GRANDKILO: IT CHANGES EVERYTHING EVEN IF NOTHING, OR ALMOST NOTHING, CHANGES.

For the series, maybe not everyone knows that, today we are talking about a news item that appeared in newspapers a few weeks ago that will change inexorably the history of measurement systems in relation to its references. Yes because as of May 20, the GrandKilo the platinum-iridium cylinder reference of the kilogram preserved in Paris, replaced by Sophisticated algorithms studied for years that refer to physical and mathematical constants adjusted by the laws of the universe. The question of replacing the GrandKilo, has been debated for years by scientists around the world who, having verified the albeit microscopic weight variation of the object kept in a double glass case due to its normal chemical/physical decay, have been engaged in research to define a new constant that could meet all precision requirements. As stated byINRIM ( National Institute of Metrology) President Diederik Wiersma, this will be a momentous change, which, however, will not result in any shake-up, we will not in fact have to recalibrate our scales or measuring instruments in every area starting with daily spending, over time instead to benefit will be measures related to very small quantities, they will in fact be able to gain in precision areas such as the electronics industry, the pharmaceutical industry and the applications of nanotechnology. Fascinating statement that if “Martians” landed on earth tomorrow morning, these could safely use the weight unit  Kilo current because it refers to universal laws of physics and no longer to a sample physical object established by earthlings. For those who want to learn more can find at this link, the video of the conference that was held two days before the official change at the headquarters of the INRIM. As far as we are concerned, nothing changes, we like to think, however, that as far as the weighing systems and calibrations we carry out every day in our laboratories are concerned, we too are part of and will be part of an extraordinary future, it is no coincidence that our claim is: WE WEIGH THE FUTURE.
