Hi,
I have two very specific questions.
I was trying to read this paper :
http://downloads.bbc..._connection.pdf
and i noticed that equation 3 and equation A6 were different :
Eq3 : L(t)=Q(t)/£(t) (not dimensionally correct)
and
Eq A6 : L(t)=Q(t)/£(t) * delta_t
When you read under equation 3, you understand why this is like that ; they say :
"As seen in Eq.(A6) of Appendix A, lifetime indeed has the dimension of time, being multiplied by the sampling time interval (which is here equal to unity–1 day)."
Questions :
1/ Is it ok to have a dimensionally wrong equation if you say why in the text right next to it (i.e. numbers have a dimension and here because the time interval chosen is unity ) ?
2/ Is it common practice in Physics to do that ?
Thank you !
Note : i do not want a comment on the paper itself, just on this specific point.
