Lunar Eclipse Video

This was taken from a time lapse video in Hawaii, on August 28th, 2007, not the recent one, I know, but the quality is high.

Apparently, the color of the eclipse is measured on the Danjon scale, and the February 20, 2008 eclipse was considered brick red, or L=3.  The light that does reach the moon is refracted through our atmosphere, the shorter wavelengths more likely to be deflected by small particles, the longer ones getting through, thus the moon appears red as the light bounces back to your eyes from its surface.

Or so I’ve found out. 

Addition:  February 20th eclipse here.

Lunar Eclipse And A Wednesday Poem: Matthew Arnold

Tonight, the lunar eclipse happened between 7:01 PST and 7:51 PST here in Seattle, and fortunately for us, it was a clear night.  In the penumbra of the earth’s shadow, there was just some darkening, but then the moon appeared inky black in direct shadow, and an overall reddish color for a few hours.

Here’s a NASA page, which includes some great photos.

For some reason I was reminded of a Matthew Arnold poem (which barely mentions the moon, and now that I look it, mentions a love, which is creepy in this context) as I stood in wonder and talked with a Muslim friend, who kept suggesting that such events were foreseen in the Koran.  Honestly, I was thinking of gravity, and the simplicity and depth of those laws.   It’s a strange life, sometimes.

Dover Beach

The sea is calm to-night.
The tide is full, the moon lies fair
Upon the straits; on the French coast the light
Gleams and is gone; the cliffs of England stand;
Glimmering and vast, out in the tranquil bay.
Come to the window, sweet is the night-air!
Only, from the long line of spray
Where the sea meets the moon-blanched land,
Listen! you hear the grating roar
Of pebbles which the waves draw back, and fling,
At their return, up the high strand,
Begin, and cease, and then again begin,
With tremulous cadence slow, and bring
The eternal note of sadness in.

Sophocles long ago
Heard it on the Agaean, and it brought
Into his mind the turbid ebb and flow
Of human misery; we
Find also in the sound a thought,
Hearing it by this distant northern sea.

The Sea of Faith
Was once, too, at the full, and round earth’s shore
Lay like the folds of a bright girdle furled.
But now I only hear
Its melancholy, long, withdrawing roar,
Retreating, to the breath
Of the night-wind, down the vast edges drear
And naked shingles of the world.

Ah, love, let us be true
To one another! for the world, which seems
To lie before us like a land of dreams,
So various, so beautiful, so new,
Hath really neither joy, nor love, nor light,
Nor certitude, nor peace, nor help for pain;
And we are here as on a darkling plain
Swept with confused alarms of struggle and flight,
Where ignorant armies clash by night
.

Matthew Arnold

Goethe’s Color Theory: Artists And Thinkers

Johann Wolfgang Von Goethe is perhaps Germany’s greatest poet and writer, best known for Faust.  Not so well known is Goethe’s theory of color (which claimed insights that could refute Newton).  Like many artists, Goethe isolated the effect color has in terms of experience, making profound observations on refraction…for example…but for which he didn’t have a workable theoretical framework.  To this, a certain type of philosopher might say:  he ignored the fact that his thoughts and his senses combine to form experience.

Goethe from Steiner, from wikipedia:

The colours therefore, to begin with, make their appearance purely and simply as phenomena at the border between light and dark…”

Colours arise at the borders, where light and dark flow together.”

Click here for a visual representation.

Goethe seems to have thought of light and dark in terms of a metaphysical dualism, from whose interaction color is born.

Newton held that white light passing through a prism is diffused into its various wavelengths.  He also may have steered the discussion into wave-particle duality.

Don’t Drink The Water: Pond Water Under A Microscope

Here are some quotes from Six Easy Pieces, by Richard Feynman:

If we look at it very closely, we see nothing but water-smooth continuous water.”

At 2000x:

“…the water drop will be roughly forty feet across, about as big as a large room, and if we looked rather closely, we would still see relatively smooth water-but here and there small football-shaped things swimming back and forth.  Very interesting.”

At 2000x times more:

Now the drop of water extends fifteen miles across, and if we look very closely we see a kind of teeming something which no longer has a smooth appearance-it looks something like a crowd at a football game seen from a very great distance.”

Biology gives way to physics.

Mike Oldfield’s To France: By A Spanish Pianist…and Plato?

Mike Oldfield wrote tubular bells, the eerie background music for the Exorcist.  He also wrote To France, a tribute to Mary Queen of Scots escape from England which is covered in the video above.  The song catches some of the spirit of English ballad and traditional folk while dealing with Protestant/Catholic subject matter.

Spaniards have a real interest in Oldfield, and I can’t help but wonder if there aren’t some shared Catholic traditions that spark the Spanish interest in Oldfield’s music (besides all the shared history).

………. 

On a related note, an emailer wrote me wondering why I had posts about music, when many other posts contain arguments which are contradicted by an indulgence in music.  I’d say there certainly is a lot of naivete and danger in seeking transcendance through music, which is so easily used by politicans, armies on the march, churches, dictators, …even witch doctors… to soften the mind rather than sharpen it, to incite the passions, and even perhaps to corrupt the spirit.

It’s not anything you won’t find in Plato, or in this essay on Plato, frankly:

This also meant that the artist is two steps removed from knowledge, and, indeed, Plato’s frequent criticism of the artists is that they lack genuine knowledge of what they are doing. Artistic creation, Plato observed, seems to be rooted in a kind of inspired madness.

So, good point, dear emailer.

Ron Csillag In The Toronto Star: Math + Religion=Trouble

Csillag has an interesting article on the combination of mathematics and mysticism, in which he seems motivated by a fear that deep impulses and beliefs channeled into the metaphysical doctrines and practices of religion, or at least left unexamined by the believer…are dangerous, especially if the believer happens to be a great mathematician.

Betrand Russell also accused the Pythagorean cult of combining the two, perhaps in an unnecessary way.  Would Csillag agree with with Russell’s atheism and empiricism?

Here’s the final line of the piece:

Or as Paulos might say, no mathematician has ever deliberately flown planes into buildings

But some mathematicians have discovered equations that were eventually applied to the creation of the atomic bomb.   Is mathematics a set of pure ideas unrelated to the moral consequences that flow from them?

I’m not convinced Csillag’s argument has to do particularly with religion, nor Islam, rather than (as a piece of journalism) with the construction of an edifice of atheism, or maybe an attack on that edifice.

Does it all lead back free will?
