这种学术加速度给人造成了一种印象，即任何超过几年时间长的科研成果都已经过时。

Because of the accelerated pace, the impression spreads that anything more than a few years old is obsolete.

但是，绝大部分的程序都需要经过允许才可以使用地点数据和照相机，使用加速度感应器却没这个要求。

But whereas most apps have to ask permission to access location data or the camera, that's not so for the accelerometer.

经过一些时间的自由降落后，落体运动得很快，以至空气拽力(阻力)与落体的重量相等，于是就没有加速度了。

After some time of uninterrupted fall, the body is moving so rapidly that the drag of the air is as great as the weight of the body, so that there is no acceleration.

But I can add to this some number, like 96, that'll still have the property that if you take two derivatives, you're going to get the same acceleration.

但是我可以在后面加上某个数,比如96,经过两次求导你仍会得到,同样的加速度
