Hello: I wanted to know what does the phrase, "When the going gets weird, the weird turn pro" means. Actually I understood the first part of it. But the second part "the weird turn pro" is not clear to me. What does the word "weird" stand for, here? Any answer is appreciated. Thanks in...

Ok, this isn't a particularly hard integral, but for some reason I don't understand why the answer is what it is. Here's the integral (BTW, it's part of a double integral): \int e^{x/y} dx The answer is: ye^{x/y} dy but I don't understand why. Wouldn't it be in the form e^u, with u being x/y...

Here's something really weird. As can be read in Pressley's "Elementary Differential Geometry": Proposition 1.3: Any reparametrization of a regular curve is regular. And 4 pages later: Exemple 1.8: For the parametrization \gamma(t)=(t,t^2) of the parabola y=x², \dot{\gamma} is never 0 so...

Here I am, asking yet another question. :), Gotta keep you guys busy you know. I am just practicing a bunch of integration questions found in a textbook a friend lent me, and I probably don't need to know how to integrate this, but I am interested anyways :)...

Ok the equation: y=(x-1)^2 How come it has a y intercept of (0,1) but the equation does not have a +1 at the end of it?? I thought all y-intercepts are at the end of the vertex-form equation.

what would be the period of cos(2pi*x)*sin(2pi*x)?? calculator is telling me it's 2, but i somehow don't want to believe that also, what would be the period of cos(2pi*m*x)*sin(2pi*m*x)??

carol's age in years, can be expressed by reversing the digits in her father's age, in years. the sum of the digits in each age is 10. the positive difference between carol's age in years, and her fater's age in years___36 a.> b.< c.= d.uncertain In my opinion, there are four pairs...

If you had a pair of celestial rotating in a circle, both of equal mass size. Would it be possible for the planets to have a shared satellite? Thank you for reading, Alex

We are now studying the one space dimension heat equation u_t = u_{xx} [/tex] The fundamental solution is given as: u(t,x)=\int_{-\infty}^{\infty} \frac{1}{2\sqrt{\pi t}}e^{-(x-y)^2/4t}u_0(y)dy I don't understand where the y comes from. The example in this section is: If u_0(x)=1 , the...

Q1)Electron has both mass and electrical field, can we said that electron itself possesses both mass and electrical energies? What I really mean is when the electron move in high speed, there are increasing of kinetics energy of electrical field and mass energy? In term of relativistic...

Sometimes it seems that my computer generates unwanted internet activity. I know this becuase I can see the activity light on my router blinking. This happens at irregular intervals. And when it happens, my internet connection stops working. I would either have to unplug my internet cable or...

Did anyone else receive a huge Private Message about "M-Cubics"? I didn't start this thread to discuss the "theory", or to discuss the poster, I'm merely interested in whether I have understood what the post is saying. Am I completely dense, or is the entire post simply defining a...

Hey guys; I'm experiencing a really weird problem with my router.. First, my setup: I'm living in the Caribbean so I have to use a goofy ISP. We have a PPPoE DSL connection to them. I then have a Linksys Broadband Firewall Router hooked up to the DSL box, then I have a Linksys Wireless...

The rock is held by two of the same 40 cm strings with ends 70 cm apart and whirled in a circle between them. Neglect gravity. -- i found the radius of the circular motion to be 19.36cm = 0.1936m. now the question is "Now what is the maximum speed the rock can have before the string...

Do you guys get spam that has subjects that just make no sense. I get about 10 of these a day. The subject says stuff like: "caps here, and to make bows th...", "be Kristina tread ", "some sole a proximate". What is the deal with these? I guess that the goal is to get people confused...

Does anyone know what could have caused these kinds of doppler-radar images: http://img452.imageshack.us/img452/909/ind23br.gif More radar images of the same event: http://www.softspotopening.com/

A little block with mass m lies still on the top of a frictionless sphere with radius R. Somebody gently hits the block, causing it to slide down the sphere. The mass loses contact with the sphere when the angle between the positionvector and the vertical equals 0c. The drawing below shows the...

Two loops, A and B, are aligned parallel to each other. There is a current in loop A, which induces a current in loop B. How does the current in loop A change with time? By Lenz's Law, the current in loop B creates a magnetic field which opposes the change in magnetic flux which created it...

Hello! I'm new here, and this is my first post. I hope I have not breached any rules, but here's a rather strange (in my limited intelligence) question I encountered. I shall try to explain the question because I am unable to reproduce the diagram. Two identical narrow slits S1 and S2 are...

Ok, not sure if this is the exact right forum... whatever... So, i have a webcam i use often. and today, its being all weird. Its fine when I'm sitting right in front of it, as usual. but if i lean over out of its view, it starts jumping and gets all freaky and lines across it. same happens...

Seriously, though! Have you ever been flicking through the channels on your television and just been like, "Don't you have ANYTHING good to show me?!" or if you're driving your car, have you ever been like, "C'mon baby, three more miles to the gas station, don't you dare die on - NOOOO! How...

I'm not sure if this question is suppose to be in this section but I'll ask anyway. Does anyone know why we store our excess fat mostly near the stomach and buttocks. I heard it has something to do with forces and physics, and it also seems to be an advantage.

Let f(x) = x if x rational and f(x) = 0 if x is irrational Let g(x) = x^2 if x rational and g(x) = 0 if x is irrational. Both functions are continuous at 0 and discontinuous at each x != 0. How do I show that f is not differentiable at 0? How should I show that g is differentiable...

I'm running Windows 2000 on an older computer. I'm getting these artifacts on images (see attached). It only occurs on JPEGs, nowhere else. It does *not* occur on screen, or even in GIFs. They are randomly appearing - simply refreshing my browser is enough to get a different arrangement. But...

Hi Guys, Last year i remember our instructor while teaching Complex Analysis course gave weird us an weird example! She came up with this because that day most of students bunked that class and she claimed that Bunking class is not an offence,if the person is capable! She told us about an...

Okay this is weird. I have the hairiest legs out of everyone I know my age, yet my chest and back are as bare as a baby's bottom (with the exception of a small patch directly below my belly button - oh and a few around my nipples). I also have the fastest growing, curliest head of hair...

Hi there, I have just set up / taken measurements from an "Einstein de Haas" experiment I set up, but there were a couple of weird effects I cannot explain nor figure out. FWIW, I am competing in the "International Young Physicists' Tournament" in Switzerland this July - should be a great...

Given n, can we find a triplet a, b, c that fits the following conditions: n = a*b+c+5 abs(a-b+c) is minimum but only if n>a+b+abs(c)+5 Where n, a, b are naturals and c is integer. For instance in case of n=65, I have a hunch the best choices are: a = b = 8 c = 1 The...

Hey everyone, I'm having some trouble understanding this, any help would be appreciated: Calculate the density of states for a free particle with momentum \[ \hbar k \] for the angles between \[ \left[ {\theta _0 ,\theta _0 + d\theta } \right] \] relative to an electric field \[...

Don't know what forum to put this in. In what must be the most retarded step I know, we have been told to hand in a report in a "decorative container" worth a mind bogglingly large percentage of the mark. Considering my report is on the anthropic principle and its relation to cosmology...

"The period of function f is 5. If f(1)= 4, f(2)= 5, and f(4)= -2, what is the value of f(7)?" I'm pretty sure this has something to do with function f(x) as a periodic function when a number p>0 exists, such that for all x in the domain of f, f(x + p) = f(x). I don't understand how this...

This seems easy but I'm not getting the right answer! The question: A 0.5 kg ball is thrown into the air. At a height of 20m above the ground, it is traveling at 15 m/s. a)How much work was done by someone at ground level throwing the ball up into the air Ok, for a), Work=Force x...

Weird but real!?? What exactly is 'spontaneous human combustion'?? How and why does it happen? Is it very very rare?

A weird domain and range? anybody up for a challenge y=x^2-2x+1 / x^2-x-2 try it on the gfx calculator and check if this domain and range is right i wrote Domain ( -infinity, -1 ) union (-1,2) union ( 2, infinity) range (-infity, 0) union (-1 to infity) is there an easier way to...

Well here's my question: Do any of you know people who just don't realize that they can't be talked to because they have an EXTREMELY short fuse? When I say extremely short I mean a fuse that leads them to blow up in your face with anger instantaneously. I woudln't mind knowing how you guys...

Anybody else have any habits or rituals that have a logical basis, but appear really screwy to other people? For instance, I always give the second piece of toast a half-turn before buttering. It goes back 45 years. My family could only afford day-old bread at the bakery, and often it was a...

I was looking around at the site http://www.uselectionatlas.org/, and it's weird but true that in many states which John Kerry lost, he got a higher % of the vote than Bill Clinton did when he ran the first time around. For isntance, these are all states Kerry lost Ohio: '92: Clinton 40%...

Right now I'm dipping bread in soy sauce. I put cheese wiz on apples. I put a small amount of barbecue sauce in my mac and cheese. I put salt on bacon (I think this is normal but everybody around me disagrees). I put chocolate milk powder in my cereal. A guy I knew dipped bread in olive...

I want to find two functions f(n,x) and g(n,x) such that f(n,x)sin(g(n,x)) always has a constant arc length over some interval [a,b]. Where n increases the amplitude but decreases the period. Any suggestions?

Why are well educated people almost equally inclined to believe in pseudo-science as everyone else? Or are they? - Smart People Believe in Weird Things, Scientific America I hope this hasn't already been discussed back in 2002! :smile: Ps. A teaser from the article:

While driving to work today, a minivan in front of me had a strange pattern on its rear, the possible cause of which eludes me. Van Tailgate Edit: The sketch is, of course, an approximation. Actual line position and number may vary due to incomplete memory.. We've recently had a lot of...

I obviously lack an understanding of the fundamentals here; maybe someone can help me out. So I'm making a siphon, only instead of using one tube, I'm using a set-up where, due to changes in the tube size, the short end has 3.5 times as much water as the long end. It's not significantly...

This is a VERY silly question that's been bugging me for some time. I've read somewhere that urinals in some bathrooms have a small fly that is purposely painted on. When the urine hits that spot, it is least likely to "splash back". Conveniently, men instinctively aim for that spot when...

Here's another crazy eBay auction, this time they are auctioning snow. SNOW! http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=208&item=3949905269&rd=1&ssPageName=WDVW It's up to $55 with 3 days left! It just snowed this morning, better grab a handful.
