  1. Cool. I'd love to learn more about this, and I'm kind of torn I didn't pick physics as my course to do at University. I'm not interested in a career being a physicist, but I'd love to learn much more about this in detail...
  2. Too true. Note this is as long as you lick your own wounds and not somebody else's! Otherwise you're probably helping spread germs[i know its fairly obvious].
  3. You could place some kind of container on a mass balance and evacuate the air using a vacuum cleaner or something like it to create a vacuum. if there are no leaks in your container; then when you zero your mass balance it should read zero[you'll have to figure out how to do this, perhaps you could use a remote controlled signal]. If you now allow air into your container you should immediately get a reading. The fact you have been able to measure its mass shows the force of gravity is acting on it and it therefore has a weight[really your only measuring its weight]. Hope this helped you.
  4. I read a similiar article in the independent[i think, it's been a while since I read it] by a woman who was investigating why women tend to have lower wages than men, and perhaps have slower career advancement. The author highlighted an alternative reason for this and it was that was that women may be less assertive than men, for example at interviews, overall men tended to be more willing to negotiate a higher salary than women. This would result each year, as they progress through their career and the salaries increase by a fixed percentage[for example] the difference overall in average salries of the men and women surveyed would increase. I know that the subject matter of why not as many women do PHDs is different, I just want to point out that the reasons for the disparities and differences between men and women in the workplace maybe more complex or subtle, than a simple case of how each is brought up, or any perceived genetic predispositions. I do also agree with you that the lifestyles of men and women are still pretty different overall, and even though things are changing and there are phenomenon now like stay-at-home-dads.
  5. Hi everybody. The thought just recently hit me and I'm sure there is probably a good explanation for this phenomena, but why; when photons are massless particles, do they get sucked into black holes with their strong gravitational field? Is there something fundamaental here which I have not considered?
  6. Thanks a lot for the feedback Martin, I'm grateful for it. To be fair with you I didn't try to find out that much about McFadden, though I diod have a brief look at the links at the surrey university site you just posted earlier. Also on a more personal point; I was pleasantly surprised that Jim Al-Khalili, the author of Quantum a guide for the perplexed, a book I recently purchased:-) . I've only read about a third of the book but I do remember when I was arbitrarily flicking through the pages at the store that it had some pages related to quantum phenomenon in biology and even a short section titled Quantum neurodynamics. I will elaborate more on what he talks about in these sections later, however another researcher and his research group people should have a look at is Dr. Peter Gariaev. I know that he was an invited guest speaker to give a lecture on the Anticipatory Quantum Biosphere Learning from Nature and I found this out on the British computer society website which mentions the lectures were in 2001. The address where I found this was: http://www.bcs.org.uk/siggroup/cyber/casys2001.htm I also urge anyone reading this to have a look at the following papers I have already made links to in this thread, as well as one that I haven't, and tell me what they think of the physics involved. Is it sound? http://www.emergentmind.org/gariaevI2.htm http://www.emergentmind.org/gariaevI3.htm http://www.rialian.com/rnboyd/dna-wave.doc
  7. I see the logic in your explanation, and from your reference to hypermutation it may be a fair explanation for this pheneomenon if certain genes are can mutate very readily to adapt to a change in enviroment. It just doesn't seem to make sense to me that this kind of beneficial mutation, which should be highly unlikely; occurs at such a fast rate to produce the entire gene to code for a very specific protein namely lactose.
  8. thanks a lot everybody you've helped clarify things.
  9. Hi everybody. I was just wondering do all photons and neutrinos really have zero mass or is this just to make equations work? It just confused me because my physics teacher told me that photons have zero mass, and this allows them to travel at the speed of light without becoming infinitely heavy; yet i know that photons do have a momentum, so it would seem that them having zero mass would be impossible. Can anyone help me resolve this? Thanks in advance. P.S. if anyone has a good knowledge of quantum physics, please could you have a look at the Quantum evolution thread I've posted in the physics forum. I'd just like to know what you think.
  10. sorry that was a stupid question[i mean mine] I've just looked at the article on Wikepedia about Anti-hydrogen. Seen as were discussing anti elements and antimatter, I'd just like to know what are tachyons[i'm not making this up I promise!], and why do they travel faster than the speed of light?
  11. Have experiments beeen carried out, investigating how antielements interact with elements?
  12. Forgive me if this sounds really stupid, I don't think it could actually work, but: Could anti-elements make up a bit of the predicted dark matter in the universe, and interact so rarely with ordinary atoms and molecules rarely because of their overall neutrality[in terms of having no overall charge for example? The reason I thought of this is because I thought there may be a parralel relationship between the way positrons interact so rarely with matter; that particles like electrons would also interact very rarely with anti-elements[if they existed]. The other reason why I'm proposing this is that I thought that its no surprise we don't find many fundamental antimatter particles, as we don't find many lone neutrons, protons or electrons[apart from radiation where we also find antimatter particles like the positron in beta decay] existing on their own either as they exist predominantly in atoms and molecules. P.S. could someone please have a look at my Quantum evolution post in the Physics section:embarass:
  13. I have already posted this in other threads in the biology section of these forums but didn't get many responses. This is why I'm posting it here as I assume people reading it may know a lot more about how these processes could work[and won't be scared off by the word Quantum] [To be honest I'm no Quantum physics expert by any stretch of the imagination, which is why I would be very grateful to know peolpe's opinion on this]. Basically I'm proposing that evolution as we know it is not caused by so called random occurences, but is caused directly by organisms gaining information about their enviroment and adapting because of it. For example from the website: http://www.surrey.ac.uk/qe/Outline.htm I got the information that: "If these particles can enter quantum states then DNA may be able to slip into the quantum multiverse and sample multiple mutations simultaneously. But what makes it drop out of the quantum world? Most physicists agree that systems enter quantum states when they become isolated from their environment and pop out of the multiverse when they exchange significant amounts of energy with their environment, an interaction that is termed ‘quantum measurement’. Cells may enter quantum states when they are unable to divide and replicate – perhaps they can’t utilise a particular substrate in their environment. They may collapse out of those quantum states when their DNA superposition includes a mutation that allows them to grow and replicate once more. In this way the environment interacts with, and performs a quantum measurement on the cell, to precipitate advantageous mutations. From our viewpoint, inhabiting only one universe, the cell appears to ‘choose’ certain mutations. But is there any evidence for this? When John Cairns of the Harvard School of Public Health in Boston set out to test the dogma that mutations occur at the same rate whether or not they provided an advantage, he found that things were not so simple. Cairns examined bacteria that were deficient in their ability to utilise the milk sugar lactose. When he exposed these bacteria to conditions in which lactose was the only food source, they starved. The cells did not die but instead went into a kind of suspended animation state, called dormancy. Dormancy was a well-known phenomenon so Cairns was not surprised to find that his bacteria managed to survive in this state for many weeks. What did come as a surprise was the discovery that, after a lag period of a day or two, several of his bacterial cells managed to grow and replicate. These replicating cells had acquired a mutation that allowed them to feed on the lactose. What was even more surprising was his observation that the cells only acquired these lactose-eating mutations when lactose was available" The way these organisms find out about their surroundings has a lot to do with how the macromolecular world interacts with the quantum world and this involves quantum entanglement. There are also 2 website addresses showing work by russian researchers on precisely how this works. I didn't understand a lot of the jargon used but I'm sure there are people who will. http://www.emergentmind.org/gariaevI2.htm http://www.emergentmind.org/gariaevI3.htm
  14. Hi everybody I've begun studying entropy at college and something is bugging me. I know that for any reaction: DeltaG=DeltaH-TDeltaS and for a reaction to be feasible the change in "free energy" or G has to be negative. Does this apply for photosynthesis too? As far as I am aware it would be endothermic, producing a positive deltaH value and it produces glucose and oxygen[gas and solid] from water and carbon dioxide[gas and liquid]. This would cause a drop in entropy, therefore making the reaction impossible. Have I missed something critical? Please help me resolve this!
  15. I think that our mapping of the genome hasn't been a holy grail at all and what proteins that our genes code for is only a tiny part of the story, in terms of how our biological mechanisms function in real times. I think personally we have been concentrating far too many resources on the 5% or so of our genome that actually codes for stuff. We have ignored the 95% junk dna which we seem to have more of than any other organism and its purpose. From the information I know now, I firmly believe this is used in hypercommunication between living cells and organisms. I may not be able to argue my point too well about this as I feel I do not know about this area enough, however I will give you a few websites where I gained a lot of information that made me think; hmm there's more to this than I thought. If there's any physicists reading this, I urge you to have a look at this as the way the information is transferred is by something to do with quantum entanglement. Listed below are papers written by a russian research team that looked into this, as well as a few introductory sites. http://www.surrey.ac.uk/qe/Outline.htm http://www.nanoword.net/library/weekly/aa062500a.htm http://www.emergentmind.org/gariaevI3.htm http://www.emergentmind.org/gariaevI2.htm
  16. I don't think I've fully explained to anyone why I think you should all have a look at this russian research I have mentioned. The reasons I was reluctant was that I feel I do not have enough knowledge of this to do it justice, and for fear of criticism. Basically I think they have found how another, completely different aspect of DNA, RNA and protein molecules affects living processes. This is that the DNA as a whole utilises the EM waves of light we are constantly exposed to; in order to communicate with other cells and organs of an organism. This communication is carried out by a method known as quantum teleportation[something to do with quantum entanglement]. This probably asounds like pseudo science, which is why I urge anyone to have a good look at this and tell me what you think much experimental work has also been carried out by them; and they have reached conclusions on the basis of this. To give you my frank opinion I think the implications of this are quite profound, and how much quantum principles apply in biology has long been underestimated. I'll list the websites I previously posted and a few more for anyone interested;) . http://www.emergentmind.org/gariaevI2.htm http://www.emergentmind.org/gariaevI3.htm http://www.surrey.ac.uk/qe/Outline.htm http://www.rialian.com/rnboyd/dna-wave.doc http://www.nwbotanicals.org/oak/newphysics/bioholography_a.htm http://www.nwbotanicals.org/oak/newphysics/Helix%20to%20Hologram.pdf
  17. Hi everybody:D ! There is still an ongoing debate in America between intelligent design and darwinian evolution. I think people supporting intelligent design fail to observe how life does not follow a preset plan[and why should it?] but adapts according to its enviroment. I know there are many other flaws in this theory, such as the fact it cannot be tested. However because it has such a poor opposing theory, I don't think many people are paying enough attention to the flaws in Darwinian evolution. I am referring specifically to the random nature of mutations. I have begun to start doubting this is true. I think I've gone on for too long already but I'd like to quote some sites where I received the information to support my current understanding of this[sorry if it's highly flawed I'm no expert on this]. http://www.surrey.ac.uk/qe/Outline.htm Introduces the argument and has links to other sites. http://www.emergentmind.org/gariaevI2.htm http://www.emergentmind.org/gariaevI3.htm These are research papers written by Russian scientists investigating the behaviour and purpose of the junk DNA. You can also find out much more on this by typing "Gariaev" on google.
