Struggles with the Continuum
نویسنده
چکیده
Is spacetime really a continuum, with points being described—at least locally— by lists of real numbers? Or is this description, though immensely successful so far, just an approximation that breaks down at short distances? Rather than trying to answer this hard question, let’s look back at the struggles with the continuum that mathematicians and physicists have had so far. The worries go back at least to Zeno. Among other things, he argued that that an arrow can never reach its target:

Commanding Good and Forbidding Evil; a Theoretical Solution for Struggles against Shah's Regime from Imam Khomeini's Viewpoint
Imam Khomeini's struggle against Pahlavi's regime was founded on numerous jurisprudential bases, an important one of which is commanding good and forbidding evil. In this article, first the jurisprudential explanation of commanding good and forbidding evil from Imam Khomeini's viewpoint has been offered and then, a historic-analytic approach has been applied to find examples in his stances from...
متن کاملEstimating the continuum of quasars using the articial neural networks
A lot of absorption lines are in the bluewards of Lyα emission line of quasar which is well-known as Lyαforest. Most of absorption lines in this forest belong to the Lyα absorption of the neutral hydrogen in the inter-galactic medium (IGM). For high redshift quasars and in the continuum with low and medium resolution, there are no many regions without absorption, so that, the quasar continuum i...
متن کاملA Continuum Model For Stone-wales Defected Carbon Nanotubes
In this paper, a continuum model is proposed so that a Stone-Wales (SW) defected carbon nanotube (CNT) is replaced by an initial circumferential crack in a continuum cylindrical shell. For this purpose, the critical energy release rate and then the fracture toughness of a defected CNT are calculated using the results of an existing atomistic-based continuum finite element simulation. Finally, t...
متن کاملInelastic Continuum Modeling of Carbon Nanotube,s Behavior Using Finite Element Method
This paper describes a continuum model for analyzing the inelastic behavior of a single walled carbon nanotube (SWCNT) in different loading conditions. Because of limitations in using molecular dynamics (and other atomic methods) to model the failure load of the SWCNT, continuum mechanics methods are considered in this paper. Based on some experimental and theoretical results, an elasto-plastic...
متن کاملStruggles of Social Forces on the Verge of Constitutionalist Revolution in Iran
On the verge of the Constitutionalist Revolution in Iran, the three social forces existing in the socio-political arena were competing with each other and at the same time, struggling with the Monarchy to increase their share of power: independent intellectuals, traditional followers of religion, and merchants. This rivalry set the scene for a discursive battle in which, each social force was t...
