THIS “Introduction to Vector-methods and their Various Applications to Physics and Mathematics” is an exposition of the late Willard Gibbs' vector analysis. The author in his preface warns us that “no ...
The vector \(2k\) is twice as long as the vector \(k\). Double each number in \(k\) to get \(2k\). \(\mathbf{2k} = \begin{pmatrix} 6 \\ -4 \end{pmatrix}\) \(\mathbf{m ...
Back in 1948, the journal Physical Review published a paper entitled “Space-Time Approach to Quantum Electrodynamics” by a young physicist named R.P. Feynman at Cornell University. The paper described ...
