in one point, even allowing individuals to explore the outer planets. Metallic hydrogen is called to be “metastable” — meaning if you make it in a really significant pressure then release it, it is going to remain at that pressure. A diamond, for instance, is a metastable form of graphite. If you choose graphite, pressurize it, then heat it, it will become a diamond; should you take off the pressure, it is still a diamond. But if you heat it again, it is going to revert back to graphite.

Scientists first theorized atomic rust a century ago. Silvera, who created the material together with post-doctoral fellow Ranga Dias, was pursuing it since 1982 and working as a professor of physics at the University of Amsterdam.

Metallic hydrogen has also been called to be a high- or maybe room-temperature superconductor. There are no other known room-temperature superconductors in existence, meaning the software are immense — particularly for the electrical grid, that suffers for energy lost through heat dissipation.

It might also facilitate magnetic levitation for autonomous high-speed trains; considerably improve performance of electrical cars; and reevaluate the way energy is generated and stored.

But that is all still likely a few decades off. The next step concerning practical application is to find out if metallic hydrogen is really meta-stable. If the substance does prove to be meta-stable, it may be used to make room-temperature crystal clear and — by spraying atomic hydrogen on the surface –use it like a seed to grow longer, how synthetic diamonds are created.
