The AH-64 Apache is a tough bird. But it’s not tougher than the entire *Earth.* Consequently, you should avoid ramming the Earth with your AH-64…

No, not *that* Orion. The Crew Exploration Vehicle space capsule Orion. The plan currently seems to be to lob it into low Earth orbit with a Delta IV Heavy, and then boost it an extra 3000 or so miles higher so that it will come screaming back in to survive re-entry and be recovered and reused.

It is, of course, unmanned. Which is sad, because I’m sure there are more than a few extremophiles who would *pay* to ride in it.

A related video shows part of the Orion manufacturing process: a big chunk of aluminum and a robot with a sense of purpose.

So, some folk are arguing about whether or not Jesus of Nazareth was a real historical person. Leaving aside whether or not there is evidence enough to conclude that Jesus was real… it seems to me that if the argument is important to you and you want to win the argument, you really aughtta argue rationally and honestly. Take, for example this article by trying-to-sell-a-book author Bart Ehrman:

Did Jesus Exist?

Where the guy arguing that the evidence says “yes” says this:

The alleged parallels between Jesus and the “pagan” savior-gods in most instances reside in the modern imagination: We do not have accounts of others who were born to virgin mothers and who died as an atonement for sin and then were raised from the dead (despite what the sensationalists claim ad nauseum in their propagandized versions).

Ummm. Anybody catch the logical weakness there? Here’s a hint: he’s claiming that we should reject the claims made about supposed savior-gods because those claims are apparently just made up without any evidence.

Ummm…

Regardless of whether that’s a valid point (and I think it is), it should be noted that what’s right for “proposed god A” is right for “proposed god B.”

Additionally:

You may not trust Rush Limbaugh’s views of Sandra Fluke, but he certainly provides evidence that she exists.

True. But then, it would a hardly be a new thing for, say,  a journalist or an author or whatever to simply make stuff up and be believed. And this is today, in an era when every claim can be checked, sooner or later. Thousands of years ago, a claim could go unchallenged for *years,* and when challenged, the hunt to find the evidence might require a month on a boat and a season on a camel.

On a purely rational level, a claim that “Mr. X” existed, no matter how widely believed, bears the burden of proof, not the counter claim that “Mr. X” did not exist. Often the burden of proof is an easy burden: while there are no living eyewitnesses to Abe Lincoln, there are a *vast* number of eye witness accounts, as well as photos and even a death mask. For Julius Caesar there are a number of eyewitness reports, and sculptures and coins and such made while he was supposedly alive. But for Jesus Christ, there are four contradictory books written, apparently, by eye witnesses a few years after his putative death. And that’s it: everything else is hearsay.

How reliable are those four books as historical records? Well… they describe a superhero with magic powers. Consider a modern UFO sighting: which is more reliable…a  report that reads, in effect, “I saw a strange light in the sky,” or the one that reads “I saw an Arcturan battlecruiser hovering on anti-gravity powered by dark matter kittens?” Even though the reports may describe a witness account of the exact same event, by adding very unlikely details, the more interesting report becomes less believable.

If you want to believe in historiocity and divinity of Jesus, hey, great. But flawed logic and overblown rhetoric is not a rational way to convert non-believers…. though it may well be a *successful* way. I’ve talked to more than a few people who have tried to convince me to convert because “if you don’t believe, you’ll go to Hell.” The problem with that line (beyond the fact that it makes God look like a petulant psychotic dick) is that it will only work if you already believe. If someone does not believe in Hell, threatening them with Hell shouldn’t make them believe… just as someone who doesn’t believe that that bar of soap in your hand *isn’t* a death ray won’t be converted to the belief that it’s a death ray just because you threaten to blast them with it.

Use it to zap a crater in the sidewalk, and maybe you’ll get some converts.

A 1969 concept from the Martin Marietta Corporation for a teleoperated construction robot. The robot was not fly-floating, but instead was to be mounted to the end of a “serpentuator.” This was a long robotic arm akin to the Canadarm, but with more joints. This was to support the Apollo Applications Program, which eventually transformed into Skylab.

The robot was vaguely anthropomorphic, with a TV camera for a “head” and two arms with manipulators hands. The grippers featured piezoelectric sensors which would provide feedback regarding grip pressure. A second camera was fixed to the robot’s “chest,” and what might be regarded as legs featured simple rings at the end which would latch onto studs on the object being worked on.

The basic concept has survived to the present, although the more modern designs tend to looks rather less blocky.

They are all terms blocked on the Chinese social media site “Weibo,” sort of a Chinese Twitter.

Blocked on Weibo

There is a list of 378 words and terms that are blocked for searching. A lot of them are obvious (political references, terrorism references, sexual references), at least in terms of what you’d expect a totalitarian regime to ban; others are non-obvious, and I’m guessing there must be some sort of idiomatic explanations that don’t translate directly.

And then there’s stuff like “food allergies” and “allergic rhinitis.” Bwaa??

The expedition will begin this weekend. So if you want to get onboard, now’s the time. The deadline to pay by check/money order is Thursday; Paypal, Friday. This is so I can get my finances in order before leaving. After Friday, investment will be closed.

A half-hour film shot by Chevrolet in 1936 showing the auto manufacturing process.

Looks like an impressive mix of “dangerous” and “soul crushingly dull.” Still, there’s an impressive amount of automation shown here. Obviously nothing as smart as a robot… anything goes wrong, or goes out of kilter, and the system would need a human to directly intervene. But it’s still kinda cool.

Might be that by 2036, cars might be built in far smaller, virtually unmanned factories like the one shown in “Minority Report,” where  cars were completely built and assembled in a facility the size of a  modest warehouse. And in a few decades more… who knows, the distant descendant of the MakerBot might be a cubical frame that fits around the edges of your garage. When last year’s model becomes boring, you park the car in your garage, get out, and tell the AutoMakerBot to “attack.” It tears the car to bits, storing the various materials in separate bins… and then builds the new model.

The UAW, of course, will have a hissy fit.

This is the sort of sci-fi reality that I can see coming along fairly reliably. Not as spiffy as flying cars and rocketships, but still fairly cool. Of course, this sort of technology plays more directly into the culture of shallowness that sees people going bonkers for the newest iCrap, and would require little or no more effort on the part of the user than it would take to use the newest bit of consumer electronics – unlike what would be required of those who would patrol the spacelanes. Still, I’d love to have such a system. Might not make me a new model car… but I just might spend some time making a surprisingly detailed CAD model of a car-sized rocketship.
