French novelist Annie Ernaux is the winner of the Nobel Prize in Literature 2022. She considers writing as a political act. Her writings reflect on inequalities prevailing in the society. Annie uses language as a “knife” to tear open the harsh realities of life. Her intensely personal books discuss incidents from her own life. They […]
Introduction: Quantum Mechanics, one of the crucial branches not only in Physics but also in many other fields. Developments and improvements in this field will really boost the world of Science. So, for their valuable and outstanding discoveries in Quantum Mechanics, the Nobel prize for Physics in 2022 has been awarded to Alain Aspect, John […]
Electromagnetic radiation happens all around us. It is produced as the result of interaction between electric and magnetic fields. The fields exist together. Electromagnetic waves tend to have a large range of frequencies/wavelengths. Radio waves, microwaves, infrared waves, visible light, ultraviolet, x-rays, and gamma rays are the seven types of electromagnetic spectrum. Radio waves are […]
A substance or material which allows electricity to flow through it is called a conductor or electrical conductor. In a conductor, when voltage is applied, electrical charge carriers (electrons or ions) move effortlessly from one atom to another. Metals like copper are considered good conductors. On the other hand, non metals are usually considered bad […]
Introduction An AC generator or Alternating Current Generator is a device which is used for converting mechanical energy into alternating energy in various appliances. While a DC generator uses direct current, an AC generator uses slip rings to produce alternating current. The AC generator produces AC current in bicycles, electric scooters and microwaves. The steam […]
Viscosity occurs when there is a relative motion between the fluid layers. So, in simple words what is viscosity? Most fluids offer some resistance to motion and this process is called viscosity. Scientifically, we can define viscosity as a measure of a fluid’s resistance to flow. The SI unit of viscosity is poiseiulle (PI). Other […]
There are enormous strange incidents and phenomena occurring throughout the world. People are more interested in such phenomena and they may be very eager and curious to sort out the real reason behind these strange occurings. Time travel is one among such topics that made many people crazy and enthusiastic. Research related to this topic […]
A collision is said to be done when the path of one body is changed by the influence of another body or when either two bodies physically collide against each other. Collisions involve forces which means there is a change in velocity. Closing speed is the magnitude of the velocity difference just before impact. Momentum […]
The Chernobyl disaster was one among the two nuclear energy accidents rated with maximum severity on the International Nuclear Event Scale. Chernobyl is a city, 130 km from Kyiv in the Ukraine republic of Soviet Union. 36 years ago, in 1986, an accident occurred in the reactor no:4 of the Chernobyl power plant due to […]
