Beautiful World of Physics

We cannot define anything precisely! If we attempt to, we get into that paralysis of thought that comes to philosophers, who sit opposite each other, one saying to the other, ‘You don’t know what you are talking about!’ The second one says ‘What do you mean by know? What do you mean by talking? What do you mean by you?’, and so on.

Einstein & Gravitational Waves.....The Genius

What is a gravitational wave? A gravitational wave is an invisible (yet incredibly fast) ripple in space. We’ve known about gravitational waves for a long time. More than 100 years ago, a great scientist named Albert Einstein came up with many ideas about gravity and space. Albert Einstein, official 1921 Nobel Prize in Physics photograph. Einstein predicted that something special happens when two bodies—such as planets or stars—orbit each other. He believed that this kind of movement could cause ripples in space. These ripples would spread out like the ripples in a pond when a stone is tossed in. Scientists call these ripples of space gravitational waves . Gravitational waves are invisible. However, they are incredibly fast. They travel at the speed of light (186,000 miles per second). Gravitational waves squeeze and stretch anything in their path as they pass by. What causes gravitational waves? The...

The Dangerous Ratio

The Dangerous Ratio It's a stormy day on the sea off the coast of Greece. The date is around 520 BC. Fighting for his life, a man is heaved over the side of a boat and dropped into the open water to die. His name is Hippasus of Metapontum. His crime? Telling the world a mathematical secret. The secret of the dangerous ratio. The murder of Hippasus is a matter of legend, but the secret was real, and certainly dangerous enough to the beliefs of those who knew about it. It was a secret owned by the school of Pythagoras. These early Greek mathematicians (Pythagoras himself was born around 569 BC ) were obsessed with the significance of whole numbers and their ratios. The Pythagorean's motto, carved above the entrance of the school, was " All is number". The inner circle of the school, the mathematikoi, believed that the universe was built around the whole numbers. Each number from one to ten was given a very special significance. Odd numbers were thought to...

Love Story of Physics & Maths

Love Story of Physics & Maths Some people ask the question:- What is the relationship between math and physics? Well, sometimes Math leads. Sometimes Physics leads. Sometimes they come together because, of course, there’s a use for the mathematics. For example, in the 1600s Isaac Newton asked a simple question: If an apple falls then does the moon also fall? That is perhaps one of the greatest questions ever asked by a member of Homo sapiens since If an apple falls, does the moon also fall? Isaac Newton said yes, the moon falls because of the Inverse Square Law like an apple. He had a unified theory of the heavens, but he didn't have the mathematics to solve the falling moon problem. So what did he do? He invented calculus . Generally, modern calculus is considered to have been developed in the 17th century by Isaac Newton and Leibniz So calculus is a direct consequence of solving the falling moon problem. In fact, when you learn calculus for the fi...
