An arc of a circle with the same length as the radius of that circle corresponds to an angle of 1 radian. A full circle corresponds to a full turn, or approximately 6.28 radians, which is expressed here using the Greek letter tau (τ). Some special angles in radians, stated in terms of 𝜏. A comparison of angles expressed in degrees and radians.
The decreasing bank angle together with the decreasing airspeed during the second half of the chandelle will maintain a constant turn rate. The turn needs to be kept coordinated by applying the correct amount of rudder throughout the maneuver. From a practical point of view, the chandelle may be used to turn an aircraft within a minimal turn ...
A half-turn may refer to: One half of a full turn, an angle measure equivalent to 180 degrees or π radians Considering only points in a plane, a half turn is equivalent to a point reflection; Pi (π), a mathematical constant representing a half-turn in radians; A U-turn: a driving maneuver used to reverse direction

The Battle of Marathon, an example of the double-envelopment, a form of flanking maneuver. In military tactics, a flanking maneuver is a movement of an armed force around an enemy force's side, or flank, to achieve an advantageous position over it. [1]
This glossary of entomology describes terms used in the formal study of insect species by entomologists.. When present, elytra of the Staphylinidae are markedly abbreviate. This fly in the genus Scaptomyza has clearly visible rows of para-sagittal acrostichal bristles on its thorax the alitrunk of aculeate Hymenoptera comprises the three thoracic segments, plus the propodeum, which strictly ...
A killing jar or killing bottle is a device used by entomologists to kill captured insects quickly and with minimum damage. [1] The jar typically contains gypsum plaster (plaster of paris) on the bottom to absorb a killing fluid. The killing fluid evaporates into the air and gasses the insect.
