Editorial

Asian Journal of Physics has completed six volumes of its existence from the time since the first issue was launched. It has been possible to bring out the AJP issues at regular intervals because of enthusiastic response from the scientists of different parts of the globe, specially from the third world. AJP is serving, with its humble effort, its purpose of publishing and spreading new results in diverse fields of physics and allied topics, with specific emphasis on the Indian scene.

 

The appearance of the comet Hale Bopp in the north west sky in the evening during early part of the year 1997 created considerable interest among the professional and amateur astronomers. The comet was an unusual type as compared to other known comets. It had a bigger coma (comet atmosphere) with time period of revolution of 4000. years. AJP has the credit of carrying the only one article about the photographing the spectrum of the coma of the comet Hale-Bopp in one of its 1997 numbers.

 

In order to expedite the publication and to extend coverage of several important areas, we have included a few more names in the Editorial Board of AJP. In the present volume 7 (1998), we plan to bring out two special issues of AJP. One on Raman spectroscopy and the other on Non-linear dynamics in optics.

We do hope that AJP will increasingly rise up to meet your expectations. The refereeing is now quicker and we shall keep on seeking to reduce the refereeing time further.

In the end, our Editorial/Advisory Board wishes you a very Happy New Year.
