25 Oct 06 - 09:10 PM (#1868741) Subject: RE: BS: Astronomy Question From: Bunnahabhain It depends on when in the year you are. Ignoring precessional issues, which will not be vastly relevant over one year... It will be twice the number of days until the next solstice (either one) before the sun rises in the same position again. If it's a solstice, it's a year. Example. It's a week before the solstice. The sun will rise in the same spot in 15 days ( week x 2 plus the solstice) This is assuming the boulder isn't on a glacier moving down the valley, or anything else |

25 Oct 06 - 11:42 PM (#1868823) Subject: RE: BS: Astronomy Question From: JohnInKansas Within the accuracy of Zogg's measurement capability, the same configuration of sunrise at the same azimuth/elevation will appear on the same date in one year. Since the actual "calendar year" is 365.24 days (approximately) the time of day at which the precise "solstice moment" appears changes slightly, hence there is a slight lateral drift of the solar path apparent from his observation point. For a "more nearly exact" alignment he'll have to wait four years for the "leap year adjustment" to resynchronise. For an "almost exact" alignment he'll have to wait 100 years for realignment with the leap year that's dropped out in even centuries. For truly precise observations, he should refer to "sidereal time" rather than calendar or clock time, and probably should synchronise his observations with the atomic clocks and the international timekeepers, to keep track of the "leap second" corrections that accomodate wobble and drift in the earth's motions.

If there were two 1/2 inch X 1/2 inch steel bars that were each a mile long 2. and those bars were end to end with an inch gap between the ends 3. and say that the expansion of steel would be > 1 inch per mile if heated to 500 degrees 4. and those bars were free to move in any direction as they expanded with the heat ...does anyone doubt that when heated to 500 degrees they would close the 1 inch gap and touch? Now imagine... 1. those same steel bars with that same expansion rate 2. all as a small part of a steel washer (not something that washes steel, rather, a coin shape with a hole in the middle) that is two miles in diameter, 1/2 inch thick, with a one inch hole in the middle. 3. and imagine that those two bars in the above scenario are actually still end to end, but they have yet to be cut out of that washer -- they are still end to end -- and the inch gap in the above scenario is now the one inch hole in the middle of the washer. 4. heating the washer up to 500 degrees now... ...does anyone think that the hole in the middle of the washer will close? |

07 Jan 07 - 03:41 PM (#1929436) Subject: RE: BS: Astronomy Question From: John Hardly Hey, Thanks for the answer, John. Really. It's kinda light-hearted musing on my part. The question came up about the notion of a steel donut being heated and whether the hole would get bigger or smaller. I immediately thought bigger. I thought about the idea of heating a stubborn nut off of a bolt. I thought of running warm water over a stubborn lid. But when asked why the expansion of the steel wouldn't expand into the hole, all I could come up with was a bit of conjecture on my part... ...that it is the bond, not the atom that causes expansion. Thus, if the atoms that make up the innermost ring of atoms (the one that would define the perimeter of the center hole), the atoms are not going to change, but they will exhibit the same force of expansion in the bonds between them. In fact, if there were only one ring of atoms, I doubt that anyone would even wonder if the ring would get bigger. It would seem more obvious. And the atoms can't "leapfrog" one another. We're not talking about melting the steel. We've all seen sugar cookies close up holes as they expand in the heat of the oven. I further figured that, at the very least, there would be a "keystone-ing" effect -- in other words, the center ring of atoms, rather than getting compressed by the action of the outer atoms "trying" to expand in all directions, would instead, be more inclined to direct all expansion outward. The "keystone-ing" by those atoms would, in effect, be the same as if the two bars in the first scenario met in the middle and thus started pushing all expansion toward the opposite ends. I'm sure there's a simpler explanation. That was just what my sense of things came up with. Sadly, Zogg drop things on foot all time. And to frustrate Zogg even more, bad words not invented yet. |

08 Jan 07 - 04:10 AM (#1929963) Subject: RE: BS: Astronomy Question From: Slag With regards to the original question: Zogg's rock formation resembles a T-Rex which raises some very red flags concerning evolutionary sequence but for argument's sake I'll go with it. To be recognizable as a large carnivorous sauropod, Zogg's scale would have to be around 1 degree. The Sun consistantly appears 1/2 degree as seen from Earth. This makes for quite a bit of slop in his observation so while the Sun may only PRECISELY "rise" in the same spot every 365.256 days it would appear to Zogg to rise in the same spot twice a year. The closer to the solstice positions the sooner this would occur. If the alignment were at the equinox postions then the occurence would be one half year apart (182.63 days). |
