UNIVERSE and YOU

MOON and TIDES of EARTHज्वार-भाटा और चाँद का इससे  सम्बन्ध  The mooon is the main reason why oceans have tides;the moon's gravity has stronger influence on the side of earth nearest to it, and it draws earth's water towards it ever so slightly ,which causes daily tides. May be you have noticed that tide runs higher during the FULL-MOON but it is not the moon's phase that causes that. the moon's tidle effects depend only on its mass and its distance from earth,which stay almost constant no matter its phase.                              So what makes high tides get even higher ?                             It is to do with the sun. The sun has also have gravitational pull on earth ,although a little less than half that of the moon.                          ...

BIGGEST TELESCOPE FROM NASA American space agency NASA has made largest telescope of the WORLD till now successfully. This gold mirror containing  "JAMES WEB SPACE TELESCOPE"(JWST) will research on the secrets of the BIRTH OF UNIVERSE.  It can find out the galaxies which were found after      BIG-BANG  and 13.5 billion  years ago from now. It is HUNDRED TIMES more powerful than the HUBBLE telescope. This  is the HUBBLE telescope which was launched  in 1990 and working continuously from then. Now JWST will be   kept at the place of HUBBLE telescope. NASA engineers were working from 20 years on this telescope. JAMES WEB SPACE TELESCOPE contains a 18 carat   GOLD PLATED MIRROR    of diameter 21 ft. "THERE ARE INFRARED CAMERAS OF FIVE LAYERED SUN SHIELD."     These sun shield layers are as thin as HUMAN HAIRS. CAMERAS are so muc...

Beautiful phenomenon based on surface tension Hello friends, here i'm going to tell you some  more  special and beautiful phenomenon based on surface tension. The first is............. 1.Formation of Lead Shots (MARBLES) For making marbles, we take the melted glass in liquid form. Now from a certain height melted glass is threw into  a big water tank as a fountain. During fall of glass liquid due to surface tension the melted glass acquire minimum surface area and turns into spherical marbles. Reaching to the water tank it converts into solid marbles. By this process the beautiful & colorful marbles  are formed,in case of big drops it is affected by gravity and it becomes some flat. NOW BEAUTIFUL  MARBLES ARE READY 2.Spraying results in coldness When we spray water on skin or on anyone then we feel coldness why?? do you know?? When we spray water then it converts into numerous small drops due to this the surface ar...

Surface Tension (you know???) water drops on glass surface when  a drop of water is placed on the surface of cleaned glass,then the water spread as a thin film on  glass surface. But when a drop of mercury is placed then it forms a small SPHERE. Similarly if there is greece on  glass surface then water drop will also form a tiny sphere.WHY????? mercury drop on glass surface Now the conclusion comes out that "the behavior of liquids is not affected only by the GRAVITATIONAL FORCE but there is another factor called surface tension. If a drop is of negligible weight then it has perfect spherical shape. For examples: rain drops, soap bubbles, etc. We should know that---------                                   "For a given volume a sphere has minimum surface area" Hence, it is the tendency of free surface to shrink to it's minimum surface area. How to define the ...

Water  vs  Temperature Hello, friends here i'm going to tell you, how the behavior of water changes with respect to temperature .            We have seen that every liquid expand in volume on heating  but there is another situation in case of water  because water has HYDROGEN BONDING  and have DIPOLE MOMENT. now,in the case of water, when water is heated from 0 to 4 degree Celsius it's  volume decreases  and after 4 degree Celsius it's volume start to increase.             Due to this phenomenon, in our every day life we can see the natural secrets.  Now using this phenomenon ,                                              i'm going to tell you a number of natural effects. Density of water                 ...

Floating of Ping-Pong Ball on  water jet & air jet The principal  behind floating of a ping -pong ball is based on  BERNOULLI'S THEOREM now i am  going to tell you the whole principal behind this phenomenon. pin-pong ball placing on air jet First to understand this phenomenon, we should to look upon BERNOULLI'S THEOREM BERNOULLI'S THEOREM        This theorem is like energy conservation principle.   "When a non-compressible and non-viscous Liquid or Gas flow like linear current motion, then  at any point of it's path the TOTAL ENERGY (sum of pressure energy, kinetic energy and potential energy) of liquid or gas  remains constant."                                      It is the BERNOULLI'S THEOREM now the the conclusion comes out that            "the side where the velocit...
