Sound is...
From Bishop Sand | Part of the Sound series | 14:39
What is sound? We'll define it physically and through our experience. Interesting descriptions abound as we learn why a piano sound is different than a violin sound alongside a small description of human echolocation.
This is the first installment of our series about the information found in sound.

A fetus begins to respond to sound at 18 weeks old. We are bathed in sound every day of our lives and yet it isn't clear what exactly the phenomenon is because it isn't as visible as, say, light. In this small episode we dissect the outward physical description of sound and also touch on the main aspects of the subjective perception of sound. Learn why instruments and voices are recognizable and why we can learn to echolocate.
This is the first piece in a series about the information found in sound. Contributors to this piece and the others in the series:

Engineering Change: Why STEM matters
From With Good Reason | Part of the With Good Reason: Weekly Half Hour Long Episodes series | 28:59
Science, Technology, Engineering, and Math. Why does STEM matter, and why are women and minorities being targeted? This is the first in a series taking a close look at STEM education in America.

- With Good Reason
American students rank 21st out of 30 developed nations in science literacy and 25th in math literacy. To boost performance in science, technology, engineering, and math (STEM), the White House has launched an “Educate to Innovate” campaign, and it even held the first White House Science Fair. In this series on STEM education in America, With Good Reason is asking national policy experts, educators, and innovators why STEM matters and why women and minorities are being targeted. We talk with the head of Change the Equation, a nonprofit dedicated to getting businesses involved in STEM education; a science education historian on America's past efforts to encourage more math and science in schools; a scientist who says we have to break stereotypes; and a professor on the orgins of the acronym S-T-E-M.
Edna the Engineer and National Security

A recent science test showing that American girls are lagging behind boys has brought women in science back into the national conversation. More than 50 years ago, one group of engineers argued that training girls in scientific fields is not just about equality; it’s about the fate of our nation. Allison Quantz has this story.

International Testing in Science and Math
From With Good Reason | Part of the news features series | 02:31
In response to international tests that show American students lagging, a number of programs supporting the study of science, technology, engineering, and math have been launched. But how accurate are those tests, and why don’t our students fare better? Sandy Hausman has the story.

At the Pratt Institute in Brooklyn, one of America's last working steam engines is firing up. Until just a few years ago, it was used to generate electricity for the school. These days, it's mostly run for visitors to see -- and for the annual New Year's Eve party. The rest of the year, one man lovingly tends to it: Conrad Milster.

Somewhere in the midwest are two of the most unnatural sounding rooms in the world, which some say were used to test the hearing of rabbits.

For years George had been obsessed with the stories of two sound chambers on the campus of Indiana University in Bloomington. Known as 'acoustic test chambers' around the campus, the two rooms (at least in George's case) have been shrouded in mystery, rumor and intrigue. Recently included as part of the IU Department of Speech and Hearing Sciences, what are actually called the anechoic and echoic test chambers are now being used for sound localization research.
