Recently, I have become fascinated with the many ways in which racism is being used in our society today. No, not the actual instances of racism, but rather how the word or accusation of racism is thrown around by our politicians. Also, it seems as if it is mostly used by the liberals. Originally, racism was used by politicians to mean that same thing as its literal definition: hating someone because of their race. But that has all changed; at least 95 percent of the time racism is now used to mean something else.
Electric fish produce their electrical fields from a specialized structure called an electric organ. This is made up of modified muscle or nerve cells, which became specialized for producing bioelectric fields stronger than those that normal nerves or muscles produce. Typically this organ is located in the tail of the electric fish. The electrical output of the organ is called the electric organ discharge (EOD).
Electric potential is actually defined as the NEGATIVE potential function of electric field (not the vector calculus potential function, but its negative), as is any concept of potential in physics, in order that we can think of it as a form of energy. This means that electric field is the negative gradient of electric potential. If you've never heard of the term gradient, all it means is a vector of derivatives of a scalar function of space, each component of which is a derivative of this function relative to the respective direction in the coordinate system.
