Mean anomaly, a measure of time in the study of orbital dynamics Pioneer anomaly , the observed deviation of the trajectories of some uncrewed space probes, and especially Pioneer 10 and Pioneer 11 South Atlantic Anomaly , an area where the Earth's inner Van Allen radiation belt comes closest to the Earth's surface
The evidence for this statement has been accumulating for more than a century. Studies of benign hallucinatory experiences go back to 1886 and the early work of the Society for Psychical Research, [2] [3] which suggested approximately 10% of the population had experienced at least one hallucinatory episode in the course of their life.

The true anomaly is usually denoted by the Greek letters ν or θ, or the Latin letter f, and is usually restricted to the range 0–360° (0–2π rad). The true anomaly f is one of three angular parameters (anomalies) that defines a position along an orbit, the other two being the eccentric anomaly and the mean anomaly.
The Association for the Scientific Study of Anomalous Phenomena (ASSAP) is a United Kingdom-based learned society, education and research charity, [4] dedicated to scientifically investigate alleged paranormal and anomalous phenomena, with a view to approaching the subject in its entirety rather than looking into the psychology of individual phenomenon. [5]
Gravity anomaly, difference between the observed gravity and a value predicted from a model Bouguer anomaly, anomaly in gravimetry; Free-air anomaly, gravity anomaly that has been computed for latitude and corrected for elevation of the station; Iridium anomaly, an unusual abundance of what is normally a very rare element in the Earth's crust
Shown are mean anomaly and true anomaly for two units of time. (Note that for visual simplicity, a non-overlapping circular orbit is diagrammed, thus this circular orbit with same orbital period is not shown in true scale with this elliptical orbit: for scale to be true for the two orbits of equal period, these orbits must intersect.)
A bootstrap paradox, also known as an information loop, an information paradox, [6] an ontological paradox, [7] or a "predestination paradox" is a paradox of time travel that occurs when any event, such as an action, information, an object, or a person, ultimately causes itself, as a consequence of either retrocausality or time travel.
By definition, the paranormal (or supernatural) does not conform to conventional expectations of nature. Therefore, a phenomenon cannot be confirmed as paranormal using the scientific method because, if it could be, it would no longer fit the definition. [20] (However, confirmation would result in the phenomenon being reclassified as part of ...
