Exchange of Words with Friends

[Arjen Dijksman's retweet of my words] Femto-Essays: "About a quote from Marie Curie." Femto-Essays (December 3, 2010). —I wonder how many US Nobel were originally not US citizen.

[To Arjen Dijksman] Thanks for your retweet of my blog post. But I'm afraid that your comment is against the spirit of the Marie Curie quote.

[From Arjen Dijksman] No offense:-) The comment was intended to show that it was not appropriate to count number of US Nobel, US community being international.

[To Arjen Dijksman] Thanks for your reply, which was the same as my interpretation of your comment after rethinking. [My response was a superficial one to your words, "US Nobel." (December 5)]
