The North Star Gay Rodeo Association (NSGRA) is a gay rodeo association in the Midwestern United States (principally Minnesota and Wisconsin) founded to "spread the culture of rodeo", and raise funds for local charitable organizations. It seeks to provide access to the community of gay rodeo organizations in the United States to people of "all gender and sexual identities".[1] It is a nonprofit organization and member of the International Gay Rodeo Association (IGRA).

Body doubling or parallel working[1] is a strategy used to initiate and complete tasks, such as household chores or writing and other computer tasks.[2] It involves the physical presence, virtual presence through a phone call, videotelephony or social media presence,[2][3] of someone with whom one shares their goals, which makes it more likely to achieve them.[1] For some people, it works best to both do similar tasks, while for others, just being in the same (virtual) room is enough.[2]

Anthemius, better known by the modern Russian spelling of his name, Onfim, was a boy who lived in Novgorod in the 13th century, some time around 1220 or 1260. He left his notes and homework exercises scratched in soft birch bark which was preserved in the clay soil of Novgorod.

The blue field entoptic phenomenon is an entoptic phenomenon characterized by the appearance of tiny bright dots moving quickly along undulating pathways in the visual field, especially when looking into bright blue light such as the sky. The dots are short-lived, visible for about one second or less, and traveling short distances along seemingly random, undulating paths. Some of them seem to follow the same path as other dots before them. The dots may appear elongated along the path, like tiny worms. The dots' rate of travel appears to vary in synchrony with the heartbeat: they briefly accelerate at each beat. The dots appear in the central field of view, within 15 degrees from the fixation point. The left and right eye see different, seemingly random, dot patterns; a person viewing through both eyes sees a combination of both left and right visual field disturbances. While seeing the phenomenon, lightly pressing inward on the sides of the eyeballs at the lateral canthus causes the movement to stop being fluid and the dots to move only when the heart beats.

In astronomy, a trojan is a small celestial body (mostly asteroids) that shares the orbit of a larger body, remaining in a stable orbit approximately 60° ahead of or behind the main body near one of its Lagrangian points L4 and L5. Trojans can share the orbits of planets or of large moons.

The Interplanetary Transport Network (ITN) is a collection of gravitationally determined pathways through the Solar System that require very little energy for an object to follow. The ITN makes particular use of Lagrange points as locations where trajectories through space can be redirected using little or no energy. These points have the peculiar property of allowing objects to orbit around them, despite lacking an object to orbit. While it would use little energy, transport along the network would take a long time.

Autorotation is a state of flight in which the main rotor system of a helicopter or other rotary-wing aircraft turns by the action of air moving up through the rotor, as with an autogyro, rather than engine power driving the rotor. The term autorotation dates to a period of early helicopter development between 1915 and 1920, and refers to the rotors turning without the engine. It is analogous to the gliding flight of a fixed-wing aircraft. Some trees have seeds that have evolved wing-like structures that enable the seed to spin to the ground in autorotation, which helps the seeds to disseminate over a wider area.

Bombardier beetles are ground beetles (Carabidae) in the tribes Brachinini, Paussini, Ozaenini, or Metriini—more than 500 species altogether—which are most notable for the defense mechanism that gives them their name: when disturbed, they eject a hot noxious chemical spray from the tip of the abdomen with a popping sound.

Daniel Clement Dennett III was an American philosopher, writer, and cognitive scientist whose research centers on the philosophy of mind, philosophy of science, and philosophy of biology, particularly as those fields relate to evolutionary biology and cognitive science.
