A polynomial of a sufficiently high degree? :D

Have you ever wondered what narwhals and blessings have to do with viscoelastic flows? Our latest preprint has it all :)

arxiv.org/abs/2509.03175

Narwhals and their blessings: exact coherent structures of elastic turbulence in channel flows

Solutions of long, flexible polymer molecules are complex fluids that simultaneously exhibit fluid-like and solid-like behaviour. When subjected to external flows, dilute polymer solutions develop ela...

Sure. Objective is an adjective. Now you need a noun.

Looks amazing! Shame I could not be there.

I would simply pay them in bottle tops and see whether the penny would drop.

I guess when areas do not have units, budgets do not need to balance either…

Alexander Morozov @alexandermorozov.bsky.social · Jun 24

According to Financial Times, this puzzle was used by Dominic Cummings to select ‘innovators’ and ‘disruptors’ to work for the British Government.

I guess when areas do not have units, missing a few zeros in one’s budget is not such a big deal…

Out today in Phys. Rev. Research, we ask "how does an active nematic fluid respond to a deformable body or boundary?" We were pretty amused by a few observations. 1/20

Happy to share our recent preprint on (the absence of) giant number fluctuations in microswimmer suspensions.

arxiv.org/abs/2503.18068

Pseudo-giant number fluctuations and nematic order in microswimmer suspensions

Giant number fluctuations (GNFs), whereby the standard deviation $ΔN$ in the local number of particles $\langle N \rangle$ grows faster than $\sqrt{\langle N \rangle}$, are a hallmark property of dry ...

Some pictures from yesterday’s Wim-van-Saarloos-70-fest at the Dutch academy @knaw-nl.bsky.social. Happy birthday, Wim!

NB it’s the same room as where Pauli received his Lorentz medal.

Mooie dag vandaag bij de @knaw-nl.bsky.social. Oud-voorzitter Prof. Wim van Saarloos is vandaag 70 geworden en hij wordt geëerd met een symposium.
Wim heeft enorm veel bijgedragen aan de natuurkunde en aan de NL wetenschap in het geheel.
Van harte, Wim!
