Democracy is the best system of government. I personally believe this is true, because democracy generally gives a greater proportion of the population the chance to try out their ideas than do authoritarian systems.

It can be tough to figure out where to start in the quest to understand problems. How can we develop the ability to move ahead?
By developing clear thinking. However, these four words don’t help anyone acquire that skill.

Keep up with Debbie Aliya's blog series "Recognizing Facts and Sorting Things Out." Here's part 4.

Western philosophy didn’t really start grappling with such concepts until another German philosopher, Immanuel Kant (1724-1804), came on the scene. Schopenhauer’s work took up where Kant left off. He reinforced some of Kant’s ideas, and weakened others. 

The attempt to categorize “things” goes back a long time in the history of human ideas, but I have found the work of three people to be the most helpful in structuring my own version of this knowledge. 

Recognizing a fact is a tough task. In casual conversation with friendly people, we don’t need to get stressed out about the words coming out. If I state that “I am wearing a long-sleeved shirt and jeans,” anyone who looks at me directly, at this moment, sitting at the desk in my office, would be able to determine right away if that is a fact or not. Anyone who knows, at least, what a long-sleeved shirt and jeans are and knows “who I am.”

There are two basic answers that can always, or almost always, apply to anything that “failed.” These two basic answers are almost always true.

An additional consequence of the “counterfeit bolt scandal” was that most of the people in the industry learned that the bake had to be within one hour of the parts exiting the plating bath.

Historically, hydrogen embrittlement was thought to be confined to parts over Rockwell C 39. In my experience, small electroplated parts over Rockwell C 43 seem to populate the ranks of hydrogen-embrittlement-related cracks at a significantly higher rate than those between 39 and 42. This is a problematic statement since the Rockwell C test method accuracy is generally considered plus or minus 2. This is my experience, so I am reporting it. 

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. Four more will be listed in this blog series.
