Universe is big is a well-known fact. But when it comes to being big, how big? How is it measured? It is big with reference to what? Is universe really infinite? There should always be a reference point which helps infer how big our universe is. If our universe is infinite then why is it termed as big? Scientists have proposed that universe is expanding. The size of universe includes the number of elements existed in that and their sizes. The distances between objects in space are way beyond your imagination. The reference with which the universe is measured is

Gravity is the king of all forces. It has a big role in the creation of this universe. Sir Issac Newton is the first thing we remember when we talk about gravity. Newton has done immense contribution to the world by discovering about gravity and gravitational force. Most of the forces or scientific calculations are all being done based on gravitational force. Have you ever imagined how the world would be without gravity? The gravity is the power holding all the creatures in this world. How would plants grow? How would you do your daily activities? It feels like life

Minerals deposits are found in the deep earth crust. Ages ago people could find the minerals in the upper layers of earth. But the minerals so found were less in quantity. That is when the ancient humans came to know that minerals are found underground. So when there was more and more requirement for the minerals, people started digging the ground to find it. The ore genesis theory explains the process of formation of minerals underground. Source, transport and trap are the three main components of ore genesis. These three factors determine the amount of deposition. The large source, efficient

Technology has been advancing so tremendously day by day. Driver less cars are one of the latest advancements in transport sector. You would be wondering how the car will operate? Is it really possible? Well, yes it is possible. There is a lot of technology involved in it. This driver less cars are popularly known as Google cars. Well, any new product to market has both positive and negative feedbacks. Some people feel it will be a great help in future. But contradictorily others also say that such technology makes people more dependent. Yes, both the arguments are true. From

There are so many fascinating facts about moon that leaves you awestruck. Have you ever wondered how moon was formed? How would it be in the moon? The thoughts about moon is just amazing. Moon is a sign of calm and peaceful nature. Did you know? There are four kinds of lunar months: The lunar months are dependent on the phases of life. So there are four lunar months. Anomalistic month: The orientation of moon is not fixed. It is more elliptical. Satellite of earth is placed at a distance. The least distance between earth and satellites including moon is

Yes, the speed of the vehicle affects the consumption of fuel. The main reason behind this is air resistance or air drag. What is this air drag? When you are out for a ride on a cool breezy day, you feel the force of air hitting you in the opposite direction. We can feel the wind in the air around us. Air resistance and air friction are the consequences of this air flow. There is opposition air friction force experience while driving a car. This force is called air drag or air resistance. The car’s motion in turn helps to

Imagine that you were able to walk through a wall, what would you call yourself? A Ghost? A Magician? Now, it may sound absurd for this to be true, but in quantum physics this is something quite close to being true. But, if we were to dig deeper, these studies have helped ius understand something much more than magic, bringing us closer to our fantasies, but also rationalising it.                                 Born at Oranienberg near Berlin on January 8, 1891 Walter Bothe was not only a renowned nuclear physicist, but also an accomplished musician and a painter.
