The coming disintermediation - The Dismal Science

Eric Crampton Dec 09, 2013

The great Eli Dourado shows the way:What’s even more exciting is the next generation of disintermediating technologies. Bitcoin could displace some financial institutions—to varying degrees, banks, the Federal Reserve, Western Union, and credit card companies.Mesh networks could solve the last-mile problem of Internet service delivery, which tends to be monopolized or at least concentrated. 3D printers could disintermediate supply … Read More

Foiling Fiddled Data - Molecular Matters

Synthetic chemists produce new compounds by reacting various starting materials and/or reagents together. In order to determine the structure of what she has made, the chemist must run a series of analyses, which not only prove the compound has the structure she claims to have made, but also that it is present in pure form. These analyses include mass spectrometry, … Read More
