Letting people know that I will be visiting Cornwall in the near future, and a few other bits and bobs.
My parents have recently moved to a place near Plymouth, and all they are currently out of the country travelling they will be back for a month or thereabouts from late October. I will be visiting their place in mid-November. I have asked for leave on the 9th and 10th of November so that I can go down on the 8th and come back on the 13th.
To get from King’s Lynn to Plymouth (nearest station to my parents’ new place) by public transport one needs to to travel from King’s Lynn to London King’s Cross, get a Hammersmith & City line train from King’s Cross to Paddington and then travel from Paddington to Plymouth (I already knew this). The journey takes in the region of six hours (I expected this to be the case but until I investigated did not know for certain). This why I requested leave for the two days concerned because the two days on which one travels are not going to be much use for anything else.
I discovered via www.thetrainline.com that tickets were available for £57. Thus I have made the booking and picked up the tickets.
COLLECTING THE TICKETS
Having made the booking I was assigned a code I could use to collect the tickets:
I decided that memorising an alphanumeric code of eight characters would be a bit of an ask even for me, so I called in at the library where I could screenshot the email containing the above, paste into paint and edit as appropriate before printing at a cost of 10p.
From there it was a short walk through the park to the station to pick up the tickets.
The email giving me the code to collect my tickets also included itineraries for both journeys.
This is a little stretched out, but I for one would not care to be on a train the was due to arrive at Kings Cross at 12:35 when I had to make a connection at Paddington at 13:05 – given British public transport’s usual “punctuality” that would be courting disaster.
The journey back could be a little quicker – but note that since there is no pre-booking on the London to Lynn line it is merely an annoyance should I miss the 14:44.
THE BRILLIANT.ORG 100-DAY
I recently received (by email) my certificate for having attempted all 100 of the problems (almost 50,000 people attempted at least one of these problems, of whom 1,797 attempted the whole lot).
Before moving on to the photographs that will conclude this post I offer you…
A PUZZLE OF MY OWN CREATION
Archaeologist and adventurer Idaho Johnson is near to making the biggest find of her life, but to do so she needs to get past the “Door of Death”:
Can you fill in the missing fourth vertical panel of numbers and get Ms Johnson through the “Door of Death”? As a bonus question can you identify the real door that I have used to create the above image?
A puzzle based on a blog post, a solution to an old puzzle, another puzzle from brilliant and some photographs
Earlier today I put up a post titled “About Autism“, and because that post contained so much stuff this post is going to be much smaller – and with only a few links, all in one way or another puzzle connected.
DERIVING A PUZZLE FROM A BLOG POST
Esterput up a post titled “Year 1729“, which featured the image below:
The puzzle I am attaching to this is: which two famous mathematicians are linked by the number 1,729 and how did that link come about?
If you can think of anything to help the Neurodivergent Rebel expand this list please use the quote out above, which if you click on it will open up an email message addressed to her which you can then complete.
The second piece concerns the make up of the Labour Party’s National Executive Committee – the detail contained in the title “EXCL: PRO-CORBYN ASLEF, FBU TO TAKE NEC SEATS” means that at least for the present, and for the very first time, the NEC will have a pro-Corbyn majority. Here is an ASLEF related picture:
The solution is 96% + 96% of 4%. 96% of 4 is (4 x 96)/100 = 3.84. 96 + 3.84 = 99.84, os the answer is that if the death rate in surviving species had been the same as the overall extinction rate then 99.84% of all living things would have died in that event.
For my next puzzle I turn once again to Brilliant and offer up the following:
Lionks to various pieces I have found on the internet, an answer and solution to one problem and a new problem, and some photographs.
This is a sharing post with some of my own stuff as well. I hope you enjoy it.
CROSSBOW BOLT STOPPED PLAY
Play between Surrey and Middlesex at the Oval has been halted and the ground has been locked down because a crossbow bolt was fired from outside the ground into the ground. Everyone at the ground is now in sheltered areas not out in the open. Armed police are now present at the ground. The match has now been officially abandoned, and a controlled evacuation of the ground is now underway.
I start with a tool created by the Labour Party called the living wage calculator. You enter your postcode and it tells you how many people in your area would benefit from the minimum wage being increased to £10 per hour. Below is what is says about my postcode:
In one of my posts on Monday I set a problem from brilliant. Here is I show the answer and an impressive solution. I also offer a new problem to end the section.
I admit to being lazy on this one – knowing that the internal angles of an octagon add up to 1080 degrees and that 7 x 90 = 630 I realised that with seven acute angles the remaining angle would have to be over 450 degrees, and the max is just under 360 degrees which takes you back to where you started. However 6 x 90 = 540 which means that the remaining two angles would have to add up to something in excess of 540 degrees, which is no great difficulty. Therefore I gave the correct answer of six (in less time than it has taken me to type this). However, one solver by the name of Atomsky Jahid produced a splendid effort:
A NEW PROBLEM
The mass extinction at the end of the Permian era is at the time of writing officially the largest in Earth’s history. An estimated 96% of all species on Earth at that time were rendered extinct. If the death rate in species that were not completely wiped out had been the same as the extinction rate what proportion of living creatures would have been wiped out in this event?
My next piece comes from Vox Political, who got direct from the person whose story it is, Paula Peters. The title of the piece “Bus driver subjects disability activist to humiliating discrimination” gives you a good idea of the nature of the story. British law on this matter is unequivocal – the bus driver is legally obliged to give wheelchair users priority over mothers with buggies (this courtesy of a court ruling in January). Given the completeness of the information Paula provides, the bus company in question have only one option open to them both legally and morally – they must sack the offending driver and must make sure that all their drivers are aware of their responsibilities to disabled passengers.
I started this post with a couple of science and nature related links, and now as we approach my photographs we are finishing where we started with stuff about nature, first of all Cindy Knoke with a wonderful post about a castle that has been dedicated to raptors, titled “Castle Rapture“.
With the last word before my photographs is Anna, who has recently posted part 13 of her amazing Paradise on Earth series, this time focussing on some of the smaller creatures who live in and around Trosa.
I will start this set of photographs with some of the smaller creatures I have recently captured, before finishing with some general pictures. These pictures were all taken yesterday.
Some stuff I have seen recently on the internet, a little teaser of a problem and some photographs from today’s ‘ecotherapy’ session.
I spent most of this morning indulging in ‘ecotherapy’ (i.e. getting out and about in the open air – my thanks to The Gentlemanfor the term), which also provide me with photographs which will end this post. In between times I will share various pieces that have caught my eye recently.
NATURE AND THE ENVIRONMENT
I start this section with a petition that has been set up on thepetitionsite calling for Michael Gove to be replaced as Defra minister (see graphic below, which also functions as a link):
GOVE is bad for the environment. Demand new Defra Minister!
It is pretty much impossible for any replacement to be worse than the Downright Dishonourable Mr Gove, although while this dreadful government remains in office the right person for the job will not be selected. In the hope that Jeremy Corbyn, or someone who can influence him might see this I say, as I did when naming my fantasy cabinet a while back that the right person for this role is Caroline Lucas.
This is the title of a piece in The Economist. After 120 years of dominating the scene the internal combustion engine’s days are numbered, and the end for this pollution generating monstrosity cannot come soon enough. I include their feature graphic below.
A PLAN TO REVIVE AN EXTINCT SPECIES
This one comes from thewildlifeplanet.com and the species that may be being brought back from extinction is the Caspiantiger. The plan involves using DNA from the Siberian tiger, a rare but surviving species that is closely related to the Caspian tiger. A potential living area for the revived species has been identified in Kazakhstan. The map below shows the areas reckoned to have been inhabited by the common ancestor of these tiger species when it was around 10,000 years ago.
I end this section of the post with a nod to Anna and the brief post she put up yesterdya about her continuing fight to protect nature under the title “I went to my church“, one picture from which I reproduce below. PUBLIC TRANSPORT
I am going to present these links as a bulleted list, amplifying some of them a little:
Our government has recently reneged on promised rail electrification programs in Wales and in northern England (yes, largely due to privatisation and consequent neglect our railways are so backward that not all of them have yet been electrified, some services still being run by diesel locomotives). Richard Murphy of Tax Research UK has put up a short post outlining how these electrifications could be funded.
The last piece in this section come from the skwawkbox. The first features a video from Double Down News which referring back to an incident from last year is utterly devastating for Virgin Trains, as it shows conclusively that Jeremy Corbyn was telling the truth when he described that train as ‘ram-packed’ and Virgin’s subseqnet denials, including one from the boss, Richard Branson, were lies. The most devastating footage comes about halfway through the video, which is embedded below, and shows the reserved seats filling (as one might expect) moments after Corbyn had walked past them. The skwawkbox piece is titled “DOUBLE DOWN VIDEO SCOOP PROVES WHAT WE TOLD YOU LAST YEAR: #TRAINGATE WAS FULL“.
Britain’s First Past the Post (FPTP) system of electing representatives has had its day. Those who support this system claim that it delivers stable majority governments, but it has failed to do this three times running (no majority in 2010, wafer-thin majority for Cameron in 2015, May running a minority government with the support of the vile DUP in 2017. I have three recent pieces dealing with this topic for your attention.
As well as the voting system needing reform, the results in Northern Ireland showed that it is time for the Labour Party to abandon its pact with the SDLP and field candidates of its own – the recent Stormont election successes of Gerry Carroll and Eamonn McCann have demonstrated that non-sectarian socialists standing as such can win in Northern Ireland.
A PROBLEM AND SOME PHOTOGRAPHS
I generally finish my posts by putting up some of my own photographs. Before getting to those I have a teaser for you:
The above table shows two putative sets of coin toss records, each for one coin tossed thirty times. Which is more like to be genuine based on what you can see?
a) series one
b) series two
If you want to have a public stab at answering this feel free to use the comments, although I will say neither yea nor nay until I put my next post up, which will include an answer to this little teaser.
The answer to a problem incliuded in yesterday’s post Monday Miscellany.
You may remember that in yesterday’s post titled “Monday Miscellany” I included one of the problems I had solvced on the mathematical website Brilliant – this post presents the solution and also clears up a side issue raised on that website by disgruntled folk who had got it wrong.
Here is the problem again from yesterday:
The answer is True. The formula for (x+1)^2 is X^2 + 2X + 1, and every odd number greater than 1 could serve as the 2X+1 part of that equation.
THE SIDE ISSUE
Some people on Brilliant cavilled at this because there are some Primitive Pythagorean Triples whose smallest term is even (8,15, 17, 20,21,29 and 65,72,97 were all mentioned, although none of the complainers mentioned 12,35,37, 60,91,109 or 696,697,985). The question did not state that the triple of which the odd number is the lowest term was the lowest triple to feature that number, and indeed if one looks carefully at the triangles presented as part of the problem one can see clearly that the odd number is allowed to be in another triple where it is not the lowest term:
Note that the number 5 features twice (ringed in the diagram above, once as the largest term in a triple and once as the smallest).
Thus that 15 features in 8,15,17 does not invalidate the claim of the question since it is the smallest term in 15, 112, 113. All the other odd numbers mentioned in triples of which they are not the smallest member likewise feature in triples in which they are the smallest member, the biggest being 985, 485112, 485113.
