    This sounds like an interesting article that someone took the time out to put up here on Diigo. There's only one problem, this seems to be some sort of "pay to view" site. Visitors actually cannot see the article in question (well, they get a 2-paragraph preview). Diigo friends, please don't point to sites that don't give the full information.

    Actually, one need not pay, but to read the whole article, one does have to sign in - the account is free, and I understand some don't want to sign in. Still, the article raises some good points.

  • Few other clear-cut differences between boys' and girls' neural structures, brain activity, or neurochemistry have thus far emerged, even for something as obviously different as self-regulation.
  • Our actual ability differences are quite small. Although psychologists can measure statistically significant distinctions between large groups of men and women or boys and girls, there is much more overlap in the academic and even social-emotional abilities of the genders than there are differences (Hyde, 2005). To put it another way, the range of performance within each gender is wider than the difference between the average boy and girl.

Grove Art: Subject Guide in Oxford Art Online - 12 views

  • the Renaissance was a period when scholars and artists began to investigate what they believed to be a revival of classical learning, literature and art. For example, the followers of the 14th-century author Petrarch began to study texts from Greece and Rome for their moral content and literary style. Having its roots in the medieval university, this study called Humanism centered on rhetoric, literature, history and moral philosophy.

Looking in the Wrong Places | Edge.org - 5 views

  • 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.

Circumcision of the Heart in Leviticus and Deuteronomy: Divine Means for Resolving Curs... - 0 views

  • These three uses of “uncircumcised” imply that the foreskin is an impediment or obstacle to hearing, speaking, and producing good fruit. That is, the state of being uncircumcised impedes something, which, if it did not have the foreskin, would otherwise be prepared for true function and vitality. But since it has the foreskin, it is impeded
    • Philip Brown
       
      Excellent assessment up to this point. The conclusion "and will die," however, has no clear basis in the evidence for uncircumcised ears, lips, or fruit.
  • There is a progression in Leviticus from “outward” holiness to “inward” holiness or better, from the holiness symbolized in sacrifice, cult, and purity laws to holiness exhibited in the obedience of a prepared and consecrated people which Leviticus 17-27 envisions.
  • The foreskin of their heart was the cause of their stubbornness in 24:10-23, which led to God’s curse coming upon them in exile. They became as the “foreskined fruit trees” in Leviticus 19:23 that were unable to yield fruit. Their hearts still had the foreskin, the impediment or obstacle which prevented them from vital covenant faithfulness and ensuing blessing
  • ...5 more annotations...
  • Within this scheme, Leviticus presents the humbling of the foreskin of the heart as the resolution to the stubborn heart which brought the people into exile. Heart circumcision will bring the blessing of restoration.
  • It is in the context of the covenant curses that our reference to heart circumcision occurs in Leviticus 26:41, revealing that Israel had an internal heart problem which led them to curse God and therefore undergo his covenant curses.
  • Leviticus 26 describes the outworking of the blessing, curse-exile, and return from exile
  • Deuteronomy presents circumcision of the heart as important means for attaining the Deuteronomic vision of loyalty from a devoted heart.4
