Soviet Physics Uspekhi, 1977
Global problems are problems which must be solved on a global scale. Already in ancient times such problems were described in artistic and religious books; they were, for example, The Last Judgement, The Universal Flood.

Energy forms and their extensive scale are remarkably significant for the ways that societies are organized. This article shows the importance of how societies are ‘energized’ and especially the global growth of ‘fossil fuel societies’. Much social thought remains oblivious to the energy revolution realized over the past two to three centuries which ...

On the organic energy gap problem
Journal of Physics: Condensed Matter, 2013In conjugated organic molecules, the difference between the HOMO and LUMO Kohn-Sham eigenvalues is significantly smaller than the transport gap measured experimentally. We discuss here, within a local-orbital formulation of DFT, how this problem can be corrected using appropriate hybrid potentials, that add a fraction of Hartree-Fock exchange ...

Energy problems in life evolution
Biochemistry (Moscow), 2005Evolutionary aspects of bioenergetics are considered. These include the origin of the first organisms, UV-protection and the beginnings of anoxygenic photosynthesis, the electron donor problem of life and the appearance of oxygenic photosynthesis, oxygen danger and strategies of defense, and the role of oxygen in programmed cell death.

Energy Problems in Latin America
Science, 1984Present energy consumption patterns, known reserves of conventional energy sources (oil, gas, coal, and hydroelectricity), and the impact of the oil crisis on the oil-importing countries of Latin America are discussed. New approaches to energy use, including improvements on end-use efficiency, fuel substitutions, nonconventional energy sources, and ...

Computers Analyze Energy Problems
Computer, 1978The energy crisis of the 1970's, perhaps fortunately, is occurring at a time when the computational power of the computer is far enough advanced to contribute significantly to the solution of the resulting problems. Four technical sessions at NCC last month sampled some of these contributions and forecast some of the requirements energy problems will ...

A Soluble Problem in Energy Bands
Physical Review, 1952The problem of an electron moving in a periodic simple cubic potential of the form $cosx+cosy+cosz$ is investigated, with particular attention to the nature of the wave functions, Wannier functions, degeneracy of overlapping bands, etc. It is well known that this problem is separable, leading to Mathieu's equation for the functions of $x$, $y$, and $z$.

REFLECTIONS ON THE ENERGY PROBLEM AS A WHOLE
Energy, 1981Abstract The energy crisis has been and is still being regarded as an aggregate of discrete economic and technological problems confronting the economic and political leadership of individual nations. The forecasting of the evolution of these problems is generally confined to the time frame of two decades or so, typically to the end of the century ...
