I have the same thing happened a while ago.
I bought a GC with Chase CC.
The store did not charge the activation fee which I was not aware of. Of
course the card could not be used.
I immediately called the store (only 30 minutes away), manager told me they
ran out of the GC, otherwise could reload to another card. Manager told me
there was nothing else he can do, I have to call GC company.
Called GC company several times, spent hours on the phone, faxed all receipt

这是一个precession的例子吧。如果全是理想条件会一直转下去,但不是理想状态,平
衡被打破,便会沿着重力场的方向慢慢倒下去 ,但会是一个sprial trajectory,
不是物理专业。
总而言之会是一个自转+转绕重力场G的方向的一个旋转的结合,

上面的资料很好。
另外一个有趣处,尚书有据说是尧时代的天文记录,星星位置是随时间缓慢变化的。由
现代天文学数值计算后的结果,还真就是那个时代的记录。所以有以下悖论:要么承认
尚书确实有部分内容是唐尧时代的记录结果,要么就是战国时期伪造,但是伪造者具有
现代天文知识和现代电脑时代的计算能力。
以下拷贝:
“我国古代经籍,间有载及星辰之位置者,苟其所记之星次为当时实在现状,则以岁差
之理,即能推定经书之年代。近顷梁任公先生谓《尚书·尧典》所记“仲春日中星鸟,
仲夏日永星火”等”
东晋天文学家虞喜,发现恒星的位置有偏移,进而发现岁差,并定出冬至点每50年后退
1°。《宋史·律历志》记载:“虞喜云:‘尧时冬至日短星昴,今二千七百余年,乃东
壁中,则知每岁渐差之所至。’”岁差这个名词即由此而来。
岁差(axial precession),在天文学中是指一个天体的自转轴指向因为重力作用导致在
空间中缓慢且连续的变化。地球自转轴的方向逐渐漂移,追踪它摇摆的顶部,以大约26

If you are not so emergent, you can wait up to for 4 months.
In the past several years, this kind of cases VSC should be precessed in 2-4
weeks, some cases only took 1 week.

Like what I said before, USCIS didn't make such a mistake. Jan and Feb cases
have been precessed for months and they are speeding up. The processing
time is mainly determined by background check.ONline status is not very
