Talk:Friedrich Zander

message: Why is Tsander's name transformed into a German spelling?  It's particularly incorrect to change the spelling of his middle name, which is a Russian-style patronymic.  And if his grandfather was named Konstantin, it is not clear he was even purely ethnic German.  Do we even know if his family spoke German or spelled their name in that fashion?
This was inappropriate and non traditional.  The German and Latvian spellings could be mentioned at the beginning, but it is very peculiar to spell his name "Zander". DonPMitchell 02:56, 13 February 2006 (UTC)
replies: text: I've softened my opinion about this issue, finding that Zander kept his personal notes in German. I still believe he clearly embraced the Soviet Union as his home, so I think it is also fair for Russians to call him a "Soviet".  And Latvia can have their rocket pioneer too.  Racial origin, national origin, and citizenship all being different, it is an abiguous situation. DonPMitchell (talk) 17:45, 20 June 2008 (UTC)
thread_title:  Germanizing names 

message: I did a pretty extensive rewrite of this article, adding information and fixing some mistakes (GIRD-10 was not the tenth try at a rocket, for example, it was one of 10 projects underway in four different brigades).  The Russian wiki page had a better structure and more information, but I also pulled new information out of some aticles in the AAS History series and in Asif Siddiqi's paper "Deep Impact" which discusses the 1920 'space fad' in Russia.

thread_title:  Big Update 

message: I'm not sure Tsander talked about a light sail.  He definately talked about focusing solar heat to increase the exhaust velocity of a rocket.  The use of solar energy in space was also discussed by Goddard around 1916.
Perelmann definitely discusses the idea of using light pressure as propulsion in space, in his 1915 book "Interplanetary Journey". DonPMitchell (talk) 02:54, 18 July 2008 (UTC)
replies: text: nevermind, just found his discussion.  He proposed a 100,000 m**2 by 1/1000 mm thick foil sail to use light pressure.  This is in one of his early "Overflight to the planets" lectures. DonPMitchell (talk) 18:22, 19 July 2008 (UTC)
thread_title:  Light Sail? 

message: Was Kondratyuk involved in the Society for Interplanetary Travel?  I do not believe so, he contacted Vetchinkin in 1925, and I don't think he was known to the Moscow rocketry people before that. DonPMitchell (talk) 16:43, 4 July 2009 (UTC)
thread_title:  Corrections 

message: I would strongly suggest to remove that reference to that fishy diploma.

replies: text: Russian spelling was quite different in pre-revolutionary time, particularly in more extensive use of the hard sign.  I'd hesitate to act on this person's suggestion, particularly since he is anonymous and offers no other evidence that Tsander's diploma is fake. DonPMitchell (talk) 06:22, 17 December 2015 (UTC)

text: Well I see he removed it.  I'm not going to bother to restore it, but I don't believe this person knew what he was talking about.  Particularly since he didn't seem to recognize pre-revolutionary spelling. DonPMitchell (talk) 06:28, 17 December 2015 (UTC)
