New Points Exchange

Just wanted to say, I love the new Points Exchange.

#PointsExchange #Opinions

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.

We are glad you guy's like the new points exchange!

For the future, feel free to suggest books for the points exchange. You can do this by emailing me at discussions@brilliant.org, or creating a discussion to see if others are also interested in that book or genre. When you create a discussion for this, give your post the tags "points exchange" and "feature requests" and we will look into them. Our constraints on what we could potentially offer are: the book must be available in e-book, and it must not be outrageously expensive.

If you do not have a specific book in mind, but do know what kind of things you would like to read, tell us about what you would like to read and we will look around and see if there is a book that we could offer on that topic.

Harshit Kapur - 8 years, 4 months ago

I would prefer physical things instead of e books

Alan Liang - 8 years, 4 months ago

Imagine the cost of buying and shipping them to people across the world...

Ryan Soedjak - 8 years, 3 months ago

well yes. but perhaps something similar to the lanyards?

Alan Liang - 8 years, 3 months ago

I order a level 3 lanyard a week and a half before this.Will i receive it or not as now lanyard are only for level 4 and up.Any idea anyone?

Sridhar Thiagarajan - 8 years, 4 months ago

Sridhar, You will still receive your level three lanyard. All who claimed a lanyard below level 4 before the change in the points exchange will receive a lanyard. Please allow plenty of time for it to arrive, experience has shown us that it can take an extremely long time to reach India.

Peter Taylor Staff - 8 years, 4 months ago

it can take an extremely long time to reach India.

Lol! That seems pretty obvious to me considering the fact that a "Happy New Year 2012" card that my relative living in the USA sent, reached me in Jan 2013 :P (It actually happened so! )

Nishanth Hegde - 8 years, 4 months ago

you will receive level3 lanyard

Sri Venkata Vivek Dhulipala - 8 years, 4 months ago

Sure?How do you know bro?

Sridhar Thiagarajan - 8 years, 4 months ago

@Sridhar Thiagarajan – challenge masters will say the same thing

Sri Krishna Priya Dhulipala - 8 years, 4 months ago

I ordered a level 2 and level 3 lanyard a month ago, and still nothing has yet to arrive in my mailbox, and I live in the US.......

Wilson Ly - 8 years, 4 months ago

Wait for a Brilliant staff to reply to this comment..or try creating a discussion to bring it into their notice. Or try the 'Contact Us' link at the bottom of the page.

Nishanth Hegde - 8 years, 4 months ago

i don't understand what the lanyard exactly is .. could anyone tell me

Ahmed Thabet - 8 years, 4 months ago

@Ahmed Thabet – A lanyard is a rope or cord worn around the neck with a key ring at one end to hold things that you do not want to lose. Think of it as a useful necklace. That said you do not have to wear them around your neck, you can put them in your pocket and treat it as long keychain. People commonly attach their keys, flash drives, id cards, whistles, hand lens, pens etc...

Peter Taylor Staff - 8 years, 4 months ago

I'd ordered for the level 3 lanyard last week. Can anyone tell me how much time i.e. how many weeks or months (approx.) would it take before the lanyard arrives to me... ---( I am from India )

Kishlaya Jaiswal - 8 years, 3 months ago
