Metric System

Hi I'm new to Brilliant and I already subscribed for a year. I love it that there is finally a well made math & science website for learning. Today though, I got triggered here: https://brilliant.org/practice/exploring-ratios/?p=6

Science and most of the world does use the metric system, plus we lost one satilite or so because of a unit conversion mistake. Please do not use feet, inches or hands for messurements, use metric units. And if you can't let go of them, please make it chooseable in the options. It would be really strange for a science community to cling to outdated tools/units. Let's work together on one good standard.

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.
