# Wiki Weekend Party 18 - Chemistry, Logic and Physics!

Congrats on another successful Wiki Weekend Party. The Chemistry Wiki is coming along, and the community is actively collaborating on great pages. I’ve also been brainstorming with the community on #calculus, and we now have several comprehensive pages with numerous examples. We’ve seen how much people benefitted from getting feedback on their wiki pages through chat, and would be incorporating that much more. We’ve also been refining the concept of a wiki page, and have come up with the following:

What is a Brilliant wiki?
A Brilliant wiki has a brief overview of a topic, followed by tons of examples and applications. It should also have the following attributes:

• Engaging perspective The topic is introduced in a way that explains why a person should be interested.
• Illuminating examples Key concepts are illustrated through examples that build intuition and quickly convey a practical knowledge of how to solve common problems.
• Visual appeal The page is well-organized, easy to read, and integrates helpful images, GIFs, and videos.
• Interactivity The page contains quizzes and problems for the reader to try, to see if they understand the concepts and techniques in the wiki.

Brilliant wiki pages are written at the reading and comprehension level of an advanced high school student. For more details, see Wiki guidelines

This week, we will be working on Chemistry, Logic and Physics. More information is available here

Chemistry: Expansion into Organic Chemistry
Structural Representations of Organic Compounds
Common Names in Organic Chemistry
Chain Isomerism
Position Isomerism

Chemistry: Improve pages written up last week, pages begin with the description of what the thing is and include examples of the concept
Ionic Compounds - Needs supporting examples
Acid Base Equilibrium - Needs proper organization, needs more content
Atoms and Molecules - Needs examples, needs information on orbitals
Balancing Reactions - Needs explanation of N-factor in more detail, could use more examples

Logic:
Fill in the blanks
Operator Search - Trial and error, finding constraints / bounds
Tic Tac Toe - Explain the “double trap”, explain player 1 strategy, explain why it always end in a draw if both play optimally

Physics:
Momentum - Needs examples, explain how to calculate momentum and impulse
Moment of inertial - Explain how to calculate center of mass of several particles, needs examples, formatting could be improved

Chat with other editors to collaborate on these pages

What is the square root of i

- 2 years, 11 months ago

$$i=e^{\frac{iπ}{2}}$$

Therefore $$i^{\frac{1}{2}}=e^{\frac{iπ}{4}}$$

You may equate it to a+ib and then square the equation and compare real and imaginary parts. But more sweet and simple is to do what @aditya kumar did

$$\sqrt{i}$$

This is not a thread for asking doubts/question. If you want to do so , you can post a note or a problem. Thanks! :)

Dude if u couldn't solve it then just leave it as it is ...thank u ..

- 2 years, 11 months ago

I of course knew the answer , but do you think that this note has any relation with complex numbers?

- 2 years, 11 months ago

Of course it has .....try solving it ..i discussed it with many people but was unable to figure it out
