well, don't know if anyone reads the books... but one way to find out... who reads them eh? well, my girls at camp are doing "wizarding for muggles" which is a harry potter themed two weeks at camp. its been loads of fun. the other day the 6th book came out and we went to Borders in Keene to...

hello,i have question to ask here. :smile: 1. which of the following is not correct for an ideal gas? A. the average kinetic energy of the gas increases with temperature B. the force of repulsion between molecules is proportional to the distance between them C. the gas...

g'day everyone... i was wondering the significance of Mr Gann's square of nine, and how he could just find this "magical" thing and then apply it to the markets... Also, what is the mathematics behind it? I've looked it up on google but it doesn't have anything about either of these...

Hi, I know this is a physics/math forum, but I'd really like some help on this equilibrium question. :frown: Consider this reaction: 2NO2 <---> N2O2 If I increase the pressure, then the system will shift to the right, and thus the forward reaction rate will increase. After awhile, a...

Hello I've been learning the basics of physics over the past few weeks and thought I knew what they meant when they would refer to the dimensions of something for instance if you asked me what are the dimensions of acceleration I'd say 'change in velocity/time'' or 'v2-v1/T' but I came across a...

why does the red dot on Jupiter i think its like a storm or something or a hurricane but does anybody know why it does not stop? and the cause of it ? thak u craig

I have been playing around with an idea for a few years and I am interested in receiving any feedback. I am an amateur, so if there are any issues with my logic, please feel free to straighten out my thoughts. First, imagine 2 astronauts floating in space. The first astronaut has an atomic...

this is probably in the wrong forum but... I've seen how paypal and other sources encrypt HTML. but how exactly does it work? how does a browser read the encrypted text and know what to display. I must admit that google has failed me on this one :frown:

try this, there are eight bags. each bag contains 10 balls. one of those bags contains balls weighing 2 kg(all balls weigh the same). All the other balls weigh 1 kg. you have a weighing machine (not a balance). in one weighing u have to find out which bag contains the faulty balls.

The stars in the sky are all emitting their own light. The light is reflected for infinitely many times and part of the light energy will be stored in objects. But why is the sky so dark? Why is it not bright?

- The game proceeds by rounds. At the start of each round, X is some mystery individual. A round begins by the latest winner (or me for the first round) attributing one property to X. Ex: X is dead. or X is in my car. or X is a dead president of the USA. - A property must apply to more...

Monkey see, mokey do. 1st poster: X is green. 2nd poster: X is native to Florida. 3rd poster: X is a reptile. 4th poster: X is not a mammal. This breaks a rule: You must actually narrow the options. 5th poster: X's jaws can exert thousands pounds of pressure per square inch when closing...

I’m puzzled by these two oxides of nitrogen, especially with NO, how do they exist, what favors them? If nitrogen has 1s2 2s2 2 px1 py1 pz1 configuration how or why does he form compound with only one oxygen atom ? Nitrogen has +1 oxidation number here right? So by what kind of connection...

everybody seems to know at least one of the "proofs" that 1=2 or 1=-1, etc but i had never seen this one before. check it out: everybody knows that log(1+x) = x-\frac{x^2}{2} + \frac{x^3}{3} - ... plug in x=1 & the series converges & we get log2 = 1 - 1/2 + 1/3 - 1/4 + 1/5 - 1/6 + 1/7 -...

On a street market I bought an old signed portret of a girl, it is really nice and everyone likes it. One day I was looking on the internet and found another portret by the painter, this time a boy: http://x2.putfile.com/6/15805291684.jpg Then I saw the same seller also had the same...

I'm graphing equations, and I ran into a snag. I assumed that the graph would be the same for both of the following: y=x^2 and y=-x^2 since any negative number squared is equal to it's absolute value squared. However, the book showed equation 2 as having an inverted graph of equation...

http://www.activemind.com/Mysterious/Topics/OakIsland/ This has been absolutely fascinating to me ever since I heard about it. It really astounds me to see the legnths that someone has gone to in order to protect whatever lies at the bottom of this pit. The engineering is quite astounding...

I want to know more about dark matter. Please tell me: Why do scientists think that there should be dark matter?

I want to know why we can easily slide on ice when we wear skating shoes. Originally, I guess it is due to the friction between the metal and the ice. But I think it is not the correct answer. Could anyone help me with this problem. Thanks a lot, Sarah :smile:

I have a few questions that had been bothering me the past few days. First off, why am I born with this particular consciousness and why am i born this "way" as oppose to an infinite other possibilities? Is it because this is how the chemicals in my brain happened to arranged itself out of all...

how can a seires of electical imoulses in the brain generate consiusness

This crystal was left over after the water in a tabletop foundation evaporated. The fountain is a collection of rocks glued together that the water tumbles over. The crystals are off-white, slightly straw-colured. The image is about 2X actual size. Any idea what the mineral may be?

Hi, I'm looking to solutions of: 2^n+Q=m^2 , where Q=1 . Obviously, n must be odd. I already know the trivial solution: 2^3+1=3^2 and I've started using a naive PARI/gp program for finding (n,m) up to n=59 . No success yet. Do you know about other solutions or about some theory ? This is...

Hey, I thought of a good brain teaser. I have another account on this forum. Try to find out what my other username is, there are hints in my profile that are NOT true, just clues. I expect some people to get it, so please, put the answer in white.

Quantum Mystery #1 - Complimentarity Principle Hi all - Making sense of the standard double-pinhole experiment is not easy for the layman! In order for me to better understand complimentarity, an experiment is proposed. What is wrong with this thought experiment? Please view (you may need to...

ok... So, we see the sun everyday, right? So let's say you are standing on one point of the Earth looking at the sun rise... At where must you point a laser cannon in order to hit the sun dead centre? and why? :confused:

Evening everyone, This is a rather odd question: why do we yawn? Is there any biological reason for it? Why do we yawn when we see other people yawn or think about it? Oh, just typing this post is making me yawn! :zzz:

find the cross product a x b of the vectors a = 5.0m,i and b=4.3m,k 5.0m\ast 4.3m\ast \sin (90)=22m^2,\hat {j} The back of the book gives -(22m^2)\hat {j} Where does the minus sign come from?

Magic Square Hello, Don't know, which forum, so i put it to general... Yesterday i saw something like an magician on an exposition, showing some math to angle for attention. He asked the audience to give him a number between 41 and 100. So he got the 47. He worked out a magic...

Belongs in a 'nature' forum, but this is as close as it gets. Why do some birds (pigeons, starlings) bob their heads (front and back) when they walk? I have two hypotheses: 1] They have lower retinal retentiveness, and must hold an image on their eye longer to resolve it. They move their...

Sorry if this is the most elementary question ever, but hey, I gots ta know man! Is the number 2.3 even or odd? :confused: The Rev

From Wikipidia John Wheeler derived the concept of the quantum foam in 1955. It is also referred to as spacetime foam and bears a superficial resemblance to the old concept of the ether (or Aether). How does the time component of this" foam" progress? is it governed by the expansion rate of...

Has anyone actually seen it done? I'm sitting here staring at my petty collection of 1248 songs on my 40GB and the little bar at the bottom of the screen is telling me it's less than 1/8th full. HOW THE **** AM I SUPPOSED TO FILL UP 40GB THESE GUYS ARE INSANE!

have a look a the diagram heavy particle of mass m is tied to one end of a string which is of length l. The other end is attached to the ceiling. The particle forms uniform circular motion. Angular velocity of omega. String is angle theta. Ignore friction and mass of string. Find magnitude...

How do lasers make use of the quantum theory of the atom. I tried to look it up but I couldn't understand what they were saying. :confused:

you've all seen one before, a lamp that turns on when you touch a metal part of it. i was wondering how they worked...? Here are my ideas on how it works: well it can't be sending an electric current through you, that would just be dangerous and wouldn't relly serve any purpose. then i...

I just wonder what's the name of the serries 1/1!+2/2!+3/3!... I know it equals e but I just whant to know how it's called. PS. Titels of good books abot serries would allso be welcome.

Is there an incompleteness which, over all others, defines our existence?

Why is HCl called hydrochloric acid, not just "chloric" acid? I mean, we don't say hydronitric acid, nor do we say hydrosulfuric acid. But then why is HCl called hydrochloric acid, not just chloric acid? (i mean, we do add the hydrogen for acid) My guess is that this is so because the...

ok, here it goes, why is e^(pi.i)=-1 ?
