在看 android code 時，看到這樣的東西：

/** Standard gravity (g) on Earth. This value is equivalent to 1G */
public static final float STANDARD_GRAVITY = 9.80665f;
/** values returned by the accelerometer in various locations in the
universe.
* all values are in SI units (m/s^2) */
public static final float GRAVITY_SUN = 275.0f;
public static final float GRAVITY_MERCURY = 3.70f;
public static final float GRAVITY_VENUS = 8.87f;
public static final float GRAVITY_EARTH = 9.80665f;
public static final float GRAVITY_MOON = 1.6f;
public static final float GRAVITY_MARS = 3.71f;
public static final float GRAVITY_JUPITER = 23.12f;
public static final float GRAVITY_SATURN = 8.96f;
public static final float GRAVITY_URANUS = 8.69f;
public static final float GRAVITY_NEPTUNE = 11.0f;
public static final float GRAVITY_PLUTO = 0.6f;
public static final float GRAVITY_DEATH_STAR_I = 0.000000353036145f;
public static final float GRAVITY_THE_ISLAND = 4.815162342f;

重力的資訊竟然整個太陽系的都準備好了，另外還惡搞了兩個其他的
THE_ISLAND 有人說是影集 LOST 裡面的，我也不知道
至於 DEATH_STAR 也不知道是那來的，可能是 STAR WARS 裡面的

不過前面九大行星的重力資料，對照幾個應該是正確的
實在是太有趣了，android 手機可以上太空了
