Deeper, Deeper, Deeper Still

   2014    Science
This episodes the nature of the cosmos on the micro and atomic scales, using the Ship of the Imagination to explore these realms. Tyson describes some of the micro-organism that live within a dew drop, demonstrating parameciums and tardigrades. He proceeds to discuss how plants use photosynthesis via their chloroplasts to convert sunlight into chemical reactions that convert carbon dioxide and water into oxygen and energy-rich sugars. Tyson then discusses the nature of molecules and atoms and how they relate to the evolution of species. He uses the example set forth by Charles Darwin postulating the existence of the long-tongued Morgan's sphinx moth based on the nature of the comet orchid with pollen far within the flower. He further demonstrates that scents from flowers are used to trigger olfactory centers in the brain, stimulating the mind to threats as to aid in the survival of the species. Tyson narrates how Greek philosophers Thales and Democritus postulated that all matter was made up of combinations of atoms in a large number of configurations, and describes how carbon forms the basic building block for life on earth due to its unique chemical nature. Tyson explains on the basic atomic structure of protons, neutrons, and electrons, and the nature of nuclear fusion that occurs in most stars. He then discusses the existence of neutrinos that are created by these nuclear processes in stars, and that detecting such sub-atomic particles which normally pass through matter require subterranean facilities like the Super-Kamiokande that were used to detect neutrinos from the supernova SN 1987A in the Large Magellanic Cloud before light from the explosion were observed due to their ability to pass through matter of the dying sun. Tyson compares how neutrinos were postulated by Wolfgang Pauli to account for the conservation of energy from nuclear reactions in the same manner as Darwin's postulate on the long-tongued moth. Tyson concludes by noting that there are neutrinos from the Big Bang still existing in the universe but due to the nature of light, there is a "wall of infinity" that cannot be observed beyond.

Earth 2100

   2009    Nature
Hosted by ABC journalist Bob Woodruff, this two-hour special explores what a worst-case future might look like if humans do not take action on current or impending problems that could threaten civilization. The problems addressed in the program include climate change, overpopulation, and misuse of energy resources. The events parallel the life of a fictitious storyteller, 'Lucy' as she describes how the events affect her life. The program included predictions of a dystopian Earth in the years 2030, 2050, 2085, and 2100 by scientists, historians, social anthropologists, and economists, including Jared Diamond, Thomas Homer-Dixon, Peter Gleick, James Howard Kunstler, Heidi Cullen, and Joseph Tainter. According to Executive Producer Michael Bicks, "this program was developed to show the worst-case scenario for human civilization. Again, we are not saying that these events will happen — rather, that if we fail to seriously address the complex problems of climate change, resource depletion and overpopulation, they are much more likely to happen.

The Secret Science of Sewage

   2021    Technology
Dr George McGavin and Dr Zoe Laughlin set up base camp at one of the UK's biggest sewage works to investigate the revolutionary science finding vital renewable resources and undiscovered life in human waste.
Teaming up with world-class scientists, they search for biological entities in sewage with potentially lifesaving medical properties, find out how pee can generate electricity, how gas from poo can fuel a car and how nutrients in waste can help solve the soil crisis. They follow each stage of the sewage treatment process, revealing what the stuff we flush can tell us about how we live today, and the mind boggling biotechnology being harnessed to clean it, making the wastewater safe enough to return to the environment.

Dynamic Salt

   2016    Technology
Could we get all our energy needs from sea water and the salt it contains? Are we to witness a time when salt will power our engines and factories, and light up our cities? Could this be the final curtain not only for shale gas and oil, but also the burning of fossil fuels and the beginning of a gentler form of energy that is definitely renewable? This documentary explores the latest research on sea water and the way scientists all over the world are working on 'Blue Energy'. This research could bring about a major change in our time.

Inner Worlds Outer Worlds: 1 Akasha

   2012    Culture    HD
There is one vibratory field that connects all things. It has been called Akasha, Logos, the primordial OM, the music of the spheres, the Higgs field, dark energy, and a thousand other names throughout history. The vibratory field is at the root of all true spiritual experience and scientific investigation". It is the same field of energy that saints, Buddhas, yogis, mystics, priests, shamans and seers, have observed by looking within themselves. Many of history's monumental thinkers, such a Pythagoras, Kepler, Leonardo DaVinci, Tesla, and Einstein, have come to the threshold of this great mystery. It is the common link between all religions, all sciences, and the link between our inner worlds and our outer worlds. Inner Worlds was created by Canadian film maker, musician and meditation teacher Daniel Schmidt. The film could be described as the external reflection of his own adventures in meditation. As Daniel came to meditative insights, he realized that these same insights were discovered over and over in spiritual traditions around the world and that all traditions share a common mystical underpinning. He realized that it is this core experience that connects us not only to the mysterious source of all creation, but to eachother as well.

Fracking The New Energy Rush

   2013    Technology
Iain Stewart investigates a new and controversial energy rush for the natural gas found deep underground. Getting it out of the ground involves hydraulic fracturing - or fracking. We travel to America to find to find out what it is, why it is a potential game changer and what we can learn from the US experience". Sometimes, this is right under the places people live in. He meets some of the people who have become rich from fracking as well as the communities worried about the risks. Director Jeff Wilkinson
