Recent determinations of the Newtonian constant of gravity have produced values that differ by nearly 40 times their individual error estimates (more than 0.5%). In an attempt to help resolve this situation, an experiment that uses the gravity field of a one-half metric ton source mass to perturb the trajectory of a free-falling mass and laser interferometry to track the falling object was perf...

We investigate the coefficients generated by expressing the falling factorial (xy) as a linear combination of falling factorial products xy for l, m = 1, . . . , k. Algebraic and combinatoric properties are discussed, some in relation to Stirling numbers.

The visual system is tasked with extracting stimulus content (e.g. the identity of an object) from the spatiotemporal light pattern falling on the retina. However, visual information can be ambiguous with regard to content (e.g. an object when viewed from far away), requiring the system to also consider contextual information. Additionally, visual information originating from the same content c...

Baurès et al. [Baurès, R., Benguigui, N., Amorim, M.-A., & Siegler, I. A. (2007). Intercepting free falling objects: Better use Occam's razor than internalize Newton's law. Vision Research, 47, 2982-2991] rejected the hypothesis that free-falling objects are intercepted using a predictive model of gravity. They argued instead for "a continuous guide for action timing" based on visual informatio...

Even when we cannot directly see the light falling on an ensemble of objects, we tend to perceive object colors independently of the spectrum of this light. This color constancy may arise from comparisons of matte-reflected lights, but it may be facilitated by object highlights. We hope to develop a scheme whereby the human visual system might abstract illuminant-invariant object colors, subjec...

Of the many cues that could be used to gauge selfmotion, auditory cues seem to be the least studied. Listeners could potentially use either a sweep of rising sound intensity to judge their self-motion towards an object or conversely use a sweep of falling sound intensity to judge their motion away from an object. Whether the sweep is rising or falling the listener must judge both the change in ...

Temporal and spatial characteristics of fixations are affected by image properties, including high-level scene characteristics, such as object-background composition, and low-level physical characteristics, such as image clarity. The influence of these factors is modulated by the emotional content of an image. Here, we aimed to establish whether brain correlates of fixations reflect these modul...

The location of visual objects in the world around us is reconstructed in a complex way from the image falling on the retina. Recent studies have begun to reveal the different ways in which the brain dynamically re-maps retinal information across eye movements to compute object locations for perception and directing actions.

Human desires toward the heavens had been continued after Tower of Babel. Many high-rise buildings were constructed with technological progress in the 20 century. The tallest skyscraper of the world is Burj Khalifa (Dubai, UAE) with a height of 828 meters. Kingdom tower (Jeddah, KSA) would be tallest building with 1,000 meters about 2019 (1). Skyscrapers have lots of problems in terms of disast...
