In this chapter, the scientists will try to find the best corn to make the biggest popcorn. They will also have a lot of fun with optical illusions. And finally they will show how eyeglasses gather light by using lasers. Part of the House of Science Series.

Bill Nye explores facts about the brain, zeroing in on some of its functions, kinds of memory, optical illusions, and general information. Suggests activities and experiments that demonstrate the wonder of the brain.
Most pet owners talk to their animals at one time or another, and some do every day. But, how much do pets actually understand? Is their perception anything like our own? These are the questions that fascinate Irene Pepperberg and she’s looking for answers from the animals themselves, specifically – African Grey Parrots. The Harvard psychology professor is a bit like the character Dr. Doolittle because she’s been talking to parrots for decades. With help from the National Science Foundation, she’s researching how much the birds understand about shapes, numbers, and colors. Her next phase of research involves how the parrots detect optical illusions, and whether they perceive them the way humans do. Her research will also reveal more about how a bird’s vision works.
Today's optoelectronic engineers are developing extremely thin glass that is both durable and scratch-resistant. Telecommunications systems require speed and accuracy, and glass is proving to be important in developing semiconductors, optical fibers, and multiplexing. Precisely engineered glass is also used in terrestrial and extra-terrestrial telescopes.
Gives a general introduction to microscopes, a device invented 400 years ago. Begins with a simple magnifying glass and moves to the optical, confocal, electron, scanning electron, and the scanning tunneling microscopes. Shows that each one "sees" with increasing detail. The microscope opens invisible worlds and aids scientists in improving ours.
This award-winning documentary on LIGO, NSF's Laser Interferometer Gravitational Wave Observatory, examines how LIGO is spearheading the new field of gravitational wave astronomy and opening a whole new window on the universe. LIGO's exquisitely sensitive instruments may ultimately take scientists farther back in time than ever before, catching, perhaps, the first murmurs of the universe in formation.
Imagine having the ability to manipulate light waves in order to see through a skull right into the brain, or being able to use lasers to diagnose a bacterial infection in a matter of minutes. At the Center for Biophotonic Sensors and Systems (CBSS) at Boston University, technologies enabling these abilities and many others are coming to light. With support from the National Science Foundation (NSF), mechanical engineer Thomas Bifano and his colleagues are developing optical microscopes that can image deep into biological tissue, helping scientists observe molecular-scale activity. Their goal is to revolutionize the diagnosis and treatment of disease. Part of the National Science Foundation Series “Science Nation.”
