The first sentence, "The information transforms in the brain are made yet more complicated by the constraints...." doesn't make sense.

should be:
"...but it also means that they don't always respond how you would have thought when you try *to* influence them."

3rd paragraph |
The method for calculating the century-item adjustment for Gregorian dates is
incorrect, since 5 mod 7 = 5, not 0. If we had used the proposed method and
calculated 5 mod 7 correctly, then we would actually get:
20 / 4 = 5
5 mod 7 = 5
3 - 5 = -2
2 * -2 = -4?
Obviously this does not yield the result in Table 4-11, p. 166. If we omit the
modulo operation and replace the division with a modulo 4 operation, then we do get
the results in Table 4-11:
1700s:
17 mod 4 = 1
3 - 1 = 2
2 * 2 = 4
1800s:
18 mod 4 = 2
3 - 2 = 1
2 * 1 = 2
1900s:
19 mod 4 = 3
3 - 3 = 0
2 * 0 = 0
2000s:
20 mod 4 = 0
3 - 0 = 3
2 * 3 = 6
2100s:
21 mod 4 = 1
3 - 1 = 2
2 * 2 = 4
2200s:
22 mod 4 = 2
3 - 2 = 1
2 * 1 = 2
2300s:
23 mod 4 = 3
3 - 3 = 0
2 * 0 = 0
In general, perhaps the author meant, "To get the century-item for any Gregorian
date, cast out fours, subtract the result from 3, and multiply the difference by 2."
Or, in rough mathematical terms:
2 * (3 - (C mod 4))
where C is the century, such that C = 20 for the year 2005.
