Last week Douglas Wilson wrote an excellent blog post mentioning Calvinball, a game invented by Calvin and Hobbes author Bill Watterson. While Wilson’s main point is the need for Christians to maintain consistent definitions in the cultural battles that rage around us, he got me thinking about what a brilliant metaphor Calvinball is for the aggressive relativism of our day.
Bill Watterson, easily the best comic strip writer and artist since Walt Kelly, was an extremely gentle satirist. While he would occasionally poke fun at academic double-speak, the shallowness of mass media, or modern artists, I’m sure that Calvinball was not meant to represent the philosophical system behind post-modern thought. It’s merely the spontaneous creation of an extremely self-centered six-year-old trying to have everything his own way. On second thought, how could the game not exactly reflect the liberal ideal of total moral relativism?
Calvinball is the perfect representation of a game with no rules, no standards, and nothing to stop you from changing absolutely everything about the game all of the time. As Doug Wilson points out, there’s no point in playing a game, or having a conversation, when the definitions are totally fluid and even the goal of the argument is in flux. For one thing, it becomes impossible keep track of the score.
When I lived in New Zealand, I learned a little bit about the sheep business. It’s handled differently there than in the rest of the world, particularly on the South Island, where sheep farmers run exceptionally large flocks. The typical practice is to send the sheep out to forage for themselves, up into the hills and mountains, and there isn’t much messing around with fences and paddocks. At shearing time, the sheep are mustered together back at the station, usually by part-time hands using dogs and ATVs. After the sheep are sheared and dipped, they get sent back into the wilderness to continue fending for themselves.
New Zealand’s average flock size is 3000 ewes, with an estimated 7000 sheep per shepherd ratio. This farming method really only works because this unique island nation has a very mild climate, a great abundance of forage, and a complete lack of predators. The rest of the world is generally less forgiving to wandering sheep.
In the Bible, we see Jacob and Moses leading their flocks far, far afield in search of food and water. David has to defend his sheep from lions and bears. Psalm 23 describes a shepherd as being constantly close to his flock, providing all of their sustenance, protection, and comfort. He goes into the wilderness with his flock. He experiences all of the same discomforts and dangers that they do, no matter if it is rough terrain, bad weather, or deadly beasts.
While there are many American megachurches that to follow the Kiwi model – sending thousands of sheep wandering into the wilderness to look after themselves, only sporadically rounding them up for fleecing and dipping – the New Testament makes it clear that elders and deacons are meant to imitate the shepherds of the Old Testament. 1 Peter 5, after four chapters of exhorting us to put off unrighteousness and put on more holy behavior, even in trials, says this:
Last week Isaac showed you our own homemade contraption using the Toddy felt filters, mason jars, plastic mason jar caps. Now that I’ve been testing it for a couple of week, I’ve decided what I like best. Here are all the things that I have tested so far:
Toddy Cold Brewer
The system that inspired our experiment was a gadget my sister owns, called the Toddy system. A simple plastic brewing container rests over the top of a carafe or mason jar. You layer coffee and water in the top portion, and let it sit 12-24 hours. Then you remove the cork plug at the base of the plastic container, and it slowly drips through a small felt filter into the mason jar below. Some aficionados claim it produces a clearer, less cloudy brew, since you aren’t stirring or disturbing the grounds as you prepare to filter it. You end up with approximately 5-6 cups of cold coffee at the end, so it doesn’t have a huge capacity. It’s one more gadget that I don’t have room for in my kitchen right now, but I love the simplicity. Also, at $35 for the initial investment, and then $2.50 for felt replacement filters, it’s not cheap.
Isaac’s Hourglass Invention
While this thing was fun to experiment with, it’s a bit of trouble to assemble. Which way does that straw go in? Which side do I screw to which jar? Every time I put it together I felt like it was an IQ puzzle meant to test my spacial awareness. And since it uses the Toddy filters, you still have the downside of needing to occasionally buy new ones. The upside is that I can use the mason jars I already own, the half-gallon jars make enough for almost a whole week for the two of us, and the only cost is teo wide mouth plastic caps, one narrow mouth plastic cap, a little caulk, glue, and a long straw. It works perfectly, but it’s more parts to disassemble, wash, and reassemble.
A couple of weeks ago, celebrity astrophysicist, podcaster, and TV host Neil deGrasse Tyson proposed an entire system of global government in a single tweet: “Earth needs a virtual country: #Rationalia, with a one-line Constitution: All policy shall be based on the weight of evidence.” This concept is admirable for its brevity… but not much else. While this particular hashtag hasn’t exactly gone viral (less than 400 posts so far), it has had a lot of reach (almost 800,000 viewers). It’s also generated a lot of discussion elsewhere, and US News, Slate, and Popular Science have all published op-eds attacking this popular scientist’s idea, and from several different angles.
Popular Science pointed out that science is merely an evolving tool. Slate’s Jeffrey Guhin lammed scientism, claiming that creationists are as scientifically adept as their evolutionist counterparts, and yet despite all this science they are still wrong. Robert F. Graboyes wrote for US News about several blood-soaked times that this “rational society” idea has been tried throughout history, and it’s a good read. We should never forget the “Temples of Reason” that presided over the French Reign of Terror, the sheer bodycount of “scientific socialism,” or the creeping horror of eugenic engineering.
But none of these articles criticizing the idea of science as a holy and pure ideal are complete. It is obvious that definitions of science change, and that imperfect human scientists will have flaws and foibles. It is even obvious that facts are not self-evident and statistics do not speak for themselves. Facts do not judge; they are judged. All evidence must be interpreted. All interpreters will have a lens through which they view the raw data; a worldview that shapes their conclusions.
In case our readers hadn’t noticed yet, it is now completely summertime (here in the Northern Hemisphere, anyway). Our air conditioning is running for a lot of the day, James is a little less excited about playing outside right after his morning nap, and Heidi and I are pretty much only drinking coffee that is full of ice.
We aren’t really coffee aficionados, but do we usually grind our own coffee and brew it in a French press like some coffee snobs swear by. Now that it’s warmer, we’ve begun cold-brewing our coffee, and despite the fact that cold-brewed coffee has a different flavor and possibly less caffeine, we like it. For those that haven’t tried the now popular practice, cold-brewing involves steeping ground coffee in much cooler water for a much longer time. We use room temperature water and let it steep for about 24 hours.
It’s just as easy to make, as long as you prepare the coffee far enough ahead of time that it will be ready when you want to drink it. We’ve been making tomorrow’s coffee right after pouring today’s coffee that we started brewing in our French press yesterday. However, the French press doesn’t hold too much, and it doesn’t filter out quite all the grounds. As usual, I thought there could be a better way.
The L16 camera is the latest consumer-accessible version of a scientific imaging technique called computational photography. Now to some extent, all digital photography is computational photography. For example, all CMOS sensors that use a Bayer color filter require computational models to interpolate what the color values are in each of the pixels that they capture.
But what the L16 does is much more complicated. Instead of a recording the photons collected and focused by a single lens, it has 16 sensors and 16 lenses. There are some significant advantages to this. First of all, the total surface area of the sensor array can be increased by adding more small lenses, instead of increasing the size and weight of a single big lens.
This is not a new idea, in fact this is exactly how an insect’s compound eye works: many tiny lenses capture many images that the insect’s brain instantly comprehends as one image. The L16 does this a bit slower, taking the data from 16 different sensors and 16 different lenses, and assembling it into a single image that should have greater detail, less noise, and some additional data that a single sensor could not have captured on its own.
It’s now been one week since the historic vote for British Independence, and the Brexit celebration and the Brexit panic have been colliding ever since. The Pound has yet to recover from that panic, but the $3 trillion dollars that journalist claimed had been evaporated, vaporized, or wiped out of the global markets has mostly come back. Amazing, how wealth can vanish into thin air, and then just as quickly reappear, right out of thin air, just like that.
Anyhow, in the last week, Britain’s angry “Remainers” have had time to publicly demand that their politicians not listen to public demands, and the EU’s angrier officials have been constantly breathing out threats and demands against the UK. In addition to possible embargoes and boycotts, the EU is how moving to punish British voters by banning the appliances that make their beloved tea and toast. There is even talk of war.
Prime Minister David Cameron, for example, has fretted that without the EU’s protection and advice, the UK and other European powers might be plunged into foolish and costly foreign wars (like the recent Gulf wars, perhaps?). Some analysts have gone further, suggesting that the only thing preventing bloody wars between European nations has been the benevolent oversight of the European Union. Without its British backing, the collapse of the EU is possible, which these fearmongers say would immediately spark a new series of European Wars, possibly a new World War.
Despite the underwhelming response to Google Glass and the overwhelming hype surrounding various VR headsets, it’s pretty safe to say that the future of head-mounted displays is very bright. And while most folks are excited about the gaming potential of immersive displays like the Oculus Rift, I think that transparent Augmented Reality displays like Microsoft’s HoloLens will get more overall use, simply because they can be used for more things.
However, all of these displays seem too expensive, too big, too delicate, and too early in development to have any apps for your personal job. I’d love to have a little screen sitting just under my right eye showing me my emails, camera viewfinder, CNC machine terminal, caliper display, and so on, but that technology is a little far off, and who knows how useful it would actually be in day-to-day practice? I think it’s worth building something that’s a little simpler to implement for the sake of experimentation.
I think that someone should build a basic Bluetooth headset with a little microphone boom which has a multi-color LED on the end. I don’t think it would need to be much longer than two inches to get that flashing LED into the wearer’s peripheral vision (try this yourself with a tiny LED and let me know what you find), and little plastic prism would direct the light toward the eye and away from other folks.
In many ways, Britain’s national history began when it left the Roman Empire. Throughout its many centuries, Britons have defined themselves as freedom-loving, independent people, very often resisting larger multi-national organizations or top-heavy systems of government. To choose just a few examples, King Alfred led his countrymen out of an encroaching Viking nation, Henry VIII removed his country from an increasingly tyrannical Roman Catholic Empire, William Wilberforce extracted Britain from the global slave trade, and Winston Churchill rallied his people to repel the ever-increasing Third Reich and then to beat it back from the lands it had swallowed up.
Despite this rich tapestry of freedom, I was a little surprised to watch as Britain voted itself out of the European Union yesterday. I’d seen so much fear and panic in the media, and so many English celebrities moping about how much costlier their vacations would be if the tiny UK left the utopic pantheon of European powers, that I wasn’t really sure if modern Britons would follow their ancestral heritage. Fortunately, they did… just barely.
As we watched the results being reported last night, the financial markets went wild. When it became apparent that little old Britain was probably going to paddle off alone into the Atlantic after all, the Pound dropped like a rock as investors swapped them out for safer currencies, like American Dollars, Yen, or gold. But despite deep pessimism about the UK’s future without the all-powerful EU, nobody was buying up Euros.
We had an unexpected visitor last night. Well, I should say that it was not expected by Heidi. Heidi is from Colorado, so she is often surprised to find bugs in our house. I have been living in Tennessee for long enough that I am more surprised when there are not bugs in our house.
We were on our way to bed after putting James down for the night, and found a large beetle flying around in our room. It was a pretty large beetle to be airborne, and demonstrated very accurate navigation, even in the dark. When it landed on the floor I noticed something very strange about it – it seemed to carrying a colony of tiny spiders that were swarming all over its head and body.
Because I am not an entomologist, I was just slightly grossed out. Also, when I pointed a flashlight at the beetle it flipped itself onto its back, and I noticed that its abdomen was emitting what real entomologists call “a foul-smelling fluid.” I quickly used a piece of paper to flick the dying beetle out our bedroom door, assuming that he had been unfortunate enough to be killed by a bloodthirsty mob of baby spiders… but that made no sense.
How could so many spiders have jumped a big, fast-moving beetle, and how could they have gotten through his thick plate armor so quickly? He seemed to have gone from precision flying to apparent death very suddenly, even suspiciously suddenly. It slowly dawned on me that I had just been outwitted by a bug playing possum, so I Googled “mites on beetle” and discovered something fascinating.
