  It’s finish.
  Linear Algebra, MIT OpenCourseWare 18.06, prof. G. Strang
  For me, a whole term’s learning is full of exciting, funny and moving.

  When I saw the graph of Ax=b, simple linear equations became vision of vector spaces.
  When I saw the network f=ATCAe, a whole new world of NET came to my mind.
  When I saw the least squares that a powerful line thought dots. I knew I wouldn’t guess anymore.
  When I saw the number of rabbit solved by eigenvalues, I saw the answer I wait for three years.
  When I saw the eA & vibration of springs y=cosx, I couldn’t believe It comes true.
  When I saw the ellipse grow in R3, I knew that’s the most fantastic thing I have ever seen. 
  When I saw the JPEG2000 with wavelets, I was so surprised that I can’t close my mouth.

  When I saw your “thanks for taking this course", I just want to cry.

  When I first viewed video lecture, I feel nervous and the course is full of my exception,
  When I had viewed the last video, I feel confident and the course is full of my appreciation.

　　就这样结束了。
　　线性代数。麻省理工学院18.06，G. Strang教授。

　　可能比较特别，对我来说，线性代数是Linear Algebra的意思，而Linear Algebra就是MIT 18.06.
真是有对比才知高低，我们大学用着连一张图片都找不出的迂腐陈旧的讲义，我们的高等代数也常常让我震惊，震惊还有这么过时的教材，这么猥琐的证明，这么抽象的概念。
　　这更让我庆幸，我庆幸我生活在这样一个充满着技术革命的时代，MIT智能传播，天下为公的思想深深播种在我心，我相信会有一天开出美丽的花朵。

　　大一的生活离不开Linear Algebra的学习，我第一次忐忑不安的打开video，十年英语的学习终于获得了回报，Ax=b的图像我一辈子都忘不了。在机房，在电子阅览室，在姥姥家，在宿舍，在教室……多少次我一边看着屏幕，一边拿笔计算；多少次我睡在床上思索着课程的内容；多少次我看着屏幕惊得目瞪口呆。线性代数给与我希望，并一直激励我前进。

　　当我第一次看讲座，我略感紧张并对课程充满期待。
　　当我看完最后一讲，我满怀信心并对课程充满感激。
