Pirates of the Electromagnetic Waves

Fenton Wood’s Pirates of the Electromagnetic Waves is an amazing young adult techno-adventure reminiscent of Bertrand R. Brinley’s classic Mad Scientists Club (my review here). Set in an alternate universe nostalgically reminiscent of mid-century America, Wood tells the story of a boy and his young friends as they struggle to build and operate a radio station. I highly recommend this book, and I look forward to more Yankee Republic tales.

The Brave and Bold, Book 3 of the Hidden Truth Series – Readability

The Brave and the Bold is now uploaded and on Amazon’s servers. Clocking in at over 400 pages and more than 120,000 words, it’s the sequel Hidden Truth fans have been waiting for. That larger size drove an increase in the paperback price. The Hidden Truth and A Rambling Wreck are available in paperback for $14.99. The higher production cost for The Brave and the Bold persuaded me to set the purchase price to $15.99.

While Amazon’s servers were busy processing the file, I used Microsoft Word’s analytic features to check out the manuscript. You can access this feature through the menu path File> Options> Proofing> Show Readability Statistics. Then you have to suffer through a complete spelling and grammar scan of your document before you get rewarded with feedback at the end of the process.  Following are the results:

The Brave and the Bold tops out at just over 120k words, a respectable length for a novel. The Flesch Reading Ease follows from a formula that takes into account syllables per word and words per sentence. A score in the 60-70 range should be in the range for 13-15-year-old readers or about the 7th grade level. A lower score indicates more complicated words and longer sentences. You’ll all the sophisticated history and science you’ve come to expect from a “Hidden Truth” novel, delivered in simple, clear prose. I’ll have a release date for you soon.

For comparison, here was the result for A Rambling Wreck:

A Master Persuader at Work?

This incident reminds me of the time an investigator interviewed me as part of my roommate’s CIA clearance. Before we started, the investigator asked for directions to the bathroom. When he came back, his fly was unzipped, and without really thinking about it, I told him so. He zipped it up and we got on to the interview. To this day, I’ve never been certain whether it was accidental, or a deliberate ploy to put me at ease.

It would not surprise me in the least if Donald Trump did this deliberately so the media hounds would waste their time chasing after this particular squirrel, distract the media from barking on about the Kavanaugh nomination, and make Trump a more sympathetic figure.

Science Fiction Techno-Thriller, A Rambling Wreck, On Sale

Thought I’d share the news that my science fiction alternate history conspiracy thriller, A Rambling Wreck, will be on sale for $0.99 for the next couple of weeks.

Here’s an excerpt from John Walker’s recent review of A Rambling Wreck:

This series is a bit of Golden Age science fiction which somehow dropped into the early 21st century. It is a story of mystery, adventure, heroes, and villains, with interesting ideas and technical details which are plausible. The characters are interesting and grow as they are tested and learn from their experiences. And the story is related with a light touch, with plenty of smiles and laughs at the expense of those who richly deserve mockery and scorn. This book is superbly done and a worthy sequel to the first. I eagerly await the next, The Brave and the Bold.

If you’re a science fiction fan, consider participating in the Dragon Awards to honor the year’s best fiction. Declan Finn has a nice round-up of Dragon Award suggestions. A Rambling Wreck made Declan’s list as well as the Happy Frogs slate of recommendations.  There are many other fine works worth looking into as well.

Reviews for The Hidden Truth and a $0.99 Sale

The Hidden Truth: A Science Fiction Techno-Thriller by [Schantz, Hans G.]

This week, The Hidden Truth will be on sale for $0.99, so it’s a good time to take a look at some of the amazing reviews my science fiction techno-thriller continues to collect. Writing at Ratburger, John Walker had this to say:

This is a masterpiece of alternative history techno-thriller science fiction. It is rich in detail, full of interesting characters who interact and develop as the story unfolds, sound in the technical details which intersect with our world, insightful about science, technology, economics, government and the agenda of the “progressive” movement, and plausible in its presentation of the vast, ruthless, and shadowy conspiracy which lies under the surface of its world. And, above all, it is charming—these are characters you’d like to meet, even some of the villains because you want understand what motivates them.

At Wilder, Wealthy, and Wise, John Wilder writes:

…this isn’t like Atlas Shrugged with an 87 page speech that would have taken six days to deliver.  No.  The plot is tight, and the author doesn’t repeat himself.  The book is thrilling – especially the last third.

Joseph Moore, proprietor over at Yard Sale of the Mind reviewed The Hidden Truth a couple of months ago:

The story opens with some almost bucolic high school stuff, and establishes the main characters as believable denizens of a small country town. Then it adds electromagnetism and science history, mystery, conspiracy, and murder! Good stuff, good Sci Fi.  I had to laugh out loud at all the points in the story where a poor sensitivity reader’s head would gratifyingly explode. Schantz keeps a completely straight face about it all, which only makes it funnier. 

Pick up the eBook this week for the low price of only $0.99.

More Reviews for A Rambling Wreck

I just wanted to pass on a couple of wonderful reviews for A Rambling Wreck. From “Neovictorian” at the Sanity in the Diamond Age Blog:

It’s fun, it’s well written, it’s just plain good science fiction and it satisfies…. After you’ve read it, buy a copy (of both volumes) for your friends and children at school! Buy copies for younger kids, too. These books show how young people should conduct themselves with honor and perseverance, and not through preaching, but through example.

Here’s another from “Photog” at Orion’s Cold Fire:

I picked up this second volume of the series without having read the first because the premise caught my fancy.  The protagonist, Peter is a college freshman at Georgia Tech who is digging up information on a shadowy organization called the Civic Circle which seems like some kind of combination of the Illuminati and villains from a Bond movie.  They murdered his parents for getting in the way of an operation being carried out to hide the Civic Circle’s involvement in an assassination campaign.  This campaign was meant to prevent the leading minds in electromagnetic field theory from discovering a secret that would give its wielder enormous power.

Now imagine that plot line embedded in a story that includes a freshman pick-up artist, social justice warriors on campus, a Chinese demigod, a 17th century nuclear energy program and a freshman trying to keep his grade point average high enough to keep his scholarship money intact.

It’s sort of like what might happen if one of Heinlein’s juvenile heroes (say Kip from Have Spacesuit Will Travel) was thrust into the modern era and was forced to use “SJWs Always Lie” as his freshman orientation guide while battling the Black Hats.

Finally, from Bookhorde:

This is really such an original series of books that it’s hard to describe it properly. Like Da Vinci Code meets Harry Potter meets Cryptonomicon by way of Michael Crichton. The author really knows his science and tech AND can spin a fantastic tale. Highly recommended.

Thank you all for the great reviews!

I’ve been talking with some great folks about science fiction in general and my works in particular. Here’s a list of recent podcast appearances:

Dragon Award Nominations Close Tomorrow!

I regret being too busy to keep better track of the amazing quantity of fantastic science fiction from the last year. There’s a wealth of great material out there, though, and by selecting the works you found of particular value, you can help bring them to the attention of other readers. Without further ado, my nominations for the 2017 Dragon Awards:

  • Best SF Novel: Escaping Infinity, Richard Paolinelli – Excellent Twilight-Zone-like speculative science fiction. An honorable mention to Brian Niemeier’s The Secret Kings.
  • Best Fantasy Novel: A Sea of Skulls, Vox Day – Thoughtful, serious, fantasy is a rare commodity these days. The fact that it will annoy SJWs is a nice bonus.
  • Best YA: Rachel and the Many Splendored DreamlandL. Jagi Lamplighter Wright. Finally, someone does the “magical kids in a boarding academy facing existential threats” trope right. An honorable mention to John C. Wright’s Swan Knight Series.
  • Best Military SF: In Dread Silence (Warp Marine Corps Book 4), C.J. Carella (Carlos Martijena) – I love how C.J. Carella manages to integrate large scale galactic politics and small unit action in a compelling science fiction/Lovecraftian matrix. An honorable mention to Jon Del Arroz’s Star Realms: Rescue Run.
  • Best Alt History: Another Girl, Another Planet, Louis Antonelli – I’d have been tempted to nominate this for best SF overall, but it’s more likely to get the recognition it deserves in the alternate history list.
  • Best Apocalyptic Novel: A Place Outside the Wild, Dan Humphreys. Made me actually like zombie novels, and that’s quite an accomplishment.
  • Best Horror: Live and Let Bite. Declan Finn. What would the Dragon Awards be without Declan? It’s his turn. It’s always his turn. If I’d been more in the loop last year, I’d have nominated JP Mac’s Hallow Mass. Lovecraftian horror with a health dose of college campus politically-correct parody. Sadly, it’s not eligible this year.
  • Best Graphic Novel: Quantum Vibe, Scott Beiser/Big Head Press. Clever science-fiction action adventure with a libertarian bent. It’s free and updates every weekday. Check it out.

I’m not big into gaming and haven’t seen any movies that impressed me, so I will refer you to additional recommendations on those categories:

Check out their suggestions, and nominate your choices soon! Nominations close tomorrow!

Readability of A Rambling Wreck

Microsoft Word can analyze a document for readability. You can access this feature through the menu path File> Options> Proofing> Show Readability Statistics. Then you have to suffer through a complete spelling and grammar scan of your document before you get rewarded with feedback at the end of the process. I turned the analyzer loose on A Rambling Wreck, with the results to the right.

A Rambling Wreck tops out at just over 100k words, a respectable length for a novel. The Flesch Reading Ease follows from a formula that takes into account syllables per word and words per sentence. A score in the 60-70 range should be in the range for 13-15-year-old readers or about the 7th grade level. A lower score indicates more complicated words and longer setnences.

A Rambling Wreck requires some mindful reading – topics include history, physics, and the often obscure jargon of social justice activism. I’ve worked hard, however, to make the sometimes complicated material clear and accessible. Enjoy!


Reminded Me of Heinlein’s Have Space Suit Will Travel… 3

I’m taking a moment away from working on my draft of A Rambling Wreck to share with you the latest Amazon review of The Hidden Truth, courtesy of Steve D. Poling:

If Al Gore Had Won
Steve D. Poling

My first impression of The Hidden Truth was how much it reminded me of Heinlein’s Have Space Suit Will Travel. The protagonist is a kid coming to age through a process of solving technical problems. (As a Heinlein fan I consider this high praise.) I was also reminded of Jerry Pournelle and Larry Niven’s Co-dominium stories wherein technology is “managed” to maintain the status quo. (As a Pournelle and Niven fan…)

My second impression was a little troublesome. I am old enough to have lived through some history that I now see reflected, funhouse mirror style, in the mainstream media. What a younger me recognized as distortion and propaganda during the Cold War is now the grist of history documentaries–and no less distorted by the passage of time. Thus the central thesis of the book eerily mirrors my own recollection of days past.

I was particularly pleased to see Easter eggs placed throughout the text that made me think that the author reads all the right blogs. I laughed aloud when the protagonist loses a high school debate when his female opponent catches him unawares with a spirited denial of women’s suffrage!

If you believe the state should shepherd you through life from cradle to grave. You’ll hate this book. If you think that deplorable people ought not rule themselves, read something else. Conversely, if you think along more Jeffersonian lines, you’ll find this book a refreshing tonic. I certainly did.

Fans will be pleased to learn that the rough draft of A Rambling Wreck is now up to 85,000 words. The Hidden Truth clocked in at about 92,000 including a rather lengthy afterward. I have a few more scenes, currently in fragmentary state, to flesh out, then the second half will be sent to my alpha reader team while I start my editing and revisions of the first half. I believe I’m on track for a release at the end of June. I’ll begin posting more frequently as the release nears.

My Virginia Tech Talk: Energy Flow in Reactive Fields

Smith Chart of the near-field impedance for a magnetic dipole (top) and electric dipole (bottom).

I will visit Virginia Tech on Monday March 13th to give an EM seminar on “Energy Flow in Reactive Fields” at 1:00PM in the Whittemore 654 conference room.

  • Slides:

Abstract:  Energy Flow in Reactive Fields

Conventional wisdom treats radiation as a transverse kink in a field line and classifies the “near field” by where it appears: “near” a source. A closer examination of electromagnetic fundamentals reveals a different picture.

Electromagnetic waves propagate at the speed of light and comprise a balance of electric and magnetic energy. The free space impedance, 377 ohms, relates the electric and magnetic field intensities. When that balance is disturbed, there is an excess of electric or magnetic energy, and the energy slows down. In the limit where fields are purely static, the energy is at rest. By characterizing fields according to their impedance, we discover that “near,” or more properly, “reactive” fields exist all around us, and electromagnetic energy curves, bends, and behaves in counterintuitive ways.

These insights are crucial to understanding how radiation works – the transformation of bound electromagnetic energy into radiant energy. This talk considers radiation from an accelerating charge and from a dipole source to illustrate the fundamental point that the propagation of fields and the flow of energy behave differently, and each offers unique insights to how electromagnetic systems behave.

Finally this talk considers the application of reactive energy flow to understand not only the behavior of electrically-small antennas, but also the puzzle of two-slit interference in the context of quantum mechanics.

A Rambling Wreck Update

Leading a Cub Scout campfire program.

As you will have noticed, I’ve suspended blogging to work on other projects. I’ve spent my blogging time scouting instead. I will be a den leader and complete my “Wood Badge” ticket in the coming year. A wise friend, vigilante author Robert Bidinotto (whose vigilante thrillers you ought to check out), suggested I was better off working on my sequel than trying to promote my debut novel. I took his advice. It’s cost sales in the short run, but I’m hopeful expediting my sequel will make up for it in the long run.

I’ve been making good progress on A Rambling Wreck, sequel to The Hidden Truth. I’m about 50,000 words into my draft. I’m aiming for a release before LibertyCon June 30-July 2, but even if I miss that date, I’ll be done by the end of the summer. Expect a sample chapter soon. For now, I’ll reveal the first page of A Rambling Wreck:

Chapter 1: Whatever Happened to Angus McGuffin?

It was Angus McGuffin’s last day on earth, but he didn’t realize it until too late.


Between the salacious speculation why a missionary might frequent so seedy a neighborhood and the ample amounts of blood from the slaying, the Atlanta press was all over the case. “Missionary Slain,” the headline proclaimed. The details of Hitler’s latest aggression pushed the article below the front page fold of the next morning’s Atlanta Constitution. McGuffin almost ended up an unknown John Doe in a pauper’s grave. A fellow Presbyterian had recognized McGuffin’s picture in the evening’s Atlanta Journal from a church “Jubilee” held in 1913, and church leaders confirmed the identification. Was it just a random slaying? Who would want to kill a humble missionary back in the country after a quarter century abroad? Why was McGuffin living under an assumed name at a hotel? The reporter, Jack Sweeney, clearly knew there was more to it. His article had more questions and speculation than answers.


I already knew much more than appeared in Sweeney’s decades-old article. In the weeks before his brutal demise, McGuffin had completed a manuscript, “Suan Ming or the Art of Chinese Fortune Telling.” He sent a bound proof inscribed to his friend, “Bill,” at the Tolliver Technical Institute. The fire that “coincidentally” consumed the Magnolia Publishing Company the day McGuffin’s body was found probably accounted for the rest of the copies. The Civic Circle’s Technology Containment Team, or whatever they were calling it way back then, must soon have secured any remaining copies or notes.


All but one.


Forgotten over sixty years in my hometown up in the mountains of eastern Tennessee, that last remaining copy gathered dust on a shelf in the Tolliver Library until that library, too, burned to the ground last year. Only we got there first, and preserved McGuffin’s legacy. Now, I was trying to piece together the puzzle of whatever happened to Angus McGuffin. Because, the people who killed Angus McGuffin also killed my parents.

Pete and Amit are off to Georgia Tech to continue their research into the real meaning of the hidden truth, and to prepare themselves for the coming battle. Only, their enemies are busy, also, with a scheme to corrupt and subvert the school. Our heroes will have to find a way to enlist the help of George P. Burdell, himself, to save the school, thwart an ancient secret society, unlock the secret meaning of the hidden truth, and somehow find the time to study for their final exams. With new enemies, new allies, new challenges, and new mysteries to unravel, fans of The Hidden Truth will not be disappointed.

The Hidden Truth “Updates the Classical Arguments of Heinlein and Rand”

hiddentruth800The Hidden Truth  has earned some great reviews. Here’s one of the latest:

on October 16, 2016

What an enjoyable read! Hans’s story pulls you in and won’t let you go until the end. I was already familiar with his expertise in electromagnetics, which is sprinkled throughout the book. But I had no idea he knew so much about computer hacking and the art of picking up girls!

All fun aside, this book has a more serious purpose – it is an impassioned plea in support of libertarian principles. In this respect, Hans updates the classical arguments of Heinlein and Rand for a more modern and younger audience. Maybe this time it will work – one can only hope!

Hans’s technical books have already made him famous in electromagnetics. It seems likely that his fiction will extend his notoriety outside that narrow area. Bravo for this first effort! I look forward to many more.

The Hidden Truth is available on Amazon.

Welcome Home Apollo 12 1

In 2002, astronomers noted that the Earth acquired a new “moon,” dubbed J002E3. Such orbits are unstable in the long run, due to the likelihood of interactions with the Earth and Moon perturbing the orbit of such a small object. As observational data continued to accumulate, it became obvious that this object had some peculiar characteristics. It’s orbit was strongly perturbed by the pressure of solar radiation, indicating the object was not very dense.


The motion of J002E3, showing how the object was captured into its chaotic orbit around the Earth by passing near the L1 point, looping around the Earth for 6 orbits, and then leaving Earth’s orbit. The Sun is to the left in these animations (NASA/Paul Chodas & Ron Baalke, 2002, Public Domain; Courtesy Wikimedia)

As the object continued an elaborate dance of a half dozen orbits around the Earth and Moon, observations indicated light reflected by the object was consistent with the spectral characteristics of white paint, black paint, and aluminum.


S-IVB stage of Apollo 17, identical to that from Apollo 12 (NASA, Public Domain, 1972, courtesy Wikimedia).

Although the orbital motions and interactions with solar radiation make the object’s orbit too chaotic to trace with a high degree of certainty, backtracking its orbit led to the conclusion that it had last been in the vicinity of the Earth in 1971. Scientists believe the object is the missing third stage of Apollo 12.

After a half dozen orbits of the Earth, a close pass with the moon perturbed the object back into a heliocentric orbit around the sun. Scientists estimate another close approach sometime in the 2040’s.

Video Lecture: Energy Flow in Reactive FIelds

A couple of weeks ago, I traveled to the UK to attend the Logistics Research Network Conference and present some talks. One, presented at the James Clerk Maxwell Institute and Newcastle University, explained my ideas on energy in reactive fields. The kind folks at Newcastle University have posted a video of my talk.


Dr. Hans G. Schantz presenting “Energy Flow in Reactive Fields” at Newcastle University on 6 September, 2016 (courtesy Fei Xia).

My talk proposes a novel definition of near or reactive fields by reference to the electromagnetic Lagrangian and reviews basic concepts including energy velocity, energy flow, and impedance from a reactive perspective. Schelkunoff’s 1-D transmission line concept serves as a simple conceptual framework within which to understand the behavior and motion of energy in the context of opens, shorts, and other basic examples. Application of these concepts to the dipole fields reveal fundamental properties of small antennas including quality factor and gain limits. Finally, these ideas have practical applications in understanding the different behavior of electric and magnetic antennas, in employing near-field wireless links, and elsewhere in physics.

The Electromagnetic History of Newcastle


The “Lit&Phil,” Newcastle-Upon-Tyne, where Oliver Heaviside began his study of electricity and magnetism (photo by ÆtherCzar).

Newcastle-Upon-Tyne holds a key place in electromagnetic history. Founded in 1793, the “Lit & Phil,” or Literary and Philosophical Society of Newcastle, is the largest independent library in the UK outside London, housing over 160,000 books. It was at the Lit & Phil that a humble telegrapher, Oliver Heaviside, first studied Maxwell’s theory of electricity and magnetism. Heaviside went on to “make patent what was latent” in Maxwell’s sometimes obscure theory, reducing it to the four “Maxwell’s Equations” employed by physicists and engineers to this day.

Heaviside’s own works – freshly rebound – grace the shelves there, embedded among some of the very texts the young student of electricity and magnetism would have encountered well over a century ago.


Newcastle’s electromagnetic claim to fame does not end at Oliver Heaviside, however. Joseph Wilson Swan demonstrated his light bulb in 1878. A few months later, on February 3, 1879, he demonstrated his bulb in a lecture at the Lit & Phil. Swan’s lightbulb is on display at the Discovery Museum.
