What is Science?

What is science? I do not mean just the dictionary definition, though perhaps we need to start with something commonly accepted like that in order to understand more fully what science is.

(This came up in the discussion of "Ego Depletion." My comments here were too long and involved for that. So, I offer this as a new topic.)

A few years ago, before going under the knife at a university research and teaching hospital, I signed an agreement that I understood that medicine is an art, not a science, and that outcomes are not predictable. Maybe that is why the German word for medical doctor is "der Arzt." But medical practice certainly depends on science, does it not? And they do have medical research, which we hope is practiced as a science, rather than an art like ballet or ceramics.

(Granted that art has a lot of science in it: chemistry of pigments, physics of firing, anatomy, botany... it is all there if you care to know. Does "the science of painting" make sense?)

In this discussion, blarman, WilliamShipley, and lucky differentiated engineering from science. We commonly accept the generalization that scientists discover basic laws; and engineers apply those to the creation of new products; and technicians maintain those creations. That is how things are today. History provides a different model.

The steam engine came before thermodynamics. The telegraph and telephone antedated Maxwell's Equations. Luther Burbank died 20 years before DNA was announced. Similarly, William Smith, who predicted and found the presence of coal by the fossil record of England, died 20 years before The Origin of Species (-- http://necessaryfacts.blogspot.com/20....

Inventions are largely the improvements of technicians, not the direct applications of theories to new practices.

Computer science may not yet be a science, but the summary work we are doing now will be generalized into new theoretical models.

In William Gibson's "Bridge Trilogy" set in the immediate future, some of the viewpoint characters are artists in a beach house, majoring in Media Science at UC Berkeley. It is not a science yet...

But, what, then is a science?

I look at the practice. If a pursuit consciously chooses the scientific method, then it is a science.

We all know the basic Scientific Method:
1. Observe some aspect of the universe.
2. Invent a tentative description, called a hypothesis, that is consistent with what you have observed.
3. Use the hypothesis to make predictions.
4. Test those predictions by experiments or further observations and modify the hypothesis in the light of your results.
5. Repeat steps 3 and 4 until there are no discrepancies between theory and experiment and/or observation.

Norman Edmund (1916-2012), founder of Edmund Scientific - and who has not been a customer? - taught a 14-step process.
http://www.scientificmethod.com/index...
Steps or Stages of the Scientific Method
  
1. Curious Observation
2. Is There a Problem?
3. Goals & Planning
4. Search, Explore, & Gather the Evidence
5. Generate Creative & Logical Alternative Solutions
6. Evaluate the Evidence
7. Make the Educated Guess (Hypothesis)
8. Challenge the Hypothesis
9. Reach a Conclusion
10. Suspend Judgment
11.Take Action

Supporting Ingredients
12. Creative, Non-Logical, Logical & Technical Methods
13. Procedural Principals & Theories
14. Attributes & Thinking Skills
http://www.scientificmethod.com/index...

The way I learned it - five steps, seven, or more - publishing your findings is always the last step. That can mean just recording this in your notebook, if the results are intermediary. But in any case, you must finalize the process by making it possible for others to replicate the work.

That was perhaps the essential truth that separated chemistry from alchemy in Robert Boyle's Sceptical Chymist (1661). Boyle argued for open disclosure of means and methods. That openness - your own open mind open to the minds of others - may be the sine qua non of science. It also speaks to the tension of science in the context of national security. That is nothing new. Projective geometry was held as a French military secret. Can anything secret be a science?

    No Evidence That Industry Funding Increases Research Misconduct
    To the Editor:

    In “Research Scrutiny” (The Chronicle Trends Report, February 29), you present a dangerously misleading characterization of industry-sponsored research and zero evidence industry funding is more likely to increase research misconduct.
    […]
    More importantly, you ignore an obvious truth: Nobody gains more from accurate, verifiable science than industry. The market is an unforgiving arbiter of both performance and value and companies will derive no benefit by fudging research in order to produce defective products for customers to purchase. Instead, you exploit America’s most popular binge: company bashing.

    Uncomfortable Science and the Embargoed WADA Doping Study
    Back in 2011 WADA - the World Anti-Doping Agency - provided research funding to a group of researchers to conduct a study on the prevalence of doping in elite track and field. The researchers conducted their research and then prepared a paper for publication.
    […]
    . . . more than one year after completion of the study, did it become clear to the authors that WADA could not act independently from IAAF [International Association of Athletic Federations -MM], because WADA had made an agreement with IAAF which was not disclosed to the research group. According to this agreement, WADA would need permission from IAAF in order for us to submit the paper . . .

    dbhalling You have it exactly right your essay says what I have been trying to convey for a long time in this and related threads. Very nice work.

    Warrior ants do not have volition. (At least the claim is easy to make. No one has asked them.) Only humans are volitional. That other such beings exist is highly likely. The laws that apply to us must apply to them. They may not have trial by jury, but if they are social creatures at all, they must have rights because rights are a requisite for social living. More deeply rights apply only to rational, volitional beings.

    Myself, I differentiate ethics from morality. (Having gone around on that with my Objectivist comrades has been fruitless.) Morality is for the individual. On his island, Robinson Crusoe needed morality the same as he needed language: for his survival. Ethics are social. On a crowded city bus, should you give your seat to a pregnant woman? Morality exists like the laws of chemistry. Ethics depend on the specific, contextual nature of the beings and the natures of their societies. However, ethics cannot contradict morality because morality is (however you want to think of it) "higher" or "more basic." Morality is the foundation for ethics. Morality supersedes ethics.

    By "morality of volition" I mean the fact that the presence of volition necessitates morality.

    "Morality of volition" is an interesting concept. To me it implies that there exists a system of universal ethics that like the law of gravity applies equally to all entities. From this we should be able to reconcile the morality of volition of warrior ants as they destroy other ant colonies with the actions of a Mother Teresa. That would seem to be a rather tall order. But that is why I chose physics over sociology. It's a lot simpler.

    I have read AS three times; when it first came out, then again about 20 years ago, and finally about 3 months ago. I have AS I, II, and III the movies and have read everything written by Ayn Rand that I have been able to find including some of her more obscure short stories and essays. As far as my statement being diametrically opposed to objectivism I don't understand what you mean. As a scientist I tend to be very pragmatic. By this I mean that learning what things do and how things work is a useful goal and modern technology is testimony to the efficacy of that approach. Knowing what things are, however, is an entirely different matter. For example, we have fairly comprehensive knowledge of what electrons do. This knowledge provides the ability to design and construct systems of enormous complexity and these systems usually work. However, if someone asks me what an electron IS I would have to say I don't have a clue. We can talk about quarks and mesons, and gluons, positrons, muons, neutrinos and the like but these are just names we give to particles whose existence we can only observe by inference. No one has ever seen a subatomic particle. None the less we are reasonably confident that they exist. We make observations of the artifacts that these particles leave behind such as trails in a cloud chamber or flashes of light in a scintillation crystal but the particles themselves have never been directly observed. The problem appears to be that underlying reality is more complex than any of our theories and may even be more complex than any finite theory CAN be. Our understanding of the behavior of reality can be viewed as a sub set of that reality. It is not complete but it is good enough that we can use it. An important part of science is to expand that knowledge fully realizing that complete understanding may never be possible.

    The morality of volition is as universal as the law of gravity, and, like the laws of mathematics, exists independent of the existence of such creatures. By analogy, the chemistry and physics of water do not depend on the actual existence of water. It is a "tree in the forest" - it does not matter who is there to "hear it fall." (And the Moon is still there when you look away.)

    ProfChuck, it would be interesting to me, for one, to learn how you came to be here. Your statement above is diametrically opposed to even small-o objectivism. Capital O-Objectivists will put you in the same camp as the political progressives and academic post-modernists.

    I assume that you at least saw the movie version of Atlas Shrugged. Have you read the book?

    Because your statement above was open and honest, I will not give it a Thumbs Down. It at least engenders discussion.

    Yes. Reproducibility does mean getting the same results in the same experiments, and if an experiment isn't reproducible then something is wrong (either an error, or unaccounted for factors). However that just pertains to the validity of the experiment: when it comes to the theory or idea the experiment is testing, the more independent ways it cam be addressed, the better!

    Most scientists realize that science is never "settled". The idea that climate change science is settled is utter nonsense. Our understanding of physical reality is in a state of constant flux. Scientific theories can be relied upon to be incomplete. That does not necessarily mean they are wrong just that they don't tell the whole story. Copernican cosmology, Newtonian dynamics, Einstein's relativity are all recognized as incomplete even in most cases by their creators. However, I have a minor quibble with the notion that science is a search for "truth". My difficulty is probably semantic but because we have never been able to understand something completely the concept of truth is fraught with difficulties and is a largely metaphysical idea. As a scientist I have always regarded my profession as a search for understanding. For example, I have at least a partial understanding of how gravity behaves. This understanding is good enough that I can design a navigation process that guides flight from one planet to another. Does that mean I know the "truth" about gravity? I don't think so. I just understand a little about how it works. I have used this analogy before. Someone once asked me if I "believed" that two plus two makes four. My response was "No." But because I understand the circumstances under which two plus two makes four I can use that understanding to employ mathematics as a tool. Unfortunately, Understanding is a lot easier than believing. But sometimes people think it's the other way around.

    This sounds more like a statement about ethics than physics. Physical "laws" are statements about our understanding of some observable property of reality. The idea that volitional creatures have rights may be ethical but ethics is an invention not a discovery.

    Nicely said. Einstein recognized that Newtonian dynamics was not incorrect but it was incomplete. Newton holds well enough that we can use its principals to navigate a spacecraft from one planet to another but when velocities become very large and matter becomes very dense Newtonian physics begins to loose accuracy. This is not because Newton was wrong but because at the boundaries of his theory there are forces and phenomena that play an increasingly significant roll. Newton was unaware of these simply because the discoveries of people like Faraday and Maxwell had not yet taken place. It is interesting to note that the Newtonian equation describing escape velocity; Ve=sqrt(2Gm/r), can be reformulated to the Schwarzchild equation that describes the event horizon of a non rotating black hole. Rs=2Gm/c^2.
    Does this mean that black holes were predicted by Newton? Probably not but his theory does allow for them.

    The cosmological principal simply states that the laws of physics, both the ones we know and those yet to be discovered, are uniform and consistent throughout the cosmos. The notion of " the universe playing fair" is a philosophical interpretation of that assumption and while poetic it is not strictly scientific. The cosmological principal has survived every test we have been able to perform. Observation of the spectra of distant stars reveals that our understanding of atomic transitions is consistent with emission and absorption lines seen both in our own sun and in stars located in a galaxy that is millions of light years distant. The orbital behavior of the planets and their satellites is consistent with Newtonian dynamics and appears to follow the same "rules" everywhere we look. Ergo, the cosmological principal is strengthened. Does that mean that the consistent behavior of the universe is the result of some act of conscious volition on the part of the cosmos at large? No! It just means that the concept bears a useful and, so far, a consistent relationship to reality.

    If knowledge is "finite" (as you say "limited to what is"), then it cannot be unlimited (as you say, "there is always more to find out."). Either-or. We do not know what gravity "is". We only know how it operates. Newton disliked the idea of action at a distance. Feynman worked with "fields" his entire life, but wondered if our perception of the "field" is only the manifestation of something "underneath". On the other hand, we know what a chicken is…

    And yet…
    "If gravity be an inherent quality, pent up and quiet in matter, how can it produce action at a distance? If it be an incessant emanation from matter in all directions, why does not matter become exhausted of it? If it emanates only towards attracting bodies, how can it know in what direction to travel? Thus it may be seen that the admission of attraction as an inherent quality precludes all rational inquiry. Yet so far as man has studied and comprehended nature, her ways are in accordance with reason and with the equivalent relation of cause and effect." — Memoir on the Constitution of Matter and Laws of Motion, by J. L. Riddell, New Orleans Medical Journal, March, 1846, volume II, page 602.

    So, Einstein said that matter warps the space-time continuum. But you deny that space-time is curved. Do you have a better explanation?

    Thanks for yet another cogent statement, ewv. I suggest that if you have no interest in reading Popper's The Logic of Scientific Discovery that you at least read the Wikipedia entry on Falsifiability. It is important to extract from that what can be integrated into an objective understanding of Science as a Profession (in particular) and knowledge (in general).

    Popper regarded astrology and Freudian psychology as pseudo-sciences because no test could disprove them.

    That is where your claim fails, that "Science is ever expanding knowledge … Science advances when more scope and precision become possible, adding to our knowledge through contextual principles." I assure you, having socialized with them on several occasions that modern astrologers consider themselves far advanced over the star-readers of old, and, of course, distance themselves from the daily horoscope. Conspiracy theorists from the mundane to the extra-terrestrial always find new and better evidence to expand their understanding. Just consider the Millennarians within the political right, including many self-identified "Objectivists" who insist that the end of the world is at hand. Every day's news brings ever more evidence of what they expect to believe, always expanding their knowledge, and widening their scope.

    What they all lack is admissions of the existence of facts that could disprove their theories.

    On the other hand, Newton's Laws of Motion are testable. Within whatever convenient range of measurement, if force were not equal to the product of mass and acceleration, we would find that out. That is what an experiment is: a test of falsifiability. In that, you are right, when you noted that Newton's mechanics was not "falsified". Not only does it provide a consistent explanation, tests to disprove it have failed. Freudian psychology and astrology have been falsified.

    That was a good response. I accepted the "playing fair" as a statement about "sense of life" the expectation that while the universe might not care, neither is it pernicious.

    That attitude was a change, a cultural shift, attributable to the Greeks of archaic times transitioning into the Classical age. They no longer feared the gods.

    I agree with you that in what is intended as a formal discussion here, personifying the universe as an entity that "plays fair" is a nice artistic device, but does not make a clear statement connecting metaphysics and epistemology

    Yes, the scientific method is the same as Objectivism. A successful working scientist who goes to church because he does not want to offend his family is not being consistent. Alone on his island, Robinson Crusoe survived by the scientific method, whether anyone knew about it or not. Those examples do not address the formal pursuit of Science by the Scientific Method.

    "Publication" can be limited to your own notebook. If you do not keep one, you are not doing science. You are just living a rational life of interested curiosity about the world.

    The informal life of interested curiosity also does not require any kind of an experiment. You could just look around you and ask questions and seek consistent answers without ever testing one, not even with an independent observation. In Anthem Equality 7-2521 could recreate the electrical lightbulb from the existing materials, but he says at the end that he does not know what the stars are. He may never know. He still led a life of rational-empirical (objective) enquiry, even though no science of astronomy existed at that moment.

    A true Keynesian would be faithful to all the tenets of Keynesian Economics including the one that says it will work as long as the interest can be paid.

    Those who deny or seek to find away around that one Keynesian truth are not Keynesian.

    Just as those who take an oath to the Constitution and immediately ask "Find me away around the Constitution" or 'the supreme court hasn't visited that particular portion yet.' are not Constitutional and their oath is a lie.

    That refrain has a purpose and that purpose is to enforce a state of self-delusion and reinforce their loyalty to the leftist collective entity by renouncing their own independence and ability to think or reason. The thinking and reasoning switch is in the off position whatever is put forth as the current party truth. The only independent action taken is - refuse to think, Do as told to do when told to do whatever it is.

    While we strive to recognize our ability and turn the thinking switch to the on position their goal is to padlock it shut with a welded key slot.

    Over or under simplification and your mentioning the non-aggression principle which is another way of saying Give Peace A Chance I'm finding have one common false premise. They fail to take into account some important feature of human nature.

    One can wish for 'peace' but then one can also wish for 'conflict' without the effort of stating how the balance is to be arrived at and maintained. Thus the delusion of inflation fails to recognize TANSTAAFL and turns a blind eye to those who must pay the bill.

    A leftist will just accept the party mantra. An Islamic would say It's God's Will. No problem with the pesky need for explanation..no need for thinking.

    And some will say I have to vote for evil ...I have not choice.

    They are correct. They choose to have no choice.

    ewv, I know you better by dint of having read more
    than just a few words from you. . after reading lots of
    word-products from you, I have an idea about how to
    understand what you mean. . words are not math,
    and it takes a whole bunch to allow what I called
    "triangulation" to get the real meaning. . stress
    analysis can involve bending, shear, tension, compression
    and many combinations of those. . by using more
    than just one formula, the engineer can home in on the
    very most likely failure zone, depending on the loads
    impressed on a material, a structure. . a good example
    is notch sensitivity. . the exact shape of a feature
    shaped like a notch, or dimple, or scratch, or impressed
    feature like a stamped ID number on a ford driveshaft,
    can raise stresses in extreme ways. . it's empirical
    knowledge which allows accuracy, and that requires
    testing to failure. . most engineers cannot afford that,
    so comparison of calculated results is required. . just like
    I compare your current words with those which I have
    seen in the past, to arrive at my best estimate of
    your current meaning. -- j

    We do understand gravity and evolution. Knowledge is always finite -- limited to what it is -- and there is always more to find out. Darwinian evolution does stand up to inquiry, especially with modern genetic evidence and explanation. Darwinian evolution is a specific theory, not just "life evolves". Competing hypotheses at his time, including the "God did it" version, differed in ways that ruled out the other ideas..

    Science is not "process". The false equation repeatedly leaves out conceptualization. The notions of avoiding measurement versus only measure is a false alternative. This is in turn used by anti-conceptualists influenced by the Logical Positivists and Pragmatists to wrap themselves in the virtue of measurement as they pretend they have a monopoly on it.

    Private corporate research labs such as Bell Labs, ATT&T, Xerox, and BBN are famous for their accomplishments. "Skunk works" unofficial projects are often the source of it and are tolerated because creativity cannot be predicted and scheduled.

    Galt's speech is the real meaning. It is long to provide the integration of many aspects, not to home in on something else.

    What do you mean by "triangulating" stress analysis calculations? You always have to identify and use essential features, determine sensitivity to relevant factors, and assess the accuracy of the results.

    Newton's mechanics was not "falsified". Science is ever expanding knowledge, not a sequence of exploded fallacies. No principles are omniscient or have "infinite" precision -- there is no such thing. Science advances when more scope and precision become possible, adding to our knowledge through contextual principles.

    That Newton's law of gravitation could not account for 43 seconds of arc per century in the precession of the perihelion of the orbit of Mercury, after all the other perturbations were accounted for, does not mean that it is false. There is no such thing as infinite precision. Newton's principles of gravitation remain true and as accurate as they have always been, and is still used daily in science and engineering. Without them, Einstein's discovery of a more complex formulation accounting for more detail could not have been done.

    Any conceptual, meaningful quantitative principle can in principle be measured and will or will not hold within some context of precision. Popper adds nothing to that. His philosophy offers no theory of the conceptual nature of science, replacing it as a-conceptual statements of "predictions" of measurements subject to an impossible standard of precision and omniscience in the name of "falsifiability". No wonder people who follow this anti-conceptual standard wind up as skeptics claiming that every theory is a disconnected falsehood waiting to be contradicted and replaced.

    Meanwhile, Einstein's theory has had spectacular success -- to another finite degree of precision -- on a very limited number of cases, with little in the way of conceptual understanding or reason to distinguish it from competing theories. This lack of conceptual distinction is reason to regard it as tentative.
