I just won my grant application (just for a mini-internal grant offered through our university's "Innovative Technology Center", just enough to give myself and my undergraduate student travel funds) to support our study of our implementation of team-based learning. Yeah! :biggrin: :biggrin...
Carlo Rovelli and Lee Smolin have recently taken diametrically opposed positions on whether time is a basic part of reality or merely an emergent feature----like for example temperature, or the surface of a liquid.
The surface of a liquid is well-defined at our macro scale, but if you look...
Hi,
I am stuck on this question as I haven't encountered anything similar to it. Normally I have only dealt with pipe with one inlet/outlet.
Homework Statement
I am given a diagram of the pipe shown on the attachment (Sorry for the crude diagram).
Hosted it while the attachment is "reviewed"...
Good afternoon PF,
I have been a lurker of this forum for over a year and it is now my time to seek academic advice. I am a university student who has recently finished first year. I have taken honors calculus, physics, chemistry, biology, and sociology and obtained very good standing in...
I'm having difficulty understanding the geometry of a spacetime split as it applies to geometric algebra. I understand vectors, bivectors, and trivectors and I understand geometric products and wedge products. My impression is that a spacetime split let's you decompose an electromagnetic field...
What would it mean to "transfer data directly from brain to brain"? We can assume that "data" in the brain amounts to some spatial-temporal pattern of activation across many neurons. This is a very reasonable assumption to make in light of what we know about neuroscience.
There's no way to...
Nature may have handed scientists a new clue in a longstanding mystery: how matter beat out antimatter for dominance of the universe. Early data from twin experiments at the Tevatron, the world's reigning particle accelerator at Fermi National Accelerator Laboratory (Fermilab) in Batavia, Ill...
hello everybody,
in fact,im asking for a help in a matter confused me alot,its about how can i select the right (split,mini split,portable,window,etc) air conditioner,which is not central air conditioner.

Couldn't think of a better place to post this. I'm writing a document in latex that has several very large equations in it. I can split them up so that they take up two or three lines using the \begin{split} command or \begin{align} command, but If I need to split a line that is contained within...

I am solving the NLSE (nonlinear schroedinger equation) using the Fourier Split Step Method in MATLAB. To avoid MATLAB's boundary reflection problems and phase discontinuity's you naturally have to make the...
Hi all.
I am studying the use of split step Fourier method to solve NLS-typed equations.
One problem is that, for this type of equations:
iAt+Axx+|A|^2A+C=0, where C is a constant
How shall I implement the split step Fourier method?
I find no where to put my constant C because it is not...

I know that after giving birth a woman can go into postpartum depression. This will change how she looks because she will not have the vitality going on. More of a frown and a propensity to blow up at small incidents. Like spilt milk...
Vector proof that diagonals of rhomb split in ratio 1/2.
[SIZE="2"][SIZE="4"]Homework Statement
Hi. For my math homework I have to prove with vectors(we are currently learning that) that diagonals of any rhomb split in half in ratio 1/2.
Homework Equations
A,B,C,D are end points of...
I've always wondered why the physics community was split the way it is. Why do we have people who are theorists and others who are experimentalists. It seems to me that every scientist should ideally be a mix of both. I've noticed that other science fields don't really have this split(at...
This has always fasinated me, I am only like a kid so don't hate me!

whoa for the biggest 1st post bump ever
I've been involved in a few discussions over racism this week, so it's all new and fresh to me; well, I decided to post my thoughts here, for historical reference.
This thread was looking for "scientifical" definition of human races that could be used in...
1. Two slits are 0.153 mm apart. A mixture of red light (wavelength = 665 nm) and yellow-green light (wavelength = 565 nm) falls on the slits. A flat observation screen is located 2.17 m away. What is the distance on the screen between the third-order red fringe and the third-order yellow-green...
1. In a Young's double-slit experiment, the seventh dark fringe is located 0.029 m to the side of the central bright finge on a flat screen, which is 1.1 m away from the slits. The separation between the slits is 1.5 x 10^-4 m. What is the wavelength of the light being used?
2. wavelength...
Hi! This is my first post on these forums.
I'm having some problems with the split operator + FFT algorithm to solve the Schrödinger equation in time. A real Gauss curve in a zero potential environment should simply flatten out, but I get two peaks as the following Matlab run shows...
OK I apologize I did it again and overlooked a point and thus you sparked an interest, thanks.

In oxidations of glucose, as described in respiration, energy is released and is shown to be held within atp’s as reserved energy but we also know this reaction is what gives...
Dressing your cats is stupid. Its like putting a collar on them. I'd like to put a collar around your neck that rings all day long. Cats have fur for a reason people.

Apparently I didn't make clear what bothers me. I'm happy to set aside the silliness of there being two Bobs, one in each branch that occurs after Bob makes a measurement. And I concede that your idea of choosing, at random, by the Born rule, one of those branches for Bob's consciousness-token...
A laser in visible is used in Raman spectroscopy and the resultant spectrum is in IR and Microwave region(which means molecular vibrations and rotations are excited), what type of interaction is this that induces these levels? ( I cannot think more than..."To be Raman active molecules should...
Following the Ukranian vs. Russian oil stand off last week, 250 of the Ukrainian's 450 deputies have put their names to a vote of non confidance in the government, who have agreed to double their payment to Russia.

Being logically inept (never took a class, and don't know what Rose and AKG are talking about), I've always imagined there was direct correlation to set theory, so please excuse my ignorance.
Someone tell me where this is wrong.

Im trying to turn this equation into 2 separate equations in order to place it in a runge kutta problem. This is the proposed problem and conditions:
\frac{d^2f}{dx^2} + f = 0
allowing
f (x) = A\cos x + B\sin x
f ' (x) = -A\sin x + B\cos x
f '' (x) = -A\cos x - B\sin x
and

Hello!

Here is the question I had trouble with it:
How to prove that an isolated photon cannot split into two photons going in direction other than the original direction.
I thought photon doesn't have mass, then
energy = momentum.
from momentum conservation law. If photon split into two...
Hi. I have 1 computer, and obvoisly, a TV. What I want to do is play Grand Theft Auto vice City multiplayer, either using a split screen, or having one go to the TV, and the other one on the computer. Because GTA:VC does not come with this, the only way is if I open 2 Grand Theft Auto Vice...
Jim,
The above statements are untrue.
True, Chernobyl was a graphite moderated design - but that in and of itself
was not the design defect. One CAN make a safe graphite moderated

“Can the Young's Double Split Experiment, be improved?”

Hello.
Here is a circuit layout based on the ideas of Edwin Gray and Stefan Hartmann.
We all know that when a difference of potential is set along a circuit, the charges goes from one terminal to the other, and finally deplete the source.
Now, I explain briefly how the proposed circuit...
A good 95% of the great rock acts of the '60's and '70's are now either slumming it by touring with just old material, fallen off the charts with recent failures or have yet to resurface. Did their style grow stale, their fans become disillusioned, or did they tire of each other?
