Nuclear physics is basically just the study of the complex outcomes of weak interaction + quantum chromodynamics.

Classification of second order partial differential equations into elliptic, parabolic and hyperbolic by Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01
Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01One major application of this classification is that different boundary conditions are suitable for different types of partial differential equations as explained at: which boundary conditions lead to existence and uniqueness of a second order PDE.

How can a chemical substance be unstable but not flammable? by Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01
Ciro Santilli 35 Updated 2025-01-10 +Created 1970-01-01I can't believe there isn't a YouTube video comparing various substances for each flammability and instability ratings, this would be a huge hit.
Oh, and if it weren't enough, mathematicians have a separate name for the damned nabla symbol : "del" instead of "nabla".
TODO why is it called "Del"? Is is because it is an inverted uppercase delta?
