Power Law Department of Physics at Harvey Mudd College

5 hours ago Power Law. When one quantity (say y) depends on another (say x) raised to some power, we say that y is described by a power law. For example, the distance traveled by an object in free fall (in the absence of air resistance) is given by. s ( t) = 1/2 gt2 (1) Ignoring the dependence on g, this equation says that s is proportional to the square of t.

The Power Law: What It Means for Your Startup Shortform

3 hours ago

1. Venture capitalists search out promising tech startups to invest in for a share of the profits. While many of them don’t fully understand it, the power law greatly influences their results. If companies in a venture fund portfolio gain value and go public or are sold to larger companies, the venture fund makes money. However, a venture fund typically loses money at first because most of the companies in its portfolio fail soon after starting. The investors hope the fund’s value will shoot up in a few years when the most successful startups experience exponential growth and scale up. They try to identify companies that will excel, while hedging their bets—which is a mistake. They expect portfolio returns to be normally distributed, with good companies returning two to four times value, average ones remaining flat and some failing. So they aim for a diverse portfolio, which usually fails. This approach fails because, in reality, venture returns follow a power law: A very small number...
