The Elephanta Caves are a compilation of rock-cut cave temples devoted to the Hindu God Lord Shiva. They are believed to be built between the 5th and 7th centuries. Various indigenous dynasties contributed to these decorated temples. The monuments are placed on Elephanta Island near Mumbai, western India. As remarkable as these caves are, they are cut out of the solid basalt rock, the second hardest rock on earth. Most of the carvings narrate Hindu mythologies and even depict complex Yogic postures. The cave temples were in use by worshippers and devotees until the arrival of Portuguese colonialists on the island of Elephanta. The artwork carved is primarily that of Shaivism, Shaktism and Vaishnavism - three popular sects of Classical Hinduism. Major Hindu deities and Gods like Vishnu, Shiva, Nandi, Durga and Brahma are shown on the walls of these caves, carved beautifully. The architecture seen in these caves is something special. As magnificent as they look from outside, ...

What Are Lucid Dreams? Lucid dreams are when you know that you’re  dreaming  while you’re asleep. You’re aware that the events flashing through  your brain  aren’t happening. But the dream feels vivid and real. You may even be able to control how the action unfolds as if you’re directing a movie in your  sleep . Studies suggest that about half of people may have had at least one lucid dream. But they probably don’t happen often, usually only a handful of times in a year. When Do Lucid Dreams Happen? Lucid dreams are most common during rapid eye movement (REM) sleep, a period of very deep sleep marked by eye motion, faster breathing, and more brain activity. You usually enter REM sleep about 90 minutes after falling asleep. It lasts about 10 minutes. As you sleep, each REM period is longer than the one before, finally lasting up to an hour. Lucid Dreams Research Neuroscientists don’t know exactly how and why lucid dreams happen. But they have some ideas. The risk...

Qn.1) Which among the following is/are factors that affect Rossby Waves? 1.  Rotation of earth 2.  Coriolis effect 3.  Revolution of earth Select the correct answer using the codes given below: (a)  1 only (b)  2 and 3 only (c)  1 and 3 only (d)  1, 2 and 3 Ans: (d) 1, 2 and 3 Understanding The meandering jet streams are called Rossby Waves. Rossby waves are natural phenomena in the atmosphere and oceans due to rotation of earth. In planetary atmospheres, they are due to the variation in the Coriolis effect (When temperature contrast is low, speed of jet stream is low, and Coriolis force is weak leading to meandering) with latitude. Rossby waves are formed when polar air moves toward the Equator while tropical air is moving poleward. The existence of these waves explains the low-pressure cells (cyclones) and high-pressure cells (anticyclones).
