The following are some mistakes made by AI.

AI apparently does not know the difference between the follow two snippets of text:

1. the sample with added HDMS

2. the sample with HDMS added

The first snippet of text says that the sample initially contains HDMS and more HDMS is added to it. The second snippet says that the sample initially contains no HDMS and that HDMS is added to it.

AI changed the following TeX code

\(\gamma_{n,\text{in}}{\rm s}\)

to

\(\gamma_{n,\text{in}}\ {\rm s}\).

Can you spot the error that completely changes the meaning?

Consider the following text:

This is called “stress relaxation,” and the ratio of stress before to that after the stress-relaxation period gives the stress-relaxation ratio.

AI suggests changing "to that" to "and," which produces two undefined ratios instead of one well-defined ratio.

Stay tuned for more examples of bad AI.
