Byju's app was developed by Think and Learn Pvt. Ltd, a company which was established by Byju Raveendran, Divya Gokulnath and a group of students in 2011. [ 11 ] [ 1 ] [ 12 ] Byju, an engineer by profession, was coaching students in mathematics since 2006.
Byju was born in 5th January 1980 in the Azhikode [1] [2] village of Kerala, India to Raveendran and Shobhanavalli, physics and mathematics teachers, respectively. [3] [4] He studied at a Malayalam medium school where his mother was a mathematics teacher and his father a physics teacher. [5] [6] He would skip classes and then learn at home. [7] [8]
In 2011, Divya and her husband co-founded Byju's, an online education platform initially providing in-person education to support school learning, followed by an online app that features video lessons. [11] [12] [13] With her expertise, Divya has served as a teacher in some educational videos. [14]
Portal:Physics/Did you know/5 . Mock mirage of the setting sun... the mirage of astronomical objects is an optical phenomenon, which produces distorted or multiple images of astronomical objects such as the Sun, the Moon, the planets, bright stars and very bright comets
Physics (from Greek φυσική (ἐπιστήμη), i.e. "knowledge of nature", from φύσις, physis "nature"), is the natural science that involves the study of matter (anything that has mass and occupies space) and its motion (movement from place to another) through space and time, light and its propagation, along with related concepts ...
Physics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines. A scientist who specializes in the field of physics is called a physicist. Physics is one of the oldest academic ...
The one anisotropic shape whose excluded volume can be expressed analytically is the spherocylinder; the solution of this problem is a classic work by Onsager. [6] The problem was tackled by considering the distance between two line segments, which are the center lines of the capped cylinders. Results for other shapes are not readily available.
In physics, attenuation (in some contexts, extinction) is the gradual loss of flux intensity through a medium. For instance, dark glasses attenuate sunlight, lead attenuates X-rays, and water and air attenuate both light and sound at variable attenuation rates. Hearing protectors help reduce acoustic flux from flowing into the ears.
