Is There Life After Death

   2011    Science
Everyone from the most simple-minded to the deepest thinking has pondered a question that strikes at the core of our existence: Is there life after death? What happens to the soul after we die? People who have had near-death experiences claim to have visited the other side before getting yanked back into consciousness. Now, some of the brightest minds in science are trying to understand how life can persist beyond the physical and what will it look like. It might be a quantum state based on the fundamental laws of the universe. Ultimately, it is a journey that struggles to decode the most complicated instrument in the universe: the human brain.

The Persistence of Memory

   1980    Science
The idea of intelligence is explored in the concepts of computers (using bits as their basic units of information), whales (in their songs and their disruptions by human activities), DNA, the human brain (the evolution of the brain stem, frontal lobes, neurons, cerebral hemispheres, and corpus callosum under the Triune Brain Model), and man-made structures for collective intelligence (cities, libraries, books, computers, and satellites). The episode ends with speculation on alien intelligence and the information conveyed on the Voyager Golden Record.

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.

What is the Right Diet for You 2of3

   2015    Medicine
It is time to see if personalised dieting will work in normal life. The volunteers have been given one of three diets to follow - based on their genes, their hormones and their psychology. But now they are back at home, trying to stick to their personalised diets with all the stresses and temptations of real life. Dr Chris van Tulleken and Professor Tanya Byron discover how our genetic makeup can make temptation difficult to resist, how understanding the brain reveals what makes us comfort eat and what science can tell us about why we make disastrous food choices.

Is Luck Real

   2014    Science
Do you make your own luck, or does luck make you? Some scientists believe luck is strictly a matter of statistics and probabilities…but others believe unseen forces are at work, and randomness is built into every particle of the universe. We’ll find luck, good and bad, in casinos, basketball courts, genetics labs and the subatomic world. How much does the genetic lottery rule your fate? Are lucky streaks and unfortunate accidents merely our own minds fooling us? It’s a scientific journey that will radically revise your understanding of the laws of nature and the workings of the human brain.
