O intrebare basic, careia i s-a gasit raspunsul acum 100 de ani, continua sa mai mire (normal, daca se folosesc expresii tip "nonlocalism" sau "in mai multe locuri deodata") si sa necesite noi demonstratii

Eu cred ca nu este vorba decat de interferenta cu aparatura de masurare combinata cu metodele noastre imature ...

Nu e vorba aici de a crede.
E vorba numai de a interpreta niste relatii matematice care arata fara echivoc (si la asta se refera rezultatele sirului tot mai sofistcat de experiente) ca realitatea nu este clasica, ca nu se potriveste cu intuitia noastra evoluata intr-un mediu clasic.
Interpretarea se refera la a alege intre nerealism local sau realism nelocal. Realismul local (clasicismul) este refutat din 1920.

According to the interpretation, the interaction of an observer or apparatus that is external to the quantum system is the cause of wave function collapse, thus according to Heisenberg "reality is in the observations, not in the electron"

"Early humans went from having trees available to having only grasses available in just 10 to 100 generations, and their diets would have had to change in response," he said. "Changes in food availability, food type, or the way you get food can trigger evolutionary mechanisms to deal with those changes. The result can be increased brain size and cognition, changes in locomotion and even social changes -- how you interact with others in a group. Our data are consistent with these hypotheses. We show that the environment changed dramatically over a short time, and this variability coincides with an important period in our human evolution when the genus Homo was first established and when there was first evidence of tool use."

Israel's Antiquities Authority (IAA) has announced that archeologists have unearthed a temple within walking distance of Jerusalem that appears to be approximately 2,750 years old. Artifacts found inside the temple suggest that despite the ban on idol worship at the time, those who visited the temple continued to engage in such practices. The temple was discovered as part of a dig at a site known as Tel Motza, after the city of Mozah mentioned in the Old Testament.

Most people will share anonymously, but they share even more when they aren't anonymous. Bonobos won't share at all in the anonymous condition if it costs them food.
"They care about others," Hare said, but only in a sort of selfish way. "They'll share when it's a low-cost/low-benefit kind of situation. But when it's a no-benefit situation, they won't share. That's different from a human playing the dictator game. You really have to care about others to give anonymously."

Interesant este ca fizicienii de la Copenhaga au vazut lucrurile in mod diferit. Practic, interpretarea de la Copenhaga sunt doua (a lui Bohr - cu care sunt absolut de acord - si a lui Heisenberg), total divergente.

http://plato.stanfor.../qm-copenhagen/
In a very recent study Ravi Gomatam (2007) agrees with Howard's exposition in arguing that Bohr's interpretation of complementarity and the textbook Copenhagen interpretation (i.e. wave-particle duality and wave packet collapse) are incompatible.

Articolul de pe wikipedia este contradictoriu: Heisenberg never used the term collapse, preferring to speak of the wavefunction representing our knowledge of a system.
Cunostintele noastre colapseaza, deci, asta este interpretarea unitara

Reformulez corect: According to the interpretation, the interaction of an observer or apparatus that is external to the quantum system is the cause of wave function collapse, thus according to Heisenberg "~~reality~~ knowledge is in the observations, not in the electron".

Omul s-a referit prin "reality" la ceea ce cunoastem noi ca fiind realitate. Practica in prima fraza autorul numeste colapsul functiei de unda ca fiind colapsul cunoasterii noastre. :-)
Eu persona consider ca interpretarea Broglie-Bohm este mai apropiata de realitatea fizica. Functia de unda reprezinta o vibratie in alta dimensiune fizica.

Chimpanzees Successfully Play the Ultimatum Game: Apes' Sense of Fairness Confirmed

Quote

Humans typically offer generous portions, such as 50 percent of the reward, to their partners, and that's exactly what we recorded in our study with chimpanzees.

Childhood Trauma Leaves Its Mark On the Brain

Quote

It is well known that violent adults often have a history of childhood psychological trauma. Some of these individuals exhibit very real, physical alterations in a part of the brain called the orbitofrontal cortex. Yet a direct link between such early trauma and neurological changes has been difficult to find, until now.
................
we noticed that there was very little activation of the orbitofrontal cortex. This, in turn, reduces their ability to moderate their negative impulses. This reduced activation is accompanied by the overactivation of the amygdala, a region of the brain that's involved in emotional reactions.
........
We found that the level of MAOA gene expression increased in the prefrontal cortex,"

Nu te condamn pentru asta, din acest poll rezulta ca 58% dintre fizicieni nu inteleg, desi au trecut de atunci aproape 100 de ani, cea mai importanta descoperire din secolul 20 si cea mai drastica schimbare de paradigma din istoria stiintei (dupa mine chiar mai drastica decat teoria evolutiei).

Bravo. Si tu zici ca te situezi in procentajul de 6%, nu? Nu ti se pare cam mic?

Neurochirurgie minim invazivă

"Primum non nocere" este ideea ce a deschis drumul medicinei spre minim invaziv.

Avansul tehnologic extraordinar din ultimele decenii a permis dezvoltarea tuturor domeniilor medicinei. Microscopul operator, neuronavigația, tehnicile anestezice avansate permit intervenții chirurgicale tot mai precise, tot mai sigure. Neurochirurgia minim invazivă, sau prin "gaura cheii", oferă pacienților posibilitatea de a se opera cu riscuri minime, fie ele neurologice, infecțioase, medicale sau estetice.
