Socratic Coffee on why particle size matters (Part V: signal-to-noise ratio)

At this point in our series, we’d like to introduce a framework we think is very useful when it comes to brewing and tasting coffee. You might have heard the term “signal-to-noise ratio” (often abbreviated to SNR). With a SNR framework, the world can be thought of as containing stimuli we are interested in (signals) mixed with stimuli we are not interested in (noise). SNR is the ratio of signal power to noise power. Read more

Socratic Coffee explains why size matters

There’s one quote from American astrophysicist Carl Sagan we at Socratic Coffee really appreciate: “What counts is not what sounds plausible, not what we would like to believe, not what one or two witnesses claim, but only what is supported by hard evidence rigorously and skeptically examined.” Read more
