- Today, in a landmark decision, representatives from 60 countries voted to redefine the SI, changing the world’s definition of the kilogram, ampere, kelvin and mole, forever! #SIRedefinition
00:00 - The Earth is spinning faster now than at any time in the last 50 years. Peter Whibberley, Senior Research Scientist at NPL, discusses whether a negative leap second may be needed so atomic clocks can align correctly with the turning world @Telegraph
- Happy #WorldMetrologyDay! The #SIRedefinition has been approved and from today the definitions of four of the seven base SI units will change. Let's explore them: npl.co.uk/campaigns/worl…
- We were honoured to welcome HRH The Princess Royal at SPIE #Photonex today. It was a great opportunity to show our world-leading expertise and cutting-edge facilities that means end-users, system integrators and investors can have confidence in new quantum products and services.
- This is the world’s smallest #Christmas card, made here at NPL. You could fit more than 200 million on a single postage stamp!
GIF - Congratulations to @Paddy_Regan on becoming an NPL Fellow! Regan joined NPL as the UK's first Professor of Nuclear Metrology, joint with @UniOfSurrey & is being acknowledged for his scientific leadership in the field of nuclear and radiation physics. npl.co.uk/news-and-press…
- Today is World Metrology Day! This year the theme is 'Constant evolution of the International System of Units (SI)'. Find out how measurement plays a vital role in all our lives. #WorldMetrologyDay #Metrology npl.co.uk/world-metrolog…
- Have you ever wondered how the #kilogram is measured? Join us @royalsociety #summerscience exhibition to learn more #SIRedefinition
- It’s an exciting day for measurement! At the 26th General Conference on Weights and Measures in Versailles in Paris, #measurement scientists from around the world will come together to vote on the redefinition of the #SIUnits. Watch here at 10 am: bipm.org/en/the-si/
- Alan Turing was born #OnThisDay in 1912. The work Turing did on the Automatic Computing Engine (ACE) while based at NPL placed us as one of the world leaders in computing development in the 1940s and 1950s npl.co.uk/about/history/…
- We're THIS excited about the #SIRedefinition! The changes, which will come into force on 20 May 2019, will bring an end to the use of physical objects to define measurement units. npl.co.uk/news/internati…
00:00 - Today, on #WorldMetrologyDay, the world says goodbye to the original kilogram as the redefinition of the SI base units comes into force. Find out more here: npl.co.uk/news/science-l… #SIRedefinition
- Alan Turing will be the face of the new £50 note! @bankofengland The work Turing did on the Automatic Computing Engine (ACE) while based at NPL placed us as one of the world leaders in computing development in the 1940s and 1950s. npl.co.uk/famous-faces/a…
