You have always learned that a living system can grow, sustain, and reproduce itself. The most remarkable thing about a living system is that it itself is composed of non-living atoms and molecules. The scientific study of what goes on chemically within a living system falls in the domain of biochemistry. Living systems are composed of various complex biomolecules such as carbohydrates, proteins, nucleic acids, lipids,

At some point or the other, we’ve all marveled at how diverse the living world around us is. Detailed scientific studies of these organisms only emphasized their diversity even more. However, there also exists unity underlying this diversity – and the theory that emphasizes this unity is the cell theory. The cell serves as the fundamental structural and functional unit of all living organisms. It is

When we feel unwell or when our body is giving us signals that something might be wrong, we turn to doctors to provide the support and care that we need, and trust they will be able to identify the cause of our health problems and help us heal. Trust is an important aspect of any doctor-patient relationship. Some people trust their doctors so much that they

Want to have a great career in chemistry and other natural sciences? You should apply for one of the best chemistry courses from the best universities in the world. Chemistry is a vast subject that finds applications in a huge number of fields – everything from drug metabolism to cleaning detergents to rocket science. For centuries, it has given us many useful products for improving our

Underwater life has always been a very interesting topic for human research. Aquatic life seems so fascinating that we try to dig as much information as we can about those amazing creatures that are destined to live their whole life submerged in water. We all know that oceans cover more than 70% of the surface of the earth. We can’t rule out the fact marine species

Many households use energy for various applications, including cooking, audiovisuals, room temperature control, lighting, and the rest. As a result of individual needs, the rate of energy consumption in a home may differ from that of another. The amount of money you spend on energy bills depends on the amount of energy you consume and your tariff. For this reason, many households seek amazing energy deals

Coronavirus or 2019-nCoV is rapidly spreading worldwide and has been considered as an international health emergency by the WHO. The spread of the Virus started from Wuhan, China and has infected and killed thousands of people around the globe. However, the risk of coronavirus spreading still prevails and no vaccination or cure has been found until now. What’s coronavirus? Coronavirus is from a family of viruses

The invention of miniaturized motors and their integration into many mechanical equipment use in different industries have not only improved the way these industries work, they have also revolutionized the very machinery they work with. One of the biggest examples of this phenomenon involves the healthcare industry, with many life-saving and healing equipment becoming more effective in their roles, thanks to the addition of medical miniature

Gone are the days when doctors had to cut and prod in order to find the ultimate cause of someone’s medical problem. Now with all the advances in technology, especially in the area of nuclear imaging, a simple scan can most often get to the root of the problem without the need for what was once a common practice, exploratory surgery. In fact, it wasn’t all

Chemistry is one amazing subject. It begins with just an atom and rises to simple substances and then goes above complex polymers – and then again down to subatomic particles. I have been writing a lot recently on how to read, revise and make notes etc., to help you become a better student. Class chemistry notes aren’t always the best solution and if you are aspiring

“Blood Facts” – seriously? Like all humans who have red colored blood, there are few organisms which have varying blood colors. Spiders and octopus have blue color blood, cockroaches have white/colorless blood, grasshopper, leeches, and some varieties of earthworm have green color blood and so on. Apart from these, there are more facts about the blood. In this article, few interesting facts about Blood and Blood

In a collaborative attempt, astrophysicists from different institutions have found success in discovery of A1689B11 – a spiral galaxy that’s said to be the oldest discovered. The research reports an integral-field spectroscopic (IFS) observation of this gravitationally lensed spiral galaxy. It is the most ancient one till date and is calculated to be 11 billion years old, which means it existed after just 2.6 billion years after

What are perseids? Perseids are the regular and most predictable meteor shower which appear regularly every year. They are associated with Swift Tuttle comet and appear to rise from the radiant in the constellation Perseus. Swift Tuttle comet, formerly known as 109P, travels toward Earth’s part of solar system every 133 years leaving traces of perseids. It was last seen in 1992 after its discovery year

Every student or graduate knows how hard the first experience of passing exams is. Preliminary preparation starves the nervous system and the physical condition of the human body, however, the exam itself is always a stressful situation, which requires a candidate a great manifestation of mental and physical abilities. Therefore, just the knowledge of a subject is not enough for the exam. The examinee needs to

Sequence of real numbers A sequence of real numbers (or a real sequence) is defined as a function $ f: \mathbb{N} \to \mathbb{R}$ , where $ \mathbb{N}$ is the set of natural numbers and $ \mathbb{R}$ is the set of real numbers. Thus, $ f(n)=r_n, \ n \in \mathbb{N}, \ r_n \in \mathbb{R}$ is a function which produces a sequence of real numbers $ r_n$ .

About This post is actually a summary of a research project I took under INSPIRE-SHE Scholarship Program by the Dept. of Science and Technology, Govt. of India. My plan was to make the content open-source on the web that faults could be corrected by time. The language is simple and very easy to understand and the ease of understanding is focused on A-level (10+2) students and beyond.

Fermat Numbers, a class of numbers, are the integers of the form $ F_n=2^{2^n} +1 \ \ n \ge 0$ . For example: Putting $ n := 0,1,2 \ldots$ in $ F_n=2^{2^n}$ we get $ F_0=3$ , $ F_1=5$ , $ F_2=17$ , $ F_3=257$ etc. Fermat observed that all the integers $ F_0, F_1, F_2, F_3, \ldots$ were prime numbers and announced that $ F_n$
