Jeremy Kasdin: The flower-shaped starshade that might help us detect Earth-like planets

​Don't forget there are some excellent TED talks on your computer, tablet, smart phone or smart tv.​

06:38 minutes · Filmed Mar 2014 · Posted Apr 2014 · TED2014

Astronomers believe that every star in the galaxy has a planet, one fifth of which might harbor life. Only we haven't seen any of them -- yet. Jeremy Kasdin and his team are looking to change that with the design and engineering of an extraordinary piece of equipment: a flower petal-shaped "starshade" that allows a telescope to photograph planets from 50,000 kilometers away. It is, he says, the "coolest possible science."

The parenting section of the bookstore is overwhelming—it's "a giant, candy-colored monument to our collective panic," as writer Jennifer Senior puts it. Why is parenthood filled with so much anxiety? Because the goal of modern, middle-class parents—to raise happy children—is so elusive. In this honest talk, she offers some kinder and more achievable aims. Watch »

Puberty is an awkward time for just about everybody, but for transgender teens it can be a nightmare, as they grow overnight into bodies they aren't comfortable with. In a heartfelt talk, endocrinologist Norman Spack tells a personal story of how he became one of the few doctors in the US to treat minors with hormone replacement therapy. By staving off the effects of puberty, Spack gives trans teens the time they need. Watch »

Pick up a book, magazine or screen, and more than likely you'll come across some typography designed by Matthew Carter. In this charming talk, the man behind typefaces such as Verdana, Georgia and Bell Centennial (designed just for phone books -- remember them?), takes us on a spin through a career focused on the very last pixel of each letter of a font. Watch »

Within each of us are two selves, suggests David Brooks in this meditative short talk: the self who craves success, who builds a résumé, and the self who seeks connection, community, love -- the values that make for a great eulogy. (Joseph Soloveitchik has called these selves "Adam I" and "Adam II.") Brooks asks: Can we balance these two selves? Watch »

"

[We tend to think] if you add Democrats, you add Republicans, you've got the American people. But that is not the case at all. … The largest block, 40 percent, say they're independents."

Norman Spack: How I help transgender teens become who they want to be
  Dealing with your own gender and sexual identity can be hard enough when you're in your teens. But later, seeing your child trying to cope with a different gender or sexual identity of which they are increasingly sure but don't know how to bring out and about can leave you in a powerless pain, like watching someone drown out of your reach.

Dr. Spack goes the whole way, which saves lives, but equally important he creates space for society to understand alternative gender identity. Societal hormone treatment if you like. I love that. Thank you for doing what you do."
