Who coined the term "signal-to-noise ratio" and when did statisticians start using the term "noise" to describe randomness?

You are looking at relatively recent references. Noise originally comes from telecommunication analysis in early 1900s well before Shannon; basically, the electrical noise was heard as audible noise- ...

Did Ronald Fisher ever say anything on varying the threshold of significance level?

Jerry Dallal collected some of Fisher's quotes from various works. And Fisher said too much, first setting the P=0.05 cutoff in 1925, then not following it himself, and, finally, openly advocating ...

Why do many names of technical and scientific subjects end with "ics"?

It is not random. These names are of Greek origin, and -ic or -ics are Anglicizations of the Greek suffix -ikos, which meant "pertaining to". In other languages it can be rendered as -ika or -ica, ...
