What is Symmetry in Physics?  With Tara Shears

Δημοσιεύτηκε στις 14 Ιουν 2017

Symmetry
underlines our whole understanding of the universe. And the deeper we
look, the more symmetries we find, reflecting our world in new and
beautiful ways.

Symmetry
is vital to understanding and predicting how our universe works. The
relationship between symmetry and the mechanics of the universe is
fundamental to physics. From Noether’s theorem to the new and exciting
world of local symmetries being revealed by modern day physics, Tara
Shears explores the physics of symmetry.

By revealing nature’s
parameters, symmetry gives definition to the world as we understand it.
It is a fundamental principle that makes phenomena repeatable and
predictable. But if symmetries are so pervasive and influential in our
world, why do we see so much asymmetry and chaos?

Today’s
computers are lightning-fast. But sometimes we want to make sure that
they can’t solve a particular task quickly (perhaps for security
purposes). This issue lies at the heart of the P vs NP problem, one of
the most famous conundrums in computer science, which Kevin Buzzard will
explore in this Discourse. Can every problem whose solution is quickly
verifiable by a computer, also be quickly solved by a computer?

Are We The First Civilization in the Universe?

Δημοσιεύτηκε στις 1 Αυγ 2017

If
you spent your whole life never meeting another human being, you could
be forgiven for thinking you were the only one to exist. Likewise, since
mankind has never encountered any extraterrestrial forms of life, we
have often come to the conclusion that we are in fact the only living
things in the entire universe.To discern whether we are the first
civilization in the universe we must first explore how the universe and
life came to form in the first place. Our solar system formed when a
fragment of molecular cloud mostly comprised of hydrogen started to
collapse 4.6 billion years ago. Our Sun is known as a second generation
star. The cloud from which our star was formed was created by a first
generation star exploding.Remember Abraham Loeb? He was the guy from
Harvard who thinks that life will be more abundant in ten trillion years
time. Well guess what. He also believes there’s a chance life could
have formed way before our Earth came along.
