What is Split: Definition and 195 Discussions

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...

http://news.bbc.co.uk/2/hi/uk_news/6057734.stm It's interesting but sounds BS to me. What you think about humans in that many years(~10,000) from now?

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. im working now in a company and they size the air conditioner for the customer according...

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'm not sure if this is the right section to post this thread but here goes... 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 can't grow a decent mustache but I'm a walking hormone. 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! :confused: :grumpy:When u dive into water, as soon as you hit, for a millionith of a second, the surface of the water kind of repels you. It is enough to (from a headdive) break your neck. But after that slight millionth of...

Homework Statement Let H be all the elements of the alternating group A_4 of exponent 2. Show that A_4 is a split extension of H by \mathbb{Z}_3. Homework Equations None. The Attempt at a Solution I have already shown that H is normal in A_4. I also have the proof of the...

I don't think "be yourself" is great advice. Most people aren't quite sure what 'yourself' is.

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...

Good for them! We've been grappling with this problem for years at UCLA . http://www.theonion.com/content/node/52324

OK I apologize I did it again and overlooked a point and thus you sparked an interest, thanks. Metabolic Process 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. :grumpy: Cats have fur for a reason people. Moderator note: This topic has been split from the "if I start dressing up my cat, shoot me" thread since we pretty...

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. Does this sound like anyone to a state standing up to Russian aggression in...

I have posted this elsewhere and it failed to get any response so I am trying it in its own thread. AP wire service. June 15 20XX, Seoul, Korea. In an historic 14 hour operation yesterday, Dr. Kim Sun Hi succeeded in transplanting the right hemisphere of the brain of an unidentified twin into...

Yeah, they'll have those right after they have satellites that can scratch your ass with a laser beam from space. Cheers...

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. Let A, B, C be the following sets : A = {2,4} B = {2,3}...

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 g =...

Hello! I want to know if its possible for me without any sofisticated tools to make the split needed for the interference experiment? I have a laserpoiner that as the the source of light. I have tried to make the split by cutting the back part of a mirror with a smal raizorblade. But it seems...

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...

You know perfectly well what's going on that's making me a little loopy today, Moonbear. :grumpy: Shame on you for picking on me :biggrin:

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 design - like the HTGR [ High Temperature Graphite Reactor ]. For years, the Peach Bottom Unit 1 HTGR...

im not really sure how to do this one because I have forgotten most of the things about trig functions from last year, but here is the problem: (im going to say Ħ=pi because I can't find the character for pi) f(x)= tan((Ħx)/4) when |x|<1 x when |x| =>(greater than or equal to) 1 Im...

I think your erasure of my comments was cavalier, and disrespectful. But, I will post again. I challenge you to actually have dialogue. The planet and the web of life is a large, but closed, system. We have artificially heated this system and stressed many other life forms, including our...

I responded to Ulmo in the sci. Physics strings in regards to the Ekroptic scenario versus the cyclical universe. I know this might be out of context of this thread but I saw it as a opportunity to place the question before you. The idea is...

"The researchers' new discovery involves a gene called MYH16, which had apparently gone unrecognized because of a small mutation that had rendered it inactive for producing some jaw muscles for chewing and biting. The scientists found that this myosin gene was still intact today in other...

“Can the Young's Double Split Experiment, be improved?” "The Uncertainty Principle says that such a better experiment does not exist." Einstein tried in vain, to devise a better measurement. "Many good men have tried" The problem is with the first statement, it implies that...

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? Rock 'n'...
