• Adding categories should not be done without due consideration. The structure of the wiki is supposed to be very definite and "new categories" should not be created without contacting the admins of the wiki. Existing categories can be added to the existing or new pages.

### 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.

### Big bang

TheBig Bang is the expansion of the Universe from an extremely hot and dense state that started about 13.7 billion ago.

### Gas

Gas is one of the four basic states of matter. A pure gas consists of individual molecules(like helium, xenon, neon, etc), diatomic molecules (like oxygen, sulphur, hydrogen, etc) or a compound molecule made of different atoms(as in CO2). 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

A small, soft space rock smacked into Costa Rica on April 23, 2019. And it may have carried building blocks for life. The washing machine-sized clay fireball broke up before landing, . Locals found shards scattered between two villages, La Palmera and Aguas Zarcas. And while meteorites turn up all over Earth, these shards were special; the asteroid that spawned them was a soft remnant of the early solar system, made from the dust from the spinning nebula that would ultimately form our solar system, formed in even older stars. This particular space rock contains complex carbon compounds, likely including amino acids (which join to form proteins and DNA) and perhaps other, even more complex building blocks of life.

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.
