David and Kaori visit the Mikimoto Pearl Farm and see the 100-year process of culturing pearls. David and Kanae Nishio go wading in a forest stream, hunting for a giant salamander. This information supplied by Chuck N. Thank you, Chuck.

Impeding Japanese throughout is the erosion of Mmighty .t Fuji. David sees what steps are being guarded to help the Japanese society in spite of it. Included is a building where rainstorms and landslides are simulated.

David and Kaori visit the Furutas, whose family has been making paper by hand for two centuries. They follow the Furutas as they make a batch of fine paper. David, Kaori, and Chizuru Ishizaka join a kite expert and test a kite designed to fly in little wind. This information supplied by Chuck N. Thank you, Chuck.

David and Kaori get a glimpse of architects designing buildings that can resist the force of some natural disasters.

How would you like to write your messages in a strictly-ordered way, knowing that one mistake could change the meaning of your sentence? It can happen in English, but it's easier to write Japanese wrong. David and Kaori visit a software researcher and test out software that is designed to read and identify handwritten Kanji characters. (David puts his skills to the test and fails.) David and Kaori also participate in a grueling judo workout, after which they learn about a computer that helps train judo students. Finally, Kaori shows David the next closest thing Japanese language has to the English alphabet.

Archaeologists are seen trying to demystify the Mayans, Egyptian mummies, and a prehistoric cave where flint was mined.

There are ""archaeologists"" in Arizona that are analyzing modern humans from samples of their trash! It's a far cry from the tools of ancient man, or so you would think.

This show observes owls in the wild and the ecosystems in a salt marsh.

In the centerpiece of this episode, a museum moves a large dinosaur exhibit into place.

Can you tell a pattern when you see it? A combination of new and recycled material shows all sorts of patterns in nature.

Basic architecture can be whittled down to beams and a sheet. This is seen through circus tents, the Hubert H. Humphrey Metrodome and other things.

The frame is vitally important to anything architectural. We see how animals make their perfectly-designed shelters, how the Japanese can join two boards without glue or nails, and find the traditional Kenya home.

How do you build the world's largest Gothic cathedral? It all comes down to using marble cut in certain ways. The arch and the buttress are featured in the ongoing construction of the Cathedral of St. John the Divine.

There is a branch of architectural science called ergonomics, which states how things are built to fit certain people. David Quinn sees if he can improve the ergonomics of a kitchen.

The shape and composition of architectural materials can prove vital for various reasons. The I-beam and the triangle brace are highlighted in this episode.

Hard to believe mice and rats are mammals, as are bats. But this program shows why rodents are classified this way.

Fur and hair are mammals' chief arsenal to stay warm. But what about sea otters?

This show witnesses the births of elephant seals and wildebeests. Also seen are young black bears and kangaroos.

Play is an important part of growing, as we see from watching babboons, chimpanzees, sheep dogs and even kids playing.

There is a price ecosystems pay when big animals are confined. This program shows the elephant, the rhinoceros and the tapir groping with spatial problems.

Models are used to test ideas before they become large-scale. A class of intermediate-school students go through modeling tactics in building a spring-driven car. We also see newsreel clips of models that produced both commonplace items and inventions that didn't pan out.

Models observed in this episode include those of Canadian ice shields, fast bicycles, and modern airplanes.

Surveyors are seen at work, as are schoolkids who devise a map of their own neighborhood.

Models are shown in museums and in the medical world.

Much of this program focuses on a zoo's constructing an uncannily accurate rain forest for its animals.
