How to Write an Ending No One Can Guess

writingThere are two ways to do it best. One is to start with an ending and work backward. I did this in Postmarked for Death, which began as a nightmare I had, involving an abandoned missile silo taken over by a madman. Not the usual scenario, either: there was no Hollywood missile, as in the movie “Twilight’s Last Gleaming.” It was just two guys in the dark, each with a gun, listening intently for movement in the utter silence. The advantages to this method is that once you know where you’re going, it’s a journey of discovery to get there. Why are these two guys there? How did they get there—what led to it? Once you know who they are, and have established them vividly, the novel will write itself. Better if each is not a walking cliché (walking dead man) but a fallible, real person with both good and bad in them. They have made wrong decisions in the past, but redemption comes in making the right decision in the end. The second method is not knowing the ending. Again, you have the main character fleshed out. And a firm idea of what his or her dilemma is. In the case of The Methuselah Gene, I knew it was going to be a thriller about Big Pharma: how pharmaceutical drugs are tested and produced, combined with how the science of longevity may produce a drug in the near future to extend life by a decade or more. (Science validated recently in the Ron Howard series Breakthroughs.) With the main character (a bachelor researcher tortured by anxiety) fleshed out, it became a matter of doing research, and interviewing a few scientists in the field of genetic engineering so that the plot idea would be plausible. After that? A blank sheet of paper. No idea what would happen to this character, who he would meet, and how the plot idea would evolve. I simply put him into a situation, and listened to what he might say. As one of my fav actors, James Garner, once put it in his biography: “I don’t act, I react. Give me a reactor over an actor every time. As soon as you look like you’re acting, you’re dead. You’re just chewing the scenery.”  That’s the way I did it. I put him in motion, and told it from his point of view. He surprised me. That way, there is no way the reader won’t be surprised too. Just let go.

Telescope Science

telescopes

A universal trait of engineers is their curiosity with how things work, and nothing arouses more curiosity than the laws that govern the universe itself. Such laws seem to break down at the extremes of size, both on a small scale, in particle accelerators, for example, and on the vast scale, as detected by telescopes. In each case, tools designed by engineers now probe these mysteries, discovering the surprising nature of matter and energy.
—A shining example is the new Large Binocular Telescope (LBT) atop Mt. Graham in southeastern Arizona, which enables scientists to study objects like the supermassive black holes at the centers of galaxies. For a personal tour of this revolutionary telescope housed at Mount Graham International Observatory near Safford, I joined Dr. Richard Green, LBT’s director, on a clear, sunny day for the 125-mile drive northeast of Tucson to the remote mountain.
—At 10,700 feet, Mt. Graham rises from the desert like a sky island of unexpected beauty. In contrast to the cactus below, 200-hundred-year-old Douglas fir trees grace the upper reaches of the mountain. Yet by following a final twisting dirt road to the summit, past several security checkpoints, a more unexpected marvel soon appears–the LBT observatory building itself. This $120 million dollar facility is home to the most powerful optical telescope in the world–a 600 metric ton all-steel mount encapsulating two massive 8.4-meter mirrors, each the largest of their kind yet deployed. Indeed, once the mirrors are phased together, this visionary binocular will function as if it was a Cyclops with a single mirror 11.8 meters wide–impossible to produce with today’s technology–and with an angular resolution of 22.8 meters. With a honeycomb design, the mirrors sit on a single mount and are more rigid and lighter weight than conventional solid-glass mirrors. Together they collect more light than any existing single telescope.
—While the telescope’s size is revolutionary, so is its precision, accuracy, and sensitivity. During my visit, I witnessed the lowering of the twin mirrors for scheduled attachment of a red-sensitive camera to a deployment arm and was told that the moveable mount, despite weighing 600 tons, is steered easily under the power of a one-horsepower electric motor. “The structure actually floats on an oil pressure pad, like a rocking chair, thanks to 12,000 PSI,” Dr. Green tells me, “so if you had to move it by hand, you probably could.”
—Added Dr. John Little, LBT’s lead site engineer, “The ride from vertical to horizontal is twelve minutes, or one minute, depending on speed selection of the analog drive.” When I asked if there was any smallest degree to which the telescope could be angled, Little replied, “Not really. With digital feeding, the mirrors will be able to be positioned to resolve one thousandth of an arc-second, or roughly a BB at 32 and a half miles.” Luckily, testing for degradation of positioning at various elevations has revealed almost no deviation. And though counterbalancing is still a problem, considering the heavy instrumentation that will be swung in and out of position, there is a solution coming in the form of a newly designed dynamic fluid system that will pump a water and antifreeze mixture to various tanks within the structure to compensate. “For now we’re using physical weights,” says Little, pointing to what looked like stacked barbell rounds at the ends of the matrix.

The LBT Corporation was established in 1992 to undertake construction and operation of the LBT, which evolved from an international partnership of over 15 institutions from around the world. The University of Arizona (UA), which also represents Arizona State University and Northern Arizona University on the project, holds a quarter partnership in the LBT. The Instituto Nazionale di Astrofisica, representing observatories in Florence, Bologna, Rome, Padua, Milan and elsewhere in Italy, is also quarter partner in the project. Ohio State University and the Research Corporation each holds a one-eighth share, with Research Corporation providing participation for the University of Notre Dame, the University of Minnesota, and the University of Virginia. Germany is the fourth quarter partner, with contributing science institutions in Heidelberg, Potsdam, Munich, and Bonn. The Research Corporation promotes the advancement of science in the United States and ensured that funding was available at critical stages of the LBT’s development.
—Work on the LBT began with construction of the one-of-a-kind telescope building in 1996, led by UA. The structure consists of 16 stories, and the top ten floors rotate.
As to the massive 8.4-meter dual mirrors themselves, they were spun cast in Tucson, at the UA’s Steward Observatory Mirror Lab. In the state-of-the-art facility, housed in the campus football stadium, a huge furnace heated the 20 tons of glass, gently spinning it into a parabolic shape at 2130 F before it was cooled and polished to an accuracy of about 3000 times thinner than a human hair.
—UA engineer Warren Davison developed the telescope’s innovative compact, stiff design in collaboration with other engineers in the United States and Italy. The major mechanical parts for the LBT were fabricated, pre-assembled, and tested at the Ansaldo/Camozzi steel works in Milan, one of Italy’s oldest steel manufacturers. Then the telescope was disassembled and shipped by freighter to Houston, Texas, and overland to Safford. The mirror cell continued to the Mirror Lab, where a team integrated the mirror support system and mirrors into the cell before a heavy equipment moving company hauled the assembly up the mountain. The LBT saw first light in 2005, and the LBT Observatory currently has a staff of approximately 50 scientists, engineers and technicians.
—What type of technical background does it take to work on a telescope like the LBT? Green studied quasars and black holes during his graduate student days, back when he was a member of the science team that built the Hubble Space Telescope instrument that surveyed nearby giant galaxies. He served as director of the nearby Kitt Peak National Observatory before coming to LBT a year ago to handle public relations and scheduling of telescope time. A charming and self deprecating man with wide interests, he engaged me in conversation about many topics, from the mostly private funding of the project and its limited access to scientists (outside the consortium of universities involved), to the latest theories about dark energy, the Big Bang, and even the movie Blade Runner. But he is truly an astronomer first.
—Other career paths to LBT played out differently. Dr. John Little, who worked in medical electronics, industrial controls, and military electronics before coming to the project, wasn’t very familiar with astronomy at all, except as an amateur. “I went to Cal State at Sacramento for a degree in electrical engineering and remote sensing, then to the University of New Mexico for a masters in electromagnetics before some work at Utah State in optics,” he told me, his steady blue eyes focused on days past. “So what’s great about working here is that all these disciplines are involved. On top of that, it’s exciting to see the data come in. When we get our adaptive optics running–taking the ‘twinkle’ out of the stars, so to speak–the clarity will be ten times that of Hubble. And so when we’re pulling in images for the first time here, we’ll be seeing them come right off the camera, and that’ll be a thrill.”
—Also working in controlling the axis to position the telescope accurately, but in software rather than hardware, is Chief Software Engineer Norm Cushing, who told me, “At one point in my career I was working on HDTV set boxes, digital recorders and the like, and I realized right away that just wasn’t as intellectually fulfilling. There was something missing. Call it awe. That’s the missing ingredient which LBT supplies.” Immediately prior to his arrival at LBT, Cushing developed software related to satellite tracking. “That background in image processing married well to what happens here, but it’s been a phenomenal learning experience, too. When I arrived, I learned how little I really knew, especially about astronomy. Some know a lot, like Joar Brynnel, chief hardware engineer, who told me he needs his people to understand the concepts to fix problems in a reasonable time.”
—Members of Cushing’s group write low-level embedded software in assembly language and higher level software modules running in Linux that talk to each other through reflective memory. “Algorithms for right ascension and declination are created to actually steer the telescope and make it move to position and track objects,” Cushing explains. “Lower level commands control the motion of the building to follow the telescope.” And is this software new and as exciting as being an astronomer? “All of it is new, written from scratch for this system,” he replies, then adds, “When I was a boy, running around in my PJs, my sister would call me whenever Carl Sagan was on TV. I’d run out, and it was all fascinating. So it’s been a dream come true for me, too.”
Astronomers as Engineers
Not that engineers can’t be astronomers themselves, or vice versa. Take Roberto Ragazzoni from the Instituto Nazionale di Astrofisica in Italy, one of the member institutions of LBT. “I would say one in five astronomers also make instrumentation for radio or optical astronomy,” he tells me. As an astronomer, Ragazzoni once studied planetary nebula in an observatory in Chile. He has extensive knowledge of astrophysics, but now he mostly designs and tests the instrumentation used on large telescopes, and he labels the scale of most of the scientific instruments used on LBT as revolutionary.
—“Two interferometers are being made for this telescope,” Roberto tells me over a plate of spaghetti in the observatory’s kitchen. “One at the U of A, and the other in Germany and Italy.” An interferometer combines the signals of two separate telescopes (or mirrors) almost as if they were coming from separate portions of a telescope (or mirror) as big as the distance between the two telescopes. It works on the principle that two waves that coincide with the same phase will add to each other while two waves that have opposite phases will cancel each other out, assuming both have the same amplitude. The instrument provides unprecedented imaging capability at infrared wavelengths and in its “nulling” mode reduces the glare from stars, thereby permitting the detection of orbiting planets or dust disks, which would otherwise be overwhelmed by the star light. “What’s new is the scale to which this technology is being applied, and also, instead of using a laser for alignment, we use a wider field of view, with the light from several faint stars, which are then combined.”
—With such technology, astronomers can use the LBT to find and image the first Earth-sized extra-solar planets, employing the telescope’s astonishing light gathering power accompanied by an array of cameras, spectrometers, and interferometers –some the size of compact cars and weighing a ton. Or it can map the neighborhood of the inner Milky Way, where a monster black hole flings stray stars off on wild eccentric orbits as if they were mere marbles in a child’s game.
—After Roberto ate his plate of spaghetti with garlic and olive oil, I asked him if astronomers like him were not actually providing a microscope for laymen to see themselves as smaller and smaller as the universe they saw got bigger and bigger in their giant lenses. He laughed. Perhaps I reminded him of the children he once talked to about his work in adaptive optics, when one asked how he “made a star, which was so big, look so small.”

Flat Earth & the Role of Satire

AGTSATIRE: humor that uses exaggeration, wit, irony, and/or sarcasm to expose and discredit vice or folly. Humor with a point. It is a difficult medium to pull off well, and “whistleblowers” are frowned upon in our culture (except in sports, with real whistles), but some of the best literary figures in history employed satire as a means to keep the nation free of tyranny and repression. Voltaire, P.G. Wodehouse, Oscar Wilde, O. Henry, Lewis Carroll, George Orwell, Will Rogers, Charles Dickens, Ambrose Bierce, Kurt Vonnegut, Ray Bradbury, Joseph Heller, Gore Vidal, Woody Allen, Chuck Palahniuk, Bret Easton Ellis, the list goes on. Then there’s The Simpsons, Futurama, South Park, The Family Guy and other shows. Robin Williams said, “People say satire is dead. No, it’s alive and living in the White House.” (He was referring to Bush.) In this spirit I dedicated an ebook to Ray Bradbury, who answered every letter I wrote him with kindness and insight:  TrumpWorld: an Amazon alternate universe fantasy ebook in which Trump is homeless and living under a bridge in a cardboard box. (“Will Work For Votes.”) Of course Hillary is involved in scandals too, her “team” having dissed Sanders, and with Bill Clinton having endorsed tyrants in the past, along with signing the Glass Steagall repeal (written by the GOP), which let Wall Street do its shady deals and led to the collapse of 2008. These two are the only choices you have, and you have to decide! I prefer the Coffee Party (look it up.)  The World’s First Trillionaire  is satire about a dweeb named Howard Rosen, who explains to the Rolling Stone how he became Super Duper Rich (SDR), with extended lifespan, a yacht that is also a sub (with nuclear torpedoes), and why his mansions and luxury cars don’t show up on Google Maps. (Also, why the NSA fears him, although he prefers to walk or take a cab. LOL.) Regarding the Flat Earth, there are literally hundreds of videos on Youtube that support it, and Trump. They disbelieve anything science says about anything, not just global warming. NASA lies about everything, they say, and yet some use NASA photos of the moon in other videos showing strange UFOs there. (You can’t have it both ways.) I had a cover article in Sky & Telescope (read part of it here), and spent four hours driving in a van to the Mt. Graham telescope near Tucson with the director. Just him and me, discussing his work on the Hubble team, physics, the scientific method, plus his directing the Kitt Peak National Observatory. I’ve also written about Kitt Peak for other magazines, and conducted research at the library, besides reading dozens of books on the subject. My novel The Miraculous Plot of Leiter & Lott uses optical science and physics in its plot, and is set in Tucson and Dubai, which Neil deGrasse Tyson used as just one example to prove the curvature of the Earth from atop the Burj Khalifa (where you can see it.) Yet many Youtubers (who don’t read books and get their McNews there) believe bling-a-lings who cherry pick their “evidence” and don’t realize that real science is self correcting. Or the “History” Channel.  Scientists all want to win a Nobel Prize (instant fame, prestige and wealth), and they don’t do that by shouting, they do it by proving. We refuse to see the world except as a competition between teams, races, religions…our gut reaction is to take sides, throwing bombs (or, symbolically, footballs.) We memorize things by rote in school, look at Tweets and think we know far more than we do, but don’t learn to think. So we are impervious to changing our opinions (given to us by social media giants who track us and feed back to us only what we already like and believe, hiding everything else) even when presented with new evidence. The Bible says the Earth is flat? Please. Time to wake up and smell the dark roast.
