Part One: Signal Processing
Unlike manufactured systems, our senses can’t rely on highly accurate and linear sensors to convert external stimuli into usable signals. Biological systems are inherently variable, noisy and limited in range, yet we need clear and accurate information to guide our behavior. How do we manage to do this?
This upcoming book took six years of mostly full time effort to write and edit.It was transformative for me, and I hope the information will be for you as well. Here are some of my major takeaways about our amazing chemical senses and the ways they are processed in the brain.
It’s obvious that we human beings are all pretty different from one another—in appearance, experience, attitude, gender, and countless other attributes. Each of us has things that come effortlessly and others at which we struggle. It goes without saying that these differences affect our abilities as tasters. But how, exactly?
Like living organisms, the evolution of beer styles follows a principle called “punctuated equilibrium.” This states that as long as conditions remain unchanging, there is little evolutionary change other than random drift. But when conditions change, entities either adapt or radiates to fit changing niches or gets pruned back as unfit. With long-dormant American beer, changes started in the 1970s.
From the glass on the table to the smells of the beer frothing up, to the sights and sounds of the barroom and beyond, our world usually feels solid and reliable enough. It is an illusion, however—nothing more than a projection created by our highly fallible perceptions. Ancient wisdom makes a point of it; modern science increasingly verifies this unsettling truth.
