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

The message is now unpacked for the class. The jar represents our lives, and the challenge is to decide what we will fill our lives with. The large rocks represent those things which matter most in our lives. The gravel and sand the small things which occupy our time and keep us from what matters most. - How might this help us focus on what matters for our learners?

Micro-student loans for students in 3rd world countries. Outside of the United States and a handful of other countries, student loans just don't exist. No matter how well you did in school, no matter how good your grades were, no matter how hard you worked, if you don't have the cash up front or a rich uncle to co-sign for you, you just can't go to college. In many cases, Vittana loans are the first and only source of college loans for students in countries where we operate.

A team of physicists led by Caltech's David Hsieh has discovered an unusual form of matter-not a conventional metal, insulator, or magnet, for example, but something entirely different. This phase, characterized by an unusual ordering of electrons, offers possibilities for new electronic device functionalities and could hold the solution to a long-standing mystery in condensed matter physics having to do with high-temperature superconductivity-the ability for some materials to conduct electricity without resistance, even at "high" temperatures approaching -100 degrees Celsius.

What matters most GRIT!

Great post by Shelly Wright. It's not about the videos.

When I recently re-read the post, I didn't disagree with anything I'd said. Yet my brief love affair with the flip has ended. It simply didn't produce the tranformative learning experience I knew I wanted for my students .

Direct instruction is direct instruction no matter how you spin or flip it. While it does have its place, as all things do, we're reminded that the paradigm shift is not simply a matter of shifting an order of events. This is a solid post on the power of personalized learning.

Completion matters: the high cost of low #comm_college graduation rates http://t.co/Oa464OHc

"I am struck by both how resilient and fragile life can be. More so than in another other year, I have a stronger sense that learning matters and that I matter as a teacher So, with a mixed first week, I'm still struck by the lingering question: What does it mean to be a great teacher?"

The web is a space whose very abundance of information - and whose very informational infrastructure - trains our attention to follow our interests. And vice versa. In that, it's empowering information as a function of interest. It's telling Vishal that it's better to spend time with video than with Vonnegut - simply because he's more interested in editing than in reading. Vishal needs needs no other justification for his choice; interest itself is its own acquittal. And we're seeing the same thing in news. While formal learning has been, in the pre-digital world, a matter of rote obligation in the service of intellectual catholicism - and news consumption has been a matter of the bundle rather than the atom - the web-powered world is creating a knowledge economy that spins on the axis of interest. Individual interest. The web inculcates a follow your bliss approach to learning that seeps, slowly, into the broader realm of information; under its influence, our notion of knowledge is slowly shedding its normative layers.

Interactive methods of instruction more valuable than subject matter expertise on the part of the instructor. Study shows that clicker use in a highly interactive instructional setting works better than an experienced lecturer.

A superb science game where player must use their knowledge of the states of matter to play. http://ictmagic.wikispaces.com/science

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

Work That Matters http://t.co/Sjb2vZsWaj Inspired by @AngelaMaiers :) Get your kids work OUT of the bottom of their BACKPACKS! :) #edchat

Most employers do not want employees who hate their work but persist through it anyway. It is a fallacy to believe that we are teaching our kids that the heart of innovative capability (and therefore their future job prospects) is best served by doing something you hate for an extended period of time no matter the consequences.

Great rationale for why networks matter. Peggy Bentlley does a marvelous job of using Tweets to support the points she makes in her blog post. Must read!

"I believe that every single subject taught in high school is a mistake. What I write here will infuriate teachers, but teachers are not my enemy. It isn't their fault. They are cogs in a system over which they have no control. I believe there are many great teachers, and I believe that teaching and teachers are very important."

"Open education" matters because it's already happening all around us. .. although it may not be mainstream yet, it is very real. The models continue to grow and combine with the ethos of open access and the methods of open source.The choice for us, as individuals and educational organisations, is in how we respond.

The quality of our questions, their power to engage and challenge thinking, combined with the opportunities we provide our students to ask the questions that matter to them are likely to be the times when the most powerful learning occurs. The challenge is to maximise these times.
