Rick Dirks is one of the best tree climbers in California. He is able to climb 100-meter tall (328-foot) redwood trees with skill and courage and do so at breathtaking speed. He even ties himself to the crown of these giant trees in a sleeping bag for the night. In addition to trimming the trees and installing measuring tools, Rick collects the tree’s cones and seeds at dizzying heights – because the redwoods can only continue to survive if they are cultivated. In California, these giant trees are still cut down for timber.

The international scientific community is called on to take sides and provide solid answers. "Surrounded by Waves" explores the methods and motivations behind the most prominent research in the field and clarifies what we currently know, all with a mind to the social context behind the issue. Through an elegant blend of interviews, archives, experiments and 3D animation, the film clearly assesses the estimated risk linked to cell phones while offering a subtle observation of society's growing distrust of its industries and the unprecedented role of science in the debate.

THE INNER WORLDS. They orbit between us and our Star, the inner worlds; hidden within the sun's glare often only visible at sunrise or sunset. Venus the first and brightest star in the evening sky, and Mercury fleeting across the solar disk. They are half of our solar system's terrestrial planets yet we know so little. As we begin to take a closer look at our companions they are posing more questions than answers.

THE PLANET MAKERS. From the beginnings of our Solar System four and half billion years ago there remains tantalizing clues to its evolution; remnent debris: asteroids and comets. They vary in size from grains of dust to mountain sides, footballs to planetoids. They were the building blocks of the planets and perhaps carry the origins of life itself. Now within our grasp these rocks of ice and dust are ready to give up their secrets.

07: LA GOMERA. The European islands are renowned primarily for their hotel resorts. However, we will show you a completely different face of theirs: forests, beaches, coves, mountains, valleys and rivers. Perhaps you will find places that will take your breath away. Why just lie on the beach when there is so much to see? Put on some good hiking shoes, pull your shoelaces tight, and get to know the entire island like the back of your hand.

SALT LAKE CITY. Westward ho! We settle in Salt Lake City, where we learn about Bringham Young's settlement of the Utah territory and his monument at This is the Place Park. Then we dig in the dirt to find hundreds of perfectly preserved dinosaurs at the Utah Natural History museum. We'll take a look at some US aviation history at the Hill Air force Base museum, and see how life was like for the Utah pioneers at Frontier Homestead State Park.

TORONTO. TTH heads to the great white North…kind of. We visit the world class city of Toronto. There we'll head straight up the Western Hemisphere's tallest structure, the CN Tower. Next we score a look at the Hockey Hall of Fame and see a North American castle at Casa Loma. Finally we see how the British defended their city against the newly formed United States at Fort York.

S1 EP 09: WHITBY HALL. Built in the early 1800s, Whitby Hall used to be an administrative center and now stands as a public park and arts center. It has never before been investigated, but staff have reported many noises and presences among them.

Nové archeologické nálezy, válečná vyprávění z první ruky, rozhovory s odborníky a CGI a 3D rekonstrukce se prolínají v tomto investigativním pořadu, jenž se snaží odhalit skryté stopy těch nejpodstatnějších válečných událostí. Jednotlivá bojiště se stávají otevřenou knihou, která přináší nečekané prvky a detaily a prezentuje konflikty a jejich kontext ve zcela novém světle.(Viasat)

On 28 May 1940, while the Wehrmacht crushed the allied armies in France, British officials are prepared to deal with Hitler. They even suggest a mediation from Mussolini. Alone against all in the war cabinet, Churchill, by his cleverness and willingness, finally convinced his collaborators to fight.

SENSORY TRICKS. Seg 1 Visually-Evoked Auditory Response. VEAR or Visually Evoked Auditory response is the type of auditory perception where our brains perceive to hear sounds in response to seeing something. In the case of the jumping pylon illusion, a thud sound is perceived even though there is no sound accompanying the animation. Seg 2 Retinal Fatigue. Retinal fatigue is the term used to describe the condition when the photoreceptors in our eyes become tired or strained due to staring at one color for extend periods of time. The effect causes an afterimage of the complementary color to appear out of nowhere and will be temporarily visible for a few seconds. Seg 3 Müller-Lyer illusion. The Müller-Lyer illusion is an optical illusion where parallel lines of the same length appear longer when perceived with different pointed arrowheads drawn at the ends. Possible explanations suggest that our minds tend to look at overall length rather than just the line’s parts or segments when processing the image. Another possible explanation is that our minds tendency to look at angled lines and perceive patterns of depth. Seg 4 Ames Room. The Ames room is a specially constructed room that features a distorted and skewed floor plan. when viewed from one angle, our brain is tricked into thinking that the perspective of the rooms is normal but when a person walks from one end to another the distorted floor angle makes it look as if the person changes size drastically. Seg 5 Synesthesia. Synesthesia is a genetic condition that is present in at least 4% of the human population. People with synesthesia have hyper connected neurons that allow them to perceive a stimuli as interconnected with different senses. An example of which is the ability to see color while hearing sounds.

EP. 4. It’s the biggest museum in the world…the museum of artworks stolen over the centuries and never rediscovered. These works haunt the nightmares of their owners, and occupy the days of hundreds of police officers across the world, as well as those of a handful of private agencies; no country or museum of importance can claim to have been spared. According to Interpol, art theft is the fourth largest criminal trade, after the drug trade, the weapons trade and money laundering. How could it be otherwise, when the soaring price of art propels the value of some paintings into the tens of millions of Euros? This world appears to be full of mysteries. Crime syndicates rub shoulders with petty criminals and the police care more about recovering the items than they do about arresting the perpetrators.

In contrast with popular belief, Edison did not invent the light bulb. Many people contributed to the invention. Mind you, the first lamp was invented around 70,000 BC. Once upon a time we had limelight, which was actually quite unsafe, and then there were arc “arc lamps” – shedding light that blinded movie stars up to the point where they had to wear sunglasses. What Edison did was improve the light bulb to become a practical, affordable and safe product. He tested over 5000 filaments to make the bulb last: from bamboo fiber to a hair out of an assistant’s beard. At the same time others were working on light bulbs made with gasses, which we now know as energy efficient lamps. Modern-day lighting innovations are quite startling, a lot of them - we can’t even see with the naked eye… Lasers, for example. For the longest time it was merely a pet-theory of the grand Einstein. Nobody knew what to make of this idea that ‘atoms could release their excess energy as light’ When the laser was invented, people joked that the laser was ‘a solution looking for a problem’. Now it is omnipresent. In the near future: laser-light therapy by flashing the human brain.

EP. 02. On the plains of East Africa an epic journey is underway. Millions of wildebeest and thousands of zebras march in an annual, circular migration in search of lush grazing.Two major rivers, the Mara and the Grumeti, intersect their route and force the herds to cross. Crocodiles, the biggest living on earth, wait in these rivers to take advantage of this moving feast. In this ever-changing waterscape successful predators adapt their hunting strategies to suit the shifting environment.On the Grumeti River, DC is the Dominant Croc of a lose gang called the RagTags. When the wildebeest arrive to drink, these Pit Stops, Zone 1, are the crocs’ first challenge. It doesn’t go well for the RagTags. These smaller, inexperienced crocs don’t calculate their launch speed correctly, so opportunities are missed. DC finds a pool where he can work alone. He grabs an impressive male zebra, but the pool’s not deep enough to drown it. The zebra fights hard and DC is forced to let it go.Deep Water, Zone 2, is a zone exclusive to the Mara River. Steep banks and fast-flowing water make it a river that favours the crocodiles. Wildebeest plunge off the cliffs straight into the deep channel. To hunt here is easy: Swim, launch and drown.There’s no free lunch on the Grumeti. DC waits for the next opportunity. He picks up vibrations in the water that tell him the herds have started to cross. Zone 3, The Shallows, is a dangerous zone for crocodiles. Wildebeest gallop across the river and crocodiles can get trampled. DC captures a calf but the RagTags share with him and DC is left with a single mouthful. Frustrated with his small portion, DC drives the gang away. Theft is a viable strategy in the Grumeti. The RagTags follow DC when he tries to hoard his next prize. When DC spots one of the gang members and gives chase, the RagTags move in and steal the carcass.DC finds another opportunity on the Rocks, Zone 4. Wildebeest are forced to walk slowly to avoid tripping and falling. DC causes panic in the ranks and grabs a calf.This time he won’t share. He flicks the calf until the head tears right off the neck. Exhausted from the hunt, DC is forced to rest and recharge. He’s not alone. This pool belongs to a hippopotamus. Luckily the hippo is more curious that confrontational and he leaves DC alone. As the season moves on, the Grumeti River dries up. Only the tail-enders of the herd remain and DC needs one last kill before the herds disappear for good.On the Mara River the water itself is so treacherous that many animals die while crossing. Carcasses pile up on the riverbank, and the crocs here can scavenge long after the wildebeest have left. DC will have to hunt if he wants a stockpile. When the herds unexpectedly drink at the hippo pool, DC sets up for a Pit Stop attack. But suddenly they start to cross and it becomes a Rock Crossing!Wildebeest trample over him but he strikes a big wildebeest bull and holds tight. The hippo pool is not deep enough for a quick death. But DC outlasts the wildebeest in the tug-of-war. The Mara and Grumeti are two very different hunting grounds that require unique skillsets from the crocodiles. In both these trenches the predators responded to the nuances of the landscape and triumphed. At the Pit Stops and Rocks, in Deep and Shallow Water they learned to modify their hunting techniques – and thrived. And next year, when the herds return, these quiet waters will once again transform into Predator Zones.

This report shows how the famous Japanese green tea is cultivated, explores its healing power and explains how deeply the tea has penetrated Japanese society. For the Japanese people, green tea is more than just an ordinary beverage. It is the key to the national culture - it combines enjoyment, philosophy and the art of living. In springtime, the entire country waits for the first flush, the very first harvest of the precious Sencha tea from the island of Kyushu, the world's biggest organic tea production region.

NAGALAND. High in the eastern mountains in a remote corner of India, Soumik encounters the Naga tribes. They teach him about their mysterious customs, chicken dances and head-hunting traditions, part of a unique identity at the brink of extinction. The Nagas wish to preserve.

VARANASI. In the world’s oldest city of Varanasi, Soumik explores a neighbourhood that has produced five generations of Indian classical masters. He meets widowed women singers who have committed their lives to the Hindu God, Shiva, and a young drummer with the talent to make it big. Dedication to fading classical arts is formidable in this timeless city of religion, tradition and rising commercial interests.

ALASKA BOUND FROM PRINCE RUPERT. Running the Portland Canal from Prince Rupert to Alaska...and fishing Alaskan Halibut!

PRINCE RUPERT TO HARTLEY BAY. Trolling for Chinook Salmon in Prince Rupert then making big run Southbound to Hartley Bay through Grenville Channel!

NATURE'S GAMES. Seg 1 Carrion flowers. Carrion flowers are the unorthodox perception of flowers for they are rare, big, and very unpleasant. Other terms are stink flowers and corpse flowers. The biggest flower in the world, rafflesia arnoldii, is a carrion flower. These flowers are difficult to find and reproduce and could breed through cross-pollination by attracting flies and dung beetles. Seg 2 Aposematism. Aposematism is a form of signalling that enables protection for both preys and predators by giving signs of poison and danger through showing off the bright colors and patterns on their epidermal layers that become associated with inedibility. Some species have developed mimicry based on aposematism in order to avail the protection aposematic colors give. Seg 3 Cuckoo Misdirection. Cuckoo misdirection demonstrates the mimicking abilities of a female cuckoo in order to find host nests to hatch her eggs. The female mimics a cry of a predator bird in order to frighten the hosts, leaving them vulnerable, thus the cuckoo can seize the chance to drop her egg on a host nest. Seg 4 Pheromones. Animal pheromones are the chemicals secreted and released by different species to communicate with other organisms. There are various types serving different purposes, ranging from reproduction, to trailing, to alarms. Some pheromones are also specific to one species of animals. Seg 5 Deimatic Behavior. Deimatic behavior is another type of defensive behavior in animals that also involves mimicry. It’s the opposite of aposematism because while aposematism works by blatantly showing or signalling its danger or unpalatability, deimatic behavior relies on the element of surprise to startle predators in order for species to flee to safety.

JOHANNESBURG: CITY OF MANY FACES. From the streets of Soweto to the colonial Union Building, the metro area of Joburg is a mix of architecture, people and traditions. Johannesburg is more than just a big city—it’s also home to one of the world’s best safari parks.

KRUGER NATL PARK: HUNT FOR THE CHEETAH. In all previous Journeys’ shows, only glimpses of the cheetah were seen. Here at Kruger, we get up close to this shy cat before heading out of the park and visiting a special research and breeding center dedicated to cheetahs.
