[Zz] The beauty of mathematics and the waves

Reposted from Dr Wu: http://jun.wu.googlepages.com/
Two famous series of articles: "The beauty of mathematics" and "the top of the waves ". People who do not know about computers can also learn a lot from it.

Over the past one hundred years, some companies have been lucky, conscious, or unconsciously standing on the cusp of the technological revolution. Once at that point, even if you don't do anything, you can move forward with the waves for a decade or longer. Over the past decade, they have represented the wave of technology until the next wave.

From one hundred years ago, at&t, IBM, apple, Intel)
Microsoft, Cisco, Yahoo, and Google)
Companies have been pushed to the waves. Although they come from different fields, some of them have declined or are fading, but they are all brilliant. They were once global empire and ruled themselves.
Industry.

People in these companies, big and small, seem lucky to outsiders. Because, for a company, catching up with a wave cannot guarantee that it will survive forever;
Yes, it is enough for a person to catch up with such a wave in his life. For a young man, the best thing is to catch up with the tide. It is difficult to predict the future, but look at the past and the present,
We may be able to understand some truth. I would like to share with you what I have seen and heard over the years in the space of Google blackboard. I will talk about my views on each wave and my views on each of the above companies.
And understanding of the key figures. In today's highly commercialized world, technological advances and business opportunities are inseparable. Therefore, I also want to mention venture capital companies that indirectly influence the technology wave, such
Kpcb, Sequoia Venture Capital (Sequoia), and investment banks that have supported technology for centuries, such as Goldman Sachs.
