"The model suggests that a clock in the Milky Way would be about 35 per cent slower than the same one at an average position in large cosmic voids, meaning billions more years would have passed in voids."
If the gases pulled in toward a black hole were experiencing only tens-of-millions-of-years of time during a full billion years (as compared with the billion that elapsed on a clock experiencing a lower-gravity "universal average" condition of gravitation and of time), then does that mean...
that those magnetic fields and gases must emit to us any greater or smaller intensity of radiation vs. the amount that they would emit if they had been rubbing together within our own rate of time?

When faced with prospects of two different kinds of boring, Goldsberry points out that the NBA could either make its courts several feet wider to at least diminish the statistical make-percentage advantage of those 3's -- but that this would mess up arena seating arrangements -- or could outright allow teams to draw their own 3-point lines like the local variation in baseball and soccer [2] fields.
Basketball requires control of space and pace, but as athleticism has increasingly been optimized, there's just not enough space there to force interesting trade-offs on every play. So it forces less interesting ones.

The garden suburb "first emerged in England in the 1830s" per David Fishman [NB: not the same scholar as Robert Fishman] Bob Stern, and Michael Tilove's book "Paradise Planned," but garden suburbs are just one of the forms that subsequent waves of suburbanization have taken; earlier waves were also going on, and have continued to as well.
The Georgian (1710s-1820s) squares of many cities in England, for example, didn't have estate-style lawns nor walls around the neighborhoods, but they often had locked fences all around the garden. These private parks were known as squares, yes, but had little in common with cobblestoned market squares; the houses were sometimes even low-rise fashionable villas (among them Lloyd Square -- near the Angel of Islington -- a development which is still intact in Inner London). The fancy Clifton area of Bristol is at a higher elevation than the old port city but I disagree that separation from the core or social desirability are really what define a neighborhood as being suburban. Lloyd Square is a little unnervingly low; its buildings struggle to effectively amplify the space or create "positive space" because architecturally they can't anchor or confine it. So one perspective on suburban environments is this: they all exhibit urbanization processes where the spaces between buildings frequently do not even register primarily as "spaces between buildings" but as horizontal visual landscapes unfolding in various directions. I may have gotten this notion from the townscape studies movement.
Canal and waterfall mill workforce neighborhoods on both sides of the Atlantic significantly predate Fishman's and this author's wave of lower-density higher-skill suburban growth.
The arrival of more than ten thousand relatively skilled French Protestant families of mostly weavers to Spitalfields and Bethnal Green and the surrounding area east of the London wall between 1585 and 1587 caused rapid development of a pretty comparatively suburban character. For a more planned version, the architect Inigo Jones' Covent Garden specifically attracted wealthy homeowners in the 1630s and 1640s when future Soho Square was still undeveloped and the West End was not a business center. For a less planned and more-exurban growth pattern I think of Quakers moving between the City of London and the more bucolic area of Stoke Newington north of town.

But stock trading also penalizes well-managed companies in slow-growing or more mature industries by giving them a higher cost-of-capital, just as it would if they were poorly managed. It seems a haphazardly blunt instrument for allocating liquidity to value generation. It piles on where rewards seem ready to be reaped, and makes it harder for mature sectors to renew or reinvent themselves.
I hope there's some insight beyond what I've got, but just from my experience: Sometimes having it blasting at the pressure you need while trying to get drowsy makes that process uncomfortable, but, after you've gained drowsiness it's not going to interrupt you and wake you (unless it starts leaking pressure against your face)
But if flat ones are harder to design right, then they're more likely not to be designed right, so we end up with a larger number of edge cases where they're going to perform worse.
It seems that a lot of projects decide on a diameter and then order a TBM for the expected materials that will have to be ground up [sic]. Would it be any significant savings (if you were in Great Britain for instance) to deliberately engineer your whole infrastructure design, and funding, and timeline, to use the exact same diameter as England's High Speed 2's TBM and then run that TBM after they are done with it? There must be a lot of single-use TBMs but I don't know what their builders reuse from one machine to the next.

Groves' deputy, Nichols, who was responsible for the loan, also told the story in more detail in 1987 memoir, "The Road to Trinity."
Because I agree with your general statement that market situations lose relevance once legislated, I think the principle more naturally extends to mean:
It is better to consider how to keep universities, whether research institutes or liberal arts universities, as a distinctive part of "the whole spectrum of techniques by which one generation transmits its insights and abilities to the next," Prof. Edsger Dijkstra's words. Not enshrine a set of commercial principles by which every piece of a spectrum must play.
Immediate job success is a fickle master; it would be a shame to LinkedInify any society. In 1996, Dijkstra said, [0]
> The University with its intellectual life on campus is undoubtedly a creation of the restless mind, but it is more than its creation: it is also its refuge. The University is unique in that on campus, being brilliant is socially acceptable. Furthermore the fabric of the academic world is so sturdy that it can absorb the most revolutionary ideas.
> But it is not only a refuge for the restless minds, it is also a reservation for them. It does not only protect the restless minds, it also protects the rest of the world, where they would create havoc if they were let loose. To put in another way, the fence around campus is essential because it separates two worlds that otherwise would harm each other. The fence ensures that we have relatively little direct influence on the world "out there", but we would be foolish to complain, for our freedom to be as radical as we like is based on the fact that, for at least the first 25 years, industry and the world-at-large ignore our work anyhow. Currently, there seems to be a world-wide tendency to try to lower the fence; the effort strikes me as ill-directed.
He had also been writing similar things in 1986 [1] and 1994 [2].
