A small selection of paintings from the Quarantine…

Here are a few of the many, many paintings I have made during the coronavirus quarantine. A lot more can be seen at my on-line gallery at

I will have an exhibition in Berlin sometime when the restrictions are finally lifted…

Charlie and Fitzroy and the very strange bugs

Dear friends,

After a VERY long Corona hiatus, I am finally adding some new material to the blog! The first entry is “Charlie and Fitzroy and the very strange bugs,” a book for children about evolution.

First comes the English edition; German will follow soon.

There are a few pages of notes for parents and teachers at the end. The book is targeted for grade-school children; it probably works best for kids aged 7 to 11; I’d greatly appreciate feedback on your experiences with it.

The basic idea is that there is evidence for evolution all around us, if you just know where to look. While exploring the woods near their house, Charlie and her dog Fitzroy discover some strange bugs. By watching what happens to them over the next weeks and months, they stumble on the basic principles of evolution. Along the way they meet a strange old man who has thought about this for quite some time…

I will also have a few printed copies for sale soon.


Finally an update to the Devil’s dictionary! Today’s words: vitalism, homunculus, -ify

See the complete Devil’s Dictionary of Scientific Words and Phrases here.

vitalism  an outdated view of life that was ultimately supplanted by materialistic theories such as evolution and the billiard ball model of the universe. Vitalists held that inorganic substances such as water or black coffee had to be perfused with a spiritual energy to have any kick to them. Vodka or whisky worked best.

homunculus  a miniature person postulated to exist somewhere inside a normal human being, probably in a tightly folded form. A homunculus is smaller than a dwarf or gnome, more on the scale of an elf or fairy, but larger than a blood corpuscle. Natural philosophers considered the existence of homunculi essential because without one, how could a physical body make decisions or move its limbs – for example, to answer its cell phone? They reasoned that there had to be a tiny person inside who makes all the decisions and pulls the strings: a sort of Mission Control, or Wizard of Oz, or perhaps a product made by Apple. The homunculus theory lasted quite a while until someone pointed out that the homunculus, too, would have the same problem – it, too, would require a wizard or some other being to tell it what to do. This led to the unhappy theoretical conundrum of infinite recursion, otherwise known as “it’s elephants all the way down.” To solve the paradox some bright bulb proposed that the body of the homunculus contained a Philosopher’s Stone, a sort of smart rock. How it got there is unclear; probably the elf or fairy had to swallow it.

Some people give their homunculi names, like “Bob” or “Ezekial”, or “my little Princess.” In Boston, for reasons that are unclear, everyone’s homunculus is named “Herman.” This explains why they pronounce the word “hermunculus”, or in extreme cases, “hoimunculus.”

-ify  a suffix added to a word and thereby transforms an object into the thing that the suffix is attached to, whether it wants to change or not. What it was before the transformation is anybody’s guess. Liquify, for example, describes the process of making a liquid out of something that shouldn’t be, such as hair, or a motorcycle. Solidify, by contrast, creates an unnatural solid. An example of solidification is to turn cream into butter and then carve it into a life-sized replica of Leonardo da Vinci’s Last Supper, or perhaps a sculpture of a cow – which is creepy, akin to some form of cannibalism or incest.

Other uses of -ify include:

pacify – to make something such as a screaming child peaceful, usually either by sticking a silicon or rubber object in its mouth, or by shooting it (contrast with Peacemaker)
mortify – to exhibit such poor manners that you kill someone
petrify – to scare something so badly that you turn it to stone
classify – to force a bunch of unruly objects – such as first graders – into a group, despite their protests
crucify – to force people to stand for very long periods of time with outstretched arms, sometimes using a wooden structure as a support
clarify – to take something murky and extract everything of interest until it becomes so transparent it is practically invisible
ratify – to turn something into a rat
carrotify – to make a carrot out of something that was never meant to be one
satisfy – to disrupt a person’s natural state of grumpiness and render them content, usually only very briefly
edify – to rename someone Ed (not to be confused with edwardify, edwinify, etc.)
codify – to turn something into a type of fish that sucks on the mud at the bottom of lakes or oceans (contrast with catfishify)

Fresh from the Quarantine: An image of the Coronavirus

It’s been a long time since an update – I know! Sorry! But I’ve been busy and the drought is now officially at an end.

I’ve just finished a new painting of the coronavirus interacting with a human cell…

I’m offering it freely to anyone who would like for any non-profit publication or other use – just cite the following:

Artwork by Russ Hodge,

I’ve done a lot of painting during the quarantine and will be posting it soon at my on-line studio:



In case you haven’t seen it…

In case you haven’t visited the site in a while…

I am posting my artwork now on my new “studio” blog. If you like the non-scientific artwork, check in there from time to time. A couple of the newest pieces are below.

And for those of you in the Berlin area, I’m giving a concert and having an exhibition of my paintings in Neukölln in mid-March… If you’re interested in attending the concert, space is limited, so drop me a line and I’ll reserve you a seat.

Tell your friends!

Both events are hosted by the Wunderkammer; check out the rest of their program at the Wunderkammer website.

An update to the Devil’s dictionary: WORMS!

See the complete Devil’s Dictionary of Scientific Words and Phrases here.

all entries in the Devil’s Dictionary copyright 2020 by Russ Hodge

worm   Worms belong to the family Wormidae, which is the Latinate designation, although the word “worm” descends from the Old Lower High German Wurm, which meant dragon, suggesting that the species have undergone a significant reduction in size and a few other changes over evolutionary time. There are two major classes of worms, each of which consists of about a zillion subtypes. These are arranged in subclasses, at least theoretically; in practice, no two scholars agree on the criteria by which this should be done. It’s a good thing for wormologists: if they could solve the problem it would put most of them out of business, since most publications on worms have to do with taxologies. The major classes are the flatworms, or Flatidae, and the fatworms (Fatidae). In the historical literature one sometimes sees the nomenclature Flatulae and Fatulae, but these terms were modernized because they couldn’t be used without provoking hysterical laughter and confusion. To tell the difference all you have to do is step on one. A Fatidae will make an audible, somehow satisfying popping sound when you apply weight to it, whereas a Flatidae will hardly be perturbed at all. In fact, some subtypes of Flatidae are almost impossible to kill – you can chop them up into pieces and they regenerate entire worms; eat them and they take up residence in your gut; apply a flamethrower and you’ll probably burn down your lab before you kill them. This would pose an immense overpopulation problem except that Flatidae are so thin you can stack a million on top of each other without the pile getting appreciably thicker.

The unifying characteristic of worms is their lack of legs, which might cause them to be confused with snakes, except that they also lack teeth. As a means of locomotion, they draw on the musculature of their digestive system, which is basically a tube that starts at the mouth and ends at the tail – although it takes an expert to tell the difference, and even worms sometimes get confused. Basically, worms are intestinal tubes that lack limbs and other unnecessary embellishments.

Worms have an important ecological function, as the biological equivalent of Roombas. They creep along the ground and suck up anything in their path. Molecules inside the worm digest the stuff they eat and transform it into soil, which plants require to grow. (Providing the worm is headed in the right direction. If it moves backwards, the process is reversed.) Plants transform the soil back into worm food, which is their major function. All of this requires lots of energy. Environmentally speaking it would probably be more efficient simply to eliminate the plants, but then the worms would just get into mischief.
