MEGTUDUNK-E A RELATIVITASELMELETBOL BARMIT IS A TERROL ES AZ IDOROL?

Nem.
Mert
1) igaza Poincarenak, hogy a terrol es idorol tett kijelenteseink nem
a valosag tenyeit fejezik ki, hanem konvencionalisak,
2) mert a Lorentz-elmelet egy letezo, kezenfekvo alternativaja a
relativitaselmeletnek, mikozben a terrol es az idorol egeszen mast mond,
3) mert a relativitaselmelet olyasmit nevez ternek es idonek, amit
jozan esszel eszunk agaban sem lenne ternek es idonek nevezni, s csak
azert nem kerulunk ellentmondasba a fizikai megfigyelesekkel, mert --
Poincare szellemeben szolva -- teljesen mindegy, hogy mit nevezunk
ternek es idonek.

GAME THEORY: ITS AMBITION TO SERVE AS THE FOUNDATION OF THE SOCIAL
SCIENCES AND OF MORAL PHILOSOPHY

Game theory presents itself as the study of collective decision making.
It has however come under frequent attacks on the ground that its
demands for human rationality are overly stringent. It responded to
these challenges vigorously by the imposition of the construct of
evolutionary games. In this talk I suggest to consider, in turn, the
structure of its so-called solution (or equilibrium) concepts. These
concepts can be assessed independently from the norms of rationality
the theory tends to entail. However, as I will argue, none of the
equilibrium concepts leave room for truly interdependent choice and
thus the theory should be seen as unable to address a large range of
issues in the social sciences and in moral philosophy - an
embarrassment given its wide-ranging ambitions. I will demonstrate this
claim by the example of the Prisoner's Dilemma and will especially
consider the extent to which this game can contribute to the discussion
of central issues in moral philosophy.
In the talk, I will present the relevant solution concepts in their
full-fledged mathematical form so that we will be able attend without
hindrance to their conceptual structure.

THE OBSERVER IN QUANTUM MECHANICS

In this talk, we examine the history of the notion of the "observer",
and through this history trace the roots of the current debate over
measurement in Quantum Mechanics.

AZ OKSAG JATSZMAI: IRREVERZIBILITAS ES KONTEXTUALITAS

A newtoni dogma szerint a termeszet torvenyei differencialegyenletek,
amelyekhez esetlegessegkent tarsulnak a kezdeti feltetelek. Ez a
szereposztas neha felrevezeto: a kezdeti feltetelek kozotti valogatas
fontos reszeve valhat a torvenyeknek. Ennek legfontosabb peldaja az
irreverzibilitas, ahol a mikroszkopikus reszletekre - a kontextusra -
vonatkozo kezdofeltetelek valogatasa vezet a makroszkopikus dinamika
melyrehato modosulasahoz.
A kezdeti feltetelektol kulonbozo, de nemikeppen analog, a torveny es
esetlegesseg hataran mozgo szerep juthat a kornyezet altal
meghatarozott sokfele parameternek, amelyek sokszor alapvetoen
modosithatjak a kiragadott reszrendszer viselkedeset. Errol a
kerdeskorrol elozetes olvasmanynak javaslom Giorgio Parisi cikket:
Physica A 263 (1999) 557.
