The human brain is the command center of the human nervous system. The human brain receives signals from the body’s sensory organs. It weighs up to 1.4 kilograms and makes upto 2% of total body weight. On average, male brain is about 10% larger than the female brain. The main part of the brain is […]
The Raman effect was discovered in 1928 and was named after the Indian scientist Sir C. V. Raman. Raman was awarded the Nobel Prize in Physics in 1930 for this discovery of Raman scattering. The Raman effect or Raman scattering is the inelastic scattering of photons by matter, where there is an exchange of energy and a change […]
Do you think it is possible to convert plastics into vanilla flavouring?.The answer is “YES”.Recently scientists have pioneered a technology that uses genetically modified bacteria to turn used plastic bottles into vanilla-flavouring. So in future we can eat vanilla ice cream that is made from plastic bottles. We know that there has been a growing […]
Environmental degradation is the major issue that we are facing today. each second environment is polluted due to various human activities. Increased population growth and industrial and agricultural activities contribute to environmental pollution. The major environmental issues are:- Climatic Change Climatic change is the major issue we are facing in the past few years. Increase […]
Have you ever wondered why few insects like water striders walk in water? or why do small droplets of rain stick to our window?. The scientific explanation of this phenomenon is associated with the term “Surface Tension”. Surface Tension is the tendency of the surface of a liquid to contract until it reaches the smallest […]
The vibration that propagates as an acoustic wave, through a transmission medium such as a solid,liquid or gas is known as sound. Only acoustic waves that have frequencies in the audio frequency range, that is frequencies lying between about 20 Hz and 20 kHz, elicit an auditory percept in humans. Ultrasound Sound waves are sound […]
Vitamin D is a fat soluble vitamin which is both a nutrient and a hormone. Two types of vitamins have been found in nature. Ergosterol (D2), found in plants and Cholecalciferol (D3) . Cholecalciferol is synthesized in our skin with the help of sun exposure. It can also be provided to our body through our […]
In earlier days the main causes of death were infectious diseases but today death is mainly caused due to hypokinetic diseases. Hypo kinetic diseases are conditions caused mainly due to sedentary lifestyle. Today technology is very much advanced, mankind is designing machines to move for him so the need to run and walk is reduced […]
A Newton’s cradle is also called a Newton’s pendulum, Newton’s rocker or a ball clicker. It was named after the great physicist Sir Isaac Newton and was designed by Edme Mariotte. Newton’s cradle demonstrates the principles of conservation of energy and conservation of momentum with swinging spheres. Newton’s cradle consists of several balls […]
