Advantages and Disadvantages of Space Exploration

Outer space has been a subject of equal measure of elusiveness and excitement for human beings. We were all taught about the Earth and its surrounding atmosphere in our science lessons. And the information that we have acquired about everything beyond our sight could not have been possible without space explorations. So here is a look at some benefits of space exploration and some challenges faced in the process. WHAT IS SPACE EXPLORATION? Space exploration is a type of investigation of the cosmos beyond our Earth. This is using the assistance of certain instruments, for instance, a satellite, spacecraft, telescope, or launch vehicles. That is to say that space exploration is simply the use of technology to study outer space. We have an illustrious history of studying space and celestial...

Advantages and Disadvantages of Stem Cell Research

Healthcare has come a long way. The way that diseases are treated now is very, very different from the way that they have been treated hundreds of years ago. Moreover, the kind of diseases that existed has also changed. Various diseases have been eradicated, cured, or made less harmful. All of this has happened by combining various types of medicinal fields. These fields also keep on evolving each and every day. The latest in the field of medicines is stem cell research. Just like other forms of medicine, it has its own advantages and disadvantages. So let us look into it. WHAT IS STEM CELL RESEARCH? As is evident from its name, stem cell research refers to the scientific study of stem cells. It studies the properties of stem cells and their potential use in medicine. In other words, ...

Advantages and Disadvantages of Science Exhibitions

The world is currently being shaped by science and technology in every aspect of our lives. And there is no exception when it comes to the field of education, especially science education. Scientific education has acted as an important facilitator to enable students and people to face numerous global challenges like climate change, pollution, poverty, hunger, etc. A great way of involving bright young minds into the field of science education is through their participation in science exhibitions. So let us look at the benefits and the drawbacks of science exhibitions. WHAT IS A SCIENCE EXHIBITION? Science exhibition, also known as a science fair, is an event conducted by an educational institution or organization to allow students to present their respective science projects. These exhib...

Advantages and Disadvantages of Qualitative Research

Scientific research is a detailed study of a problem to find a solution. There are various methods of formulating a particular research model. Qualitative and quantitative research are two broad approaches to the collection of data for the study. Lately, researchers have been widely using the qualitative research method. Let us look at the advantages and disadvantages of this mode of research. WHAT IS RESEARCH? Research is the study or systematic investigation that is directed towards the discovery of some fact. It is a careful and detailed study of a subject to discover new information or to reach a new understanding. The Organisation for Economic Cooperation and Development (OECD) defines research as "any creative systematic activity undertaken to increase the stock of knowledge, inclu...

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 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 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,...
