### Open Science Wiki

OpenScience is a community effort by students to bring conceptual explanation and detailed information about various topics in the various fields of science. Students will share their knowledge, research, and ideas about scientific discoveries and the workings of nature as we know it. This wiki will have sections for broader science areas like biology, chemistry, and physics, which will be stubdivided by concept/topic groups. The goal of this wiki is not only to be a repository of scientific knowledge, but also to provide explanations and even lessons such that students can learn about interesting topics outside of the classroom in a way that is coherent and understandable.

A mixture of gases contains variety of gaseous molecules like that of air. Read More>>

### Gravitational Force

Gravitational Force is an attraction between two bodies by the virtue of their mass. The force of attraction between two point masses is $F = G \frac{m_1 m_2}{r^2}$, where m1 and m2 are the masses of the particles and r is the distance between them. G is a universal constant having the value 6.67 × 10-11 Nm2kg-2. Read More>>

Image of The Week

India's first mission to Mars has captured a stunning new 3D view of a vast chasm, revealing gullies shaped by erosive forces on the Red Planet. The images, sent back by India's Mars Orbiter Mission (MOM), show Ophir Chasma, a portion of the massive Valles Marineris system that stretches across much of the planet's equator. The images were taken July 19 and have a resolution of about 315 feet (96 meters). The new images show the chasm from above and two different views of the sides, revealing hills, small impact craters and gullies shaped by landslides.

Search the Elements

On the right hand side is the crossword puzzle. There are elements from the periodic table which are spread in all the directions(horizontal, vertical and diagonal). The answer for this puzzle is hidden on our wiki if you dare then try to search the wiki for the answers: it's not so hard though.

We prefer that you open the full sized image as it would be more easy to view.
