David Koot Posted February 9, 2008 Share Posted February 9, 2008 And in response to Planey's question, as I understand it the mirror actually *doesn't* left-right invert things either - it's an illusion. What it actually does is keep things in the same direction - i.e. keeps the right side of our face on the right side and the left side on the left. A flat-surface mirror does indeed reverse the direction perpendicular to the plane of the mirror. The phenomenon is referred to as 'lateral inversion.' In order to see the non-inverted reflection, one would need to look at the image traveling AWAY from the mirror--which would be quite impossible. Once again, draw a diagram of light waves striking the mirror's surface, and you can see how it occurs. A parabolic or spherical mirror inverts the image at the focal point. Again, in order to see the non-inverted image, an observer would need to view the light cone from the point of reference of the focal point, looking out--which, again, would be quite impractical.

David Koot Posted February 9, 2008 Share Posted February 9, 2008 But this IS the WIDE subject! In its most recent convolution, Bravus was headed off to the pool. Haven't heard from him yet.

D. Allan Posted February 9, 2008 Share Posted February 9, 2008 Quote: The *true* field of view remains constant, and is not affected by distance,... i'm not convinced! Standing close to the mirror, the furniture to the side of and behind me can be seen in the mirror. Standing far from the mirror, said furniture is now in front of me and no longer shows up in the mirror. Quote dAb O frabjous day! Callooh! Callay!

D. Allan Posted February 9, 2008 Share Posted February 9, 2008 It's Russian, JeanMarie. (I love to say 'Jean Marie' in french. btw parlez-vous le francais?) I'm just beginning to study the Russian alphabet. The quote is from Mark 4:14 "The farmer sows the word." niv In Russian there is no "the." слово (slovo) = word. i like words thanks for asking, JeanMarie Quote dAb O frabjous day! Callooh! Callay!

Guest JeanMarie Posted February 9, 2008 Share Posted February 9, 2008 :) Thanks dAb! No, I don't really speak any language but English, but can understand quite a bit of French, German, Spanish, and Yiddish, and bits of Italian. Quote Link to comment Share on other sites More sharing options...
D. Allan Posted February 10, 2008 Share Posted February 10, 2008 That is quite a list, JeanMare! I'm curious - what is your favorite? Quote dAb O frabjous day! Callooh! Callay! Link to comment Share on other sites More sharing options...
Guest JeanMarie Posted February 10, 2008 Share Posted February 10, 2008 I enjoy listening to French, as long as I don't have to come up with a reply. And I also like to hear English spoken in other countries aside from the USA, i.e. Australia, Great Britain, Tennessee, Kentucky, Georgia... :) Quote Link to comment Share on other sites More sharing options...
D. Allan Posted February 10, 2008 Share Posted February 10, 2008 Oh yes the many flavors of English give it a nice variety. French is my favorite. I'm not proficient in it, however. Quote dAb O frabjous day! Callooh! Callay! Link to comment Share on other sites More sharing options...
Planey Posted February 10, 2008 Share Posted February 10, 2008 ...I also like to hear English spoken in other countries aside from the USA, i.e. Australia, Great Britain, Tennessee, Kentucky, Georgia... You're right about the first two mentioned - however I'm not sure that the language spoken in the latter three actually qualifies as English!

David Koot Posted February 10, 2008 Share Posted February 10, 2008 I'm not sure that the language spoken in the latter three actually qualifies as English! Graeme It varies. Certainly in eastern Tennessee, in rural areas, the English that is spoken is still not that far removed from that of the Restoration. Kentucky, once again, has pockets of tradition which would be largely recognizable to an Englishman of the 1700's. Georgia, on the other hand, is indeed different. Georgia was a slave state, with a large African population. The 'English' spoken there is an admixture of English and African-American. A rather unique language.

D. Allan Posted February 10, 2008 Share Posted February 10, 2008 The English i've heard in Georgia has a warm accent. I love it. Also the southern African-American accent sounds much better to me than some British and Austrailian versions of our language. But for me it all depends so much more on the elocution of the speaker than on the dialect. Quote dAb O frabjous day! Callooh! Callay! Link to comment Share on other sites More sharing options...
David Koot Posted February 10, 2008 Share Posted February 10, 2008 What I find puzzling, Monsieur, is the fact that even though so much of the language and culture (for example, the music) of the Deep South reflects African-American influence, there has been such strong and pervasive prejudice against African-Americans. To this day, it still exists in some areas. Quote Link to comment Share on other sites More sharing options...
