Mars is the fourth planet from the  Sun  and is the second smallest planet in the solar system. Named after the Roman god of war, Mars is also often described as the “Red Planet” due to its reddish appearance. Mars is a  terrestrial planet  with a thin atmosphere composed primarily of carbon dioxide. Mars Planet Profile Equatorial Diameter: 6,792 km Polar Diameter: 6,752 km Mass: 6.42 x 10^23 kg (10.7% Earth) Moons: 2 ( Phobos  &  Deimos ) Orbit Distance: 227,943,824 km (1.52 AU) Orbit Period: 687 days (1.9 years) Surface Temperature: -153 to 20 °C First Record: 2nd millennium BC Recorded By: Egyptian astronomers Mars Diagrams Mars  size compared to  Earth Mars  distance from the  Sun  and orbital eccentricity Facts about Mars Mars and Earth have approximately the same landmass. Even though Mars has only 15% of the  Earth’s  volume and just over 10% of the Earth’s mass, around two thirds of the Earth’s surface is covered in water. Martian surface gravity is only 37% of the Earth’s

The contribution of Physics in unraveling mysteries of the universe and its constituents has been tremendous and greatly remarkable. Discoveries made by the Physicists over the years have helped us a great deal in understanding both micro and macro cosmos. The discoveries, such as Planck’s constant and natural unit of light, have opened the Pandora’s Box around us to reveal other facts as well. Here is a list of top 10 mind blowing facts about Physics that will literally surprise you. 10. Light waves don’t always move in straight lines: It is generally believed that light waves only move in straight lines. However, as per the recent research in 2010 using computer controlled hologram, it has been proved that light, too, can get twisted into knots. According to the study, when light passes through the hologram, it twists into different shapes, producing multiple knots. 9. Unbelievable hydrogen energy: It is estimated that Sun burns around 620 million metric tons of hydrogen/second into

We use mathematics in everyday life. Therefore, it is not accidental that it is called the king of all sciences. Numbers are everywhere and we cannot imagine our world without them. 15 interesting facts about mathematics The first woman engaged in mathematics was  Hypatia  from Alexandria. Equal sign  invented in 1557 by Robert Recorde. If you add numbers from 1 to 100, you get 5050. Residents of Taipei are officially allowed not to use the number four (4), because it is considered to be “unlucky number”, and its meaning incorporated with the word “death”. Therefore, there are many buildings with no 4th floor, and after the third one, there is a 5th floor. Muslim mathematician  Al-Khwarizmi  is considered to be “the Father of Algebra” Despite the fact that many educated people lived in the Roman Empire, there was no number 0 in their mathematics. It is hard to imagine how they managed their life without the number 0 (zero) You may have already heard this story somewhere before. George
