A vector field  vector F is said to be irrotational vector if curl of F is equal to zero ▽ x F  =0 Irrotational Vector field Concept The Above phenomenon is due to Irrotational vector Field.   Explanation Of above picture:  Side wheels indicated as red arrow and white arrow are rotating in the direction of Anti-Clockwise and Clockwise respectively Red arrow- (Wheel)->Anticlockwise White arrow-(wheel)-> Clockwise Why Middle wheel does not rotate? Answer: Middle wheel does not rotates because the flow of water to the surface of wheel does not allow to move. Why does side wheels rotate? Answer: Because at the side of river the speed of flow of water is very low as compared to in the center of the river.

Our sun and the nearby stars are all parts of a vast collection of stars called the MILKEY WAY GALAXY. For a long time it was thought that this was the whole UNIVERSE . In 1924 that the American Astronomer Edwin Hubble demonstrated that ours was not the only galaxy. There were, in fact many others,with vast tracks of empty space between. In order to prove this he need to determine the distance between to thses other galaxies. 1.DETERMINATION OF STARS : We can determine the distance of nearby stars by observing how they change position as the Earth goes around the sun. But other galaxies are so far away that, unlike nearby stars, they really do appear fixed. Hubble was forced,therefore, to use indirect methods to measure the distances. 2.Factors On which the brightness of Stars depends: i.)LUMINOSITY ii.)How FAR IT is For nearby stars we can measures both their apparent brightness and their distances, so we can work out their luminosity. Finally some i...
