I don't. It is one of those things that I can look up because I don't need to know them.

Who says I remember them? I didn't say that. It's not difficult, though.

I don't. It's a rainbow. It's colorful. Isn't that all I need to know?

People really need help remembering the colors of the rainbow? I guess I must have drawn about a thousand rainbows when I was a little girl, so the order of the colors is probably burned into my retinas.

Aren't gay people implanted with some sort of rainbow chip to help?

But does the red go on the inside or out? What about with a double rainbow?

The only rainbow song I know isn't very helpful as it goes "Red and yellow and pink and green, purple and orange and blue. I can sing a rainbow, sing a rainbow, sing a rainbow too!"

Okay. I never remember. I know the colors on the second rainbow of a double rainbow are reversed and that it's dark inside (under) a rainbow but I always forget the order.

Are the colors of a double rainbow really reversed? It's not just two regular rainbows next to each other?
dab Survey Qualifier
(reply to Enheduanna) posted 3-Jan-2008 5:28pm  
The second rainbow is made by the light taking a different path (two reflections instead of one) through the same water droplets. I'm not entirely sure why this reverse the order but it does. here and here are some decent pictures.
Enheduanna Survey Central Subscriber

If it's another reflection, it makes sense that the order would switch. The first rainbow must technically be the opposite order of the colors as they entered the water droplet, no? The wikipedia article on rainbows gives what seems to me a fairly useful explanation.
dab Survey Qualifier
(reply to Enheduanna) posted 3-Jan-2008 6:24pm  
The light enters the water droplet not separated by color. There's a bit of refraction both entering and leaving the raindrop which separates the colors somewhat (like a prism) but I think the primary separation happens at the reflection. There's a maximum angle to the water's surface, after which there's no more reflection. This maximum angle varies by the light's frequency.

Hmmm, the Wikipedia article doesn't talk about this, so maybe it's just the refraction after all. It does show why the second rainbow has the colors reversed though. The double reflection makes the light sort of do a loop-the-loop around inside the water droplet going the other way from the primary rainbow.

The initial refraction inside the drop is what I meant by "as they entered the water droplet." The most useful explanation was in the captions under a couple of diagrams, although the part about how the wavelengths separate said something about it as well.

I don't remember the technicalities of the prism. I'd have to look it up.

It's not that I have to remember the colours of the rainbow in order to get through the day, or even that I need a method for remembering them. It's just that I recall the mnemonic I was taught as a child, back when knowing the colours of the rainbow seemed somehow important. I still remember SOHCAHTOA from high school maths and I've not had to use that for over 15 years.

I don't know how I missed out on hearing the rainbow mnemonic, since it seems to be pretty ubiquitous. I do remember Please Excuse My Dear Aunt Sally (or just PEMDAS) and My Very Earnest Mother Just Sold Us Nine Pies, though. I recall using SOHCAHTOA, but I don't remember what it means!

It's trigonometry. Tells you which calculation to use depending on which of the sides of the triangle you know the length of and which angle you're trying to find.

Sine=Opposite+Hypotenuse, Cosine=Adjacent+Hypotenuse, Tangent=Opposite+Adjacent.

"My Very Earnest Mother Just Sold Us Nine Pies" is interesting because for the entire time we were both at school it was wrong. The orbit of Pluto is so different to that of the other planets in the Solar System that between 1979 and 1999 it was actually closer to the Sun than Neptune.

I was taught Silly Old Hens Can't Always Have Their Own Acorns - I'd still fall back on that if I had to do trig.

I have a feeling mnemonics are going to play a very significant role in my education over the next few years (and beyond) smile

Do you know Midnight ( I think it's actually MIDNIT)? I remember it from an episode of House M.D.

I hadn't but I just googled it and only found references to it on House fan pages. It would have to be a for a pretty specific set of conditions if you start your history taking by looking at metabolic disorders though. I've mostly come across medical acronyms for memorising anatomy so far - probably because my course isn't very clinical so far - apart from SOCRATES which is used to take a history of pain (site, onset, character, radiation, associated factors, time, exacerbating/relieving factors, severity).

I just found an actual medical mnemonic website (http://www.medicalmnemonics.com/). I'm not sure how mainstream they are as a lot of them are user-submitted (presumably by other doctors). SOCRATES gets a mention.
