Sometimes I Feel Like A Logarithm
Where we learn that we each have an internal power function ready to bust out.
Let's begin with this excellent definition of what a logarithm is:
Logarithms are mathematical relationships used to compare things that can vary dramatically in scale.
I find that the clearest way to explain what a logarithm is is to first say what its relationship is to an exponent, because the word exponent (noun) and the word exponential (adjective) are much more familiarly used in our daily lexicon. An exponent is that tiny hanger-on up in the top corner next to a base number, dictating how many times that base number should be multiplied by itself:
34 = 81
Exponents do their work pretty quickly - you know, exponentially đ- and I feel like their drama is so In Your FACE just because their operation feels and actually gives a visual impression that is practically instantaneous. You know the type.* Itâs like, Mr. 4 Exponent showed up, located where 3 was in the room, and then he jumped high and stood on that table and attached himself to 3, and then - where there was just 3, whooooosh! Boom! 3 is now 81!!
The inverse function of an exponent is a logarithm, so it essentially performs the opposite function of the exponentâs operation. That logarithm is the undoâr you invite when things are overwhelming, when youâre starting with a big number and you just need to compress and make things manageable (again) so that you can pause, take a breath, and get a sense of gaining (back) some control of the situation at hand.
That same example above but now in logarithmic form looks like this:
Log3 81 = 4
So, if your goal is to control that whoosh! Boom! situation at hand that Mr. 4 Exponent has just wrought upon everyone, then youâd invite Ms. 3 Log, whoâs going to calmly come in and take a seat next to where 81 is standing (who is taking up a lot of space in that room) â and just like that aaaahhh, 81 is gone and 4 is now like all the other base numbers in the room; they're not standing on a table nor are they sitting on a chair, and 3 is back to how they were as if they never met that Mr 4 Exponent guy.
You see - where the exponent is blowinâ things up, the logarithm is like, letâs do deep breath exercises, namaste.

The word logarithm was coined by the Scottish mathematician John Napier,* from the two ancient Greek terms: logos meaning proportion, and arithmos meaning number.
A few years back, mathematician Steven Strogatz wrote a series of math essays for the New York Times, and in his essay titled âPower Toolsâ, he gave an explanation for the very existence of logarithms.
We need them because itâs always useful to have tools that can undo one another. Just as every office worker needs both a stapler and a staple remover, every mathematician needs exponential functions and logarithms.

When I read that, I realized that sometimes I feel like a logarithm.
Itâs definitely how I feel when I am starting an organizational evaluation of a companyâs framework. In my initial steps, as I collect representational data from across the breadth of an entire company, I bring it down to a manageable state for clear universal understanding; I compress the information. That being said, I donât omit any information because I know that itâs imperative for the final analysis to not minimize-the-existence-of the parts that make up the greater whole and all (the people) within it.
Another thing about logarithms is that the general public isnât very familiar with them, certainly not as familiar as they are with an exponent. You know youâve seen a Superscript used in an equation, perhaps when you were reading about the spread of an infectious disease, but how often have you seen a Subscript in a news article? We usually have an innate preference towards the visually familiar, rather than spending the time it might take to comprehend something new. We might even be dismissive about the thing we arenât familiar with because why take the energy to be curious about that new thing if the familiar thing will serve the needs well enough? We make conclusions that itâs probably of lesser value.
And thatâs another reason why I sometimes feel like a logarithm; itâs when I realize Iâve been underestimated by others.
Like the Superscript and Subscript examples, sticking with what you're familiar with is easy, especially if your reference points for the unfamiliar canât be updated without some substantial time & effort. Iâm constantly surprised how some people will say they are curious and want to learn about a human identity that theyâre unfamiliar with, yet - in reality - the patience and time needed to unlearn a belief is devalued. So, a bias (implicit or explicit) is developed, usually from some mass impersonal reference point, for that unfamiliar thing - and definitive conclusions are made. I have been immediately underestimated because I look younger than I am (which, to some folks, then equates to being inexperienced), or because I have visible tattoos (and you know what that means đ), or simply because I am a woman ( đetc ).
Or, sometimes I feel like a logarithm because of its power of perception.
Inline with those assumptions that are based on biases, perception is a close relative. In the 2014 edition of âThe Best Writing on Mathematicsâ book, an annual publication of math essays* that is edited by Mircea Pitici, right from the beginning of the essay âWhy Do We Perceive Logarithmically?â written by Lav R. Varshney and John Z. Sun, the authorsâ setup is spot-on:
Why do small children place 3 halfway between 1 & 10? Why do two lightbulbs not seem twice as bright as one? Why do we perceive logarithmically?
What struck me in their essay is when they explain a term that I had never heard before - psychophysical - which is a branch of psychology about the direct relationship between our internal / mental processes (the psychic) and our external / stimulation processes (the physical), and how the default conclusion we tend to end up at is logarithmically based. Further explanation from the essay:
âBut in fact perceptual systems of all kinds display a non-linear relationship between external stimulus and internal representationâŚIf we double the force on your hand, it will feel like* less than double the pressure. If we double the salinity of water, the taste will not be* twice as salty.â
The reason we (all) tend to do this sometimes is because âwe do not notice absolute* changes in stimuli; we notice relative* changes.â Whatâs happening is that we perceive what we see and hear logarithmically.
This personal logarithmic perception realization may be more about me being a logarithmic interpreter. When I worked in 3D animation, Iâd often be the go-between an artist and a client. A client might ask for the artist to âdouble the yellow color.' And the artist would go ahead and double the intensity of that color, and weâd send it back to the client for review, and then the client would invariably say something like, âyou didnât double it, I barely see the difference.â
And thatâs how those of us in the studio learned that when thereâs a numerically-related direction made to an artist, before any action is taken, weâd ask the client to rephrase their direction descriptively. Thatâs when we would hear something more like, âmake the yellow more intense and saturated, like, âŚtwice as much as it is now.â Aha! And you know what the artist would do? Theyâd bump up that yellowâs intensity not by 2x but by 4x. And then they'd eyeball it and see if they'd need to do even more in order to give the perception that the color intensity was doubled.
Just like the essay writerâs example above, âWhy do two lightbulbs not seem twice as bright as one?â, the second lightbulb doesnât appear to double the brightness of light in a room because our eyes process changes in lumination logarithmically. So, just as weâd need four lights of equal lumination to perceive double the brightness, weâd logarithmically bump up the intensity of the yellow to have it appear to be âtwice as yellowâ as it was before. Hence, bumping it up by (at least) 4x.
As it is thought by a cat* thatâs sleeping with their paw over their eyes so you canât see them cuz they canât see you- â but, yeah no, I SEE YOU CAT â a logarithmâs power already exists within you. Itâs ready to be used as a way to bring compactness to an overwhelming situation and it exists as an equally powerful component to all those âquick growthâ seekers. Sure, you may need to knock down some existing biases or provide more explanation behind the benefits of this power, but then thatâs the opportunity for you to own the very definition of your identity and of who you are.
Thanks math, you're the best.
