②My children like baths, not showers, so how can I tell them that they must keep clean and then insist, “You must必须not use the bath?" They won't stay clean. ③I don't mind a cool house, but it has to be kept
As with South America, which can be seen on every globe hanging from the Panama Canal like an inverted, slightly off-centred pear, North America is obviously the great land mass below the North Pole and between the Pacific and Atlantic oceans. But, even if North America can be located ...
While Earth's North Pole is currently aimed at the star system Polaris, it'll line up with Gamma Cephei two millennia from now. Adjust your stargazing plans accordingly. Just as Earth isn't the only oblate spheriod in town, there's nothing special about its axial tilt. Other planets have...
The International Crisis Group, in a report entitled “The Covid-19 Pandemic and Deadly Conflict” (ICG, 2020), recognized that “the long- and short-term consequences for deadly conflict are less well understood”. Severalregional studieshave aimed to explore the possible implications of the CO...
Allison 1 In the lead-up to the Cretaceous/Paleogene mass extinction, dinosaur diversity is argued to have been either in long-term decline, or thriving until their sudden demise. The latest Cretaceous (Campanian–Maastrichtian [83–66 Ma]) of North America provides the best record to address ...
In other words, someone standing at the North Pole on Earth would experience time the same way as someone standing on Mars. Newton's view on time kept it separate from space. When Albert Einstein introduced his Theory of Relativity in the early 20th century, however, he suggested that time...
Besides, for potentials having the pole of the order 3 or higher at r = 0 or for relatively large r, it would be preferable to have L(L + 1) without the substitution by (L+1/2)2. This is yet another restriction of the QA validity in this procedure. In the first part of the ...
Instead, the planet is far wider at the equator and flattens the closer you are to each pole — or has a single shorter axis. In other words, Earth is a close approximation of an oblate spheroid ellipsoid. While it’s not perfect, the earth ellipsoid has many uses, including plotting ...
Numerous studies have examined the effects of the provision of supplementary food on aspects of avian reproductive success, but far fewer have gone on to examine the potential positive effects of food supplementation on the demographic rates which are key for population growth rate. Testing for poten...
