Occam's razor - Wikipedia Andreas Cellarius's illustration of the Copernican system, from the Harmonia Macrocosmica (1660). The motions of the sun, moon and other solar system planets can be calculated using a geocentric model (the earth is at the centre) or using a heliocentric model (the sun is at the centre). Both work, but the geocentric system requires many more assumptions than the heliocentric system, which has only seven. This was pointed out in a preface to Copernicus' first edition of De revolutionibus orbium coelestium. In science, Occam's razor is used as a heuristic technique (discovery tool) to guide scientists in the development of theoretical models, rather than as an arbiter between published models. In the scientific method, Occam's razor is not considered an irrefutable principle of logic or a scientific result; the preference for simplicity in the scientific method is based on the falsifiability criterion.

How Design Thinking Will Reshape Business Model Innovation The use of digital tools has revolutionised the architectural world. Computer Aided Design (CAD) software allows architects like Gehry to try out things that simply weren’t possible before through other design thinking processes. The business world has limited access to CAD software for strategy and innovation. That’s what we’re trying to do at Strategyzer: to allow teams to sketch out multiple models of their value propositions and business models, and to simulate “what could be”. To stress test assumptions and build a toolbox for quick experimentation that encourages cheap failure and learning. Add to that the ability to collaborate with team members globally, which allows companies to integrate a lot more feedback and knowledge throughout the business design process.

The Death Of Expertise I am (or at least think I am) an expert. Not on everything, but in a particular area of human knowledge, specifically social science and public policy. When I say something on those subjects, I expect that my opinion holds more weight than that of most other people. I never thought those were particularly controversial statements.
