Super Sticky Gecko Adhesive
May 01, 2013
A material inspired by gecko toe pads might be the ideal
household adhesive: it can support hundreds of pounds but peels off
Destructive Domino Effect
January 31, 2013
Did you know that with the right set-up you could knock down a
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,
Dance your PhD
October 31, 2012
Today on the physics buzz podcast we talk with Diana Davis, winner of the Dance Your PhD contest in the physics division. Check out Davis' winning entry on our blog, then listen to Davis address misconceptions about math research, and the shape of our universe.
Ig Nobel Prizes
September 26, 2012
The physics of ponytails, the fluid dynamics of coffee cups and zombie fish are just some of the highlights from this year's annual Ig Nobel Prizes, celebrating science that makes you laugh, then makes you think.
July 25, 2012
Even though Hollywood films aren't known for being completely scientifically accurate all of the time, the writers of some of the biggest films and TV shows have been relying on their science advisors to make the science in science fiction all the more believable.
Who is Enrico Fermi?
July 18, 2012
Physicist Enrico Fermi has his name attached to a number of monumental physics items, like Fermilab, fermions and fermium. Who was Fermi, what did he do to earn so much notoriety and the title of "universal physicist"? We'll try to find out in today's podcast.
How the Hippies Saved Physics
July 04, 2012
Dr. David Kaiser, author of the book "How the Hippies Saved Physics"
talks about how the culture of the 1970's influenced physics, and
brought the philosophical exploration of quantum mechanics back into
June 13, 2012
A single sheet of paper is easy to tear, but why, then, do crumpled balls of newspaper work as cushioning in packing boxes? Physicists are studying this unique architecture that maximizes the inherent strength of paper.
Snakes and Bombs
March 14, 2012
Calla and Mike pay a visit to the APS March Meeting to learn about scientists studying slithering snakes and to discuss how magnetic fields are leading to better bomb detection.
December 07, 2011
Over billions of years, living creatures have evolved elegant solutions to complex engineering problems that humans are just starting to figure out. Fish and whales have developed ways to swim efficiently in the ocean, which researchers are now hoping to adapt for power generating wind turbines.
September 14, 2011
10 years after the towers fell the reflecting pools are about to open to commemorate this tragic event. Join Calla Cofield as she reflects on the physics of the falling towers and lessons for future presidents.

Inventor and former rodeo rider Stephen Wharton uses physics to measure the power of bucking bulls.
March 23, 2011
The carnivorous bladderwort is the fastest carnivorous plant known to
man. It achieves this awesome title with the power of physics.
The Cat Lap
February 03, 2011
After watching his own cat lapping up its breakfast one morning, MIT Engineer Roman Stocker wanted to know just how the cat moved liquid from the bowl to its mouth. The answer is unexpected, and it involves some interesting 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.
Back Flip Limit
September 04, 2008
Scientists have calculated that 4 back flips is the upper limit for a dare devil motorcyclist. The energy required for the height and rotation of 4 back flips is the maximum amount of energy that the motorcycle can produce.
