About the Cover

Stephen Hawking, one of the most brilliant theoretical physicists in history, wrote the modern classic A Brief History of Time to help non-scientists understand fundamental questions of physics. He was born January 8, 1942 in Oxford, England. From an early age, he showed a passion for science and the sky. At age 21, while studying cosmology at Cambridge, Hawking was diagnosed with Amyotrophic Lateral Sclerosis (ALS). Despite his debilitating illness, he has done ground-breaking work in physics and cosmology and his several books strive to make science accessible to everyone. After completing his doctorate in 1966 Hawking was awarded a fellowship at Gonville and Caius College, Cambridge. At first his position was that of Research Fellow, but later he became a Professorial Fellow at Gonville and Caius College. In 1973 he left the Institute of Astronomy and joined to the Department of Applied Mathematics and Theoretical Physics at Cambridge. He became Professor of Gravitational Physics at Cambridge in 1977. In 1979 Hawking was appointed Lucasian Professor of Mathematics at Cambridge. From 1970 Hawking began to apply his previous ideas to the study of black holes. Continuing this work on black holes, Hawking discovered in 1970 a remarkable property. Using quantum theory and general relativity he was able to show that black holes can emit radiation. His success with proving this made him work from that time on combining the theory of general relativity with quantum theory.

DISCOVERY OF THE MONTH

A prospective approach on Scarlet fever

Balasubramanian J, Vijayakumar N

Scarlet fever is caused by an infection with group A streptococcus bacteria. The bacteria make a toxin (poison) that can cause the scarlet-colored rash from which this illness gets its name. Not all streptococci bacteria make this toxin and not all kids are sensitive to it. Two kids in the same family may both have strep infections, but one child (who is sensitive to the toxin) may develop the rash of scarlet fever while the other may not.

Blended learning: issues and concerns

Ruba Abu Hassana

Blended learning is being recognized as a solution to the perceived weaknesses in both traditional learning and e-learning. This paper discusses the opportunities provided by blended learning, in comparison with both traditional and e-learning, and the dimensions that must be considered in order to create the best blend. The review shows that blended learning is not a new concept, but that it exists in many different forms and is prevalent in most classroom practices.

Catalyst for epoxidation of oils: a review

Harshal Patil, Jyotsna Waghmare

This review focused on the finding of the potential utility of epoxidized vegetable oil and developing newer means for its wide spread applications. Vegetable oil finds sustainable and renewable source of raw material. The unsaturation present in vegetable oils can be chemically modified to a value added product by a complicated reaction called ‘epoxidation’.
