2 op amp followers on 2 capacitor plates not measuing correct voltage
the capacitor is not grounded. So it is floating. Each voltage follower just follows the voltage on each individual plate. I guess the circuit works. I found some wire problems and fixing that seemed to fix the problem with not showing the correct battery voltage. I think the problem with...- dustinthewind

2 op amp followers on 2 capacitor plates not measuing correct voltage
On 2nd thought berkman I might understand what you are saying. I'll try what you are telling me and see if that works too.- dustinthewind

2 op amp followers on 2 capacitor plates not measuing correct voltage
The documentation states it will run on 1.8 to 5.5V if you read the 2nd page of documentation both in "features" and "general description". The fact that each of them follows voltage indicates they are working working. The problem is they will not drop below 9 and 16mV amp 1 and 2. If...- dustinthewind

2 op amp followers on 2 capacitor plates not measuing correct voltage
I am currently trying to measure an 80pF capacitor using 2 voltage follower op amps. I have them both powered by a set of 2 1.25V rechargable batteries. They are op amp type LMP7721 link: http://www.ti.com/product/lmp7721 . Each op amp is configured such that the voltage out terminal [end...- dustinthewind

Graduate Visualization of space time contraction and gravity
I believe when you go to post you have to select advanced mode for it to take. I ran into the same problem. I also wanted to say thanks for your helpfull tips. It got me thinking about other ways of looking at relativity.- dustinthewind

Graduate Visualization of space time contraction and gravity
Thanks for separating the terms. That let me know there was a difference so I looked it up. I get this from http://en.wikipedia.org/wiki/Relativity_of_simultaneity or the Relativity of simultaneity. And this equation t’=\left(t-\frac{v x}{c^{2}}\right)\gamma Where you take an object and...- dustinthewind

Graduate Why the black hole density is called the infinite density.
So let me know if I read you wrong. But it looks like you are suggesting then that the event horizon stops moving as soon as it reaches the outer surface of the object its engulfing? I would guess as this event horzon is expanding there is some reduction in the radius of the object? But it...- dustinthewind

Graduate Why the black hole density is called the infinite density.
Ok yeah I was referring to an outside observer referring to the black hole in a frame equivilant to the frame of the black hole's motion if that is appropriate. I guess it is unusual to combine quantum mechanics and general relativity. And its just speculation on my part but it didn't seem...- dustinthewind

Graduate Why the black hole density is called the infinite density.
If you think of it in terms of space time contraction as the matter reaches the speed of light it becomes flat. However no matter can be infinitly flat as if we know its speed exactly we are uncertain about its location by \Deltax\Deltap\geq\frac{\hbar}{2}. This alone would give the in falling...- dustinthewind

Graduate Do Photons Have Mass? - Debate & Questions
The way I came to understand how photons can have mass and yet have no mass is that they have apparent mass because of their energy. You can calculate their energy as stated above E=\hbar\omega. So then I always took E=mc^{2}. And sovle for the mass of the electron. You can then consider it...- dustinthewind

Graduate Visualization of space time contraction and gravity
I am glad for a place like this where I can come to discuss what is on my mind with those interested. My delema is expanding my conceptual understanding of relativity and how it realates to space time and gravity. To begin I will go over how I have come to understand space time...- dustinthewind

Graduate Neutrino Oscillation <-> Neutrino Mass
This is an old post but I just had to fix this. Here is the reason they assumed they had zero mass. It is in this paper here, http://hitoshi.berkeley.edu/neutrino/PhysicsWorld.pdf . "Since right-handed neutrinos have never been detected, particle physicists concluded that neutrinos had to be...- dustinthewind

Graduate Explaining the O'Hare Airport UFO (day events)
Well that is interesting it might burn back the clouds but there is still the issue of the metallic reflection, and a solid object rotating, and the sudden accelerations. Hot air once released should reach terminal velocity quite quickly at a relatively low speed.- dustinthewind

Graduate Explaining the O'Hare Airport UFO (day events)
I personally think you are going to have a couple problems explaining a few things. *The metallic color. *A solid shape that rotates. *That it is stationary over the airport at set distance then suddenly accelerates at a drastic value. *The power necessary to to deflect the cloud cover...- dustinthewind
