\frac{dv_{x}}{dt} = 2\omega (v_{y}\sin{\varphi} - v_{z}\cos{\varphi}) \frac{dv_{y}}{dt} = 2\omega (-v_{x}\sin{\varphi}) \frac{dv_{z}}{dt} = 2\omega (v_{x}\cos{\varphi}) Ok, so I suppose this will give me a velocity vector dependent on time t ... is this correct? Also, when I...

Homework Statement An object is dropped from rest at height H = 40m above the ground at latitude 31.3^{o}S. Calculate the final displacement, in magnitude and direction, due to the Coriolis effect. Homework Equations \Omega = \omega \left( \begin{array}{cc} 0\\ \cos{\varphi}\\...

Homework Statement 1. Establish the vector identity \nabla . (B x A) = (\nabla x A).B - A.(\nabla x B) 2. Calculate the partial derivative with respect to x_{k} of the quadratic form A_{rs}x_{r}x_{s} with the A_{rs} all constant, i.e. calculate A_{rs}x_{r}x_{s,k} Homework Equations The...

Ok with that in mind, does MWI imply that if you are killed in, for example, a car accident, would your consciousness be "shifted" to an alternate reality where you survive? Or would it only apply to situations where there are only 2 possible outcomes (because if you die in a car accident, there...

So it just seems that the results of your experiment always have the same outcome...I suppose you would start to question that after a while, why you keep surviving when there is an equal chance of dying.

Hey guys, I'm having a bit of trouble getting my head around the quantum suicide and immortality thought experiment, http://en.wikipedia.org/wiki/Quantum_suicide_and_immortality" (Sorry to quote Wikipedia, lol) IF the Many Worlds interpretation of QM is true, would this imply that the...

Thanks for clarifying that, I think I was referring to all strangers, not a particular individual. But maybe a person isn't considered "particular" until you actually acknowledge them. For example, the probably of seeing "a person" in the street is very high, but if you find out his name and...

Ok, maybe I was exaggerating in that instance :-p I should probably study quantum mechanics a bit harder though, I have an exam next week. But I'm trying to say that if the probability of something happening is extremely low, it doesn't mean that it has to happen, sometime, somewhere. Can...

It wasn't me who made this association but my aunt. She knew the woman well and instantly associated the situation with her, thinking that it was something that she would do (my cousin took in a breath to blow out the candles, and then they disappeared just as he was about to blow them out...

The probability of running into someone you know is much higher than running into somebody you haven't seen for 30 years and on the other side of the country, I think it's the latter that's more significant in that situation. This is a pretty trivial point, but the number of people you don't...

I keep hearing the same old arguments, about Nucleus accumbens, recalling information, eyewitness testimonies etc. It seems to me that this is a way of denying everything that I've said, or attempts to render everything that I've said useless or irrelevant. If you disagree with this statement...

Good point, but in my opinion this seems much, much stranger than a shuddering fan or toilet. I once was trying to get some sleep when I heard the aforementioned shuddering/groaning sound, it really freaked me out to the point where I got out of bed to investigate, and it was just the pedestal...

Georgina, I think you posted a bit late, turns out the candles were re-lit and tested, over and over again (I wasn't in the room, but other told me when I decided to spark up this discussion again earlier on with my family). ^_^ Oh and the thread was initially called "Do ghosts exist?", but...

Finally, a plausible explanation! ^_^ But seriously, how often do 20 people breathe out simultaneously and in the exact direction of the cake? For this to be correct, everyone would need to exhale with identical amounts of force, or be standing in positions that compensate for the velocity of...

I decided to start up a discussion with my family about that night, and my mother and aunt did indeed relight the candles after everybody had retreated - I myself wasn't there when they did, so I'm only citing what they told me. They tried blowing out the candles from different angles, walking...
