Science education in England is generally regulated at all levels for assessments that are England's, from 'primary' to 'tertiary' ( university ). Below university level, science education is the responsibility of three bodies: the Department for Education, Ofqual and the QAA, but at university level, science education is regulated by various ...
In foundation-tier papers, pupils can obtain a maximum grade of a C, while in a higher-tier paper they can achieve a minimum grade of a D. Higher-tier candidates who miss the D grade by a small margin are awarded an E. Otherwise the grade below E in these papers is U. In untiered papers pupils can achieve any grade in the scheme.

In 1951, a milestone article in quantum chemistry is the seminal paper of Clemens C. J. Roothaan on Roothaan equations. [103] It opened the avenue to the solution of the self-consistent field equations for small molecules like hydrogen or nitrogen. Those computations were performed with the help of tables of integrals which were computed on the ...
