The exponential function has the remarkable property that it is the unique function f that satisfies the differential equation f'(x) = exp(x) with initial value f(0)=1.

Well, it's within Germany so I travel by train and that's as safe as the trunk of any car I'd say

I also needed assistance by some Minecraft-savvy guy. Unfortunately I don't remember how that worked

Omg my daughter just passed the reverse Turing! But now she's stuck at the chess level

Oha, das ist übel

Or was it "yourself" with some glitter around?

I think we passed by just writing "self"

Darauf hat man als Prof eigentlich gar keinen Einfluss - das entscheidet die Personalabteilung. Manchmal habe ich versucht, eine höhere Einstufung zu erreichen, aber da ist selten was zu machen

19 to the right and 10 down

I tried again and finally got to level 42! It's a reverse Turing and it really feels like it's not meant to be passed

Das ja. Ich dachte es ginge darum, dass Profs Vorteile dadurch haben, dass nur befristet anstellen.

Als Prof sehe ich für mich auch keine Vorteile darin, dass alle Verträge befristet sein müssen. Befristetes Projektgeld ist eine Sache, aber dass auch Uni-Geld nur für befristete Verträge geht ärgert auch mich.

📢 #ISMP2027 comes to Amsterdam!

The 26th International Symposium on Mathematical Programming will be held July 25–30, 2027.

Join researchers from around the world to discuss advances, challenges, and opportunities in the theory and practice of mathematical optimization.

Am I right that a function that is not increasing and also not decreasing is in fact just creasing?

After reading on MPS files, I say that there are several things about them that are misleading! (They don't know if the problem is about maximizing or minimizing! If you specify an upper bound and no lower bound is the lower bound of zero still used? What if I specify a lower bound of -1?)

I for one don't know what an MPS file even is. In a package like scipy that is for a general audience in scientific computing it is definitely confusing.

Most people in everyday life wouldn't call a straight line a convex function (most people wouldn't speak about functions anyway, but well...).

(Sorry for reviving this, just appeared in my timeline again)

And bound=none makes this abundantly clear - got it!

So you tell me that when I call scipy's linprog with bounds=none, it uses a lower bound of zero?! Yeah, that makes a lot of sense #scipy!

"me rest for a little longer" maybe?

Curious! Could you elaborate a bit on the way Sturmfels does math collaborations?

Truly an outstanding achievement!

A dark blue celebratory graphic marking the 5-year anniversary of Her Maths Story. The HMS logo appears at the top. Large white text reads “5 years” in the centre, surrounded by yellow star shapes. Additional text highlights milestones: 99 contributors, 200K website visitors, 194 countries reached via the website, and 4.9K followers across social media platforms.

5 years ago today, Her Maths Story went live with our 1st story. What started as a small idea has grown into a global, supportive community celebrating #WomenInMaths. We’re deeply grateful to everyone who has shared, read, supported & believed in this journey. Here’s to the stories still to come 💛✨

Is this even possible administration-wise? Where I am the administration needs at least six weeks between agreement and signature of the contract...
