They are frequencies, it's the same order because red is the lowest frequency and violet is the highest frequency. When light hits water its path is bent based on it's frequency.

There used to be 5 colors until Newton

Reply to ELI5: what is the point of chewing food thoroughly if your stomach will digest everything anyway? by Dacadey
Ever chucked a huge chunk of sugar block into water? note how its extremely slow to dissolve?
Same with food, the more you chew, the smaller the food bits become, this overall increases the total area your stomach acid can interact with the food.
When you don't chew, and just swallow an entire brisket full, it will take a long time and too much energy for the body to process, and in turn, decide that it's not worth the effort/energy and just pass it out.

When people first began to type on mobile phones they were slow, now people can type at 100's of words per minute, same thing applies to almost any physical skill. We got good over time.

Fun fact. The Japanese don’t have a separate word for ‘green’ and ‘blue’. They named the part of the visible spectrum that, to English speakers, is between what we call ‘green’ and what we call ‘blue’. What we call a ‘green light’ (on a traffic light) they call ‘blue light’, what we call ‘green apple’ they call ‘blue apple’ etc.

Reply to eli5: What is a firewall? by This_Caterpillar_330
Computers communicate to each other over a network. To enable this they open ports where they listen to communication.
A firewall is something you put somewhere in the network to block access to those ports for computers that should not have access.
The firewall can be on a computer or between a network and the internet.

Aside from being hard to swallow..
You have chemicals in ur stomach called enzymes that break down the food so your body can absorb all that nutrients. When we chew food, we increase the surface area of it, meaning we break it down to smaller pieces. When the surface area is increased, the enzymes in your stomach are able to break down your food much quicker and easier. Think of it like if you put a 10g sugar cube into a cup of hot water and put 10g of sugar crystals into another cup of hot water which do u think will dissolve first? It’s gonna be the sugar crystals because all the sugar molecules can easily be reached rather than the cube because it still has to break down as it dissolves. Chewing works the same way. So technically you don’t have to chew your food because the enzymes in your stomach will break everything down anyway, but it’s nicer to have a healthy digestive system that will give you pain free toilet times ^^

This is more than just artistic. Blue and red are close to an octave apart (a factor of 2 in frequency).

The brain fills in all kinds of information. Not just colours.
For instance, our eyes have multiple blindspots. But the brain fills in the details - by making em up.
Want to test that? Hold both your thumbs straight out. Look at the left one. Slowly move your right one to the right. And OMG did it disappear? Surely not? No, thats the blindspot where the optic nerve meets your eye.

That's also true for icb-cars, you can use the motor and transmission to brake, at least with manuals, I don't know about automatic. Still, regen braking has greater stopping power.

Thanks that's a nice comparison.

No.
GDP is like your annual wage for countries.
But personal asset is ALL that person is worth.
Its kinda hard to say the guy who has 2 billion in asset if you count everything, he owns is richer than the country that makes 1 billion every year.

You can name all combinations and then it's a regular 27 character language. That doesn't make it so, that's an abstraction. Every language can be deconstructed into binary, but Morse has an obvious ternary system that is closest to its actual usage.
Dot dot is not valid. Dot space dot IS valid. Space is not valid. Seven space is valid. Do you need me to draw up the formal language rules?

>Honest question, who is still using Morse code and in what capacity?
Amateur radio operators. They use it in conversations and passing information on daily nets. You can tune around the spectrum and hear it 24hrs a day.

Amateur radio operators around the world. I know plenty of guys who never talk on the radio but do code daily. It's just a preference.

Yes, every rainbow looks the same. Rainbows are an illusion caused by the way light bounces around inside spherical drops of water. The angle light is bent as it passes from air to water and back again depends on wavelength.

Different wavelengths are bent at different angles, which is why you always see them in the same order.

The brain doesn't fill anything in. It has 3 possible inputs from the 3 rod types. What we call colors are just combinations of those inputs.

The idea that the rainbow has seven colors actually comes from Isaac Newton, who greatly advanced our understanding of light. He understood that it was a continuous spectrum, but made many analogies to musical notes. The wavelengths of the “seven colors” are proportional to the wavelengths of the notes of one octave of a major scale.

American Morse code is more complicated as it has two lengths of dashes and two lengths of inside a character spacing https://imgur.com/0MIkiUh.jpg
