Wordplay Wednesday: Oxidation and Reduction

As a geologist, I use the words oxidation and reduction a lot. For example:

These rocks have gone through oxidation.

Or this rock contains reduction spots.

But what do I mean when I say these things? Primarily, this has to do with iron and its properties (but other elements can be oxidized or reduced too). Iron is super reactive with oxygen, like best friends who go everywhere together. However, what iron isn't aware of is that oxygen isn't a good friend.

Reduction is the opposite of oxidation. It is the gaining of electrons. So, if one element is being oxidized, another is being reduced.

Making sense so far? Here is what the reaction for rust (which is what happened to those red rocks above) looks like:

Copper also oxidizes. A great example is the Statue of Liberty.

So the next time you pass by red cliffs you can sound super smart to your friends and family by telling them that those cliffs have been oxidized.

Tune in tomorrow for a look at the father of mineralogy. Fossilize you later!

For my April reduction print, I impulsively decided to try two different colorways, one with full color and one with shades of brown/burnt umber. My Patreon members were sent the full color version, but I also love the monochromatic look?

I'm working on my June print right now, and I'm using the same idea with a gray blue for the species Great Auks :) I'm really hoping it's reminiscent of an old and aged photograph.

Day 3 of solving the 13x13 with corner reduction.

Unlike standard center reduction, we attach edges (wings) to the corners and slot the centers (points) in between them. I'm also attaching centers (crosses) to their respective edges (the center edge) as we go.

So far the main hurdle for each phase has been the crosses around the last 4 corners. I always end up putting them in with commutators, but it's always with a sense of defeat - like I could have intuited it and gave up.

To pair the crosses with center edges and points with corner/wing clusters is just center rotation by π radians (180°, but radians are better). This can be accomplished with the algorithm (RUR'U)×5.

I did the first layer of teeth the same way, essentially reducing the outer 3 and center layers to a 5x5 then reducing that 5x5 to a 3x3. This was surprisingly straightforward but somewhat tedious as there are 2 mirrored types of piece that cannot exchange with each other, but my brain tends to equate them.

I have no idea how I'm going to do the next layer of teeth - there's 2 now that will build out to the reduced corner block. Oh well, one ago a time I guess.

In the following oxidation-reduction reaction, Na is oxidised to Na+ and H+ is reduced to H2 (figure 19.6).
