On 20 April 1989 Nature published an article by Dr John Talent accusing "one Indian scientist" of corrupting the palaeontological literature on the Himalayas. Below, that scientist — Professor V. J. Gupta — replies. On pp.13–16 appear four other articles, each of them prompted by the appearance in print of Talent's allegations.
The articles printed below are by co-authors of some of the papers called into doubt by Talent. Two are by close colleagues of Gupta at the Centre of Advanced Study in Geology at Panjab University.
Most accounts of chaotic dynamical systems are based on numerical computations of some kind. But now there is a welcome sign that verbal arguments may make these studies more accessible.
The environmental scanning electron microscope (SEM) eliminates the high-vacuum requirement of conventional SEM, allowing the analysis of unprepared, wet samples.
Atroubleshooting modem linkfor EM hardware and a high-sensitivity imaging plate for TEMs are a few of the new ideas for microscopy that can be seen at EMAG-MICRO '89 in London next week.
