  1. Two-edged Sword of Technology on Has Any Creative Work Failed Because of Piracy? · · Score: 3, Insightful

    ...the real damage is done in works which are never created in the first place due to the perception that piracy would make them financially irrelevant.

    This was my initial thought too. However what I don't understand is why the technology sword does not cut both ways. It is true that technology makes it far easier than it has ever been before to pirate material but it also makes it far easier than ever before to produce that material. Unlike the past there is no need to risk a massive budget on every new act. Give the riskier acts smaller budgets and see what they can do with them. After all if they are less popular they will probably also be less pirated and the ones which do take off can give you a great return on your small investment.

  2. Times Change on Colleges Stepping Up Anti-Cheating Technology · · Score: 1

    If you wouldn't agree to it yourself, why would you inflict it upon others?

    Times change. As a professor I'm not happy with the increasing anti-cheating methods being deployed and do my best to design exams to make it hard to cheat by design rather than by technology. However I am also not happy with the huge rise in cheating that we are seeing at Universities. The philosophy I would like to follow is the one I was used to as a student myself: you are basically trusted to some degree but when you seriously violate that trust by cheating the consequences are extremely severe. When I was at school in the UK if you were caught cheating on an exam you got an automatic failure ("I didn't know it was not allowed" was no excuse) and if the cheating was deemed to be deliberate then ALL your exams taken at that time were automatically failed on the basis that if you cheated on one you may well have been cheating on all. Believe me not many people cheated in those circumstances and everyone made sure they knew exactly what the rules were.

    The problem today is that you cannot do that because parents and possibly lawyers get involved and the law then requires "appropriate punishment" given the exact actions and does not allow for severe punishments designed to set an example to others. The result is that, rather than being able to catch some fraction of cheats and throwing the book at them to discourage others, we end up having to catch almost every incidence of cheating which is not compatible with trusting the students. This of course perpetuates the problem since people who are strictly monitored for compliance are far more likely to comply to the degree that they are checked on whereas if you trust people to follow the rules they are far more likely to comply and will usually feel happier about doing so (as long as there is some chance they may get caught for violations!). Schools have it even worse since they have to deal with parents fighting the school when they try to punish pupils for cheating.

    Today in a typical course of ~250 students I will usually have to report at least one for cheating every year, about twice the rate it was 5 years ago (rough estimate with admittedly low statistics). The result of this sea change in attitude is that we have increasing numbers of students entering university who are used to a culture of cheating and these need to be caught early and given an education in acceptable, ethical behaviour. So until society decides to start properly supporting teachers who discipline pupils in school and allow for severe punishments (in cases of clear guilt) this situation is likely to get worse, not better.

    My philosophy...is that the concepts and ideas of physics are represented by the math, but not defined by them.

    Correct - maths is the language of physics and just like any language it is used to express ideas and concepts. As such you can certainly, albeit it crudely, explain the concepts in other languages such as English which lack the precision of maths, in much the same way that you lose a lot of the beauty and depth of Shakespeare if the bard is translated into, say, French. Similarly you are fooling yourself, and more importantly your readers, if you think you have communicated those concepts at the graduate level: that requires maths for a full and deep understanding of the ideas involved which is why certain topics are regarded as 'graduate level'.

    I might as well say that I've covered graduate level physics concepts after giving an ATLAS outreach talk since Higgs, Supersymmetry etc are all topics covered in grad school. However it would be a pretty horrendous outreach talk if I covered those concepts in the same level as I would when teaching a grad course so it would be wrong and misleading to claim that I'd covered graduate level topics.

It is certainly possible to teach the basic concepts but if you think you are learning "graduate level" physics you clearly have no idea what graduate level physics is because that requires maths in order to communicate a full understanding even though the understanding in your head will be in "pictures".

    For example I can simply tell you that in nature every symmetry produces a conserved quantity. You can think about it for a while and perhaps convince yourself that this is true. However without understanding Noether's theorem and basic Lagrangian mechanics your understanding will be far from complete and, worse, you will have no way to be able to calculate what the conserved quantity is given a particular symmetry or vice verse....and this isn't even graduate level, its second year undergrad!

  8. Alchemist's Guide to Making Elements on Price Shocks May Be Coming For Helium Supply · · Score: 3, Informative

    You mean to tell me that Alpha Decay is rare in the universe? I simply don't buy the argument.

    Alpha decay is incredibly rare in the universe. The reason for this is that only heavy elements will decay by alpha particle emission that is elements like Uranium, Thorium etc. All of these are far, far heavier than iron which is important.

    Next question is where do all the elements come from? The very light ones such as hydrogen and helium were formed in the Big Bang and the accurate prediction of the observed abundance's of these gases is one of the major achievements of the Big Bang model (the technical term is Big Bang nucleosynthesis).

    The slightly heavier elements such as carbon, silicon, oxygen etc. can be formed in the heart of any star by nuclear fusion binding nuclei together in complex fusion cycles. However iron-56 is the most stable nucleus possible so once you have bound nuclei together to form this you cannot get any more energy out and, in fact it requires energy to make heavier nuclei.

    So where do all the elements which can undergo alpha decay come from? Well if you have a sufficiently massive start (above 9 solar masses) when it finally turns its core into iron there is no more energy to be had and the entire core collapses under gravity and then rebounds in a super nova explosion. In this explosion there are massive numbers of neutrons produced which stream out through the star's outer atmosphere. This results a very complex chain of neutron capture and decay (which nuclear astrophysicists study at places like TRIUMF) resulting in the heavy elements like Uranium, lead etc. that we find on the earth today - in fact ALL the elements heavier than iron-56 were produced in this manner.

    So to get alpha decay you have to have a radioactive element that was produced in the heart of a particular type of dying star. In terms of the total mass of the universe the about which exists in such a rare and hard to produce form is minuscule. Hence, although alpha decay is common on the Earth is is incredible rare in the Universe.

    How am I then going to pay the bills?

    That is the one good thing which copyright does do - it lets people like you make money from being creative. Unfortunately that good has to be set against the invasion of privacy, loss of fair-use rights, legal bullying, suppression of competition etc. which big businesses also use copyright for. Hence my point that whether copyright in its current form is still a net benefit to society is debatable.

    Abolishing copyright would be an extreme position to take but what about reforming it? For example a copyright term of 10 or 20 years would still let you make money from your program as would codifying fair use rights and making DRM which violates them illegal. Even if copyright were abolished you can still make money - several big corporations make money from Open Source software that, while copyrighted, is free to copy. Even with your current business model perhaps you could make money selling support rather than the program itself?

    I should be clear that my original post was not meant to advocate abolishing copyright. While I am not convinced that, in its current form, it is a net benefit to society it seems to me that the more sensible approach to take is to reform it into something which is.

No you could say that I'm wrong and a majority would not agree with that. However I suspect that IP based industry agree with me that this is the case which is why they employ means (that while legal I suspect a majority would also agree are unethical) to convince politicians that the existing system should stay. This also explains the frantic attempts by the RIAA and others to attempt to persuade people that copying music/films/etc. is morally wrong. If a majority of people agreed that it was there would be no need for this and copyright infringement would be a far smaller issue than it currently is (though of course it would still be there since humans are known to act immorally even by their own definitions!).

    What is needed is a free, open and public debate on copyright without undue influence by media groups. Until then I would expect public resentment to keep growing and laws to keep getting stricter until either innovation and creativity is stiffled by the laws or the resentment results in a backlash that damages the industry to such an extent that innovation and creativity are stifled by lack of money.

    you can not claim that your "moral right" permits your behavior because that area's already legally covered.

    There is a difference between 'legal' and 'moral'. It is certainly possible for something to be moral or ethical but illegal just as it is for something to be legal but immoral or unethical. So it depends what you mean by 'permit'. For example if I had purchased that sheet music my morals would permit me to perform that music in public since I paid for a copy of the music. However the law says that I cannot and so I might refrain in order to avoid paying the associated fines (something for which the public should be very glad of given my musical abilities! ;-).

    Clearly copying the sheet music is illegal, at least in the US, in Canada private copying between individuals like that is permitted and legal (at least that is my understanding).

    I agree exactly - that's why it is best to avoid some of the details and explain the rest. This does leave some gaps and if you have a smart member o the audience or interviewer then they can pick up on that and ask about it. This not only helps you - because now you are talking about something they clearly are interested in and understand at some level - but invariably makes them happy because they know that they have asked a smart question and will be encouraged to ask more!

    ...course concerning the QM of chemistry...I think subjects are too often presented as something mysterious

    It is interesting that you should pick that particular example. One of the complaints that us physicists often have about QM taught by chemists is that they introduce it very early (because they need to use it for just about everything) and so cannot teach it in its proper detail i.e. solving the Hydrogen atom electron orbitals from scratch. Hence you end up with this recipe-based approach without a real understanding of where it all comes from at a fundamental level....which is probably exactly what mathematicians say about us physicists regarding maths! :-)

    why not try something like "Well, we don't know what reality is like at so small a scale, because we can't make measurements that fine"

    Well one reason is because that would be wrong. We do know how reality works on such a fine scale - it simply does not define position and momentum as single quantities (in fact it doesn't do that at any scale - but the difference is too small to see at large scales). An illustration: look really close at your display and you'll see pixels (don't try this on your new iPhone 4 ;-) so clearly your display does not define the position of a point to less that the dimensions of one pixel. The universe is similar - it does not define the position of an object to a fixed point. However unlike the screen the "resolution" is not a fixed value.

A large fraction of the public can generally understand the basic concepts once they are explained without the technical vocabulary and without all the unnecessary details.
