The most mysterious star in the universe | Tabetha Boyajian

Something massive, with roughly 1,000 times the area of Earth, is blocking the light coming from a distant star known as KIC 8462852, and nobody is quite sure what it is. As astronomer Tabetha Boyajian investigated this perplexing celestial object, a colleague suggested something unusual: Could it be an alien-built megastructure? Such an extraordinary idea would require extraordinary evidence. In this talk, Boyajian gives us a look at how scientists search for and test hypotheses when faced with the unknown.

 

Quantum mechanics at the macroscopic scale – Mark Kasevich (SETI Talks 2016)

Quantum mechanics is a foundation of physics, chemistry and materials science. Still, there is an ongoing debate about the emergence of the classical, macroscopic world from the well-understood microscopic world of quantum mechanics. We contribute to this discourse by demonstrating quantum superposition of massive particles at the distance (0.5 m) and time scales (2 s) of everyday life, thereby advancing the state-of-the-art of atom de Broglie wave interferometry by nearly two orders of magnitude [1]. In addition to testing a central tenet of quantum mechanics, we pave the way for new precision tests of gravity, including the possible observation of gravitational waves and tests of the equivalence principle. In related experimental work, we demonstrate that entangled clusters of approximately 1000 atoms can be used to achieve 10-fold improvement in the sensitivity of quantum sensors based on atomic transitions; the levels of performance achieved could not have been realized with any competing (non-entangled) method.

essica Herrin: “Find Your Extraordinary” | Talks at Google

Jessica Herrin, CEO & Founder of Stella & Dot, joins Talks at Google for a Q&A as she discusses her book “Find Your Extraordinary: Dream Bigger, Live Happier, and Achieve Success on Your Own Terms”.

 

ABOUT THE BOOK

What if you could, with a little effort, live an extraordinary life? A life in which you felt deep passion for everything you did, and always had time for what matters most? A life in which you had the power, the daring, and the will to make your boldest dreams come true, all while you happily left feelings of inadequacy or guilt behind?

In FIND YOUR EXTRAORDINARY: DREAM BIGGER, LIVE HAPPIER, AND ACHIEVE SUCCESS ON YOUR OWN TERMS Jessica DiLullo Herrin, serial entrepreneur and founder and CEO of Stella & Dot Family Brands, shows how the classic traits of a successful entrepreneur are ones each of us can develop to live an extraordinary life, whether we work a corporate job, run a family, or run our own business. Offering realistic and attainable steps to achieve success on our own terms, Herrin inspires and empowers us to dial up the sound of our own voices and make our authentic dreams a reality.
