 Habituation and Novelty

Beginning in infancy and throughout the life span, humans are motivated by newness, change, and excitement. Habituation, the tendency to lose interest in a repeated event and gain interest in a new one, is one of the most fundamental human reflexes. If the thermostat were to suddenly turn the air conditioning on, you would hear the loud humming sound begin, but within minutes you couldn’t even hear it if you tried. Habituation, a fundamental property of the nervous system, provides mechanis...

 An Alien United Nations

figure out how to live with high technology, how to avoid nuclear war, then tehre are at this moment a million advanced civilizations in the Milky Way. This place was built to help get us through this dangerous time. it would be good to know if there are other civilizations out there, if their United Nations have succeeded. it's something to think about when you stare up at the stars on a clear autumn night.

 Chemistry as the Foundation of Science

Chemistry I deem to be the foundation of all other science, and in a manner pf speaking to comprise all other branches of science. As matter and motion comprise everything we can behold or conceive, and as Chemistry is an investigation of the properties of matter, with the causes and effects of its various combinations, it is evidently the most important part of science, or rather, the first and last part of it. The cultivation of the earth—the cookery of our food—its quantity and quality...

 We Should Think of Ourselves as Atoms

we should consider ourselves but as atoms of organized matter, whose pleasure or whose pain, whose existence in a state of organization, or whose non-existence in that state, is a matter of no importance in the laws and operations of Nature; we should view ourselves with the same feelings, as we view the leaf which rises in the spring, and falls in the autumn, and then serves no further purpose but to fertilize the earth for a fresh production; we should view ourselves but as the blossoms of ...

 The Talent of Mechanics

Generally speaking, people have a very erroneous idea of the type of talent proper to the ideal mechanician. He is not a geometrician who, delving into the theory of movement and the categories of phenomena, formulates new mechanical principles or discovers unsuspected laws of nature.… In most other branches of science are to be found constant principles; a multitude of methods offer to the genius inexhaustible possibilities. If a scholar poses himself a new problem, he can attack it fortif...

 Prejudice is an Enemy of Reason

We shall expose the origin and trace the history of general errors, which have more or less contributed to retard or suspend the advance of reason, and sometimes even, as much as political events, have been the cause of man’s taking a retrograde course towards ignorance. Those operations of the mind that lead to or retain us in error, from the subtle paralogism, by which the most penetrating mind may be deceived, to the mad reveries of enthusiasts, belong equally, with that just mode of re...

 Research Conquers our Ignorance

Hard problems often yield before science, and though we still don’t understand how every complex biochemical system evolved, we are learning more every day. After all, biochemical evolution is a field in still its infancy. If the history of science teaches us anything, it is that what conquers our ignorance is research, not giving up and attributing our ignorance to the miraculous work of a creator. When you hear someone claim otherwise, just remember these words of Darwin: “Ignorance mor...

 Piaget's View on Child Learning

Piaget concluded that babies aren't just born in possession of adult knowledge, either from a past life or from DNA. Instead, Piaget thought that children must have powerful learning mechanisms that allow them to construct new pictures of the world, pictures that might be very different from the adult picture. When we learn about the world, when we do science. for example, we don't just hit the right answer once and for all. Rather, there is a very gradual unfolding sequence of corrected erro...
