hey i need help with this as a high school grad ,and one people think happens 2 be a maths prodigy a junior student came once and asked me 2 help him integrate x! i could not give a solution ,now pls can anyone help with this puzzle?

Let K=Q(i,(1+i)^(1/3)). Describe all of K's embeddings in C. (C-Complex Field, Q-Rational Field). Describe? Could it be the answer is just the identity? How could I prove that? Thanks in advance! :smile:

When universe is still a strange point, what is in the universe? (asume big bang did happen and universe was created in a certain time)

I'm reading through a modern physics text (on my own) and it did some very strange manipulation when deriving the relativistic form of the kinetic energy equation. It starts off deriving relativistic force which I understand. Basically, the implicit derivative of (d/dt)(ymv). Y is gamma and is...

Two charges, –16 and +4.0 mC, are fixed in place and separated by 3.0 m. (a) At what spot along a line through the charges is the net electric field zero? Locate this spot relative to the positive charge. (b) What would be the force on a charge of +14 mC placed at this spot? I am totally...

TV, Monitors ? So strange ... Why is all the CRTs and LCDs in 4:3 ratio in their dimensions ? Does it have any scientific reasons ??

Hello, I got this strange email from a guy who must have spammed it out across the globe. I spotted what I thought were a few misconceptions, but I'm not a physicist so I can't give this thing a thorough critique. I'll just paste it below. It's probably one of those cases where some...

Hello, My data gravely perplexes me. I've set up a simple series RC circuit with an AC emf of 14V @ 20Hz. Resistor and capacitor values are 3.9E4 ohms and 4.7E-5 farads respectively. Ideally, the voltage across the resistor should be a simple sine curve, since this is basically an RLC series...

I've always loved talking about physics with people, unfortunately none of my friends are really interested in it at all. Are there any people on here, mainly night owls that go on MSN messenger and would like to talk about physics, chemistry, and those sorts of topics? If so, PM me, it's...

let be (dS/dt)+(gra(S))^2/2m+(LS)+V(x) where L is the Laplacian Operator and V is the potential...could it be considered as the Hamiltan Jacobi equation for a particle under a potential Vtotal=V(x)+(LS) where S is the action

What do the strange values on disc capacitors signify exa 005 and 5D 1KV , why can't they just be abbreviated in a more intuative way like for exa just 10 micro farads ? Also for a small mic how can I tell apart which ends which + or 1 and what do the letters HAI signify on some...

Hi! Can anyone explain to me what this sign means. \equiv

This is a thread to ask why. Here's one on my mind lately considering Arnolds threat to run as President. If conservatives hate liberal Hollywood types, then why do they keep making Presidents out of actors?

You're asked to find lim x-->0 sin7x / 4x The part of this example that I don't understand the most is how they get 1 out of sin7x/7x when x-->0. Sorry about the ridiculously small image. The dimension restrictions are ridiculous, and I didn't notice that the image didn't attach properly...

here we go. originally in root forum, like root under a root under a root etc... just don't know where to start with this one. f(x) = (x+(x+(x+(x+1)^.5)^.5)^.5)^.5)

Hi! I have a big problem with this simple question. I can manage all the other questions on the paper i got except this one, and it's even one of the easier in there. So please gimme suggestions of what formulas to use: A person is struggeling his way up a 8 degree hill with the velocity...

Hey, do you guys sometimes experience a strange feeling--at one moment you realized that something similar, or even identical (such as the same scene, the same dialogue...) has happened before, either in your dreams or happened many many years ago when u are young , but your memory just can't...

Can someone help explain the theory behind the bottom question or give me a hint without giving me the answer. It's a bonus question, but I rather get assistance before copying someone completely. I already know Permutations and Combinations and the Fundamental Counting Principal, I'm just...

Today when I was toying with a water rocket I came upon a strange phenomena. The setup was like this: I had a 625 mL coke bottle, filled half way with water. The cap had a nice hole in it, about 1.5 cm. I turned the bottle upside down, thinking that the water would just gush out, but low and...

Gravity probe B is designed to detect the distortion of space (both the linear compression and lateral shear of the vacuum) that the mass of the Earth produces by it's presence in space and it's rotation on it's axis. The hope is that this might be seen in the anticipated deflection of very...

I was looking at the different ways the operations +, *, and exponentiation can work on three natural 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)} \...

Do we have many stories of weird things happening? I don't neccesarily mean ghostly occurences or strange lights in the sky, rather I am thinking of more mundane but still bizarre perceptions and observations. I would really love to hear your stories. Here are a couple of examples of mine...

There was a woman at our organization who was quite formidable and tyrannical. I work for the group that services everyone's computers and I was loathe to get a call from her. If she had a computer problem she would call in a fury screaming, "I am the director of this department and someone...

For example a folder in my computer has the following name.. {F451F6C3-31EE-1ED1-8EE5-0FC04FC395EE} What can I say about those hex ? Thanks

A Hairless Mexican dog, a coyote with mange, an armadillo without a shell, a hybrid? An interesting story with a [dead] body for evidence. Be sure to watch the video. http://www.woai.com/news/local/story.aspx?content_id=FAE91F84-A264-4AC3-8EA4-9097690CDEFC

I don't know where this will end up, but I am going to start it here. A few nights ago my wife and I where watching TV in the bedroom, we turned off the TV and the light over the bed and went to sleep. After a few minutes (maybe five or ten, I woke up and looked at the TV. It was glowing, but...

Does anyone know of a resolution to the bug and rivet paradox? It is outlined here: http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/bugrivet.html#c1 My first guess is that the rivet does not reach the bug, and the rivet's predictions are wrong because it undergoes infinite acceleration...

Strange idea for exotic matter / antigravity I have spent quite some time on an idea I'd like to present here. Before I start, I'd like to make some points clear (due to some reactions I witnessed on other threads): 1. This theory has not been tested in any way, so I'm not trying to present...

Whatever applies. I like the taste of sweet, strong coffee while I am eating double aged, extra sharp cheddar cheese. Same coffee and a salty turkey sandwich goes great as well. As a Catholic School kid who went to church every morning for some years, I always liked the funerals...

For some reason, something just came to my mind about a strange result I got when doing a photoelectric effect experiment early this spring. I had "monochromatic" LEDs (I am most suspicious about them) shining into a hole in a "box" that contained the photo sensitive "vacuum tube thing" (the...

Do strange stars exist? Apparently they are denser than neutron stars and consist of up down and strange quarks. But are they theory or reality?

There have been strange number systems used in the past in different parts of the world ... do you know any? :biggrin:

Greetings all, I am getting strange results when solving this trig equation. I seem to be able to calculate 4 out 7 of the correct angles but how do i calculate the others? Maybe my method is wrong... A = theta 2sin2A = tanA, considering identities sin2A = 2sinAcosA and tanA =...

1) Find a function, f(x) which is discontinuous at 1, \frac{1}{2}, \frac{1}{3}, \frac{1}{4} ..., but continuous at any other points. Solution (I have come across, probably wrong and a half): f(x) = { 1 for all real x; 0 for 1/x where x is natural numbers. Can anyone tell me the answer to...

A very strange situation? Normally I keep all of this stuff in the S&D Forum but we seem to have an ongoing and genuine mystery in Italy that reportedly has many experts stumped. Since this story has maintained its status as a credible one for some time now I thought that some of you non-S&D...

I've heard about some small chip of some kind that has termendous cooling power when a current is run through it. Apparently it is a high efficiency alternative to a large refrigerator when it is kept in a small, enclosed area. It's equivalent to something like 10 bags of ice or something, I...

Strange radioactivity question. please help fast! I know this is in the k-12 forum too but i wasnt sure if this is college level stuff or not so sorrie if this is in the wrong forum. And I am not telling u to do this for me, i just want to know some equations and anything that wuld help...

Strange radioactivity question. please help fast! well, this is a strange question that i have to do a presentation on. I thought it would be easy but i can't find any information after looking through 2 major physics books and searching online. I even asked a tutor about this and still...

Earlier tonight Tsunami's laptop started producing a very high pitched squealing sound. She thought it might be her hard drive - it did sound a bit like a bearing failure - but to me it sounded more like audio feedback; it wasn't, but it sounded much like that. Then, about an hour ago I had the...

I heard they have developed a watermelon that is red on the outside, yellow rind, and a green center. They say it tastes like any other watermelon. I wish people would leave well-enough alone. I don't want green ketchup, either.
