UPSC - Crash Course - General Science

Nature of Science (often abbreviated as NoS) is a term that refers to various topics related to sociology, philosophy, and history of science. It is a metacognition 
about science's products in an interdisciplinary analysis of these areas of knowledge, together with specialists in didactics of science and scientists.

Nature of Science

Science is the concerted human effort to understand or to understand better, the history of the natural world and how the natural world works, with observable 
physical evidence as the basis of that understanding.

What is Science?

This is a method of procedure that has characterized natural science since the 17th century, consisting in systematic observation, measurement, and experiment, and the formulation, testing, and modification of hypotheses.
​​

Scientific Method

This is a Case study on scientific methods.

Scientific Method - Case Study of Experience

Everyday Science explores science concepts from the everyday and beyond. It has made a lasting impact on regarding each and every field of human existence.Whether it is concerned with our day to day lives or whether it is related to the various modern developments which have resulted in elevating the living standards of the individuals.

What is Everyday Science?

Crime novelists and war reporters often refer to the ‘smell of death’ when encountering a dead or decomposing body.
The characteristic odors of rotting flesh are difficult to forget once experienced and are generally recognized as being worth avoiding, but what is it that makes a dead body smell so bad?

Magnificient Molecules

Physics is a systematic study of the natural world, a discipline that attempts to quantify reality through a precise application of observation coupled with logic and reason. In order to make use of such a discipline, of course, there is certain foundational information that you must have first, in order to build upon it.

Basic Physics Concepts

This is a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously.

Electromagnetic Radiation

Light is the natural agent that stimulates sight and makes things visible.Here we will discuss the basics of Light.
​​

Light

Sound is the vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.We discuss the basics of sound in this lesson.

Sound

Electricity is the set of physical phenomena associated with the presence of electric charge. We discuss the basics of Electricity starting from series and parallel circuits.

Electricity

Magnetism is one aspect of the combined electromagnetic force. It refers to physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects.

Magnetism

Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. We will discuss his 3 laws.

Newtons Laws

Newton's law of universal gravitation states that a particle attracts every other particle in the universe using a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their center. Info Credit: www.edumedia.fr

Gravitation

Space colonization (also called space settlement, or extraterrestrial colonization) is permanent human habitation of the planet Earth. Many arguments have been made for and against space colonization but we do not discuss the arguments here but concentrate on colonisation strategies etc.

Space Colonization

Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work i.e., energy in the process of transfer from one body to another.

Energy

Nanoscience and nanotechnology are the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.

Nano Technology

Science is the systematic way of acquiring knowledge through observation and experimentation, whereas technology is the practical application of science. Technology is used to design products that improve the quality of human life.

Ministry of Defence (India) - The Ministry of Defence (abbreviated as MoD) is charged with coordinating and supervising all agencies and functions of the government relating directly to national security and the Indian armed forces.

Ministry of Defence

Defence Research & Development Organisation (DRDO) works under Department of Defence Research and Development of Ministry of Defence. DRDO dedicatedly working towards enhancing self-reliance in Defence Systems and undertakes design & development leading to production of world class weapon systems and equipment in accordance with the expressed needs and the qualitative requirements laid down by the three services.

DRDO

In modern language, a missile is a self-propelled precision-guided munition system, as opposed to an unguided self-propelled munition, referred to as a rocket.

Guided Missiles: Part 1

In much the same manner as aircraft, missiles are typed by their general characteristic grouping. Such a grouping may show in what manner a missile is used, but it will not identify a particular missile. This general classification makes use of three items: (1) launch environment,(2)target environment (or mission), and (3) type of vehicle.

Guided Missiles: Part 2

A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion (thermonuclear weapon).

Nuclear Weapons and Weapons of Mass Destruction

India possesses weapons of mass destruction in the form of nuclear weapons and, in the past, chemical weapons. Though India has not made any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 110 nuclear weapons.

India Nuclear Weapon Program

The business opportunities arising out of the mandatory offset provisions in the defence import contracts provide ample scope for the Indian Defence Industries to get state of the art technology and if effectively absorbed by us, in due course, we can progress substantially towards achieving self-reliance in indigenous design and manufacture of defence products.

Issues with Technology in India’s Defence

Science, a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about nature and the universe. Technology, the collection of techniques, methods or processes used in the production of goods or services or in the accomplishment of objectives, such as scientific investigation, or any other consumer demands.

Science vs Technology

A process of rigorous reasoning based on interactions among theories methods, and findings. Builds on understanding derived from the objective testing of models or theories.

Guiding Principles of Scientific Research

What is all the matter in the Universe made of? and What holds it together?All matter is comprised of Leptons and Quarks.Force carrier particles hold all matter together.(There are 4 fundamental forces – Strong, Weak, Electromagnetic, Gravity).

Small Particles - Part 1

Small Particles - Part 2

What are asteroids and how are they classified (Astronomy)?Are they a threat to Earth (Geology)?Do we already have samples (Meteoritics)?
The answers to all three have origins with the ‘state of science’ in 1804.

Space Rocks

We do not inherit the earth from our parents, we borrow it from our children” – Chief Seattle.

Energy Conservation

Earth is a dynamic planet with the surface and interior in a constant state of flux.

Earth Composition and Processes

The Sun, its planets and other objects in orbit are all together known as the solar system.

Solar System in Galaxy

Cell—Basic unit of structure and function in organisms. Some organisms, like bacteria and protists, are unicellular (made entirely of one cell).Some organisms, like fungi, plants, and animals, are multicellular (made of many cells).

Organisms are Cellular Based

Define interspecific competition and give examples.Define intraspecific competition and give examples.

Organisms Compete for Food etc

Evolution means change over time. A scientific theory is not just a belief, it is a well-supported tested explanation.

Evolution

Gene – basic unit of genetic information. Genes determine the inherited characters.Genome – the collection of genetic information.

Genetics

The more genetic variation within a population, the better chance it has to survive.

Evolution of Populations

The last 50 years have seen an increasing emphasis on ethical, moral, social, legal, political and economic implications of science.
