If the E = hv of quantum theory is one begniling-ly simple later advance in the concept of energy, the supremely famous mass-energy law E = me" is another. This and its import for nuclear energy are usually credited solely to Einstein. The truth is more interesting. 

R. Atkinson and F. Houtermans apply Gamow s theory of potential barrier penetration by quantum tunnelling to suggest how stars can release nuclear energy by synthesis of hydrogen into helium by an (unspecified) cyclic process.

The perturbation A(T f + 2T ) describes the replacement of model densities and inter-nuclear distances by the values that are appropriate for the molecule under scrutiny. Similarly, appropriate reference atomic energies must be used in the atomic-like formula (4.15) to get A °. Ingeniously selected references require small corrections. Nature helps a lot in that matter by keeping the changes of p(r) as small as possible. The bond energy theory is rooted in Eq. (4.47).

Despite many attempts made over more than a century, the exact route to turbulence is still far from clear. This prompted Morkovin (1991) to state One hundred eight years after O. Reynolds demonstrated turbulence in a circular pipe, we still do not understand the nature of the irregular fluctuations at the wall nor the formation of larger coherent eddies convected downstream further from the wall. Neither can we describe the mechanisms of the instabilities that lead to the onset of turbulence in any given pipe nor the Reynolds number (between about 2000 and 100 000) at which it will take place. It is sobering to recall that Reynolds demonstrated this peculiar non-larninar behaviour of fluids before other physicists started on the road to relativity theory, quantum theory, nuclear energy, quarks etc . While some additional researches have clarified some key concepts, the situation about flow transition in a pipe remains the same. 

Three other options are presently being studied, with an eye on including them in the forthcoming 3270 version. One of these is the equations of Helgeson, Kirkham, and Flowers (41). for which further model development is required. The second (42) is based on the hydration theory concept of Stokes and Robinson (43). This also requires further model development. The third set is a model (44) recommended by the European Nuclear Energy Agency for obtaining equilibrium constants for the formation of aqueous complexes of interest in nuclear waste disposal, such as of uranium and plutonium.
