Citations are not quotations(!?)
By citations, here we mean the process of referencing the source of a statement/result, etc.
This (Ref. [1]), for instance, is a citation for Einstein's famous quote:
Everything should be made as simple as possible. But not simpler.
It turns out that the original is more along the lines of:
It can scarcely be denied that the supreme goal of all theory is to make the irreducible basic elements as simple and as few as possible without having to surrender the adequate representation of a single datum of experience.—Albert Einstein, in a 1933 public lecture, according to Alice Calaprice [1].
On this website, we use the template {{cite|...}} to cite works, as explained in this blog post.
The page must thus ends with
= References = <references />
For good practice it is better to cite from our bibTeX database sci.bib bur if for some reason one does not want to do that, then use the <ref>...</ref> instead.
