Some people think they can tell if a part broke due to hydrogen embrittlement by looking at it. This is not correct. The timing of the crack is only one of the key factors that needs to be documented if hydrogen embrittlement is suspected.
The great scientist Niels Bohr, to whom we pay homage when we talk about “The Bohr Atom,” famously pointed out that great truths, such as “Democracy is the best form of government,” are often refuted by “opposite” great truths.

If you are helping others solve technical problems, deep knowledge in the advertised subject matter is required. Communication skills serve as one example of a crucial additional area of required expertise.
