I may be thinking too much into this, but couldn't she also not want the website to know her mass? Momentum is Mass*Velocity, and Velocity can be derived from change in position [[Special:Contributions/173.245.56.159|173.245.56.159]] 05:34, 14 January 2015 (UTC) | I may be thinking too much into this, but couldn't she also not want the website to know her mass?

:That was my understanding, too. Moreover, I don't see any humor in applying the uncertainity principle to macroscopic objects.

Plus, to the "I don't see any humor in applying the uncertainity principle to macroscopic objects." person, above, please pass by your local XKCD offices at the first opportunity in order to hand back your XKCD Membership Card. You're obviously not one of us! ;) [[Special:Contributions/141.101.98.191|141.101.98.191]] 16:28, 14 January 2015 (UTC) | Plus, to the "I don't see any humor in applying the uncertainity principle to macroscopic objects." person, above, please pass by your local XKCD offices at the first opportunity in order to hand back your XKCD Membership Card.

Per the explanation: "Randall suggests the poor accuracy of the compasses in mobile phones (measuring the angular position) is due to the gyroscopes being too good. (If both the gyroscope and the compasses were completely accurate, it would violate the uncertainty principle)." | Per the explanation: "Randall suggests the poor accuracy of the compasses in mobile phones (measuring the angular position) is due to the gyroscopes being too good.

The compass points in a particular direction but tells you nothing about location or momentum. How would it be involved in any violation of Uncertainty? The gyroscope and GPS I could see, maybe. But the compass? I don't see how it combined with anything could involve Uncertainty. - Equinox [[Special:Contributions/199.27.128.117|199.27.128.117]] 16:46, 14 January 2015 (UTC) | The compass points in a particular direction but tells you nothing about location or momentum.

+1 for this being about the uncertainty principle. Frankly, I'm surprised there's any controversy (many of the alternative explanations offered seem very unlikely, quite apart from anything else): if there's any ambiguity in the cartoon itself, surely the title text (by riffing on another pair of conjugate variables) clears that up? | +1 for this being about the uncertainty principle.
