Einstein's theory of relativity - 0 views

  •  
    Here is a great summary of the theory of relativity and my favorite part is at the end where it leaves room and even suggests that such a theory implies the existence of a creator.

  • These theories, however, were developed in a time when learning was not impacted through technology.
  • In many fields the life of knowledge is now measured in months and years.

  • The amount of knowledge in the world has doubled in the past 10 years and is doubling every 18 months according to the American Society of Training and Documentation (ASTD). To combat the shrinking half-life of knowledge, organizations have been forced to develop new methods of deploying instruction.
  • Technology is altering (rewiring) our brains. The tools we use define and shape our thinking
  • learning as a lasting changed state (emotional, mental, physiological (i.e. skills)) brought about as a result of experiences and interactions with content or other people.
  • Objectivism (similar to behaviorism) states that reality is external and is objective, and knowledge is gained through experiences. Pragmatism (similar to cognitivism) states that reality is interpreted, and knowledge is negotiated through experience and thinking. Interpretivism (similar to constructivism) states that reality is internal, and knowledge is constructed.
  • Behaviorism states that learning is largely unknowable, that is, we can’t possibly understand what goes on inside a person (the “black box theory”)
  • Cognitivism often takes a computer information processing model. Learning is viewed as a process of inputs, managed in short term memory, and coded for long-term recall.
  • Constructivism suggests that learners create knowledge as they attempt to understand their experiences
  • Constructivism assumes that learners are not empty vessels to be filled with knowledge. Instead, learners are actively attempting to create meaning. Learners often select and pursue their own learning. Constructivist principles acknowledge that real-life learning is messy and complex.
  • learning that occurs outside of people
  • The ability to synthesize and recognize connections and patterns is a valuable skill.
  • In today’s environment, action is often needed without personal learning – that is, we need to act by drawing information outside of our primary knowledge.
  • An entirely new approach is needed.
  • How can we continue to stay current in a rapidly evolving information ecology?
  • We can no longer personally experience and acquire learning that we need to act. We derive our competence from forming connections.
  • Unlike constructivism, which states that learners attempt to foster understanding by meaning making tasks, chaos states that the meaning exists – the learner's challenge is to recognize the patterns which appear to be hidden
  • The capacity to form connections between sources of information, and thereby create useful information patterns, is required to learn in our knowledge economy.
  • A network can simply be defined as connections between entities.
  • Nodes that successfully acquire greater profile will be more successful at acquiring additional connections
  • Finding a new job, as an example, often occurs through weak ties. This principle has great merit in the notion of serendipity, innovation, and creativity. Connections between disparate ideas and fields can create new innovations.
  • Connectivism is the integration of principles explored by chaos, network, and complexity and self-organization theories.
  • Learning and knowledge rests in diversity of opinions.
  • Decision-making is itself a learning process. Choosing what to learn and the meaning of incoming information is seen through the lens of a shifting reality. While there is a right answer now, it may be wrong tomorrow due to alterations in the information climate affecting the decision.
  • The starting point of connectivism is the individual.
  • This cycle of knowledge development (personal to network to organization) allows learners to remain current in their field through the connections they have formed.
  • the internet leverages the small efforts of many with the large efforts of few.
  • example of a Maricopa County Community College system project that links senior citizens with elementary school students in a mentor program. The children “listen to these “grandparents” better than they do their own parents, the mentoring really helps the teachers…the small efforts of the many- the seniors – complement the large efforts of the few – the teachers.” (2002). This amplification of learning, knowledge and understanding through the extension of a personal network is the epitome of connectivism.
  • Implications
  • The pipe is more important than the content within the pipe. Our ability to learn what we need for tomorrow is more important than what we know today. A real challenge for any learning theory is to actuate known knowledge at the point of application.
  • acknowledges the tectonic shifts in society where learning is no longer an internal, individualistic activity

Einstein's theory of relativity explained with four letter words (or smaller). - 0 views

  •  
    This is a great summary of how the theory actually works and it is done using small words (four letters or less). and it brings in a lot of the history of it all, including newton and aristotle's theories and how they were broken.

Differences Between Classical & Keynesian Economics | Small Business - Chron.com - 0 views

  • Two economic schools of thought are classical and Keynesian. Each school takes a different approach to the economic study of monetary policy, consumer behavior and government spending. A few basic distinctions separate these two schools.
  • Classical economic theory is rooted in the concept of a laissez-faire economic market. A laissez-faire--also known as free--market requires little to no government intervention. It also allows individuals to act according to their own self interest regarding economic decisions.
  • Keynesian economic theory relies on spending and aggregate demand to define the economic marketplace. Keynesian economists believe the aggregate demand is often influenced by public and private decisions. Public decisions represent government agencies and municipalities. Private decisions include individuals and businesses in the economic marketplace. Keynesian economic theory relies heavily on the fact that a nation’s monetary policy can affect a company’s economy.

  • Government spending is not a major force in a classical economic theory.
  • Too much government spending takes away valuable economic resources needed by individuals and businesses. To classical economists, government spending and involvement can retard a nation’s economic growth by increasing the public sector and decreasing the private sector. Keynesian economics relies on government spending to jumpstart a nation’s economic growth during sluggish economic downturns.
  • Classical economics focuses on creating long-term solutions for economic problems.
  • Keynesian economics often focuses on immediate results in economic theories. Policies focus on the short-term needs and how economic policies can make instant corrections to a nation’s economy. This is why government spending is such a key cog of Keynesian economics.

The Business Cycle: Krugman vs. Austrian Economic Theory - 0 views

  • Stimulus payments to consumers is analogous to dumping frosting onto a cake mix, before the ingredients have been mixed and baked. All elements of the economy, from raw materials, to intermediate goods, to consumer goods, must return to a supply-demand balance before the economy can gain Krugman’s “traction.” That necessarily takes time, because mining companies and other producers of basic raw materials have time scales for increased output and employment that are very different from the time scales of intermediate goods producers and consumer goods manufacturers.
  • Keynesian economics, as expounded by New York Times columnist Paul Krugman, is essentially a black box theory. Stand on the outside of the economic box and dump into it endless baskets of inflationary fiat money, and things supposedly just happen automatically inside the black box to produce permanent prosperity and near zero unemployment.

  • No one can draw any clear distinction between individual differences and slight varieties; or between more plainly marked varieties and subspecies, and species.
  • why should we doubt that variations in any way useful to beings, under their excessively complex relations of life, would be preserved, accumulated, and inherited?

      Progression, in species rather than individual people.
  • The theory of natural selection, even if we looked no further than this, seems to me to be in itself probable. I have already recapitulated, as fairly as I could, the opposed difficulties and objections: now let us turn to the special facts and arguments in favour of the theory.
    • Erin Hamson
       
      It seems perfectly logical.
  • On the view that species are only strongly marked and permanent varieties, and that each species first existed as a variety, we can see why it is that no line of demarcation can be drawn between species, commonly supposed to have been produced by special acts of creation, and varieties which are acknowledged to have been produced by secondary laws. On this same view we can understand how it is that in each region where many species of a genus have been produced, and where they now flourish, these same species should present many varieties; for where the manufactory of species has been active, we might expect, as a general rule, to find it still in action; and this is the case if varieties be incipient species.
    • Erin Hamson
       
      Starting with the premise that species came from one, ie "first existed as a variety", if they were each distinctly created, then this logic is false, because the premise is false. 
  • preserve the most divergent offspring
  • Hence during a long-continued course of modification, the slight differences, characteristic of varieties of the same species, tend to be augmented into the greater differences characteristic of species of the same genus.
    • Erin Hamson
       
      How species come about.
  • New and improved varieties will inevitably supplant and exterminate the older, less improved and intermediate varieties; and thus species are rendered to a large extent defined and distinct objects.

      Extinction
  • This grand fact of the grouping of all organic beings seems to me utterly inexplicable on the theory of creation.
    • Erin Hamson
       
      The fact that there are relations among different species. 
  • But why this should be a law of nature if each species has been independently created, no man can explain.
  • As natural selection acts solely by accumulating slight, successive, favourable variations, it can produce no great or sudden modification; it can act only by very short and slow steps
    • Erin Hamson
       
      Where is the evidence for these short steps? 
  • The wonder indeed is, on the theory of natural selection, that more cases of the want of absolute perfection have not been observed.
  • As natural selection acts by competition, it adapts the inhabitants of each country only in relation to the degree of perfection of their associates;

Coase's Penguin: Or, Linux and The Nature of the Firm - 0 views

  • I suggest that we are seeing is the broad and deep emergence of a new, third mode of production in the digitally networked environment. I call this mode "commons-based peer-production," to distinguish it from the property- and contract-based models of firms and markets. Its central characteristic is that groups of individuals successfully collaborate on large-scale projects following a diverse cluster of motivational drives and social signals, rather than either market prices or managerial commands.

Theories of Religion in Early 20th Century Psychology@Everything2.com - 0 views

  • Freud believed humanity is moving through three stages of development: Tribal, Religious, Scientific.  He believed society would eventually cast off the unnecessary and unfounded ideals of religion in trade for the exactitudes and truth offered by the scientific method.
  • Unlike Sigmund Freud, who believed religion to be an illusory wish fulfillment for the weak minded, Carl Jung advocated religion as an indispensable part of an individual's psychological development. Jung viewed the mind as having three components: the ego, the personal unconscious, and the collective unconscious. Freud's vision of the mind did not include a collective unconscious. Instead, Freud proposed a moral super-ego, which grew to become the mind's administrator according to a learned sense of morality. Jung believed the self-actualizing properties of Freud's super ego pre-exist in the mind as a collective unconscious which is to be discovered through introspection as opposed to learned from experience.
