Hello, The textbook seems nice and clear. The only nitpick i have is that it should talk more about equations of state. I understand that it may not be the focus of the text, but m…

some constants that may or may not be transcendental: - Percolation Thresholds: https://en.wikipedia.org/wiki/Percolation_threshold - Critical scalings in 3d: https://en.wikipedia.…

That is one thing i like about the Julia package ecosystem. The general Registry (where package metadata is stored and where you go to register a new package), recommends using exp…

It seems like this uses DWSIM under the hood for the simulations? Cool project

_ is for Alphabet

a 3-meter high wall of water is not really good either, due to kinetic energies, if no significant tsunami coastal protections, that water flow can reach far inland

CORBA is used in the chemical industry (CAPE-OPEN standard) https://www.colan.org/

i don't use Erlang (mainly Julia), but this change makes a lot of sense. in Julia, there is the == operator (value equality) and the === operator (value egality). 0.0 == -0.0,becau…

i don't think so

tianqi sold all his shares of SQM (one of Chile lithium companies, around 23%) after the announcement. The situation of the lithium in Chile is very particular. in the Pinochet dic…

"Fun" fact about that, it was nationalized because it is a material for use in atomic bombs, in the 70 and 80 there wasn't another use for large scale lithium mining, except for th…

seems vaguely like McCornick relaxations? https://optimization.cbe.cornell.edu/index.php?title=McCormi...

well, thermo is from the greek word thérmē meaning heat. we use the termo- suffix for all things that involve heat (thermodynamics -> termodinámica, thermometer -> termómetro)

I suppose that Twitter has to pay each time a SMS is sent (ar at least, they pay according to the amount of SMS generated), so the bots pump that amount?

grande messi!

for instagram, i just gave up looking at the feed and just look at the posts that a group chat sends

yeah, my systems are really small in comparison (1-20) but with higher order derivatives (up to 4th order), so reverse AD is not the best in that regard

I feel called out on the academic part hahaah. I simply want to code state of the art (thermodynamic) models, and at least julia helps by providing easy testing and publishing infr…

Of course! we are urgently in need of a "critical boiling" relation. At the moment we are using critical isochores as a way to "extend" the saturation curve, but it is less than id…

We have a solver for the pure critical point, that just finds the (v,T) coordinate that satisfies dP/dV = 0 = d²P/dV². of course, not all EoS can even satisfy this condition. Cubic…

A lot of new work on supercritical fluids is the ability of calculate properties for those. normally we don't access to those conditions, so it is tricky to measure, but there is a…

i'm working on calculating thermodynamic properties from equations of state [1], and yeah, looking for criteria on how to distinguish from a low pressure, a near critical pressure …

The Julia equivalent does a good job explaining the 0.0 case: https://docs.julialang.org/en/v1/base/math/#Base.isapprox

In Julia at least, there are packages that provide alternatives to Bigfloats: Logarithmic numbers: more range, less precision https://github.com/cjdoris/LogarithmicNumbers.jl Doubl…

I like the discrepancy of technology presented in that counterexample. Euler definitely didn't Have that amount of computing power to just do a naive search,now we can even do thos…
