Using Google ngrams

I’ve found to be a very handy tool while writing my book. It has helped me answer such questions as which is the preferred term, “bypass capacitor” or “decoupling capacitor”? “bandpass” or “band-pass”? “passband” or “pass band”?

I’m a little old-fashioned and will stick with “bypass capacitor”, but prefer “bandpass” and “passband”.

The tool is not always useful—I can follow the rise and decline of “mho”, but “siemens” has too many other uses to be able to determine when the standard name for the unit of conductivity overtook “mho”. It is rather a shame that “mho” did not become the standard, as it is “ohm” backwards and ℧ is such a cute symbol (being Ω upside down).  I am sticking with the standard in my book, though.

(Sigh, the iframes that had the interactive graphics worked fine in the editor, but when the post was published, WordPress stripped them out, leaving only the links.  You’ll have to click through to see the graphics—sorry about that.)

History of electronics via Google ngrams

I was playing with Google ngrams today (checking to see the whether some variant spellings were ever mainstream) and came up with a history of electronics in one graph:

A short history of electronics in a few key words. At first, power is what mattered, and voltmeters and ammeters ruled. In the 40s, time-varying signals mattered, and oscilloscopes started getting attention. Time-varying signals ruled until digital electronics took over with the introduction of the microprocessor. Now all these low-level views are losing space to consumer-level gadgets like mobile phones.

I could have picked different words, but because Google ngrams provides no way to switch to a log scale for the y-axis (the only sensible way to show growth or decay of word usage), it is not feasible to put a common word like “computer” on the same graph as a rare word like “multimeter”. Google, as always, provides an almost-reasonable product, then never takes the trouble to finish it to allow the user to do things right. Oh, well, it’s free, and that’s the business model Google is relying on: ads on free (almost usable) stuff. The two things they do well are search and selling ads.
