November 7[edit]

(Re)Inventing the wheel[edit]

Structure of bacterial flagellum.

Some time ago I watched a short video on an octopus travelling slowly across the bottom of some maritime region. I was rather stunned to realise that it used some of its tentacles to create ad hoc / temporary "wheels" for locomotion. Two (?) tentacles were "rolled up" into a sort of helical structure (like a short cork screw) and the animal then "unrolled" these two wheels between head and substrate whilst preparing more tentacles for locomotion.
Unfortunately, I missed to save a reference. I would be curious to learn if octopuses habitually use this method of "driving" on the bottom of some maritime habitat or if this specific individual has just done a quantum leap to invent the wheel. Thank you for any help! --Cookatoo.ergo.ZooM (talk) 11:06, 7 November 2018 (UTC)

Nature "invented" the wheel long before that. See:
--Guy Macon (talk) 05:39, 8 November 2018 (UTC)
I've seen similar footage. Good stuff. Octopi are pretty intelligent as invertebrates go. It's not surprising they have figured out how to use their tentacles in various ways. ←Baseball Bugs What's up, Doc? carrots→ 01:31, 9 November 2018 (UTC)

Can't do a stereogram[edit]

As12stereo c2.jpg

This is apparently some sort of stereogram, but I can't do it. I have an easy time "doing" images like File:Stereogram Tut Random Dot Shark.png, but for some reason the same technique doesn't do anything with this picture, and when I focus my eyes normally, I can't see any of the repeating patterns that are generally necessary for seeing the underlying parts of such images. How is one supposed to see this image and others like it? Nyttend (talk) 02:10, 10 November 2018 (UTC)

This looks like one that you need 3-D glasses for, the color-based ones they used to use in the old 3-D movies, before they perfected the polarization-based version. Our article seems to be at anaglyph 3D, which is not a name I really recognize, but it seems to be the right concept. --Trovatore (talk) 03:52, 10 November 2018 (UTC)
Okay, I've never seen such a movie (and never understood what to do with the paper or cardboard 3D glasses), or maybe I would have recognised the situation. Thanks for helping me understand better. Nyttend (talk) 05:21, 10 November 2018 (UTC)
FWIW, I have such a pair of red/green glasses (designed for printed images) to hand, and they work somewhat, but not very well, for the picture at either the size as rendered here, or larger as from the originating file.
It appears to me that the red components are 'overexposed' and/or have 'bled' beyond their original extent. I suspect somewhere in the chain of reproductions between the original and the image on my screen, the colour balance or some other dimension(s) of the image has/have been distorted. There may also be a mis-match between the colours used in and reflected from paper-printed 3-D photos versus those coming from a lit computer screen. {The poster formerly known as 87.81.230.195} 2.218.14.42 (talk) 16:11, 10 November 2018 (UTC)
I'm no expert but as far as I know, if you don't wear 3D glasses and you view a flat surface which is just an ordinary screen or paper and not a hologram then the only way to get a proper 3D effect is a pattern which almost repeats left-to-right, like in File:Stereogram Tut Random Dot Shark.png. It works when your eyes focus on different places but your brain is interpreting it as if they focus on the same place. A hologram works by emitting different light towards your left and right eye. This requires a special medium. 3D glasses work by filtering light so your eyes see different things. Virtual reality headsets work by having two screens showing different images to the eyes. Actual reality works by your eyes seeing an object from different angles. PrimeHunter (talk) 19:25, 10 November 2018 (UTC)
  • Red/Blue 3D glasses: [1]

  • Polarized 3D glasses: [3]
  • Active Shutter 3D glasses: [[4]
  • Cheap versions of some of the above: [5][6][7][8][][][][]

(I don't know whether there are different kinds of polarized 3D glasses or whether the design is standardized. Does anyone know?) --Guy Macon (talk) 17:22, 10 November 2018 (UTC)

can someone help me with a question regarding the BC Government?[edit]

Hi. I'm a disabled adult who lives in British Columbia and I get income assistance though a program called the ministry of social development. I'm wondering if there is a way I can expand my funding and I don't currently have a social worker. can someone please suggest something to me? Thank you! Poodlesun (talk) 03:45, 10 November 2018 (UTC)

This seems to be the place where you would go for such inquiries. I would start there. There's a phone number for general inquiries, and there are also links that take you to locations of in-person offices where you can meet with someone to discuss your situation. I hope that helps! --Jayron32 04:46, 10 November 2018 (UTC)
Or possibly the Canada citizens advice.--Phil Holmes (talk) 08:21, 10 November 2018 (UTC)

November 14[edit]

Popular perceptions of NHS doctors[edit]

There appears to be an opinion in many European countries, and in the UK, that doctors in the UK are less capable than doctor in most of continental Europe. Is there any particular explanation for this? Is it, in some sense, true? If so, why?--Leon (talk) 13:46, 14 November 2018 (UTC)

UK based, I've not encountered that. In fact, quite the opposite, there's enormous admiration for our doctors. There's a widespread perception that the NHS underperforms due to lack of money and/or inefficiency, so for example, the UK lags behind leading nations in things like cancer survival league tables. --Dweller (talk) Become old fashioned! 14:06, 14 November 2018 (UTC)
Maybe World Health Organization ranking of health systems in 2000 can provide some insights. EniaNey (talk) 15:05, 14 November 2018 (UTC)
With full respect to you and the WHO, no league table would be able to unpick perceptions of doctors nor whether said perceptions are fair or not. --Dweller (talk) Become old fashioned! 15:52, 14 November 2018 (UTC)
I'd at least like to see some references to support the assertion that the OP states. Having worked in the UK NHS for much of my life in a clinical and managerial position I have yet to see any evidence either way that doctors in the UK are any better or worse than doctors in the continental health services. How would that be measured? Richard Avery (talk) 10:48, 15 November 2018 (UTC)
I do not claim to have, and my assertion is that there is such a perception, not that it is true. I queried a surgeon at a London hospital whom I know personally, and he agreed that it is a common perception, but does not believe that it is well founded, and does not claim to know its origin.--Leon (talk) 13:34, 15 November 2018 (UTC)
Yes, but even THAT is an assertion without evidence. You've put a claim on the table (that UK doctors are perceived as inferior) and then assumed that we all accepted that as true, and THEN asked us to explain why it is true. That's a plurium interrogationum error (I.E. the "When did you stop beating your wife" problem), which is what Richard Avery is objecting to: We can't answer the second, included question until the first question is answered. First we need to answer "are UK doctors perceived as inferior" before we can answer why they are; obviously if the first question comes back with "They aren't", it obviates the second question as nonsensical (that is, if you never beat your wife, you can't have ever stopped!). SO, back to the point: You've made an assertion based on two people: you, and one other person you asked. I'm not sure that's evidence enough for us to move forward on the assertion as acceptable. Instead, please provide us with more substantial evidence than "Me and my friend agree on it". DO you have the results of an opinion poll or other similar reliable broad-based research so we can move forward from the assertion, and focus on your main question. --Jayron32 18:54, 16 November 2018 (UTC)
I suppose this and this is some evidence. I will not lie, I have read nothing that could be called a "reliable" source concerning this opinion, let alone why it might be widespread.--Leon (talk) 22:26, 16 November 2018 (UTC)

November 15[edit]

Where did the Shuttle Carrier Aircraft refuel and what was its landing/takeoff requirement?[edit]

I read the article at Shuttle Carrier Aircraft, and have some questions I did not see there. The article states that the carrier only had a range of 1000 NM. Where did it stop for refueling on trips from California to Florida? Also, what are the carrier's runway requirements for takeoff and landing compared to a unmodified 747? RudolfRed (talk) 02:42, 15 November 2018 (UTC)

If you look at List of Shuttle Carrier Aircraft flights, it looks like Kelly Air Force Base is the most common intermediate stop, with other Air Force bases being used from time to time. --Carnildo (talk) 02:54, 15 November 2018 (UTC)
@Carnildo: Thanks for that article link. RudolfRed (talk) 16:36, 15 November 2018 (UTC)
One glaring omission from "List of Shuttle Carrier Aircraft flights" is the 1983 trip to the Paris Air Show and a grand tour of Europe - I watched pass over my back garden in London. Didn't anybody else notice it? Alansplodge (talk) 22:51, 15 November 2018 (UTC)
Good catch! It's mentioned in Shuttle Carrier Aircraft#Design and development:
By 1983, SCA N905NA no longer carried the distinct American Airlines tricolor cheatline. NASA replaced it with its own livery, consisting of a white fuselage and a single blue cheatline. That year, this aircraft was also used to fly Enterprise on a tour in Europe, with refuelling stops in Goose Bay, Canada; Keflavik, Iceland; England; and West Germany. It then went to the Paris Air Show.
The provided reference How Does the Space Shuttle Fly Home?] (Slate, 2005-08-09) says:
Since the early 1980s, NASA has carried out 51 shuttle-transport missions, including a trip across the Atlantic to take the Enterprise to the Paris Air Show.
[Update, August 10: Many readers have been wondering how the Enterprise made the long journey across the Atlantic Ocean to the Paris Air Show. The shuttle traveled over the water by making the (relatively) short trip from Goose Bay, in northeast Canada, to Keflavik, on the southwestern tip of Iceland. The Enterprise then continued on to England and West Germany before reaching Paris.]
But it doesn't give dates. If we can find them elsewhere, they should certainly be added to List of Shuttle Carrier Aircraft flights. -- ToE 23:26, 15 November 2018 (UTC)
Now added:
"May 16-June 12, Enterprise, tour of the United States, Canada and Europe. From Edwards Air Force Base to Peterson Air Force Base, McConnell Air Force Base, Wright-Patterson Air Force Base, CFB Goose Bay, Keflavik Naval Air Station, RAF Fairford (20 May), Cologne Bonn Airport, Paris Air Show (arrived 24 May), Ciampino Airport, Stanstead Airport, Ottawa International Airport, Scott Air Force Base and Sheppard Air Force Base".
I suspect that we're missing a second refuelling at Keflavik on the way back, but nobody mentions it. Alansplodge (talk) 15:23, 16 November 2018 (UTC)

Question about the show TRANSform Me[edit]

Where can I watch online or where can I buy it? Poodlesun (talk) 06:37, 15 November 2018 (UTC)

If you can't find it on Youtube, you could try asking the show's makers: Left/Right Productions. There's a contact form on their website. DS (talk) 20:33, 15 November 2018 (UTC)

What font is this?[edit]

I'm looking to find out what font this is, where it says "GARY R. HERBERT," "OFFICE OF THE GOVERNOR," etc. Thanks! 204.126.146.202 (talk) 23:59, 15 November 2018 (UTC)

Here is a link to the article in question for those trying to answer this question Gary Herbert. MarnetteD|Talk 00:09, 16 November 2018 (UTC)
Sorry, what image are you referring to? Not seeing it in the above article. Drewmutt (^ᴥ^) talk 00:15, 16 November 2018 (UTC)
The Sans-serif font on the sign on the side of the car here [9] is probably Arial or Helvetica. DroneB (talk) 12:45, 16 November 2018 (UTC)
The sign on the car has the simplified letter "G" of Arial - see comparison of Arial, Helvetica and Monotype Grotesque. Alansplodge (talk) 15:51, 16 November 2018 (UTC)

My money is on Century Gothic, very commonly used in such contexts. Drewmutt (^ᴥ^) talk 21:33, 16 November 2018 (UTC)
No, in Century Gothic the capital F and E have two and three (respectively) horizontal bars of equal length, in the pdf, the lower resp. middle ones are shorter. The font identifier at www.fontsquirrel.com finds a match with media gothic, which seems about right to me. - Lindert (talk) 22:02, 16 November 2018 (UTC)
It's engraver's gothic. Many fonts have imitated this style. See [10] for example. 78.0.230.255 (talk) 00:16, 17 November 2018 (UTC)
