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.

The Clean Room

The Clean Room

   2014    Science
This episode is centered around how science, in particular the work of Clair Patterson (voiced in animated sequences by Richard Gere[33]) in the middle of the 20th century, has been able to determine the age of the Earth. Tyson first describes how the Earth was formed from the coalescence of matter some millions of years after the formation of the Sun, and while scientists can examine the formations in rock stratum to date some geological events, these can only trace back millions of years. Instead, scientists have used the debris from meteor impacts, such as the Meteor Crater in Arizona, knowing that the material from such meteors coming from the asteroid belt would have been made at the same time as the Earth. Patterson also examined the levels of lead in the common environment and in deeper parts of the oceans and Antarctic ice, showing that lead had only been brought to the surface in recent times. He would discover that the higher levels of lead were from the use of tetraethyllead in leaded gasoline resulting in government-mandated restrictions on the use of lead.

Sisters of the Sun

Sisters of the Sun

   2014    Science
The constellation of the Pleiades provides a vehicle for us to explore a series of paradoxes and epochal discoveries for humanity. The untold story of the modern "sisters of the sun," the early 20th century female astronomers, led by two deaf women, at Harvard who catalogued the stars. It's also the story of the young British woman who joined forces with them, her defiance of the world's leading expert, and how she taught the world what the stars are really made of.

- These are top-quality videos carefully chosen by our team to ensure a high level of interest in the subject matter and excellent quality of the documentaries themselves.

- Help us build a useful Internet filled with high-quality, enjoyable, and informative content. Join us in our project by becoming a subscriber or making a donation!

- If you want to collaborate with us, send us a link to a video you think would be of interest through our social media channels. We will then review it, index it, produce and add the subtitles, and make it easily accessible from our website.

- If you wish to collaborate even further with our community, you can produce the subtitles yourself. Subtitles tutorial. When they’re ready, send the subtitle files to our social media along with the video link so we can proceed as mentioned above.

- We are working hard on this project to offer you all this content. Your donations and subscriptions enable us to continue providing this valuable service.

- We are firmly committed to the promotion of Culture, Learning, and Collaborative Altruism.

- Our warmest greetings and thanks for your interest and support!

Documentary Films

A documentary film or documentary is a non-fictional motion-picture intended to "document reality, primarily for the purposes of instruction, education or maintaining a historical record".

Early documentary films, originally called "actuality films", lasted one minute or less. Over time, documentaries have evolved to become longer in length, and to include more categories. Some examples are educational, observational and docufiction. Documentaries are very informative, and are often used within schools as a resource to teach various principles. Documentary filmmakers have a responsibility to be truthful to their vision of the world without intentionally misrepresenting a topic.

Documentary practice is the complex process of creating documentary projects. It refers to what people do with media devices, content, form, and production strategies to address the creative, ethical, and conceptual problems and choices that arise as they make documentaries. Documentary filmmaking can be used as a form of journalism, advocacy, or personal expression.

Box office analysts have noted that this film genre has become increasingly successful in theatrical release with films such as Fahrenheit 9/11, Super Size Me, Food, Inc., Earth, March of the Penguins, and An Inconvenient Truth among the most prominent examples. Documentaries are shown in schools around the world in order to educate students. Used to introduce various topics to children, they are often used with a school lesson or shown many times to reinforce an idea.

Media platforms have provided an avenue for the growth of the documentary-film genre. These platforms have increased the distribution area and ease-of-accessibility.
