Introduction The “radioactive beta decay” process exists in the field of nuclear physics. The radioactive process of decay is associated with the process of reaction in which beta ray is released from the “nucleus of an atom”. It helps in the transformation of the “original nuclides” to isobars” of the nuclide. In simple terms, in the process of “beta decay”, the “neutron” transforms into a “proton” through the “emission of an electron” which is further accompanied by “antineutrino”. The process of “beta decay” is resultant of a weak force which makes the “decay process” a relatively lengthy process. What is ... Read More

Introduction “Radioactive Decay” emits energy in “ionizing radiation form” and is also responsible for damaging the genes’ DNA and biological tissues in the human. The ionizing radiation is mainly incorporates beta particles, gamma rays, and also alpha particles. Individuals who are more exposed to the harmful radiation of these three rays can suffer from various skin diseases, respiratory diseases, DNA problems, and biological tissue deformities. The radioactive elements are present in various forms in the periodic table where some of them are unstable and some of them are stable. What do you mean by Radioactivity? The ... Read More

Introduction In the process of nuclear decay the elements that are usually released alpha particles and gets decay gradually with time are determined as the radioactive alpha decay products. The alpha particles that is structurally equivalent to the Helium atom’s nuclear are mainly denoted by the Greek letter, α. These alpha particles mainly consist of two neutrons and two protons. In radioactivity alpha decay, there is a positively charged element that is identical to Helium 4 nucleus and that particle can also be emitted spontaneously. This article is mainly determined as the alpha particle What do you ... Read More

Introduction Sphygmomanometer, the original blood pressure device is used for measuring the blood pressure. This machine or instrument is used in the medical field and it has its importance. It has different names like blood pressure meter and blood pressure gauge. It includes a measuring unit, an inflatable cuff, and a device to inflate the cuff. It is used for measuring blood pressure and blood pressure stands for force applied to the artery walls. Definition of a sphygmomanometer Sphygmomanometer is an instrument used in the medical field for the measurement of blood pressure. It is also known as ... Read More

Introduction Pressure is the term that is used in several sections of physics. The term, pressure is given in the form of different units. The Bar and Atm are the two units that help in the representation of pressure. The bar The Atm as the pressure metric unit denote the atmospheric pressure The word bar is derived from the Greek word, baros, which means weight. Relationship between bar and ATM A bar is a metric unit that is used to determine the amount of pressure; however, this is not the part of ... Read More

Stephen Hawking is considered the most practical theoretical physicist since Albert Einstein. He died on 14th March 2018, at the age of 76. He was diagnosed with a motor-neuron disease, amyotrophic lateral sclerosis (ALS) when he was only 21 years old. He is a real hero who despite his physical condition continued his research on Black holes and became one of the world-renowned scientists of all times.Professor at Cambridge, Stephen Hawking worked on the basic laws which govern the universe. His famous Hawking Radiation theory pronounces that "black holes leak energy and fade into nothing". The equation that he came ... Read More

The screw gauge is an instrument used for measuring exactly the diameter of a thin wire or the width of a sheet of metal. It comprises of a U-shaped mount which is fixed with a screwed pin which is fixed to a thimble. Side by side to the axis of the thimble, a scale passed in mm is inscribed. Having a U shaped metallic mount, a screw gauge measures even the tiniest length with exact accuracy.Just like Vernier calipers, a screw gauge also holds two scales - a key scale and an additional scale. The key scale is a millimeter ... Read More

We all know about the great British physicist and world-famous scientist, Stephen Hawking who is considered the most practical theoretical physicist since Albert Einstein. At the young age of 22, Hawking contracted Amyotrophic Lateral Sclerosis (ALS) also referred to as motor neurosis.It causes muscle twitching and deterioration of muscles which leads to gradual degeneration of muscles, difficulty in swallowing, talking and even breathing. Initially, doctors predicted that he will be alive only for 2 years. But the genius went on to live till he turned 76 and passed away in March 2018.A person which such rare degenerative disease went on ... Read More

A Light bulb generally has a wire connected to it. But this levitating light bulb just hovers in the air above a wooden block and draws power from it. This bulb even rotates if spun. This wooden block is of course connected to the switchboard for power.How Did It Hover?This levitating light bulb makes the look interesting when it just hovers gracefully above the wooden block while it glows. As it is evident from the basic principles of magnetism that like poles repel, the bottom of the bulb contains a magnet and lets it hover on the wooden block which ... Read More

The Q-point or quiescent point of a transistor is considered during amplification, as this is the point of amplification where the signal is completely amplified without any kind of attenuation. This is located when the transistor is operated in the active region.Locating On A GraphWhen a value for the maximum possible collector current is considered, that point will be present on the Y-axis, which is nothing but the Saturation point. As well, when a value for the maximum possible collector-emitter voltage is considered, that point will be present on the X-axis, which is the Cutoff point.When a line is drawn ... Read More
