Behavior Definition and 337 Threads

Behavior (American English) or behaviour (British English; see spelling differences) is the actions and mannerisms made by individuals, organisms, systems or artificial entities in conjunction with themselves or their environment, which includes the other systems or organisms around as well as the (inanimate) physical environment. It is the computed response of the system or organism to various stimuli or inputs, whether internal or external, conscious or subconscious, overt or covert, and voluntary or involuntary.Taking a behavior informatics perspective, a behavior consists of actor, operation, interactions, and their properties. This can be represented as a behavior vector.

    Quantum Behavior As Extreme Classical Behavior

    Why can't quantum behavior be explained as an extreme version of classical behavior? For instance, the idea of a small quantum particle being in superposition could be explained by that particle switching between 2 or more states at an extremely high frequency. How high a frequency? Well, on...

    Differential Equations behavior for large t?

    dy/dt = 2 - 2ty y(0) = 1 I am not asked to solve this (I know it's not easy to solve), but what I am asked is, "for large values of t is the solution y(t) greater than, less than, or equal to 1/t"? I would think less than because 1/e^(t^2) converges faster than 1/t, but at the same...

    What is Sound? Exploring Perception, Frequency & Wave Behavior

    I am looking for a definition of sound. Does it have anything to do with what is perceived by the ear, and therefore restricted to certain frequencies? Is it even a perception or is it simply a longitudinal wave? I can find lots of physics material about sound, but I can't find a definition.

    Peculiar Opamp circuit behavior

    An opamp circuit was given in the homework forum: There the circuit was analyzed with the usual assumptions of opamp ideality. But, if the circuit is analyzed with one change to ideality, namely the opamp voltage gain is set to 7 rather than ∞ (this brings with it the change that v+ ≠ v- any...

    Questions about the behavior of the Higgs particle and Higgs field

    1.) If the particle they believe to be the Higgs particle has a mass of 125 GeV, then how is it that the Higgs field itself does not have mass or react with gravity? If it is in fact the field creating the mechanism that gives everything its mass, and its particle form also has mass, why is it...

    Question about ohms law and non-ohmic behavior.
