Culture crash

Article Abstract:

The idea that physics might have something useful to contribute to economics arises because both fields are concerned with systems of many interacting components that obey specific rules. Statistical physics describes the behaviour of bulk matter based on the forces acting between atoms and molecules and economics studies the interactions between economic agents, market traders, or businesses.

Antigravity craft slips past patent officers

Article Abstract:

The grant of a patent by the US patent office to an antigravity device is reported for breaking its own resolution to reject inventions defying the laws of physics. However, it is not always easy to tell what the implications of a patent are and result in difficulties for the examiners allowing the patent.
