#MathSky: Is it okay to email a copy of one of my papers to an editor of a journal to ask if they think it might be a good fit before submitting it to that journal?

RIP, Richard Tapia! I recall his recounting of his mother's teachings & I hope that I can continue to live by them, just as he did: 1) Be proud; 2) Believe that you can (sí se puede); 3) Demonstrate good work habits; 4) Strive for global excellence. Richard's testimonio: shorturl.at/7KYjK #MathSky

We are hiring in Operations Research at @hmc.edu! If you or someone you know is on the job market, please consider applying: math.hmc.edu/tenure-track...

Today was our last day of our research experience and I am extremely proud of my summer research students @hmc.edu! Group one (Tito Cuchilla ‘26, Joseph Hound @claremontgraduateu.bsky.social, Cole Plepel ‘27, Louis Ye ‘27) Group two (Cameron Ake ‘28, Spencer Lewis ‘28, Amanda Louie ‘28)

New preprint announcement! This is my FIRST paper with @hmc.edu students and a @claremontgraduateu.bsky.social grad student! Very proud of this paper and the students who worked with me this summer. “Equivariant volumes of symmetric edge polytopes” arxiv.org/abs/2507.18846

ok i am aggressively not a sports person, but this story by @dodecalemma.bsky.social is so cool! and the graphics were fun to work on :) www.scientificamerican.com/article/the-...

Squirrels LOVE octahedra.

What is your favorite shape & why? For HMC math prof @arvm.bsky.social it's a permutahedron, a symmetrical, convex polytope that exhibits many special properties. Read more about Vindas Meléndez's favorite shape & the key it holds to big mathematical mysteries on @sciam.bsky.social. uqr.to/arvm-sm.

Yuan Zhou talks at the #mip2025 about how to estimate the solid angle of d-dimensional cones, which corresponds to the proportion of Rd occupied by them, and which does not has a known closed formula for d > 3. 1/N

Seems like today was a good day to be too busy to check social media during work hours

#MathSky there's a new online open-access (and free) journal for mathematics and fiber arts: Interlace. Now accepting manuscripts! Editors-in-Chief: sarah-marie belcastro and Carolyn Yackel. 🧶 www.interlace-journal.org

Happy Star Wars day! May the Fourth be with you! foxtrot.com/2025/05/04/a...

New release of 4ti2, the package for algebraic, geometric and combinatorial problems on linear spaces. This is a maintenance release with no new features. github.com/4ti2/4ti2/re... #FOSS #MathSky

New paper with awesome collaborators! "The Ehrhart polynomial of a matroid specializes to the beta invariant" with Anastasia Chavez (SMC), Galen Dorpalen-Barry (Texas A&M), Luis Ferroni (IAS & UniPi), Fu Liu (UC Davis), and Felipe Rincón (QMUL). #mathsky arxiv.org/abs/2504.15518

HMC mathematics professor @arvm.bsky.social has co-authored a paper on polynomial properties in polyhedral geometry. Read the full article about Vindas Meléndez's paper on the behavior of local h-polynomials on our news page. uqr.to/hmc-arvm.

Profs. @haydeelindo.bsky.social, @jamiehadd.bsky.social & Talithia Williams share the Institute for Data Science and Social Impact, which will foster interdisciplinary collaboration, advance data science research, & create pathways to apply data-informed methods to real-world issues. uqr.to/iap-dssi

HMC mathematics professor @jamiehadd.bsky.social has been awarded a CAREER grant from the NSF. The grant supports Haddock's desire to be a mentor and increase access in data science for groups that have been historically excluded from research mathematics. uqr.to/haddock-career.

This week, I recorded 4 new #VisualAlgebra YouTube videos on group actions. I heavily use the following concepts: 1. G-sets 2. Action graphs 3. Group switchboards 4. Fixed point tables. Interested? I'll give you a preview here. Please share! #MathSky 🧵👇1/16

My submission for Day 15 of @ayliean.bsky.social's #MathArtMarch: Triangle!

My submission for Day 17 of @ayliean.bsky.social's #MathArtMarch: Symmetry!

It’s me 😅 Love the math I get to do with amazing collaborators! www.hmc.edu/about/2025/0...

Today would have been the 104th birthday of Brazilian mathematician Marília Chaves Peixoto, the 1st woman in Brazil to earn a PhD in math, and a researcher into the conditions for stable fluid flow over a surface. She passed away in 1961 at the age of just 39. #WomeninSTEM #MathSky #HistSci 🧪🧮

A dear friend wrote a thing about me. Thank you, @yarntheory.bsky.social, for this post but mostly for your friendship. ❤️

My friend @mathyadriana.bsky.social lost her job last week, and I want you to know the story: buttondown.com/yarntheory/a...

Me🤦🏻‍♂️: name’s not correct in the doc. My last names are V_ M_ & only shows M_ Tax assessor: I took name from deed 🤦🏻‍♂️: That has my FULL name T: *checks deed* you should’ve hyphenated. I’ll change it if you insist 🤦🏻‍♂️: No I shouldn’t have bc my name has NO HYPHEN. Yes I insist because I want MY NAME.

Last night I found out that the NSF math postdoctoral fellowship I applied for is being deleted because it does not comply with Trump’s executive orders on DEI in the federal government. I’m going to answer some FAQs and share some thoughts about this ordeal in this thread 1/n

Y’all they cancelled the NSF MPS Ascend Program after encouraging underrepresented folks to only apply to it and not both the Ascend and the MSPRF. This is astronomically fucked up for many grad students and postdocs of color in math. #MathSky

Sent an email You can too #Mathsky

Happy Black history month, friends! Did anyone else notice that the AMS Notices completely ignored Black history month this year and (by my count) there is only one article in the entire February issue that is even coauthored by a Black mathematician? #MathSky

No matter where I am, at home or in the classroom, I am anxious and in constant fear for my undocumented family, for my trans family, for me, my partner, and all my queer family. …then I get to my office and am also like, “can someone just tell me if I can or cannot apply to this f*$king grant?”

Excited to see this paper finally appear! It's a review of the field we are calling "the mathematics of mathematics", a subfield of Science of Science but specifically applied to mathematics (broadly construed). With @ronbuckmire.bsky.social @nativemath.bsky.social @arvm.bsky.social et al.

Two justice oriented panels at #JMM2025 happening Wednesday (I’m moderating one of them): The Mathematics of Mass Incarceration How Can the Mathematical Community Mitigate Bias and Other EDI Issues in Al Unfortunately they’re at the same time but right next to each other.

Just wanted to share this course eval ”gem": <I would have changed the professor, attending other professors were more prepared to teach the course. HOWEVER: on a human level I appreciated the vibe of the professor, I just think he should teach a different area of math. :D > #mathsky
