photochemistry, known as the law of Grotthus-Draper (by chemists Theodor Grotthuss and John W. Draper ), states that light must be absorbed by a chemical substance that results in a photochemical reaction. The second law of photochemistry, ...
quantum jump can be defined as a change of an electron from one quantum state to another within an atom. It seems to be irregular; the electron "jumps" from one energy level to another very rapidly, after existing for a short time in a stat...
electronic devices hurting our planet Devices that utilize electrical power often emanate electropollution. Electropollution is fundamentally the unseen electromagnetic powers emitted from diverse things which depend on electrical power to ...
the human body, but human brain. The effects of electromagnetism on the human brain are both positive and negative and are nothing short of a cosmic intervention. The affect that electromagnetism has on the human body in turn effects our da...
are contradictory statements on this issue. Many researchers claim that there are not any dangers of cell phones. On the other hand, there are many researchers and health professionals who claim that there are no dangers of cell phones. Thu...
Operational amplifiers are important building blocks for a wide range of electronic circuits. They had their origins in analog computers where they were used in many linear, non-linear and frequency-dependent circuits. Their popularity in c...
negative feedback? and it is the key to having a self-stabilizing system (this is true not only of op-amps? but of any dynamic system in general). This stability gives the op-amp the capacity to work in its linear (active) mode? as opposed ...
