Both. The carrot is a positive motivation, and the stick is a negative one.
Control theory
In a game with many players, there can be none, one or many winners and none, one or many losers. A positive sum game is one in which the sum of all the winnings is greater than the sum of all the losses. In theory, then, it should be possible for the winners to compensate the losers but still keep some of the positive sum. But that is in theory!
Yes, although the z-scores associated with p-values of 0.01 and 0.05 have special significance, perhaps mostly for historical reasons, all possible z-scores from negative infinity to positive infinity have meaning in statistical theory and practice.
Prime numbers are positive integers that only have two factors. In theory, there is an infinite amount of them.
You don't need a "law of current" from that, but you can derive it from Ohm's Law.
Conventional Electrical theory (simplified) states that electricity flows from positive to negative in contrast to Electron Theory which supposes negative to positive flow of electrons.
Some people believe magnetic ions have healing properties. The theory is that the body absorbs positive or negative ions to reduce pain, swelling and increase immunity.
The theory belief is that electricity flows from a negative source to a positive source.
Both. The carrot is a positive motivation, and the stick is a negative one.
Because much of the theory of electricity was developed before scientists realised that it was not a moving positive charge that was responsible but a negative one (of the electron).
When we consider electron flow, we think of moving electrons. The electron has a negative charge. This model of current flow, the electron current flow model, follows the movement of those negative charges.As a contrast, we might consider what is called conventional current flow. And that the model of current involves the movement of charges with a positive polarity.
Negative to positive
An atom consists of a sphere of positive charge with negatively charged electron embedded in it,The positive and the negative charges in an atom are equal in magnitude, due to which an atom is electrically neutral. It has no over all negative or positive charge.
The belief that electricity flows out from a negative source seeking a positive conclusion.
A positive theory seeks to understand how something is or how it operates, without making value judgments or prescribing how it should be. It aims to describe and explain phenomena based on empirical evidence and facts, rather than opinions or beliefs.
From anode to cathode.
