Science is one of the marvels of the human mind. The human mind is always curious to know more about nature and the world and how everything works and fits with other things in the world.
It is believed that in the very early days of the evolution of human beings, the early humans knew little about the world and were trying very hard to create fire by rubbing two stones together. Today, it is not only possible to light a fire using better methods, other important things can be done by using machines and the use of technology.

Human beings used to look at the distant stars and wonder about the world beyond our own planet. Little was known that a few years later, people would not only understand how the universe works and what major forces control it but also be able to set foot on other worlds and moons.
The study of nature using straightforward mathematical equations, laws, and theories, and rational thinking is known as science, and today, it is an important field of study and research.
Science has been divided into further areas like physics, chemistry, and biology for better understanding and detailed studies and topics like gas chromatography, gravity, mechanics come under the study of things in physical sciences.
Chemistry deals with the study of smaller units of matter that make up the world like atoms and molecules and tries to understand the way that matter forms, how chemical bonds are created, and why some molecules behave differently than other molecules.
Biology is one of the most applied fields of science in the world as it finds its uses in the study and understanding of the human body. That is not all there is to biology, people who study and understand this field also understand the working of the physical bodies of other organisms like plants and animals.

Amazing Facts that Science has taught us
After years of studies and research, people have come to know a lot about the world and themselves through scientific studies. Some amazing things that science has taught us are:
The human race along with other living and non-living things exists on a spherical planet and it revolves around the sun which is a star just like a billion other stars in the whole universe.
The sun is about 5 billion years old and will live for another five billion years. It is a main-sequence star which is a particular phase in the life cycle of major stars in the universe, just like adulthood in human beings.
There are more neurons in the human mind than the number of stars in our galaxy, the milky way.
When something is dissolved, it happens by mixing things physically and not chemically. The chemical mixing processes are very different and generate other compounds and elements.
To separate mixtures, various techniques like evaporation, boiling, or gas chromatography are used. Evaporation is also the process by which fresh water is obtained through rains and moisture in the atmosphere from the salty seawater.
The basic unit of life functions of our body is a cell. Our body is a complex organization of various cells while some other organisms are only a group of two or three cells, sometimes even unicellular. These organisms are not very highly developed.
The human DNA matches with a chimpanzee the most which prove that humans are very close to chimps in terms of evolution.
Some scientists also suggest that some parts of our DNA are very alien and not seen in any other organisms. They also believe that this may mean that our life did not necessarily begin on earth itself and otherworldly beings may have something to do with it.
The existence of aliens is still not completely known or understood by us. Many people believe they exist while many dismiss the possibility of it. In spite of this, there have been UFO sightings across the world which none of us have been able to explain.
Apart from planets and moons, different types of rocks also revolve around the sun. one of these types of rocks are comets, which are made up of frozen gases, ice, hydrocarbons, and dust.

Many scientists believe that comets were the initial carriers of life and water to the planet earth because they carry hydrocarbons and water.
For any celestial object to be called a planet, it needs to follow certain rules. Pluto is not regarded as a planet anymore because it breaks some rules. Pluto’s orbit cuts the orbit of Neptune. This is a rule break as a planet must revolve on a unique orbit.
