PPT-Fission

The Psychological Theory For any persons P1 and P2 and times T1 and T2 T1T2 such that P1 exists at T1 and P2 exists at T2 P1 is the same person as P2 only if and because P2 is psychologically continuous with P1.

Chapter. 12.1: Splitting the atom – Nuclear Fission. Inside the Nucleus. Uranium, with 92 protons and 140 neutrons, is one of the largest atoms. Even though its nucleus is so large, around 100 000 000 000 of these nuclei would fit, lined up in 1 mm.. Detailed Study . 3.3. Chapter. . 12.2: Aspects of Fission.

Nuclear power plant. 2. NUCLEAR FUEL. Nuclear . fuel is any material that can be consumed to derive nuclear energy. The most common type of nuclear fuel is fissile elements that can be made to undergo nuclear fission chain reactions in a nuclear reactor . ~bombs and nuclear power. Nuclear fission. ~the separating of a nucleus of an atom.. This is the process used by nuclear power stations (when it is kept under control).. It is also the process of an atom bomb (when it is allowed to run uncontrolled). . Heavy Elements can reduce. energy (i.e. increase binding. energy per nucleon) by. splitting roughly in half..
