Prasad Perlekar Rajaram Nityananda
Steven Vogel was a pinoneer in applying principles of mechanics to diverse living systems. This article first provides a brief overview of his career. It then reviews the concepts of P´eclet number and Reynolds number which are helpful in appreciating the Classics article by Vogel reproduced in this issue.

Measuring the Sizes of Stars: Fringe Benefits of Interferometry
Stars, other than the Sun, appear to our unaided eyes aspoints of light. Large telescopes show an image whose sizeis dictated by refractive index irregularities in the Earth’s atmosphere.The size of this blurring is much greater than thatof the star, and hence it is difficult to measure the stellar size.Fizeau showed how one might overcome this limitation usingthe two-slit interference technique. It was Michelson whocarried out this programme and made the first direct measurementof the giant star Betelguse in the constellation ofOrion. His value for the angular diameter, 47 milliarcsecondsor 2.6×10−7 radians, was completely confirmed by laterwork following his methods. The key concept introduced was
‘fringe visibility’, which turned out to be very fruitful in thelater development of optics as well as astronomy.

The Rayleigh-Taylor Instability Among the Stars
The instability of the interface separating a denser fluid froma lighter one below it has applications to the surroundings ofmassive stars – both when they are born and when they die.

A Black Hole Finally (Un)Seen in the Centre of a Galaxy:The Sharpest Image Ever
The uneven ring of radio emission at the centre of the distantgalaxy,M87, has excited astronomers, physicists, and thegeneral public, as the first view of a black hole. Everythingabout the project, known as the EHT – Event Horizon Telescope
– is extreme. The observation combines signals fromradio telescopes distributed over an entire hemisphere, operatingat millimetre wavelengths on high mountains and atthe Earth’s poles. These telescopes are synchronised by thebest atomic clocks, and massive amounts of data recordingand number crunching were needed. To interpret the results,elaborate models of the energy source, based on Einstein’sgeneral theory of relativity (GTR) were constructed.The team had over three hundred scientists from more thana hundred institutions, some of whom worked for nearly adecade towards this goal.

G N Lewis and Special Relativity: A Little Known Side of a Great Chemist
In 1909, Lewis and Tolman, then physical chemists at theMassachusetts Institute of Technology, wrote a paper whichbuilt on an earlier paper by Lewis. This gave amoremechanicsbasedapproach to the subject, in contrast to Einstein’s originalwork which drew on electrodynamics. This work playeda significant role in the early development of special relativitytheory, then only four years old and still under heated discussionworldwide. This paper with Tolman, though a relativelyminor part of Lewis’s overall work, has historical and pedagogicalvalue and gives a glimpse of his breadth, early growthand influence as a scientist. The present article outlines thearguments of their 1909 paper, and places it in context.

Mathematics of Securing a Box With a Single Rubber Band
Jayanth Vyasanakere P Rajaram Nityananda
In this article, we study the configuration of a rubber bandwrapped around a (sweet) box. The rubber band is a looptrying to attain minimum length. We, therefore, study suchcurves, also known as closed geodesics, on a cuboid whichis the typical shape of such a box. The arguments should beaccessible even to a high school student, while the conclusionshave elements of surprise and hence interest.

Optimal Extraction of Heat: An Instructive Problem
Jayanth Vyasanakere P Rajaram Nityananda
In this article, we pose a challenge concerning an optimal algorithm for transferring heat from a hot liquid to a cold one. The solutions discussed here demonstrate the usefulness of choosing the right variables. We illustrate different possible approaches---algebra, calculus, and numerical simulation--each of which has its charm. Instructors can make good use of this to illustrate multiple methods of problem-solving in an undergraduate classroom.
