I find this stuff to be amazing.
Overview: Eleven dimensions, parallel universes, and a world made out of strings. It’s not science fiction, it’s string theory.
Beginning with a brief consideration of classical physics, which concentrates on the major conflicts in physics, Greene establishes a historical context for string theory as a necessary means of integrating the probabilistic world of the standard model of particle physics and the deterministic Newtonian physics of the macroscopic world. Greene discusses the essential problem facing modern physics: unification of Albert Einstein’s theory of General Relativity and Quantum Mechanics. Greene suggests that string theory is the solution to these two conflicting approaches. Greene frequently uses analogies and thought experiments to provide a means for the layman to come to terms with the theory which has the potential to create a unified theory of physics.

Summer snowstorms. Disastrous flooding. Devastating wind and ice storms. Rampaging wildfires. Ruinous drought. Our weather has taken a turn for the extreme. And it’s going to get worse. As intense and unpredictable weather becomes the new normal, how can we adapt and survive? #DocZone

It’s not your imagination. The weather has changed, is changing, and will continue to change. More torrential rain, more intense heat, more ice storms, more drought. It’s the new normal, and we all need to immediately start adapting if we want to protect our homes and families from the destructive effects of the wild weather that is now a part of our lives.
WEATHER GONE WILD explores recent extreme weather events and the scientific projections of what we can expect over the next few decades: wild weather is going to become more common, and even wilder and more destructive. What we can we do to protect ourselves, our families, and the towns and cities where we live?
By the year 2050, just 35 years from now, Canada can expect:
• Double the number of extremely heavy precipitation events – with periods of drought in between.
• 5 times as many hot days over 30 degrees.
• 100% increase in wildfires.
• 50% less snowfall across the prairies.
• More hail and 50% more ice storms.
• More intense hurricanes.
As a result, the new global buzzword is “adaptation”, as cities and citizens scramble to protect themselves. What can we do to give ourselves the best chance of dodging this coming bullet? WEATHER GONE WILD travels to Calgary, Toronto, New York, Miami and Rotterdam to detail the dangers of the destructive new weather patterns, and show the innovative plans in each city to protect people and property from the weather’s devastating effects.
In Canada, everything from farming, to the insurance industry, to building codes will have to change if we’re going to weather the coming storms. Most Canadian cities are particularly vulnerable because their aging sewer, drain, and electrical systems need to be massively upgraded to ensure a safe future.
As Blair Feltmate, University of Waterloo professor and Chair of Canada’s Climate Change Adaptation Project says, “It’s mission-critical for the country. We have to weather-harden the system. Climate change will continue to happen. We need to figure out, what are we going to do about it?”
WEATHER GONE WILD answers that question with some practical steps Canadians can take to prepare themselves for destructive weather. Even conservative estimates show that for every dollar spent now on weather adaptation, six will be saved when damaging storms do strike.

Origin of Humans – National Geographic Documentary 2016
Human evolution is the evolutionary process that led to the emergence of anatomically modern humans. The topic typically focuses on the evolutionary history of the primates—in particular the genus Homo, and the emergence of Homo sapiens as a distinct species of the hominids (or “great apes”)—rather than studying the earlier history that led to the primates. The study of human evolution involves many scientific disciplines, including physical anthropology, primatology, archaeology, paleontology, neurobiology, ethology, linguistics, evolutionary psychology, embryology and genetics. Genetic studies show that primates diverged from other mammals about 85 million years ago, in the Late Cretaceous period, and the earliest fossils appear in the Paleocene, around 55 million years ago. Within the Hominoidea (apes) superfamily, the Hominidae family diverged from the Hylobatidae (gibbon) family some 15–20 million years ago; African great apes (subfamily Homininae) diverged from orangutans (Ponginae) about 14 million years ago; the Hominini tribe (humans, Australopithecines and other extinct biped genera, and chimpanzees) parted from the Gorillini tribe (gorillas) about 8 million years ago; and, in turn, the subtribes Hominina (humans and biped ancestors) and Panina (chimps) separated about 7.5 million years ago to 5.6 million years ago.
