If you are really that interested this ieeexplore.ieee.org/xpl/abstractKeywords.jsp?arnumber=4998775 will have the errors but it is behind a paywall so you have to go to a library. | |
| Jan 24, 2014 at 6:29 | comment | added | Pacerier | @anna, I mean did we actually observed 0.0000000... up to like 200 decimal places? Because if we did, we can say it's practically zero. Or did we actually observed data for only ~10 decimal places? | |
| Jan 23, 2014 at 5:10 | comment | added | anna v | @Pacerier I mean we can be always approaching the limit but not reaching it within our lifetimes or experimental errors. If we cannot measure 0 it is never 0 for physics. | |
| Jan 22, 2014 at 21:40 | comment | added | Pacerier | @anna, When you say "epsilon delta relationship", do you mean "yes, exactly 0.000000000 resistance is possible" or do you mean "no, we can never get exactly 0.000000000 resistance"? | |
