smart happens. Hi, I'm Marshall Brain with today's question. When
I stand at the water's edge and look out over
the ocean, how far away is the horizon. One of
the funniest things about the ocean is the fact that
(00:43):
its surface is curved. We tend to think about water
forming large flat sheets, but the surface of a body
of water is not actually flat at all. It follows
the curvature of the Earth because of the curvature of
the planet. The distance between you and the horizon when
you look out over the ocean depends on your height
(01:03):
above the surface of the water. If your eyes are
eight inches above the water, the distance to the horizon
is about a mile. If you're six ft tall and
standing right at the water's edge, then your eyes are
about five and a half feet above the surface. The
distance to the horizon is about three miles in that case.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
