Future Accelerators for Astro-Particle Physics
One of the most remarkable results of astro-particle Physics has been the success of the Standard Model, recently culminated in the discovery of the Higgs particle (Ho). However, the Ho is observable only in few channels at the LHC, in the presence o....

The simple Balmer spectrum of atomic hydrogen has provided the Rosetta stone for deciphering the strange laws of quantum physics during the early 20th century. Four decades ago, Doppler-free laser spectroscopy opened a new chapter in the exploratio....

Maxwell's electromagnetic theory (now 150 years old) seemed in its comprehensive way to be capable of answering all of the questions one might ever pose about the theory of light. But that spell was broken in 1900 by Planck's discovery that light bea....

The discovery of superconductivity in hole doped La2CuO4 was motivated by the interest to find this phenomenon in an oxide. After the discovery near 35 K, copper oxides with transition temperatures of up to 131 K at normal pressure were found, i.e.....

Neutrinos have been the origin of an impressive number of ‘surprises’. We know that neutrinos have tiny masses and that oscillations are occurring spontaneously between neutrino species. But additional new discoveries may be ahead of us and t....

Throughout the 20th century it was widely accepted that a light microscope relying on conventional optical lenses cannot discern details that are much finer than about half the wavelength of light (200-400 nm), due to diffraction. However, in the 199....

Some seeds of what to do in the climate/energy controversy are contained in what will be. In this talk I shall ask everyone to jump over contemporary politics and make a mental journey to a time, several centuries from now, when nobody uses carbon-....

Two of the great scientific and technical revolutions of the 20th century were the discovery of the quantum nature of the submicroscopic world, and the advent of information science and engineering. Both of these have had a profound effect not only o....

Our brains are always generating electrical signals, even if we close our eyes, plug our ears, and lie in a warm bath. These signals are called cortical noise because they don't correlate with any sensation or thought of which we are aware. I will ....

The spectrum of a frequency comb, commonly generated by a mode-locked femtosecond laser, consists of several hundred thousand precisely evenly spaced spectral lines. Such laser frequency combs have revolutionized the art of measuring the frequency of....

In 1879 Crookes discovered that air seemed to ionize spontaneously. With the discovery in 1896 of radioactivity by Henri Becquerel it appeared that the mystery was solved. However a number of physicists sought a quantitative agreement between the....
