Hawking Considers Computer Viruses Life
A living being like you or me usually has two elements: a set of instructions that tell the system how to keep going and how to reproduce itself, and a mechanism to carry out the instructions. In biology, these two parts are called genes and metabolism. But it is worth emphasising that there need be nothing biological about them. For example, a computer virus is a program that will make copies of itself in the memory of a computer, and will transfer itself to other computers. Thus it fits the...Folksonomies: life

Children are Smarter Than Adults
This precocity of childhood may be said to characterise all the known races of man, and to be even more marked the more primitive the race. On this point, ‘It is an interesting fact,’ says Havelock Ellis (183, p. 177), ‘and perhaps of some significance, that among primitive races in all parts of the world, the children, at an early age, are very precocious in intelligence.’ And again, ‘ It seems that, the lower the race, the more marked is this precocity, and its arrest at puberty. ... 1 notes

Fluid Intelligence has Made the Most Gains
So which kinds of intellectual performance have been pushed upward by the better environments of recent decades? Surprisingly, the steepest gains have not been found in the concrete skills that are directly taught in school, such as general knowledge, arithmetic, and vocabulary. They have been found in the abstract, fluid kinds of intelligence, the ones tapped by similarity questions (“What do an hour and a year have in common?”), analogies (“BIRD is to EGG as TREE is to what?”), and ...Folksonomies: intelligence iq

Negative Attention is Better Than No Attention at All
To give and receive attention is a fundamental human need. In the 13th century, King Frederick II of Sicily wanted to find out what language children would naturally grow up to speak if they were never spoken to. He took babies from their mothers at birth and placed them in the care of nurses who were strictly forbidden to either speak to or touch them. The babies, as it turned out, didn’t grow up to speak any language, as they all died of attention deprivation within a fortnight of the sta... 1 notes

Scientists in New Atlantis
"These are (my son) the riches of Salomon's House.
"For the several employments and offices of our fellows; we have twelve that sail into foreign countries, under the names of other nations, (for our own we conceal); who bring us the books, and abstracts, and patterns of experiments of all other parts. These we call Merchants of Light.
"We have three that collect the experiments which are in all books. These we call Depredators.
"We have three that collect the experiments of all mechanical...

With the Seed We May Deduce the Animal
If we possessed a thorough knowledge of all the parts of the seed of any animal (e.g. man), we could from that alone, by reasons entirely mathematical and certain, deduce the whole conformation and figure of each of its members, and, conversely if we knew several peculiarities of this conformation, we would from those deduce the nature of its seed. 1 notes
notesInteresting idea, if wrong for not understanding how environment affects growth, but the idea that we could one day take a seed and predict the full-grown organism that will result from it is intriguing.

Overconfidence Breeds Error
In one classic demonstration,
clinical psychologists were asked to give
confidence judgments on a personality
profile. They were given a case report in
four parts, based on an actual clinical
case, and asked after each part to answer
a series of questions about the patient’s
personality, such as his behavioral
patterns, interests, and typical reactions to
life events. They were also asked to rate
their confidence in their responses. With
each section, background information
about the case i... 1 notes
notesThe more a person knows about a subject, the more likely they are to make mistakes in judgement.

Newton's Definitions
Def. I.
The Quantity of Matter is the measure of the same, arising from its density and bulk conjunctly.
THUS AIR of a double density, in a double space, is quadruple in quantity; in a triple space, sextuple in quantity. The same thing is to be understood of snow, and fine dust or powders, that are condensed by compression or liquefaction; and of all bodies that are by any causes whatever differently condensed. I have no regard in this place to a medium, if any such there is, that freely pe...Hints of conservation of mass and velocity.

Empiricism in Buddhist Spirituality
Both Buddhism and neuroscience converge on a similar point of view: The way it feels isn’t how it is. There is no permanent, constant soul in the background. Even our language about ourselves is to be distrusted (requiring the tortured negation of anatta). In the broadest strokes then, neuroscience and Buddhism agree.
How did Buddhism get so much right? I speak here as an outsider, but it seems to me that Buddhism started with a bit of empiricism. Perhaps the founders of Buddhism were pre-... 1 notes
notesBuddhists recognize the impermanence of human existence, that we are perpetually changing. They discovered this truth, shared with neuroscience, because they gave up the ego of the self.

One Half of DNA is Parasitic
Parasites are not only incredibly diverse; they are also incredibly successful. There are parasitic stretches of DNA in your own genes, some of which are called retrotransposons. Many of the parasitic stretches were originally viruses that entered our DNA. Most of them don't do us any harm. They just copy and insert themselves in other parts of our DNA, basically replicating themselves. Sometimes they hop into other species and replicate themselves in a new host. According to one estimate, ro... 1 notes
notesThis doesn't sound right to me, but the claim is that Viruses have inserted so much DNA into our genomes.
