Behavior Definition and 337 Threads

Hopefully this isn't a foolish question but, I am up to CalcII and am anxious to apply what I've learned but have found nature fails to provide functions for it's behaviour like textbooks do. Is there a book or something I can read to develop this skill?

So, I've noticed that when I freeze ice cubes these strange icicles appear on the top of the ice. I took a picture, included as an attachment. Not really sure how something like this forms. Please no speculation.

Don't know if this is the right place for such a question... I plotted these graphs based on data taken from the black box of a plane: http://www.planetmobile.it/jumpjack/immagini/volo93-grafici.GIF I can't fully understand these data: looks like while the plane was falling down, it was...

If there were no law requiring the use of seatbelts, would you choose not to wear one? I'm questioning the effectiveness of the seat belt law. I think that someone who is irresponsible enough to not wear a seat belt is also irresponsible enough to ignore the law requiring that they do. While...

I would appreciate some practical advice on a problem I'm having with a project I'm working on. I have implemented a simple voltage adding circuit using an op-amp. (see http://homepages.which.net/~paul.hills/Circuits/Adder/Adder.html for the generic circuit) Using one amp of a LM348...

I noticed when I stick a cylindrical magnet on a smooth metal surface (longways) and roll the magnet along the surface, it does not roll smoothly. Instead, it seems to resist movment, then 'pop' forward into another position. It is almost as if the magnet has a preference on which side sticks...

Hi all, I have attached a notebook which I am doing a calculation in. For some reason, Mathematica is acting inconsistently. When I run the calculation for the first time, it usually doesn't work. By that I mean I get the output that you can see in the notebook attached. You can that...

Homework Statement Use the Mean Value Theorem to show that: a)Suppose f is a diferentiable function on the interval a < b, and suppose f '(x) is not equal to 0 for all x Element Symbol (a,b). Show that f is one-to-one on the interval (a,b). b) Assume that |f ' (x)| < or equal to C < 1...

Here's a problem the TA made but now that I look back at it, I wonder how he did it. A system contains N weakly interacting particles, each of which can be in either one of two states of respective energies \epsilon_1 and \epsilon_2 with \epsilon_1<\epsilon_2. a) With no explicit computation...

My UC Berkeley Master's Thesis in physics education is attached. It has to do with students' conceptions of the limits of prediction in chaotic systems. Feel free to read it and to let me know what you think. Take Care, Jed Stamas Cambridge, MA jed underscore stamas at yahoo dot com

I have been running IV tests on polypyrrole nanowires and i see a time varying resistance that is linear over 3 time periods... can somebody explain this to me?? i am basically a EE student and i need help with the this... maybe it has to do with transport in the wires or some kind of...

Hello All, I'm currently trudging through my physics class which is teaching about electric and magnetic fields, and their interactions. As I have been reading through the textbook, I have been trying to formulate ideas and understand exactly what is happening inside of current carrying...

I was separated from my extended family for many years. When I returned, I noticed similarities among the members' behavior. My mother and first cousin possesses similar beliefs in health, and a general similarity in personality. My second cousin possesses the same sleeping patterns that...

Hi, my first post to this forum: I'm curious whether the hanging mass of the fuselage beneath a helicopter rotor can be said to exhibit pendulum behavior. Specifically, in the case of a helicopter or other rotorcraft with a so-called teetering rotor, no torque is present at the rotor head...

First, I'd like to mention that these are just some random questions I thought up about waves. 1. How can you hear sound through a barrier and why is it muffled when you hear it this way? I know waves are transmitted through materials, so I guess I'm really only asking why the sound is...

Hello everybody! Can anyone tell me about some books on Mechanical/Structural behavior/Properties of Particulate Composite Materials? I would highly appreciate anything that is offered free on the net but If you can tell me about some good books to buy I will surely like that too... posted it on...

is y=sin(x) the end behavior of y=sin(x/2)?

Which of the following describes the behavior of y = cubicroot(x + 2) at x = -2 (A) differentiable (B) corner (C) cusp (D) vertical tangent (E) discontinuity well i graphed the function, and I'm not sure.. i know for sure it isn't E... because f(-2) = 0... it has a value.. uhmm.. as...

Find the vertical asymptotes of the graph of F(x) = (3 - x) / (x^2 - 16) ok if i factor the denominator.. i find the vertical asymptotes to be x = 4, x = -4. The 2nd part of the problem asks: Describe the behavior of f(x) to the left and right of each vertical asymptote.. I'm not sure...

I was trying to find out why when you mix a cup of tea with loose tea in it, the loost tea is first at the bottom of the cup on the outside, but when you take the spoon out, the loost tea moves towards the middle of the bottom of the cup. couldn't find it anywhere else online, thought i'd try...

Perhaps pseudosci. but still interesting. I was wondering if there was a link between a psychological behavior idea of particles and if there was a term for it. Example: Electrons are lazy because they they take the easiest path to the ground Far-fetched example: Particles and atoms...

I turned the light on in my fishtank today and found 2 things: 1. The goldfish had its eyes "plucked" - simply they were missing from the sockets, and the goldfish was swimming upside down gulping for air at first, then tumbling and swimming normally for some time and swimming on belly again...

I am looking for an elegant way of demonstrating the parabolical behavior of the system: \frac{\partial u}{\partial x}+\frac{1}{r}\frac{\partial}{\partial r}(vr)=0 u\frac{\partial u}{\partial x}+v \frac{\partial u}{\partial r}=\frac{1}{r}\frac{\partial}{\partial r}\Big(r...

I would assume there are experimental attempts to use an MMx type interferometer to check out some of the questions that are debated about photons in a G field. For example, if we have a single leg interferometer (no back and forth reflections to gain a greater effective length) and set it up...

Here is a summary of the research published in the June 2005 issue of Psychology, Public Policy and Law, a journal of the American Psychological Association: http://www.eurekalert.org/pub_releases/2005-04/cdri-bai042505.php Also see http://www.news-medical.net/print_article.asp?id=9530...

I have seen a number of discussions and articles regarding the seeming disparity between the behavior of photons through the traditional "two slit" experiment. As I understand this issue, quanta of light will interact in a reinforcing/cancelling wave interference pattern until the apparatus is...

Hi, I have a problem that talk about the behavior of two liquids in contact and a boundary that appears between them. I am lack of theory about this situation do anyone of you could help me to find some paper of articles that talk about this? Thank you, Aron

Howdy- Consider a low pass filter subjected to an AC source (i.e the "output" is the capacitor voltage). I understand mathematically how to assess the frequency reponse of such a circuit. What I am after is a conceptual description of why. Why do capacitors act as shorts to high...

Is it better to forgive others for wrongdoing or is it better to remember and treat them accordingly, or even seek to punish them to correct their faulty behavior as a parent might punish a child? What would happen if everyone agreed that either extreme was the way to go? What is your...

If you had continued to reduce the temperature of your real gas in this experiment (air mixture of mostly nitrogen and oxygen) to lower and lower temperatures, you would observe sudden drops in pressure at 90 K and 77 K. In other words, the behavior of the real gas would deviate significantly...

First of all, my sincere wishes of an Happy Christmas, full of joy, happiness and such feelings that make our life worthfull! I'm studying and researching about Chaos Theory, and currently I'm examining the following iterative equation: Xn+1 = c*(Xn-(Xn^3)/3) I've already managed to...

my understanding of the behavior of hawking radiation (with questions) is as follows: 1) in Q. Mechanics virtual particle/antiparticle pair are created randomly throughout the universe. Q1) without a complete layout of Q.M., why is this? 2) the gravity of a singularity will...

i think i asked a question here a long time ago and nobody fully answered it so here goes: what is the behavior of gravitons. i know they are virtual particles and cannot be observed, but is there a way to manipulate them such as we can with charged particles? also, have we any...

Hello... This may sound like a strange question... nonetheless it is a sincere one... Hence I am curious enough to ask... What is the relationship with the male sexual psyche and their mothers? This is a very general and open ended question.

OK... This is an attempt in trying to make sense out of human behavior... What makes you tick? AND, why?
