The Nobel Prize in Chemistry for the year 2016 was awardedto three illustrious chemists, Professors Jean-Pierre Sauvage,Sir Fraser Stoddart, and Ben Feringa. Pioneering works ofthese chemists on designing molecules, chemically synthesizingthem, and extracting a work out of such designedmoleculesopen-up a new area of chemistry in a paradigm shifting manner.Beginning with controlling the molecular motions, particularlyinvolving interlocked macrocycles in late 1980s, theadvancement progressed to envelop energy storage and retrieval,and varieties of examples around the concept. Molecularmotion alone can also be a rich source for such a workoutput has also been established. These developments possessthe required momentum to uncover a new area of chemistry,wherein energy input-output can be used beneficially to conducta useful work, in a close analogy to machines such as anelectric motor.

The brachistochrone problem posed by Bernoulli and its solutionhighlights one of the most famous experiments in physicswhich illustrates the variational principle. This pedagogicalstudy is designed to ignite a classroom discussion on the variationalproblem. We overview the Euler–Lagrange formalismof the variational principle and obtain the solution to thebrachistochrone problem. We demonstrate the success of thevariationalmethod using brachistochronemodels which werefabricated specially for this purpose.

The vibrating string problem is the source of much mathematicsand physics. This article describes Lagrange’s formulationof a discretised version of the problem and its solution.This is also the first instance of an eigenvalue problem.
