The only known way to stay sane in the business.

I really congratulate you on how you preserve and celebrate the British railway. It is a magnificent heritage and a sign of progress in all societies.

I remember playing Microsoft Train Simulator and it was fantastic. I remember the Flying Scotsman.

Unfortunately, in my country the work of the English on the railway has not been valued and things have ended quite badly.

Thank you for those words Matias, much appreciated. UK benefitted from many events during the Industrial Revolution, technology, materials, education. Not least the Victorian age, when science and engineering were celebrated.
The railways also benefitted from geography, Coal, Iron were all locally available. A small island mostly North/South, not much East/West, so a lot of downhill routes...

If I get the buzz right, this paper suggests that we had to make up dark matter because we treated the universe as a spherical cow in a vacuum, and it's not required if you consider the actual shape of the cow:

It's all completely above my paygrade, obviously, so I can't really recommend or not recommend the paper, other than that I had a gut feeling for quite some time that there must be a more reasonable explanation than "magic invisible pixy dust"...

OTOH, in the GR/QG literature, many of the things you can do to make gravity deviate from GR (such as introducing a massive graviton) introduce some kind of cosmological constant term (at least in semiclassical approximations, given that QG itself is a magnetically intractable problem at the moment), so it doesn't really require magic pixie dust, just that quantum corrections to GR introduce one of a fairly broad range of features that could cause such an effect.

Also, recall that just the ground state energy of the standard model, in a semi-classical approximation, introduces a cosmological constant that is much larger than putatively observed if we assume that it gravitates.

The name "Dark Matter" is a confusing the name, because it sounds like "mysterious dark stuff".

Dark Matter is not some mysterious dark stuff, that is there to balance an equation. It goes a bit deeper.

All "Dark Matter/Energy" is, is: "The solution to the observations".

What we observe, looks exactly like what we'd expect, if there were a bunch of mass that we had no way to observe. But, there is no implication that yet-unobserved mass is the solution. To quote Angela Collier, "Dark Matter is not a Theory". It's a problem.

Stroustrup: How many errors due uninitialized variables you want?
C++: YES!

And today using Valgrind debugger, I stumbled upon this comical error message:

==89687==
==89687==
==89687== More than 1000 different errors detected.  I'm not reporting any more.
==89687== Final error counts will be inaccurate.  Go fix your program!
==89687== Rerun with --error-limit=no to disable this cutoff.  Note
==89687== that errors may occur in your program without prior warning from
==89687== Valgrind, because errors are no longer being displayed.

Today I went on the Internet, and I found this: I had a vague memory of having a sort of CD Encyclopedia by Rizzoli, an Italian publisher, as a kid, but sadly that CD most likely got thrown out many years ago when tidying up.

But the Internet Archive exists, and there I found this, which is is in Spanish but seemed oddly familiar.

A download and a relatively quick setup of a Windows 2000 VM later, necessary because the installer itself is 16 bits:

Is there some kind of official shorthand for "time until main engine burn"? Kind of like we have "L minus" for launch. An acronym for just the event without explicitly referring to time would be fine too, like an opposite of MECO?

Depends on the spacecraft. The Space Shuttle used "TIG" as "Time of ignition" for maneuvers, that should be generic enough for you, don't you agree?

In Apollo I think they just determined MET for the various burns, given TLAs like TLI, LOI, TEI, etc..

Small nitpicking: Apollo still used GET, not yet MET. About one second difference, otherwise similar

Hmmm, yes, that might work. I just need something short with some flavour as a table column heading (it's got a tooltip, so understanding will hopefully not be a problem). TIG would vibe nicely with the TOF column right next to it... (Time of Flight).

NASA uses the term T_GO for Time to Go, at least during the burns.
