If you have read the blog post it's a difference between the chemical symbol Ge and Gr, which as I understand is what you would refer to as a "semantic error".
Likely because the original paper references Ge, and Germanium has an "r" in it and Gallium does not
I'm with the OP on this one - there is no "Gr" so it's very obviously a typo. Still worse than no typo, but better than if they wrote Ga.
That said, these articles should be issued corrections...
I think the reader and the writer share the burden of accurate communication. The reader should ideally come prepared and the writer should provide as best they can. A prepared reader makes quick work of this typo.
"Pi" is only capitalized at the start of a sentence.
"no one would give it a pass" is a logically unsound claim, given the number of people on the planet.
How very absurdly wrong of you :)
I’m not. If somewhat said Pi was 9.14 I think no one would give it a pass. It’s not like a misspelling. It’s an invalid element which is the chemistry equivalent of an absurdly wrong number in maths.
