Physics: Post your doubts here!

[badrobot14]

failure would depend upon one's aims, one person's success could be someone else's failure i guess, however if you look at the aim of improving the human condition then the vast majority of the people in this regard are failures no matter how much money they have, even if they pay money to distribute medicine, food,etc to the poor, fact remains that "no scientists, no medicine"

I was reading the interesting conversation and this part made me wonder... Why do you think in dichotomies... Like no scientists, no medicine.. but then no funding, no scientific research/scientists as well.. so ppl paying for good are doing good in their capacity and we are thankful for them just as we are to those researching on medication for the right reasons... After all we do live in a world of interdependence...

we really need a thread for those topics that does not get closed like for science students one

 

[studyingrobot457]

similar questions have been asked and asnwered, simple the evidence of a brain can be done via MRI Scans, PET scans, CAT scans, SPECT scans

there is evidence because it is based upon the basics of physics and the number of technologies that would not be in existence if they were lying is too great, the camera, x-rays, pet scans, GPS, radio and other types of signals, none would be there, you want to deny all of science okay sure, no one is stopping you

still, technology could be witchcraft, some ancient tools found by modern people etc etc etc, if I would use your logic, then existence of technology doesn't prove that science is real, similarly you say existence of such sophisticated and accurate system does not prove existence of creator , I am not denying the fact of science,I am showing you how stupid this sounds if it is compared to real life, just open your mind just say in your heart if you, a super intelligent deity exist, the show me a proof of your existence

peace.

Great! So basically before the invention of MRIs n CAT scans (let's say a 1000 years ago) people didn't have brains coz they couldn't yet see/prove them?

read the thread For Science Students, enough mistakes have been pointed out and in anycase there is no science in the quran since it does not use the scientific method, it says things vaguely just like any other religious text, since religion was one of human beings attempts to explain the causes of natural phenomenon

No.. actually with your limited mind you think they are mistakes.. you tell everyone to have an open mind n reaserch but you never use your head or your heart to consider what they post.. to consider that you can be wrong....
The way you even debate with someone on quran is so superficial.. you start posting links instead of succinct coherent argument...
And about your scientific method..the Quran never claims to be a book of science.. it is a communication for people and guidance from the creator... That's why you don't find your scientific method there... Rather it is organized like no other book.. in a profound way to serve it's purpose... There is an ancient saying; the speech of a king is King of speeches... And that's what Quran holds if one is ready to dive into it with a sincere heart looking for guidance... Even the science that you find in it is not too inform you about science but to discuss more important things with you.. like why are we here and where are we headed and how does it all makes sense...

Still this proves nothing, this si, not an n evidence, this can all be a fabrication of bunch of people callling themselves 'scientists'

well for that you would need to prove that it is a fabrication
this idea and similar ideas have been discussed for example in the book The Demon Haunted World - Carl Sagan
if it was all fabrication then none of the scientific progress every thing you use has resulted from scientific progress would have been there
just pick up a basic general science book and you will see the explanation
furthermore to test if it is all fabrication you can also develop products on your own, that is why schools have science exhibitions to SHOW students how science is done practically
a lot of detail for this can be found Cosmos: A Space Time Odyssey (2014) this traces the basis of inventions
https://www.iau.org/public/themes/astronomy_in_everyday_life/

there are multiple other sources you can check for yourself, if you are still not satisfied well, then i guess it is your problem

After all we do live in a world of interdependence...

strictly speaking dichotomies would be in set theory but i get your point
but if you do not want scientists and medicine, the death toll would be very high and the birth rate would be very low, just look at any plague in and before the medieval times versus any viral infection in today's time for example ebola was contained with relatively fewer deaths
simply read the history of medical science and diseases for questions like this Cosmos: A Space Time Odyssey

Like no scientists, no medicine.. but then no funding, no scientific research/scientists as well..

.. so ppl paying for good are doing good in their capacity and we are thankful for them just as we are to those researching on medication for the right reasons... After all we do live in a world of interdependence...

doing good in one's own capacity would be of limited benefit due to limited level of expertise of each individual and the increasing complexity of scientific questions that are being answered
people doing research need funding at any level, for this you should study the history of economics to understand how resources have been allocated historically , medical research is very expensive for individuals (even the richest) so that is why corporate organizations are there, to fund even the richest and medical research or any other is a continuing process, so some form of organized resource allocation is needed .... don't schools discuss these issues anymore?? we used to discuss this since the 5th or 6th grade

also medicinal research cannot stop at a certain level because nature keeps on changing, also the improvement of the human body is only limited by the limitation of research, there is no end point

additionally scientists keep on trying to promote science to educate the public and also so that more scientists can be raised, it is the politics that limits the funding for science, that can only change if the lay-person appreciates the sciences and raises children to become scientists, more scientists are also needed because AI will ultimately replace mundane jobs
go through Big Think there is some discussion regarding this
in this post "For Business Students" there is is a video by Ray Dalio that explains the economic machine

a good book for this is

still, technology could be witchcraft, some ancient tools found by modern people etc etc etc,
peace.

read message #16971 it addresses witchcraft etc

for the ancient technology/tools there is:-
https://en.wikipedia.org/wiki/Pseudoarchaeology
https://en.wikipedia.org/wiki/Graham_Hancock
https://en.wikipedia.org/wiki/Erich_von_Däniken
all their ideas are rejected by peer-review

if I would use your logic, then existence of technology doesn't prove that science is real
peace.

actually technology and experiments that work do prove science is real, this has been addressed in message #16971

similarly you say existence of such sophisticated and accurate system does not prove existence of creator
peace.

specify these "sophisticated" and "accurate system" without examples i cannot know what you are talking about

I am not denying the fact of science,I am showing you how stupid this sounds if it is compared to real life,

please specify "how stupid this sounds" ... what exactly are you referring to?

I think this address nothing, if I don't trust scientist however you try to convince me ,I will say your evidence is incomplete, you are doing the same thing with Muslims anyhow, so it is a matter of choosing whom you want to believe, although both sides can be equally wrong, and don't give me links to some peer-views, I don't trust them you see (using your method of proof) no matter what you bring, you can not have evidence for me for science to be true, could be all a lie

most schools show stuff that was known hundreds of years ago, strictly speaking in the name of everyday phenomena or alchemy, so practically even if you show me show a camera work, still not convincing, read about John Titor and his time machine

see no matter what you try, there is no clear cut evidence for science without involving personal claims and opinions, same goes for religion and next time you reply be short and meaningful

well considering i am skeptical enough to doubt any claims of "perfection" shows that i am open minded

those who are never even willing to doubt the claim of "perfection" of their set of beliefs and use it as a starting point of entry to a religion or an organization, are the ones with a closed mind

that is why science/scepticism is the better way forward, it keeps on improving and rejecting any ideas that are proven wrong

a simple example is the "the big crunch" it has been rejected in 1998 after it was found that the universe has accelerated its expansion, this is the point dark matter and dark energy were discovered, now new evidence is needed to understand dark matter dark energy and the same goes for any research in any area of science

And about your scientific method..the Quran never claims to be a book of science.. it is a communication for people and guidance from the creator... That's why you don't find your scientific method there.

quran claims to explain the natural phenomenon as do many other religions that came before it, this is because before science there were only "beliefs" that people had to explain natural phenomenon and those explanations in the light of science have turned out to be wrong, read The Demon Haunted World - Carl Sagan and the criticism of Bucaili's book The Bible Quran and Science
http://www.telegraph.co.uk/culture/...-Arabic-Science-by-Jim-al-Khalili-review.html
there are many other articles and websites you can use as well, another approach you can try is use the tafaseer and compare them to the scientific explanations of natural phenomenon

then people of religions use their texts and connect it to science to prove the "truth" of their religion and this is where it fails detailed scrutiny which is why Buccali's book has been rejected

Rather it is organized like no other book.. in a profound way to serve it's purpose....

doesn't mean much, all books are arranged in a specific manner, some people like it some people don't, some like me are indifferent until the claim of "science in the quran is made"

There is an ancient saying; the speech of a king is King of speeches... And that's what Quran holds if one is ready to dive into it with a sincere heart looking for guidance... Even the science that you find in it is not too inform you about science but to discuss more important things with you.. like why are we here and where are we headed and how does it all makes sense...

okay but again it doesn't make much of a difference, people are entirely capable of finding their own purpose direction in life, the meaning life or its direction does not need to be handed over by someone, independent rational thought should be used to come to one's own conclusion, those who want to follow one book sure go ahead no one is stepping in anyone's way

[studyingrobot457]

see you are now contradicting your self (instead of teaching yourself lol) you said that in order to believe in any thing there has to be an evidence, and when we give you an evidence, you just say it is not a clear one, and then when I carried on to show you this is the exact same situation you said it your problem, thus I can summarise in a simple sentence

a simple skull cracked open via injury is easy evidence, so dissection is not necessary, apart from that mummy dissections and dissections by scientists before the MRI, CAT, PET scan, etc were carried out

apart from that the DNA of homo sapiens has been the same, so ancient humans would have brains apart from that there are fossilized brains

you simply rejected all of science by saying that even if the technology works on the basis of scientific findings you will still not accept it, my role is not to change your mind, it is to provide you with the information available you can then either accept or reject it

After doing objective research on both sides, I came to conclude that religion is not a scientific matter, there are proofs, but not evidence, if God was evident, what would be the point of testing us at all?, anyhow, I think you are an ex-Muslim , if so, at least keep the testimony of faith with ya, you know, if you have it you are not losing, but if you don't have it , and god did exist, oh uh, so stop being a closet atheist and just be a weak Muslim, at least this keeps your virtue in your country

and by the way, there is nothing in the whole observable universe that is 100% certain, in other words, there is no clear-cut evidence for anything, what is the evidence that you do exist, all this technologies and techniques are indirect measurements, even eyes, sounds etc are indirect, and can be affected by other factors

read this at least https://en.wikipedia.org/wiki/Haptic_technology, so if itis possible to fool the brain, other factors can be fooled
