Heart Surgeon Takes Notes from da Vinci

vivekg writes "Leonardo da Vinci probably never thought he had the proverbial Holy Grail to a revolution in heart surgery. Almost 500 years after da Vinci's death, intricate diagrams of the human heart made by him have inspired a British surgeon to pioneer a new way to repair damaged hearts."

    Old science is not necessarily bad science. In fact, the hallmark of good science is how well is holds up over time and continued testing. Granted, Leonardo de Vinci was not "practicing" modern science. Rather, he was using the oldest form of science which is observational science. However, this approach is still valid and tends to be the most robust type of science which, like Leonardo discovered can also lead to the most controversial reactions from people who have investments in the current understanding of certain topics........... *cough* *cough*, like evolution.

      On the "evolution" (technically modern evolutionary synthesis) comment,

      At least 90% of laymen have no concept of what the theory says or predicts, nor how it is tested. The way the theory gets presented in high schools across the country is absolutly unacceptable. Such a muddle, confused, and illogical presentaion of science directly leads to such pseudoscience as intelligent design. Experience has forced me to agree with von Mises, public schools should be banned from teaching science because they incapable of presenting it correctly and will only cause confusion.

Britney Spears sucks in more ways than I can count, but I see no intrinsic value in classical music over any other form of music. You really want to know why Britney Spears outsells music that doesn't suck? It's because the music industry thinks its only consumer is the 13-22 crowd. Britney Spears captures probbably half of that age range, so she sells a lot.

      Now, to relate all of this back to the original article. What percentage of medical breakthroughs and research have anything to do with cumulative knowledge? What percentage is just purely money driven?

      I don't even know where to start with this statement. My guess is a lot of research isn't driven by pursuit of money. Just look at the research done at major universities and you'll find most of it isn't profit driven. Research that isn't profit driven is important because companies don't like funding things whose value isn't immediately apparent. When you take on that attitude you get a bit of tunnel vision. There's obviously a lot of research that is profit driven. What's wrong with that? Without it you'd just have less research going on, not more. Unless the profit driven research is somehow threatening the non-profit driven research I fail to see any problem with profit driven research.

      It's only my opinion, but "we" as a civilization will show true evolution when we take use of true knowledge and think less about everything as "business". Business is an artifact. Truth and knowledge serve more faithfully

      I'd agree that this current trend toward looking at everything as "business" is pure insanity. I'm not sure that "truth and knowledge" are the perfect goals we should all be striving for. "truth and knowledge" are abstract ideas and not actual goals to be sought after.

  16. Re:Not teaching science in schools is not an optio by HiThere · · Score: 4, Insightful

    Personally I believe that the problem is the increasing centralization of control over the schools. This includes all Federal interference and all state interference.

    Schools should be funded locally, and have local control. Unfortunately, the various levels of government have stolen the sources which were traditionally used to fund schools, so local funding is a problem which needs solution. This doesn't make it any less necessary. If the local students are to be taught lies, it should be because the local citizens have decided that that's what they want their children taught. (They will suffer the appropriate consequences...but their folly should not be forced on everyone else.)

    This has been my position for over 2 decades, and everything I've seen during that period of time has only reinforced the opinion. Only at the college or university level should the state (e.g., Idaho or Pennsylvannia) have any involvement. The states should run the colleges, because specialized education needs to draw from too large an area of population for local funding to be reasonable. They should be tuition free, but have appropriately difficult admissions requirements, and may limit the number of open spots for admission. (The state can decide how many English majors it needs to educate, and how many BioChemists, and fund that many classes of the appropriate type.)

    At all levels, private schools should continue to be an option.

    Some will argue that this will unfairly penalize the children of poor cities. In my experience in those cities the federal government alone extracts more funds nominally for education than are expended on schooling by all levels of government combined. This may not be true everywhere, but it's certainly largely true. Also, the most important parts of schooling don't require much in the way of funding, though they do require the cooperation of the parents. Thus if the parents will not cooperate with the local school, the school should have the right to refuse to allow the student to attend lessons. Disruptive students are not something that should be tolerated...but when schools are used in the way in which they are currently, that's what you get.

    That said, not all students are academically inclined. There needs to be a flexible "tracking" system, which allows those mechanically inclined to develop their skills as well as a track which allows the academic students to develop THEIR skills. I envision one hour per day during elementary school (after third grade) where students experience are instructed in "enrichment specialties", which should include things like band, set theory (arithmetic should be mainstream...by rote, and sorry), wood/metal/plastic shop, etc.

    OTOH, this requires a fairly large elementary school. Other benefits would accrue if elementary schools were local enough that all students could walk to them. That way the neighborhood kids would study together. This would probably mean that, e.g., grades K-3 would all be taught in the same room by the same teacher. (If you have enough students to split this in two, perhaps you could split them by distance rather than by age.) This WOULD be an acknowledged combination school and babysitting service, and play areas would be an important part of the situation. Teachers in this class would be expected to LIVE in the school, and keep it open. Provisions for substitutes would be necessary. Etc. Class sizes would be small, but the salaries would be enough to live on given the free rent. (I envision that most of these teachers would start out as mothers raising their kids. So room would need to be sufficient to handle not only the teacher, but also a husband or other partner and their children. With a safe fenced area around it which is the school yard.)

    N.B.: A lot of what I'm proposing is just my idea spinning of how it might ideally work out. The important parts are:
    1) No central control.
    2) Local choice on funding & curricula & environment.
