Parsing is the process of analyzing a sequence of symbols, typically in the form of text or code, to determine its grammatical structure according to a set of rules. This process is essential in various fields such as computer science, linguistics, and data processing. In computer science, particularly in programming language interpretation and compilation, parsing involves breaking down code into its component parts and understanding the relationships between those parts.

As of my last knowledge update in October 2023, "Sinyan Shen" may refer to an individual or could be associated with a certain context that isn't widely recognized or documented in readily available sources.

In 1962 Brian Josephson published his inaugural paper predicting the effect as Section "Possible new effects in superconductive tunnelling".

In 1963 Philip W. Anderson and John M. Rowell published their paper that first observed the effect as Section "Possible new effects in superconductive tunnelling".

Some golden notes can be found at True Genius: The Life and Science of John Bardeen page 224 and around. Philip W. Anderson commented:

As part of the course Anderson had introduced the concept of broken symmetry in superconductors. Josephson "was fascinated by the idea of broken symmetry, and wondered whether there could be any way of observing it experimentally."

The partial differential equation of non-relativistic quantum mechanics.

Experiments explained:

Experiments not explained: those that the Dirac equation explains like:

To get some intuition on the equation on the consequences of the equation, have a look at:

The easiest to understand case of the equation which you must have in mind initially that of the Schrödinger equation for a free one dimensional particle.

Then, with that in mind, the general form of the Schrödinger equation is:where:

The $\overrightarrow{x}$ argument of $\psi$ could be anything, e.g.:Note however that there is always a single magical $t$ time variable. This is needed in particular because there is a time partial derivative in the equation, so there must be a corresponding time variable in the function. This makes the equation explicitly non-relativistic.

The general Schrödinger equation can be broken up into a trivial time-dependent and a time-independent Schrödinger equation by separation of variables. So in practice, all we need to solve is the slightly simpler time-independent Schrödinger equation, and the full equation comes out as a result.

Quantum yield is a measure of the efficiency of a photophysical or photochemical process, defined as the ratio of the number of events of a specific type (such as emitted photons, formed molecules, etc.) to the number of photons absorbed. It is a dimensionless quantity often expressed as a decimal or a percentage.
