Rebuking the "Good Old Days"
When you hear someone longing for the "good old days," take it with a grain of salt. (Laughter and applause.) Take it with a grain of salt. We live in a great nation and we are rightly proud of our history. We are beneficiaries of the labor and the grit and the courage of generations who came before. But I guess it's part of human nature, especially in times of change and uncertainty, to want to look backwards and long for some imaginary past when everything worked, and the economy humme...25 MAY 2016 by ideonexus
Political Pragmatism
A reasonable and logical way of doing things or of thinking about problems that is based on dealing with specific situations instead of on ideas and theories. An approach to philosophy, primarily held by American philosophers, which holds that the truth or meaning of a statement is to be measured by its practical (i.e., pragmatic) consequences.

Phonetic Orthography in Spain and Italy
Fonetic spelling, in one form or another, has been,
and is now, used by progressiv teachers in England
and America as an introduction and an aid to the
study of the current orthografy. Their experience is
that children can spel correctly that is, fonetically
the words they ar able to pronounce, as soon as
they hav learnd the alfabet employd, and the principle
of combining letters into sillables.
In languages such as Italian and Spanish, that hav
approximately fonetic alfabets, appro...There is a cost savings that comes with reducing the number of years spent teaching spelling.

The ITER Project
Years from now—maybe in a decade, maybe sooner—if all goes according to plan, the most complex machine ever built will be switched on in an Alpine forest in the South of France. The machine, called the International Thermonuclear Experimental Reactor, or iter, will stand a hundred feet tall, and it will weigh twenty-three thousand tons—more than twice the weight of the Eiffel Tower. At its core, densely packed high-precision equipment will encase a cavernous vacuum chamber, in which a s...Description of a multi-national effort to produce a fusion reactor. Something some refer to as a "non-optional" technology for the human race to survive.

Gompertz Law of human mortality
What do you think are the odds that you will die during the next year? Try to put a number to it — 1 in 100? 1 in 10,000? Whatever it is, it will be twice as large 8 years from now.
This startling fact was first noticed by the British actuary Benjamin Gompertz in 1825 and is now called the “Gompertz Law of human mortality.” Your probability of dying during a given year doubles every 8 years. For me, a 25-year-old American, the probability of dying during the next year is a fairly ...Folksonomies: statistics mortality

Conservation Tasks and Reason
Piaget had his own way of assessing brain maturation during this period, using his now-famous "conservation" tasks, try this one out on your tour-to-eight-year-old: fill two identical short, squat glasses with equal volumes of water, and ask your child, "Do the two glasses contain the same amount of water, or does one have more?" Now, pour all the water from one of these 'lasses into a tall, narrow glass, and ask your child the same question.
Four-year-olds almost invariably say that the ta...A four-year-old cannot grasp the concept of conservation of mass, but an eight-year-old has no problem with it.
