What is Weird: Definition and 482 Discussions

Psychology is the science of mind and behavior. Psychology includes the study of conscious and unconscious phenomena, as well as feelings and thought. It is an academic discipline of immense scope. Psychologists also seek an understanding of the emergent properties of brains, linking the discipline to neuroscience. As a social science, psychologists aim to understand the behavior of individuals and groups.A professional practitioner or researcher involved in the discipline is called a psychologist. Some psychologists can be classified as a social, behavioral, or cognitive scientists. Some psychologists attempt to understand the role of mental functions in individual and social behavior. Others explore the physiological and biological processes that underlie cognitive functions and behaviors.
Psychologists explore behavior and mental processes, including perception, cognition, attention, emotion, intelligence, subjective experiences, motivation, brain functioning, and personality. Psychologists' interests extend to interpersonal relationships, psychological resilience, family resilience, and other areas within social psychology. Psychologists also consider the unconscious mind. Research psychologists employ empirical methods to infer causal and correlational relationships between psychosocial variables. Some, but not all, clinical and counseling psychologists rely on symbolic interpretation.
While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in several spheres of human activity. By many accounts, psychology ultimately aims to benefit society. Many psychologists are involved in some kind of therapeutic role, practicing in clinical, counseling, or school settings. Other psychologists conduct scientific research on a wide range of topics related to mental processes and behavior. Typically the latter group of psychologists work in academic settings (e.g., universities, medical schools, hospitals). Another group of psychologists is employed in industrial and organizational settings. Yet others are involved in work on human development, aging, sports, health, forensics, and the media.

    What is the Escape Speed Formula and How Do I Use It to Solve Problems?

    problem: Taking the potential energy to be zero at infinite separation, find the potential energy of a 118.0-kg object at the surface of the earth. (Use 6.37E+6 m for the Earth's radius.) I did this and got -7.374E09. It then asks Find the escape speed for a body projected from this...

    Can You Compute Compositions f(g(x)) and g(f(x)) with Given Functions?

    Can you solve such a thing as: f(g(x)) and g(f(x)) Let f(x) = sqr (4-x) D=x < or = to 4 right? and also Let g(x) = sqr(x-3) D = x > or = to 3 Can you solve such a thing.. if so how.. if not why not?

    Isn't this weird? (convergence of a sequence)

    In order to prove, using the \epsilon-N definition, that the sequence \left\{\frac{n^2}{n^2+4}\right\} = \left\{\frac{1}{1+\frac{4}{n^2}}\right\} converges towards 1, I did the following: The sequence converges towards 1 if \forall \epsilon>0, \exists N\in\mathbb{R} \ \mbox{such that}...

    Is 0.9~ equal to 1 in mathematical calculations?

    Okay so most of us know 0.9~ = 1, correct? We find this by doing 1 devided by 3. This makes 0.3~ 0.3~ * 3 = 0.9~ So 0.9~ = 1. As most of us know. But would not 0.3~ = 0.4? Then it would be 0.4 * 3 = 1.2? So 1 / 3 * 3 = 1.2? ¬_` :confused:

    Just a weird idea, friction-less materials

    I just wondered, that our view of how the universe is is ussually WRONG. We've made zero-viscosity fluids, materials with no electrical resistance, and just all together "non-sense" things. Is anyone willing to suggest then that there are materials that do not provide friction(when...

    Weird pattern in exponentiation

    I was looking at the different ways the operations +, *, and exponentiation can work on three numbers x, y, and z. I found a weird pattern when the second operation performed is exponentiation. These are the expressions: (x+y)^z \ x^{(y+z)} \ (x \cdot y)^z \ x^{(y \cdot z)} \ (x^y)^z \...

    Is There a Simpler Way to Handle the Pi in Finding a Derivative?

    I am having a conflict with two different ways of finding a derivative. Here is the function: y=10*sinpi(.01x-2.00t) Yes, that pi is after sin, but not in the paranthesis. This is how the prof gave it to us. This may be my problem, how I am treating the pi. I figure it was factored out...

    Have you ever had a dream about walking corpses stealing your shoes?

    A month or so ago, yet I remember it clearly, I had a funny dream. I was walking in a public place, when I look down and see that my shoes are gone. I say in a loud voice for all to hear, "Alright! Who's the walkin' corpse that took my shoes??" Pretty weird huh? You? jimmy?
