Fact Check: "Gilbert was mortally wounded in the same attack that killed his owners."
What We Know
The claim regarding Gilbert being mortally wounded in an attack that also killed his owners lacks substantial evidence from credible sources. The sources available primarily discuss Gilbert Strang's textbook on linear algebra, specifically the "Introduction to Linear Algebra" (5th edition), which does not pertain to any incidents involving a person named Gilbert or any attacks. The first source mentions the textbook as a comprehensive introduction to linear algebra, while the second source references a specific mathematical conclusion found within the same textbook, but neither source provides any context or information related to the claim about Gilbert being wounded or involved in an attack (source-1, source-2).
Analysis
The claim appears to be unfounded based on the information currently available. The sources cited do not discuss any events involving violence or injury related to a character named Gilbert. Instead, they focus on educational content, specifically related to linear algebra. The lack of relevant information in these sources raises questions about the credibility of the claim.
Moreover, the sources are from Zhihu, a Chinese question-and-answer website, which may not be the most reliable for verifying claims of this nature, especially if they do not pertain to the subject matter at hand. The absence of any corroborating evidence or reports from more authoritative sources (such as news articles or academic publications) further supports the conclusion that this claim requires more investigation.
Conclusion
Needs Research. The claim that "Gilbert was mortally wounded in the same attack that killed his owners" lacks supporting evidence and credible sources. The available information does not address the claim, and further research is necessary to determine its validity.
