Happy halloween!

great! :-)

thx, i was not doing that :-)

Is ishimura san on Bluesky? Please encourage him to be here. :-)

clinched just meant (to me) that it came later in the story

geodesy was important, eventually (maybe after it was accepted, whatever)

holding tech bro to these standards seems a high bar that they possibly could not attain (but i missed the entire interaction) :-)

i am not and have never argued that what your tech bro wrote was accurate in any way
if you treat him like a non geologist undergrad, he was pretty good

and especially never suggested that geodesy put nail in the pin for plate tectonics

not sure why you are singling this out: time of acceptance

"What clinched it was Satellite Laser Ranging, a product of the space race."

this states that langbein's work was not in the beginning, but later

a friend steve bacon talked about helping out in the late 90s, early 2000s on the east side of the sierra. this work preceded gps

well, as your post mentioned, this tech guy got it right. langbein's work was later (not in the development). his geodetic work was revolutionary using lasers of different wavelength to make geodetic measurements in, e.g., long valley caldera/eastern sierra.

i am sure you told them that in large part, the laser and related measurement technologies that John Langbein used in his early geodetic work were indeed products or offshoots of technologies developed during the space race era

unless he got that from you already (probably)

gotcha

i am only seeing a part of the conversation

looks like they are reading the answers from their neighbor :-(

it seemed like they were simply getting the details wrong. plagiarism is the one thing that i was VERY serious about in classes i taught

i appreciate your feedback. thanks

this is what keeps me going (seriously)

yes, the house is finished. now working on transforming my outbuilding to livable space so i can rent it out and build a new house on some land i just purchased in the redwood forest. photos pending :-)

John Langbein's work was revolutionary

to his credit, he did not state this was the advent of plate tectonics, but much later in the process. he nailed it

if this fellow were in an intro class, he would have gotten an A+

magnetic anomalies mapped by magnetometers in post-WW2 vessels was a key part of this. so, pretty close. like, spot on perfect.
