    Every object in the Universe attracts every other object with a force directed along the line of centers for the two objects that is proportional to the product of their masses and inversely proportional to the square of the separation between the two objects.

  • It has taken years of acclimatizing our youth to stale artificial environments, piles of propaganda convincing them that what goes on inside these environments is of immense importance, and a steady hand of discipline should they ever start to question it.

      There is a huge investment in resources, time, and tradition from the teacher, the instutions, the society, and--importantly--the students. Students have invested much more time (proportional to their short lives) in learning how to be skillful at the education game. Many don't like teachers changing the rules of the game just when they've become proficient at it.
  • Last spring I asked my students how many of them did not like school. Over half of them rose their hands. When I asked how many of them did not like learning, no hands were raised. I have tried this with faculty and get similar results. Last year’s U.S. Professor of the Year, Chris Sorensen, began his acceptance speech by announcing, “I hate school.” The crowd, made up largely of other outstanding faculty, overwhelmingly agreed. And yet he went on to speak with passionate conviction about his love of learning and the desire to spread that love. And there’s the rub. We love learning. We hate school. What’s worse is that many of us hate school because we love learning.

      So we (teachers and students) are willing to endure a little (or a lot) of uncomfortableness in order to pursue that love of learning.
  • They tell us, first of all, that despite appearances, our classrooms have been fundamentally changed.
  • ...6 more annotations...
  • While most of our classrooms were built under the assumption that information is scarce and hard to find, nearly the entire body of human knowledge now flows through and around these rooms in one form or another, ready to be accessed by laptops, cellphones, and iPods. Classrooms built to re-enforce the top-down authoritative knowledge of the teacher are now enveloped by a cloud of ubiquitous digital information where knowledge is made, not found, and authority is continuously negotiated through discussion and participation. In short, they tell us that our walls no longer mark the boundaries of our classrooms.
  • And that’s what has been wrong all along. Some time ago we started taking our walls too seriously – not just the walls of our classrooms, but also the metaphorical walls that we have constructed around our “subjects,” “disciplines,” and “courses.” McLuhan’s statement about the bewildered child confronting “the education establishment where information is scarce but ordered and structured by fragmented, classified patterns, subjects, and schedules” still holds true in most classrooms today. The walls have become so prominent that they are even reflected in our language, so that today there is something called “the real world” which is foreign and set apart from our schools. When somebody asks a question that seems irrelevant to this real world, we say that it is “merely academic.”
  • We can use them in ways that empower and engage students in real world problems and activities, leveraging the enormous potentials of the digital media environment that now surrounds us. In the process, we allow students to develop much-needed skills in navigating and harnessing this new media environment, including the wisdom to know when to turn it off. When students are engaged in projects that are meaningful and important to them, and that make them feel meaningful and important, they will enthusiastically turn off their cellphones and laptops to grapple with the most difficult texts and take on the most rigorous tasks.
  • At the root of your question is a much more interesting observation that many of the styles of self-directed learning now enabled through technology are in conflict with the traditional teacher-student relationship. I don’t think the answer is to annihilate that relationship, but to rethink it.
  • Personally, I increasingly position myself as the manager of a learning environment in which I also take part in the learning. This can only happen by addressing real and relevant problems and questions for which I do not know the answers. That’s the fun of it. We become collaborators, with me exploring the world right along with my students.
  • our walls, the particular architectonics of the disciplines we work within, provide students with the conversational, narrative, cognitive, epistemological, methodological, ontological, the –ogical means for converting mere information into knowledge.

  • Advise the Advisor is a new program to help senior staff at the White House stay connected to the American people.

    Providing our nation’s students with a world-class education is a shared responsibility. It’s going to take all of us – teachers, parents, students, philanthropists, state and local governments, and the federal government – working together to prepare today’s students for the future.

    This week, Melody Barnes, Director of the Domestic Policy Council and one of President Obama’s senior advisors on education policy, is asking for feedback from parents, teachers and students about what’s working in their communities and what needs to change when it comes to education.

    You can add your voice to the conversation by answering one or all of the following questions:

    • Parents: Responsibility for our children’s education and future begins in our homes and communities. What are some of the most effective ways you're taking responsibility at a personal and local level for your child’s education?
    • Teachers: President Obama has set a goal of having the highest proportion of college graduates in the world by 2020. How are you preparing your students for college and career? What’s working and what challenges do you face?
    • Students: In order to compete for the jobs of the 21st century, America’s students must be prepared with a strong background in reading, math and science along with the critical thinking, problem solving, and creativity needed to succeed in tomorrow’s workforce. How has your education prepared you for a career in the 21st century? What has worked and what challenges do you face?

    Past Questions

    David Plouffe, Senior Advisor to the President, kicked off the series by asked for your feedback on how American innovation affects your community and the obstacles to innovation you see where you live. Check out David’s video and read his follow up blog post responding to some of the major themes we saw in reading your feedback.

    Austan Goolsbee, Chairman of the Council of Economic Advisors, posted the second edition of Advise the Advisor asking for feedback from small businesses about the obstacles they face in getting off the ground. Austan responded to some of your feedback during a live chat at the Winning the Future Forum on Small Business in Cleveland.

    Please answer the question(s) below that best apply to you. Please restrict your answers to no more than 2,500 characters.

Atmospheric Permanent Magnet Variable Frequency Screw Air Compressor - 2 views

    Atmospheric Permanent Magnet Variable Frequency Screw Air Compressor The rotation speed of the air compressor motor is proportional to the actual power consumption, so the rotation speed reduction of the motor will decrease the actual power consumption on a year-on-year basis. The permanent magnet screw compressor uses a pressure sensor to sense the actual pressure and air consumption in the system, further realizes the precise control of the electrical equipment and frequency converter; it changes the rotation speed of the micro screw compressor without changing the torque of the air compressor motor, thus adjusts the system pressure to achieve the desired output of compressed air. When the air consumption decreases and the compressed air provided by the air compressor is greater than the air consumption, the permanent magnet variable frequency air compressor will reduce the speed, thus the output of compressed air is reduced; Otherwise, the motor speed will be increased to add the compressed air, so as to maintain a stable pressure.

    Although the proportion of food thickening powder added to food is not large, it can effectively improve the quality and performance of food. It can not only thicken food, but also have the functions of stabilizer, emulsifier, film-forming agent, gelling agent, suspending agent, foaming agent, etc., so it is widely used in the food industry.
