Science is advancing at a good pace even in these tough times in which the world is hardly hit by COVID – 19. Here are some science news worth listing on the basis of advances made in July 2020. Science News Monthly – July 2020 COVID 19 Vaccine Enters Final Phase At the moment, the whole world is searching for COVID 19 vaccine. Any news regarding vaccine can eliminate the fear and anxiety that people are suffering from, due to this pandemic. Two noteworthy achievements took place in July. Oxford’s Vaccine at the Final phase A vaccine developed by the…

The billion-dollar experiments at LHC has always bestowed us with remarkable new discoveries like God particle, the Higgs Boson and several other particles that make our mysterious Universe. Discovery of Tetraquark was another milestone for LHC. Quark Quarks are the fundamental particles which are not found in the free state but are responsible for making almost the entire Universe. The standard model predicts, the matter Universe is made up of quarks and leptons. There are six flavours of quarks – up, down, charm, strange, top and bottom. They can combine in the combination of two or three or four or…

Physics delivers the facts, facts that are logical and can be explained with pure mathematical logic, 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  These facts listed here are not in order of any factors, they are just from random topics of physics. 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 a concept…

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…
