Dramatic Challenge to Barnes & Nobles Business Model

This one of the most vivid examples of challenges to the existing business model of a firm. The Wall Street Journal reports:

After nearly 17 years of consistent growth, Barnes & Noble is stumbling. Revenue fell 3% to $5.12 billion for the fiscal year ended Jan. 31, 2009, while earnings dropped about 45% to $76 million.

When it launched the iPad last month, Apple championed a new approach to e-book pricing. Earlier this year, most large publishers agreed to establish a so-called agency model, where the publisher receives 70% of the digital price while e-book sellers act as agents and receive 30%. While some best sellers remain at $9.99, many major authors are priced at $12.99 or $14.99.

The Power of Infinity

Steven Strogatz explains beautifully how the concept of inifinity first tripped up philosophers but then provided them with a powerful tool to calculate things that could not be calculated without taking things to inifity. I wish I had had as good a math teacher as Strogatz. The lesson here is also that Strogatz does not provide a solution to Zeno’s paradox but that he shows that even without fully removing the puzzles around infinity one can use the concept to get more knowledge in other areas.
