Science

SummaryScience is a way of knowing about the world. At once a process, a product, and an institution, science enables people to both engage in the construction of new knowledge as well as use information to achieve desired ends. Science Literacy: Concepts, Contexts, and Consequences.

Science is based on research, which is commonly conducted in academic and research institutions as well as in government agencies and companies. The practical impact of scientific research has led to the emergence of science policies that seek to influence the scientific enterprise by prioritizing the development of commercial products, armaments, health care, and environmental protection.

Advantages and Disadvantages of Chemical Machining

The manufacturing industry widely uses non-traditional machining processes for the purpose of manufacturing complex and accurate parts and components. Aerospace, automotive, and electronic industries are only some industries that widely use these non-traditional machining methods for the precision it showcases. Chemical machining is one such type of non-traditional machining process that is quite popular and well known. So here are the advantages and disadvantages of this method. WHAT IS CHEMICAL MACHINING? Chemical machining ( also called photochemical machining or photochemical milling) is a non-traditional machining process where there is the production of desired metal shapes by controlled chemical attack with strong acidic or alkaline chemical reagent. It removes metal from a machin...

Advantages and Disadvantages of Biomass

The world is reeling due to the unprecedented effects of climate change. We are currently facing a global climate emergency. There are relentless efforts ongoing for the process of moving into a low-carbon and sustainable future. One of the ways to call for action is to invest in cleaner energy like biomass energy. But is it as efficient and clean as it claims? WHAT IS BIOMASS? Biomass is an organic plant or animal material used for the production of energy. It uses stored energy from the sun. The process of photosynthesis absorbs the energy derived from the sun. When biomass is burned, the energy is then released as heat. It can be directly burned or converted into fuel like biogas or biofuel. Plants, woods, manure, and any waste are examples of biomass material. They are also useful in...

Advantages and Disadvantages of Human Cloning

The advent of biotechnology has brought with it revolutionary and destructive discoveries equally. One of the more controversial subjects of this technology is cloning. Cloning is a process of taking genetic matter from one organism and creating an identical copy of it artificially. This has been extensively studied, discussed, debated. Hence, it is no surprise that the possibility of human cloning is even more controversial. So, let us look at the arguments that prevail on both sides for a valid opinion. WHAT IS CLONING? The word “clone” is derived from the Greek word klōn meaning ‘twig’. It was first coined by an American plant physicist, Mr. Herbert J. Webber to describe the process of creating a new plant with a twig. Cloning has come to mean any artificial, identical genetic copy of...

Advantages and Disadvantages of Fracking

As the world keep modernising, it needs more and more energy to run. This energy is obtained from various sources. Energy sources can be classified into two broad categories on the basis of their nature. These categories are – renewable and non-renewable. Renewable energy sources including solar energy, wind energy, hydro energy, et cetera. Non-renewable sources of energy are fossil fuels. Furthermore, there are various types of fossil fuels. These include natural gas, petroleum, coal, et cetera. There are also multiple ways to obtain these fuels. One of those ways is fracking. As is true of all things, fracking has its own advantages and disadvantages. WHAT IS FRACKING? Fracking is short for “hydraulic fracturing”. It is the process of drilling deep into the ground to extract fossil fue...

Advantages and Disadvantages of Clinical Trials

There has been a recent surge in new-age diseases everywhere. The novel coronavirus disease (COVID-19) is rapidly spreading across nations. Unfortunately, there is no cure for it yet. While the death toll increases because of this pandemic, we are still waiting for a vaccine that could potentially save millions of lives. Research and clinical trials to find a solution are moving at breakneck speed because only a vaccine can prevent any further damage. Over 35 companies and institutions are racing to find the answer. So, this begs for us to look at how important the field of medical research is. WHAT IS A CLINICAL TRIAL? Clinical trials are a type of clinical research that studies new treatments and tests and evaluates their effects on human health outcomes. Studies are done on participan...

Advantages and Disadvantages Of Geothermal Energy

In dictionary terms, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object. However, in practical terms, it a life-sustaining resource without which humans cannot survive. There are various types of energy, depending on their source and their nature. One type of energy is renewable energy. A renewable form of energy is geothermal energy. Like all other forms of energy, it has its own advantages and disadvantages. WHAT IS RENEWABLE ENERGY? As the name suggests, renewable energies are forms of energy that can be renewed. This means that their supply is unlimited. It can also mean that its supply replenishes at a rate faster than that of its consumption. The most common examples include wind, solar, geothermal, biomass,...

Advantages and Disadvantages of Sexual Reproduction

Reproduction is vital for the survival of any species. Different organisms use different methods to reproduce. One of these methods is sexual reproduction, which has its own advantages and disadvantages. WHAT IS SEXUAL REPRODUCTION? Sexual reproduction is the method by which living organisms produce offspring by the process of fertilization. This process in seen in higher organisms. This involves a gamete that travels to fuse itself with a larger stationary gamete produced. The smaller gamete that travels to a larger one is produced by the male. This is known as the sperm cell. The large gamete is produced by the female. It is known as the ovum or the egg. The process of the sperm and ova merging is known as fertilisation. Fertilisation creates a single-celled zygote which includes...

Advantages and Disadvantages of Hydro Energy

Among all the types of renewable energy, hydro energy is one of the most prominent ones. Governments all across the world have set up mechanisms to harness hydro energy. India also has a huge number of dams, nearly 2000 dams across the country. Like all other forms of energy, there are various advantages and disadvantages of hydro energy. WHAT IS HYDRO ENERGY? Hydropower is the energy obtained from water. Running water through turbines convert the kinetic energy of water into mechanical energy. This is done by constructing dams on already existing water bodies. These dams create a reservoir of the water present in the water body. Water falls from a height which creates force to turn the turbines. Furthermore, tidal energy is another form of hydropower. Tidal power is the r...
