Happy International Women's Day 2015

"Today marks International Women’s Day, an annual event that celebrates women’s accomplishments and promotes global gender equality.

This year’s theme is ‘make it happen’ and aims to encourage effective action for advancing and recognizing women. It focuses on women in different professional sectors; the arts, female-owned businesses, in senior leadership roles, and all aspects of working environments where gender parity has still not been achieved.

Google has celebrated International Women’s Day with a doodle presenting women in high achieving roles as astronauts, scientists, athletes, teachers, musicians, chefs and writers – roles that were once reserved solely for men. It links out to a series of stories highlighting why such an event is still so crucial over a century after it was first launched. The doodle’s caption reads: “Happy International Women’s Day!’

The first International Women's Day was held in 1911 and is celebrated annually on 8 March with thousands of events across the world."

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.
