stars life .. how they are formed ... supernova , what is black hole, worm hole ..... very very interesting topic in very simple language and many images that make u understand easily

Neutron star ,an interesting part of astronomy. sobur hossain
A small work about neutron star which will make you interest in astrophysics ,a fascinating things on this earth.Moreover you will learn some facts about astronomy.

This is the presentation I gave when defending my Ph.D thesis at SLAC. The title of my defense was "Neutron Star Powered Nebulae: a New View on Pulsar Wind Nebulae with the Fermi Gamma-ray Space Telescope".
search on NASA site also go through the latest news related to black holes before presenting your seminar.
many queries are asked related to black holes.
present the astronomical data's for Good delivery of seminar.In the 18th century John Michell and Pierre-Simon Laplace first mentioned about the objects with a huge gravitation, from which even light cannot escape.
In 1915 Albert Einstein developed the theory of general relativity.
Karl Schwarzschild finds black holes as a solution to Einstein’s equations (1916)
Robert Oppenheimer and Hartland Snyder predict that massive stars can collapse into black holes (1939)
A black hole is a region of space that has so much mass concentrated in it that there is no way for a nearby object to escape its gravitational pull.”
Black holes are exotic structures whose gravitational fields are so powerful that they trap everything, even light. They were first postulated by Albert Einstein's theory of general relativity.”
This can happen when a star is dying.
Though they are black they are invisible to us.
The density of a black hole is so great it would be like taking the whole Earth and crushing into a volume smaller than a 1” marble!.
Stellar-mass: 3 to 20 times the mass of our Sun
Supermassive: Black holes with millions to billions of times the mass of our Sun
Mid-mass: In between stellar-mass and supermassive.
The Stars And The Galaxies In The Universe 2 Lguest2dc5cb
This powerpoint slidesare from form 3 sallabus and it is about stars and galaxies. Students are allowed to view and upload their ideas of stars and galaxies.

What is the purpose of the Sabbath Law in the Torah. It is interesting to compare how the context of the law shifts from Exodus to Deuteronomy. Who gets to rest, and why?

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
