Scientific American Partnership
Congrats! Hey there, It's been ages since I was posting regularly on PF but I'm still subscribed and keep track of what's going on. I remember when the forum started and Greg was just a kid. I think from memory he was 16 or 17. It's great to see how things have gone and that it has gained...- Raavin

Graduate Is it possible that light doesn't 'propagate' in a vacuum?
jdavel said "I don't understand what this means. Does your satement, "...'apparent distance' is the result of interaction." mean the same thing as, interaction causes 'apparent distance'?" Well...yes. Further on I've tried to explain it a bit more clearly. Not sure how... -
Graduate Is it possible that light doesn't 'propagate' in a vacuum?
This is where the other stuff I am thinking about sort of fit's in. My thought is that all 'matter' in the universe exists in a infinitesimal/zero dimensional point as something analogous but not the same as light, in that it can exist in the same physical space, and that 'apparent distance' is... -
Graduate Is it possible that light doesn't 'propagate' in a vacuum?
I'm certainly not refuting anything. It all works out the way it works out. The calculations all seem to work out (to the extent that they are fairly accurate with a bit of uncertainty thrown in). No major problem there. The emission of a photon and the absorption at a 'distance' doesn't happen... -
Graduate Is it possible that light doesn't 'propagate' in a vacuum?
Just in case you couldn't tell, in the words of a famous philosopher "I have no professional training". I'm just playing around with ideas. Mmmm, unfortunately I put the cart before the horse and forgot to mention that the other part of the hypothesis is that the apparent distance between... -
Help with reverse siphon break?
Mmmm, yes, that might just work. For some reason I was getting stuck on the larger container 'siphoning' the fluid out rather than taking the feed tube out of the bottom of the container. Now that I think about it, you can get pet water feeders that you attach an inverted bottle to and it feeds...- Raavin

Graduate Is it possible that light doesn't 'propagate' in a vacuum?
I have been thinking again about a Hypothesis that I have been getting together for a while now. I say hypothesis because I don't have enough ability to develop it into something one could call a theory in the mathematical sense of the term. I know people hate that but life doesn't always go to... -
Help with reverse siphon break?
Help with reverse siphon break? Hey there, Not sure if this is possible but... I was wondering if there was a way to set something up so that one liquid would siphon into a lower container and stop when the liquid reached the level of the tube opening without using any sort of valve...- Raavin

Ending Apple's Cult of Mac Addicts
People talk about the Microsoft monopoly all the time but no-one seems to see that apple is far worse. Apple even include code in their 'hardware' so that you can't run their OS, even if you pay for it, on another platform, unless you already own one and then yu technically can't use them both...- Raavin

High School Physics Equation Map: Solve Problems Easily
Physics equation map? Does anyone know if there is some sort of 'map' or flowchart available whereby you can use the information you have and trace your way through directions to get another result eg. start at distance/time ==Differentiate=> velocity =differentiate=>...- Raavin

Graduate Could Virtual Wavefunctions Revolutionize Quantum Mechanics?
I'm an idiot but in lay terms are you talking about all wavefunctions (particles and their properties) being linked regardless of apparent distance and these wavefunctions interacting in a phase space where, if we are to use an analogue to 3d space, everything is colocated?? Raavin [?]- Raavin

Undergrad How Can You Calculate the Length of a Sine Wave's Curve?
Ok, so we scale so that 2.5 or even 2.25 waves fit, it would seem logical that we get the same ratio of area scaling because we have the extra full half wave or part wave with a symmetrical division. The problem arises when we don't have a full half because for example the area of the 1st 1/4 of...- Raavin

Undergrad How Can You Calculate the Length of a Sine Wave's Curve?
Ok, the scale thing makes perfect sense. I don't think I'm going to get the result I was looking for but another question. Unfortunately as I said, my maths is poor. Just going on intuition however, if you scale by half,including the length, the area under the curve reduces to a quarter right...- Raavin

What do you think about the Mac G5
That's really interesting. They also used a single processor in the Dual Dell the G5 and used OSX up against Redhat when it would seem that they could have used SUSE linux on each machine for a more direct comparison of hardware specific power. Although they did use less memory in the G5 which...- Raavin

Undergrad How Can You Calculate the Length of a Sine Wave's Curve?
Could you explain this to me like I'm an idiot? Explaining what I said above, I want to be able to create a sine wave with one 'period??', calculate the arc length, then create another wave with two periods with the same boundary and the same arc length. So the amplitude will be less on the...- Raavin
