I had the great fortune to receive a Nobel Prize in Physics for using electron tunneling to measure the energy gap in superconductors. In this talk I will recollect some of the events that led to this discovery and hopefully I will be able to convey....

The lecture will be devoted to the topic of how the biological world supplies itself with energy to make biology work, and what medical consequences ensue when the energy supply chain in our bodies is damaged or defective. We derive our energy from ....

As a student in the early 1960s, I had the privilege to attend winter seminars organized by my mentor, W. Hoppe, and by M. Perutz, which took place in a small guesthouse in the Bavarian-Austrian Alps. The entire community of a handful of protein cry....

Biological membranes define and compartmentalize the cells of higher organisms. Consisting of membrane proteins and lipids, they are basically impermeable for ions and polar substances, so that electric voltages (_membrane potentialsî) and substanc....

Despite enormous advances in structural studies of biological systems we are frequently left without a clear structure-function correlation and cannot fully describe how different systems actually work. This introduces a major challenge for computer....

Astrophysical objects are able to accelerate atomic nuclei to energies 10^7 times more than man made accelerators such as LHC. _Particles arrive at earth from space with energies as great as 50 joules, a macroscopic energy in a microscopic particle.....

John summarizes the history of the universe, from the Big Bang through the formation of galaxies and the Solar System, and the history of the Earth and some of the special factors enabling the formation of life.  Our future will be hot as the Sun ge....

I shall present and explain the thesis that mankind is on the threshold of a dramatic transition: From an earth, predominantly powered by oil and other fossil fuels, with unsustainable global warming, to a new earth predominantly powered by "clean" s....

The fact that our modern world is so completely and precariously balanced on Science, Engineering and Technology (SET) makes an understanding of these disciplines by all in positions of significant responsibility vital. lthough wise decision-making ....

Chemistry is not merely a science of making observations in order to better understand Nature. Our science is creative and productive, generating substances of very high value from almost nothing. Chemists already have made enormous contribution to....

It is generally accepted that the global warming, which we undoubtedly observe, is the result of an increased concentration of greenhouse gases like carbon dioxide and methane in the atmosphere.  Within this scenario it is evident that we have to re....
