A week of lunar observing to mark the International Year of Astronomy’s Spring Moonwatch.
The Royal Observatory’s 28-inch refracting telescope, the largest of its kind in the UK, will be open in the late afternoons (weather permitting).
Visitors can view the moon’s mountains and craters in detail, with expert guidance from one of our astronomers. Opening times vary from day to day with the rising and setting of the moon.

Mise en Abyme is, originally, a figure in heraldry in which the figure in the centre of the shield, [the abyss of the escutcheon] reproduces the whole shield, and in the centre of that is yet another smaller representation of the whole and so on. So we have an infinite repetition with infinite regress.

In I Am a Strange Loop, Hofstadter defines strange loops as follows:
|“||And yet when I say "strange loop", I have something else in mind — a less concrete, more elusive notion. What I mean by "strange loop" is — here goes a first stab, anyway — not a physical circuit but an abstract loop in which, in the series of stages that constitute the cycling-around, there is a shift from one level of abstraction (or structure) to another, which feels like an upwards movement in a hierarchy, and yet somehow the successive "upward" shifts turn out to give rise to a closed cycle. That is, despite one's sense of departing ever further from one's origin, one winds up, to one's shock, exactly where one had started out. In short, a strange loop is a paradoxical level-crossing feedback loop. (pp. 101-102)|
March 31st, a great fit of the stone in my left kydney: all day I could do but three or four drops of water, but I drunk a draught of white wyne and salet oyle, and after that, crabs’ eys in powder with the bone in the carp’s head, and abowt four of the clok I did eat tosted cake buttered, and with suger and nutmeg on it, and drunk two great draughts of ale with it; and I voyded within an howr much water, 49 and a stone as big as an Alexander seed. God be thanked! Five shillings to Robert Webb, part of his wagis.

- 'In colouring the Crompton is warm and bright: a black suit decked with gold chains worn sashwise, a gorgeous blue-tinted ruff and a scarlet flower in his hand. The Background is a plain buff-coloured light brown, the inscription is in yellow, and he has not hesitated to use gold leaf in the delineation of the arms, although he has not used it for the jewels.'

Perennial; pink, white, yellow or blue, as well as the wild red-and-yellow va; riety. Blooming in May and June, and about two feet in height. The aquilegia should be provided with a rich, moist soil, and will grow in either sun or partial shade. It is self-sowing to some extent, although the seedlings do not come true. It is quite hardy, and requires little care.
blue columbine has been associated with melancholy ever since the fifteenth century

...Before there can be any interpretation of dreams, three secular fallacies need to be dismissed. The first is the philosophers' prejudice, which holds that dreams are without objective, reasonable connection and are unworthy of interpretation. As opposed to Hegel [whom, justifiably, he cites only indirectly], Freud prefers to follow the lay opinion, that assumes "a meaning, though a hidden one" in the dream. But popular dream interpretation has remained translation in two complementary ways: it makes the whole dream "symbolic" of global meanings, or it translates parts of a dream by "mechanically transferring" each part "into another sign having a known meaning, in accordance with a fixed key." Both techniques, the analogical and the digital, presuppose that the two media, the dream and language, are either similar or co-extensive. The new science rejects these two views as naive...

like if you connected your dmm probes to a piece of wire then cut the wire - the circuit is 'open' and
the electricity can't flow.
Opposite of open circuit is short circuit
- if the component you are testing has its terminals connected with a wire, the electricity flows down the short path i.e. path of least resistance. the energy would bypass the component so it wouldn't work and the energy flows in the short circuit instead.
...Bataille left his mark everywhere between real, infra-real and supra-real. His way was Nietzsche's - eruptive and disruptive. He accentuates divisions and widens gulfs rather than filling them, until that moment when the lightning flash of intuition/intention leaps from one side to the other, from earth to sun, from night to day... Lefevbre The Production of Space
Zizek also uses the notion of the short circuit in discussion of the 'parallax gap' - points between which no synthesis or mediation is possible.
The faulty connection, cross wiring, is like Freud's Fehleistung... misperformance, faulty action...parapraxis.

Hyperbolas may be seen in many sundials. On any given day, the sun revolves in a circle on the celestial sphere, and its rays striking the a point on a sundial traces out a cone of light. The intersection of this cone with the horizontal plane of the ground forms a conic section, by definition. At most populated latitudes and at most times of the year, this conic section is a hyperbola. In practical terms, the shadow of the tip of a pole traces out a hyperbola on the ground over the course of a day. The shape of this hyperbola varies with the geographical latitude and with the time of the year, since those factors affect the cone of the sun's rays relative to the horizon. The collection of such hyperbolas for a whole year at a given location was called a pelekinon by the Greeks, since it resembles a double-bladed ax.
