In computational complexity theory, SC (Steve's Class, named after Stephen Cook) is the complexity class of problems solvable by a deterministic Turing machine in polynomial time (class P) and polylogarithmic space (class PolyL) (that is, O((log n)k) space for some constant k). It may also be called DTISP(poly, polylog), where DTISP stands for deterministic time and space. Note that the definition of SC differs from P ∩ PolyL, since for the former, it is required that a single algorithm runs in both polynomial time and polylogarithmic space; while for the latter, two separate algorithms will suffice: one that runs in polynomial time, and another that runs in polylogarithmic space. (It is unknown whether SC and P ∩ PolyL are equivalent). DCFL, the strict subset of context-free languages recognized by deterministic pushdown automata, is contained in SC, as shown by Cook in 1979. It is open if all context-free languages can be recognized in SC, although they are known be in P ∩ PolyL. It is open if directed st-connectivity is in SC, although it is known to be in P ∩ PolyL (because of a DFS algorithm and Savitch's theorem). This question is equivalent to NL ⊆ SC. RL and BPL are classes of problems acceptable by probabilistic Turing machines in logarithmic space and polynomial time. Noam Nisan showed in 1992 the weak derandomization result that both are contained in SC. In other words, given polylogarithmic space, a deterministic machine can simulate logarithmic space probabilistic algorithms. (Wikipedia).

Schrödinger Equation : its impact on the electron and the atom
The Schrödinger Equation is fundamental to the quantum behaviour of the atom, and quantum mechanics in general. But what is it all about? In this video I discuss what it means, without delving too deeply in the mathematics, and how it helps understand the nature of the electron in the atom
