  1. Passed my semester project exam, got an A despite only having 2 hours sleep and being completely braindead and gibbering incoherently

  2. I like most stuff, but my preference is for rock/metal of most genres. I tend to go in phases, had a big rock opera moment recently, where I was into Avantasia etc, I am writing my project at the moment, so busy reading loads of papers, so listening to Vivaldi as I find it helps me think, and then Linkin Park, Metallica and Iron Maiden to let off steam between writing sessions. I also have a thing for really cheesy power ballads, and a bit of an addiction of Alice Cooper "Last Temptation" (This comes under Rock Opera addiction I think) I am a lyrics person, the melody is less important. I do have a thing for Trance for relaxing, which explains my interest in vivaldi apparently My boyfriend told me to listen to Mozart to study, but I never liked him, even when I used to play the piano, so went for Vivaldi, which my boyfriend claims is "Classical Trance or Techno"
  3. Its from April 2007 I think, so just before AR4. I am on a laptop atm, so can't watch it, but will look later. According to the info I could find online (Infowars.com etc), it includes the Willie Soon and Sallie Balinuas interpretation of data which if I remember was the Climate Research journal paper which lead to the resignation of a load of the editors. I will take a look at it later today hopefully, but my initial search of sites where it is recommended does not leave me with a good feeling about its accuracy.
  4. If it is the Christopher monckton documentary, there is a response by John Abraham that is worth watching
  5. Isnt the moon moving away from the Earth?
  6. Usually you have to take very high doses to get toxic effects, any excess is, in the majority of cases, excreted out. For example, it is quite easy here to get vitamin D supplements with many times the recommended dose (30mcg vs the RDA of 5mcg), I get these on prescription once in a while when my levels drop low due to winter, red hair + freckles, and staying indoors due to bad weather The majority of vitamins are water-soluble, and so any excess is removed in urine. Fat soluble vitamins are usually where you would have a risk of toxic effects as these are more easily stored. For the majority of people, there is no need to take multivitamins as it is fairly easy to get your required amounts, even on an "unbalanced" diet. I do take a multivitamin due to my very restricted diet, although my blood tests usually come back fine (with the exception of Vit. D mentioned above), so it is more a peace of mind thing for me, and I suspect for many people. I only do this in winter, as my diet in summer is much higher in fresh fruit and veg content. The levels at which toxic doses occur are also very high compared to daily intake, if you take for example vitamin C, the RDA is 90mg, and the upper limit is 2000mg, some of the B-vitamins have lower ratios if I remember. More common side effects are things like diahorrea, especially from supplements with iron. This link has the upper limits, effects, and cases each year: Vitamin toxicity
  7. It is worth checking this book out: Why does e=mc2, and why do we care Goes into depth with regards to all things Einstein related, including proofs with minimum mathematics, and explains the concepts of matter, speed of light, space-time etc in very easy to get to grips with (without having a patronising tone) terms.
  8. I am not from the US, so unsure how your Majors work over there, but it sounds like Organic or Analytical chemistry would be of interest to you. Check this site out for different types of chemistry and career information: Careers in Chemistry

    Textbooks

    If you have forgotten the basics, Wiley publish some "Teach yourself Calculus" etc books
  10. Thanks! I was looking for that, but couldnt find the site!
  11. The thermodynamic meaning of entropy is a irreversible thermodynamic process. The simplest way to look at what your instructor has asked you is to consider what you are looking at with entropy. When calculating the change in entropy for a system, you are looking only at the initial and final state of a system When you talk about work in a thermodynamic balance equation, what are you describing in regard to the state changes? This link might also help Thermodynamics Entropy wiki Also try this one: Entropy & Thermodynamics Sorry for the obscure answers, but I cannot think of how to explain it better without giving you the answer Hopefully someone else will be able to do it in a simpler way than I have
  12. I have seen all his stuff, along with Nassim Haramein, and most of the others in those schools of thought, my other half is very into those vids and theories.
  13. If I remember, the methane is stored in Methane Clathrates under the ocean floor, these are very unstable, and sensitive to temperature and pressure. One of the issues with extracting these methane resources is that once they are brought up to a warmer temperature with lower pressure, the gas has a tendency to expand rapidly. In the confined space of a pipe, this is potentially explosive (There are videos out and about showing this). The methane clathrates stored under the ocean floor are one of the uncertainties in climate feedback. The temperature at which these clathrates become unstable is still unknown, and the quantity is also an unknown. Largely it exists in a region known as the Gas Hydrate Stability Zone. This is sediment where the temperature is cold enough to keep the methane within the clathrate structure. This zone is relatively shallow, in that it only extends a few hundred meters below the ocean floor. Along with the bermuda triangle, Methane is also suspected as the cause of ocean floor collapses, including one off the coast of Norway several millenia ago.
  14. Thanks! That was just what I was looking for, just couldnt get the search term correct.
  15. Hopefully this is a fairly straightforward question: I am currently writing on Solar radiative output, and have run into a term several times that I cannot find a definition for, "Centre-to-limb radiance variation" f (μ, λ) If talking about total solar irradiance as measured by a radiometer, I am figuring the centre is the centre of the Sun, however, I cannot find an answer as to whether the limb is referring to the range of the radiometer from the centre, or whether it is referring to the centre to edge of disc radiance variation in the direction of the radiometer. Any help is muchly appreciated as those 5 words are driving me crazy at the moment!
