    oh its glen beck....   <- back = Figuratively sticks head in sand.

    Im not a fan of Glen Beck. Im not a fan of Stephen Colbert. nether of those video clips had any kind of use full information.

  • I went back to Internet Explorer from Firefox

    Never! I have grown so far away from IE in the last couple years I can't see myself going back. I also enjoy my FF addons too much to go back (adBlock,Firebug, noscript). When IE is killed (thought I read that IE8 is the end) and the next MS thing comes out I'll switch. The only time I open up IE is when I am working with an enterprisey app.

    I have both FF and IE8 installed. I use both but tend to lean toward IE 90% of the time. But harumscarum you just keep on using FF and wearing your tin foil hat. =)

    "To be clear, light is NEITHER particle or wave, but a wave particle duality. It only becomes one or the other when we look at it, and which depends on how we look at it."

    Light is both a particle and a wave? I’m confused.

    The photon is not the medium like air is to sound, it's the force carrier for the electromatic force.  Every time an electron transitions to a lower energy state, it emits a quanta of enery, a photon.  Therefore you could not remove the medium light travels in, you'd have to remove light it's self at which point the universe falls apart Smiley
    If there was no light in the universe, why would it fall apart?

  • Non-Photon Space, possible?

    If one gets rid of the friction caused by air it is much easier to go faster than the speed of sound? And your reasoning is, if you get rid of photons/light you will be able to travel faster than light. Well I’m not sure if that is how it works. but i like that your thinking.  you might try your questioning at this other forum. http://www.physicsforums.com/

    For me is not much difference. LA is always Sunny. We already have a lot of people playing on beach vollayball and beach football last week.
    Did you say LA is always sunny or Smoggy? because I have been to LA and all I remember was this dark brown cloud above it.  =)

    Um, I've studied my fair share of chemistry so I know that already. I was just confused about magicalclick's assessment of consciousness being related to waves.

    Sorry tfraser, Its magicalclick’s idea that waves make every thing I had hoped to debunk.

    Huh?

    Every thing is made up of atoms. With in the atom is a nucleus made of protons and neutrons. Around the nucleus are electrons. The protons and neutrons are made up of things called quarks. Atoms and their formation constitute elements that we see on the periodic table. The elements form to make molecules. In organic chemistry these molecules then make up things like proteins, DNA and RNA.

    Thanks Dr Herbie for your insight. It's just in the last few years have I realized how great learning is. I have a collage text book I have been reading to learn more about DNA.

    DNA doesn't "work" to do anything. DNA is just a chemical molecule.

    DNA codes for proteins (or rather, more like a hdd drive, it just stores in the information needed to make those proteins). The DNA is then "read" by enzyme (just specialised proteins) that stick amino acids (organic chemicals with an amino group (NH2) on one end and a carboxylate group on the other (COOH)) together to form other chemicals.

    DNA isn't perfect and so, at some point, the information doesn't get copied correctly (a mutation, it gets corrupted) and the proteins aren't made right. These changes to proteins will cause some kind of change in the organism, sometimes this is beneficial (e.g.. disease resistance) and sometimes not (e.g. cystic fibrosis) and, more often than not, both (e.g. sickle cell anaemia mutation provides resistance to malaria). Based on the pressures around at the time (e.g. is malaria a problem in your part of the world?) that mutation will either increase your chance of surviving (malarial areas) or decrease it (malaria free areas).

    If there is reproductive isolation (behavioural/geographic) between two populations of the same species then, over time, these changes will lead to a level of difference where they cannot reproduce with each other to form fertile offspring. At this point we describe it as a new species (arbitrary marker really).

    The guys I would put money on cracking it are http://genomicsgtl.energy.gov/ (that site'll probably answer most of the rest of your questions).

    And while I'm at it may I recommend the US Governement Department of Energy's excellent free poster (http://public.ornl.gov/hgmis/external/poster_request.cfm) (although delivery takes a while it was definately worth it just for my mother to ask me why I'd got a large envelope marked "US Government" through the post Tongue Out).

    Hope that answers your questions in an understandable way Smiley



    People living with sickle cell anemia are resilient to malaria, this allowing more of the sickle cell gene to be passed on. But sickle cell anemia causes a lower life expectancy.  This is something new I learned from c9. 

    In the video above in the last demonstration it shows hemoglobin sticking together and becoming an elongated cell? But before it does so. Little blue things attach to the hemoglobin and then a little green thing pops out. What’s going on here?

    its also just amazing to think that we have little machines in us reading code.
