networking and math


DesiMartini.com, an SMS-based online social networking site for Indians around the world, launched by Pahwa KBS last month, says it has plans to beat the competition and reach a registered user base of 1 million members in six months.Started by 25-year-old Vivek Pahwa, a recent graduate from the Indian School of Business, and the University of Michigan, Ann Arbor, the site lets users create their own customisable homepages, send in updates (what they are doing) via SMS wherever they are, upload and share pictures, join groups and communities, chat with other members, and stay in touch with old friends and discover new ones.
Social networking has been one of the hottest areas of interest since Web 2.0 took off as a concept and media buzzword. In one of the most high profile media deals of 2005, Rupert Murdoch’s News Corporation bought MySpace for $580 million, a staggering amount at the time. This year, viral video has become the latest hot category with the defining Internet deal of 2006 being the sale of YouTube to Google for $1.76 billion.
math theorem...1.A (presumably autobiographical) character in one of astrophysicist Fred Hoyle's novels opined the following. "I figure that if to be totally known and totally loved is worth 100, and to be totally unknown and totally unloved is worth 0, then to be totally known and totally unloved must be worth at least 50."
2..Dunbar's number is a value significant in sociology and anthropology. Proposed by British anthropologist Robin Dunbar, it measures the "cognitive limit to the number of individuals with whom any one person can maintain stable relationships". The so-called rule of 150, states that the size of a genuine social network is limited to about 150 members ( called Dunbar's number). Dunbar supports this hypothesis through studies by a number of field anthropologists. These studies measure the group size of a variety of different primates; Dunbar then correlate those group sizes to the brain sizes of the primates to produce a mathematical formula for how the two correspond
