Cloaking from chemicals?

Catching up on some cloaking research that was published after the bulk of my invisibility book was finished — lots of interesting stuff has been happening!

One thing I stress in my discussions of invisibility is that the science and technology is being explored for more than just hiding things from visible light. If we can guide light waves around a central region and send them on their way, we can do similar things with other types of waves. I’ve written before about serious proposals to use cloaking to protect buildings from earthquake waves, and in 2012 a theoretical paper was published about how it might be possible to design cloaking devices to protect offshore structures from ocean waves.

The principles of cloaking have even been used in the design of cloaks for things that are not even waves. A “thermal cloak” was introduced in 2012, which guides heat around a central hidden region, keeping the central region shielded. Similar cloaks have been introduced for static electric and magnetic fields.

I thought I had seen it all when it comes to cloaking, but I was totally surprised when I came across a paper titled “Chemical Cloaking,” published in 2020 in Physical Review E by Avanzini, Falasco and Esposito! The paper introduces the possibility of hiding an object in a fluid flow by using active chemical reactions!

Invisible Monsters, by John Benyon Harris

Another post about invisibility in science fiction! All because I want to make dang sure that everybody knows that I have a book out about the history and science of invisibility!

I’ve seen just about everything in science fiction stories about invisibility. Well, not “seen,” but… eh you know what I mean. I’ve seen invisible buildings, invisible robots, invisible dinosaurs, invisible superheroes, even invisible planets. Let me add to that curious list with a story about what I interpret as… an invisible blob?

The story “Invisible Monsters” appeared in the December 1933 issue of Wonder Stories, another magazine by Hugo Gernsback, the originator of science fiction magazines, who published Amazing Stories!

The title gets right to the point, doesn’t it? No dancing about the topic of this story — it’s about invisible monsters, and you’re going to get invisible monsters!

Invisible One, by Neil R. Jones

Another classic invisibility story reblog, to celebrate (and remind people) that my book on the history and science of invisibility is now out!

skullsinthestars's avatarSkulls in the Stars

Starting to get exhausted by all these invisibility posts! But I’m going for 30 straight days of blogging, then I’ll rest.

The scene:

In her Ohio home on the outskirts of the 26th Century metropolis of Cincinnati, Moira Presby softly hummed a current air and eagerly awaited the return of her husband who had been called away suddenly that evening on promising business. She was as happy as people of the earth were expected to be happy under the joint rule of the Durna Rangue, a semi-scientific cult, and the space pirates.

Okay, so in the future the Earth is being ruled by a semi-scientific cult, and… space pirates???

I must admit that this introduction, which explains how the cultists joined with space pirates to take over the Earth and keep out the “Interplanetary Guard,” did not leave me optimistic about the quality of “Invisible One” by Neil R. Jones…

Invisible Men of Mars, by Edgar Rice Burroughs

Another reblog of a classic invisibility science fiction story, by a classic author! Hey, did I mention I have a book about the science of Invisibility out now?

skullsinthestars's avatarSkulls in the Stars

Nearing the end of my run of posts about invisibility in fiction! Be sure to look out for my book on the history of invisibility physics next year!

One thing that is truly amazing about invisibility in fiction is how much more prevalent it is than I first thought. So many famous authors have tackled stories about invisibility, from Jules Verne to Jack London to Ambrose Bierce to A.E. van Vogt. The idea of invisibility really has a power to it that has inspired many.

With that in mind, here’s another famous author’s story about invisibility, featuring one of his most famous creations! Today, we look at “Invisible Men of Mars,” by Edgar Rice Burroughs, which appeared in the October 1941 issue of Amazing Stories.

Edgar Rice Burroughs (1875-1950) probably needs no introduction, but if he does: he is the author of the Tarzan novels, which began in 1912…

“Invisibility” at Psyche Magazine!

The invisibility articles continue from me! I was really honored in recent months to be asked by the editors of Psyche Magazine, from Aeon Publishing, to write an article speculating on why the concept of invisibility has intrigued people so much over the centuries.

This is a topic that I didn’t discuss too much in my book, because I wanted to focus on the science of invisibility, so I was delighted to get the opportunity to wax philosophically about it. From the introduction to the piece:

Invisibility – the power not to be seen – has captured the fascination and fantasies of people for literally thousands of years. In the earliest imaginings, invisibility was a power bestowed by the gods. In the 1st or 2nd century CE, for example, a Greek author now known as Pseudo-Apollodorus wrote about Perseus’ quest to kill the gorgon Medusa, aided by the Cap of Hades: ‘Wearing it, he saw whom he pleased, but was not seen by others.’ With the aid of the cap, Perseus was able to claim the head of Medusa and escape unseen from her sisters Stheno and Euryale. Stories of invisibility have been told ever since. One of the most recent tales is the movie The Invisible Man (2020), a reimagining of H G Wells’s classic novel. In this film version, a man uses invisibility technology to stalk and control his ex-girlfriend.

This was a lot of fun to write, and a delight to work with the folks at Psyche! You can read the whole piece at this link. They don’t always allow comments on articles at Psyche, but are enabling them for my post, so if you have any questions or comments, feel free to leave a message over there!

Wrapping up the post with an image, just for sharing purposes!

Me, talking invisibility (again) with UNC Charlotte!

Another bit of invisibility book related news! My university did a short feature about my invisibility book and about invisibility physics in general; if you’re interested in taking a look, check out this link.

Thanks to Lynn Roberson for this fun interview, and for taking a picture of me that I don’t actually hate!

The Chameleon Man, by William P. McGivern

Here’s another reblog of a classic invisibility story! And another reminder that Invisibility: The History and Science of How Not to Be Seen is available!

skullsinthestars's avatarSkulls in the Stars

Getting closer to the end of my run of invisibility posts! Here’s one that’s a little different…

So when is something unable to be seen but not invisible? Well, the answer is handily demonstrated by William P. McGivern’s “The Chameleon Man,” which appeared in the January 1942 issue of Amazing Stories!

Let’s come back to this picture in a few moments. But here we’ve got a story about a different way of not being seen, and it’s worth talking about it!

Three Miles Down, by Harry Turtledove

It is curiously that I’ve never read any works by Harry Turtledove until now. He is an incredibly prolific author famed for his alternate histories, such as his Southern Victory series about the South winning the Civil War and his Worldwar series about aliens invading Earth during World War II.

Somehow I’ve just never quite gotten around to reading his work until he posted on Twitter about his most recent, Three Miles Down (2022).

This book, set in the most chaotic years of the 1970s (for Americans, at least), describes humankind’s first encounter with aliens — found lying deep under the ocean.

Land of the Shadow Dragons, by Eando Binder

Blog post about an invisibility story that is a sequel — the first one I’ve encountered! Still celebrating the release of my invisibility book.

skullsinthestars's avatarSkulls in the Stars

Just a reminder again that I’ll (hopefully) have a book out on the history and physics of invisibility next year, so keep an eye out!

Here we have a first in our discussion of invisibility in fiction — a sequel! “Land of the Shadow Dragons,” by Eando Binder, appeared in the May 1941 issue of Fantastic Adventures, and it is a direct sequel to Binder’s “The Invisible Robinhood.” It even merited a cover image:

It was weirdly thrilling to see the return of The Invisible Robinhood in print, even in this era of endless superhero movies and their sequels. This example, because it was much less common in that era, seems somehow more magical and precious to me. I’ll do some spoilers again, so read the story here first if you’re worried about that.
