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.

Journey to Space

   2015    Technology    3D    HD
NASA’s next era will be its greatest yet. That is the clear 'roadmap' painted by Journey To Space. The film absolutely annihilates the perception that the space program died with the end of the Space Shuttle Program by showcasing the exciting plans NASA and the space community are working on, and the challenges they must overcome to carry out audacious missions such as landing astronauts on Mars and capturing asteroids. In the past half century, humans have punched through the stratosphere, walked on the moon, and lived continuously in orbit. In the coming decades, our unquenchable curiosity will take our species beyond the cradle of Earth to touch the face of another world. Strap in for the next giant leap. Next stop ... Mars!

Zappa

   2020    Art
An in-depth look into the life and work of the iconic artist and musician Frank Zappa. As a singer, songwriter, rock guitarist, classical composter, recording producer and even occasional film director, Frank Zappa was as difficult to describe as his eclectic music was throughout his 30-year career.
Zappa was without peer, a singular entity who branched out in countless directions, and in the process, became one of the most important and influential musical artists of the latter-20th century. With his most famous band, The Mothers of Invention, he blended rock, jazz, classical, doo-wop, R&B and avant-garde stylings with strange, sexually-tinged lyrics and absurd stage theatrics to create a wholly unique live experience, while in the studio producing outside-the-mainstream albums.

Mysteries of Sleep

   2020    Medicine
Why do we sleep? And what does sleep have to do with memory, trauma, and our emotions? From fruit flies to whales, virtually every animal sleeps. But why? Why do we need to spend nearly a third of our lives in such a defenseless state? Scientists are peering more deeply into the sleeping brain than ever before, discovering just how powerful sleep can be, playing a role in everything from memory retention and emotional regulation to removing waste from our brains. So why are we getting so little of it?
