To concentrate energy in this fashion would violate something called "the second law of thermodynamics". TO CONCENTRATE ENERGY IN THIS FASHION WOULD VIOLATE SOMETHING CALLED THE SECOND LAW OF THERMO DYNAMICS
 such enormous blocks of time as to be insignificant on a per second basis. Secondly, chemical reactions are easily controlled by changing quantities, concentrations, temperatures, pressures, states of mixtures, and so on, and this makes them easy to take note of and to study. The rate of radioactive changes, however, could not apparently be altered. The early investigators quickly found that the breakdown of uranium-238, for instance, could not be hastened by heat, pressure, changes in chemical combination, or, indeed, anything else they could think of. It remained incredibly slow. But despite all this, radioactivity had at last been discovered and the intensity of its energies was recognized and pointed out in 1902 by Marie Curie and her husband Pierre Curie (1859-1906). Where, then, did the energy come from? Could it come from the outside? Could the radioactive atoms somehow collect energy from their surroundings, concentrate it several million-fold, and then let it out all at once?
