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.

Tests of the “Twin Paradox”

The featured article is more of a study than article The so-called “twin paradox” occurs when two clocks are synchronized, separated, and rejoined. If one clock remains in an inertial frame, then the other must be accelerated sometime during its journey, and it displays less elapsed proper time than the inertial clock. This is a “paradox” only in that it appears to be inconsistent but is not.Read More>>>

Grignard

This is the portrait of Victor Grignard, a Nobel-Prize winning French Chemist. He is most noted for devising a new method for generating carbon-carbon bonds using magnesium to couple ketones and alkyl halides. He had a strange start in academic life for a chemist- he took a maths degree. When he eventually switched to chemistry, it was not the mathematical province of physical chemistry but to organic chemistry. While attempting to find an efficient catalyst for the process of methylation, he noted that Zn in diethyl ether had been used for this purpose and wondered whether the Mg/ether combination might be successful. Grignard reagents were first reported in 1900 and Grignard used this work for his doctoral thesis in 1901. In 1910, Grignard obtained a professorship at the University of Nancy and in 1912, he was awarded the Nobel Prize for Chemistry which he shared with Paul Sabatier.


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.

Amazing Facts
Fact #1!Fact #2!Fact #3!Fact #4!
The poles on Uranus are warmer than the equator because its axis is tilted quite heavily!Above 4 °C, water expands when heated and contracts when cooled. But between 4 °C and 0 °C it does the opposite, contracting when heated and expanding when cooled. Stronger hydrogen and oxygen bonds are formed as the water crystallizes into ice. By the time it's frozen it takes up around 9% more space.The Central American salamander Bolitoglossa dofleini can extend its tongue more than half its body length in 7 milliseconds, 50 times faster than you can blink an eye .Seahorses don't have stomachs, just intestines for the absorption of nutrients from food. Food passes through their digestive system rapidly, so they eat plankton and small crustaceans almost constantly.
