Using examples from his own work Foldscope: one-dollar origami microscope, Paperfuge: a twenty-cent high-speed centrifuge , Dr. He combines his passion for basic science with development of affordable and accessible technologies that can be used for science education, research, and public health in resource poor settings with the goal of democratizing access to scientific tools.
He is best known for developing the ultra-low-cost paper microscope Foldscope and Paperfuge, a cent hand-powered centrifuge made of paper and string. Manu Prakash received a B. The recent announcements of the first ever detections of gravitational waves from colliding black holes and neutron stars have launched a new era of gravitational wave astrophysics. Gravitational waves were predicted by Einstein a hundred years earlier.
I will describe the science, technology, and human story behind these discoveries that provide a completely new window into some of the most violent and warped events in the Universe. Nergis Mavalvala is a physicist whose research focuses on the detection of gravitational waves from violent events in the cosmos that warp and ripple the very fabric of spacetime. She was a member of the scientific team that announced the first direct detection of gravitational waves from colliding black holes using the Laser Interferometer Gravitational-wave Observatory LIGO detectors in February She received a B.
She was a postdoctoral fellow and research scientist at the California Institute of Technology between and In her spare time, she loves to bicycle long distances, play sports, and hang out with her family. By going 2 km underground and creating an ultra-clean laboratory it is possible to address some very fundamental questions about our Universe: How does the Sun burn? With the Sudbury Neutrino Observatory SNO we were able to observe new properties of neutrinos that go beyond the Standard Model of Elementary Particles and confirm that the models of how the Sun burns are very accurate.
With the expanded laboratory SNOLAB we are welcoming the world in collaborative experiments that are looking for the properties of Dark Matter particles, seeking further properties of neutrinos and looking for neutrino signals from supernovae in our galaxy, from the Earth and from the Sun.

The advantages created by the development of one of the lowest radioactivity laboratories in the world and the resulting fundamental science will be described. Arthur McDonald is a native of Sydney, N. He is a member of the Board of Directors of the Perimeter Institute. Although they are thousands of light years away, neutron stars can act as very precise cosmic beacons — a celestial gift that sheds light on some of the most interesting problems in modern science.
We will explore these strange objects, explain how astronomers are using them to study issues ranging from the origins of the Universe to the very nature of matter, and even listen to the cosmic symphony they create. Kaspi uses techniques of radio and X-ray astronomy to study rapidly rotating, highly magnetized neutron stars. She has done significant work involving radio pulsars and magnetars. More specifically, she has contributed among other things to the study of binary pulsar dynamics, the neutron star population, as well as the study of magnetars, the most highly magnetized objects known in the Universe.
She is the R. In particular, I will concentrate on the concept of causality, and why causality implies that nothing can travel faster than the speed of light in vacuum. Miguel Alcubierre was born in Mexico City in In this area he has concentrated on the study of sources of gravitational waves, and particularly black hole collisions.
He is author of more than 50 publications, as well as a textbook published by Oxford University Press. Where do we come from? What are we? Where are we going?
Albert Einstein Memorial Lectures
The discovery of the Higgs Boson at the LHC provides new insights into these basic questions about the Universe, marking the start of a new era in fundamental physics, and opening new vistas in astrophysics and cosmology as well as particle physics. His research interests focus on the phenomenological aspects of elementary particle physics and its connections with astrophysics, cosmology and quantum gravity. Much of his work relates directly to interpreting results of searches for new particles. He was one of the first to study how the Higgs boson could be produced and discovered.
He is currently very active in efforts to understand the Higgs particle discovered recently at CERN, as well as its implications for possible new physics such as dark matter and supersymmetry. He also studies possible future particle accelerators, such as the Compact Linear Collider CLIC and future circular colliders, is known for his relentless efforts to promote global collaboration in particle physics.
We know since Einstein seminal paper of on the photoelectric effect that light, known since Maxwell to be an electromagnetic wave, is also made of discrete quanta, the photons. This strange wave-particle dualism has opened the way to the quantum theory and revolutionized physics. At the same time, they believed that these ideal experiments would be forever impossible to turn into actual ones in the laboratory.
A major difficulty to realize these experiments with photons is that they are very fragile and elusive particles, usually destroyed upon detection. Technological advances have recently changed this state of affairs and made it possible to manipulate photons in ways which were previously thought impossible. By studying this strange behaviour, we get a deeper knowledge about the quantum laws and we learn tricks that we hope to use one day for developing new technologies which could improve the precision of measurements, the secrecy of communications or the power of computer simulations.
He is the recipient, with David Wineland, of the Nobel Prize in physics. In this presentation for the general public, Dr. Zeilinger will explain some of the fundamental issues in quantum mechanics and show how their application opens up new avenues to a completely novel future information technology.
And the concept of entanglement implies that two or more systems can be separated over large distances and still form one unity. All these concepts lead to exciting and novel applications like quantum computation, quantum communication, quantum cryptography and quantum teleportation. In the talk, Zeilinger will sketch some of the most recent results in this extremely active world-wide research program and present his personal reasons why he believes that someday in the future, we will have absolutely secure communication and ultrafast computation based on these quantum phenomena.
This development confirms once more that the most interesting possibilities for novel applications arise from deep fundamental investigations. His pioneering conceptual and experimental contributions to the foundations of quantum physics have become the cornerstone of the rapidly evolving field of quantum information. His future research goals include quantum communication and quantum teleportation using satellites and ultrafast optical quantum computers.
The stages of his career include M. Among his prizes are the Inaugural Newton Medal of the U.

The LHC will provide a deeper understanding of the universe and the insights gained could change our view of the world. Heuer will explain some of the reasons for the excitement surrounding the LHC. The LHC is expected to yield insights into the origin of mass, the nature of dark matter and the existence of hidden extra dimensions. The talk will address the exciting physics prospects offered by the LHC, and present first results taken by the LHC since the start of data taking in March last year.
Heuer is widely recognized for his leadership in the development of experimental techniques, and the construction and running of large subatomic particle detector systems. In the early s I thought and worked hard at trying to find a way to obtain an oscillator for frequencies higher than those available from known electronics, in order to do very high resolution spectroscopy. Finally, I suddenly had the idea to put enough excess atoms or molecules in an upper state, and provide stimulated emission.
My student Jim Gordon and I made this work first in the microwave range, primarily as a test. The resulting maser for microwave amplification by simulated emission of radiation generated an exciting field and many people jumped into it to make microwave oscillators and amplifiers. But after a few years I pushed myself to move on to much shorter wavelengths.
Arthur Schawlow and I then wrote a paper on how such stimulated emission oscillators could be produced at wavelengths as short as those of light — we called it an optical maser, but it soon was renamed the laser light amplification by stimulated emission of radiation. After publication of our theoretical discussion, many scientists were excited and the first working system was made by Theodore Maiman at the Hughes Labs, a pulsed ruby laser. The first continuously oscillation system was made by one of my former students, Ali Javan, with Wm.
Industry by then recognized the importance of this field, and all the first lasers were built in industrial labs. Lasers are now a wonderful field for science and for a wide variety of technical applications — all an outgrowth of spectroscopy, a field Herzberg helped develop importantly. I presently use lasers to do infrared interferometry on stars with three separate telescopes. Lasers have helped astronomy in many ways, in particular producing a rapid growth of interferometry for measurement of stellar sizes and shapes.
Our interferometer is the only one, however, which uses heterodyne detection, provided by laser local oscillators, which hence allows interferometry in very narrow bandwidths which can avoid spectral lines due to surrounding gas.

This allows measurement of old and active stars quite directly, without interference from their emitted gases. I will report some of the measurements, showing the changes in size of some stars, the dust shells they have blown off and expansion of these shells, along with other details not seen until such techniques became possible.
