From page 64 of Thomas Wright's text:
Represents a Creation of a double Construction, where a superior Order of Bodies C, may be imagined to be circumscribed by the former one A, as posessing a more eminent Seat, and nearer the supream Presence, and consequently of a more perfect Nature. Lastly,
Represents such a Section, and Segments of the same, as I hope will give you a perfect Idea of what I mean by such a Theory.
Fig. I. is a corresponding Section of the Part at A, in Fig. 2. whose versed Sine is equal to half the Thickness of the starry Vortice AC, or BA. Now I say, by supposing the Thickness of this Shell, I. you may imagine the middle Semi-Chord AD, or AE, to be nearly 6; and consequently thus in a like regular Distribution of the Stars, there must of course be at least three Times as many to be seen in this Direction of the Sine, or Semi-chord AE, itself, than in that of the semi-versed Sine AC, or where near the Direction of the Radius of the Space G. Q.E.D.
Translation from Wallis 1995:
But since segment EA is less than a semicircle,
the centre of the epicycle will
not be in it but in the remainder ABCE. Therefore let K be the centre,
and let DMKL be drawn through both apsides,
and let L be the highest apsis and M
the lowest. Now, by Euclid, III, 36, it is clear that
rect. AD, DE = rect. LD, DM.
Now since LM, the diameter of the circle--to which DM is added in a straight line--is bisected at K, then
rect. LD,DM+sq. KM=sq. DK.
Following his example, let us now proceed to a third trinity of eclipses of the moon, which were painstakingly observed by us. The first was in the year of Our Lord 1511, after October 6th had passed. The moon began to be eclipsed 1 0 1/0 8 equal hours before midnight, and was completely restored 2 0 1/0 3 hours after midnight, and in this way the middle of the eclipse was at 0 7/0 12 hours after midnight--the morning following being the Nones of October, the . There was a total eclipse, while the sun was in of Libra but by regular movement at of Libra.
We observed the second eclipse in the year of Our Lord 1522, in the month of September, after the lapse of five days. The eclipse was total, and began 0 2/0 5 equal hours before midnight, but its midpoint occurred 1 0 1/0 3 hours after midnight, which the day followed--the day before the Ides of September. The sun was in the of Virgo but, according to its regular movement, in of Virgo.
We observed the third in the year of Our Lord 1523, at the close of August It began 2 0 4/0 5 hours after midnight, was a total eclipse, and the midtime was 4 0 5/0 12 hours after the midnight prior to the day before the Kalends of September. The sun was in of Virgo but according to its mean movement at of Virgo.
And here it is also manifest that the distance between the true positions
of the sun and the moon from the first eclipse to the second was , but from the second to the third it was .Now the time
from the first eclipse to the second was
10 equal years 337 days 0 3/0 4 hours
according to apparent time, but by corrected equal time 0 4/0 5 hours. From
the second to the third there were 354 days 3 hours 5 minutes; but
according to equal time 3 hours 9 minutes.
During the first interval the mean movement of the sun and the moon measured as one--not counting the complete circles--amounted to , and the movement of anomaly to , subtracting approximately from the regular movement; in the second interval
C The original text in Canto II, Verse III of James Thomson's The Castle of Indolence reads:
I care not, Fortune, what you me deny:
You cannot rob me of free Nature's Grace;
You cannot shut the Windows of the Sky,
Through which Aurora shews her brightening Face;
You cannot bar my constant Feet to trace
The Woods and Lawns, by living Stream, at Eve:
Let Health my Nerves and finer Fibres brace,
And I their Toys to the great Children leave;
Of Fancy, Reason, Virtue, nought can me bereave.
D Jon Claerbout's dedication remarks:
Most of you know me as the most aggressive proponent of this skylight. If you were slow to make your pledge, you REALLY know me as an aggressive advocate.
I'd like to introduce you to a few other people who also conspired to get us this skylight.
George Thompson -- spotted the architects Dudley Kenworthy -- knew how to make good things happen Julie Hardin -- CAN-DO attitude, transmit ideas to architects.
I asked each of the SEP PhD graduates to contribute. 90The Stanford development office was amazed. Our rate of return is unprecedented.
Not only SEP PhD graduates contributed, but faculty, Biondo Biondi, Jerry Harris, Simon Klemperer, and Lynn Orr and about half of the students living up here contributed. Even our administrative secretaries contributed.
And all your contributions were generous contributions. 17 of you contributed $1000 or more. 35 of you contributed $500 or more. 52 of you contributed $200 or more. Many current students gave a week's pay.
Of course you know the reason why. This place was a dungeon in the sky, and you all knew it. Most of you recall walking down the stairwells, not knowing whether you would emerge into sun or rain, light or dark.
Years ago we ALWAYS went outdoors for lunch, even when it rained. With El Nino this year, we had many January lunches right here where we stand. It was delightful, as you will soon see.
In years gone by, I felt the need to apologize to our new students and visitors for the quality of our quarters. I felt cheated when the Geologists and Petroleum Engineers aced us out of the new Cecil Green building. But no more. Soon you will see that we now have an excellent home.
So I thank you again, for your generous contributions and, on behalf of many future generations, I express to you our heartfelt thanks.
Marie Prucha will recite a poem she has prepared for this occasion. Then we will proceed with the unveiling.
