But more surprising miracle is,however, not the majestic pyramids of Khufu posture, but the number of "coincidences": people now know,the distance from the Earth to the sunis 146.24 million km, and the average distance between the Sun is 146590000 km, being a unit of astronomical measurement; If the current height of the pyramid of Khufu 146.59 meters get multiplied by the billions, the result is exactly 146,590,000 kilometers!

但更为令人吃惊的奇迹，并不是胡夫金字塔的庞大，而是发生在胡夫金字塔上的数字&巧合&：人们到现在已经知道，从地球到太阳的距离，也就在14624万公里到15136万公里之间，而人们将地球与太阳之间的平均距离14659万公里作为一个天文度量单位；如果把胡夫金字塔的高度146.59米乘以十亿，其结果正好是14659万。

The particles with higher energies can penetrate into the magnetosphere with larger distribution of the pitch angle, but only those with directions along the magnetic field lines can reach the ground.

能量越高的粒子进入到地球磁层上空的角度范围越大，但仍然只有沿着磁力线入射的粒子才能到达地球表面。

To travel aroundthat circumference in 24 hours, a point on Earth's surface has to move at 1,038 mph(1,669 kph). A launch from Cape Canaveral, Florida, doesn't get as big a boost from

在地球表面的某一点上以每小时1038英里(约合每小时1669公里)的速度转动，才能在24小时内走完地球的一周。

The measurements made by Van Allen's experiment led to an unexpected and startling discovery -- an earth-encircling belt of high energy electrons and ions trapped in the magnetosphere now known as the Van Allen Radiation Belt.

Van Allen的实验测得的结果找到了意想不到、令人吃惊的发现—在地球磁气圈外截流了一条环绕地球的高能电子和离子环，现在被称为 Van Allen辐射带。

Then earth invites each to go pay a visit to each region that on e believes is in the light earth dream that is nearby one's region of origin.

而地球邀请每个人去拜访一下在你居住地附近你认为是在光明地球梦想中的每一个区域。

For Earth's eastern hemisphere, centering on India, there will be a very small partial lunar eclipse, with the moon just skimming Earth's shadow.

对于地球东半球的人们来说，以印度为中心，正好会有一次小小的月偏食，那时月亮刚好进入地球的阴影部分。

Our sun is so small and our earth, its offspring, is so tiny that when I think of the magnitude, I think of what O. Henry described as a "Statue of What's the Use."

太阳在宇宙中是那么微小，太阳的孩子地球则更是微不足道，以至于我一想到地球的分量，就想起欧·亨利说过的那句话——&无用的化身&。

Inspired to make his own contribution, astronomer Ralf Vandebergh set out to record images of some historic spacecraft in Earth orbit -- captured with his own modest equipment and a hand-guided, 10-inch, Newtonian reflecting telescope.

说明：今年，美国航天局祝贺其成立50周年，天文学家 Ralf Vandebergh 决定作出一些自己的贡献，用他10英寸的牛顿反射式望远镜在地球上拍摄记录下航天器在地球轨道上的历史性的瞬间。

This group is an outgrowth of the International Geophysical Year I.G.Y.

这个组织是国际地球物理学年会的一个派生机构，但是它的项目已经从地球物理学拓展到地图测绘和生物学。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
