After a chaotic and problematic week with work I decided to have saturday off.
Leaving the hotel early in Delft I stepped on a train, off the train and onto another and found myself in Alkmaar. When I last visited in was under ice and snow.
In 2015 the station was expanded to cope with traffic growth (Alkmaar is an expansion city within the national plan). Between 2014 and 2016 the north side of the station area was altered significantly. A 3,000 space multi-level bike park was added. A new bridge utilising large expanses of glass plate has been built over the tracks and it is from this that I took these photos helped by a wonderfully clear spring sky. The bridge gives great views of the Victorian parts of the town and the newer parts.
Alkmaar Station opened on 20 December 1865 when the railway opened between Alkmaar and Den Helder. This was the second railway opened by the Hollandsche IJzeren Spoorweg-Maatschappij after the Amsterdam–Rotterdam railway. The line through Alkmaar was on the Staatslijn K railway, built by the Dutch state between 1865 and 1878, designed by Karel Hendrik van Brederode.
All these finders are not designed to have the optical axis (crosshair) parallel to the tube. Makes use as polar alignment scope problematic. I checked these, 1/2 to 1° off.
Got lucky using Celestron finder for polar alignment, it was off in the right direction www.flickr.com/photos/edhiker/3654462866/
Conclusion: sight tube is better than maladjusted optics for quick polar alignment.
------
When polar alignment scopes come from the factory, wherever that is, their
reticles are usually not centered. This makes polar alignment of the mount
more difficult. tech.groups.yahoo.com/group/ap-gto/message/5173
----
You need to be able to point the polar axis of the mount at something
terestrial, like the top of a telephone pole, water tower, etc. that isn't
going to move and is at a 'down the street' distance. This means building a
simple wood gig to tilt the telescope so the polar axis is more
horizontal. Use just the mount, no payload and no counterweight shaft or
weights.
Put the Polar alignment scope in the mount until tight. Then get comfortable
and sight through the scope until the object (top of t-pole, etc.) is in the
center of the PAL scope field. Now rotate the mount around the polar axis by
hand and watch the object in the PAL scope. If the object stays centered when
you rotate the polar axis all the way around, the PAL scope is properly
aligned. More than likely, the object will wander or wobble around as the
polar axis is rotated. Using the three small set screws on the PAL scope,
gently loosen one and tighten another until you've moved the center of the
reticle to where the center of rotation appears to be. Rotate the polar axis
again to see if the wobble is less or more. This is a trial and error
approach, but should take only a few cycles. When the polar axis is rotated
and the object stays centered, the PAL scope is now centered.

This species correct name is proving problematic... it was long known and accepted under the name Cattleya eldorado Linden (ex van Houtte) since around 1869. Then, by the mid 1980's, some authors, based on a G. Braem proposal, started claiming that the correct name should be that given by Barbosa Rodrigues in 1877, Cattleya tricopiliochila, based on the fact that the name 'eldorado' was illegitimate under the ICBN rules. By the turn of the 2000, van den Berg published a paper showing that the correct name for this species was Cattleya wallisii not 'eldorado', nor 'trichopiliochila', based on a 1865 publication by Linden, where he called this species Laelia wallisii. Van den Berg also points out a comment of Reichenbach f., published in the Gardeners’ Chronicle (1882) where the botanist would implicitly have transferred it from the genus Laelia to Cattleya, thus coining Cattleya wallisii, this being the correct name to be used. Kew (Monocot Checklist) doesn’t accept that Mr. Reichenbach has made the transfer, preferring to state that it would have been done in a Rollison Nursery catalog of 1876. To make stuff a little more interesting, the flower Linden ‘described’ as Laelia wallisii, the type of the species so, was entirely white, except for the yellow in the throat and part of the lip, which means that, according to van den Berg’s proposal and Kew Monocot Checklist, if you accept the name Cattleya wallisii, then you’ll have to also accept that the type of the species formerly known as eldorado is white, the flower you see in this picture, and all other color forms are varietas of this type, including the ordinary lavender color.

Zaandam.
Zaandam Station and Inntel Hotel . The hotel opened in 2010 in Zaandam . It is a striking building because the exterior consists entirely of a stack of almost seventy loose Zaanse houses, executed in four colors Zaans groen. The building was designed by Wilfried van Winden. The area of the station, hotel and Gedempte Gracht was redeveloped into a multi level modern complex but harking back in its design to the Netherlands of the past.
Tentaculite fossils in limestone (the reddish brown areas are from iron oxide staining)
Tentaculites are problematic fossils - their high-level taxonomic placement is uncertain, but they may be molluscs. Tentaculite fossils consist of small to very small calcitic shells. The shells are straight to slightly curving and are slightly tapering tubes. The pointed end of the shell is closed. In some forms, the pointed end is slightly bulbous, with an apical spine (usually broken off). Externally, tentaculite shells usually have ringed ornament and thin, delicate, longitudinal striations.
The tip of the shell is the embryonic part. After that is the juvenile portion of the shell, which consists of internal septa, or walls that divide the shell into chambers. Septa have no external expression and number 5 to 20 in one specimen. The adult portion of the shell is nonseptate - it is referred to as the living chamber, which occupies more than half the entire length of the shell. No aperture-like structure has ever been found at the distal end of the shell.
The soft-part morphology of tentaculites is poorly known. X-ray images of specimens from the Lower Devonian of Germany seem to show multiple "tentacles" protruding from the large end of the shell. Muscle impressions on the interior have been reported in some tentaculites.
Tentaculites are entirely extinct - their geologic range depends on how inclusive the term "tentaculite" is. Tentaculites first definitely appear in Ordovician rocks. Their maximum abundance and diversity was during the Devonian.
Tentaculites were entirely marine. They are known from shallow and deep-water deposits. Larger, thick-shelled forms are local in their distribution, and so appear to have been benthic. Smaller, thin-shelled forms have world-wide distributions, and so appear to have been planktonic. Planktonic forms, such as the styliolinids, may not be tentaculites at all. Sometimes, encrusters are found on tentaculite shells. The distribution of encrusting organisms suggests that benthic tentaculites had the apex of the shell pointed downward and the aperture was upward during life. Almost all tentaculite fossils are found parallel to bedding. Very few have been found with the pointed end of the shell vertically inserted into the sediments.
Classification: Animalia incertae sedis, Tentaculita, Tentaculitida
Age: possibly Devonian

Another lovely terracotta station, which is unfortunately wider than it is tall (which is problematic for map cards).
On Tuesday 15 July 2025, officers and partners across the City of Manchester came together to patrol the city’s most problematic areas in a bid to tackle anti-social behaviour (ASB).
As part of the recently launched Home Office Safe4Summer initiative, which seeks to identify hotspot areas for ASB and tackle them with high-visibility and problem-solving policing, GMP officers and partners from Manchester City Council took to Piccadilly Gardens.
The newly formed Piccadilly Gardens Team, made up of eight police constables and Sergeant Jon Wyatt, was formed to front a multi-agency response designed to tackle ASB, and make Piccadilly Gardens hostile to criminality and a safer space for people to live, work and socialise.
During their patrol, specialist officers acted on intelligence and within minutes, uncovered two concealed bladed articles from the area. Police dog Kylo, was also on hand, aiding officers in the search for drugs and weapons.
A total of eight arrests were made within the gardens over the course of the day, for a range of offences including immigration offences, public order, robbery, and breach of Criminal Behaviour Order (CBO). Partners including Manchester City Council, CityCo, TfGM and Travelsafe joined GMP officers and staff on the ground alongside councillors Joan Davies and Pat Karney.
Councillor Garry Bridges, Deputy Leader of Manchester City Council, said: "As a council we work hard to ensure a positive experience for residents, visitors and businesses in Piccadilly Gardens, which is a much used and important gateway at the heart of the city centre.
“Together with our Neighbourhood Team, Licensing and Out of Hours Team, Anti-Social Behaviour Action Team and Cleansing Team we joined our colleagues at GMP to engage with businesses, residents and visitors in Piccadilly Gardens.
“We're really pleased to support these partnership action days with GMP, which demonstrate our joint commitment to making Piccadilly Gardens a safe and welcoming public space."
Chief Inspector Michael Tachauer co-ordinated the operation, deploying specialist officers to conduct sweeps with multiple weapons found hidden on roofs and in planters.
Chief Inspector Tachauer said: “Maintaining a good relationship with local businesses and our partners is key, as they are our eyes and ears on a daily basis. We meet and discuss issues once a week, seeking to problem-solve and focus on where we can make the biggest difference across the city.
“This day of action is just one example of the ongoing work our officers are carrying out every day, as part of our commitment to make Piccadilly Gardens a safer place for everyone who lives, works or visits the area”.

Some species of moss are problematic on orchid mounts, but I am fond of this species. It is easy to manage and generally doesn't smother plants as some others do. In addition it slows down the drying of roots ever so slightly, instead of keeping them soggy.
The long series of films, videos, engaged interventions in public space, performances, and object installations provide a consistent testimony to the power of the themes reflected. For many years, Vladimír Turner has persistently pointed out problematic, and often strongly cautionary, moments of Anthropocene civilisation in various places around the world. The enchanted mechanism of consumption-production, the deceitfulness of marketing strategies, the extraction of non-renewable resources, the brutal devastation of the landscape, mass tourism, the misconception of the possibility of shackling the organism of a big city to a structure of order, gentrification, homelessness, inhumane methods of political systems. In fact, the theme of the essence of pure humanity, personal and social responsibility towards the landscape, nature, and a sustainable way of life based on local self-sufficiency is recalled again and again. He points out the themes through matter-of-factly simple acts. This makes the awareness of the necessity of individual engagement all the more intense. Although his conceptual works have an activist character, often dealing with the subversion of paradox, the expressive power of the pure artistry cannot be ignored. Through his installation for the Veleslavín station, Vladimír Turner verbalises the sculptural situation with the themes of sustainable mobility, fossil fuels, international trade, the relationship of motoring vs. train transport, and exodus and nomadism as consequences of climate change. He chooses the form of a specifically modified Volvo car, with an appeal to the constant presence of the potential of a natural human resource. The ideas of the installation are directly related to the genesis of the artist’s intended film, in which he finds himself in the role of an aborigine, the last survivor on planet Earth, who begins to build everything necessary to live from the garbage all around him. “System Change! Not Climate Change!” (VT)
Goal: Create a small, pretty much stud legal triangle.
As I was trying to figure out how close this was to legal, counting studs and doing math, the numbers were close, but they weren't quite lining up with what I saw in ABS. The problem with counting the studs is that there is an excess of a half stud's length from the vertices of the triangle on each piece. In the example above, the lower left and upper right aren't actually part of the mathematical triangle. By counting the stud spans, I was able to estimate that the legs were less than 0.3 mm long compared to the hypotenuse, which seemed much more in line.
(a^2 = b^2+c^2, using 40mm for the hypotenuse span and a decimal approximation of sqrt2/2, equals about 28.284mm per leg. If the lengths were perfect, they'd measure an even 28mm. Still, I think this may be within fault tolerances for Lego elements.) (And apologies to every math teacher I've had, I probably butchered that explanation.)

I am the last advocate for reducing texts, scriptures and languages to mere graphic forms. The whole dimension of the text's meaning, histories, combinations, connotations, sound and craft is disregarded. What is more problematic is that I am ignoring the power of words to move and persuade people.
After first year and my first internship, I felt slightly disillusioned and confused by what Architecture meant to me. I took a trip to Myanmar and the trip recalibrated a lot things. I found it particularly grounding and inspiring for some of the things that I want to achieve in the future.
The spatial and formal organisation of the Burmese language in signage was something I found very compelling. At least with the handwritten texts, so much thought and effort was put into crafting every character. You see pencil marks, underlays, brush strokes and outlines. There is a combination of type faces and textures to create visual impact in different programmatic contexts that I find fascinating.
The Burmese name for the round script is "ca-lonh", literally translating to "round text". There are 33 main characters in the Myanmar language. Instead of words that are formed by a combination of alphabets (like in English), this language makes use of additional vowel shift symbols, tonal change symbols and consonant modification symbols. The rounded form of the characters is a result of the use of palm laves a the traditional writing material. Straight lines and forms would tear the leaves.
By compiling this, I am exposing my status as alien and an outsider. However, the focus on the visuals may have the inverse effect of celebrating the text, for text's sake, specifically, it is celebrated as visual form and not just a sign that says "eggs", or something.
Regardless, I tried to interpret the scope of "text" in a broad but focused way - text, in its literal form, text in prayer, text in recitation, text in architectural program (the stupas of Kuthodaw Pagoda). Photos are arranged in chronological order. The journey started in Yangon, then upstream along the Ayarwaddy river, to Mandalay and Bagan, then back again to Yangon.
These photos aren't really anything special in terms of photography, and I am not going to attempt to make sweeping claims about directing a new visual order, but as a composite they attempt to represent my yearning to celebrate a culture of appreciation for the process driven intensity in text making and in the creation of form.
Tentaculites gyracanthus (Eaton, 1832) - tentaculites (= the small, ridged, conical shells) in fossiliferous limestone from the Devonian of New York State, USA.
Tentaculites are problematic fossils - their high-level taxonomic placement is uncertain, but they may be molluscs. Tentaculite fossils consist of small to very small calcitic shells. The shells are straight to slightly curving and are slightly tapering tubes. The pointed end of the shell is closed.

The examples seen here are Tentaculites gyracanthus, the first-named tentaculite species in America - it was originally misperceived as a fossil sea urchin spine. This rock specimen comes from New York State's Manlius Limestone, from which another tentaculite species is also known - Tentaculites simmondsi.

A History of the Puerto Rican People, in Three Panels
As Elizabeth Garcia Gonzalez, the Executive Director of Centro de la Comunidad conducted me on the grand tour, she showed me this triptych (a work of art which is divided into three sections) currently in the area of the former altar. Painted in the late 1970s, it depicts some of the history of the Puerto Rican people. It is a little problematic, now, as it relates almost exclusively to the Borincano people of that one island, showing the subjugation of the Taino/Arawakan people by the Spanishconquistadores, and the later development of their culture. Today, the Centro de la Comunidad provides support to all the Spanish-speaking people of the Americas, so perhaps some additional art might be appropriate.
Unfortunately, the full name of the artist is lost, with only what appears to be a surname in the signature. It looks like 'Marple' or 'Maaple', the latter a little less likely, since it is a Hindi surname, and we should probably be looking for someone closer to the West Indian area. The painting dates to 1978, so it's quite possible the artist is still active. Any help would be appreciated.

This crappy learner protal waste my whole day! It shows a "Semester 2 Timetable" for me to view and there's nothing but "coming soon". Later I check back and there's a survey form. I fill them all and it ask me to login. But everytime it said it's not valid. So I waited and waited from 10 am to 9 pm and finally i got what i want...
