**Description:**

Maths and science & technology Proficiency in Mathematics is always considered to be important in engineering. One does not know where suddenly one finds the need of mathematics till one is pushed to a corner. Earlier, students of agriculture were not very much bothered about mathematics. yet there is no research without application of mathematics in one form or another. How does one know whether a particular treatment is useful to get better cotton, jute, silk or even artificial fibres? First we have to know what is a good cotton. One studies all the physical properties such as fibre-length, strength, ability to form strong threads and so on. Changes due to various treatments have to be significant statistically. The minimum number of experiments that are needed to determine a particular property – even energy levels of atoms, the wavelengths of the various lines of spectra, the calculation of energy levels are all determined by statistics. To determine the structure of molecules or crystals, group theory is the main tool. There are no hard-bound barriers dividing any two branches in science. To study in a systematic manner, we divide it into Maths, Physics, Chemistry, agriculture or Industrial research. ‘Science

is a single field’.
