NOTHING: The Science of Emptiness | 2014
NOTHING: The Science of Emptiness | 2014 Ambakisye-Okang Dukuzumurenyi 13 Views • 5 years ago

Why is there something rather than nothing? And what does ‘nothing’ really mean? More than a philosophical musing, understanding nothing may be the key to unlocking deep mysteries of the universe, from dark energy to why particles have mass. Journalist John Hockenberry hosts Nobel laureate Frank Wilczek, esteemed cosmologist John Barrow, and leading physicists Paul Davies and George Ellis as they explore physics, philosophy and the nothing they share.

The Illusion of Certainty: Risk, Probability, and Chance | 2015
The Illusion of Certainty: Risk, Probability, and Chance | 2015 Ambakisye-Okang Dukuzumurenyi 13 Views • 5 years ago

Stuff happens. The weather forecast says it’s sunny, but you just got drenched. You got a flu shot—but you’re sick in bed with the flu. Your best friend from Boston met your other best friend from San Francisco. Coincidentally. What are the odds? Risk, probability, chance, coincidence—they play a significant role in the way we make decisions about health, education, relationships, and money. But where does this data come from and what does it really mean? How does the brain find patterns and where can these patterns take us? When should we ditch the data and go with our gut? Join us in a captivating discussion that will demystify the chancy side of life.

Marcia Bartusiak joins Kip Thorne, Laura Danly and Rainer Weiss to demonstrate how two observatories on opposite sides of the country, called LIGO (Laser Interferometer Gravitational-wave Observatory), may open a new window on observing the cosmos—one based not in light but in gravity. Scientists have embarked on this joint experiment, seeking whispers of far-away violence—like the collision between distant black holes—rippling through the cosmos. It’s taken nearly a century, but technology has finally caught up to Einstein’s brilliance. His 1916 General Theory of Relativity predicted the existence of gravitational waves—undulations in the very fabric of space and time—and LIGO researchers are now poised to detect them.

Spark of Genius? Awakening a Better Brain | 2015 Ambakisye-Okang Dukuzumurenyi 13 Views • 5 years ago

How far would you go to improve your focus, memory, or even learning ability? Would you be willing to strap on headgear that delivers electrical shocks to targeted areas of your brain? You may soon have that option. It’s called trans-cranial direct current stimulation, and it’s currently being tested on soldiers and used by gamers, students, and others looking for a cognitive edge. But questions linger: does it work? What are potential long-term effects? And how should it be regulated?
