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 mentioning the current state of equations of state (SAFTs, cubics, multiparameter) would help guide readers looking on how to generate their own steam tables for their fluid of interest, even if the advice is just "go use CoolProp"

On the other hand, i really like the ilustrations on turbomachinery, helps ground the theoretical content.

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 explicit names over short acronyms. For example, DifferentialEquations.jl is a package that does differential equations in julia (recognizable via the .jl suffix). What does Garlic.jl do? Exactly, garlic (the vegetable) modelling.

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

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

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,because they have the same "value". but they aren't identical (the bits are different), so !(0.0 === -0.0).

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 dictatorship, litium was nationalized, because it was a key ingredient of atomic bombs (and not much else at that time), and USA didn't want other countries to access the resource, so all current mines are in a lease contract (Albemarle until 2043, SQM until 2030). the new proposition opens new zones for exploitation, in exchange of the public-private parnership

"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 that

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?
