Even more difficult to explain, than the breaking-up of a single mass into fragments, and the drifting apart of these blocks to form the foundations of the present-day continents, is the explanation of the original production of the single mass, or PANGAEA, by the concentration of the former holosphere of granitic…
My mind seems to have become a kind of machine for grinding general laws out of large collections of facts, but why this should have caused the atrophy of that part of the brain that alone on which the higher tastes depend, I cannot conceive. A man with a mind more highly organised or better constituted than mine…
As buds give rise by growth to fresh buds, and these, if vigorous, branch out and overtop on all sides many a feebler branch, so by generation I believe it has been with the great Tree of Life, which fills with its dead and broken branches the crust of the earth, and covers the surface with its ever branching and…
In a thoughtful mood Davy wrote a new kind of metaphysical poem, ‘The Massy Pillars of the Earth. It reflects on the human condition, and suggests that since nothing is ever destroyed in the physical universe, only transformed (the First Law of Thermodynamics), then man himself must be immortal in some spiritual…
Scientists are also encouraged by studies on mice with a certain genetic mutation that makes them age prematurely — complete with graying and thinning fur, cataracts, hearing loss, smaller brains, enlarged hearts, anemia and thin and weak muscles — hallmark symptoms of growing older. To test whether it was possible to…
• Motor neurons die, particularly from age 60 onward. This causes connections between muscle fibers to wither — and that, in turn, eventually leads to loss and shrinking of muscle fibers. As a result, muscles get smaller and a person gets weaker, says Sandra Hunter, an associate professor of exercise science at…
This rise in pediatric obesity is painful to hear in the brain science community, especially because we know so much about the relationship between physical activity and mental acuity. Exercise—especially aerobic exercise—is fanastic for the brain, increasing executive function scores anywhere from 50 percent to 100…
IQ is malleable. IQ has been shown to vary over one’s life span, and it is surprisingly vulnerable to environmental influences. It can change if one is stressed, old, or living in a different culture from the testing majority. A child’s IQ is influenced by his or her family, too. Growing up in the same household tends…
Many films diminish us. They cheapen us, masturbate our senses, hammer us with shabby thrills, diminish the value of life. Some few films evoke the wonderment of life's experience, and those I consider a form of prayer. Not prayer "to" anyone or anything, but prayer "about" everyone and everything. I believe prayer…
To be happy in old age it is necessary that we accustom ourselves to objects that can accompany the mind all the way through life, and that we take the rest as good in their day. The mere man of pleasure is miserable in old age; and the mere drudge in business is but little better: whereas, natural philosophy…
