Border Crossings into Science Culture
Learning to communicate in and with a culture of science is a much broader undertaking than mastering a body of discrete conceptual or procedural knowledge. One observer, for example, describes the process of science education as one in which learners must engage in "border crossings" from their own everyday world culture into the subculture of science.^ The subculture of science is in part distinct from other cultural activities and in part a reflection of the cultural backgrounds of scienti...19 MAR 2015 by ideonexus
The Umwelt Bubble
The biologist Jakob von Uexküll’s term Umwelt refers to a concept about the subjective world of an organism. The world can be imagined as a soap bubble, which surrounds each individual and contains signifying markers relevant only to the world of that specific creature. This soap bubble, or Umwelt, is actively created by the individual organism in a process of forming a perception of reality, which is guided by the organism’s design, its physiology, and its needs. According to Uexküll,...Folksonomies: perception transhumanism

Reflection is Destructive
So long as scientists and philosophers remain a caste, even the problem of morality, that is, of behaviour, will remain for them one of cognition and not of activity, a subject for study and not for practical application, something that just happens rather than something that must be done and, furthermore, done not by individuals but collectively. So long as scholars are not prepared to become a Commission for the elaboration of a plan of common action (and without this mankind cannot act a...21 APR 2014 by ideonexus
Five Strands of Mathematical Literacy
Recognizing that no term captures completely all aspects of expertise, competence, knowledge, and facility in mathematics, we have chosen mathematical proficiency to capture what we think it means for anyone to learn mathematicssuccessfully. Mathematical proficiency, as we see it, has five strands: • conceptual understanding—comprehension of mathematical concepts, operations, and relations • procedural fluency—skill in carrying out procedures flexibly, accurately, efficiently, and a...Folksonomies: education mathematics

The Three Principal Means of Investigation
We have three principal means: observation of nature, reflection, and experiment. Observation gathers the facts, reflection combines them, experiment verifies the result of the combination. It is essential that the observation of nature be assiduous, that reflection be profound, and that experimentation be exact. Rarely does one see these abilities in combination. And so, creative geniuses are not common.Each is a virtue, and strength in all three is rare.

Levels of Simulation
Such is simulation, insofar as it is opposed to representation. Representation stems from the principle of the equivalence of the sign and of the real (even if this equivalence is Utopian, it is a fundamental axiom). Simulation, on the contrary, stems from the Utopia of the principle of equivalence, from the radical negation of the sign as value, from the sign as the reversion and death sentence of every reference. Whereas representation attempts to absorb simulation by interpreting it as a f...The differences between appearance and simulation.

Life is Rebellion Against Chaos
Life is order, death is disorder. A fundamental law of Nature states that spontaneous chemical changes in the universe tend toward chaos. But life has, during milliards of years of evolution, seemingly contradicted this law. With the aid of energy derived from the sun it has built up the most complicated systems to be found in the universe—living organisms. Living matter is characterized by a high degree of chemical organisation on all levels, from the organs of large organisms to the small...Folksonomies: complexity chaos

Argument for Decimal Currency
[Decimal currency is desirable because] by that means all calculations of interest, exchange, insurance, and the like are rendered much more simple and accurate, and, of course, more within the power of the great mass of people. Whenever such things require much labor, time, and reflection, the greater number who do not know, are made the dupes of the lesser number who do.Because it is simple and complex things lead to people being taken advantage of.

Species Go Through the Same Stages as Individual Living B...
Just as in the animal and vegetable kingdoms, an individual comes into being, so to speak, grows, remains in being, declines and passes on, will it not be the same for entire species? If our faith did not teach us that animals left the Creator's hands just as they now appear and, if it were permitted to entertain the slightest doubt as to their beginning and their end, may not a philosopher, left to his own conjectures, suspect that, from time immemorial, animal life had its own constituent e...Folksonomies: religion philosophy

Observation, Reflection, and Experimentation
We have three approaches at our disposal: the observation of nature, reflection, and experimentation. Observation serves to assemble the data, reflection to synthesise them and experimentation to test the results of the synthesis. The observation of nature must be assiduous, just as reflection must be profound, and experimentation accurate. These three approaches are rarely found together, which explains why creative geniuses are so rare.Folksonomies: scientific method genius
