Athena Lecture 2016: Order, Disorder, Complex Fluids & Life Professor Al...

Δημοσιεύτηκε στις 29 Ιουν 2016

The
Athena Lecture series celebrates the achievements of women in science,
technology and medicine. It is given annually by a prominent female
scientist who has made outstanding contributions in any of these fields.

Professor
Alice Gast research interests are in surface and interfacial phenomena,
in particular the physics of complex fluids, colloidal suspensions,
micelles, membranes and proteins. Her areas of research include
ordering, magnetic suspensions, protein lipid interactions, and enzymes
at surfaces. She has applied light, x-ray and neutron scattering along
with statistical mechanical methods to study colloidal, polymeric and
biological systems.

She was a faculty member in Chemical
Engineering at Stanford University from 1985 to 2001, being promoted to
full professor in 1995. At Stanford she was also a Courtesy Professor of
Chemistry and affiliated with the Stanford Synchrotron Radiation
Laboratory. In 2001, she moved to the Massachusetts Institute of
Technology where she served as Vice-President for Research and Associate
Provost and held the Robert T. Haslam Chair in Chemical Engineering
until 2006.

She is the co-author of “Physical Chemistry of
Surfaces, 7th edition” with Arthur Adamson and has over 125
peer-reviewed publications, and over 200 conference presentations.

Since
2006 she has worked full-time as an academic leader and administrator.
Prior to her appointment as President of Imperial College London in
September 2014, Professor Gast was the 13th President of Lehigh
University, Pennsylvania.

She is a fellow of the American Academy
of Arts and Sciences and a member of the National Academy of
Engineering. She is also a member and has held various leadership roles
in the American Association for the Advancement of Science, the American
Chemical Society, the American Institute of Chemical Engineers, and the
American Physical Society.

Professor Gast is a member of a number of international advisory committees and boards.

Professor
Gast earned her bachelor's degree in Chemical Engineering from
University of Southern California in 1980 and her master's and Ph.D. in
Chemical Engineering from Princeton University in 1981 and 1984. She
spent several years of her scientific career overseas, first as a
postdoctoral student on a North Atlantic Treaty Organization (NATO)
fellowship at the École Supérieure de Physique et de Chimie
Industrielles in Paris. While serving as professor of chemical
engineering at Stanford University, she returned to Paris for a
sabbatical as a John Simon Guggenheim Memorial Foundation Fellow in
1991. In 1999, she was an Alexander von Humboldt Foundation Fellow in
Munich, Germany.

Professor Gast is married to Bradley J. Askins, and they have two children, Rebecca and David.

Mathematics, Measurement and Money - Professor Norman Biggs

                     



Mathematics, Measurement and Money - Professor Norman Biggs

An overview of Mathematics, Measurement and Money and their evolution over time http://www.gresham.ac.uk/lectures-and...

THE JOINT LONDON MATHEMATICAL SOCIETY/ GRESHAM COLLEGE ANNUAL LECTURE

Throughout
its brief history, mathematics has been closely linked with measurement
and money. In the ancient settlements the rules of arithmetic and
geometry were used to solve problems about the allocation of food and
resources. When life became more complex, the use of coined money led to
computational problems that required good algorithms for their
solution.

Nowadays we rely on mathematics for security, and the
links between information and money have become blurred. Can mathematics
keep us safe?

The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectures-and...

Gresham
College has been giving free public lectures since 1597. This tradition
continues today with all of our five or so public lectures a week being
made available for free download from our website. There are currently
over 1,900 lectures free to access or download from the website.

Ripples In Space: Gravitational Waves in Our Future

                   





Ripples In Space: Gravitational Waves in Our Future

Ζωντανή μετάδοση στις 17 Ιουν 2016

After
decades of effort, the era of gravitational wave astronomy is finally
here. Ground-based instruments like LIGO have opened up humanity's ears
to the ripples of spacetime.

But the LIGO results represent just
one slice of the gravitational wave spectrum. There is a lower-frequency
rumble in spacetime that requires a space-based instrument to hear.

This
Hangout will feature a discussion of LISA Pathfinder, a mission led by
the European Space Agency with contributions from several European
Member States and NASA, which seeks to demonstrate the technologies
needed to build a space-based gravitational wave observatory.

Paul
McNamara of ESA and Ira Thorpe of NASA will explain the exciting first
results from LISA Pathfinder, which were published and announced on June
7th.

The Science of Juno ‘s Mission to Jupiter

                   





The Science of Juno ‘s Mission to Jupiter

Δημοσιεύτηκε στις 30 Ιουν 2016

During
a news briefing from NASA’s Jet Propulsion Laboratory in Pasadena,
California the science team involved with the Juno mission to Jupiter
talked about the scientific goals of the mission. This Fourth of July,
the solar-powered Juno spacecraft will arrive at our solar system’s most
massive planet after an almost five-year journey. Once in Jupiter’s
orbit, the spacecraft will circle the Jovian world 37 times during 20
months, skimming to within 3,100 miles (5,000 kilometers) above the
cloud tops. This is the first time a spacecraft will orbit the poles of
Jupiter, providing new answers to ongoing mysteries about the planet’s
core, composition and magnetic fields.

The Mind After Midnight: Where Do You Go When You Go to Sleep?

  



The Mind After Midnight: Where Do You Go When You Go to Sleep?

Δημοσιεύτηκε στις 18 Μαρ 2015

We
spend a third of our lives asleep. Every organism on Earth—from rats to
dolphins to fruit flies to microorganisms—relies on sleep for its
survival, yet science is still wrestling with a fundamental question:
Why does sleep exist? During Shakespeare and Cervantes' time, sleep was
likened to death, with body and mind falling into a deep stillness
before resurrecting each new day. In reality, sleep is a flurry of
action. Trillions of neurons light up. The endocrine system kicks into
overdrive. The bloodstream is flooded with a potent cocktail of
critically vital hormones. Such vibrant activity begs the question:
Where do we go when we go to sleep? Based on new sleep research, there
are tantalizing signposts. We delved into the one-eyed, half-brained
sleep of some animals; eavesdropped on dreams to understand their
cognitive significance; and investigated extreme and bizarre sleeping
behaviors like “sleep sex” and “sleep violence.”
