Unfair. The USA is treating its own citizens awful as well.

With higher carbon levels will there be a better RUBISCO? I always wonder how nature could make such an atrocity.

They are cuddling in the book. These days one might suspect romantic feelings because of that but I think for Tolkien it really was just about friendship. It’s toxic masculinity that physical contact is only allowed in a romantic setting.

You can’t swap the genders in this comic strip. Think about that what you want.

Ah yes, the world will collapse because of a problem that is almost exclusively in the USA.

On an unrelated note, have you ever heard of Americentrism?

With one layer the case is simple. There is a certain light energy at which the conversion of light to current occurs called gap energy. If the light energy is lower than that no conversion can happen and if the light energy is higher the extra energy is converted to heat and only gap energy remains.

Filtering UV would be a loss but a small one.

I would be grateful if you could include the country this applies to in the title.

For everybody else: it’s the US. Who would have thought.

I’m on the otters side here, semiconductors make no sense. For example the Fermi-Energy is supposed to be in the middle of the band gap but how that’s just idiotic. Fermi-Energy is the point up to that we fill electrons but inside the bandgap are no states. Like defining the properties of an electron that doesn’t exist.

I never understood BRICS. Sure, they are the second line of industrial powers (China?) but especially India Russia and China hate each other to the bone. They are partners only on paper. If someone can explain it to me please go on .

I’m a physicist. If you are an engineer that sounds like a “you” problem.
