Science moves on two legs: experiments and theory. Sometimes theory comes first, but most of the times it is the reverse. In this realm of Condensed Matter Nuclear Science, the well-known theories of nuclear reactions do not explain the experimental observations. One option is to say that experiments are faulty. This is the easiest way to comment. We know that experiments performed by tens of different experimentalists with many different techniques have shown anomalies. They have proven the existence of excess heat, production of helium-4, helium-3, tritium, neutrons, transmutations, and strange radiation. This first option cannot be accepted. The second option remains. We have entered a new field of science, and a lot needs to be done before a valid theory can be developed. We need many more experimental facts, so that a full picture of Low Energy Nuclear Science can be understood, and also developed for the benefit of mankind.Volume 25 is another contribution to our understanding of Condensed Matter Nuclear Science.
