To consider the space solar power concept requires an understanding of science, technology, engineering, math, energy, policy, environmental factors, and more. Space solar power is an engineering project on a scale that rivals the greatest in history. Students need to be informed and able to participate in the conversation.

This programme is about how plants gain their sustenance. Sunlight is one of the essential requirements if a seed is to germinate, and Attenborough highlights the cheese plant as an example whose young shoots head for the nearest tree trunk and then climb to the top of the forest canopy, developing its leaves en route. Using sunshine, air, water and a few minerals, the leaves are, in effect, the “factories” that produce food. However, some, such as the begonia, can thrive without much light.

To gain moisture, plants typically use their roots to probe underground. Trees pump water up pipes that run inside their trunks, and Attenborough observes that a sycamore can do this at the rate of 450 litres an hour — in total silence. Too much rainfall can clog up a leaf’s pores, and many have specially designed ‘gutters’ to cope with it. However, their biggest threat is from animals, and some require extreme methods of defence, such as spines, camouflage, or poison.

The first episode looks at how plants are able to move. The bramble is an aggressive example: it advances forcefully from side to side and, once settled on its course, there is little that can stand in its way. An altogether faster species is the birdcage plant, which inhabits Californian sand dunes. When its location becomes exposed, it shifts at great speed to another one with the assistance of wind — and it is this that allows many forms of vegetation to distribute their seeds. While not strictly a plant, the spores of fungi are also spread in a similar fashion. One of the most successful (and intricate) flowers to use the wind is the dandelion, whose seeds travel with the aid of ‘parachutes’. They are needed to travel miles away from their parents, who are too densely packed to allow any new arrivals. Trees have the advantage of height to send their seeds further, and the cottonwood is shown as a specialist in this regard. The humidity of the tropical rainforest creates transportation problems, and the liana is one plant whose seeds are aerodynamic ‘gliders’. Some, such as those of the sycamore, take the form of ‘helicopters’, while others, such as the squirting cucumber release their seeds by ‘exploding’. Water is also a widely used method of propulsion. However, most plants use living couriers, whether they be dogs, humans and other primates, ants or birds, etc., and to that end, they use colour and smell to signify when they are ripe for picking.

This is the story about very closed, very sole world located in one village in Macedonia. In this village, life is like a fairy-tale, almost as if it is lived in another time and space. People there look at life through their own eyes, very slowly accepting changes from the outside world, but not wanting to be part of it. They like to keep quiet about anything that does not fit into their fairy tale. The wishes, the fears, the fights, the secrets stay hidden behind the closed and high gates of the houses.

The Amish keep surprising their technology-programmed neighbors by keeping alive ways and beliefs that many modern Americans wish they could recapture. Mennonite historian John Ruth takes us sympathetically into the Amish mindset.

Dr. John A. Hostetler, author of The Amish Society, comments on the survival of an alternative to the kind of world we have made. As the Amish increase in numbers, some of them migrate from homesteads in Pennsylvania toward more open farmland. Those staying where the land is too crowded to farm have developed an amazing variety of cottage industries. But all such changes are made very carefully, in order not to sacrifice spiritual covenant and community for the sake of convenience.

Human beings are in contact with the universe only through their five senses. No one can reach the real “external world” by going beyond these senses. So, how can we know that this world is not different from what we perceive it to be? This film invites you to ponder on this important question. When you watch this film, you will see how mistaken the materialist philosophy is when it denies God by assuming that matter is absolute. This film is based on the book “Timelessness and the Reality of Fate

The Mojave- a landscape of extreme and fragile beauty- will encounter new challenges with the coming climate change. Desert field researchers tell the story in their words and share their experiences with us. Joshua trees, Bighorn sheep, pupfish, desert springs, and even the soil crust itself face new problems.

Chaos theory has a bad name, conjuring up images of unpredictable weather, economic crashes and science gone wrong. But there is a fascinating and hidden side to Chaos, one that scientists are only now beginning to understand.

It turns out that chaos theory answers a question that mankind has asked for millennia – how did we get here?

In this documentary, Professor Jim Al-Khalili sets out to uncover one of the great mysteries of science – how does a universe that starts off as dust end up with intelligent life? How does order emerge from disorder?

It’s a mindbending, counterintuitive and for many people a deeply troubling idea. But Professor Al-Khalili reveals the science behind much of beauty and structure in the natural world and discovers that far from it being magic or an act of God, it is in fact an intrinsic part of the laws of physics. Amazingly, it turns out that the mathematics of chaos can explain how and why the universe creates exquisite order and pattern.
