Science, technology, and society have always been intertwined. Science and society accelerated further as new technologies were invented and facts were discovered. For example, Alexander Graham Bell, a Scottish engineer and scientist, invented the first telephone with practical function. His invention gave science a new dimension and made communication easier. Similarly, when Newton gave his

The surface of the Earth is a breathtaking sight to see. Even the deepest canyon, though, is only a speck on the surface of the world. To have a true understanding of the Earth, you must travel 6,400 kilometres (3,977 miles) beneath its surface. The Earth is made up of four separate layers, which begin

Who Coined the Heisenberg’s Uncertainty Principle? This principle was proposed by German physicist Werner Heisenberg in 1927. Heisenberg’s uncertainty principle challenges the correctness of calculation of momentum and position at the same time and places restrictions on the same. The more accurate the position calculation is, the less precise the measurement of momentum will be.

Named after the astronomer Edmond Halley, Halley’s Comet is a periodic comet that returns to earth after a period of 75 years. It was last witnessed in 1986 and is likely to appear again in the year 2061. Edmond Halley was curious to study the comets seen from earth in 1531 and then 1607 and

Introduction A frame of reference is an abstract coordinate system with an origin, direction, and scale given by a collection of reference geometric points whose position is both mathematically and physically identified in physics and astronomy. The requirement to differentiate between multiple interpretations of “frame of reference” has resulted in a plethora of words. The
