What is Specific: Definition and 1000 Discussions

The Sustainable Product Engineering Centre for Innovative Functional Industrial Coatings (SPECIFIC) is an academic and industrial consortium led by Swansea University, with Tata Steel as the main industrial partner. It is funded by EPSRC, Innovate UK and the Welsh Government.The centre is developing the concept 'Buildings as Power Stations' and has been awarded £26 million, comprising £15 million from the EU, with the remaining money coming from EPSRC, Innovate UK, industry partners, and contributions from Swansea and Cardiff universities.
SPECIFIC has developed an 'Active Classroom', designed by architect Joanna Clarke and situated at Swansea University Bay Campus, showcasing innovative technologies for creating low carbon buildings which generate more energy than they consume. The Active Classroom won the Construction Excellence in Wales Award for Innovation in 2017.In 2018 the UK government announced £36 million funding for an Active Building Centre in order to accelerate market adoption of active buildings.

    I Specific question re Bayesian statistics/analysis

    I am reading "Thinking Fast and Slow" (fantastic book by the way) and I ran across a statement that has me flummoxed. The justification for the statement was said to be "Bayesian analysis" so I looked into that and frankly it's just more than I want to get into so I'm wondering if someone can...

    Oddly specific number of elements

    There are 118 elements known to man, and some scientists like Feynman think that element 137 might be the end of the Periodic Table. Isn't that oddly specific? To me, it feels like it is completely random and of no significance. What is going on here? Is there a constant that relates to this...
