... At an altitude of 200 kilometers (120 miles), a satellite zips by at 28,000 kilometers per hour, completing one orbit every 90 minutes. ... If the rocket engines force the satellite to go faster or slower than this velocity, the satellite goes into an elliptical orbit. A satellite in an elliptical orbit keeps changing its distance from Earth (see diagram ). ... At its farthest point from Earth (apogee), the satellite stops moving away from Earth and starts moving downward. ...

From the point of maximum eclipse along the Moon's shadow track across the Pacific Ocean, the Moon completely blocked the Sun for a total of 6 minutes and 39 seconds. But from the deck of this cruise ship the duration of the total eclipse phase was extended to a whopping 6 minutes and 42 seconds by the ship's motion along the shadow track. ... About APOD | ...

Underdetermined sets is a new type of data structures (terms) developed in Actor Prolog . ... The point is that an underdetermined set can include some indefinite rest (a tail) like a list in usual Prolog . At the same time, the order of elements of an underdetermined set can be arbitrary one and it does not affect results of unification of underdetermined sets. Moreover, Actor Prolog guarantees that a rest of an underdetermined set never contains elements that are explicitly given in the set. ...

SUMMARY OF THE RESEARCH PROPOSAL by Maxim Vsemirnov Research topic: Hurwitz and (2,3)-generated matrix groups and related problems. ... The reason to study these groups arises from the fact that the class of (2, 3)-generated groups together with three cyclic groups {1}, C2 and C3 is exactly the class of quotients of the classical modular group PSL2 (Z). ... The answer is known for sporadic groups, some exceptional groups of Lie type and for the most series of classical matrix groups of large rank. ...
