Explains that heat is really a form of motion, a form of kinetic energy and that it can be converted to other forms of energy and transferred through conduction, convection and radiation. Shows practical examples in which heat preserves lives and makes daily living more convenient.

A documentary of insect life in meadows and ponds, using incredible close-ups, slow motion, and time-lapse photography. It includes bees collecting nectar, ladybugs eating mites, snails mating, spiders wrapping their catch, a scarab beetle relentlessly pushing its ball of dung uphill, endless lines of caterpillars, an underwater spider creating an air bubble to live in, and a mosquito hatching.
When the Tanana River bridge was installed in Salcha, Alaska, the community worried about the levee's effects on fish wildlife. Salcha Elementary School, along with the help of Tanana Valley Watershed Association, conducted a 10-year scientific project with students to study the effects the levee had on Piledriver Slough. Tori Brannan - the filmmaker's mother - is a retired principal at Salcha Elementary and was the project's centerpiece. She shares her experiences with the project, the community, and how her daughter's involvement strengthened their relationship.
In today's climate debate, there is only one factor that cannot be calculated in climate models - humans. How can we nevertheless understand our role in the climate system and manage the crisis? Climate change is a complex global problem. Increasingly extreme weather events, rising sea levels, and more difficult living conditions - including for us humans - are already the order of the day. Global society has never faced such a complex challenge. For young people in particular, the frightening climate scenarios will be a reality in the future. For the global south, it is already today. To overcome this crisis, different perspectives are needed. "THE UNPREDICTABLE FACTOR" goes back to the origins of the German environmental movement, accompanies today's activists in the Rhineland in their fight against the coal industry and gives a voice to scientists from climate research, ethnology and psychology.
For more than 50 years, we’ve been unsuccessfully searching for any evidence of intelligent extraterrestrial life. But, the discovery of thousands of exoplanets has meant the hope of finding them is higher than ever. If any messages could eventually be decoded and answered in any far, far away star, it could radically transform our consciousness as species and our place in the universe. A message from the stars changes life on Earth… forever.
Documentary about humankind’s first walk on the moon with Apollo 11, NASA’s first test mission of Orion for beyond low-space orbit, and Mars 1, the upcoming first manned mission to the red planet.
In June of 2012, LeBron James, Dwyane Wade, Chris Bosh and the Miami Heat made good on a promise to deliver a championship to the basketball fans of South Florida. It seemed unlikely that they would ever be able to match the drama and the intensity of that title run in an encore performance. But this was no ordinary basketball team. From the opening night of the 2012-13 NBA season, the Heat were determined to prove that not only were they up for the daunting challenge to repeat as champs but they were also destined to become one of the most successful and celebrated teams in history. No one could have anticipated the breathtaking 27 game winning streak that would catapult the Miami Heat into one of the biggest stories of the year. And after sweeping the Milwaukee Bucks, dispatching the Chicago Bulls and outlasting the Indiana Pacers, Miami would take home their second consecutive title after an epic seven game series with the San Antonio Spurs.
An epic documentary film that sends nine scientists to extraordinary parts of the world to uncover unexpected answers to some of humanity’s biggest questions. How did life begin? What is time? What is consciousness? How much do we really know? By introducing researchers from diverse backgrounds for the first time, then dropping them into new, immersive field work they previously hadn’t tackled, the film pushes the boundaries of how science storytelling is approached. What emerges is a deeply human trip to the foundations of discovery and a powerful reminder that the unanswered questions are the most crucial ones to pose. Directed by Emmy-nominated and Peabody Award-winning filmmaker Ian Cheney and advised by world-renowned filmmaker Werner Herzog, The Most Unknown is an ambitious look at a side of science never before shown on screen.
Record high oil prices, global warming, and an insatiable demand for energy: these issues define our generation. The film exposes shocking connections between the auto industry, the oil industry, and the government, while exploring alternative energies such as solar, wind, electricity, and non-food-based biofuels.
Rat Brain is a documentary that highlights Dr. John D. Douglass and his team's research at Seattle Pacific University on chronic stress' neurological impact, striving to uncover its link to suicidal behavior. Their work navigates ethical dilemmas while aiming to showcase vital insights into mental health and suicide prevention.
The story of the early Canadian oil industry from its start in Petrolia and Oil Springs, Ontario, from about 1850 to 1900. Dramatic re-creations blend with archival photographs and diaries to tell the rags-to-riches-to-rags tale of a boom that went bust.
The film discusses the evolution and potential of using light waves, particularly coherent light, for communication. It highlights the development of lasers at Bell Telephone Laboratories, explaining how they produce a highly controlled and intense beam of light that could revolutionize communication. The film emphasizes the vast possibilities of lasers, including applications in telecommunications, surgery, and exploring the universe, suggesting that this technology represents a significant step in humanity's understanding and use of light.
Since World War II North Americans have invested much of their newfound wealth in suburbia. It has promised a sense of space, affordability, family life and upward mobility. As the population of suburban sprawl has exploded in the past 50 years Suburbia, and all it promises, has become the American Dream. But as we enter the 21st century, serious questions are beginning to emerge...
A documentary that looks at systemic sexism faced by women scientists in STEM fields.
It is happening all across America-rural landowners wake up one day to find a lucrative offer from an energy company wanting to lease their property. Reason? The company hopes to tap into a reservoir dubbed the "Saudi Arabia of natural gas." Halliburton developed a way to get the gas out of the ground-a hydraulic drilling process called "fracking"-and suddenly America finds itself on the precipice of becoming an energy superpower.
How can we prevent epidemics? Why do viruses and bacteria move? Rather than trying to contain epidemics one after another, why not stop the processes that encourage their emergence? The challenges are enormous, but scientists argue that solutions exist. Because if emerging diseases are the collateral consequences of our lifestyles, our lifestyles are under our control.

Oil is a primary energy source in the world. Global oil consumption reached approximately 95 million barrels per day but oil fields' quality is constantly declining. A team of Russian scientists came up with more accurate, cheaper, and faster technology that can increase the oil production rate. After all, modern civilization is built in the way that 'to live well' means 'consume more oil'
