  1. What is true for most verterbrates is that in low light situations animals with rods and cones will see in a gray scale and colour will be diminished. Rods are more sensative than cones as ther are activated by all spectrums of light.
  2. Here is a lot of information from http://www.cs.rit.edu/~rsg/FishVisionSystemGroup2.ppt

    Welsh tope

    There are some welsh boys on the kayak fishing forum that will be able to help you. Ask on there, Yes they catch Tope on plastic cannoes! mad or what.
  4. Hi Yak Attack, We have a Malibu two XL, we found that the Malibu two XL comes with the two seats included in the price, so it workls out cheaper than the Malibu two. Also the added lenght makes quiet a difference to its speed we found ours faster than the Malibu two. It also means three can be carried easier. Me the wife and son number two regularly paddle a six mile trip along the coast quiet easily, only me and the wife paddling and most of the time only me paddling. The storage well at the back on the Malibu and Malibu two xl is vertually useless unless you purpose build some contraption to fit it. The best thing is its versatility, you can move the seat to the centre position and paddle solo no problems, It is a large vessel to paddle alone but you can even get up and streach your legs if you want.
  5. Is the UK still allowing the free trade of birds with other contries? if so why would they? No one can stop the birds returning to the UK in the summer? oh dear.
  6. Alcohol kills by dehydration and is most effective against Bacterial cells. 70% being a better quicker sterilizer than 100%. There are specific antiviral decontamination solutions these may be a better idea to protect from the flew virus. ???
  7. Very interesting, I caught the end of a documentary on the 1918 pandemic which determined that this virus which attacked the fit and healthly more than the old or young did so due to the nature by which it causes death, which is to cause the bodies own immune system to attack any cell within the body which becomes labelled with the virus protein marker. Hence the fittest people with the best immune system are those at most risk. However the very young and old whom may die from a normal case of flu would also be at risk from this flew as well. All in all a nasty piece of work. The USA belive the next bird flew to be aquiring the same genetic mutations as the 1918 pandemic and are therefore stock pilling antiviral drugs to give to the healthy to stop the spread of the virus rarther than cure the sick, the best defence is protect the healthy. These drugs do not provide a long term protection to a patient but rarther act to mop up the virus in the body stopping it spreading. Hence it must be taken during or before risk of infection or during the very early stages of infection. Does any one know if the UK government is stock pilling these antiviral drugs in the same way?
  8. I have enquired from local suppliers and no one has a C-Tug for sale, I have enquired fron New Zealand and the shipping would be about GBP40.00 for a single C-Tug + cost GBP60 + Tax. Does any one know when they are likely to be availible in the UK?
  9. How about a towable kayak Cart http://www.paddlecart.com/ http://www.paddlecart.com/biketrailer.htm
  10. http://www.hookedonkayaking.co.nz/otheraccess.htm The spec here looks impressive, trying to find a supplier in the UK
  11. I am looking forward to trying them at easter which is the first time I'll have a free weekend but promise to report when I get out.
  12. The C Tug Looks Ideal Where from and How much? any info appreciated
  13. Our site does not open till April,, No fair.
  14. I think recognise that head land in the distance in your picture is it Llangranog?? Yep bungalows going OK means I wil be staying in the van again this year thou.
  15. woo it is a small world, Thanks for the help.
  16. Does the Big bang Theory offer a perfect explanation without any unanswered questions, or are there any measurable features of our universe that do not comply with the theory?
  17. Leon's unfaltering stance on the non existence of time before the Big Bang has caused me to dig deep into the current theories of the origins of the universe. I admit that the theory does state that time was created at the point of the Big Bang, hence to talk about time existing before is not correct. I have read a lot and understood little, but I can say that many great minds all around the world are restless and are searching for answers, answers to why, how and yes you guessed it what caused the Big Bang? If something caused the Big Bang, then it must have been in existence prior to the Big Bang. It may not have existed in time or space as we know it, but it must have existed. If time started at the point of the Big Bang then it must have existed prior to the Big Bang. You may still have a problem with saying before or prior to the Big Bang as this is a measure of time, and as you have defended this point with such vigour. All I will say is there are a great number of scientists spending a lot of time considering this very concept and I hope you would not dismiss there ponderings as nonsense as you did mine. Best regards
  18. Well done, It is one of the hardest things in the world to do. Be very proud.
  19. I can see why you are sticking to your point so dramatically. If I were to say in the begining God created the Hevans and the Earth, and I say ah yes but what happended before that? you would say no no thats it there is no before you nonsense talker. I will always answer why? How? You are Right I do not take the big bang theory as a complete answer
  20. You seem to think I have it in for the big bang theory, I do not and as you say (for now) this means enough evidence exists to support this theory. Yes the brains are another theory with no evidence. If time was created at the singularity then it is still a fair question to ask what happened before! a total void with no matter and no time and no energy is one theory but please stop telling me I cant ask the question and by doing so am talking nonsense. I am only taliking nonsense by the confines of a theory which I choose to question.
  21. "About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What exisisted prior to this event is completely unknown and is a matter of pure speculation." "According to the standard theory, our universe sprang into existence as "singularity" around 13.7 billion years ago. What is a "singularity" and where does it come from? Well, to be honest, we don't know for sure. Singularities are zones which defy our current understanding of physics. They are thought to exist at the core of "black holes." Black holes are areas of intense gravitational pressure. The pressure is thought to be so intense that finite matter is actually squished into infinite density (a mathematical concept which truly boggles the mind). These zones of infinite density are called "singularities." Our universe is thought to have begun as an infinitesimally small, infinitely hot, infinitely dense, something - a singularity. Where did it come from? We don't know. Why did it appear? We don't know. " "In physical cosmology, the Big Bang is the scientific theory that the Universe emerged from an enormously dense and hot state about 13.7 billion years ago. The Big Bang is a consequence of the observed Hubble's law velocities of distant galaxies that when taken together with the cosmological principle imply that space is expanding according to the Friedmann-Lemaître model of general relativity. Extrapolated into the past, these observations show that the Universe has expanded from a primeval state, in which all the matter and energy in the Universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity. "The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the Universe (Hubble's law) began—calculated to be 13.7 billion (1.37 × 1010) years ago—and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the Universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory." " 'Brane-Storm' Challenges Part of Big Bang Theory By Robert Roy Britt Senior Science Writer posted: 02:33 pm ET 18 April 2001 Faster than you can say "Ekpyrotic Universe," a movement has taken hold -- albeit like fingers on a ledge of eternal skepticism -- that would blow one of the basic tenets of the Big Bang to smithereens. Think parallel branes and five dimensions. Science never sounded so cool. The new idea would not replace the Big Bang, which has for more than 50 years dominated cosmologists' thinking over how the universe began and evolved. But instead of a universe springing forth in a violent instant from an infinitely small point of infinite density, the new view argues that our universe was created when two parallel "membranes" collided cataclysmically after evolving slowly in five-dimensional space over an exceedingly long period of time. These membranes, or "branes" as theorists call them, would have floated like sheets of paper through a fifth dimension that even scientists admit they find hard to picture intuitively. (Our conventional view of 3-D physical space, along with time, make up the four known dimensions.) " Common to the quotes is we do not know what happended before, and the last is a theory that postulates an alternative to the singularity. We do not know but we try to explain what we can measure thats all we have.
