Solutions to my last two maths problems, some sciencey pieces, a petition and some photographs.
This post includes solutions to the problems I posed on Saturday, and a few other things from various sources.
SPACE STATION DODECAHEDRON
Here is the question as a reminder:
Here is the answer:
Here is a splendidly concise solution from David Vreken:
A VARIARION ON THE MALFATTI THEME
Here is the question:
Here is the answer:
In the 19th century Malfatti conjectured that the way to maximise the area of a triangle you could fill with three circles was to fill in the three largest circles that touch specifically two of the three sides. Although he was not alive to be humiliated it turned out that he was not merely wrong, his proposed solution has been proved not to work for a single triangle. The solution that always works is first put in the largest single circle that touches all three sides that you can, then fill in the largest circle you can in the remaining space and then do so again. In an equilateral triangle the difference is small, but in a long thin isosceles triangle it is quite substantial.
Here is Jeremy Galvagni’s published solution:
SCHOOL REFUSAL SYNDROME PETITION
This on the official site for petitions to the UK government, which means that you have be a UK citizen to sign it. Please click the screenshot below to sign and share it if so minded:
David Quammen, a good writer and a useful scientist to know about if you are planning an A to Z post, has a new book out on the subject of evolution, and Jerry Coyne of whyevolutionistrue has provided a very detailed review of it.
Finally, a letter to the Guardian signed by 60 well known environmental campaigners declaring their unwillingness to debate with climate change deniers, and why they are unwilling to do so. Below is the opening to the letter (please click to visit the original) and a list of signatories:
Continuing my account of Marxism 2018, with the second and third meetings of the Thursday.
This post continues my coverage of Marxism 2018, which started with an introductory post. In this post I cover the second and third meetings of the opening day, which for me were Camilla Royle on the Politics of Science and Ken Olende on What Was Unique About The Translatlantic Slave Trade.
CAMILLA ROYLE ON SCIENCE
Camilla’s actual title was “Is science political?” Most scientists would like the answer to this question to be no, but desirability and truth are two different things. Camilla demonstrated many examples of science being coopted for political ends. This was an excellent talk and it set the stage for a splendid discussion.
KEN OLENDE ON SLAVERY
This talk was accompanied by slides which makes it easier to convey an impression of the ground covered.
I am autistic myself, and also branch secretary of NAS West Norfolk. This entry is a very appropriate starting point because it was my diagnosis and the role I then had running a support group for Asperger East Anglia that led me to create this blog.
B IS FOR BOOKS
I have always loved books, and am a very voracious reader. In addition to my own collection I am a regular user of several of Norfolk’s libraries, and yes I do use them to borrow books.
C IS FOR CRICKET
I have been an enthusiastic follower of cricket for over 3o years (my attempts at playing the game foundered on a chronic lack of talent). The fact that my employers had an auction yesterday and have another on Saturday means that I am off work today, and therefore able to listen both installments of the Women’s T20 double header. Here is the feature image from Saturday’s upcoming auction:
D IS FOR DETECTIVE STORIES
This is an extension of my love of books as a whole. I regularly borrow large quantities of detective ficition from thbe libraries. Among my very favourites are Edward Marston’s Railway Detective stories.
E IS FOR EAST RUDHAM
The village in West Norfolk where I began to rebuild my life after mental health issues had nearly destroyed me. I lived there for just over five years and was a regular visitor until my parents recently moved to Cornwall.
F IS FOR FERRY
I have travelled on many ferries in my lifetime, but the one I particularly think of nowadays is the Lynn Ferry which has been running for over 800 years.
G IS FOR GREECE
I first visited Greece for a family holiday about 35 years ago and have been back mnay times. It remains a favourite holiday location. I have produced a number of posts about my most recent visit.
H IS FOR HISTORY
One of the many subjects I enjoy reading about. One of the reasons I enjoy going to Greece so much is the presence of so many historic sites.
I IS FOR IRRELIGIOUS
I have been a staunch atheist for my entire adult life. For those who take the approach that the Northern Ireland census form used to I am a “catholic atheist” – that being the specific religion that I rejected. To paraphrase Richard Dawkins most people are as atheist as me about almost every god who has ever been believed in – I just go one god further than they do.
J IS FOR JOURNEYS
I love travelling, and being a lifelong non-driver am able to make good use of almost all my journeys – if the route is not familiar to me I will be observing the scenery and taking photographs, and if it is it represents reading time.
K IS FOR KERNOW
Kernow is the Cornish name for Cornwall (this is the only entry in my A-Z that overlaps with The Cornish Maid’s), and although unlike the person who inspired this post I do not live there I have been there a number of times over the years and my parents have recently moved to that part of the world. It is a Cornish picture that appears on the reverse of my personal cards:
L IS FOR LONDON
I grew up in London, and still visit the place on occasion. Also, I run a London Transport themed website, www.londontu.be. I will be back in London during the latter part of next week, for Marxism 2018 which runs from Thursday to Sunday.
M IS FOR MATHEMATICS
Another lifelong interest, and something that I am very good at. Here is a frecnet problem from brilliant.orgthat took my fancy:
N IS FOR NATURE
Nature has always been very important to me, and I love being out and about in nature with my camera for company. My name is often to be found among those supporting campaigns to protect nature, and as a thoroughgoing internationalist I take pride in having been the first non-Swede to sign the online petition to save Trosa nature.
O IS FOR OVAL
Because of their shape many cricket grounds have Oval in their name. The two with which I am most familiar are The Oval, in South London not very far from where I grew up, and served by two stations, Oval and Vauxhall; and the Adelaide Oval, which owes its name to a transplanted Surreyite who suggested it because he wanted to be reminded of home. Of the innings I have seen live at the ground the most memorable at either of these two venues was played by David Gower in 1990. England could do no better than draw the game, which as it happened was enough to give them the series. Gower made 157 in that innings, and by the time he was out the draw had long since been secured.
P IS FOR PHOTOGRAPHY
This is a hobby of mine, and also something I do at work. Here are some recent pictures:
Q IS FOR QUIZ
With my eclectic interests and retentive memory I am pretty good at quizzes (unless they are overloaded with questions about pop music), and generally enjoy taking part.
R IS FOR RAILWAYS
Railways are one of my special interests. I have travelled on railways in many different countries and have also built up a decent collection of railwayana. I may add to my collection on Saturday.
S IS FOR SCOTLAND AND SWEDEN
These are two of my favourite countries to visit, both very scenic. I could find no way to split them so I have decided to honour both places.I have produced a number of posts about both Sweden and Scotland. Here are a couple of pics: A view from Strome Castle, Scotland
This river is in Northern Sweden.
T IS FOR T20
Yes – another cricket related entry. T20 (where each side bats for 20 overs) has been a great success since its introductiuon in 2003. However the new 100-balls per side competition is being too clever by half (and consigning the County Championship to the start and end of the season when conditions are least suitable for long form cricket).
U IS FOR UNIVERSE
I find it fascination reading theories about our universe, its possible origins and its possible place in a wider cosmos. I also find the history of how we moved from considering our planet to be at the centre of a fixed universe to recognising it as pale blue dot (hat tip to Carl Sagan who wrote a book of that title) in the immensity of the cosmos to be fascinating.
V IS FOR VARIETY
One of the things I enjoy about my current job is that there is plenty of variety there. I am firmly in the camp of those who say that variety is the spice of life.
WHY EVOLUTION IS TRUE
Jerry Coyne’s 2009 book with that title remains a firm favourite (along with his more recent Faith versus Fact), and it is also the title of a blogrun by Professor Coyne that I follow.
X IS FOR EXHORT
As I near the end of this post I exhort you to produce your own version – it is time consuming but fun. You have seen my version, and if you followed the opening link you have seen the version that inspired me to take on this challenge – now go and do likewise!
Y IS FOR YARBOROUGH
This is a bit of a cheat – it is my way of mentioning the game of Bridge which is a firm favourite of mine. A yarborough is a hand with no card higher than a nine and 4-3-3-3 distribution, and is named in honour of Lord Yarborough who had all bridge players at his house contribute a guinea to a kitty, while if someone had the misfortune to be dealt the hand that now bears his name they got 1,000 guineas (he was on to a winner – the actual odds against the hand coming up are 1827 to 1). I do not get to play very often but I am a pretty good player of the game.
Z IS FOR ZOOM
A zoom lens can be a real boon for a photographer (my current camera has a zoom capacity of up to 60X) – a little tip from experience is to not stretch the zoom lens right to its limits – leave a bit of space around whatever you are photographing (you can always crop it out during the editing process). This post was inspired by a Cornish blogger, so I end with a Cornish picture.
A mixed bag of bits and pieces from around the net and some of my own stuff, including photographs.
Yes folks it is time for sharing post, including some of my own photographs. I have a lot of interesting stuff to share, starting with…
AN ANNIVERSARY OF SHAME
The bodytext of this section is in #RedInstead because it relates to Autism. To be exact, today marks 20 years since Andrew Wakefield published his “research” indicating a link between autism and vaccines. One impact his decision to go straight to the press without having his “research” peer reviewed first (it was badly flawed, and that is being kind) had was to cause measles to become a significant factor in parts of the UK as parents declined to have their children vaccinated. There can be no comparison between autism (a neurological DIFFERENCE – and don’t forget that different is not a synonym for lesser) and measles (a dangerous illness). However, in the minds of some parents, fear of autism has been sufficient to prevent them from vaccinating. Mr Wakefield has since decamped to the US (Texas to be exact), and he has just weighed in on an election in his new home, supporting the challenger against the current incumbent, republican Sarah Davis, who has supported vaccines. I am not USian, nor based in the area where this election is taking place, but if there is anything that could induce to me to vote for a republican it would the likes of Wakefield urging a vote for their opponent.
I finish this mini section back here in Norfolk, bringing up a topic close to my heart. Stagecoach are closing their King’s Lynn depot on April 30th (a king sized betrayal of Norfolk Green, the company they bought to get that depot) and will not be running any Norfolk routes thereafter. This leaves Konect, Lynx Buses, First, Sanders Coach Services and West Norfolk Community Transport to pick up the pieces. Our bus routes are very important to us, not least since thanks to Dr Beeching our county has no train routes to speak of. Thus I bring you a 38 Degrees petition calling on the council to work with these companies to ensure that the Coasthopper service (under threat of being entirely shut down) keeps running. Please sign and share the petition, via the screenshot below:
Happy new year everyone. This post will give you a few hints as to what you can look forward to in 2018 on aspi.blog.
ASPI.BLOG STYLE GUIDE
Headings will generally be in a cycle that runs red/green’purple, although this is subject to variation in certain circumstances.
Body text will always be in black unless I am writing about autism, in which case I will use #RedInstead.
When sharing content from another site I will always link to the host site and the specific post and where possible will mention the author by name – such links will be a different colour from regular body text and will be both bold and underlined.
It will be a very rare post that does not congtain photographs.
LIKELY SUBJECTS FOR 2018
I will also probably find other things to blog about in 2018.
A COUPLE OF CLOSING QUESTIONS
Please feel free to use the comments to answer the questions below?
A mixed bag of a post, featuring local politics, libraries, autism, science, nature and photography.
Welcome to this post in three parts. I am going to start by mentioning a local election that took place in my area today and in which I voted, then I will be mentioning an event that will be taking place at Gaywood Library (one of four such establishments in Norfolk that I visit at least semi-regularly) and I will finish up with some links to do with nature which will lead naturally to some of my photographs.
A FORCED BY-ELECTION
The election in which I voted today happened due to the laziness and arrogance of the incumbent councillor, who in spite of living just across the road from the Town Hall never attended meetings.
Four candidates were in the contest, in alphabetical order:
Rob Archer of the Green Party Francis Bone of the Labour Party Helen Russell-Johnson of the Liberal Democrats Mike Taylor of the Conservative Party
In the ordinary course of events my inclination, especially given that the displaced councillor had been from the Labour Party would have been to vote for Mr Archer. However, the Liberal Democrat candidate happens to be my aunt. Therefore I voted for her.
I have started this post by covering this election for two reasons:
I want to make it clear to the Liberal Democrats that I voted for my aunt IN SPITE of the fact that she was representing them not because of it.
Also, just in case Mr Archer happens to be reading this, I hope he will take it as both explanation and apology for not having voted for him on this occasion.
I conclude this section of the post with a picture of my Political Compass certificate (it is free and does not very long to answer the questions which are used to assign your score):
THE GAYWOOD LIBRARY EVENT
The event at Gaywood Library is a Business Eveningat which I hope it will be possible to raise the subject of the Autism Hour, one of the National Autistic Society’s recent initiatives. I have already confirmed that I will be in attendance. Here are a couple of pictures to end this section:
SOME NATURE PIECES
My nature links naturally divide into three segments, with a few photographs of my own forming a fourth. We will start with…
A NEW DINOSAUR FIND
This story courtesy of scienmag.com is about a dinosaur that has been named Albertavenator Curriei (“Currie’s Alberta Hunter”, named in honour of Canadian paleontologist Dr Philip J Currie). Below is a representation of this creature by Oliver Demuth:
A change.org petitionaimed at the sponsors of Arsenal Football Club asking them to withdraw support and so help force Kroenke out, screenshot below:
For ordinary Arsenal fans my suggestions are simple – boycott all home matches until Kroenke goes, and if you are a season ticket holder return your ticket and demand a full refund, making it clear that you will return if and only if Kroenke is no longer involved with the club.
MORE ON THE FIGHT TO PROTECT TROSA NATURE
This morning I reblogged Part 4 of Anna’s series of “Paradise on Earth” posts highlighting the wildlife that can be seen around Trosa and the Tureholm Peninsula. Since then she has added yet another post to that series, and I include links below:
Part 4, concentrating on birds including the Osprey shown below.
Part 5, also dedicated to birds. I have chosen as my sample image a Linnet.
Finally, to end this section, and the post as a whole we have some of…
