Problem Writing Party February 15th - 28th - Andrew Ellinor

Hello Brilliant!

Brilliant's second Problem Writing Party was an even bigger success than the first. Thanks to all the contributions from Worranat, Brian, Anish, Arjen, Rajdeep, Nihar, Hobart, Jason, Pranshu, Margaret, Akshay, Lee, Jonas, Zeeshan, W Rose, Vignesh, Yash, John Michael, Sahil, Denton, Ishan, Sachin, and the countless others of you who helped!

This week, we were able to create a record-setting six new quizzes. Here are the quizzes that you all helped create:

New Brilliant Challenge Quizzes
Rational Functions: Level 2-3
Volume: Level 1
Volume: Level 2
Conservation of Energy: Level 2
Complexity / Runtime Analysis: Level 3
Limits of Functions: Level 1-2

As always, we're going to continue showing off the hard work these members of the community put in over the last week, so Brilliant will featuring these quizzes in topic listings and social media. Now that those announcements have been made, we're moving on to our third Problem Writing Party!

How it Works

The party starts right now (February 15th, 2016) and will last for the next two weeks. Throughout the two weeks, we will be focusing on writing awesome problems for the topics listed in quizzes that need your help on the publish page.

To join, submit as many problems as you want to these listed topics. At the end of the party, Brilliant staff will be picking the best 5-10 problems for each topic. These problems will then be immortalized and formed into a challenge quiz. If we pick your problem, then you can brag to your friends because it will be displayed on Brilliant forever!

Use this note to

Ask questions about the party or brainstorming ideas from Brilliant staff.

Share links to great relevant problems.

Bounce your ideas off each other to help formulate the best problem you can.

To be selected, problems you submit should be fun and challenging to a student in levels 1-3 for the given topic.

This Party's Topic Listing

The topics of problem submission for this party can be found by navigating over to the Brilliant publish page and checking under the quizzes that need your help section. Just click the contribute button next to the topic you want make a submission to.

Happy writing and continue to party on!

Easy Math Editor

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

Hello,nice to see such great events taking place in the community.I'm joining the party :)

Conical hemisphere

Logging inequalities

You can't resist solving this!

Branched resistance

A sphere and a cube

Logging inequalities 2

Logging inequalities 3

Happy solving!

Rohit Udaiwal - 5 years, 3 months ago

Whoa this is a lot of problems! Logging inequalities 2 makes me want to cry, but I can see putting logging inequalities 3 in a challenge quiz. ;)

Andrew Ellinor - 5 years, 3 months ago

Yeah,Logging inequalities 2 seemed unsuitable for a level 3 challenge quiz so I posted Logging inequalities 3.Thanks for selecting it :-)

I have a problem involving resistors. This is an old one, though.

Efren Medallo - 5 years, 3 months ago

Whoa this looks really hard! I'll be sure it goes in a difficult resistors quiz. Thanks! Keep throwing your fun resistors questions here (easy or hard).

Thank you!

Wow. Good News @Andrew Ellinor $:)$

Here are my $3$ new questions for Surface Area. Will definitely add more in due course of time.

1) Percentage Increase

2) Cuboid cut into cubes

3) Cube Surface Area Increase

These awesome graphics always add value to a problem. I know I'll be picking at least one of these (or maybe all three). Thanks Vighnesh!
