Celebrating New Year? This can make it more Amazing!

 ORIGIN There are two stories about the origin of New Year:-   1st story - New Year wasn’t always celebrated on 1st Jan. The earliest New Year celebrations date back to about 4,000 years ago. At that time, the people of ancient Babylon began their New Year in March. They had an 11-day celebration at the beginning of Spring as the crops were being planted for the upcoming year. 2nd story - New Year on 1st January was declared by Julius Caesar, the Roman emperor. He declared 1st Jan as a national holiday after the name of the god Janus, the Roman God of doors and gates. Janus had two faces one looking forward and the other looking back. FACTS 1.) North America - People celebrate New Year by gathering family and friends for parties. Sometimes, meals and spectacular firework displays are also on. 2.) Greece - a gold or silver coin is mixed in the cake called a Vasilopita. The person receiving the piece of cake with the coin is said to be lucky for the rest of the year. 3.) Spain ...

Some Potentially Habitable Exoplanets

-

The Circumstellar Habitable Zone:-

The Circumstellar Habitable Zone is the range of orbits around a star within which a planet can hold liquid water given enough atmospheric pressure.

So here is the list of some Potentially Habitable Exoplanets:-

1.) Teegarden’s Star b.


This is an exoplanet orbiting the Teegarden’s Star, about 12 light years away from our Solar System. It is the fourth closest potentially habitable exoplanet. This is the innermost known planet orbiting the Teegarden’s Star with an orbital period of just 4.91 days. This planet is likely to be rocky. It may even have an ocean of water on its surface. It orbits within the habitable zone of its host star. Teegarden’s star is inactive and quiet, increasing the chances that Teegarden’s Star b may be habitable. 

2.) TRAPPIST-1d 


TRAPPIST-1d was detected with the transit method. The density of TRAPPIST-1d indicates a manily rocky composition. TRAPPIST-1d is a closely orbiting planet which takes only 4.05 days (about 97 hours) to complete one orbit. This exoplanet is one of the most Earth-like planets. It does not have a hydrogen or helium-based atmosphere, which makes largest planets uninhabitable. Its host star TRAPPIST-1 is some 40 light years away.

3.) Kepler-1649c


This is an Earth-sized exoplanet, likely rocky. It was discovered by the Kepler spacecraft on 15 April 2020 by the transit method. It takes about 19.53 days in orbiting its host star Kepler-1649. It may be tidally locked. As of 2021, no solar flare-ups have yet been observed from its host star. It receives 75% of the light from its host star that the Earth receives from the Sun.

4.) Proxima Centauri b


This planet orbits in the habitable zone of its host star Proxima Centauri, the closest star to the Sun. Proxima Centauri b is the closest exoplanet to the Earth. Proxima Centauri itself may have been captured by Alpha Centauri and thus is not necessarily of the same age as the Alpha Centauri. Proxima Centauri b is likely to be tidally locked to its host star.

What is soundproofing and carbon dating?

 1.) how a room is made Soundproof? Ans- You must have heard of soundproof rooms. Sound travels in the form of waves. Sound waves can travel through air, water and even solid materials like glass. Sound waves get weaker as they move away from the source. Glass windowpane is too thin to resist sound but two panes put 20 centimeters apart weaken the sound greatly. Soft materials like heavy curtains absorb sound and make the room soundproof. To make the recording rooms of studios soundproof, the walls are constructed without windows but with holes. The walls and ceiling are also lined with sound absorbing panels made of cork, foam etc. 2.) what is carbon dating? Human’s natural curiosity about knowing the age of different organisms that once lived on Earth resulted in the technique of Carbon Dating. The ages of different age-old plants and animals can be determined through the Carbon Dating process. Some other names of this technique are Radiocarbon and Carbon-14 Dating. Like all mate...

DO YOU KNOW THESE THINGS ABOUT PLANES AND JETS?

1.) Can planes take off and land vertically? Answer to this is YES. One of the most exciting development in aircraft technology is the VTOL (Vertical take-off and landing) planes. The most successful aircraft of this type is the British-made Harrier Jump Jet. The normal twin-jet aircraft have have the jet engines fixed at the sides of the aircraft or to the wings but Single Jet-Engined Aircrafts have the engine built in its fuselage. Both the aircrafts suck-in air from the front and mix it with the fuel in the Compression-Chamber, then the Exhaust Gases are ejected from the rear which thrusts the aircraft forward. The engines in the VTOL aircrafts can be repositioned vertically and the exhaust is directed downwards and the aircraft is thrusted upwards. VTOL Aircrafts are mainly used for military purposes. Long runways are not needed for the Take-Off and Landing of VTOL Aircrafts. Once in air they can fly at supersonic speeds. The Harrier Jump Jet. 2.) How does Autopilot mode works? Aut...

ANCIENT EGYPTIAN MEDICATIONS, WAY OF TREATMENTS, SURGERIES ETC.

 INFLUENCES  Ancient Egyptian civilization was a civilization that lasted from 3300-525 B.C.E.  Approximately, this is the time where the concept of health started. Some of the earliest treatments come from ancient Egypt. The ancient Egyptians thought that Gods, demons and spirits had a hand in causing diseases. The point that these people had systems of letters and numbers meant that they were able to record and develop calculations. Its best example is ancient Egyptian medical Literature which accounts for the oldest existence today. These people had an organized economy, system of government, a settled population, social conventions and properly enforced laws . Before that these people lived a nomadic life. This situation allowed their medical research to develop. For instance, there were wealthy individuals in the ancient society. They could afford the education fee and some healthcare which led to the development of this subject. The ancient Egyptians travelled long ...
