    en.wikipedia.org/wiki/Dassault_Falcon_7X

    Dassault launched the FNX at the 2001 Paris Air Show, aiming for a 10,500km (5,700nm) range at Mach 0.88, up from the Falcon 900EX's 8,300 km at Mach 0.84. Its new high-speed wing is 1.86 m (6 ft 1 in) longer with 5° higher wing sweep than the 900 wing; while its fuselage is 20% longer, it keeps the same cabin cross-section but with a new curved windscreen.

    When the magnetization vector is perpendicular to the reflection surface and parallel to the plane of incidence, the effect is called the polar Kerr effect.To simplify the analysis, and because the other two configurations have vanishing Kerr rotation at normal incidence, near normal incidence is usually employed when doing experiments in the polar geometry.

    en.wikipedia.org/wiki/Polar_ice_cap

    A polar ice cap or polar cap is a high-latitude region of a planet, dwarf planet, or natural satellite that is covered in ice. [ 1 ] There are no requirements with respect to size or composition for a body of ice to be termed a polar ice cap, nor any geological requirement for it to be over land, but only that it must be a body of solid phase ...

    Total loss of the Greenland ice sheet would increase regional temperatures in the Arctic by between 0.5 °C (0.90 °F) and 3 °C (5.4 °F), while the regional temperature in Antarctica is likely to go up by 1 °C (1.8 °F) after the loss of the West Antarctic ice sheet and 2 °C (3.6 °F) after the loss of the East Antarctic ice sheet.

The polar regions, also called the frigid zones or polar zones, of Earth are Earth's polar ice caps, the regions of the planet that surround its geographical poles (the North and South Poles), lying within the polar circles.

    Van Allsburg based the story on a mental image of a child wandering into the woods on a foggy night and wondering where a train was headed. [4]At the premiere of the film, Van Allsburg stated that Pere Marquette 1225, a 2-8-4 Berkshire N-1 class steam locomotive, formerly owned by the Michigan State University and now owned by the Steam Railroading Institute in Owosso, was the inspiration for ...
