Re: The Mysterious Voynich Manuscript (2010 Jan 31)
The first question that comes to my mind is what is the function of the Voynich manuscript. Or as Louis Sullivan coined the phrase "Form ever follows function." It is the pervading law of all things organic and inorganic, Of all things physical and metaphysical, Of all things human and all...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
I've stated the case for what I see as a likely cause of the triple sunrises. My position has been attacked by browbeating point-by-point refutation arguments based on attacking my perceived stupidity. I've said my peace and rest.

Re: Cause of Triple Sunrise (APOD 2009 August 4)
Res ipse loquitur . Stratocumulus clouds over land, open expanse of sky above water. Sunrise, water warmer than the land, convection currents carry warm moist air aloft and it descends over the land condensing into clouds. The foreground stratocumulus clouds' edges' crispness indicates light horizo...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
Vertical-convection-current collimated and axially oriented condensation products in the stratocumulus clouds act collectively in high magnitude exponential numbers as prisms. The Sun's light is radially polarized by the millions of kilometers of intervening distance in the vacuum of space, effectiv...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
I suppose then that binoculars are based on pseudoscience, that six prisms arranged in tandem with a pinpoint polarized light source directed into them projecting an ordinary image and two extraordinary mirages on a viewing plane are pseudoscientific play. That there's only pseudoscientific evidence...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
There's a hundred kilometers of waterway between the Gdansk bay shores below the solar images. My examination indicates to me that the ordinary solar image has a vase neck and a vase foot. The first extraordinary mirage has a foot but no neck. No apparent foot or neck on the second extraordinary mir...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
Attacking me doesn't disprove my viewpoint. The logical fallacy of an ad hominem attack is it shifts discussion off topic and ignores the assertion under debate by attempting to discredit the messenger, and by faint implication discredit the messenger's assertion.

Re: Cause of Triple Sunrise (APOD 2009 August 4)
My fifth grade teacher sent me to sit on a stool in the classroom corner and wear a conical cap for asking in geography class if the continents moved. I spent a class-week there ignoring the ridicule of the teacher and the classroom bullies before the teacher relented. In eighth grade geography, the...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
An absentminded slip of the mind. A false dawn is an atmospheric dispersion effect, unfocused refraction. A false sunrise is a focused double-refraction effect. Poro prism binoculars demonstrate changing the path of a light beam, they correct and erect the image to true orientation and extend the le...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
I don't see how they're not. One refraction to decompose the beam and one to return another decomposition refraction along the direction of the original beam's travel. Rainbows and raindogs certainly are single refractions.

Re: Cause of Triple Sunrise (APOD 2009 August 4)
The mirror reflection simulations themselves demonstrate the beam splitting principles of birefringence, probably caused by resin coatings and birefringent chemicals added to the glass formulation to control glare, UV light, and themal properties. Other atmospheric mirage phenemonas of bifringence, ...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
I ran the subject image through routines I use for detecting digital retouching. I found expected compression artifacts but no evidence of localized alterations. I did find retouching evidence (and compression artifacts) in the admitted retouched simulation images contained in this thread. The metho...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
The foreground clouds appear to be stratocumulus lenticularis or undulatus. The clouds on the horizon in front of the sun appear to be the same. The open expanse of sky in between is over Gdansk Bay. At sunrise, large bodies of water are warmer than adjacent land. The slight difference in air temper...

Re: Cause of Triple Sunrise (APOD 2009 August 4)
Refringence, in this case trirefringence, might explain the triple images. The causes of this particular image phenomena might include curvature of and the distance sunlight traveled through Earth's atmosphere, atmospheric conditions, relative position of observer. Refringence is the decomposition o...
