WELCOME TO THE WORLD OF MOST FASCINATING PHYSICS

    Ever since our ancestors sharpened sticks and shaved flints around the  campfire, humans have been tool makers. Today, engineers apply this  maker's impulse to the realm of nanotechnology. Nano-engineers understand that bulk materials  have  defects  and  imperfections  that weaken their overall  structure.  As  we  shrink  objects to the nano- scale, the presence of defects is greatly reduced thus it makes nano- materials stronger than their large-scale counterparts. One of the  most wonderful and interesting initiatives is to turn water into a  sort of nano-tech battery to store solar energy.       Nano-materials are also chemically more reactive than their macro-scale equivalents. That’s because catalytic chemical reactions occur when molecules meet surfaces in an energetic state with more surface area translates to more reactions. So breaking a bulk catalyst down into billions of nanoparticles provides a vastly greater active surface area. This is not merely a theoretical c

      Is it really possible for human beings to do time travel at the speed of light? This is a very mysterious question for all the scientists and physicists till today.     During our childhood, we were really amazed and wondered how Superman could travel faster than a bullet speed. We could even see him, chasing down a thief at a speed of a bullet or a projectile fired from a weapon, his right arm would be outstretched and his cape rippling behind him. Imagine if he traveled at half the bullet's speed, the rate at the speed at which the bullet moved away from him would be halved. If he did indeed travel faster than the speed of a bullet, then he would definitely overtake it and lead the way. In other words, Superman's aerial antics have obeyed Newton's views of space and time: that the positions and motions of objects in space should all be measured relative to an absolute, non-moving frame of reference.                  During the beginning of the 20th century, all the
