When we hear the word science, many things come to our minds, such as a large textbook with thousands of pages, a lab coat, scientists, microscopes, an astronomer in space, aircraft, telescopes, and equations of Einstein, bubbling solutions in beakers, and many more. Science is a system of knowledge related to the physical, biological, and chemical world and its various phenomena.
Science is a vast subject, a body of knowledge and a process in which we can learn new things every day with new discoveries along the way. Not every fact is proven, but there is some data to support the theories and processes behind them. We can say that, in a way, knowledge and process depend on each other since, behind every knowledge, we need to prove the questions and answers related to them.
Aristotle: He was the first scientist who pioneered the techniques of logic, observation, inquiry, and demonstration in Greece in the fourth century BC.
In the late 3000 BCE, the ancient Egyptians discovered a decimal numbering system. They contributed their knowledge of geometry to solving practical problems such as the 3-4-5 right-angle triangle, and other rules were used to build rectilinear structures and lintel architecture of Egypt.
An official calendar was developed that contained twelve months, thirty days each, and five days at the end of the year.
Science is divided into three branches based on the interest and subject of study.
This branch studies the inorganic world and comprises the fields of Astronomy, Physics, Chemistry, and the Earth sciences.It is the branch of science that deals with inorganic materials. Physical science includes Physics, Astronomy, and Chemistry.
The occupations included in physical science are as follows:
Physicist, Quantum Physicist, Chemist, Astronomer, Cosmologist, and Computer Scientist.
This branch of Science includes subjects such as biology and medicine. Studying the organic world of life and its processes. It can help people understand the world, including plants, animals, and human biology.
The occupations included in biological science are as follows:
Marine Biologist, Pharmacologist, Forensic Scientist, Agricultural Scientist, and Virologist.
It is a field of natural science that deals with the earth's materials and its atmosphere.
The occupations included in this field are as follows:
Meteorologists, Land Planners, Oceanographers, Geologists, Palaeontologists, and Environmental scientists
Here are some of the amazing science facts which we happen to see in our daily life:
The stomach can dissolve heavy metals: Did you know that the human body is more capable than you think? Acids are ranked on a scale from 0 to 14; the lower the pH level, the stronger the acid. Human stomach acid typically ranges from 1.0 to 2.0, which means it has an incredibly strong pH. A study found that the thickened back of a single-edged blade dissolved after two hours of immersion in stomach acid.
A cloud can weigh around a million pounds: No one has ever thought about how much a cloud can weigh when we look at it from the ground. According to the USGS, an average weight of a cloud can weigh up to a million pounds. The weight is as heavy as the world’s largest jet when it’s full of cargo and passengers.
Bananas are radioactive: While eating bananas in our day-to-day life, we have never thought about how much bananas can be harmful to our bodies. Bananas contain potassium, and we all know that potassium decays, which makes the banana slightly radioactive. But you don't have to worry. To die of banana-induced radiation poisoning, you will have to eat ten million bananas in one sitting.
It can rain diamonds on other planets: On planets like Neptune, Uranus, and Saturn, extreme pressure crystallised carbon atoms and turned them into diamonds, according to various reports. To prove this fact, the researchers were able to create the same conditions in a lab. It is speculated that it may rain as much as 2.2 million pounds of diamonds on parts of Saturn every year.
Helium can work against gravity: Helium has a unique quality of working against gravity. Helium can be cooled to extreme temperatures, a few degrees away from absolute zero, and it turns into a superfluid, which means it can flow without friction. It can also climb up and over the sides of the glass, and it can leak through molecule-thin cracks in a container. Even if helium is the second most abundant element in the world, it can be harmful to the human body.
A cockroach can live for up to one week without its head: It is known that humans are alive because of the oxygen that we inhale which helps our body in our survival. But there are some creatures that can remain alive even without their head, such as cockroaches. Cockroaches do not breathe from their lungs due to their open circulatory system, but they breathe through the holes in their body segments. They can only die because, without a month of the head, they cannot drink water and die of thirst.
1. What are the various branches of Science?
Ans. Science deals with the concept of application of theoretical knowledge of laws and discoveries in day-to-day life. There are many branches of science including physical science, earth science, and biological science.
2. What are the various applications of Science in everyday life?
Ans. The applications of science in everyday life include travelling from one place to another by vehicles and automobiles, household appliances ranging from kitchen utensils to entertainment devices like TV, medications, and many more.
In 2500-1200 BCE, the ancient Egyptians believed that the disease was mainly caused due to the invasion of the bodies caused by the evil forces of the spirit. Thus, they included prayers and incarnation along with the use of medicines.
The Ebers Papyrus written around 1600 BCE, contains medical recipes for treating diseases related to the eyes, mouths, skins, internal organs, and extremities, as well as abscesses, wounds, burns, ulcers, swollen glands, tumours, headaches, and even bad breath.
History of Science
1. What is the use of Science in our daily activities?
The use of Science in our daily habitual activities begins in the morning itself. We get up, make our bed and brush our teeth. The toothpaste we use is made up of chemical science. The food we eat, the clothes we wear, and the oil or cosmetics we apply are all related to Science.
2. Who is known as the Father of Science?
Galileo Galilei is known as the Father of Modern Science. He was a known physicist, teacher, philosopher, and astronomer. His contributions and philosophies have shaped modern science.
3. Which field is known as the Mother of Science?
Mathematics is known as the Mother of Science. Just as every mother can solve her children's problems, Mathematics is known for solving every problem of other sciences.
