Happy birthday, Lord Kelvin. It’s World Refrigeration Day.
Lord Kelvin was born 199 years ago: June 26th, 1824. 26 June is also World Refrigeration Day.
May 20 is World Metrology Day, commemorating the anniversary of the signing of the Metre Convention in 1875.
The theme for World Metrology Day 2023 is Measurements supporting the global food system. This theme was chosen because of the increasing challenges of climate change, and global distribution of food in a world whose population reached 8 billion at the end of 2022.

Happy Ada Lovelace Day 2022!
Ada Lovelace Day (ALD) is an international celebration of the achievements of women in science, technology, engineering and maths (STEM). It aims to increase the profile of women in STEM and, in doing so, create new role models who will encourage more girls into STEM careers and support women already working in STEM.
It took a while, maybe partly due to COVID19, including fewer meetings and activities, we also had to send the Spec Documents again with different dates, but thanks everyone for getting the last deliverables out there now.
