  • sociology. Forget taxonomy, ontology, and psychology. Who knows why people do what they do? The point is they do it, and we can track and measure it with unprecedented fidelity. With enough data, the numbers speak for themselves.
  • The big target here isn't advertising, though. It's science. The scientific method is built around testable hypotheses. These models, for the most part, are systems visualized in the minds of scientists. The models are then tested, and experiments confirm or falsify theoretical models of how the world works.
  • But faced with massive data, this approach to science — hypothesize, model, test — is becoming obsolete.

    I dissagree. Maybe for someone who can cope with the massive scale Google works with but for the average student bah humbug. As far as the students I see the scientific method still needs to be taught as they need a lot of help learning how to gather reliable information from the web. As far as google is concerned the students simplistic, unevaluated searches are as valuable as someone who actually understands what they are looking for or maybe more valuable because more students are doing almost thoughtless searches. The real need is a good course, hopefully online, to teach students how to do a reasoned search. agoogleaday is a start.

    From site: "The best way for students to learn science is to experience problems that challenge science, and the thought, habits of mind and actions associated with trying to solve them. This implies opportunities for authentic, inquiry-based learning. Problem-based learning (PBL) is a powerful vehicle for this, in which a real-world problem becomes a context for students to investigate, in depth, what they need to know and want to know (Checkly, 1997). It is a robust, constructivist process, shaped and directed primarily by the student, with the instructor as metacognitive coach."

Can Mary Shelley's Frankenstein be read as an early research ethics text? | Medical Humanities - 7 views

  • Can Mary Shelley’s Frankenstein be read as an early research ethics text?

      SEE HEAR
  • Frankenstein is an early and balanced text on the ethics of research upon human subjects and that it provides insights that are as valid today as when the novel was written.
  • Mary Shelley conceived the idea for and started writing Frankenstein in 1816 and it was first published in 1818.1 In its historical context, the earlier 17th and 18th centuries had seen the early signs of the rise of science and experimentation. Francis Bacon (1561–1626) had laid the theoretical foundations in his “Great Insauration”2 and scientists such as Boyle, Newton, and Hooke developed the experimental methods. Sir Robert Talbor, a 17th century apothecary and one of the key figures in developing the use of quinine to treat fevers, underlined this: “the most plausible reasons unless backed by some demonstrable experiments seem but suppositions or conjectures”.3
  • ...5 more annotations...
  • The 18th century saw the continued construction of foundations upon which all subsequent medical experimentation has been built.
  • Lady Mary Montagu promoted smallpox vaccination; its proponents experimented on prisoners to study its efficacy, and James Jurin, the secretary of the Royal Society, developed mathematical proof of this in the face of ecclesiastical opposition.4 Many of the modern concepts of therapeutic trials were described although not widely accepted. Empirical observation through experimentation was starting to be recognised as the tool that allowed ascertainment of fact and truth. An account of Dr Bianchini’s experiments on “Le Medicin Electrique”, reported to the Royal Society explains that “The experiments were made by Dr Bianchini assisted by several curious and learned men … who not being able to separate what was true … determined to be guided by their own experiments and it was by this most troublesome though of all the others the most sure way, that they have learned to reject a great number of what have been published as facts.”5
  • Similarly, Henry Baker’s report to the Royal Society, describing Abbe Nollet’s experiments, outlined the need for comparative studies and that “treatment should not be condemned without a fair trial”6 and a Belgian doctor, Professor Lambergen, describing the use of deadly nightshade for the treatment of breast cancer wrote “Administration of this plant certainly merits the attention of the medical profession; and surely one may add entitles the medicine to future trials … nevertheless the most efficacious medicines are such if its efficacy by repeated trials be approved.”7 In the mid 18th century James Lind conducted the first controlled trial to establish a cure for scurvy and his Treatise on the Scurvy contains what could be seen in modern terminology as the first “review of the current literature” prior to a clinical trial.8
  • Her motives for writing Frankenstein are more difficult to define. In her introduction to the 1831 edition she writes that she wanted her work to … speak to the mysterious fears of our nature and awaken thrilling horror—one to make the reader dread to look round. If I did not accomplish these things, my ghost story would be unworthy of its name … (p 7, p 8)
  • The 1818 preface, written by Percy Bysshe Shelley, indicates a deeper purpose. He wrote that the story recommends itself as it “…affords a point of view on the imagination for the delineating of human passions more comprehensive and commanding than any which the ordinary relations of existing events can yield…” (p 11) and that “…I am by no means indifferent to the manner in which ... moral tendencies (that) exist in the sentiments of characters shall affect the reader…”(p 12).

    From site: Although YouTube has something of a reputation as a repository for the inane mental diarrhea of stunted man-children injuring each other for cheap laughs or shrill teenage drama queens shrieking like harpies over the latest bland, interchangeable lump passing as the epitome of masculine beauty, many others thankfully take advantage of its services as a portal to share their knowledge and educate viewers. While few of the scientific offerings formally follow the scientific method or test an explicitly stated hypothesis, even those videos veering more towards demonstrating various principles, theories, and laws still offer visitors a chance to learn something about how the world around them operates.

    I disliked this video. Is my classroom extraordinary? The rest of the classrooms in the U.S. have unmoving, silent children stuck in desks all day? The students don't talk to each other? They don't collaborate to solve problems? They don't read? They don't write in order to analyze and express opinions? They don't use math manipulatives, do science experiments, build, draw, and do projects? They don't laugh together, digress, and then get back on track? Because that's what we do. It doesn't strike me as a response to the Industrial Revolution as much as a response to students' curiosity and to their future needs. "If we get it right, kids won't even know they're learning something." So, we're doing it wrong if the kids are actually aware that they're learning? Better they should be metaphorically anesthetized by the computer experience? We don't want them inoculated against feeling the discomfort of struggle. Every respected neuroscientist on the planet says struggle is necessary to wire neurons together, which is the physical manifestation of learning. The simulation of the village looks very cool. I love computers. But if all their learning about ancient Rome is based on this simulation, where are the primary sources? Will students encounter any? Or is their experience of the village based on someone else's interpretation of primary sources? If so, then someone else gets to decide what is important to include in the Roman village. They get to choose and interpret the facts that are used to create the virtual ancient Roman experience. That goes against best practice teaching of the social sciences.

    "I never realised that doing group work could be such a controversial activity in teaching until I discovered Twitter! This post is not going to consider if you should use group work, but how to do it effectively should you choose to use it as part of your teaching repertoire. As a science teacher, group work is a given. It just isn't practical to equip every student with every piece of equipment they need to complete an experiment on their own. There is also the issue of time, space and safety, all of which, I feel, may be compromised if you have 28 overenthusiastic students trying to do an experiment at the same time."

NaturalScience senseperception paradigm

shared by Gareth Jones on 19 May 18 - No Cached
  • We should be very careful in thinking about whether we’re working on the right problems. If we don’t, that ties into the problem that we don’t have experimental evidence that could move us forward. We're trying to develop theories that we use to find out which are good experiments to make, and these are the experiments that we build.   We build particle detectors and try to find dark matter; we build larger colliders in the hope of producing new particles; we shoot satellites into orbit and try to look back into the early universe, and we do that because we hope there’s something new to find there. We think there is because we have some idea from the theories that we’ve been working on that this would be something good to probe. If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.
  • I’m still asking myself the same question that I asked myself ten years ago: "What is going on in my community?" I work in the foundations of physics, and I see a lot of strange things happening there. When I look at the papers that are being published, many of them seem to be produced simply because papers have to be produced. They don’t move us forward in any significant way. I get the impression that people are working on them not so much because it’s what they’re interested in but because they have to produce outcomes in a short amount of time. They sit on short-term positions and have short-term contracts, and papers must be produced.
  • The field that I mostly work in is the foundations of physics, which is, roughly speaking, composed of cosmology, the foundations of quantum mechanics, high-energy particle physics, and quantum gravity. It’s a peculiar field because there hasn’t been new data for almost four decades, since we established the Standard Model of particle physics. There has been, of course, the Higgs particle that was discovered at the LHC in 2012, and there have been some additions to the Standard Model, but there has not been a great new paradigm change, as Kuhn would have put it. We’re still using the same techniques, and we’re still working with the same theories as we did in the 1970s.
  • ...10 more annotations...
  • That makes this field of science rather peculiar and probably explains why there hasn’t been much progress. But it’s not like we don’t have any questions that need to be answered. There are a lot of questions that have been around for decades. For example, what is dark energy? What is dark matter? What are the masses of the Standard Model particles? And what’s up with the foundation of quantum mechanics? Is a theory that's fundamentally not deterministic, where we cannot predict outcomes, the last word that we have, or is there something more to it? Is there maybe another underlying structure to reality?
  • but we haven't reached the fundamental level. Maybe we will never reach it. Certainly, the theories that we have right now are not all there is. The question is, of course, if we don’t have any guidance by experiment, how do we make progress? And are we doing the right thing?
  • We’ve reached this point where we have to carefully rethink if the criteria that we’re using to select our theories are promising at all. If one looks at the history of this field in the foundations of physics, progress has usually been made by looking at questions that, at least in hindsight, were well posed, where there was an actual mathematical contradiction. For example, special relativity is incompatible with Newtonian gravity. If you try to resolve this incompatibility, you get general relativity.
  • There are various similar examples where such breakthroughs have happened because there was a real problem. There was an inconsistency and people had to resolve it. It had nothing to do with beauty. Maybe beauty was, in some cases, the personal motivation of the people to work on it. There’s certainly some truth to this, but I don’t think it’s good to turn this story around and say that if we only pay attention to this motivation that comes from ideals of beauty it will lead to progress.
  • If we are working with the wrong theories, we are making the wrong extrapolations, we have the wrong expectations, we make the wrong experiments, and then we don’t get any new data. We have no guidance to develop these theories. So, it’s a chicken and egg problem. We have to break the cycle. I don’t have a miracle cure to these problems. These are hard problems. It’s not clear what a good theory is to develop. I’m not any wiser than all the other 20,000 people in the field.
  • The way that research is funded in foundations of physics and in many other fields just puts a lot of things at a disadvantage that are not pursued anymore. Typically, everything that takes longer than three years to complete, no one will start it because they can’t afford it. They can literally not afford it.
  • Who makes the decisions about the funding? Superficially, people say that it's a funding agency, so it’s the university who get to hire people. But that puts the blame on the wrong party. In the end it’s the community itself who makes the decisions. What do the funding agencies do if they get a proposal? They send it to reviewers. And who are the reviewers? They're people from the same community. If you look at how hiring decisions are being made, there’s some committee and they are people from the same community. They have some advisory boards or something, which contains people from the same community.
  • Even if that wasn’t so, what the people in these committees would be doing is looking at easy measures for scientific success. Presently, the most popular of these measures are the number of publications and the number of citations. And maybe also whether the person has published in high-impact journals. So, these are the typical measures that are presently being used. But what do they measure? They primarily measure popularity. They indicate whether somebody’s research is well received by a lot of people in the same community. And that’s why once a research area grows beyond a certain critical mass, you have sufficiently many people who tell each other that what they’re doing is the good thing to do. They review each other’s papers and say that that’s great and it's what we should continue to do. It’s a problem in all communities that grow beyond a certain size.
  • I later came to the United States and then Canada, and that gave me the opportunity to learn a lot about quantum gravity. I also figured out that much of what goes on in quantum gravity is very detached from reality. It’s pretty much only mathematics. Yes, the mathematics is there, but I still don’t know if it’s the mathematics that describes reality.
  • That’s the very reason why we don’t normally think of gravity as a weak force. It’s the only force that is left over on long distances, and the reason for this is that it adds up. It gets stronger the more mass you pile up. More precisely, we should say that the reason we find it so hard to measure quantum gravitational effects is that we either have a particle that has very pronounced quantum properties, like, say, a single electron or something like that, but then it’s so light that we cannot measure the gravitational field. Or we have some object that is so heavy that we can measure the gravitational field, but then it doesn’t have quantum properties. Okay, so that’s the actual problem.
