Upgrading it to give the exact latitude and longitude of the collision wasn’t simple work, since Chesley had to factor in the spin, orientation and rotational wobble of the Earth at each moment.

要知道软件升级到可以预测撞击的确切经纬度绝非易事，因为切斯利每次都要将地球自传，方向及旋转轴等因素考虑在内。

We'll also discuss the conversion into actual geometry and how to better control the orientation of the mesh using Spin and Align.

我们 ' 还将讨论转化为实际的几何和如何更好地控制方向的网格使用自旋和对齐。

We're not going to front like we understand exactly how it works, but two IBM researchers in California have announced that they've gotten closer to controlling the orientation and magnetic spin of individual iron atoms on a copper surface, which would have huge implications for nanotech storage -- imagine the basic tech in your hard drive shrunk down the molecular level.

ENGADGET: IBM researchers get closer to nanotech hard drives

Andrew Kent, a physicist at New York University, spends most days running electricity through a magnet smaller in diameter than a single cell, trying to determine the lowest current at which an electron's spin changes orientation.
