Classic floating-point quirk:
0.1 + 0.2 == 0.3 # false
Julia: use ≈ instead.
0.1 + 0.2 ≈ 0.3 # true

Is it open to International students who are currently studying at their own countries?

Assume gains are private, but losses are shared. What happens if this rule governs a system of interacting open subsystems exchanging resources with the environment? The system will have a sharp, switch-like state transition. Check our new pre-print arxiv.org/abs/2512.22839

An increasing number of UG students appear to be struggling with mathematics. What we thought was a local, transient issue may actually be part of a wider, possibly global, problem.

In Julia, function composition isn’t just notation… it's executable math

> f(x) = x^2 + 1
> g = f ∘ sin
> g(pi/2) # gives 2

‘This hurts’: NU regents back shuttering four academic programs at UNL • Nebraska Examiner The University of Nebraska Board of Regents voted to eliminate four academic programs at the University of Nebraska-Lincoln.

A university is closing its Department of Statistics due to financial constraints. Really? In this age, where mathematics, computing, and AI/ML dominate every industry, closing a Statistics Department doesn’t seem like a good business decision. #justsaying nebraskaexaminer.com/2025/12/05/t...

To what extent can the foundations of thermodynamics & stat physics be built purely from combinatorics and probability—without relying on the usual concepts like work, heat, and energy? Are there any textbooks that develop the theory primarily from a probabilistic perspective only?

Don't be clueless! Better, understand how Julia thinks:
@code_lowered 2 + 3
@code_lowered 2 + 3.0
@code_lowered 2.0 + 3.0

Code better. Code smarter.

Why burden memory? Take a sneaky peek and get the job done!

A = rand(5,5)
W = @view A[2:4,2:4] # take a peek, no copying
@views W[1:2, 1:2] .= 0 # sneakily mutate
A # check the mutation

Schrödinger’s cat called. It is live and it wants a break. It didn’t sign up to explain superposition to every social media users. Enough!

Using ± in Julia code? Yes, because real models don’t come with exact parameters.

k = 1.0 ± 0.1

Temperature is not just a thermometer thing. Physicists, chemists, biologists, economists, and data analysts all use it differently. Maybe one day we'll find a single rule that links them all. Until then, temp keeps its cool by being complicated.

Many bugs don't scream. They whisper in wrong units. Using units in your code can save you. Again, Julia helps in that.

using Unitful
D = 0.01u"mm^2/s" # 0.01 mm^2 s^-1
t = 100u"s" # 100 s
√(2D*t) # 1.4142 mm

Identical genome. Same environment. Totally different life choices. Turns out even cells have an identity crisis. #sysbio #physicsoflife

I get confused when philosophers and scientists debate “reality.”
If I slap someone, they feel pain and may hit back. That’s real.
So clearly, I’m missing something much deeper. #justsaying

In biology, we’re still busy naming T cells and debating EMT or autophagy — a bit like arguing over bird names while the real wonder lies in understanding how they fly.

Dear developmental biologists, Julia comes with a Zygote that auto-differentiates. 😀

Metareview: a survey of active matter reviews - The European Physical Journal E Abstract In the past years, the amount of research on active matter has grown extremely rapidly, a fact that is reflected in particular by the existence of more than 1000 reviews on this topic. Moreov...

At the beginning of this year, Active Matter researchers published a 'review of reviews' — yes, a meta-meta study. When your field grows so fast, you need a map of the maps. Worth bookmarking.

Is it weird that I prefer old biology papers—the ones with two figures, zero rainbow plots, and actual ideas? Or am I just allergic to 100-page supplements that explain nothing?

Every time I get overwhelmed, I remember- a lot of statistical physics is basically fancy bookkeeping for balls in boxes.

When science books cost a fortune, only publishers win. Open sharing—GitHub, arXiv—helps every learner. Isn’t it time to free ourselves from the 'medieval' prestige of being ‘published by a reputed publisher’? #scicom #edu #doingsciencd

Wet lab? Dry lab? I prefer the Symbolic lab.
Math-Bio isn't just HPC runs— derivations & proofs matter too. As always, Julia helps.

Calling any large, well-organised dataset "Systems Biology" is a bit like calling a census "social theory." Essential, powerful, and impressive — yes. But the explanations, through generalised theories/models, still have to be earned. #systemsbiology #sysbio #physicsoflife

@ricardsole.bsky.social Is not 'thinking' (that we do) also just obeying 'physics'- possibly a physics we don't yet know or understand? #justcurious

PhD defense (Dramatized based on real events):

You (examiner): That statistics & conclusion are wrong. Needs correction for repeated tests.

Candidate: 🤔 (flustered).

Supervisor: No issues! 😡 This work is already published.

How often do you face such a situation?

Writing code using symbols in Julia feels like scribbling in a math notebook — except this one actually runs. It takes some time to get habituated, but then you get hooked.
