1. ## Time Travel Revisited

maybe it would be good to wait @HallsofIvy 's assessment, but to me ; hearing "highly" word only reminiscents my romantism or colors rather than mathematics. surely,it is not a mathematical expression I am highly romantic hahah ha
2. ## What do words mean?

no. but not sure. again as far as I know this is being taught or known so in a brench of science named "cybernetic"
3. ## What do words mean?

as far as one of my old (now retired) hodja says "in fact,words can both mean or not mean anything. Becase that type of communication is caused by cryptic transmission" I also add: " this cryptic transmission is commonly based on local paradigms"
4. ## the units corresponding some mathematical functions

ok , if you mean I would be free to select any unit depending to the type of problem,then I think..my question has been definitely resolved. yes, if so,I would just say: MANY MANY THANKS
5. ## What are you listening to right now?

density of emotion
6. ## the units corresponding some mathematical functions

mm ,if I understand correctly you express this one: "the function itself does not come with any unit or not being calculated with any unit, but you also express that anyone can give any unit to it." if you would like,I can upload the picture,but now I think it does not seem like a requirement,it seems the question is being resolved. I mean something like these: after drawing the graph of function of sine. (for instance with R) this will bring you a classic graph of sine function. but for instance you probably said that I could mark π/2 cm , πcm , 3π/2cm, 2πcm, etc..at each points. (But R does not write so,I mean if I would,I can add cm or mm or any else unit) Right? for instance with what type of unit the π length should/will be defined? (if I understood correctly,you say that I was free..to select any unit (?)) π is only a quantity ,we normally need something to define (for instance here) the length but with which unit?
7. ## the units corresponding some mathematical functions

The object I refer is that any object created by any function (by turning it around another function that offset of that function. (but here that function is :sine function)) (to better understand,I recommend this : first turn that function around the offset function and fill the inside of tunnel with glass.object is clear?? wait please ,I shall draw something by my hand..
8. ## the units corresponding some mathematical functions

consider these: how were we calculating these object's volume? --->> an abject has vivianni window at its one side and other sides are regular. --->> an object that created by turning $y=x^{3}$ function arpound x=y function (360 degree) I underline the obtained object's lengths. these objects have to have length.
9. ## the units corresponding some mathematical functions

I think I do not mention about that. and you seem like you are not aware from calculating integrals (e.g.: calculation of volumes, and mmm specific integrals (e.g. surface integrals and or green ,stokes , diverjans theorems) sorry,I do not allege anything ,but your comment cause me to suppose something in this way.
10. ## the units corresponding some mathematical functions

Thus...this means that,we cannot calculate x axis' length that sine function passes over it (at 0,π , 2π , 3π..etc) in that, could you assume please we turn sin(x) 360 degree around sin(x) + t (t here is any natural number) how will/must the length of the object be measured?
11. ## the units corresponding some mathematical functions

Hi, I might have misunderstood somewehere.not sure. This function Asin(ax) is periodical function and the period here is $\frac {2\pi}{|a|}$ the values of peak can be set by A. Exactly the thing I am asking is that whether ax could be defined with centimeter units. pahah why not: not for french but I am sure that the circle on Gold Lira (Turkish Republic Gold ) is turkish.

and, so...?
13. ## the units corresponding some mathematical functions

I had previously thought that this topic would suit in physics but decided in maths, however if not, I apologise in advance. Question: can we describe the unit of x in sine function in centimeter? for instance sin(x) is equal to 1 cm, where x is equal to π/2 centimeter. Some external comments: This question was a part of one of projects. Unfortunately I am not good in physics in the current position although I am willing to learn it but I saw (almost) no problem regarding its mathematical side. (because in fact as we know that sine function's domain set was R and value set was [-1,1] Maybe I am again failing because here the values in domain sets are angles) Thanks in advance.
14. ## What are you listening to right now?

an interesting musics type from old culture coming from mesopotamia region going on POPular style...
15. ## What are you listening to right now?

a bad musics but good ratio of listening in comparison to european style 你 好！ a good musics but low listening ratio. mid/high quality!
16. ## What are you listening to right now?

.....:::alejandro:::.... an old and ...very bad video but a good musics
17. ## what does "scientist" mean,exactly?

ya yes. but sometimes people or more correctly folks may be bigoted (i.e. incorrect). this presumably in somewhere may be extended to wide range of people,which is really significant count of people. For instance, here in turkey,I am sure that many people believe or act as you have to have a relevant and expected title (e.g. associate professor ), education and most seriously and very interestingly : regular salary and work. (in other words "an approved academic job at any university" the last one to me is very interesting and I think that this can be accepted as a type of bigotion. because that is incorrect. First, under that that one complies the official rules (i.e. regulations), and deals with any contexts and spends sufficient effort and has expected knowledge,then this should be enough. But in many times this does not happen. I agree to charonY if she/he implies/shows the regulations, but surely, pofession is a bit different. I know several languages, but , there are many professors who do not know even one foreign language or who are not qualified on this issue, which is directly affecting the quality of any academic research.
18. ## what does "scientist" mean,exactly?

I have not wanted to enroll any master or/doctorate program but I deal with and would continue dealing with scientific contexts and research. simply,I would like to do the research on whatever I want and it seems I am a bit pragmatist (because I do not want to deal with anything that would not provide any efficacy anymore). Thus can we accept me as a scientist?
19. ## Graded potentials & Consciousness

hi, although my question is way clear,I could not find a proper written (academic) material to prove it. Question/Query: " I (state/claim) that in order to obtain consciousness we would definitely need an action potential, but not a graded potential because ... a graded potential is just along with a neuron rather than jumping over neurons one by one. because its name is graded potential. ....." I need a published material (academic please). Almost all of texts (articles , book chapters) I read mentioning with both descriptions but do not clearly use the sentence I would see ,like above. I fear ,I am lacking.. but any help will be appreciated. ( similar meanings : 1) graded potentials cannot cause perception. 2) Action potential is mandatory in order to say "perception exists" 3) when a graded potential jumps over one neuron to another ,its name is not a graded potential anymore, its name an action potential )

21. ## Weather in your hometown (split from Climate change and global warming)

haha. both op's opening paragraph and this sentence seems a bit cute. to me, I agree to op. it seems really strange. Here in turkey it is not raining this autumn. but I ...I am positive almost always these days. Thus this issue currently does not bother me (until it be regional (but here) chaos or global chaos.

23. ## can we trust R in regard to drawing graphs?

yes correct. and this is an important problem to me. (and yes, both axes will/should be shown with the same units (e.g.: mm (x), mm( y) or cm( x) , cm(y)) I try to understand the characters of functions. but simply showing two graphs almost same one of them between -2,2 and the other one -100,100 is a problem in my work. what is more,presumably this Pogramming does not provide 3D plotting. to sum up this comment, I should nevertheless exceptionally thank to you for providing information.
24. ## can we trust R in regard to drawing graphs?

thank you @timo for commenting. to begin with, I think I am not good in plotting. but simply need to see some or wide range of graph of functions. thus, if you believe that it would worth,then I will pass the programming level for learning it. but for now, it seems a problem exists above, the range of y (f) function (value set) does not seem with same ratio. Therefore, again the graphs you drawn are not realistic. (meanwhile, I only used this commands) curve(x^3, -5, 5) curve(x^3, -3, 3) but same graphs. (you of course shown the numbers corrrectly, but those numbers are not with their real height) maybe, I have lack of information about how to plot with R,rather than criticizing it, but not sure.
25. ## do you believe that "collaboration" teams are more successfull in engineering than individuals?

mmm, probably this sentence means that if any team's member wants ,then he/she can do something else at the same time working in the team.
