The idea of ‘spontaneous generation’ of life comes under rigorous scrutiny — with the help from an unexpected quarter, the
advent of microscopy. 相似文献

In mankind’s quest for knowledge, spanning the last four thousand years, certain developments stand out as milestones in the
progress of science. This new series, intended for the general reader, will highlight such key events in the growth of mathematics,
physics, chemistry, biology and engineering in an approximately chronological manner. 相似文献

It is well known in Newtonian gravity that a spherically symmetric density distribution produces a force outside it which
falls as the square of the distance. Surprisingly, the converse is not true! Just be cause the force falls as inverse square
outside a density distribution, you cannot conclude that it must be spherically symmetric. This article, first in a new series,
explores this and related issues.
This is based on an article originally published by the author in Physics Education, Vol 22, No. 4, p.263, 2006.

Scaling arguments and dimensional analysis are powerful tools in physics which help you to solve several interesting problems.
And when the scaling arguments fail, as in the examples discussed here, we are led to a more fascinating situation.

Discovering unexpected connections between completely different phenomen a is always a delight in physics. In this and the
next installment, we will look at one such connection between two unlikely phenomena: propagation of light and path integral
approach to quantum mechanics!

A solution to the 3-body problem in gravity, due to Lagrange, has several remarkable features. In particular, it describes
a situation in which a particle, located at the maxima of a potential, can remain stable against small perturbations. 相似文献

The vacuum state of the electromagnetic field is far from trivial. Amongst other things it can exert forces that are measurable
in the lab, in a curious phenomenon known as Casimir effect.
