Tenchi Muyo 1: Engineer's disease

"Engineer's disease" is where the viewer can't stop thinking while watching a mindless show. Like Tenchi Muyo.

This picture has always bothered me. If the the main cables of a suspension bridge are severed in the middle, the towers will lean out, not in.

Why are Saturn's rings and Saturn's stripes not in the same plane?

NO, no, no... It's not Ryu-oh's key, it's Ryu-oh's ki. As in 気, which means "spirit, life force".

UPDATE: One thing that isn't wrong with that second picture is how dark it is. Saturn's orbital radius is between 9 and 10 AU, which means it receives about 1% of the sunlight that Earth does. If one of us was on one of Saturn's icy moons in full sunlight, it would look like night with a full moon. We could see, but we probably could not see color.

All probes intended for the outer solar system (defined as "everything outside of Mars") have to carry nuclear thermal generators for power, because solar cells don't cut it.

Which is kind of a problem for Heinlein's book "Farmer in the Sky". I love that book, but there are a large number of reasons why it isn't practical. (Which I'm sure Heinlein knew, too; he was telling a story, not doing an engineering design.) There's no way you could do open-air farming at that distance from the sun. Jupiter varies between 4.9 and 5.2 AU, which means on average it gets about 4% of the sunlight Earth gets. That would be less bright than deep shade here, and most crops will wither and die in deep shade. If you wanted to grow plants on a terraformed Ganymede, you'd have to use greenhouses and artificial lighting.

What am I doing posting at 3:00 AM? I get punchy and start free-associating.

A different problem with terraforming Ganymede, leaving aside the sheer difficulty of it, is that after you melted all the ice and released all the gas, you'd end up with one hell of a lot of ocean. If you could somehow raise the temperature of Ganymede to Earth normal and keep it there, there would be no dry land anywhere. The now-complete and much-recommended web comic "A Miracle of Science" handled that correctly. All cities would have to be floating.

And now I'm going to bed.

Glitch report: the screencaps are being truncated by the comment sidebar on the mainpage.

20 years ago, nobody would have understood that sentence.

That's what Pixy refers to as a "notabug". It's behaving as it is supposed to.

It's the reason why I modified the site format to get rid of the sidebar in individual comments, but on the main screen it is supposed to truncate.

The only solution is to scale the images, but I don't want to do that. If you want to see the full images, you enter that specific post.

3 "...Should be "Ryu-oh'ski...."

I always figured that Tsunami was talking about Ayeka's headdress, which is the key to her ship, Ryu-oh.

In other words, Tsunami is telling Tenchi that she's located Ayeka aboard Souja, Kagato's ship, by locating the key to Ayeka's ship.

4 Cowboy Bebop handles the terraforming of Ganymede (and for that matter all moons of Solar System) with Hyperspace Gateway that pipes in sunlight. And in the show, Ganymede is an Ocean habitat where all of the cities are afloat.

5 Ah, so you already know about Miracle of Science?  I'd long considered recommending it to you, but declined to, since you seemed ill-interested in recommendations.

Actually, you'd be able to see colors pretty well at Saturn's distance from the sun.  1% of sunlight may not sound like much, but it's still far brighter than the full moon-- about 1,000 times as bright, in fact (a full moon is about 1/100,000th as bright as sunlight).  1% of "normal" sunlight wouldn't be all that different from a typical indoor room lit by electric light.

You certainly wouldn't be doing any farming or solar power with it, though...
