Versailles, Nov 17 (AP/UNB) — In a historic vote, more than 50 nations unanimously approved an overhaul of the international measurement system that underpins global trade and other human endeavors, uniting Friday behind new definitions for the kilogram and other units in a way they fail to do on many other issues.
Scientists, for whom the update represented decades of work, clapped, cheered and even wept as delegates gathered in Versailles one by one said "yes" or "oui" to the change, hailed as a revolution in how humanity measures and quantifies its world.
The redefinition of the kilogram, the globally approved unit of mass, was the mostly hotly anticipated change. For more than a century, the kilogram has been defined as the mass of a cylinder of platinum-iridium alloy kept in a high-security vault in France. That artefact, nicknamed "Le Grand K," has been the world's sole true kilogram since 1889 .
Now, with the vote, the kilogram and all of the other main measurement units will be defined using numerical values that fit handily onto a wallet card. Those numbers were read to the national delegates before they voted. The update will take effect May 20.
Scientists at the meeting were giddy with excitement: some even sported tattoos on their forearms that celebrated the science.
Nobel prize winner William Phillips called the update "the greatest revolution in measurement since the French revolution," which ushered in the metric system of meters and kilograms.
The Grand K and its six official copies, kept together in the same safe on the outskirts of Paris and collectively known as the "heir and the spares," will be retired but not forgotten. Scientists want to keep studying them to see whether their masses change over time.
The update will have no discernable impact for most people. Bathroom scales won't suddenly get kinder and kilos and grams won't change in supermarkets.
But the new formula-based definition for the kilogram will have multiple advantages over the precision-crafted metal lump that set the standard from the 19th century to the 21st, through periods of stunning human achievement and stunning follies, including two world wars.
Unlike a physical object, the formula for the kilo, now also known as "the electric kilo," cannot pick up particles of dust, decay with time or be dropped and damaged, but will be easier to share.
"If we stay where we are, and someone did accidentally drop the kilogram or if there was a contamination that we couldn't control, then the whole system has got no head. We're in chaos," said Barry Inglis, a scientist from Australia. "That's the thing that's really been worrying us, I think, for maybe 15 years or more is just how vulnerable the system is, by depending just on that one little piece of platinum-iridium."
The redefined kilo is expected to allow for more accurate measurements of very, very small or very, very large masses and help usher in innovations in science, industry, climate study and other fields. In humankind's efforts to quantify and understand the world, stretching back centuries to when ancient Babylonians measured mass with stones, the vote marked a major milestone, scientists agreed.
"Those units, those constants chosen now, include everything we know, everything we have always known and provide that springboard for us to go pursue those things that we don't know," said Jon Pratt of the U.S. National Institute of Standards and Technology. He said Friday's gathering "was just leaving me in a puddle of tears."
Updated definitions for the ampere, kelvin and mole also were approved Friday.
Humanity uses seven main measurements units: the meter for length, the kilogram for mass, the second for time, the ampere for electric current, the kelvin for temperature, the mole for the amount of a substance and the candela for luminous intensity.
Of the seven, the kilo was the last still based on a physical artefact, Le Grand K. With time, as the science behind the new kilo definition becomes more accessible and affordable, the update should also mean that countries won't have to send their own kilograms back to France to be checked occasionally against Le Grand K, as they have done until now, to see whether their mass was still accurate.
"We future-proofed the system," said Martin Milton, director of the International Bureau of Weights and Measures.
The bureau is the guardian of the system, as well as of Le Grand K and its copies, which are stored in a vault that requires three keys, kept by three different people, to unlock. Very rarely have they seen the light of day.
"We put in place a system that doesn't depend on something that is 140 years old," Milton said.
Dhaka, Nov 17 (UNB) -After many a leak, PUBG PS4 has finally been revealed. The battle royale sensation has officially been listed on Amazon along with how much it costs and when it will be playable. The PUBG PS4 release date is December 7 the world over, reports NDTV.
As for the PUBG PS4 price, it starts from $30 and is available on disc. With PUBG hitting the PS4, it makes Sony's console the second one to get the game after a yearlong period of exclusivity on the Xbox One. To celebrate PUBG coming to the PS4, Sony announced several editions of the game. These include PUBG PS4 on disc, Looter's Digital Edition, Survivor's Digital Edition, and the Champion's Digital Edition. PUBG PS4 pre-order bonuses include skins from Uncharted and The Last of Us.
PUBG PS4 bundles and price
Includes: Base Game for $30 (around Rs. 2,100)
Looter's Digital Edition
Includes: Base Game for $30 (around Rs. 2,100)
Survivor's Digital Edition
Includes: Base Game, Vikendi Event Pass, 2,300 G-Coin Pack, 20,000 BP for $50 (around Rs. 3,500)
Champion's Digital Edition
Includes: Base Game, Vikendi Event Pass, 6,000 G-Coin Pack, 20,000 BP (around Rs. 4,200)
PUBG PS4 India price
Right now the India PS Store doesn't have a PUBG PS4 price yet. However if we go by past $30 conversions for India on the PS Store, it should work out to Rs. 2,081 much like other $30 games such as Thronebreaker: The Witcher Tales. The Survivor Digital Edition should be Rs. 3,499, while the Champion's Digital Edition price should be Rs. 3,999, in line with $50 and $60 game prices on India PSN.
It's unclear if PUBG PS4 on disc is making it to India either seeing that developer PUBG Corp doesn't have a local presence. Sony could handle distribution duties. Gadgets 360 has got in touch with Sony India for comment and will update this story if we hear from the company.
Last week, members of video gaming forum ResetEra unearthed a post from October in a separate PlayStation forum called PSNProfiles, wherein a user claimed that PUBG was in their PS4's game database.
“Don't know when it's coming out, but it's already on Sony servers, hosting the game image and Content-ID for the PSN store,” the PSNProfiles member added, with two individual content IDs for North America and the US. Both currently display a 404 error.
In the same ResetEra thread, video games analyst Daniel Ahmad said that PUBG would be out next month on PS4, with other users suggesting it points to a one-year exclusivity deal for Microsoft and Bluehole, the South Korean parent company of PUBG Corp.
Versailles, Nov 15 (AP/UNB) — In a historic vote, nations unanimously approved Friday a ground-breaking overhaul to the international system of measurements, coming together in a way that they fail to do on so many other issues behind new definitions for the kilogram and other key units vital for trade and science.
Scientists for whom the update represents decades of work clapped, cheered and even wept as the 50-plus nations one by one said "yes" or "oui" to the update.

Nobel prize winner William Phillips called it "the greatest revolution in measurement since the French revolution," which ushered in the metric system of meters and kilograms.
The so-called "Grand K" kilogram, a cylinder of polished platinum-iridium alloy that has been the world's sole true kilo since 1889, is to be retired.
Nations gathered in Versailles, west of Paris, instead approved the use of a scientific formula to define the exact weight of a kilogram. Scientists at the meeting were giddy with excitement: some even sported tattoos on their forearms to mark the moment.
The change will have no discernable impact for most people. Their bathroom scales won't get kinder and kilos and grams won't change in supermarkets.
But it will mean redundancy for the Grand K and its six official copies. The new formula-based definition of the kilogram will have multiple advantages over the precision-crafted metal lump that has set the standard for more than a century.
Unlike a physical object, the formula cannot pick up particles of dust, decay with time or be dropped and damaged. It also is expected to be more accurate when measuring very, very small or very, very large masses.
Even in retirement, the "Grand K" and its six official copies — collectively known as "the heir and the spares" — will still be kept in the high-security vault on the outskirts of Paris where they are stored. That's because scientists want to keep on studying them, to see whether their masses gradually change over time.
Only exceedingly rarely have they seen the light of day since 1889, when they were taken out on a very few occasions to check whether other master kilograms that nations around the world use were still accurately calibrated, give or take the mass of a dust particle or two.
The metal kilo is being replaced by a definition based on Planck's constant, which is part of one of the most celebrated equations in physics but also devilishly difficult to explain.
Suffice to say that the updated definition will, in time, spare nations the need to occasionally send their kilos back to France for calibration against the "Grand K." Scientists instead should be able to accurately calculate an exact kilo without having to measure one lump of metal against another.
Dhaka, Nov 16 (UNB) -The Delhi High Court on Wednesday sought the Centre's response on a plea for removal of vulgar and sexually explicit content from online platforms like Netflix, Amazon Prime Video, and others.
A bench of Chief Justice Rajendra Menon and Justice V. Kameswar Rao listed the matter for further hearing on February 8, reports NDTV.
The petition was filed by NGO, Justice for Rights. Advocate Harpreet S. Hora appearing for the NGO sought a law or guidelines for regulating such contents available like Netflix, Amazon Prime Video, and other similar platforms.
The petitioner said online platforms offered vulgar, sexually explicit, pornographic, profane, virulent, religiously forbidden and morally unethical contents in order to attract more subscribers and generate profit.
The NGO alleged that most of the contents available was in violation of the Indian Penal Code and the Information Technology Act.
