Figure 1-1 -- periodic table

The legend says halogens are to be colored yellow, but group VII are colored green, the same as the non-metals.

Note from the Author or Editor:
Yes. The figure itself needs to be recolored so that all the elements in column VII (not just Uus) appear the same pale yellow color as the color indicated in the key as Halogens.

In the image caption

The caption on page 5 reads "(used with permission)." This is a different format than the format used in chapter five (see page 70-76) which reads "Used with permission." Both should either use parens, or not, and should be capitalized, or not.

Note from the Author or Editor:
Please change the second line of the caption to Figure 1-12 to read "London Transport Museum collection. Used with permission.

5th paragraph

(Last sentence) Scaling a circle by increasing the radius linearly will result in quadratic increase of the area (proportional to r^2), not exponential increase (proportional to 2^r) or decrease.

Note from the Author or Editor:
Please replace the word "exponential" with "quadratic" in the last sentence on p31. Thanks!

Fig 4-4 and Fig 4-5

Figs 4-4 and 4-5 are crucial to the discussion about color luminosity, yet the data points are plotted as very light box outlines, with color barely visible. This seems to be a mistake, as the text explicitly says (p63, para 4) "I've also chosen to use filled circles as the plotting symbol in this version... This improves the perception of...color"

Note from the Author or Editor:
New figures have replaced the older ones.

last line

The code seems truncated.

Note from the Author or Editor:
Indeed, this code was truncated by one character: there should be a closing parenthesis [ ) ] immediately following ylab='density' on page 66.

Figure 5-10

The caption accurately references the three maps pictured. However, the references on pg 83 to that image reverse the references to sub-image (a) and (c). I believe this is because in all other uses in the chapter, the Vignelli map is (a) and the current (Tauranac-Hertz) map is (c). Because the image on pg 84 reverses the standard ordering of the three maps, I'd say the image (and matching caption) is the inconsistent, and therefore flawed, element, and not the references that would be accurate if the image was consistent. The image and caption on pg 84 should be corrected, and the reference on pg 83 should be left as-is.

Note from the Author or Editor:
Please switch the A and C images in Figure 5-10. The image 5-10A should become 5-10C, and the image 5-10C should become 5-10A.

First paragraph

The reference to "woman #4" looks like it should be a reference to "woman #3," based on the phrase "one strong tie within the group. Woman #3 is the only strong tie present.

Note from the Author or Editor:
On the third line of page 110, please change "to woman #4," to "to woman #3," so that it matches the image in Figure 7-7.

Image

The image shows four stages of the graph as the layout algorithm arranges the nodes. However, the first stage isn't topographically equivalent to the other three. It looks like the upper end of the leftmost link should connect to one node further right.

Note from the Author or Editor:
Please alter Figure 8-3 so that the shape on the far left (out of four) shows a shape topographically equivalent to the other three shapes. Please accomplish this by leaving all the circles (nodes) where they are, but moving the left-most line (edge) so that it connects not to the far-left node but to the node in the "center". This should yield a triangle shape on the bottom with a node sticking out alone to the left.

Figure 8-12

In the first half of the image, the red circle is labeled A. In the second half it's labeled R. Both should be R.

Note from the Author or Editor:
In the "Initial image" of Figure 8-12, there are two circles labeled A and D. The circle labeled A should instead be labeled R. (So that it matches the circle labeled R in the "Rotated image" part of Figure 8-12.)

Chatper 15 - 2nd paragraph

The second "YOUR-API-KEY-GOES-HERE" should be removed: TimesArticleSearch mySearch = new TimesArticleSearch("YOUR-API-KEY-GOES-HERE") ;

Note from the Author or Editor:
TimesArticleSearch mySearch = new TimesArticleSearch("YOUR-API-KEY-GOES-HERE") ; should be TimesArticleSearch mySearch = new TimesArticleSearch() ;

2nd paragraph

After looking at this page http://blog.blprnt.com/blog/blprnt/multi-faceted-searching-with-the-nytimes-apis, I think each instance of "r.articles" should be replaced with "r.results": println("FIRST HEADLINE: " + r.articles[0].title) ; println("100th ARTICLE URL: " + r.articles[9].url) ; println("AUTHOR #" + i + ": " + r.articles[i].author) ; There seem to be a lot of errors in this chapter, but I've just listed a few.

Note from the Author or Editor:
println("100th ARTICLE URL: " + r.articles[9].url) ; should be println("10th ARTICLE URL: " + r.articles[9].url) ; As to whether r.articles should be changed to r.results, I'm as yet unsure.

2nd paragraph

To match the line above, it should say "10th ARTICLE URL": Or, to get the web URL for the 10th article: println("100th ARTICLE URL: " + r. articles[ 9] . url) ;

Note from the Author or Editor:
On page 263, please change: println("100th ARTICLE URL: " + r. articles[ 9] . url) ; to read: println("10th ARTICLE URL: " + r. articles[ 9] . url) ; In other words, "100th ARTICLE URL" is changing to "10th ARTICLE URL".

Figure 18-9

Text on the previous page says that MRI is better than DSCT for children. If this is correct, Figure 18-9 should show an MRI image than DSCT one.

Note from the Author or Editor:
The text is correct, but misleading. On page 316 please change the reference (Figure 18-9). to (Figures 18-9 and 18-11). Thanks!
