Book Review: Existential Physics

This book by Sabine Hossenfelder is subtitled “A Scientist’s Guide to Life’s Biggest Questions.” It’s an interesting and refreshing approach to the seemingly impossible “facts” that others are offering about quantum mechanics. One of the great characteristics about this book is that Hossenfelder fearlessly identifies, and describes in clear detail, situations which science currently does not, and probably never will, prove or disprove. (Which is actually quite a big swath of the assertions you hear about the quantum world.)

Technical writers, of which science writing is a subset, don’t get a lot of love or praise. (Ahem.) But Hossenfelder deserves such, as this book is a gem of the genre. One of her very humane tactics is to include a chapter-concluding section called “The Brief Answer.” Instead of wading through all the details, skipping ahead to this summary makes the Big (but Less Interesting) Questions a lot more approachable. Because, frankly, some of them intrigued me more than others. For example, I devoured “Does the Past Still Exist,” but jumped to the brief answer for “Are You Just a Bag of Atoms.”

Here just a few of the notes I took:

  • Sociologist Steve Fuller claims that academics use incomprehensible terminology to keep insights sparse and thereby more valuable.
  • Science and religion have the same roots, and still today they tackle some of the same questions. (Indeed!)
  • Demarcating the current limits of science helps us recognize that some beliefs are not unscientific, but rather, ascientific.
  • “In the end, I hope you will find comfort in knowing that you do not need to silence rational thought to make space for hope, belief, and faith.”
  • Measurement in quantum mechanics destroys information for good. Other than that, and also black hole evaporation, information can’t be destroyed. Once someone dies, information about their unique ways, wisdom, and kindness becomes irretrievable and disperses quickly. But if you trust the math, the information is still there, somewhere, somehow, spread out over the universe but preserved forever. “It might sound crazy, but it’s compatible with all we currently know.”
  • In an interview with Tim Palmer, he and the author discuss how scientists who ridicule religion might alienate youngsters who would otherwise consider scientific pursuits. Science and belief are not always incompatible.
  • You can find many different diagnoses on death certificates, but those are just details. What really kills us is entropy increase.
  • Penrose’s conformed cyclic cosmology sounds a lot like Vishnu’s cycle of creating and destroying the universe. And Penrose’s theory is compatible with current scientific knowledge.
  • For the first time ever, I feel like I understand why the past, present, and future simultaneously exist, and there is no “now.”
  • Much of the supposed weirdness of quantum mechanics just comes from forcing it into everyday language. (See previous bullet point.)
  • Saying what’s beyond what we can observe is purely a matter of belief. If it cannot be observed, claiming it exists is ascientific, as is claiming it doesn’t exist. Don’t pretend that either of those is science. (Paging James Randi!)
  • Religion matters to people in a way that science does not. The two are “non-overlapping magisteria” and according to many people, science is too cold, technocratic, and unhumanly rational.

I bought my copy of the book at Barbara’s Bookstore, but you can also find it at the Amazon.



Book Review: A Hunter-Gatherer’s Guide to the 21st Century

My parents taught me to always “clean my plate” at meal times. That is, you should eat all that you’ve been given.

“Please clean your plate dear, the lord above can see ya. Don’t you know people are starving in Korea?” — Alice Cooper, Generation Landslide

Intentionally or not, for my whole life I’ve adopted that same attitude towards reading books. Oh, I have plenty of books in my library that I haven’t read (in re tsundoku), but once I begin reading one, I feel obligated to finish it.

That is, until this book. Written by “Heather Heyring and her partner Bret Weinstein, it is subtitled “Evolution and the Challenges of Modern Life.” That intriguing premise, and the cool cover (yes, I know) made it seem like something I’d enjoy. I was mistaken.

I won’t belabor the point, as based on other online reviews and the vitriol expressed towards the authors, I don’t need to overly justify my viewpoint. (Unfortunately, I learned about all this after I had purchased the book.) I’ll only add that while the authors might be smart biologists, when it comes to sociology, anthropology, and technology they are sadly lacking in sophistication.

But as is my practice, here are a few points that stood out for me:

  • “…culture exists in service to the genes. Long-standing cultural traits are as adaptive as eyes, leaves, or tentacles.”
  • The authors insist on using WEIRD as an acronym for societies which are “Western nations, with highly Educated populace, an Industrialized economic base, and are Rich and Democratic. That they labored so hard to make this derisive naming work will tell you a lot about their mindset.
  • “…the methods and language of science are imitated by institutions and systems not engaged in science, such that the resulting efforts are generally not scientific at all. Not only do we see words like theory and analysis wrapped around distinctly untheoretical (sic) and unanalyzed (and often unanalyzable) ideas, but — worse — we see the rise of a kind of fake numeracy, in which anything that can be counted is, and once you have the measurement, you tend to forgo all further analysis.”
  • don’t mistake identifying an effect for understanding an effect
  • REM sleep is the creative stage of rest

I stopped reading the book after one too many Jesus references, assertions about males being inherently dominant and females naturally submissive, and a statement that gender dysphoria is caused by endocrine disruptors in our environment. Skimming ahead, the latter half of the books seems filled with platitudes (“smile more”), glib advice (“sit around campfires with your family”), and, sadly, anti-vax bullshit.

Typically, when I’m finished with a book, I’ll donate it to a local Little Free Library so that others can enjoy it. This one is going straight into the trash.


Neighborhood sociopathology

Although I don’t have any medical training, I believe that I have accurately diagnosed a person who lives on my street as a sociopath. (And most likely, by implication, a Trump supporter.)

How did I reach this conclusion? Observation.

My kitchen window overlooks a busy urban street that is in high-demand for parking due to its proximity to popular storefronts and restaurants. When a parking space is vacated, it’s typically immediately taken up by another vehicle. Spaces are unmarked, so cars are parked bumper-to-bumper.

Except during the early hours of the morning. At that time, the stores are closed, and there are often open parking spaces with big gaps between them. And that is when I frequently see my neighbor strategically adjust where his two cars are parked.

He’ll rush out of his home and move both his vehicles so they are parked behind each other. This, you might be thinking, seems reasonable. But it’s where the pathology emerges.

He carefully places each car so that they consume the maximum amount of space. Positioning them just in front of a loading zone (so that nobody can park behind), and then leaving a several foot gap between his cars. I have even seen him pace out the space between his cars so that it’s large, but not so big as to be a usable spot.

When he’s done —and this process takes several minutes— his two cars are taking up enough space to park at least three, if not four, vehicles.

He’s precisely the type of person who should move to the suburbs. And here’s the kicker, he has a two-car garage that he doesn’t use. Definitely a sociopath.



Small-town Dead

This year, I’ve driven back-and-forth across much of the United States multiple times. Resulting in at least 6000 miles of travel, and several weeks of being on the road.

As a fan of Blue Highways, stopping in small-town America is always a highlight. (Although not always a respite when in Trump-y areas, such as Deadwood and all of Oklahoma.)

One consistent attribute of many small towns is what I’ve come to call “Dead Soldier Square.” It’s remarkable how many places have memorials to residents who have died in recent military service. Occasionally, it’s an old-school statue, but more often the memorial consists of photos of the dead on streetlight poles, or otherwise distributed along Main Street. Every so often, the placards are placed in the windows of empty storefronts, which makes them even more haunting and evocative by combining two forms of civic loss.

The photos of dead youth haunt your every step. The intention is probably to remind the living of their sacrifice, but I suspect the actual result is numbing and normalization.

It’s especially poignant knowing that for at least some of these young people, joining the military was the only viable means of escape from the town. And now, in death, the town is the only place where they are remembered.


Dealing with people who won’t stop talking

I wish I had read What I Learned About Interruption from Talk Radio when it was published in 2017. Back then, I was still spending several hours a day on conference calls, and sometimes struggling to get a word in edgewise.

Part of the issue is that telephone conference calls are not full-duplex, by design, so that when one caller is speaking the microphone of all the other callers are ignored. This makes it technically impossible to interrupt a speaker, except during pauses in their speech.

But the situation is greatly exacerbated when a speaker never takes a fucking breath.

Many of my colleagues were guilty of this. Oh, not on purpose, they just had the habit of drawing out their last word (or saying “ummmmm”) between sentences, or while they were thinking. This vocalization prevented others on the call from saying anything (which sometimes, was only me, as everyone else was in the same room). I wish I had a dollar for every time this happened during weekly staff meetings.

I’m hopeful that the pandemic — which put everyone in their own audio space on a conference call — helped teach people to be more polite and allow time for others to speak. But somehow, I doubt it.



Troubleshooting an IR remote control

The other day, my Sonos Playbase speaker stopped responding to the volume control buttons on my Apple TV Siri Remote Control. Here’s how I eventually resolved the problem.

The source of the issue proved difficult to diagnose because infrared is (of course) invisible light. I couldn’t determine if the Sonos was no longer seeing infrared signals, or if the remote was no longer sending them.

  • I quickly determined that I hadn’t added any new nearby electronics or LED light bulbs that might be interfering with IR signals. A lesson I learned from a confounding situation several years ago.
  • Using the Sonos app, I temporarily re-programmed the Playbase to respond to a TV remote it had not been previously trained on. When I was able to successfully do so, this established that the Playbase’s IR receiver was working.
  • The Apple TV remote was still able to control the Apple TV, but that uses an RF connection, not IR. (Sadly, the Playbase is IR-only.) But this confirmed that the remote’s battery wasn’t dead. I recharged it anyway, under the theory that perhaps the light emitter had grown too dim. This didn’t resolve the problem.
  • The next step was to reboot the remote. Yes, that’s a thing. After doing so, the problem was resolved. Yay!

If you have a remote control that suddenly and inexplicably stops working, I hope these steps will help you in solving the problem.


Nevada Political candidate signs

It’s election season in Nevada, and I was surprised to see how many candidate signs were placed in empty lots around Las Vegas. They were all lined up, like rows of corn plants in the Midwest.

But after seeing so many of these strange outcroppings, I began to notice a disturbing similarity. Many of the signs featured portraits of the candidates. (In fact, at first glance, they’re easy to mistake for Realtor advertisements.) However, of the signs that featured a photo, they were almost exclusively showing Caucasians. Mostly men, of course, but also white women.

Now, granted, Nevada is about 73% white, but I couldn’t escape the feeling that the message being sent was “Vote for me because I look like you.”



A solution for an outdoor speaker sound system

I needed to drive eight outdoor speakers, and clearly, I wanted remote control of their operation, and the ability to stream from Apple Music.

I could have utilized something like an Echo Link, or a Sonos Amp. But I rejected those options due to the cost (Sonos) and obnoxious assistive technology (Alexa).

What I ended up implementing is a bit of a Rube Goldberg machine, but it works well, and it did not break the bank. Here are the details:

  • A Belkin SoundForm Connect adapter acts as an AirPlay 2 receiver. This satisfies the requirement of streaming any music I desire either from my iPhone, HomePod, or Apple TV. The only downside is that the AUX output from the Belkin device is horrible, as many of the reviews on Amazon also note. Luckily, the optical output is OK, so I use that instead.
  • Because of the above-mentioned Belkin flaw, and the lack of optical support on inexpensive amplifiers (see below), a Digital Audio Converter is necessary. I settled on an inexpensive Amazon Basics DAC. It works well, and is USB powered, so I can run it from a power hub instead of using up another outlet in my network closet.
  • Audio amplification is provided by a Nubsound 100W mini-amp. It has built-in Bluetooth, which I turned off, as I prefer to use AirPlay. The amp itself is remarkably small — about the size of a Tarot deck. (You were expecting a less esoteric analogy from me? OK. About the size of two sticks of butter.)
  • Finally, I installed a Pyle Multi-zone Selector so that I can fine-tune the volume of each speaker pair. This also allows me to turn off speakers in unoccupied areas of the yard. (Because I’m a good neighbor.) A fancier solution would let me manage this remotely via my iPhone, but for under $100, this passive, no-power-required switch works well. It’s also small enough to fit, barely, on a shelf in the network closet.

Here’s a block diagram of how it’s all connected:

monodraw illlustration

The system works well, with a total cost that is hundreds less than a Sonos solution. (And cheaper than nosey Alexa, too.) The only downside is that I have to stream from a device to the amplifier. The Sonos can independently connect to Apple Music. But this is a limitation that I can take to the bank.

If you need me, I’ll be outside listening to Poolsuite FM.



Book Review: More Sneaky Feats

This book by Tom Ferrell and Lee Eisenberg is subtitled “The Art of Showing Off and 49 New Ways to Do It.” Published in 1976, the audience is clearly teenage boys, which I still consider myself to be.

There are several great little stunts described in this book, most of which are accompanied by Eisenberg’s charming illustrations.

I was already familiar with many of the stunts (given my lifelong obsession with the subject), but there were many new ones, too. Some of the ones that caught my eye include:

  • Tearing a phone book in half. I already know how to do this, but the method here is slightly different. This is undoubtably a vanishing skill, as finding a phone book to destroy is harder than ripping it.
  • Sticking a card to a wall. I wonder if this also works with beer mats.
  • A “Grandmother’s Necklace” style stunt using thread spools that ends with a dramatic, visual penetration.
  • A cat’s cradle style of buttonhole penetration.
  • A fun sight gag where a loose thread on your lapel or shirt turns out to be many yards of thread. (Spoiler alert: it’s unspooling from inside your pocket.)
  • A fantastic version of the Cartesian Devil, made with an eye-dropper.
  • A coffee can rolling boomerang that I simply must try soon.

This is the second volume in the Sneaky Feats series. The first volume apparently has 53 stunts, so I will keep my eye skinned for a copy of that. I found the present volume on Cherokee Street in St. Louis, inside a delightful used bookstore run by a gruff, pandemic-denying old man. If you want a copy (and you know that you do), I recommend the multi-volume compendium, which is currently available on the Amazon.
