    KJW liked post by tk421 On thread : potential difference
    If you are talking about Kirchhoff's voltage "law," the reason is as given by x0x. In a conservative field, the net potential around any loop is zero. I don't know if you are yet familiar with vector...

    KJW liked post by Markus Hanke On thread : The Varying Speed of Light
    The benefit is in giving people the opportunity to show why Farsight's arguments are not in accord with current scientific understanding. It is about the points being put forward, not about who is...

    Hmmm...I can at this point now only suggest that you take a very careful look at your own statement above, and consider what is wrong with this. I can't really help you over and above this, given the...

    KJW liked post by SpeedFreek On thread : The God's eye global gist of general relativity
    Well, it was remiss of YOU not to track the conversation back to where it started. Post 83 is quoting only part of post 78, whilst post 78 itself quotes the original statement made by Jilan in post...

    You guys are so fussy. Everyone knows that 6 apples = 6, which is greater than 5 kilograms, and a whole lot greater than 2 volts.

    KJW liked post by btr On thread : Turning light into matter
    I'm afraid that it really isn't a question of interpretation; in QED, the only interactions which can ever take place between charged particles are via the electromagnetic field, and the only...

    KJW liked post by PhysBang On thread : Hawking Claimed Black Holes Exist, Right?
    It's a gross non sequitor to imply that physicis are wrong about an aspect black holes because physicists have been wrong about a radically diffrerent area of physics.

    There is currently an issue with forum software, which I am trying to resolve together with the Site Admin. The problem isn't on your end, but rather with the forum itself. I'll let you know once I...

    They don't need to be changed because they already give the right result. It is very disappointing that people like yourself just ignore the answers that are being given - I have presented both the...

    KJW liked post by Markus Hanke On thread : Why is space infinite?
    I think you are still not grasping the point of what I am trying to say; maybe I am just not explaining it well enough. The first thing you must realise is that the energy you say the photon has is...

    KJW liked post by Markus Hanke On thread : Why did Einstein modify EFE?
    I think what KJW is trying to point out is that in order to actually evaluate expressions such as the above, you need to know the metric, since the Hodge dual ( and the volume integral ) explicitly...

    KJW liked post by Robittybob1 On thread : Some questions about friction
    I think you'll find you are dealing with three different physical situations. The first is loss of traction or friction. The second is work done to clear a path through the flooded road. The...

    KJW liked post by Useful Idiot On thread : Everybody's Got a Theory
    And so what? Just off hand, we might consider science as a means to tell if one idea is better than another, \ instead of asking the Pope. This means we ask nature if your theory describes...
