## Nuclear Fission Basics

Nuclear fission is said to have occurred when nucleus of an atom splits into several small fragments. In nuclear physics nuclear fission either occurs as a nuclear reaction or as a radioactive decay process in which nucleus of an atom splits into smaller and lighter nuclei. The fission process often produces free neutrons and photons (in the form of gamma rays), and releases a very large amount of energy even by the energetic standards of radioactive decay.

## Vector Differentiation full length notes

Full notes on vector Differentiation is now available at the website physicscatalyst.com covering following topics
1. Differentiation of vectors
2. Scalar and vector fields
3. Gradient of a scalar field

## Vector Differentiation part 2

In this post we’ll discuss about Divergence and curl of vector fields. Here get a short synopsis of what is divergence and curl of a vector field along with their geometrical interpretation.

## Scalar and vector fields

We know that many physical quantities like temperature, electric or gravitational field etc. have different values at different points in space for example electric field of a point charge is large near the charge and it decreases as we go farther away from the charge. So we can say that electric field here is the physical quantity that varies from point to in space and it can be expressed as a continuous function of position of point in that region of space .
