    Eternal restart. Buddha was right !
    Now, compare with the previous thread, taking the "Vs" off and replace it by "and" seems to bring more peace, longevity and serenity in the talks.
    Opposition is less productive than association
    This is a good thing to remember.

    Egg and chicken ;-)

    Dreams too, certainly help to have the energy to make it



    Yes you are right. Sorry for the confusion.

    The way we copy the life in science is a good example of this.
    Shark skin for skin effect to stay on a subject of today.

    Are you saying that flow math was discovered in the absence of empirical evidence?

    Or that a hundred plus years of wind testing and tank testing were merely devised to entertain the folks working in that industry?

    I think wooden ships evolved for centuries without a shred of flow algebra being applied.

    Applied math is physics. That is a completely different thing. For example, in math there is a single one. That is the concept of unity and there can't be more than one. In applied math, there are number ones all over the place. The casual use of the name "math" makes it confusing.

    Maybe we should try to narrow this discussion so we can understand what you are saying.

    I know as a young person, I imagined parabolas prior to learning the algebra to define them.

    After I learned algebra I could see them more clearly and was able to define how I watched (in my imagination) the curve bend over distance and time.

    Wikipedia is OK but it can be anyone posting whatever. I am saying that Math and applied mathematics are very differenent. Mathematics deal in abstractions and applied mathematics deal in "good enough accuracy to make it work" They are very different from each other. I think we were discussing about different things.

    And then I learned AutoCAD and now I can apply them to designs with a high degree of accuracy. But I know thousands of people that could never do that if you sent them to school for the rest of their lives.

    Even if they could learn the "math".

    So, are you saying that boats could be completely designed by an algorithm?

    Nowadays they are designed with computer programs. A batten is a variable curve that can be described by an algorithm.

    A man walk on a road on a sunny day.

    He meets another guy braking stones on the side of the road.
    Hello, how are you ?
    The other answers: Bad, i break stones under the sun.


    Then meets another one braking stones on the side of the road.
    Hello, what's up ?
    The other answers a little upset: Idiot ! Bad, i break stones and it's fu...g hot and hard !


    The man hits the road again.
    Hazard supreme, on the same road, once again meets a third guy braking stones with a big smile on it's face.
    This time our man carefully ask the stone breaker: Hello ! Isn't it too hard to break stones under the sun ?

    Braking stones ? answers the other very surprised.
    I am not breaking stones boy.
    I am building a cathedral !



    Dream are important as without dreams, the energy of intuition and physics get out of fuel on day or another.
    Out of fuel...An old history in fact ;-)



    Please note that by cathedral you should understand a spiritual goal in general, not necessarily a religious goal.

    If any doubt look at the life of a genius like Copernicus...
    http://en.wikipedia.org/wiki/Nicolaus_Copernicus

    He has had to wait, to be dead, to publish his work

    I agree Gonzo,
    We are seeing a revolution in the capacity for mathmatical machines to create new and previously unimagined entitiies. Look at Avatar (3D Imax) and you will witness the beginning of a whole new art form.

    But without creativity, even simple things like yachts will lack, as Kristinie says, Spirit.

    It's fun to have an argument with someone nice enough not to make it personal.

    Imagine the script of Avatar without 3D and computer, like the one done in the 60's.
    It still would have been a good film. Like 2001 was.

    Now imagine 3D and computer work in a stupid flat heartless story.
    It is a long nice but boring **** soon forgotten.

    I design with pencil. The smell of cedar and paper helps me think. I don't know if it has any effect on intuiton but makes me happy.
