    1. One argument against continuing research on the atom is that the cost continues to increase at an alarming rate, and the benefits seem to be declining. Whereas quantum chemistry experiments as early as 80 years ago were very cheap and yielded considerable practical results, now very few if any practical results are emerging, but the costs of experiments continues to increase. On the other hand a common argument for the continued research in atomic and subatomic structure is the desire for a greater understanding of the universe. As we study the interactions of very small particles, we can gain a better understanding of how they work together to ultimately create the world we live in. Also there is a practical goal of understanding subatomic particles. Current data on how atoms and electrons interact is based on observation alone, and the reasons are unknown. For this reason, the predictions are occasionally vastly inaccurate when involved in larger systems. For example, we cannot predict the energy states of an electron accurately once the number of electrons goes above 1, if insight can be shed into the design of the particles that because the behavior we observe, it will be the most significant practical discovery since the discovery of chemistry itself.…
