Gasque described the physics behind the picket fence in a paper published last month in the journal Geophysical Research Letters. She calculated that in a region of the upper atmosphere farther south than that in which auroras form, electric fields parallel to Earth’s magnetic (磁的) field cou...
The Northern lights are poetry, and they are nature’s light show. They are elementary particle physics, superstition, mythology and fairy tales. 参考答案:北极光充满了诗情画意,使自然之光的展演。它们既蕴含着基本例子物理学的知识,又充满了迷信色彩,关于它还有许多神话传说。
Instead, the team behind the current research realized that the solar wind's magnetic field doesn't always line up precisely with Earth's. When it's skewed, it introduces asymmetry between the North and South Poles into Earth's magnetic field — and that, in turn, causes the mismatch betwe...
To more directly test this connection, Dr. Jim Schroeder, an Assistant Professor of Physics at Wheaton College in Illinois, led a team of scientists in performing laboratory experiments. Using the Large Plasma Device (LAPD) at UCLA's Basic ...
