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.

Logical Incrementalism in Product Development

This little exerpt from the NY Times explains well the concept of logical incrementalism in management.

Mr. Schmidt didn’t stop there.

But he said both companies would have “the next two to three years to figure it out.”

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.
