Adding a rotating portion to the station would be introducing a gyroscope. Doing so would be problematic.
Take a bicycle wheel, spin it on its axis and then try to tilt it.
How much fuel are you willing to spend to keep the station oriented the right way?
How much mechanicals are you willing to spend money on to steer the solar panels if you aren't going to be using thrusters to orient the whole station?
How big is your budget? Funding isn't unlimited. You need to make choices. If you go with a rotating section, what are you going to eliminate elsewhere to compensate for the cost?
The only lack of thinking in this case is on your part.

From "Good Omens" by Terry Pratchett and Neil Gaiman:
Along with the standard computer warranty agreement which said that if the machine 1) didn't work, 2) didn't do what the expensive advertisements said, 3) electrocuted the immediate neighborhood, 4) and in fact failed entirely to be inside the expensive box when you opened it, this was expressly, absolutely, implicitly and in no event the fault or responsibility of the manufacturer, that the purchaser should consider himself lucky to be allowed to give his money to the manufacturer, and that any attempt to treat what had just been paid for as the purchaser's own property would result in the attentions of serious men with menacing briefcases and very thin watches. Crowley had been extremely impressed with the warranties offered by the computer industry, and had in fact sent a bundle Below to the department that drew up the Immortal Soul agreements, with a yellow memo form attached just saying: "Learn, guys..."
There are typically signs that say that there are cameras. Indeed, in the Wallgreens down the road, there is a TV monitor facing the doors as you walk in just to say "Yes, if you shoplift, we've got tape"
This? This isn't about shoplifting. There are also no signs or any indication that this is going on.
I was just having difficulty wrapping my head around how to finish a 5-meter-long dimension to half a millimeter. Even finding a reference length to compare against would be difficult. I was just having difficulty wrapping my head around how to finish a 5-meter-long dimension to half a millimeter.
It's not difficult if you have the right measuring equipment. Nikon has a laser measurer that does very large volumes (aircraft sized) and is pretty darn accurate over large distances. It's expensive, but if the guys in the shop measure stuff like this on a regular basis, it's a big time saver.
In the old days, there were other methods that weren't nearly as convenient for such large distances.
Fortunately for everyone working in all shops and labs everywhere, STP, standard temperature and pressure, is room temperature and the sea level air pressure of a sunny day. Heat/cool the shop to 20C or 68F and you won't have any problems. A couple of degrees either way doesn't make much difference unless you get into really large pieces. And any small shop worth its salt will have an inspection room that is climate controlled to plus or minus a degree. If you do have a problem with the climate control, you can look up the temperature coefficient of the material you're using and adjust accordingly. But that's bogus. Close off a room, stick an HVAC unit on it with a good thermostat and you're good to go.
"Ordinary machining techniques are good down to 0.1%"
*a dark cloud appears above my head* I'll try to bite my lip and be civil about this..1% for a 25.4mm part is.0254mm, (1 inch, and.001 inch respectively, for SAE). Charles Babbage was able to meet that tolerance with the tools of the time - the builders of the modern Difference Engine empirically found they could indeed do so. When the Difference Engine was built using his old plans, they decided to take on the argument that Babbage couldn't possibly build his Difference Engine due to lack of technology. They found that argument to be bogus. Depending on what you're doing, that kind of tolerance these days may as well be plus or minus a mile, especially if you're sending something to be ground. With superfinishing (Supfina Inc., North Kingstown RI (my childhood hometown)) you're looking at microns or smaller.
Affordable glass scales and ballscrew retrofits have even made manual machining a lot more accurate. Drill 2 holes 500mm apart plus or minus.02 mm? All I've got is a rebuilt Bridgeport with glass scales? I've got AC that doesn't blow directly on the machine tool and shrink one side of it? NO PROBLEM.
Am I insulted? Yeah, a little bit. Bring coffee into the shop next time. Thanks.

Apple can trademark an "iPad," because when you append letters and mis-spell, you no longer have an English (or other language) word. I (and the vast majority of people) have no problem with this.

I'm unsure when the use of purely English words was allowed, but it was a bad idea and it's caused no small amount of trouble since then.
For Apple to stretch the concept and claim the word "pad" for themselves is abuse of trademark and they should be slapped for it if they try to bring it to court.
Slashdotters get upset here at Monster Cable for suing an indoor golf business (and a lot of other small businesses that can't afford to defend themselves) by Monster Cable claiming the use of the word Monster in the name is exclusively theirs.
