In fact, your common solid metals develop surface layers of metal oxide under atmospheric conditions. Aluminum, tin, iron, copper, they all have oxidation layers on their surfaces. They're typically salt-like, crusty materials, technically ceramics, as they're held together by non-chaining covalent bonds. If you got a thick enough layer of it, you might be able to get a little plate of it, like you could with rust, which is an iron oxide.
>>10008267You're just being dumb at algebra. Two of your KCL equations give you expressions for i6, and two of your KVL equations give you two more expressions for i6, so start by replacing i6 with shit. Then, replace another current value in terms of the remaining variables. Keep going until you're left with only one current value, such that the resistance and voltage variables are all in one equation. From that first expression, you can suss out the other 5 by just replacing them with KCL equation equivalents.
>>10008486Public education is a manufacturing process where the product is employees. Its goal is not to influence IQ, because IQ is the rate at which one learns, not the amount of information one can access. Public education eases use of the information that employers require their product to access. However, when your process is not producing a quality product but there is still a clear demand for that product, do you scrap the process entirely or do you look for ways to improve it? Albeit, the investment shouldn't be in the teachers so much as it should be in better, more open educational research.
