Energy Energy is the capacity to do work and is required for life processes. An energy resource is something that can produce heat, power life, move objects, or produce electricity. Matter that stores energy is called fuel.  Human energy consumption has grown steadily .throughout human history. Early humans had modest energy requirements, mostly food and fuel for fires to cook and keep warm. In today's society, humans consume as much as 110 times as much energy per person as early humans.   Most of the energy we use today comes from fossil fuels (stored solar energy).   But fossils fuels have a disadvantage in that they are non-renewable on a human time scale, and cause other potentially harmful effects on the environment.  In any event, the exploitation of all energy sources (with the possible exception of direct solar energy used for heating), ultimately rely on materials on planet Earth. First  questions we want to answer in this di...

THE UNIVERSE CONTAINS EVERYTHING that exists, from the tiniest subatomic particles to galactic superclusters (the largest structures known). No one knows how big the universe is, but astronomers estimate that it contains at least 125 billion galaxies, each comprising an average of 100 billion stars. The most widely accepted theory about the origin of the universe is the Big Bang theory, which states that the universe came into being in a huge explosion—the Big Bang—that took place between 10 and 20 billion years ago. The universe initially consisted of a very hot, dense fireball of expanding, cooling gas. After about one million years, the gas began to condense into localized clumps called protogalaxies. During the next five billion years, the protogalaxies continued condensing, forming galaxies in which stars were being born. Today, billions of years later, the universe as a whole is still expanding, although there are localized areas in which objects are held together by gravity; f...

Lecture i. A Candle: The Flame — Its Sources — Structure — Mobility — Brightness. I purpose, in return for the honour you do us by coming to see what are our proceedings here, to bring before you, in the course of these lectures, the Chemical History of a Candle. I have taken this subject on a former occasion; and were it left to my own will, I should prefer to repeat it almost every year — so abundant is the interest that attaches itself to the subject, so wonderful are the varieties of outlet which it offers into the various departments of philosophy. There is not a law under which any part of this universe is governed which does not come into play, and is touched upon in these phenomena. There is no better, there is no more open door by which you can enter into the study of natural philosophy, than by considering the physical phenomena of a candle. I trust, therefore, I shall not disappoint you in choosing this for my subject rather than any newer topic, which could not be be...

Recently I have realized that some viewers are thinking that I am posting some So-Non-Science post on my blog to grow my audience with an aim to click bait tricks. But that's not true. First of all, I am a passionate blogger posting about science, history, and some random stuff but ther e is no intention to monetize my blog. As a blogger somehow I, i really want the real reader and other blogger but not click baiter. I can't post daily because I need time to do deep research on the topic I am going to write. As a science blogger, I can't write the fake post just to increase traffics in my blog. As a Science guy, More specifically as a Physicist, I feel students and general mass really need a proper explanation of their syllabus topic. In a maximum country even in the USA education system is low quality. Students don't enjoy their study and syllabus. Even some students like History and some like science and so on. But everyone needs a general knowledge if they are born t...

As a physicist, I love to demonstrate physics in a fun way. Science is fun but you have to take it seriously. I have recently discovered a youtube channel named " ElectroBoom " that has demonstrated all electric phenomenon in a very fun and interesting way. Now as a small youtuber I can't demonstrate all the things just right now but I will try to upload in future. But that's not gonna be a be problem because I want to share the facts in this post. Have a read and have fun. In the world of quantum physics, a " glueball " is a particle that doesn't contain any matter and is made up of pure force. We, The Human also emit radiation .  Such radiation  is sometimes called thermal  radiation . Most of the  radiation emitted by the human  body is in the infrared region, mainly at the wavelength of 12 microns. Banana is Radioactive. They emit Ionized Radiation in a very small amount. The most radioactive place in earth is the average smoker's lungs. ...

Sometimes, I think it's probably better to share some cool random facts which are not a hoax. As a science guy, I assure you the following facts are true and you can check it on yourself. I have given some genuine source attached to the facts. Now let's jump into it. The hospital in which you where born is the only building you leave without entering. You are matter until you have been multiplied by the square of the speed of light in vacuum. E=MC 2 There is no Free energy. Many YouTube videos and blogs claim it but they are false. There are no such things that the government is hiding from us. (N.B. Ha Ha, Government is only honest in this energy case, rest of case is History :D) {Source} [ Or read Nikola Tesla's Original Book ] Education system tries to crush the curious mind by deploying a So-Called examination system for which Children and students don't enjoy Study or Education (In maximum case). All galaxies, regardless of how large or small they are, rot...

The Title is itself a question as the definition of Modern World where we depend much on Machines ( Laptop to Mobile, Artificial Intelligence to Smartphone app) and algorithm, the question arises. There can be two way to see the question. As we grow up, we start to lose the free time for the job and hence one theory is getting more value that this schedule might cause degradation of our relationships with friends, family, Relative, etc. When we were a child, we played, we studied and we intensely insisted our parents to buy some toys or children alike object for us. Some parents bought us and some didn't. We played in the ground more than this era's children who play in Smartphone or Pc. Gaming becomes virtual, So the taste we had by playing football in the ground full of clay in monsoon, has been lost in this Digital Era. Another problem children have today is they have more health problem than us. From pollution to Stress of study, they even don't enjoy their doing li...
