In the 19th era, biological science emerged from the medical traditions of Ayurveda and old Egyptian medicine back to the idea of biology. The term “biology” was coined by Lamarck and Treviranus. Treviranus is not only a German physician but also a naturalist L0020766 Jean Baptiste Pierre Antoine de Monet Lamarck. Photogravure Credit: Wellcome Library, … Read more
Atm in chemistry refers to atmospheric pressure. It is described as the pressure imposed by the weight of the atmosphere, which has a mean value of 101,325 pascals at sea level (roughly 14.6959 pounds per square inch). ATM stands for standard atmosphere, a non-SI, non-metric, yet extremely practical measure of pressure. 1 atm corresponds to … Read more
The point on the principal axis where incident parallel rays meet after reflection from the mirror is known as the focus. The focus of a mirror is at the center of the optical system. The distance from the focus to the mirror end is called focal length, also known as flange distance. When light enters … Read more

The records of science fiction date back to the 17th century. It has been used for social criticism and satire, exploring new ideas, examining the human condition, and having hope. Science fiction is prevalent in contemporary culture, as seen in several films and television programs. Science Fiction literature is normally stated to have four fundamental … Read more
In chemistry and physics equations, “R” represents the gas constant, molar gas constant, general gas constant, or universal gas constant. A proportionality factor links energy scales and temperature scales in multiple equations. Gas Constant in Chemistry The gas constant has numerous names in chemistry, including the ideal gas constant and universal gas constant. It is … Read more
Atm in chemistry refers to atmospheric pressure. It is described as the pressure imposed by the weight of the atmosphere, which has a mean value of 101,325 pascals at sea level (roughly 14.6959 pounds per square inch). What is the standard pressure in ATM? Not prevalent beyond the United States. Normal atmospheric pressure is 14.7 … Read more
Have you ever witnessed the swelling of wooden doors or window frames during wet seasons? Or do the seeds expand when stored in the water? Do you understand why this occurs? It occurs due to a process called imbibition that occurs within the plant cells. During imbibition, the water molecules or other liquid molecules are … Read more
Female flower clusters are clustered on the stem of the corn cob plant, indicating that it solely produces female flowers. This flower’s surface is coated in the spat. These are known as tassels because their length causes them to dangle from the blooms in the form of a cluster. The tassels found at the top … Read more
A cell is an electrical energy source that uses chemical reactions to generate a current. An electrical cell is an ‘electrical power supply. It converts stored chemical energy into electrical potential energy, which can be used to provide electricity. A cell acts as a ‘battery.’ The chemical reactions create the electromotive force that drives an … Read more
If the body does not move or change its position with respect to the surroundings or frame of reference, it is said to be at rest. The person is said to be at rest on a bus or in the cinema. The body can also change its position and be said to be moving or … Read more
In East Lansing, Michigan, one of the lengthiest investigations in the history of science was initiated more than a century ago. Every two decades, scientists examine it. This week, after an additional delay caused by a pandemic, the time was ripe again. In April 1879, William Beal buried 20 bottles with sandy soil and more … Read more
According to modern science, the Sun is 4 1/2 billion years old. Our cosmological systems have always been centered on the Sun. However, with the advent of modern astronomy, humanity has realized that the Sun is just one among many stars in the universe. It is a typical G-type main-sequence star (G2V, sometimes known as … Read more
Aristotle is the Father of Biology. He is the Greek philosopher who visited Lesvos in the fourth century BC, an island in the Aegean that was then, as it is now, teeming with wildlife. His interest in what he discovered there and his diligent research resulted in the formation of new science, Biology. Biology is … Read more
Carbon (C) is a nonmetallic chemical element belonging to Periodic Group 14. Although carbon is abundant in nature, it accounts for only around 0.025 percent of the Earth’s crust, and yet it produces more compounds than all the other elements combined. In 1961, the isotope carbon-12 was chosen to replace oxygen as the standard against … Read more
If you’re asked who is the father of chemistry, your best guess is probably Antoine-Laurent Lavoisier, who published “Elements of Chemistry” in 1787. He created the first comprehensive, at the time, list of elements, found and named oxygen and hydrogen, contributed to the development of the metric system, assisted in revising and standardizing chemical nomenclature, … Read more
Newton’s third law quantifies thrust as a reaction force. When a system evacuates or accelerates mass in one direction, the accelerated mass causes an equal magnitude force to be applied in the other direction. If you’ve been swimming, you may feel your weight has decreased. It is because any fluid acts upward on a submerged … Read more
Physics did not necessarily have a father, and no one invented physics either. It was always close by, and as long as humans were curious about the planet, discoveries would be made. That is what scientists do; they find new things. It’s easy to imagine someone thousands of years ago discovering that rapidly rubbing two … Read more
The science of human development seeks to understand the processes that organisms undergo during growth and change. Researchers primarily investigate the following three questions: How do humans develop? What makes humans develop differently from other animals? What are the consequences of individual differences in development, and how can they be maintained or managed? By approaching … Read more
A barometer is a type of scientific equipment used to determine an area’s air pressure. Pressure trends can be used to anticipate short-term weather changes. Numerous air pressure measures are employed in different weather analyses to identify surface trough, differential pressure, and continental borders. Barometers and pressure altimeters (the simplest and most frequent form of … Read more
