  1. Engineers in academia seem to do very similar research when compared to scientists (albeit a bit more on the application side), and I'm sure they apply the scientific method more that the engineering design process when doing research.

    So, are engineers who do such type of research considered as scientists?

  2. But for the large majority of kids, more freedom means playing more video games or hanging out with friends. And I am not sure that is a good way to get started in life.

     

    If someone were to convince these students of how amazing learning is, they would spent more time in self learning. But, school gets in the way of that. If a student doesn't like school for whatever reason, he would have an aversion for the things taught there and would be frustrated with it. Thus, he would look to other activities as catharsis. So, school is the root problem, not the students.

     

     

    The education system is more interested in catching fish for students so that they can be fed at that time and can pass an exam, whereas what students really need is to be taught how to catch the fish itself, so that they can feed themselves for a lifetime.

    To me the whole ideology of our education system is broken. It's time we fix this, as we are wasting the most valuable resource, our human resource.

  3. I want to do research, especially in an area like nanotech or materials. So, in regards to this, should I do a Phd in chemical engineering or chemistry for a research career in these areas?

     

    I'm leaning a bit to chemE because nanotech is engineering after all, and I have heard that learning chemE gives you more of an all round knowledge. But, then again, in chemistry I would get to learn a lot more about organic, inorganic and other stuff. But, I'm not totally sure and would like to hear you opinion.

     

    I'm currently doing my ug in chemE.

  4. We hardly know how the brain works. We still don't have a clear picture as to what intelligence is in the brain. Nor do we know what traits ( memory, wisdom, common sense ) make up intelligence. That is why I find it absurd that we try to measure and grade people's intelligence with a number (or a letter if it's a grade) , when we don't know how it works. It is funny how we try to measure something so varied with the same yardstick.

    What is your take on this ? Is it a wrong practice to be measuring a person's intelligence based on a number/letter ?

  5.  

     

    In Indian languages, a word which is equivalent to 'Science' in English is used as synonym to 'Knowledge'. Also, worlds most ancient script 'Vedha' has synonyms 'Knowledge' and 'Science'. So I had strongly in my mind that Science=Knowledge.

     

     

    Not exactly. You see, there was no exact word science in the modern sense in Sanskrit or in any other Indian language. That is because they did not follow our logic of obtaining knowledge ( science ) and followed a different one. Just that, nowadyas, meanings of words such as Vigyan ( in Hindi ) have been altered to better suite these languages for the modern world. They originally did not mean science or knowledge but something different ( stuff in vedic philosophy )

    But, your point still stands. Science comes from the latin verb 'to know' and the word for knowledge. But, the modern meaning of science is different from the root word. That is because, before the Renaissance, science actually meant knowledge. But, after the Renaissance, we developed techniques such as scientific method, etc. People realized these methods of getting knowledge was more important than the knowledge itself. So, the meaning of science was changed the modern one.

    A rough history lesson on the word science :).

  6. An other possibility: oil's index matches that of paper more closely, avoiding diffusion at the many interfaces.

     

    This is pretty much the reason. Paper is made of cellulose which has quite a bit of air in between ( in the gaps ). Now when we put oil, it fills those gaps and reduces the scattering at many of the air-cellulose interfaces. Oil's refractive index is not that far from cellulose, so that helps making it more translucent.

  7. It depends on how anyone wants to consider science as. Processes, experiments, methods, enterprises, etc were not considered as science until recently. They were considered makers or keepers of science. The very meaning of the word 'science' is 'knowledge'.

     

    For example, Person B can call an animal XYZ as 'Cow', while Person A calls PQR as 'cow' .. if there is no common understanding.

     

    Well that is your definition, but, that does not mean it is the real one. Science is the methods and not the facts. I like to call the facts as the 'products' of science

  8. From ET's point of view, I'm an alien.

    Does that make me a God?

     

    I am not talking about it from the alien's point of view. I am talking about it from OUR point of view, where our society seems to be more placing their aspirations and fears on this alien myth that we are constructing, much like how the ancient people did with what they called god.

    It seems small, but, I feel that it is gaining momentum, because of all the movies, subculture and myths we are creating around these aliens. I mean they even have their own pilgrimage site, Roswell :P.

    Maybe I am over-generalising, and this applies to few fanatical people only. I'm not sure, that is why I want to discuss this with you guys.

  9. Everytime, the nucleophile is "the one attacking" and the electrophile is "the one attacked".

     

    Not necessarily. What you are taking about is nucleophillic addition reaction and not addition in general.

    In electrophillic add reaction, this is reversed. In this case the substrate ( the one being attacked ) is the one that is nucleophillic and the electrophille is the reagent ( the attacker ).

    For eg, -C=C- is a nucleophillic center ( so it is substrate ) which can give electrons to an electrophile ( reagent ), like H+, and this adds to the double bond. This is nucleophillic addition.

    But, in a C=O group, the carbon is an electrophillic center due to action of oxygen. So, a nucleophile adds to it. This is nucleophillic add.

  10. Science is the set of facts and reliable beliefs, which are useful irrespective of time and place (Science Definition).

     

    Well, that definition is completely wrong. Science is the pursuit of knowledge rather than the knowledge itself. To quote from wiki :

     

    Science is a systematic enterprise that builds and organizes knowledge in the form of testable explanations and predictions about the universe.

     

    Edit - swansnot ninja'd me :(

  11. It can't be done with 100% efficiency, but, the efficiency is getting better. In fact, the show Ecopolis on the Science Channel ( called Discovery Science where I live ), did an episode on this, where some guy had developed the technology by which sunlight could be transferred to the interior of a room with really good efficiency. Also, check this article if found : http://www.ecogeek.org/solar-power/246.

    I think the tech for this is there, it is just a matter of cost.

  12. In the past, people would say that everything is based on god, as they could not explain it in any other way. They made elaborate stories about god(s) and this created a sort of culture and identity of the people. God for people was a way to express their ambitions and desires as a society of controlling nature.

    I see a parallel between that and the modern day notion on aliens. They have come to signify our fears as a technological race as well as our hopes of better tech and intergalactic travel. Also, many unexplained things are blamed on aliens. Just like the notion of God, aliens have seeped into our culture, and we are creating modern day myths such as chupacabra, little green men,etc.

     

    My question is that are Aliens the new god, in the sense that we are placing our hopes and ambitions in them and creating myths about them, just like we did with God before.

     

    NOTE : I am NOT asking whether God/Aliens exist. I am talking about how they have been/are being represented in our culture. Please do not debate if God/Aliens exist or not.

  13. Give maths a another try. You may have had a not so good experience with it in school, don't let that make you hate maths. Try Khanacademy it is really good.

     

    If you really don't want to so something with maths, then maybe biology and chemistry is a good bet. But, I still feel you should give maths another try, you might discover that you are actually good at it. Buy books and learn maths online, don't be discouraged by your math grade in school.

  14. The big companies usually make the same games for consoles as well as PCs. We have plenty of games for the PC as DevilSoluton said. But, we are starting to see a shift away from the PC.

    I think it is because that PCs can have wide ranges of hardware capabilities and it becomes difficult to make a game with heavy graphics for all of them. Also, PCs have different OS, which adds to the trouble.

    In that sense, consoles are standardized, so it is easier to program for it

  15.  

     

    But speaking of India: what benefit do you have from your national government? Why would your state governments not be able to carry out all those tasks?

     

    Well issues such as sharing of river water and stuff like that, among other things.

  16. What is statistical mechanics ? Has it got something to do with probability ? Why are they different statistical mechanics like Bose-Eistein, Fermi mechanics ? And is the Kinetic Theory of gases related to this mechanics ?

     

    I know, I have many question tongue.png , I just can't find any good material on this online.

  17. Wow, I think Phi is a little harsh on faith. It has nothing to do with denial or anything, as you put it. To me, people need something to trust in their lives and need a source of comfort. Blind faith serves this purpose. And I think that is about it, I think.

    It is mostly a play of chemicals in our brain, that is why it is such a powerful thing.

  18. There's definitely an exothermic reaction taking place. I'm just skeptical that the first video didn't use something besides glue and cotton to initiate the combustion.

     

    I agree. I found it hard to believe at first as well. So, what kind of exothermic reaction due you think it is ? I cannot find any answers online.

  19. I agree with the main picture you sketch, but I would suggest that humans just naturally want to be part of a group, and that therefore the creation of a unique identity is not so much a conscious decision of anyone in particular, or even of the group as a whole. Instead, the creation of that unique identity is just a part of being human.

     

    Living in groups has been the common practice literally since history began, and probably long before that... So, we could therefore perhaps agree that, to the best of our knowledge, it is a part of being human to be part of a group?

     

    I see this question in this thread not so much as a question as "why do we need differences", but more a question "why should we all become part of the same group"?

     

    What single benefit would there be to have a world-government? I don't think I cannot see any. A world government may be able to keep the peace, but I don't see why the UN wouldn't be able to play such a role. They wouldn't need much more power to be effective.

     

    It seems however to me that the main thing that has kept the peace lately in Europe is just one general thing: Shared mutual interests. Whether these are military (against the commies) or economic (European union) does not matter. You don't actually need a powerful united government for that.

     

    I think it is more interesting to learn to accept our differences peacefully, and actually enjoy the differences. Cooperate where it is necessary, practical or profitable, and just leave it at that.

     

    IMO there is a pressing need for a world government. Only a world government can deal with threats such as global warming and terrorism.

    It will also help the poor countries and make a more even distribution of wealth.

     

    If we form a world government we actually promote our differences, rather than destroy. This actually will help bring us together, while still maintaining our difference.

    You can take India as a good example. There are many states each with their own language and culture. When we talk to people in our state, we say that we are more this city/district of that state. But, when we talk to people outside of different states, we say that we are from this state. When we are outside our country, we say that we are from India. So, it is like a layer-cake of identifies, where each identity is retained.

     

    I find this a good example to what we should be as global citizens.

     

    And, BTW, I feel that when we have different political entities, we cannot live together peacefully.

  20. I really don't like how tightly the camera is pulled in as the cotton catches fire. It suggests to me that an open flame somewhere nearby was applied to provide combustion. I think this video is faked.

     

    I think this would lead to a major recall of the product if it were true. Have you tried this yourself?

     

    The smoke from the superglue is dangerous, so no way I'm trying this. Well it's on wikipedia and many other site, so as surprising as it may seem, it is legit.

    is another video if you are interested.
  21. I have heard a lot of talk about how the development in language was a turning point in human evolution. But, why exactly was it ? And what areas of the brain got bigger due to language.

    On a side note, did other very 'human' traits such as culture, art, rationalism come about due to language ?
