<umbralraptop> !8 is a gigawatt lightsource at 1200 km a good idea?
<galois> umbralraptop: no
<umbralraptop> (It's fine. There's probably an error in my calcs upping the power by a factor of 1000)

* umbralraptop hears someone give a non-japanese pronounciation to hypersuprime cam
<egg|laptop|egg> umbralraptop: is hypersuprime a number theory thing
<umbralraptop> egg|laptop|egg: if you make it a thing?
<egg|laptop|egg> hyperperfect and superperfect are a thing
* umbralraptop pokes the hyperperfect and superperfect numbers with a conifer
<galois> Sorry, I can't make sense of that URL.

<umbralraptop> TIL that AmTrak runs 0 trains to the 2nd largest city in the country
<umbralraptop> If *San Fransisco* is too small to merit train service...
<umbralraptop> huh, apparently LA is larger
<umbralraptop> though wikiality seems to be using an estimate that is not an MSA
<WeylandsWings> umbralraptop: i mean the US train system is a travesty IG
<umbralraptop> something something fun with abstracts? https://arxiv.org/abs/2010.08557
<galois> title: [2010.08557] Can the EHT M87 results be used to test general relativity?
<umbralraptop> WeylandsWings: yeah, and it's fractally bad. see eg: the line from KC through Hutchinson that somehow misses Wichita
<WeylandsWings> or how the network is a whole bunch of generally disconnected services
<WeylandsWings> plus not owning their own tracks and having to give way to freight
<umbralraptop> yeah, coal being more valuable than passengers is, uh, an interesting set of priorities
<WeylandsWings> I have had the thought of what if you just use the medians of the major interstates as the rail baseline
<umbralraptop> That would be a good start on how many lines you'd need
<WeylandsWings> because you have good access, already have the easements
<WeylandsWings> the issue is the bend radii
<umbralraptop> Though I'm pretty sure that the ~900 km between KC and Denver causes numeric overflows for any HSR advocate outside of China
<WeylandsWings> esp as we should be looking at HSR
<WeylandsWings> but that isnt unsurmountable
<WeylandsWings> bundle the rail building with a massive reworking of the Interstate system (new bridges, repaving, realigning) and you can kill 2 birds with one stone
<WeylandsWings> really 3 birds as you will probably kill 2-3 of the US airlines
<umbralraptop> Yeah, also need to build out intracity transit so the rail stations are usable
<WeylandsWings> one thing at a time
<WeylandsWings> just remember all the NIMBYers who worry that public transit will bring [undesireable demographic] into their neighborhoods
<umbralraptop> [extremely monotone voice] oh, no. not the property values

<whitequark> egg|laptop|egg: flir one
<egg|laptop|egg> what band does it look at?
<egg|laptop|egg> ah 8-15 µm apparently
<umbralraptop> IRAC channels 3 and 4?
<umbralraptop> huh, Spitzer was bluer than I thought. Just channel 4 ish
