Nuclear Reactions

Mr. Anderson discusses nuclear reactions, explaining their significance and the fundamental forces involved. He compares chemical and nuclear reactions, highlighting the role of valence electrons and nucleons. The video covers energy differences, focusing on Einstein's E=mc^2, and details fission and fusion processes. The potential of fusion energy for sustainable power is also explored.
