In mathematics, the structure constants or structure coefficients of an algebra over a field are used to explicitly specify the product of two basis vectors in the algebra as a linear combination. Given the structure constants, the resulting product is bilinear and can be uniquely extended to all vectors in the vector space, thus uniquely determining the product for the algebra. Structure constants are used whenever an explicit form for the algebra must be given. Thus, they are frequently used when discussing Lie algebras in physics, as the basis vectors indicate specific directions in physical space, or correspond to specific particles. Recall that Lie algebras are algebras over a field, with the bilinear product being given by the Lie bracket or commutator. (Wikipedia).

How an Equilibrium Constant varies with Temperature - Thermodynamics - Physical Chemistry

Fine Structure Constant Explained in 60 Seconds (Part 1) #shorts by Parth G
#shorts - the Fine Structure Constant (alpha) is a fundamental constant of nature. It is often known as the coupling constant of the electromagnetic force, and is dimensionless, with a value of approximately 1/137. It shows up a lot in the mathematics behind physics, but there's a reason

How to calculate theoretical density for crystal structures
Theoretical density calculations are important. Real density values can deviate slightly from these calculations because of voids, vacancies, cracks etc. However, they provide a good approximation. We calculate density from mass divided by volume. We can determine mass by taking the molecu
