Retirement = knee surgery on Day 1 = misery for the past year when it didn't heal right = depression for lost dreams = despair = ...wait a minute... one day the sun will blow up and burn everything up anyway = I don't give a rip = forced optimism by deduction.  Not really, but one can only sink so low before bouncing back, I guess.  Actually, I'm a Realist = take my telescope out at night, take the dog to the woods in the daytime, play my guitar, and try not to worry.  Besides, if the sun goes soon I can watch it in the scope (with a filter, of course).  Best cure for da blues is to do something, anything.  If you do nothing, nothing gets done.  When something gets done I feel better.

It's normal for replies in a thread to be chronological, but not normal to see threads listed in the way you describe. Does this mean you are seeing threads from several years ago listed on page 1?

Asreroids are coming.  If they don't smack us hard enough they could still bring deadly microbes.  Or Yellowstone may pop before then.  Or we'll do ourselves in in our own way.  Global warming may release too much methane from the ocean floor. don't matter anyway if we're still here when the sun becomes a red giant.  We better get on the stick about such stuff.  Dear me,  makes me depressed.  Better go eat me some chocolate.

Here ya go, I'm new here, so we're up to date.  I only wish my pages showed the most recent replies at the top of the list instead of the bottom or on the last page.  And that threads replied to be bumped to the top of thread listings.  That doable?

Seems it did.  Logged in this morn ok.

Just tried it again, and all is well.  Thanks for your help.

I see.  The problem still interests me, but I wouldn't want to revive any past tremors.

Thanks for the welcome.

Doggonnit, I'm sorry, I should've said hexagon.  A hexagram contains the lines that connect the points of a hexagon through its center.  Correct me if I'm wrong.  I should follow what Davy Crocett said, "Make sure you 're right, then go ahead."

So, we can get "hexagon shaped" cookies and biscuits by the process I described above. (Of course, then you could cut them into pieces according to the lines of a hexagram).  Now I think I'm getting hungry.

Uh...I see, after a little searching that the topic has caused a bit of a me divert upon another path to begin my happy journey here.  Had no idea.

Thanks.  Very curious problem that was.

Ok, shall I print what I'd like it to be right here or somewhere else that is safer?

That is way cool.  What gets me is if you put the sun beside some of the other stars out there it would be like grain of sand beside a basketball, or even smaller in some cases.

Circles of equal diameters, when pressed together form hexagrams.  See the proof when baking cookies or biscuits by placing the dough so that their edges barely touch.  After baking, the ones in the middle will have six straight sides.

Just found this site.  Looks interesting, so I signed up.  Typing on my phone so it's slow going with these tiny buttons.  I'm a retired guy, 66 years "young"who always enjoyed math, especially the wonders of geometry.  Not very good at much, but I still like to ponder things.  Retired from the South Carolina State Museum after 30 years last year.  I am also a musician and active amateur astronomer.

I ran across the topic of "Does 0.999... = 1?" online (which is how I discovered this site).  I'd like to know where I can read some discussion about that on here.  Anyone know where to find it? 

Anyway,  cheers to all.  Glad to be here.
