Methods for drug discovery Forward approach and Reverse approach are the two widely used methods lying under the drug-discovery process. The final steps (testing) for both are similar, the only difference is that Reverse Approach establishes the target site for
There are broadly seven ways in which a substance interacts with the electromagnetic spectrum: – Absorption, Reflection, Refraction, Diffraction, Photoelectric Effect, Scattering, and Radiation. There are two types of radiations:- Due to temperature Due to a chemical reaction (includes nuclear radiation)
Introduction General theory of relativity (GTR) describes gravity as a geometric property of space-time fabric. It combines specific relativity and Newton’s law of gravitation. GTR which accounts for gravity and all of the things it dominates: orbiting planets, colliding galaxies,
All the factors mentioned in the above video are of course the preliminaries. What we want to understand, is if all these factors were removed, and the economy was allowed a free flow, will there still be inflation? Answer: Yes.
TL;DR High molecular structural symmetry and lower wave scattering properties are why metals are good conductors. Your life is a lie Movement of delocalized electrons has little to do with conduction of heat How do we know that? Think about
Have you ever noticed that almost every other animal group has a plethora of species; goats, cats, dogs, cows and a million more families with a million more species under them? This however, isn’t the case with us human beings.
How do we measure time? Why do we measure time? What is the basis for measuring time? Who set the rules? Why is a second as long as it is? Who/what keeps this exact measurement of the second? Answers ahead!
Why is glass transparent of all objects? Why is glass used in a mirror, instead of any other object? Why haven’t these questions struck me before? Well the third question I can’t answer, but the other two I will. First
Cancer Basics From the day you were conceived, your body has been busy dividing its cells rapidly and today you are comprised of 37 trillion cells of different form and function. With 3 billion nucleotide bases to copy for each
TL;DR – Matter is seen as a result of energy field interactions in the Universe and in order to get rid of matter, fields need to stop existing first. If someone would ask you to describe matter, you’d probably say
“The vacuum is one of the places where our knowledge fizzles out and we’re left with all sorts of crazy-sounding ideas,” says John Baez, a mathematical physicist at the University of California at Riverside. Electricity means the flow of
As a measure, irrationality is irrelevant. When I originally wrote this article, I wanted to somehow prove that irrationality does not exist naturally, that the only way we can possibly create an irrational number is by assuming that infinity exists.
If you’re wondering how you’re unable to wake up on your own in the morning (even after your alarms ring fifteen times), then you’re in the right place. How does the body measure time? The body doesn’t measure time as
Why there is an asteroid belt between Mars and Jupiter, and not a planet? In 1596, Johannes Kepler predicted, “Between Mars and Jupiter, I place a planet” in his book, Mysterium Cosmographicum. Later, the astronomer Johann Daniel Titius of Wittenberg
Light perception extends far beyond just vision. Light is an amalgam of other components apart from the visible spectrum. Heat sensation is possible due to light’s presence, body’s Vitamin D synthesis relies entirely on the UV rays, light sets a morning alarm
Why do we need to iron our clothes? Why does a paper get crumpled? Why do our fingers get wrinkled when kept in water for long? What is a crease? How is it different from a fold? Why do some
Mobile phones are the symbol of Information Age. They have bought our world closer and have put a vast array of data in the palm of our hands. This is all possible by the use of electromagnetic waves ( radio
For ageing parents, wayward and intractable children may be an obvious reason for gray hair. However, scientifically the questions as to why old age cause hair to turn gray still isn’t very well understood. Let’s start with the basics. Some
Turtles travel thousands of miles back across the sea just to lay eggs in the same sand?! Not only Turtles, many other animals and birds like Homing Pigeons, Fruit flies, many Mammals, even certain Bacteria and Molluscs have these awesome
Have you noticed that while most grass, bushes, trees and such are green – there are a few that didn’t get the memo? Red and purple plants are not uncommon but can still be rare. So, comes the question –
TL;DR Yes, energy can produce matter by colliding way too many photons together to produce matter-antimatter pairs. The Mass-Energy Equivalence The Mass-Energy equivalence suggests the mass of a stationary body has some internal or intrinsic energy, called its rest energy. For
Introduction So, you know what I am talking about: the time when you are just about to fall blissfully asleep and you suddenly feel like you’re falling as if someone threw you off a tree! According to scientists there are
Electrostatic Forces The dust sticks to fans for the same reason that paper clippings stick to your ruler after you’ve rubbed it really hard against your hair: electrostatics. In a similar manner, the frictional forces between the fan blades and air
The rule of three is a writing principle that suggests that things that come in threes are inherently funnier, more satisfying, or more effective than other numbers or things. Stated as ‘omne trium perfectum’ in Latin, this rule has been
If you’ve ever seen a nature documentary you’ve probably noticed how new-born babies of most animals can walk and live (mostly) independent of any caregiver; humans on the other hand need a bit more help. Ever since the comparisons between
Introduction Sleep made our ancestors vulnerable to attacks by wild animals. Sleep is what makes ‘Nobita’ stand outside his class. Despite such potential risks involved, we along with almost all other organisms in the world waste one-third of our lives
What we were taught Remember the science teachers saying sunlight is white? Is it though? Is the Sun yellow? What is even “colour”? Why do we perceive different frequencies of the electromagnetic spectrum as different colours? To be honest, no
As summer sets in all we can think about is a nice cold refreshing shower and some cold sweet drink with a fancy straw. This ethereal combination is however a positive feedback loop of even more suffering. How? Let’s start
Bullet train The bullet train isn’t a train at all. It doesn’t have an engine or wheels or a steering. It works on the principle of magnetic levitation(maglev) and magnetically guided steering. It runs at 330 Km/H, and was developed
Second Price Auction A general second price auction or a GSP is a type of auction where the bidder has to pay the price bid by the next best bidder. For example, if you bid 10 rupees for an apple,
1) “Stars in daylight” If you have never gotten punched in the face by someone, I’ll tell you another easy way to see stars in the sunlight. Close your eyes and press over them a bit hard for a while;
Why is it that when the room temperature is 37°C we feel hot instead of feeling neither hot nor cold, since it is also our body temperature? The answer, in fact, lies in the way our body functions. The human
Our science books never told us about the 4th state of matter. We didn’t know this but it exists as an integral part of our everyday life, and that’s why we need to know about it. Another state of matter?
Music can be called the seed of evolution of portable storage. People wanted to store music which lead them to develop portable storage. In other words, man’s love for music made him invent it. Hence proved that music is by
