At TEDxRainier, Patricia Kuhl shares astonishing findings about how babies learn one language over another -- by listening to the humans around them and "taking statistics" on the sounds they need to know.

Clever lab experiments (and brain scans) show how 6-month-old babies use sophisticated reasoning to understand their world.

Patricia Kuhl studies how we learn language as babies, looking at the ways our brains form around language acquisition.

Patricia Kuhl is co-director of the Institute for Brain and Learning Sciences at the University of Washington.

She's internationally recognized for her research on early language and brain development, and studies that show how young children learn.

Former journalist turned online media powerhouse, Sue Gardner is the Executive Director of the Wikimedia Foundation, the non-profit organization behind Wikipedia, the online encyclopedia.

Before joining the Wikimedia Foundation, she ran CBC.CA, the website for the Canadian Broadcasting Corporation, one of Canada’s most prominent and best-loved cultural institutions (and one of my personal favorites).

I was especially interested in Gardner's talk as I am a HUGE fan and regular supporter of Wikipedia, without which Amazing Women Rock would not be the site it is today.

In this informal interview, Gardner explains how Wikipedia depends on the generosity of "strangers" to stay afloat:
