The creator of the fabulous math site purplemath.com passed away last year, I think. I read the news in another math site.
Elizabeth is her name. She will be missed. A great mathematician she was.
In addition, I think my friend MarkFL has also passed away. He was diagnosed with a rare terminal form of cancer in the summer of 2023. I haven't heard from Mark since the summer of 2023. He was given 6 months to live. If he passed away, Mark was a great math contributor to many forums and a good friend to me.
Lastly, I think retired math professor by the username Soroban has also passed away. He was 75 years old in 2006. If he is alive, 94 would be his current age. How many people in the United States live beyond 90 when the current lifespan is 74 years old?
