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.

  • 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.

MediaShift . How Twitter is Reinventing Collaboration Among Educators | PBS - 85 views

  •  
    "Before the advent of Twitter, most educators I know had limited opportunities to collaborate with colleagues outside their building. Some subscribed to listservs or participated in online forums, but these outlets lacked critical mass; teachers also networked at in-person conferences and training sessions, but these isolated events didn't provide ongoing support. Enter Twitter. I've heard many educators say that Twitter is the most effective way to collaborate and that they've learned more with Twitter than they have from years of formal professional development."

Education Week Teacher: Teaching Secrets: Communicating With Parents - 1 views

  •  
    Teaching Secrets: Communicating With Parents By Gail Tillery Premium article access courtesy of TeacherMagazine.org. You will face many challenging tasks as a new teacher. Dealing with parents is probably among the most intimidating, especially if you are young and in your first career. While communicating with parents can be tricky, a little preparation will help you to treat parents as partners and to be calmer when problems arise. Here's the first rule to live by: Your students' parents are not your enemies. Ultimately, they want the same thing you want, which is the best for their children. By maintaining respectful and productive communication, you can work together to help students succeed. Second, whenever problems arise, remember that parents are probably just as nervous about contacting you as you are about returning the contact-and maybe more so. I'll confess: Even after 26 years of teaching, I still get a little frisson of fear in my belly when I see an e-mail or hear a voicemail from a parent. But I have seen time and again that parents are often more nervous than the teacher is-especially if their child doesn't want them to contact the teacher. Indeed, some parents may even fear that if they raise concerns, their child will face some kind of retaliation. Remember that parents' tones or words may reflect such fears. In your response, try to establish that everyone involved wants to help the child. Here are some practical tips for communicating effectively with parents: Contact every parent at the beginning of the year. Do some "recon." Telephone calls are best for this initial contact, since they are more personal than e-mail. Ask the parent to tell you about his or her child's strengths, weaknesses, likes, dislikes, etc. Make sure to ask, "What is the best thing I can do to help your child succeed?" Remember to take notes! Once you've gathered the information you need, set a boundary with parents by saying, "Well, Ms. Smith, I have 25 more parent

Nova Fabric of the cosmos The illusion of time full video - YouTube - 48 views

  • The Evolution of Time and the Carnot Cycle at the Edge of the Universe
  •  
    We are all time travelers... drifting through time at a steady pace, one moment at a time. In what direction are we moving through time? Or does time move through us? How many dimensions of time are there? Though slightly allegorical, three-dimensional time offers physics new parameters, accounting for conventional and exotic physical phenomena, while maintaining the conservation of energy and symmetry groups found in physical law.  I began playing with the idea that all of physics could be reduced to just interactions between spatial and temporal coordinates. I wondered if inertia and momentum might be composed strictly of temporal components. This would require extra time dimensions. Could inertia or momentum be used as indicators of multi-dimensional time? What about charge, spin, and other properties of matter? Answers to some of these questions appeared to reside in neutrino research, specifically neutrino flavor oscillation.  The universality between Thermodynamics and Temporal Mechanics can reduce the fundamental forces of nature into a single expression, a new equivalence principle, which can be used as the generator for the evolution of time. Once Quantum Mechanics is seen through the lens of three-dimensional time, the EPR paradox looses its mystique. The speed of light may be restricted to a set speed limit within each individual frame of reference, however, frames of reference can undergo periods-of-time at varying rates of the passage-of-time. If the positive side of absolute zero is a state of condensed matter, what is on the negative side of absolute zero? Uncondensed matter?  The anti-matter aspect of the Dirac equations may have been misinterpreted. The convention is to assume that "matter" is composed of "particles" distinctly different from "antimatter" composed of "antiparticles". The assumption of one time dimension locks in this interpretation of the Dirac Equations. However, the uniform production of particles and antipa

Conformity vs Individuality in Education - 4 views

    "At its inception in the Victorian era, mass education in the UK focused very much on conformity, based on the prevailing 'factory production' mindset on the age. But how much has changed? With top down curricula and a rigid exam system testing the merest fraction of what is actually important, has education really left the production line behind?"

12/21/12: Definitely Not the End of the World | Wired Science | Wired.com - 29 views

  • There is not a single iota of evidence that large-scale planetary alignments cause changes in geologic events – like earthquakes and eruptions – on Earth. The only celestial bodies that could play some role – and there is some evidence that suggest that they may, in minor ways – are the Sun and the Moon. This is due to their relative close proximity (especially the moon) and their mass. I’ve covered some of this in my discussion of why the so-called “Supermoons” are silly and play no role in increasing/decreasing geologic events. What about the alignment with the galactic center? The center of the galaxy must exert some force on the Earth (and solar system) or we wouldn’t be orbiting it. However, beyond that fact that alignments like this happen all the time, the force that the galactic center exerts on Earth is ~0.00006x that of the Moon on Earth and ~0.00000037x that of the Sun, doesn’t it seem a little ridiculous to claim that the galactic center can change anything on Earth if the Sun and the Moon cause little-to-no effect on geologic events?

      Sounds like an intervention block, something many buildings have or are looking at.
  • small but growing number of schools are attempting to boost the achievement of low-income students by shifting enrollment to place more low-income students in mixed-income schools. Socioeconomic integration is an effective way to tap into the academic benefits of having high-achieving peers, an engaged community of parents, and high-quality teachers.
  • A 2010 meta-analysis found that students of all socioeconomic statuses, races, ethnicities, and grade levels were likely to have higher mathematics performance if they attended socioeconomically and racially integrated schools (Mickelson & Bottia, 2010).

  • Rumberger and Palardy (2005) found that the socioeconomic composition of the school was as strong a predictor of student outcomes as students' own socioeconomic status.
  • Socioeconomic integration is a win-win situation: Low-income students' performance rises; all students receive the cognitive benefits of a diverse learning environment (Antonio et al., 2004; Phillips, Rodosky, Muñoz, & Larsen, 2009); and middle-class students' performance seems to be unaffected up to a certain level of integration.
