Well, in relativity they're all really the same thing, or at least interconvertible. But there are more glaring examples of this. What do you get when you multiply a number of newtons by a number of metres? It could be either joules of energy or newton-metres of torque, depending on what you're doing. You definitely don't want to add those together! I'm not sure how you teach a unit system to deal with things like that. Somehow when you do the multiplication you have to specify whether you're calculating energy or torque. -- Greg _______________________________________________ Python-ideas mailing list -- python-ideas@python.org To unsubscribe send an email to python-ideas-le...@python.org https://mail.python.org/mailman3/lists/python-ideas.python.org/ Message archived at https://mail.python.org/archives/list/python-ideas@python.org/message/HJ3ODB625ZOWVY2NIDOQ2ZEGUA36Z3BI/ Code of Conduct: http://python.org/psf/codeofconduct/
