To better put into perspective the various issues surrounding energy in the 21st century, you need to understand the essential science behind how energy works. And you need a reliable source whose focus is on giving you the facts you need to form your own educated opinions.

Are there other dimensions beyond our own? Is time travel possible? Can we change the past? Are there gateways to parallel universes? All of us have pondered such questions, but there was a time when scientists dismissed these notions as outlandish speculations. Not any more. Today, they are the focus of the most intense scientific activity in recent memory. In Hyperspace, Michio Kaku offers the first book-length tour of the most exciting (and perhaps most bizarre) work in modern physics.

Mercury, a lifeless victim of the Sun’s expanding power. Venus, once thought to be lush and fertile, now known to be trapped within a toxic and boiling atmosphere. Mars, the red planet, doomed by the loss of its atmosphere. Jupiter, twice the size of all the other planets combined, but insubstantial. Saturn, a stunning celestial beauty, the jewel of our Solar System. Uranus, the sideways planet and the first ice giant. Neptune, dark, cold and whipped by supersonic winds. Pluto, the dwarf planet, a frozen rock.

Ken is the Executive Director of the non-profit Science of Light (SOL) a 501(c)3 founded in 2012. Their mission is to raise awareness of mal-illumination; a term coined by John Ott to describe a contemporary health condition that’s akin to malnutrition. He is the past founder and CEO of Ott Light Systems. John Ott inspired Ken’s lifelong passion for light and its effects on human health and behavior. In this episode Ken shares his story, experience working with the famous time-lapse photographer John Ott, and SolShine. Find Ken: SOlshine.orgscienceoflight.orghttps://www.instagram.com/...

Introduzione alla relatività ristretta di Einstein

Andy & Matt discuss one of the most emotive topics associated with UAP. The source of many sci-fi storylines and famous stories, but are alien abductions real? Hosted on Acast. See acast.com/privacy for more information.

In a rarified world of scientific research, a revolution has been brewing. Its activists are not anarchists, but rather Nobel Laureates in physics and economics and pony-tailed graduates, mathematicians, and computer scientists from all over the world. They have formed an iconoclastic think-tank and their radical idea is to create a new science: complexity. They want to know how a primordial soup of simple molecules managed to turn itself into the first living cell--and what the origin of life some four billion years ago can tell us about the process of technological innovation today.

On October 4, 1957, a time of Cold War paranoia, the Soviet Union secretly launched the Earth's first artificial moon. No bigger than a basketball, the tiny satellite was powered by a car battery. Yet, for all its simplicity, Sputnik stunned the world.

Rules of the quantum world seem to say that a cat can be both alive and dead at the same time and a particle can be in two places at once. And that particle is also a wave; everything in the quantum world can described in terms of waves - or entirely in terms of particles. These interpretations were all established by the end of the 1920s, by Erwin Schrödinger, Werner Heisenberg, Paul Dirac, and others. But no one has yet come up with a common sense explanation of what is going on.

Given the fact that there are perhaps 400 billion stars in our galaxy alone and perhaps 400 billion galaxies in the universe, it stands to reason that somewhere out there, in the 14-billion-year-old cosmos, there is or once was a civilization at least as advanced as our own. The sheer enormity of the numbers almost demands that we accept the truth of this hypothesis. Why, then, have we encountered no evidence, no messages, no artifacts of these extraterrestrials?

Sam Harris has discovered that most people, from secular scientists to religious fundamentalists, agree on one point: science has nothing to say on the subject of human values. Indeed, science’s failure to address questions of meaning and morality has become the primary justification for religious faith.The underlying claim is that while science is the best authority on the workings of the physical universe, religion is the best authority on meaning, values, morality, and leading a good life.

Something strange is going on in the cosmos. Scientists are uncovering a catalogue of weird phenomena that simply can’t be explained by our long-established theories of the universe. After decades of fruitless searching, could we finally be catching glimpses of a profound new view of our physical world? Or are we being fooled by cruel tricks of the data? In Space Oddities, Harry Cliff, a physicist who does cutting-edge work on the Large Hadron Collider, provides a riveting look at the universe’s most confounding puzzles.

No subject is bigger than reality itself, and nothing is more challenging to understand, since what counts as reality is undergoing continual revision and has been for centuries. The quest to pin down what's real and what's illusory is both philosophical and scientific, a metaphysical search for ultimate reality that goes back to the ancient Greeks. For the last 400 years, this search has been increasingly guided by scientists, who create theories and test them in order to define and redefine reality.

Best-selling author, superstar physicist, and cofounder of the World Science Festival Brian Greene (The Elegant Universe, The Fabric of the Cosmos) and an ensemble cast led by award-winning actor Paul Rudd (Ant-Man) perform this dramatic story tracing Albert Einstein's discovery of the general theory of relativity.

On September 14, 2015, after 50 years of searching, gravitational waves were detected for the first time, and astronomy changed forever. Up until then, investigation of the universe had depended on electromagnetic radiation: visible light, radio, X-rays, and the rest. But gravitational waves - ripples in the fabric of space and time - are unrelenting, passing through barriers that stop light dead.

Since the beginning of human history Mars has been an alluring dream - the stuff of legends, gods, and mystery. The planet most like ours, it has still been thought impossible to reach, let alone explore and inhabit. Now with the advent of a revolutionary new plan, all this has changed. Leading space exploration authority Robert Zubrin has crafted a daring new blueprint, Mars Direct, presented here with engaging anecdotes. The Case for Mars is not a vision for the far future or one that will cost us impossible billions.

Albert Einstein described Relativity as a "popular explosion" of his famous theory. Written in 1916, it introduced the lay audience to the remarkable perspective which had overturned theoretical physics. Einstein's genius was to express this perspective in understandable terms.

Napoleon's Buttons is the fascinating account of 17 groups of molecules that have greatly influenced the course of history. These molecules provided the impetus for early exploration, and made possible the voyages of discovery that ensued. The molecules resulted in grand feats of engineering and spurred advances in medicine and law; they determined what we now eat, drink, and wear. A change as small as the position of an atom can lead to enormous alterations in the properties of a substance.

Apollo is the behind-the-scenes story of an epic achievement. Based on exhaustive research that included many exclusive interviews, Apollo tells how America went from a standing start to a landing on the moon at a speed that now seems impossible. It describes the unprecedented engineering challenges that had to be overcome to create the mammoth Saturn V and the facilities to launch it. It takes you into the tragedy of the fire on Apollo 1, the first descent to the lunar surface, and the rescue of Apollo 13.
