ACMS Updates

The following info was recently sent to members of the ACMS.

1. 2023 Joint Math Meetings Reception – ACMS will once again be hosting a reception at JMM. The reception will be from 6-7:30 PM on Thursday, January 5th at the Marriott Copley Place, Salon G . Karl-Dieter Crisman (Gordon College) will be our guest speaker and his talk will be from 6:30-7 PM. At the conclusion of his talk, we will break out into small groups for dinner and discussion at various local restaurants. Please contact ACMS Vice President Kristin Camenga with any questions.

Abstract for Karl-Dieter Crisman’s talk:

Mersenne Matters: Mathematics, Music, Monotheism, and More

Marin Mersenne is usually considered, when he is considered at all in mathematics, in one of two ways. Either he is the inspiration for the latest newly discovered (and enormous) “Mersenne Prime,” or he is the interlocutor who helped induce Fermat and Descartes to properly, and “publically” discuss their methods of tangents.

But who was Mersenne, what did he do, and why does he matter? This talk will give an overview of his life and the important roles he played in the history of science and music, with many examples from his own writings. We’ll especially look into why a monk, from an order devoted to being the least of all, saw his explorations of things like pure mathematics and practical acoustics as being so closely related to his writings in defense of the faith.

2. Dues Updates and Price Changes – The board has voted to raise the annual price of dues from $20 annually to $30 annually. This change will take place March 1, 2023. You are welcome to pay your 2023 dues, as well as pay in advance for future years, at the current rate any time before March 1. If you have any questions regarding your current dues status, please contact ACMS Executive Secretary Mike Janssen.

3. Brabenec Lectureship – Dates and locations have been determined for the inaugural Brabenec Lectures to be given by Russ Howell. March 13-16 Russ will be making stops at Huntington, Taylor, and Indiana Wesleyan. March 23-24 Russ will be at Lee University. Thank you to all the schools who applied to host Russ. Look for an email in the new year (around February/March) providing details on Russ’s talks as well as an application/nomination process for the ’23-’24 Brabenec Lecturer. The board plans on a rough timeline of announcing the next lecturer around Memorial day, a mid-July deadline for schools to apply to host, and announcing the host schools in August. Again, look for more information starting in February/March of 2023. 

4. Application for Hosting the 2026 ACMS Conference – As we look forward to the 2024 conference at Dordt, we are beginning the process of accepting applications for a 2026 host. Please complete this form if you are interested in hosting. In keeping with the geographic rotation of each conference (APU 2022 – west, Dordt 2024 – central), preference will be given to schools considered “east.”

5. Consider Donating to ACMS – please consider donating to ACMS. ACMS is now recognized as a 501(c)3 non-profit and can offer the tax benefit of donations. Visit us online and click the “Donate to ACMS” button on the right hand side bar.

John Roe (1959-2018)

At the end of March I was saddened to learn of the passing of John Roe, a professor of mathematics at Penn State University whom I had gotten to know through the Association of Christians in the Mathematical SciencesJohn moved from England to the United States in 1998 to join the math faculty at Penn State University.  Even while he was still in England, John was a ACMS member, but after his move to the US, he became increasingly active, attending the summer conferences, serving as a Board member, and speaking at one of the joint meetings receptions.
From the opening lines of his obituary:
John Roe — mathematician, teacher, rock climber, theologian, activist, and follower of Jesus — has departed from family and friends as well as the pain of cancer and has begun “a more focused time of peace and joy” with his Lord.
I felt blessed every time I interacted with John. Below is an excerpt from a post on the 20th ACMS Conference:
20th ACMS Conference Day 2

The day began with another excellent devotional from John Roe (who has graciously contributed his thoughts on in the past). Personally, I feel blessed after every time I hear John Roe speak – he just has a way about him that seems infused with grace and deep spiritual understanding. John led us through Ephesians 3:14-19 with particular focus on the four dimensional analogy used by Paul:

For this reason I bow my knees before the Father, from whom every family in heaven and on earth is named, that according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being, so that Christ may dwell in your hearts through faith—that you, being rooted and grounded in love, may have strength to comprehend with all the saints what is the breadth and length and height and depth, and to know the love of Christ that surpasses knowledge, that you may be filled with all the fullness of God.

Some of John’s points:

  • When thinking of the love of God, don’t think in abstractions. Think of the concrete. Think of the cross.
  • Wideness – if you fold your arms across your chest this is the typical position of religion; inclusive and safe. If you stretch your arms wide open this is the position of Christ on the cross.
  • Longness – (a dimension of time perhaps) God’s patience and love are endless. God’s love wins because it endures more than we do.
  • Highness – The son of Man was lifted up. Christ does not shrink from being on display in that shameful place; He doesn’t hide.
  • Deepness – How deep Christ went – down to earth, down to the grave. How deep in our own hearts are the places that He can reach. He went there and He proclaimed freedom there.

To me, John Roe was a concrete example of the love of Christ. He will be missed here on earth but we rejoice in knowing that he is in the presence of his savior.

All to the glory of God
Succeed at home first
Communicate every day
Seek the heart of worship
Move out of the comfort zone
Teach from the heart
Prepare the ground for insight
Start with what matters most
Love alone endures
