The wide subject

Recommended Posts

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.

But this IS the WIDE subject! In its most recent convolution, Bravus was headed off to the pool. Haven't heard from him yet. Hope the bloke is okay! Perhaps he is still working on his diagrams.

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.

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 :)

:) 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.

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... :)

Oh yes the many flavors of English give it a nice variety.

French is my favorite. I'm not proficient in it, however.

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!

ROFL When did Tennessee, Kentucky and Georgia become other countries? I must have missed the breaking news.

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.

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.

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.

Far, far more than just some.

Children are not born prejudiced so they must learn it from their families and friends, and other cultural influences as they live. We 'white people' owe much gratitude to Martin L. King and those who marched with him. He helped set us free, too!
