I have been resisting buying a number of great hoodies from the assorted Historic Dockyard museum shops, on the grounds that I already have More Than Sufficient Hoodies, related to either ice hockey or musical theatre. R said obviously I need to wait for an ice hockey musical and get that hoodie.

Suggestions welcome for the topic / plot of such a musical.

far side of the moon

Image Credit: NASA / GSFC / Arizona State Univ. / Lunar Reconnaissance Orbiter

Explanation: Tidally locked in synchronous rotation, the Moon always presents its familiar nearside to denizens of planet Earth. From lunar orbit, the Moon's farside can become familiar, though. In fact this sharp picture, a mosaic from the Lunar Reconnaissance Orbiter's wide angle camera, is centered on the lunar farside. Part of a global mosaic of over 15,000 images acquired between November 2009 and February 2011, the highest resolution version shows features at a scale of 100 meters per pixel. Surprisingly, the rough and battered surface of the farside looks very different from the nearside covered with smooth dark lunar maria. A likely explanation is that the farside crust is thicker, making it harder for molten material from the interior to flow to the surface and form dark, smooth maria.

galaxy

Image Credit & Copyright: Robert Eder

Explanation: Big beautiful barred spiral galaxy Messier 109 is the 109th entry in Charles Messier's famous catalog of bright Nebulae and Star Clusters. You can find it just below the Big Dipper's bowl in the northern constellation Ursa Major. In fact, bright dipper star Phecda, Gamma Ursa Majoris, produces the glare at the upper right corner of this telescopic frame. M109's prominent central bar gives the galaxy the appearance of the Greek letter "theta", θ, a common mathematical symbol representing an angle. M109 spans a very small angle in planet Earth's sky though, about 7 arcminutes or 0.12 degrees. But that small angle corresponds to an enormous 120,000 light-year diameter at the galaxy's estimated 60 million light-year distance. The brightest member of the now recognized Ursa Major galaxy cluster, M109 (aka NGC 3992) is joined by spiky foreground stars. Three small, fuzzy bluish galaxies also on the scene, identified (top to bottom) as UGC 6969, UGC 6940 and UGC 6923, are possibly satellite galaxies of the larger barred spiral galaxy Messier 109.

Wyoming’s Grand Tetons and Jackson Lake

Photographer: Ray Boren
Summary Author: Ray Boren

Under a big blue sky, the morning sun illuminates a central portion of Wyoming’s majestic Teton Range, which is mirrored via specular reflection in a calm and equally blue bay of Jackson Lake in Grand Teton National Park. In this photograph, taken on May 23, 2025, the park’s namesake Grand Teton peak, topping out at 13,775 feet (4,199 meters) above sea level, is on the far-left side of the image, to the south. Blocky Mount Moran (12,610 feet; 3,840 m) rises prominently just left of center. 

The snow still covering the Tetons on this spring day makes it easy to envision the Pleistocene ice-age glaciers that helped carve the mountains’ jagged summits, cirques, and U-shaped drainages. The Park Service explains that the Teton Fault began tilting the range’s primarily granite mountain block upward about 10 million years ago while also dropping the valley of Jackson Hole. Although masked by snow in the photograph, almost a dozen glaciers remain in the park today, some moving and some mere remnants. They, and erosion from water, wind and gravity, continue to shape the dramatic terrain.

oursin: Hedgehog saying boggled hedgehog is boggled (Boggled hedgehog)

I was a little startled to see, quite so high up in the chart of UK's best and worst seaside towns, Dungeness. Which isn't really even a town (Wikipedia describes it as a hamlet), more a sandspit at the end of the Romney Hythe and Dymchurch Light Railway, famed for lighthouses, shingle beaches, nature reserves, Derek Jarman's Prospect Cottage, and a decommissioned nuclear power station ('Long journey ahead' for nuclear plant clean-up).

[A] barren and bewitching backdrop for a getaway. A vast swathe of this shingle headland is designated a National Nature Reserve, cradling around a third of all British plant species, with some 600 having been recorded, from rugged sea kale to delicate orchids. Exposed to the Channel and loomed over by twin nuclear power stations, Dungeness has, over recent decades, become an unlikely enclave for artists and a popular spot for day-trippers, horticulturalists and birders alike.

Or even
The ghostly allure of Dungeness, Kent. It’s an arid and mysterious place, yet it’s precisely these charms that captivate visitors.

Looking at the criteria scored on, it really is rather weird: completely lacking in the hotels, shopping and seafront/pier categories and not much for tourist attractions but scores high on peace and quiet and scenery.

Perhaps there is a larger number of people looking for this kind of getaway experience, invoking a certain eerie folk-horror vibe, than one would suppose. Not really a Summer Skies and Golden Sands kind of experience, take it away, The Overlanders.

Surprised that somewhere like Margate didn't rate higher.

Uni buddy R and I made it to Portsmouth last night, despite the best efforts of signal failures to scare us off. (Half the trains were showing as cancelled around 3pm; by the time we actually got to Cambridge station at 5pm things were looking better; by the time our train got to Finsbury Park it looked like service was nearly restored and we continued to change at Three Bridges as originally planned.)

I was working up until about 4pm, with a couple of colleagues very amused that a) I didn't start packing until a gap between meetings at 2pm, and b) my "girls weekend" consists of naval museums and ice skating.

We had an easy walk to our hotel in the midsummer twilight, and settled in to our respective rooms. I'm doing admin until R texts me she's ready for breakfast. And then: the Mary Rose! (who else has formative childhood memories of watching it being raised?)

One in 32 births in 2023 [in the UK] were the result of in vitro fertilisation, up 34% from one in 43 in 2013, according to the Human Fertilisation and Embryology Authority (HFEA)

I admit this sounds rather startling, but then, being a historian of reproductive health among other things, I think of the fact that though we sometimes think our poor ancestresses were popping out progeny pretty much nonstop until death or menopause arrived, in actuality, fertility and subfertility were A Thing, historically. (Let us consider certain famed historical examples and a plethora of folktales on this theme.)

I have remarked heretofore about the assumption that Wo Unto The Sperms of the Modern Man, They Are Weak and In Decline, when I cannot see that there is any sound baseline of what the average male's average sperm count was and whether the little swimmers were even in prime condition at that even a very few decades ago. One assumes that any samples preserved in sperm banks (if they are and supposing they have not themselves deteriorated over time) would have been prime stuff from healthy young specimens. (Though given some of the stories that have come out about dodgy fertility docs, perhaps not.)

So this is not necessarily a story of Wo Wo Fertility B Declining, with side-order of Wymmynz B selfishly waiting Too Long to progenate, but of a problem which used to exist and was at the very least Not At All Easy To Fix (hopes and prayers, mostly, and try to relax....) has some chance of being resolved.

Okay, some percentage is presumably LGBTQ+ couples/constellations forming families.

And some of it is Older Mothers though again, historically, women have gone on Havin Babbyz well into their 40s and (Journal of Anecdotes Told to Me By Committee Members of Reproductive Health Charities) these days a significant % of abortions in the UK involve women who have misleadingly supposed from media myth that At Their Advanced Age their ovaries have shrivelled up and their fertility fallen off a cliff.

Though this is interesting:

The number of women freezing their eggs also increased sharply, with cycles up from 4,700 in 2022 to 6,900 in 2023. Egg freezing increased most among women in their 30s, but the number using their stored frozen eggs remained low, the report said.

Hmmmm.

Summary Author: Rui Santos

The night sky and planetary alignment featured above was captured from Pinhal de Leiria, Portugal on February 28, 2025. I decided to view the alignment from here because I knew I'd have a clear view of the horizon. Since the planets were stretched out across the sky, I had to do a panorama and try to avoid light pollution (lower left and lower right) from surrounding cities and towns. Venus, Jupiter, Mars and Uranus are included above, but because I wasn't able to arrive as the Sun was setting, Saturn, Neptune and Mercury aren't in the frame.

At bottom center is the Crastinha Lookout Point, one of several watchtowers in the Forest of Leiria. The building to its right is the reconstruction of what used to be the guard's house, dating from 1883. This tower is still in use today.

closeup of a crystal

Kunzite is the pink to light purple gem variety of the mineral Spodumene. Spodumene is a common mineral, but only in several localities does it occur in transparent gem form. The main gem form of Spodumene is Kunzite, the other is the rarer Hiddenite. Yellow and colorless gem forms of Spodumene also exist, but are not commonly faceted as gemstones. Kunzite has a lovely pink color and is becoming increasingly popular in the gemstone market.

Chemical Formula: LiAlSi2O6
Color: Pink, Purple
Hardness: 6.5 - 7
Crystal System: Monoclinic
Refractive Index: 1.66 - 1.68
SG: 3.1 - 3.2
Transparency: Transparent
Double Refraction: .015
Luster: Vitreous
Cleavage: 1,2 - prismatic
Mineral Class: Spodumene

All About:
Kunzite is a relatively recent gemstone, having been first discovered in the 20th century. It was first found in the pegmatites of Pala, California, in 1902, and is named after the famous mineralogist George F. Kunz who first identified it. Though it wasn't until the 1990's that this gemstone became a more mainstream gemstone, having been used only as a collectors gemstone prior to that time.

Kunzite is a very attractive pink gem, but is notorious for its habit of color fading in prolonged exposure to strong light. Although the color-fading effect is very slow, most people still prefer to wear Kunzite jewelery in the evening to avoid sunlight exposure. Kunzite is regarded as an evening stone for this reason.

Kunzite deposits are quite extensive and yield large amounts of this gemstone, thus making it very affordable. Extremely large and flawless crystals of Kunzite have been found, and these can yield very large and flawless faceted gemstones.

The perfect cleavage and splintery fracture of Kunzite makes it a difficult gemstone to facet. It is very sensitive to knocks and will chip if hit too hard. Kunzite is known for its strong pleochroism, showing lighter and more intense coloring when viewed at different angles. For this reason, it is always cut to show the deepest pink color through the top of the gem. The deeper pink the Kunzite, the more valuable it generally is.


Uses:
Although Kunzite is a relatively soft and delicate gem, and can fade after prolonged exposure to light, its appealing color makes it a popular gem. Small gems are not commonly cut from Kunzite because of its cleavage and strong pleochroism. It is most often used as a pendant stone and as a large decorating stone on ornamental objects. It is less commonly used in rings, necklaces, or other jewelry items where small stones are required. Less transparent stones are sometimes cut into cabochons and beads.

Varieties:
Blue Kunzite - Light blue to bluish green transparent form of Spodumene.
Yellow Kunzite - Yellow transparent form of Spodumene.



History and Introduction:
Kunzite is the pale pink to light-violet gem-quality variety of the pyroxene mineral spodumene, a lithium aluminum inosilicate. Kunzite was first discovered in Connecticut, USA, and was named after George Frederick Kunz (1856 - 1932), an American mineralogist and the former vice president and buyer for Tiffany & Company. Kunz was a legendary New York jeweler and colored stone specialist, and he was the first to comprehensively describe the stone in 1902.

Although it was first discovered in the USA, most of the current supply of kunzite is found in Afghanistan and Pakistan. Kunzite is closely related to hiddenite, the yellow-green member of the spodumene gemstone family which was also discovered and named after an American mineralogist, W. E. Hidden; as well as the classic golden to yellow color gem-quality spodumene. Kunzite is known to produce gemstones of great size. In fact, it's not uncommon to find fine quality stones weighing 20 carats or more. Kunzite and the entire spodumene group are important industrial sources of lithium, which is used for the making of medicines, ceramics, mobile phones and automotive batteries.

oursin: Photograph of small impressionistic metal figurine seated reading a book (Reader)

What I read

Finished Cluny Brown.

Defaulted to rereads of Agatha Christie, The Murder in the Mews, The Murder in the Vicarage, Towards Zero and Taken at the Flood.

Somebody on my reading list mentioned Meg Moseman, The Falling Tower (2025) - spooky goings on at Harvard involving the ghostly presence of Charles Williams among other things. May be just me but I found it all a bit rushed: then I realised that my bar for Weird Stuff Going On In Academic Setting was set very high indeed years ago by Pamela Dean's Tam Lin (I considered that there may also be issues around Times Have Changed).

Managed to find my copy of GB Stern's Summer's Play aka The Augs (1933/4) though couldn't lay my hands on The Woman in the Hall alas. Really very good. A problem for republishing may be a few casual allusions to blackface seaside entertainment of the period.

Because I've never actually read it though I've read other of her works, and it was being inaccurately discussed recently as lost, overlooked, neglected etc, Dorothy Canfield Fisher, The Homemaker (1924). This is what, like 40 or so years before The Feminine Mystique and 'the problem that has no name'?

On the go

Just recently republished (collation of two previous collections published in limited editions in 1994 and 1997), Simon Raven, The Islands of Sorrow and Other Macabre Tales. So Simon, very Raven.

I started John Wiswell, Someone You Can Build a Nest In (2024) which I know has been widely admired but I'm somehow just not vibeing with it.

Also well on into first of books for essay review, v good.

Up next

Dunno. The new Barbara Hambly arrives pretty much just as (DV) I am off to a conference.

So, today I had a physio appointment at the far from eligible hour of 1 pm, what is this even, do these people not have lunch hours? also it was at the uphill all the way clinic.

Anyway, I got there in very good time, and was able to ascertain the bus stop that would actually take me in the right sort of direction for getting home.

(It was actually quite a nice walk past people's flowering gardens or council floral bits.)

And it was a very good and useful session, with a senior person as well as my usual physio, and I think we may be getting to some habit-changing things that might improve matters.

So after I had come out I went and caught the bus, which is one that goes across rather than up and down (so much of London Transport being designed on the principle of getting people into Central London and back out again) and it is a nice bus that goes past Highgate Cemetery, even if it is the newer bit, and the hospital, and okay, ends up at a slightly non-intuitive place behind Archway, but I was able eventually to locate the relevant stop for an onward bus.

And in other news, I have whizzed off an application for the Fellowship I mentioned and have had several kind offers from FB friends to provide letters of recommendation.

Hmm, last month I linked to things I'm not making, and in March and April I noted putting things on hold.

Lille Kolding has become the first knitting project for which I haven't minded a preponderance of variations upon 1x1 ribbing. The current section is part ribbing and part brioche; the latter is sort of ribbing with tuck stitches. Most likely, the project benefits from being knitted only amidst waiting (not daily).

The blanket project sat quietly in a bag from Dec 2024 till May 2025 while its boredom factor receded. It's become my main knitting at home. At 200+ g (close to half a pound), it's too bulky to be carried around on its 60" = 152 cm circular needle, and it's easier on my hands alongside notetaking for classes than most other yarn-centric options would be. I'd like to finish it while the weather is warm, so that it actually dries after its initial wash.

Shortly before the blanket project went on hold, I began and paused a different multi-hue project. It seems that my brain can keep only one colorful project in working memory at a time---and the blanket will be completed; the other project's yarn will be repurposed. It's a positive outcome, regardless: I began the now-repurposed thing because I'd thought that I couldn't knit blankets. It was to be scarf-sized.

On the possible academic library etc access thing, somebody has kindly pointed me at the Institute of Historical Research Non-Stipendiary Fellowships, which look fairly much the thing -

- except that the window for application closes on Friday, and besides getting an application together I need a letter of support testifying to my 'interest in research, good faith and behaviour' (at least, unlike the Bodleian, there is no cavil about naked flames).

So there's that.

In other, is this good or bad, had an email from person on committee of Society with which I have had associations in the past and published in their organ (hurhhurh) saying a) they have come across a piece I published in that organ and might I like to give a paper at their upcoming conference?

Well, I could possibly throw something together -

And b) the archives of this Society and a precursor organisation in which I am particularly interested have been deaccessioned by the Academic Institution where they were held (which has, I remark, form in this matter), and returned them to the Society.

I have, in what I hope was a reasonable tone, exhorted them to put them in another repository pronto, I recommend X, where they will be with archives of related org, also the vast and important collection previously unhomed by the Institution in question.
