You certainly do
These are examples of attitudes and posts that if i write i would receive negative reps & penalties.....
And also if i show any objection to this type of attitude against myself i would again receive the same behavior from some members here0 -

Today, most mammals possess dichromatic vision, corresponding to protanopia red–green color blindness
54 minutes ago, Genady said:15 minutes ago, Genady said:I understand this explanation. What I am asking is, how can we know that this is WHY they have it.
i like to say it and talk about my point of view on the evolution and was waiting to discuss this thing in another topic i had questions about evolution like the one i had in the Eyes & Ears topic but im really afraid to ask them because when i ask some questions you people think im saying ( this thing i think is absolutely right and i dont accept any other theories to alter my view ) i had a lot of other questions about evolution but im really held back my the attitude of some users here i prefer not to open up and ask them .........as i have learn in my short stay here even asking things that other people dont agree would make some trouble for me ......
Oh by the way
If i said this.... : The second link, I don't trust. It is too simplified
I would not be treated very nicely as people telling me its a scientific site not a place to your personal thoughts.....🥲
Right now i saw Mr swansont has gave me this...
...for a clip that i mentioned kindly if you ignored the first couple of seconds....and it was talking about what i wrote about but i have to bear a penalty that never expires........but they insisnt on giving me an unexpirable penalty ...........eitherwise..........
And here you just have a topic that says examples of camo. and i wrote what i thought is a nice example........you keep saying why you talk with out evidence.........
And i suggest you to read a little about countershading ...........
And the answer is no.............i have A+ in biology.......what do i have to do with you A+ man ? you said evidence i gave evidence.........You say examples of camo i gave my Example...........
You know what i dont really a have a strong and stable mental state and think ill better leave here before the repellent atmosphere here makes my situation worse.........I learn a lot of things in my short stay here.............thanx to all people who helped me know more...........
Oh the last word i still cant forgive you for thikning im a flat earther in this topic......even though i said man i maybe an idiot in relation to people who have A+ 's and have studied in good universities of the first world countries.......... but im really not that dumb to be a flat earther........
But people insisted on that i was wrong and im trying to prove the globe isnt a sphere........
You people * not all of you but most of you dont even listen to the questions people ask you ............
* in my short stay here ill give the credit for the user with best manners & attitude to Mr or Mrs. Studiot ....try to learn from him/her

Color blind doesn’t mean grayscale.
“In all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors. Cats and dogs have two kinds of cones, which are sensitive to blue and green light. This means they have a useful level of colour vision. The level of colour vision in other animals depends on the presence and types of the cones.”
Also:
“The only animal that has been confirmed to see only in black and white is a fish called a Skate. This is because it has no cones in its eyes.”
Thanx
9 minutes ago, Genady said:BTW, fish do not have "their shadow under their body."
I ddint mean the shadow cast on the ground i meant the part of the body thats in shadow ( the under side of the animal )

Its called counter shading
Its also used in military camouflage.........

1. How can one test this hypothesis?
Test what ? test that their bellys are lighter than their backs ? or are you asking about the colorblindness ?
19 minutes ago, Genady said:2. Is it a fact? How many is "many"?
If you go research about it i think that a lot by a lot i mean more that 50-60% of vertabrates species are .........Except primates & a lot of birds....they mainly can see colors......

The main reason a lot of animals both terrestrial
And marine............
Have white or @ least light colored belly's is that many animals are color blind and thus see only a grayscale of other things.........
And when the light source of nature is always from above....... the under side of animals... tend to be in shadow.....and seen darker......than their backs so they have evolved like that so the light shaded bellys cancel their darkness because their in the shadow under the animals body.......and other animals attentions as less likely to be drawn to them
As you know if it was not like that the difference in the shade between their backs & bellys would catch eyes.......

We all use heuristics. In that regard, you’re not wrong
I read it deeply and with concentration today .........and for my self i really dont think i use them.......but i cant judge and give points to my elf somebody else who is on constant relation with me must do it.....
I dont want to derail the thread for the second time.............but ......i have a question
in the brain the Medulla Oblongata * have i wrote it right ? does the automated physical jobs like when you want to learn to do something as you are learning it your brain is in charge..................and after you have learned it the automated process is handed to the Medulla O. like driving or cyclingIf im right Is the heuristics like that too ? Only in the mental phase

OK, this looks like the Fourier series I've mentioned. Any wave can be decomposed into a sum of weighted sinusoidal waves. Each component wave behaves independently, and the resulting wave behaves as their sum. The component waves do not affect each other.

No, you didn't upset me. By vague I mean that answers depend on what you refer to as wave and as wave carrying wave.
i had a book in early 90's it illustrated in it that certain radio waves can act as a carrier wave for other waves
It was some thing like this...

What do you mean by vague ? Did i Upset you again ?

By the way a question
Can waves that have a higher energy level thus can move further and through denser objects.........carry other waves with lower energy levels with in themselves....
And carry those other waves to distances or through objects that they themselves normally cant ?
Basically can waves carry other waves ?

No, it didn’t. You must have pasted the wrong link. Your link went to video entitled “Didnt realize how fcked we are” and it spoke about reading thoughts or some such.
If you would ignore that part that also was talking about a device that could decode brain activity waves and reconstruct approximately and not precisely the thoughts the person had...........it was a 10-15 second of talking about that...then the rest of the clip was about the thing i mentioned .
54 minutes ago, swansont said:members should be able to participate in the discussion without clicking any links or watching any videos. Videos and pictures should be accompanied by enough text to set the tone for the discussion, and should not be posted alone
I think you as a mod could see the parts of the post i edited.............i wrote some of my ideas about it but i feared that the mods or other people would be upset and tell me dont talk about your ideas with out evidence......so i edited the post and preferred to not write anything......to see what others think and say about it.....

But because I am lucky enough to be using an old pc the website did not work for me just displaying the address and a blank page.
I downloaded it and put it in one of my telegram channels if the Mods would give me the permision i could put the link here.....

I'd like to know what you've posted, but I can't, because
a) I'd have to follow the link, which is against the rules, and
b) the link is a URL shortener, which is not advised to follow.
I dont know why it was removed it was a video showing that using a wave detector device the send & receive Wifi signals & waves normal ordinary modems can be used like a radar to picture a 3d model out of your house and any stationary or moving object that is in it......including humans living in it.......

Language is also about the way we think of things. Even two people from the same culture speaking the same language often mean somewhat different meaning by the same
I'v always thought many people simply only hear some sounds when some one else speaks.....................And if i developed that ability in my self my mental health would be much better..............

Yes, at any point in spacetime where the two waves are present, the resulting field is the sum of two fields. Each one of the two waves continues unchanged.
They do not "collide". Their effects simply add up.
Thanx....
Do physical waves like sound waves that are compressional ( longitudinal ) waves also follow that ?

40 minutes ago, Genady said:
Yes, they just go through each other.
No, they don't interact.
Dont they add up to each other and form a form of result wave @ the point of collision ?

The thought of extracting sound from objects brought up some other questions
When two or more electromagnetic waves collide they mix with each other And form a result wave @ the point of collision and then they continue to go as they were before the collision right ?Is it possible that after the collision they each hold information about the collision like the place ( distance from the point of observation ) of collision or the characteristics of the other waves it had collided with ?

A factor you need to consider is that the Moon does not orbit over the Equator, and it's orbital plane is ~ 5 degrees from the ecliptic.
This video gives an idea of the Moon's path over the Earth. The camera tracks wit the Moon, and the Red dot shows where the "Earth-Moon joining line intersects the Earth's surface. It not ~100% accurate as I made the Moon's orbit exactly 28 sidereal days long to keep it simple.
The path starts North of the Equator, drifts South and then back again.
Thanx i mentioned that incline in the 3rd post
Why dont posts have numbers here ?

If it were possible, then police work would be very easy. Take a piece of a suspect's skin and listen to all their past conversations.
Police ??
If its gets done we have to re write the whole political history of man kind.....(* and maybe thats why we havnt done it yet or maybe we ordinary people think we havnt ) ..........And we get a whole new level of comprehension of the natural history of our planet and maybe the rest of the universe...............
1 hour ago, iNow said:Depends on how you define language. Apes, wolves, whales, elephants, squirrels, birds, even ants and bees have active communication systems.
Hmmm you know @ first certainly .......humanoids were @ the level of sounds too........
But later they ( we ) have evolved up to having words.............first maybe names for things........then later verbs ( words for acts ) then we must have tried to put these together and form sentences.........thats the point where basic and simple grammar was forming.......
I meant that point......by having a language..........
By the way another question we have discovered or in other words distinguished letters later right ? when we were developing alphabetical systems .......was that the time people had to separate each sound in all the words and assign a symbol for each ?
When i was like 10 i knew english besides my own language ( Farsi ) i once noticed that the word ( Worm ) and its word in Farsi ( KERM ) sound a lot like each other also i remember thinking that those words sound squishy and mushy like the locomotion of the worm and thus i thought maybe these two words have a common root........I remember having a little note book that i wrote all the words that i though sound a lot like each other in both languages........but i lost that note book ..later

Just now, Genady said:
No. I don't think we do.
Even if we could, we would recover a sum of all sounds that hit the object throughout history. That would be just noise.
Well if such a thing is possible that would be the first & early stages of that tech.............maybe developing it would lead to the ability to separate the sounds...

I don't think we know.
how about our selves ? do we know when we have developed our first languages ?
And another question although it may sound bizzare and may make people say its a scientific site and you are not allowed to talk about your thoughts here....
Do you think we would some day be able to extract recorded sound in objects like fossils........i mean sound is a physical gas wave............it would certainly have effect on anything it hits.............right ? Do we have any scientific evidence that sound waves has effects on molecules of solid objects ? And those effects could be read ( extracted ) later and decoded back to sound ?0 -
Had the other Homos like Neandertals or Erectus's who lived as recent as like 100 - 200 K years ago ever developed languages ?
And if yes how did we know ?

So for the subsolar point are these right ?
One year = 8766 hours so 360/ 8766 so 0.041 Deg/H Subsolar point travels W to E
One day..... 360/24 so 15Deg/H Subsolar point travels E to W
So speed of SS point = 15.041 Deg/H = 1674.64 Km/H
