Limitations of the Scientific Method

 · Many experiments support the notion that light behaves like a longitudinal wave. Taken collectively, these experiments have given rise to the wave theory of light. Other experiments, however, support the notion that light behaves as a particle. Instead of throwing out one theory and keeping the other, physicists maintain a wave/particle duality to describe the …

Principles and Procedures of Sieving Analysis

For a lot of experiments there is a tendency to use an excessively large sample to get more accurate test results. However, for sieving analysis, the accuracy of the result will be reduced if the sample is too large, because this will not permit each of the particles an opportunity to present themselves on the test sieve surface. Generally, a 25–100g sample is recommended. A …


Glueball. In particle physics, a glueball (also gluonium, gluon-ball) is a hypothetical composite particle. It consists solely of gluon particles, without valence quarks. Such a state is possible because gluons carry color charge and experience the strong interaction between themselves. Glueballs are extremely difficult to identify in particle
