Entropy of a chemical reaction by Ciro Santilli 35 Updated +Created
First, experiments, please how do you determine it and how it helps predict the future: chemistry.stackexchange.com/questions/42066/is-there-a-way-to-experimentally-measure-entropy
No YouTube video? Really?

Plutonium by Ciro Santilli 35 Updated +Created
What a material:
  • only exists in trace amounts in nature,but it can be produced at kilogram scale in breeder reactors
  • it is only intentionally produced for one application, and one application only basically: nuclear weapons

Time dependent boundary condition by Ciro Santilli 35 Updated +Created
Most commonly, boundary conditions such as the Dirichlet boundary condition are taken to be fixed values in time.
But it also makes sense to think about cases where those values vary in time.

Consistency by Ciro Santilli 35 Updated +Created
A set of axioms is consistent if they don't lead to any contradictions.
When a set of axioms is not consistent, false can be proven, and then everything is true, making the set of axioms useless.

Proper motion by Ciro Santilli 35 Updated +Created
Some stars are so close that we can actually see their angles move with time due to the relative motion between them and the Sun, e.g. Proxima Centauri!
Identity theorem by Ciro Santilli 35 Updated +Created
Essentially, defining an holomorphic function on any open subset, no matter how small, also uniquely defines it everywhere.
This is basically why it makes sense to talk about analytic continuation at all.
One way to think about this is because the Taylor series matches the exact value of an holomorphic function no matter how large the difference from the starting point.
Therefore a holomorphic function basically only contains as much information as a countable sequence of numbers.
