The Sun is a massive star in the solar system, around which all the planets and heavenly bodies revolve. This spherically shaped body helps to hold the solar system together. It is a ball of hydrogen gas and plasma that emits its light and energy to all planets in the solar system, including the Earth. Interesting Facts about the Sun It’s believed to be more than 4.603 billion years old and has a radius of 696,340 km. Although we see or feel the sun on a daily basis, we don’t know all the amazing facts about it. So here are…

Physics delivers the facts; facts that are logical, unbiased, and without being agitated by our personal prejudice. Some of these facts are so amazing that we thought of listing them in our list of amazing physics facts. 10 Amazing Physics Facts  The facts listed here are not in order of any factors. 1. More You Run, More Mass You Gain People usually run so that they can lose excess mass and be fit but wait what physics has to say. According to the concept of variation of mass with speed, the more you speed, the more mass you gain. It…

If you believe common sense and logic can explain anything, that’s not how everything is. This realization beyond common sense and logic is the central mystery of quantum mechanics and it can be well explained by an experiment called the double slit experiment or two slit experiment. What is a double slit experiment? A double slit experiment is an interference experiment. Interference is redistribution of energy that occurs when two similar (coherent, frequency and wavelength same) waves are projected on a screen. This redistribution of energy (intensity) results alternative bright (maximum intensity) and dark (minimum intensity) patterns on the screen.…

People can make a clear distinction between men’s and women’s wear by just looking at the shirt buttons. Men’s shirt has a button on the right side while women’s shirt has a button on left. Why is it so? There are various reasons according to a different perspective. Reason for Men and Women Having Shirt Buttons on Different Sides Buttons have a long history as much as of 5,000 years. But the earliest of modern buttons were found on Germany dating back to the 13th century. On reference to that time, there can be various theories on this shirt button…

Blackhole is one of the greatest marvels of the Universe. It is not just literally black but the lack of its understanding makes it even blacker. It is the blackest thing in the Universe that has been encountered by a human being. As its name suggests, the black hole is a black body in the Universe. It is black because even light cannot escape from it. Light has a speed of 300,000 Kilometres per second and even with that speed, light cannot escape from it. History The concept of a black object which forbids light to escape from it was…

When it comes to powering vehicles with electricity, charging time is the main problem because it takes to long to get charged. Recent developments on supercapacitor technology have opened up this possibility. We cannot imagine our life without electronics, they have been part of our lives. I, miss my phone while I charge it. Though there are power banks which allow us to use them simultaneously while charging, it may not work for massive electronic devices. Let us think about an electric vehicle, the best of these vehicles take hours to get fully charged in the present situation. They would…

When things come to the quantum world, common sense does not work at all. One thing that bolsters the above statement is superfluid helium-4. It has properties that are completely absurd and does not make sense at all. Superfluid Helium-4 Superfluid helium-4 is the liquid state of helium-4, isotopic helium with 2 neutrons and 2 protons, at a temperature below 2.18 Kelvin (more than 270-degree centigrade below zero) and normal pressure. We know that any substance liquefies and finally solidifies on cooling. Helium-4 also liquefies on cooling. But, when we cool helium-4 to a temperature below 2.18 Kelvin, its atom…

Owls are amazing birds. Along with a good vision at night and 360-degree vision, did you know that they have the ability to fly without making any noise which makes them best birds of prey in the dark? Let’s dig deeper. Silent Flight of Owl Explained Bird’s flight have inspired a lot of techniques of flight, it had played a vital role in the development of air crafts. Owls flight we can learn some more, beyond flight. Owls are nocturnal birds, they hunt in the dark. We know the night atmosphere, it is quiet. Hunting at night is a strenuous…

We are made up of atoms which are 99.99% empty space. That makes us the same but isn’t it absurd that we don’t see through ourselves even though we are almost empty spaces? We are 99.99% empty spaces Atom makes up almost everything, we are also made up of atoms. It may sound preposterous that the thing that makes up everything is 99.99% empty space but it is a fact. In 1909, Ernest Rutherford’s team at the University of Manchester worked on an experiment in which they projected alpha particles (positively charged particles/helium nuclei) on a gold foil. Almost every…

An atom is a fundamental building block of matter. We see a picture of the atom in books and you might have drawn an atom during your school years. Does an atom look just round like that? The Actual Picture Of an Atom We are a being who wants to visualize everything. We want to see light in terms of rays or even abstract quantities like love in terms of behaviors. Maybe visualization assures the existence of something in my view. Yes, the very essence of the existence of something is its visualization. This is why the concepts of atoms…
