Braid Quotes (2 quotes)
Locksley Hall, that in the distance overlooks the sandy tracts.
And the hollow ocean-ridges roaring into cataracts.
Many a night from yonder ivied casement, ere I went to rest,
Did I look on great Orion sloping slowly to the west.
Many a night I saw the Pleiads, rising thro’ the mellow shade.
Glitter like a swarm of fireflies tangled in a silver braid.
And the hollow ocean-ridges roaring into cataracts.
Many a night from yonder ivied casement, ere I went to rest,
Did I look on great Orion sloping slowly to the west.
Many a night I saw the Pleiads, rising thro’ the mellow shade.
Glitter like a swarm of fireflies tangled in a silver braid.
From 'Locksley Hall' (1842), collected in Alfred Tennyson and William James Rolfe (ed.) The Poetic and Dramatic Works of Alfred, Lord Tennyson (1898), 90.
One evening at a Joint Summer Research Congerence in the early 1990’s Nicholai Reshetikhin and I [David Yetter] button-holed Flato, and explained at length Shum’s coherence theorem and the role of categories in “quantum knot invariants”. Flato was persistently dismissive of categories as a “mere language”. I retired for the evening, leaving Reshetikhin and Flato to the discussion. At the next morning’s session, Flato tapped me on the shoulder, and, giving a thumbs-up sign, whispered, “Hey! Viva les categories! These new ones, the braided monoidal ones.”
In David N. Yetter, Functorial Knot Theory: Categories of Tangles, Coherence, Categorical Deformations, and Topological Invariants (2001), 8. Yetter writes this personal anecdote is given as a narrative in his own words. Presumable the phrases in quotation marks are based on recollection when written years later.
In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.
(1987) --
