It has been three days since I last posted here, and five since I created anything new here. Just to keep things going here are some pictures that I have taken during that period.
The pictures I have from work that I consider worth sharing come in two sections. First…
FRONTISPIECES AND TITLE PAGES
We have some very old books going under the hammer in our auction at the end of November, and our printed catalogue will feature a page of some the finest frontispices and title pages, so here is a sneak preview:
My second set of work related pictures are of stamps, which were done yesterday using the scanner (400dpi, full platen being the setting used).
These are from a week ago – the moon in question was in a twilight sky.
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?
