points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

We continue the study of the Floquet (spectral) theory of the beam equation, namely the fourth-order eigenvalue problem $[a(x)u^{\prime \prime}(x)]^{\prime \prime}=\lambda \rho (x)u(x),\quad \quad ...

For a 'street science' experiment I approached holidaymakers with a ping-pong ball and a funnel, to show them a classic and counterintuitive science demonstration. It involves something known as ...
