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 Trees are Painted White and Red
Do you know that there are many scientific reasons behind this?
Here I'll tell you 3 scientific reasons for doing this.
So let's start.
Why trees are painted white and red Video
First Reason of why trees are painted white and red
The first reason for coloring trees in white or red stripes is to make them stronger. You must have noticed cracks on the trees and many times they get infected by insects.Second reason of why trees are painted white and red
Another important reason behind coloring trees with white or red color is their safety. Coloring the trees ensures that these trees are under the protection and supervision of the forest department. For this reason they cannot be cut. In this way, security of the trees along the highway is ensured.Third reason of why trees are painted white and red
Now we will discuss third and the last important scientific reason behind coloring trees. Actually, when the trees along the highway are painted white or red, they can be seen from a distance. It reduces the possibility of accidents caused by hitting trees. The white color in particular provides protection from accidents at night. So, there are many scientific reasons behind coloring trees in white or red.13 Mar 2021

Why Are Some People Left Handed - Why Are Some People Born Left Handed
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
It was previously believed that the left or right hemisphere of our brain is responsible for determining the dominant hand even before we are born. But later in a study done in 2017 it was found that it has nothing to do with the brain. Actually answer to this lies in our spinal cord. According to the research, before the brain starts controlling the body movement, it is determined in the womb whether the child would be left-handed or right-handed. Let's now understand how it happens. There is an area called motor cortex in the brain which controls arm and hand movements. This motor cortex sends Signal to the spinal cord and the signal is translated into a motion. Here it is to be noted that the motor cortex of brain and the spinal cord are not connected up until about 15 weeks of pregnancy. But the baby starts to show signals of dominant hand in the womb before 15 weeks of pregnancy. It has been observed that babies tend to suck either their right or left thumb from week 13 in the womb. It clearly indicates that the brain is not responsible for deciding left handedness or right handedness as it is not connected to the spinal cord up until 15 weeks of pregnancy. It means, the spinal cord decides the hand preference. During a study a team analyzed the gene expression in the spinal cord. The study was conducted during the 8th 12th week of pregnancy. It was found that there was significant difference between left and right handedness in the segments of the spinal cord which is responsible for controlling arm and leg movement. So it is the difference in gene expressions in the spinal cord not the brain that makes a person lefty or righty. Friends now you know why some people are left-handed.

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 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
