"A Swedish physicist can not discuss his work with fifty people unless he goes abroad. A Swedish economist can get opinions and instructions in his native language from thousands upon thousands of his fellow citizens"

This quote by George Stigler is highlighting the distinctions in between the fields of physics and economics. Stigler is recommending that the field of physics is more isolated than economics, as a Swedish physicist would need to go abroad to discuss their work with fifty people, whereas a Swedish financial expert can get opinions and guidelines in their native language from countless their fellow residents. This implies that the field of economics is more available and has a bigger community than physics. Stigler is most likely making this contrast to emphasize the significance of economics in society, as it is more commonly talked about and comprehended than physics. This quote likewise recommends that the field of physics is more intricate and specific than economics, as it needs more effort to discover individuals to discuss it with.
