    Sorry, I don't remember the details of how it supposed to work. Perhaps

    Ohhh   i thought......you said

    In fact, many years ago I studied biology, and got Master Degree (M.Sc.) in biology. One of my favorite courses was Animal Behavior, which I passed with A+. I remember well

    When  writing to others :   Sorry   / Suppose / Perhaps......

    When answering me  :   In fact / I studied / Got masters / My  favorite course / I passed with A+  /  I remember well

    The second link, I don't trust. It is too simplified, for kids.

    Its  simplified   not  lie ified or wrongified

    The first link, I didn't see there anything about "more than 50-60% of  vertabrates  species  are  .........Except  primates & a lot of birds....they  mainly can see colors......

    Today, most mammals possess dichromatic vision, corresponding to protanopia red–green color blindness

    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.”

    https://www.vetwest.com.au/pet-library/can-animals-see-colour/#:~:text=Only one animal cannot see in colour&text=The only animal that has,no cones in its eyes.

    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

    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 )

    I don't think it is so. Did you do that research? Do you have a reference to such a research?

    Test this explanation of why they have white/light belly. "cancel their darkness because their in the shadow under the animals body" etc.

    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 ?

    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......

  5. The  main reason a lot  of  animals  both  terrestrial

    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 

    https://asana.com/resources/heuristics#

    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  cycling

    If im  right     Is the heuristics   like that too ? Only in the mental phase

    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...

    Communication-System-33.jpg.f7bf094104f83de798a95f55d847a148.jpg

     

     

     

  8. 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  .

    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.....

    I tried the link, and was taken to a comedy website.

    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  ?

  13. 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...............

    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

    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...

  17. 6 minutes ago, Genady said:

    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 ?

  18. 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
