Maria Gaetana Agnesi's 306th Birthday

I'm happy to see Maria Gaetana Agnesi's birthday acknowledged in today's Writer's Almanac. However, the article is a bit misleading and includes at least two myths that I have debunked here before:

1. She did not invent or discover the Witch of Agnesi Curve
2. Her mother's death did not keep her from becoming a nun   

As a former newspaper journalist, I'm very annoyed when publications get the facts wrong, especially when I've notified them of their errors in the past. I guess all I can do is continue to point out the mistakes here.  

Meanwhile, I'm pleased to report that earlier this year, in honor of Women's History Month, the American University Library shared an Instagram post about Maria, noting that:

"In our rare books collection, we have a first edition of the English translated work of the Italian mathematician, Maria Gaetana Agnesi."

Celebrating Maria's Birthday with Another Honor

Today is the 305th anniversary of the birth of Maria Gaetana Agnesi! I'm happy to share that she received another honor just last month: a satellite named for her. 

On April 14, 2023, Satellogic Inc. deployed four new satellites named for women in STEM, including one honoring Maria. Here is an excerpt from the Satellogic, Inc. announcement:  

The SpaceX Transporter-7 mission was completed Friday, April 14, with a two-stage rocket delivering the four satellites designed and built by Satellogic to orbit. The NewSat Mark-IV models include multispectral cameras designed to collect high-resolution imagery from sun-synchronous low-Earth orbit. Satellogic continued its celebrated tradition of naming satellites after remarkable women in STEM and has named these four spacecraft after Joan Clarke, Annie Jump Cannon, Tikvah Alper, and
Maria Gaetana Agnesi.
For the complete list of the women honored to date, see this page of the Satellogic website.

Happy birthday, Maria!

International Women in Mathematics Day and Maria Gaetana Agnesi's Birthday

Monday, May 16, 2022 will be the 304th anniversary of the birth of Maria Gaetana Agnesi. I'm posting a couple of days early because I just learned of another, related, celebration that I missed two days ago on May 12: International Women in Mathematics Day

According to this article, the date of May 12 was chosen in 2018:

". . . in honor of Iranian mathematician Maryam Mirzakhani, born on May 12, 1977, and the first woman to win a Fields Medal, the highest award given by the international mathematical community."

Sadly, Maryam Mirzakhani died in 2017 at age 40. She is included in this article listing 14 "Amazing Women in Mathematics."  Maria Gaetana Agnesi is also on the list. I find it interesting that these two women shared May birthdays along with their love of math.

Sharing Another Monument to Maria on International Women's Day

On May 16, 2017, the 300th anniversary of Maria Gaetana Agnesi's birth, she was featured as the "Scientist of the Day" on the Linda Hall Library website. The article, which was written by Dr. William B. Ashworth, Jr., Associate Professor, Department of History, University of Missouri-Kansas City, includes several interesting photos related to Maria and her life. The final photo is a bust of Maria that is featured on the side of Milan's Palazzo Brentani:

Maria Gaetana Agnesi. Detail from the series of decorative busts (portraying "distinguished Italians") on the facade Palazzo Brentani, in via Manzoni street at Milan. Picture by Giovanni Dall'Orto, April 14 2007.

Here's Professor Ashworth's description of the bust:

"The Palazzo Brentani in Milan has a series of 18 portrait plaques that circle the exterior, celebrating important citizens of Milan. Front and foremost, right over the entrance, is Leonardo da Vinci ... , but in the second-best spot, just to the viewer’s left of Leonardo, is a plaque for Agnesi ...."

I'm highlighting the image here today in honor of International Women's Day and Women's History Month. This is the perfect time to remember Maria Gaetana Agnesi and all the other unsung women of history.

New Adult Nonfiction Featuring Maria Gaetana Agnesi

I want to post one more quick update to make sure the new email subscription service is working properly. So I'd like to share the title of a new book for adults that mentions Maria Gaetana Agnesi: Forces Of Nature: The Women who Changed Science by Anna Reser and Leila McNeill.

A review in the Albuquerque Journal said "The volume has the heft of a textbook, but it’s a readable history."  I look forward to reading it soon. If you get to it first, let me know what you think.

Quick Fun Fact About Maria Gaetana Agnesi

I usually post about the myths associated with Maria Gaetana Agnesi and her family. But today I thought I'd share a fun fact: there's a crater on Venus named in Maria's honor. While I couldn't find a good image of the crater to share, here's one of the planet Venus:


You can read more about the crater here.

According to the MacTutor site, two other female mathematicians have Venus craters named for them: Émilie du Châtelet and Sophie Germain.
