The current state of creation astronomy is reviewed. Creationists have usually followed three basic approaches in the field of astronomy: 1) criticism of the big bang, 2) the argument of design, and 3) arguments for a recent creation. Many arguments that recent creationists use are found to be rather dated. Many of these arguments are still valid, but must be continually updated to reflect new ...

Perhaps the most extraordinary surviving relic from the ancient Greek world is a device containing over thirty gear wheels dating from the late 2nd century B.C., and now known as the Antikythera Mechanism. This device is an order of magnitude more complicated than any surviving mechanism from the following millennium, and there is no known precursor. It is clear from its structure and inscripti...

However, the use of the term parahemorheology has been criticized, because the prefix para implies that the rheology of fluids and structures in the perivascular spaces is secondary and less important than that of the vessel-blood organ. It is also imprecise, once it does not refer to the fluids and structures being considered. By contrast, the term perihemorheology implies the rheology of flui...

Abstract CASA, the Common Astronomy Software Applications, is primary data processing software for Atacama Large Millimeter/submillimeter Array (ALMA) and Karl G. Jansky Very (VLA), frequently used also other radio telescopes. The CASA can handle from single-dish, aperture-synthesis, Long Baseline Interferometery (VLBI) One of its core functionalities to support calibration imaging pipelines AL...

When we think of Greek vases we generally have in mind Greek pottery, which has survived in quantity. Clay, one of the most perishable of materials, becomes one of the most indestructible in the firing. In fact, much of our knowledge of ancient civilizations is derived from the potsherds that are found in successive layers on ancient sites; a pot, once fired, may break into a hundred pieces, bu...

1 Consequence Relations A useful notion that cuts across both semantic (model-oriented) and syntactic (derivation-oriented) issues is the notion of a consequence relation. We will use capital Greek letters like Γ,∆ (Gamma and Delta) to refer to finite sets of formulas, and lower case Greek letters like φ, ψ (phi and psi) to refer to individual formulas. We will save ink by writing Γ,∆ for the s...
