overall source is
M. Kolomiets, “Bitva za Moskvu”, Frontovaya Illyustratsiya/Frontline Illustration, No 1, 2002
i have not found any western source that confirms this, neither any other source dating before 2002. it would be good if someone checked sources in that book cause i am still not convinced that t50 was in moscow.
not infallible. think that last big fail of peer review was serotonin research on depression. everyone quoted original research that was made in 50s or 60s, countless books were written and when you tracked sources in most books they would all point to that 1 research. it was taken as an established fact in psychiatry, just to be proven wrong after 60-70 years.
most book sources arent wrong. but there exists bad habit in scientific community of crossreferencing books/researches that all point to one source and/or that source isnt checked for correctness of information. doesnt matter if it is book or research.
Our comprehensive review of the major strands of research on serotonin shows there is no convincing evidence that depression is associated with, or caused by, lower serotonin concentrations or activity. Most studies found no evidence of reduced serotonin activity in people with depression compared to people without, and methods to reduce serotonin availability using tryptophan depletion do not consistently lower mood in volunteers.
imagine prescribing wrong medicine for ~60-70 years based on faulty research/theory.
