His only point is that when designating this in a circuit diagram the convention is to show which way positive current flows, even though what's providing the currents are electrons which are moving in the opposite direction.

We are not on the same page here, which is not unusual when I make a statement on the thread that a engineer wants to parse, which is what they do with a BLT sandwich or anything that anyone says.

I simply mentioned the hole theory. Nobody really cares which way a electron moves in a circuit diagram, because you just need to pick one way or the other to make calculations. In the field, it helps if you wire the power supply correctly.

Here the deal! I had a exchange up the thread with another FReeper, in which we marveled at the amount of things we know and more importantly, what we don't know.

You guys jumped in and blasted the statement referencing what we don't know, as if to say we know all we need to know and have known it for a while.

My contention holds that we don't understand enough to pick our own nose on a variety of subjects. Only a fool would say we know enough, when in fact, we only know enough to be dangerous.

Your commentary on electrical flow is a great example. Electrons move radially, only because of the atomic structure of the conductor. It is the way the atoms are stacked that causes the radial movement, and the end result that a signal applied to one end takes time to get to the other because it travels a much greater distance then that of the wire length. You think we know it all, yet we have yet to produce efficient conductors without dicking around with gold and copper.

Currently, much work is being done to make better conductors that are constructed similar to a polymer chain and will increase signal speed dramatically. We don't yet know how. We don't yet know a lot of things, like how to transmit raw power wirelessly. We cannot even create efficient and safe power economically without putting in more than we take out, excluding nuclear.

So here I simply state the obvious and you all want to parse it.

You cannot parse the truth. The truth is, we are in the dark ages on many levels of development.

All the hundred year old understandings notwithstanding.

The truth is, that we should know that we don't know a great deal....

That's the truth.....Parse it......If you can.

Exactly. That was entirely Physicist's point, which is why your objection made no sense. That was my point.

which is not unusual when I make a statement on the thread that a engineer wants to parse, which is what they do with a BLT sandwich or anything that anyone says.

I'm not an engineer, I'm a physicist. Physics requires clarity in definition, just like any other science. I'm not sure why you oppose that.

You think we know it all

Apparently you are only here to argue. Rather than actually reading my posts and responding to what I wrote you have instead responded to what you wish I wrote. If you reread my first post to you I clearly stated my agreement with your premise that there are many things we do not yet understand. Where I take exception is with your specific examples of what you don't think we know. You have used examples which Physicist and I know are already understood in the physics community. No offense, but as an electrician you probably don't know enough physics to tell two physicists what physics is and is not known.

, yet we have yet to produce efficient conductors without dicking around with gold and copper.

Again, you have confused engineering and physics. Is it hard to build an efficient conductor? Who cares? That is irrelevant to our physical understanding of ideal (and imperfect) conductors. If you want to talk about building something talk to an engineer. Gold and copper are not perfect conductors. So what? That has nothing to do with our understanding of conductors.

We don't yet know a lot of things, like how to transmit raw power wirelessly.

Again you show your misunderstanding. Transmitting power is easy. Microwaves are one way. Theoretically we know exactly how to do it. If you want to implement it though, go talk to an engineer and have him try to build one. Regardless, the theory is all understood just fine.

We cannot even create efficient and safe power economically without putting in more than we take out

Ever hear of a little law called the conservation of energy?
