    Looking for advice on a new P&S camera

    It's been a long time since I upgraded my camera (my current one still takes floppy disks!) and I'm looking for a little advice. I've read a few reviews including 996GT2's and really like the look of the Fuji F100fd. My question here is, are there any other cameras you guys like that you think...

    2 perfect spheres, same diameter, same weight...one aluminum, one steel. How can you tell them apart?

    It's an interesting point to make. Weight and mass are not the same, even though we commonly assume they are. Your linked example is specifically referring to weight (net force of gravitational pull and buoyancy acting on an object of a given mass), but the original question specifically noted...

    Newbie to DVD-video needs advice

    That's my best guess at this point to, but, unfortunately, the software that comes with Windows Vista gives you no options at all on how it is encoded or burned. The only info I could find in the help file is that it is burning a DVD-video disc and the audio encoding is Dolby Digital Recording...

    Newbie to DVD-video needs advice

    Thanks for the referral, I will definitely try out video help. As for media type, I know that they require DVD-R, but I've think I've ruled out media as the problem by trying a DVD-R off of the same spindle they are already using to burn there copies of their own VHS tapes.

    Newbie to DVD-video needs advice

    Hey guys, I'm brand new to digital video and was hoping to get some advice on a few things. First, a short description of what I have: -A digital video camera that records to miniDV and has USB2.0 output. -A relatively new computer with Windows Vista -Windows Movie Maker and DVD Maker...

    Mothers in Haiti are having to choose which child lives or dies

    For that, you should probably check out the debate thread. It looks like a pretty good approach to me. I usually try to keep two things in mind when evaluating a charity; first is the approach and second is the amount of money that goes to direct aid. For charities that have profiles at BBB...

    How can silver powder be made both conductive and non-conductive?

    Definitely a matter of concentration. I did a quick web search and found a few MSDSs that list the major components of conductive silver paints: http://www.hkwdirect.net/acata...m/datasheets/23711.pdf http://www.farnell.com/datasheets/23711.pdf While the MSDS doesn't have to disclose all...

    Question about SETI

    A slight omission from your logic is that we will also advance during those 1000 years. So actually, the only difference is that they will be about 70 years advanced from the original transmission we get from them (if it only took that long for the signal to get here) and then both...

    Obama's 95% Illusion

    I don't know about taxpolicycenter, but I think most of the numbers come from campaign websites, although they are not always easy to find. I haven't had as much time for research as I like, but I did find this little gem a while back that not only gives a detailed, non-partisan summary of both...

    Actually, this is not true. As Rainsford alluded; be careful where you get your information. If you're interested in candidates proposed tax policies, here is a good link: http://www.taxpolicycenter.org...tion_issues_matrix.cfm In fact, in addition to all those credits you mention, Obama...

    Question about SETI

    I don't know of any continuously transmitted messages, but we have sent several messages to specific stars with the intent of communication. Check out this link for more info. http://en.wikipedia.org/wiki/Active_SETI I find it especially interesting to see how the scientists choose to...

    how to build massive starships in the future...

    Something tells me that will never happen. What kind of structural integrity can you really expect from a massive piece of rock, not to mention all that extra mass that has to be propelled by the engines. I think the general approach of modular design and assembly will persist. What will...

    Would telepathy be bound by the speed of light?

    Wait, let me see if I understand you correctly. You know the truth, but you can't say it in public? ... Priceless. An excellent way to end an argument. :)

    It seems subjectivity is incoherent... attack this argument!

    LOL, I must admit I completely agree. Unfortunately, I'm one of those types that has trouble letting go of a good argument. I just get sucked in. Its a good thing I can still manage to get some work done between posts! I recently discovered a forum for flat-earthers and was appalled at the...

    It seems subjectivity is incoherent... attack this argument!

    I'm glad you've identified my problem :P To be honest, I don't see how existence = truth. Maybe I just don't see things the way you do. I can make a statement like "this rock exists" and if the rock exists then the statement is true. If the rock does not exist then the statement is not true...

    It seems subjectivity is incoherent... attack this argument!

    I'm not trying to argue that objective stuff can be remolded into subjective stuff. Please let me know if one of my statements led you to believe that, and if so, which one. What I've been arguing is that the definition of "real" that is intended to be used for the concepts of subjective and...

    It seems subjectivity is incoherent... attack this argument!

    Well, I wouldn't waste your time on an animation since I don't think the concept of inheritance is even at debate here, at least as discussed between you and I. I don't see how I'm ignoring the concept of inheritance. I have no problems agreeing that everything, by definition is something, and...

    It seems subjectivity is incoherent... attack this argument!

    I must admit that this statement makes no sense to me (emphasis added). Perhaps you can clarify. This seems directly related to the paradox I stated earlier. If the fact that a thought exists somehow makes the thoughts subject matter exist, then there could be no concept of nothing, because...

    It seems subjectivity is incoherent... attack this argument!

    No, I think you are the one misunderstanding. I have no problem with admitting that reality, as you are currently defining it means that everything, including all forms of matter and energy, are connected, related, and ultimately derived from the same real universe. You keep trying to argue...

    It seems subjectivity is incoherent... attack this argument!

    You are confusing "hot" with "heat". The two are not the same and this completely invalidates your comments. Heat, or lack thereof, is the thing you feel. Hot is a relative term used to quantify the amount of heat perceived. The fact that it is relative to the observer is what makes the term...

    It seems subjectivity is incoherent... attack this argument!

    I'm thinking along the same lines. I don't think the terms subjective and objective are quite as concrete they would need to be for the argument xts3 is making. I did a little thinking about it and my conclusion is similar to TuxDave's in that a thought/statement becomes objective when the...

    It?s another bad day for Einstein!

    That's an interesting analogy, but I think it breaks down a bit when you start ramping up the speeds. Both of these analogies require a propagation of force along the entire length of the system. In every day life, this propagation can appear instantaneous because it is traveling so fast, but...

    It?s another bad day for Einstein!

    I think it should be possible to split them, they just won't be identical (to not violate the cloning rule). For instance, when two photons are split, they have opposite polarization states. Now what happens through multiple splits I have no clue about.

    Does "black" really save electricity?

    Makes sense it wouldn't effect LCD screens very much. You basically have a backlight that is always on full power and liquid crystals that change orientation to selectively block the light. I would guess that most of the power goes to the backlight.

    Would telepathy be bound by the speed of light?

    I'm a little confused by this scenario. First, I think you have your distances mixed up. The Earth is ~8.3 light-minutes from the Sun, but only 1.2 light-seconds from the moon (surface to surface). Second, how could the "viewer" tell there was or was not a time delay between what they saw and...

    Why is the speed of light our "speed limit"?

    I think sometimes in scientific math we get nice round numbers because the things we are comparing are inherently related. In this case, I'm not really sure. It looks like the meter was originally based on a conveniently chosen fraction of the earths circumference. Even though it has been...

    Why is the speed of light our "speed limit"?

    I think this brings us back to the question I previously asked. How do you prove a fundamental limit? As I understand it, we have a theory which has been tested by a multitude of experiments covering speeds ranging from 0 to 0.99c and it has held true over the entire range tested. This...

    Reducing outgassing in computer components

    I would agree. There are a lot of things that can be done, but won't if there is not a financial or legal incentive. For manufacturers to address this issue of outgassing would take one of two scenarios in my mind. First, research begins to show evidence that the levels of chemicals being...

    Question about the speed of light barrier

    That's an excellent piece of info I wasn't aware of. Thanks for sharing. I had a feeling things like time dilation and length contraction somehow made up the difference. I think you have to see how all these pieces fit together to see the consistency with our observations. I also agree...

    Would telepathy be bound by the speed of light?

    I've heard of the shared feelings like this before, but I've never seen any rigorous proof of it (if you can link any reputable examples, I would love to see them). But if we assume, hypothetically, that it does exist, I think you would need to approach the problem from one of a couple...

    Question about the speed of light barrier

    I would love to understand this better as well. I've read a bit about it and understand what the basic effects are, but not so much why. To answer your first question, there is no position of absolute rest. Einstein's Special Theory of Relativity was specifically intended to make this...

    Why is the speed of light our "speed limit"?

    Actually, there is plenty of experimental evidence that supports Relativity theory. I'm no expert, but you can do a little digging starting with wikipedia if you're curious. http://en.wikipedia.org/wiki/S..._of_special_relativity http://en.wikipedia.org/wiki/T..._of_general_relativity...

    How would nanotech work for practical applications

    There are a lot of insteresting ideas like this one, but I agree with QuixoticOne that much of this technology is already around without the need of nanomachines. There's something fascinating about imagining a nanoscale miniature version of a machine performing tasks for us, but in reality...

    How would nanotech work for practical applications

    Keep in mind that what makes "nano" stuff so special is that it operates in a completely different level than we do. This gives them some fantastic abilities, but also limits them in some ways. Asking a nanomachine to transport itself over distances of meters while mining on an asteroid is...

    Reducing outgassing in computer components

    That would depend on what diffusion you're trying to prevent. I think there are plenty of ways to block diffusion of small molecules without significantly affecting heat transfer. And actually, I don't believe that most components in a computer producing significant amounts of heat are the...

    Reducing outgassing in computer components

    You've got the right idea, but it is probably not a significant factor in this case since the outgassing (evaporation) is very slow on the timescale of months and years. You can think of it as a concentration gradient. There is some of the volatile (able to evaporate) compound on the surface...

    Reducing outgassing in computer components

    I agree with Cogman. The outgassing is occuring frmo the materials regardless of the fans. It would diffuse out of the case even if there were no fan at all. The only way to reduce outgassing, I believe, is to prevent it at the source of manufacture, as I think you were getting to with all...
