Linear?

June 5, 2007 at 5:18 pm | | crazy figure contest, literature

It’s not the worst figure, but I did laugh a little that only 2 out of 10 points fit comfortably within their respective error bars.

  1. they do say:

    For ionic liquids with viscosity values higher than 100 cP … a substantial deviation from the linearity could be observed.

    the data stops at 85 cP. i guess substantial must = HUGE. but it sounds like this nonlinearity isn’t unexpected.

  2. But the trend I see in the figure looks less like nonlinearity and more like the fact that trying to apply some scaling law to the different systems is in error. This seems especially true since you can do a pretty good job drawing different straight lines through each of the Coumarin and the PRODAN points.

  3. yeah, why didn’t they draw three different fits and attribute the different slopes to differences among the dyes?
    .
    or, even better, don’t include a linear fit.
