Except that in this case, the molecular details of life are useful. If you want to know why people need salt you need to know about ion channels. (This is in contrast to your Eiffel Tower example, where you don't gain much insight by looking at molecules than you knew at the material-science level.)
- Turing_Machine 9y agoBut ion channels (and their function) are on a much higher level than quarks. Looking at things at the quark level doesn't tell you anything about ions, or salt, or, for that matter, people. :-)
