No, the plates still are the full set from when I moved out.

I normally do use ceramic plates at home. But I guess the widespread usage of metal plates here, is due to the fact that they're cheap and easy to maintain. Also, dishwashers are quite rare over here.
@Blue I don't think there's anything wrong with using metal plates, but I'm skeptical about the practical advantage - I wouldn't have expected metal to be cheaper than ceramic since it has to be quality steel (right?) and I'm not sure how ceramic would be harder to "maintain"

@ACuriousMind Uh, no. They're not really made of "quality steel". They use cheap metal plates in the local shops
But what are they made of, then? You can't use something like nickel or copper since that would get into the food (right? Please tell me these don't poison your food...)
@JohnRennie But they're coated/seasoned - you don't actually get the iron exposed to anything if you're doing it right
I'm just skeptical this is in any way easier than using ceramic plates that don't corrode at all, but if the plates are made of cheap steel then I can see the price argument
Huh, it appears ancient India has long been a major center of steel production, which might explain a traditional inclination to produce household items from it
Whereas the Europeans only caught on later and tended to not make anything out of steel where it didn't provide a significant improvement, I guess?
@ACuriousMind In early and medieval Europe ceramics were very popular, from what I know. Similar in China. So probably the tradition has just continued
@0celo7 I don't think there's a special word for that since most will also tell you that you can add arbitrary constants to the Hamiltonian without changing the physics
@curiousmind: what do you think of the Ahranov-Bohm effect thats supposed to show the existence of a gauge potential as being fundamental rather than the E & B fields?
@MoziburUllah Yes, you can introduce gauge-fixing terms into gauge theories, but that's not really the best indication that you have a gauge theory on your hands - the clearest indication is the solutions to the equations of motion being non-unique.
@MoziburUllah I think it shows less than is commonly claimed - since it doesn't indicate the importance of $A$ itself but merely of line integrals of it over closed curves, which is the flux through the area bounded by such a line - but together with the fact that a least action formulation in terms of $E$ and $B$ instead of $A$ is very ugly and infeasible I think it's enough to show that we should think in terms of $A$, even if we don't, strictly speaking, need to.
@ACuriousMind Now that I just had my dinner, I think it is due to the fact that Indian cuisines are more "wet" and varied that we use metal trays rather than ceramic plate
@0celo7 @bolbteppa "Minhyong Kim wanted to make sure he had concrete results in number theory before he admitted that his ideas were inspired by physics."
'Math needs physics ideas but certainly not the physics language' so the guy thought it up using physics ideas, but not using the language, makes no sense, you are saying the language he used to think it up is irrelevant when he needed that language to even think it up, it's a ridiculous thought
@MoziburUllah it's the same language, e.g. tensors is a great example, old notation vs. linear algebra notation, same thing though people seem not to see it and really get angry at the old way
@JohnRennie So I had a discussion with a British prof of mine, he said that one should use a z for "realize" because it's closer to the original Greek.
It's amazing trying to read math in another language and using some of the tricks that exist which really work to help you understand the meaning of words by deconstructing them, stunning how far you can go
Because so many words were inherited in languages like French and English from some old languages, and also because a lot of words in math/physics were taken from Latin/Greek, means a huge proportion of words are decipherable through tricks which is very helpful
Maybe I should give it another go. I couldn't get into Marquez's A hundred Years of Solitude, but a couple of weeks ago I opened it up and found myself liking it.
@BalarkaSen: not sure - but its a cool word to throw around...
@BalarkaSen i started listening to noise cuz since i was a synesthete sometimes i just wanted to drown out everything where normal songs always had distinct shapes or colours
