Reply to comment by Super_NiceGuy in ELI5: Why are the colours in rainbows in separate lines? by Oheligud
This one is kind of hard to explain without pictures... or in a timely manner. Basically when the visible light goes through the medium that splits it into the rainbow it changes angle, and part of what determines how much the angle changes is the wavelength. The reason the order and ratio is the same is because the rainbow is basically the colors ordered from longest to shortest wavelength spead a based on the change in wavelength. For instance, if you pointed a light that contained all wavelengths but yellow at a prism the rainbow would look the same as it would with all colors with a missing band where the yellow would be because the absence of yellow light does not affect the wavelengths of the other colors. That last bit is actually super important in a handful of scientific fields.

So Saturn and Jupiter are made of roughly 90% Hydrogen and helium and are defines as gas giants. Uranus and Neptune have a lot less, about 20%, and havr more heavier elements like oxygen and nitrogen. These are called ice giants. Both are so big and have such high gravity that they have rock/ice cores with strange physics we can only hypothesize about.
The gas giants, after you get past the atmosphere, have such high pressure that the hydrogen becomes like a liquid metal. If you remember your periodic table, elements in a column all have similar properties. The column Hydrogen is in is all metals except hydrogen. The pressures are great enough to force out hydrogen's metal properties. It likely goes straight down to the rock/ice core.
Ice giants dont have enough hydrogen to form a liquid metal hydrogen layer. Instead, after their atmosphere comes a mantle of water, methane, and ammonia ices. These proceed their rock/ice cores.
Now, these are hypothesis based on the planets' composition and properties. Fairly good ones too, though we still have some unknowns.
Now, as to the why this is: the current leading hypothesis is thay during the formation of the solar system, the solar winds pushed more the lighter elements to the outer system while heavier elements were mlre resistant. That left with mostly heavy, rocky material for the inner planets and mostly light, gaseous material for the outer planets.
Hope it helps
Edit: initially wrote "row" instead of "column", fixed

Reply to ELI5: Morse code is made up of dots and dashes. How did telegraph operators keep from losing track of where one letter ended and another began? by copperdomebodhi
Because you don’t hear the individual dots and dashes. After a while, you hear them combining into words. That’s how I learned it. It starts to sound like a monotone song.
Source: me. I used to be able to send and receive upwards of 20 words per minute. That was many years ago, and I’ve lost a good bit of it. But if I hear a snip go by in a movie or something, the words still jump out.

>it eventually compresses to liquid and solid.
Note: in Jupiter's case, it compresses to a hypercritical fluid and then various solids we've been trying to recreate using diamond anvils and explosives.

Cold water does not help, warm or room temperature water helps more. When you pour cold water the body gets the signal: COLD, avoid area, protect the organs. It pulls blood away and delays the repair response. Even if you are in pain initially(2-3 seconds), use warm water it also helps with not leaving scar tissue

The thing with morse is that there's gaps between each letter and if you can't tell where those are you are screwed because:
.- is A . is E
- is T

Are they differennt from:
Dot - length 1.
Dash - length 2 (so could be considered 2 dots together).
Space between dots/dashes - length 1
Space between letters - length 3 (so could be considered 3 spaces together)
Space between words - length 7 (so could be considered 7 spaces together)
If you recognise the dot and dash as 2 different things, then should you not also recognise the different length spacings as well?
If you were considering Morse as a computer encoding, you'd recognise 4 symbols - Dot-space, or 'high-low', for a dot, Dash-space (High-high-low) for a dash, 'low-low' (following the 2 above with a trailing space) for a letter delimiter, and 6 spaces for a word delimiter. But we'd still call this a binary encoding.

It does not help to heal, it just stops further damage.
After burn there still a lot of heat which continues to damage tissues. thus you need to remove remaining extra heat.
Note: one should use room water around 20C. Using cold water especially from freaser will make more damage

Thank you. So the dot/dash is just a translation of 'VHEISSU' ??? That opens up so many new avenues to that album and it's followup, Alchemy Index

jupiter and saturn are mainly gas, neptune and uranus are better classified as ice giants and pluto is icy but is not giant

I tried, the right one never disappeared.
A better test. With both eyes open you do not see your nose. Close one of your eyes and you nose appear.

That's not exactly true. The word 'midori' means green, and has been in use since the heian period (8th century) but was considered a shade of 'ao' ( blue) until early twentieth century, where midori has been more frequently used to describe what English speakers would call green. You are correct about traffic lights, and about certain green plants being called 'ao'.

Like surstromming. How hungry, and how determined do you have to be to eat that shark that as a society you figure out the many steps needed to render it edible?

According to Wikipedia, it’s the name of the album (Vheissu) done by singer Dustin Kensrue.

No, you are correct that as the pressure increases, it eventually compresses to liquid and solid. And bathe cores of the planets are made of heavier elements that are solid anyway. But they are mostly gas.

Perhaps saying "interprets" rather than "fills in" is more accurate when talking about colours. Either way the brain processes that information and what we "see"is the result. Also I think it's cones that are more to do with colour rather than rods so I got mixed up with that.
