Fresnel and the Lighthouse
June 04, 2014
Shipwrecks abounded in the early 1800's; in fact, over 100 ships wrecked in the English Channel in 1816 alone. So a physicist developed a new type of lens that dramatically increased the range of lighthouses - and the safety of sailors. This is his story.

Cheetah Physics
June 19, 2013
A new study shows that while cheetahs are still the fastest land
animal on Earth, it's not their speed that makes the great hunters;
it's their acceleration. What's the difference? For that we turn to

building with nothing but a breath of air? Find out how on this week's podcast.

Let's go ride a bike
November 28, 2012
Between 1860 and 1885, cyclists who wanted both efficiency and speed
rode what we now call "penny farthings," or bicycles with front wheels
as large at five feet in diameter. Why the big wheels? And why don't
we have bikes like those anymore? The answer, as you might suspect,
involves physics.

Whale Flipper Bumps
October 02, 2008
Why are humpback whales more agile in the water than other whales? Scientists discovered that the bumps on humpback flippers decrease water turbulence. This allows the humpback whales to tilt their flippers up  and achieve greater lift over other whales and hence gives more maneuverability.
