Do you know, Why ocean water is blue? Many of you may think that the answer is very simple. you may say that the blue color of sea water is due to the reflection of the sky, which is of blue color but it's not like that. So let's try to find out the real reason behind it. As we all know that water has no color. The water takes the color of what is mixed into it. So has anyone mixed the blue color into our oceans? Not actually. Then why the sea water looks blue? Actually, the blue color of sea water is due to the rays coming from the sun.

Why Are Some People Left Handed
Why are some people left-handed? Which hand would be the dominant hand is decided in the womb or after our birth? Does it has anything to do with our brain or the environment?
Do you know that around 10% of the people all over the world are left-handed and August 13 is celebrated as International Left Handers Day.
Why Are Some People Born Left Handed Video
Left-handed people are unique in themselves and there are some advantages and disadvantages of being left-handed. So let's now come to our main question, why some people are born left-handed.Why Are Some People Left Handed
The dominant hand-left or right hand has, in the past years, been a characteristic believed to be determined by a particular hemisphere of the brain. This was even before birth, but new research done in 2017 showed that hand dominance is instead associated with the spinal cord.
The study found that a baby's left- or right-handed tendency is already present and set in the womb, long before the baby's brain gains mastery over all movements in the body. The motor cortex in the brain controls all the hand and arm movements by sending signals down to the spinal cord, which interprets them into motion. However, at this time, the motor cortex in the brain and the spinal cord aren't yet connected until the 15th week of pregnancy. Interestingly, babies show hand preferences starting 13 weeks, sucking either the right or left thumb. This early behavior shows that the brain does not determine handedness since it is not connected to the spinal cord, at least not yet. It is in weeks 8 to 12 of pregnancy that scientists find variations in gene expression in the spinal cord between the arm-moving and leg-moving segments. These differences in expression make a person left-handed or right-handed. So, it is our spinal cord, not our brains!

String Theory for Dummies - String Theory - String Theory Explained
We will discuss here- What is string theory, what are strings in string theory and how small are these strings. We will also answer, Why string theory is so important and how it has proved promising in answering the deepest questions in fundamental physics.
What are Strings in String Theory
Before the introduction of string theory, it was considered that the fundamental particles of the nature are point like particles. But according to string theory it is not true. String theory says that these fundamental particles are extremely small one dimensional objects known as strings. So strings are the smallest thing in the whole universe as everything, even the subatomic particles are made up of these one dimensional objects called strings. Graviton is a quantum mechanical particle that carries gravitational force. In string theory one of the many vibrational states of the string corresponds to the graviton.String Theory Explained Video
What is String Theory
String theory deals with how these strings propagate through space and how do they interact with each other. According to the string theory all fundamental particles are actually tiny vibrating loops of string. Various properties of particles like mass and charge are determined by the vibrations of the one dimensional string like entities. According to researchers, the size of the string is about 10^-33 cm.Why String Theory is Important?
Scientists hope that string theory will help in answering deepest questions related to fundamental physics. String theory has been applied to unravel mysteries of early Universe cosmology, black holes, nuclear physics and condensed matter physics. Quantum gravity is one of the deepest problems in modern physics. All the fundamental forces except gravity are described within the framework of quantum mechanics. As Albert Einstein described gravity using the general theory of relativity but the general theory of relativity is formulated within the framework of classical physics. According to Einstein's general theory of relativity, gravity is the distortion of space-time caused by the presence of matter. So a quantum theory of gravity was needed in order to reconcile general relativity with the principle of quantum mechanics. String theory can help us here. Actually string theory potentially provides a unified description of gravity and particle physics. It is a self contained mathematical model that describes all fundamental forces and forms of matter. So we can say that string theory is a candidate for a theory of everything. Now let’s get an idea about how small are the strings in string theory.Size of Strings in String Theory
Actually a string is of the order of 10^-33. This number is so small that just by staring at this number you won’t get the idea. So let me make it simple for you with an analogy. Let’s assume an atom were magnified, to the size of the whole observable Universe, then a String would be the size of a tree!!! Now let me do one more comparison to make it more clear. This time I'll compare the size of an electron with the size of a string. So, if we increase the size of an electron equal to the size of the Earth, then a string would not be bigger than just a 3 storey building.What Causes Fear and How to Overcome Fear in Life
What is the Purpose of Fear and why it is Necessary
There would hardly be anyone in this world who never got scared. Actually fear is the body's defense mechanism. It is the fear that keeps us in discipline and prevents us from doing wrong things. If we are not afraid of anything, then we may harm ourselves or others. Like a child is not afraid of anything. He is not afraid of heights or any creature. So we have to take care of him all the time. But as the child grows up, he also starts to feel fear.
What is Fear and how to get rid of it Video
Is the Fear Real (An Unknown Fear)
But what happens when an unknown fear always haunts you. It is important to note here that in most cases our fear is not real, it’s imaginary. You might have heard that people suffer from different types of phobias. Some are afraid of lonely places, some are afraid of crowd and some find it very difficult to face water or heights. There are thousands of kinds of phobias that people are suffering. Friends, to solve any problem, one must first know the reason for it. It means if we get to know the cause of our fear, then it will be very easy to overcome it. So here I will tell you the two root causes of fear. After knowing them you can easily overcome your fear instantly.What Causes Fear
Two root causes of fear are-1. Not living in the present moment
2. Your desires and attachments
1. Not living in the present moment
Whenever you feel scared, you are either afraid of thinking about the future or whatever has happened to you in the past. So fear is always in the past or future. In the present moment, there is only life, No Fear !!! Let me explain it with the help of an example. Even if you are fighting with someone, you will not be afraid. Because at that time your full focus will be on fighting. But as soon as you shift your focus from present moment to past or future and start thinking, you feel scared. You may think, what will happen to my family, what will happen to my children, if I got hurt or die in the fight. In this way, as soon as your attention is removed from your present task which is fighting, your mind gets filled with worries and fears. And when this happens, your focus is not on fighting and your chances of losing the battle are increased. Thus, only by living in the present moment, our fear is gone.
Now I will tell you about the second cause of fear.
2. Your desires and attachments
No matter what kind of fear you have, it is the result of your desires in some form or the other. If you have desire to live, then there will definitely be the fear of death.
Most people will agree that the biggest fear is the fear of death. You must have seen that the person who is not afraid of dying, has nothing to lose and has no desires, can not be frightened by anything. Only a single thought that whatever is happening is temporary and one day we are going to die, will reduce your fear to a great extent. When you feel afraid, you need to notice that you must be clinging or attached to some person or object. We do not want to leave that thing or person under any circumstances. And this attachment causes our fear. If you could remove yourself from these attachments and desires somehow, you will find that you have overcome your fear at that moment.
So we have seen that if we have to overcome any kind of fear, then we have to take care of only two things. The first is to practice living only and only in the present moment without worrying about the past and future. And second, whenever you are afraid, pay attention what desires and attachments are causing it. You will get your answer.
