NUCLEAR PROPERTIES


An atomic nucleus is a bound quantum state which is capable to exist in variable quantum states characterized by their different properties. It constitutes two different elementary particles known as protons and neutrons. These elementary particles are jointly known as nucleons. The atomic nucleus generally exists in the lowest energy state also known as ground state. The properties corresponding to these ground states are known as static properties whereas the dynamic properties are those which are characterized during nuclear reactions, nuclear decay and nuclear excitation.

In this article we will discuss the static properties of nuclei.

Indian Space Research Organization


Indian Space Research Organization (ISRO) was established in August 1969 by two pioneer scientists of India – Vikram Sarabhai and Homi Bhabha with a vision to harness space technology for national development, while pursuing space science research exploration. Headquarter of ISRO is in Antariksh Bhavan, Bangalore. ISRO successfully launched its first satellite Aryabhata in 1975 with the help of space launching vehicle of Soviet Union. However, Rohini was the first Indian satellite which was placed in orbit by Indian launching vehicle, SLV–3 in 1980. Presently the organization is headed by Dr. A S Kiran Kumar.

Rotating Frame of Reference

In rotating frame of reference which is considered as a special case of non-inertial frame of reference rotating relative to an inertial frame of reference. In this case the frame of reference is accelerating with respect to an inertial frame just a boy is rotating a stone tied to a string.

INDIAN FOREST SERVICES : PAPER ANALYSIS (PHYSICS)


India is one of the First countries in the world to have stated scientific management of its forests.The Indian Forest Service, one of the three All India Services, was constituted in the year 1966 under the All India Services Act, 1951 by the Government of India.The main mandate of the service is the implementation of the National Forest Policy which envisages scientific management of forests and to exploit them on a sustained basis for primary timber products, among other things. Since 1935 the management of the forests remained in the hands of the Provincial Governments and even today the Forest Departments are managing the forests of the country under the respective State governments.
