We should keep in mind that Hydrogen “embrittles” many metals and cause failures through cracking.

We should also keep in mind that today’s “Snowflake” college engineering students do not have to take a required “Failure Analysis” class their senior year.

We should also keep in mind that the lowest grade that an engineering student can get is a B rather than an F.

Give a university science student a B+ rather than an well deserved F and it is highly probable that the student’s parent will call both the class instructor and University Vice President and threaten a lawsuit.
