Galileo faces an uncertain future. Behind the scenes are political and religious intrigues and enemies plotting his downfall. The Pope, until now sympathetic to Galileo, has a change of heart. Under pressure from all sides and insulted by his latest works, The Dialogue Concerning the Two Chief World Systems, portraying the Church's view through the character Simplicio (Simpleton), the pope finally sends Galileo to the Inquisition Tribunal.

After the farm visit, it's time for our angora rabbit and goat breeder to show us around her boutique, where you can stock up on fluffy angora wool sweaters and super light and warm socks to help you enjoy the winter in comfort.

Galileo is under close scrutiny because of his Copernican views. Unfazed, he carries on his research and his teachings. Will the Inquisition bring his demise or will his powerful friends, Pope Urban VIII among them, protect him?

Galileo is about to throw caution to the wind and reveal his startling discoveries about planet Earth.

In the second episode of Ferme de la Croix de Pierre, the goat breeder gets all warm and cuddly with one of her baby goats, which become like plush toys when bottle-fed. She'll teach you all you need to know about caring for these adorable animals.

In part five of this episode on "The Discoverers," Galileo is warned. His belief that the Earth revolves around the sun is sacrilegious. Giordano Bruno, who claimed this fact, was burned as a heretic by the Inquisition Tribunal.

In part four of this episode on "The Discoverers," Galileo, now a reputable scholar at the University of Padua, proceeds to make a telescope out of lenses with the help of his instrument maker, Marc'Antonio. In this cartoon, an attempt is made to explain Galileo's discoveries.

Have you ever wondered where the wool from your luxurious angora sweater comes from? At the Ferme de la Croix, a lovely lady breeds angora rabbits and goats on her farm. She explains the shearing process and how she cares for her pets. We learn that one rabbit can yield forty balls of angora wool every hundred days. That's a lot of sweaters!

Episode nine of this series focuses on Galileo, a prolific inventor and scientist. He discovered the principle of the simple pendulum motion, very useful in the measure of time and later in the making of clocks.

In this video, a young Galileo gets one of his first revolutionary ideas on how to measure time. Pretty impressive for a fourteen-year-old, huh?

In this video, a representative at an ecology trade show presents some innovative building materials that are eco-friendly and will allow you to save some money on your energy bills. These materials are made out of gypsum cellulose and are used for insulation.

The Maestro explains how the revolutionary ideas of the early discoverers, which we now take for granted, were not always well received. Before Galileo, for example, everyone believed that the sun and all the other planets revolved around the earth!

In the last segment of this Il était une fois... episode on technology, we learn more about what vertical farms can do to help the planet thrive. The first commercial vertical farm recently opened in Singapore.

Our eco-friendly home show representative explains the benefits of cellulose wadding versus fiberglass, two insulation materials commonly used in houses.

The students present the Maestro with various solutions for eliminating pollution on our planet, including vertical farms and biotechnology.
