Physics is My Specialty

Since I don't have my journal, I'll just have to make do. I'm sorry if the stuff I record here doesn't make any sense to you, but it does to me.
I don't want to start forgetting again...
F = 96 485.339 9(24) C/mol
F=Avogadro's number times the elementary change of an electron (e)
Avagadro's number= 6.022x10 to the 23rd power mols to the negative one power
e= 1.602x10 to the negative 19th power C
m=(Q/F)(M/z)
m is the mass of the substance altered at an electrode
Q is the total electric charge passed through the substance
F = 96 485 C mol-1 is the Faraday constant
M is the molar mass of the substance
z is the valence number of ions of the substance (electrons transferred per ion)
Using Eddington-Finkelstein Coordinates (V, R) removes (?) the singularity at R=2m As R gets smaller - Light Cones tip over.
Oh, and by the way...could I stay somewhere with any of you? I don't really like walking around these streets, if you know what I mean.

Date: 2009-04-21 07:54 pm (UTC)Are you a scientist, too?
she understands more about physics than I ever will |D;
Date: 2009-04-21 07:59 pm (UTC)Yes. My concentration was bio-genetic engineering.
no subject
Date: 2009-04-21 08:02 pm (UTC)I've read about singularities. Don't those exist only in black holes?
Same goes for me and Dan here >>
Date: 2009-04-21 08:04 pm (UTC)I had a couple coworkers in Oxford- it's a college- who dealt with genetics.
I have some understanding of biology, but my interest was mostly geared towards physics.

Yes, singularities do exist only in black holes, but it can be proven that they exist in the space-time continuim as well.
no subject
Date: 2009-04-21 08:14 pm (UTC)Oh! Light cones are mentioned in this book here. It's the hypothetical cone formed by all the information that can reach and be reached by a particular point in space-time, right? What does it mean to say that they "tip over"?
So then is m=(Q/F)(M/z) an equation describing a singularity?
no subject
Date: 2009-04-21 08:20 pm (UTC)Well, physically, the tipping of the light cones is an indication that timelike observers traveling across the horizon cannot escape back out beyond the horizon. In general relativity, an event horizon is a boundary in spacetime, an area surrounding a black hole, inside which events cannot affect an outside observer.
And the m=(Q/F)(M/z)is the basic summarization of Faraday's (no relation) laws of electrolysis.

Oh, I see! That's a good way to visualize it...
Electrolysis? Oh, I need to go look that up...

Date: 2009-04-21 08:30 pm (UTC)I just wonder; where did you learn this? Because even most of the people I know have no idea what I'm talking about most of the time.

Date: 2009-04-21 08:39 pm (UTC)I didn't understand those concepts until years of practice and hard studying.
By the way, the name's Daniel Faraday. I'm sorry if I didn't introduce myself before...I was rather caught up in the discussion of science.
no subject
Date: 2009-04-21 08:40 pm (UTC)That's okay! It's very nice to meet you, Mr. Faraday. My name is Fletcher Tringham.

Date: 2009-04-21 08:47 pm (UTC)Books are good! Yes, sometimes some of the stuff they say isn't quite right, but that is why the world has scientists- to prove or disprove the theories out there.
And so, your world also has chemistry? It's odd how so many worlds have similar concepts...the theory was in my world that if there were any other worlds besides ours, they would be absolutely different in all aspects.
no subject
Date: 2009-04-21 08:50 pm (UTC)It's not exactly the same. I guess in most other worlds, alchemy never developed the way it did in my world. For us, chemistry is just a part of alchemy, which is the process of understanding, breaking down, and reconstructing matter. Do you have that in your world, sir?
no subject
Date: 2009-04-21 08:57 pm (UTC)No, alchemy was a part of science in my world, but only way back in our world's history. It isn't used any more, since all that "turning iron into gold" didn't really result in anything- as such, some people died when they ingested poison which they thought was the "Elixer of Life".
So, how does alchemy work in your world, by any chance?

Date: 2009-04-21 09:03 pm (UTC)The Philosopher's Stone... nobody's even sure if it really exists.
no subject
Date: 2009-04-21 09:09 pm (UTC)Of course, sticking to the atom theory, the reason why you can't change another element into another is because of the atoms- each atom has it's own number of electrons. So technically, gold can never be turned into silver, for example.
But...then how would you change iron into gold, then?
The Philosopher's Stone doesn't exist in my world and probably never will. However, that doesn't stop anyone from writing stories about it.
no subject
Date: 2009-04-21 09:14 pm (UTC)I'm not sure how changing one element into another works. It might involve splitting apart the nuclei, but if that's how it works then from what I've read there must be a major difference between the laws of physics in my world and in this world... I can ask somebody when we all go home, but I don't know if there would be a way to transmit that information to another universe.
The stories I've heard about the Philosopher's Stone say that it's able to help alchemists bypass the laws of equivalent exchange and conservation of matter. I've heard that there have been imitations made that helped to that end, but they were never as strong as the real thing was said to be.
no subject
Date: 2009-04-21 09:21 pm (UTC)Splitting the nuclei of an atom is rather catastrophic- although there are known smaller entities within the nuclei itself, harnessing all the power within that nucleus is rather impossible.
We've even used the power of the atom in bombs- they can blow up entire cities, and even the ones who survive that are pelted with the worst radiation.
It is possible, though, that the laws of physics differ in different worlds...there may be even a world where there is no gravity.
Hmmm...so that Philosopher's stone is like a substance that doesn't quite follow the rules of alchemy? I wonder what such a stone would be made of.
no subject
Date: 2009-04-21 09:30 pm (UTC)Don't talk too loud about those bombs too close to the ears of our military. They already have alchemists on the payroll as human weapons, they don't need to get someone to split the atom on the battlefield.
A world with no gravity wouldn't exist. At least, according to some things we've read here.
You and every alchemist in the history of our world has asked that question. Who knows when we'll find the answer?
no subject
Date: 2009-04-21 09:34 pm (UTC)I'm not sure about whether there could be a world without gravity. According to the hypothesis that says it's a bending of space-time, such a universe would have to have no mass. But that could be wrong, considering that what I've read says that hypothesis doesn't work with quantum mechanics (I don't get any of the stuff I've read about quantum mechanics, though).
no subject
Date: 2009-04-21 09:39 pm (UTC)Well, we can also make artificial gold. But it doesn't really have anything to do with alchemy; we just make a metal and color it gold, and sell it.
Human weapons? Dear me, scientists as human weapons? That must have been a sad day indeed when your country decided to do that.
True, our laws of physics state that such a world wouldn't exist. But who knows? I've been surprised to find many things that have challenged my perception of other worlds since I've gotten here.
Me, an alchemist? Well, I'm more of a scientist. But, in your world's case, I am an alchemist, I guess. And yes, there are too many mysteries in the world that we will probaby never find out.
Such is the futility of mankind...
no subject
Date: 2009-04-21 09:42 pm (UTC)Well, if I do remember from a book I've read, if life existed in two dimensions, it would have no mass. But such a world doesn't exist, at least not yet...
I'm a little fuzzy on quantum mechanics, so I have no idea if that hypothesis works ith it or not.
But, I just have to believe that the only law of physics the worlds share in common is the law of gravity.

He snaps with them, creating a spark. The circle isolates the oxygen in the air to create explosions. It has to require an immense amount of concentration to do that to the molecules. No one has been able to replicate it.
No, you're a physicist. I should mention that our asylums have a rather high population of them.
