I’m a controversialist and catalyst, quietly enabling others to develop by providing different ideas and views of the world. Born in London in the early 1950s and initially trained as a research chemist I retired as a senior project manager after 35 years in the IT industry. Retirement is about community give-back and finding some equilibrium. Founder and Honorary Secretary of the Anthony Powell Society. Chairman of my GP's patient group.

Thinking Thursday #6

Here begin the problems to sharpen the young is the beginning of a wonderful text which it is believed was written by the Carolingian scholar Alcuin of York (c.735–804). The work presents over fifty mathematical puzzles many of which remain a challenge even for modern readers. Here is one of the best known, which you may well have come across before:

A man has to take a wolf, a goat and a bunch of cabbages across a river. The only boat available can accommodate just two of them at a time. It is well known that if left alone together the goat would eat the cabbages, and the wolf would eat the goat; but the man has been ordered to transfer all of them to the other side dry and in good condition. How can he achieve this?

As always there’s no prize other than the satisfaction of solving the puzzle — but do feel free to show off by putting your answer in the comments.
Answer on Sunday evening, as usual.
Oh, and no cheating!

Oddity of the Week: Not Taxidermy

Should you be of a mind, it is quite easy to buy examples of taxidermy: just go to a few local auctions and you’ll soon find all manner of creatures in glass cases.
But you can now go one better: Upholstered Faux Taxidermy Heads and Animals.

American artist Kelly Rene Jelinek fabricates life-sized replicas of taxidermied animal heads using fragments of upholstery fabric. The results are surprisingly modern sculptural objects that mimic traditional anatomical mounts.

Your Interesting Links

Another of our monthly round-ups of links to items you may have not wanted to miss the first time round.
Science & Medicine
The Black Death, a strain of bubonic plague, wiped out an estimated 50 million people in Europe during the 14th century. But it didn’t then disappear.
Ever wondered how scientists choose those awful Latin names for species? Here’s the low-down.


We know cats are odd creatures, but apparently cats’ legs are extra weird.
Manx cats have no tail. It’s genetic, see, but that brings other problems along with it.
And yet more on cats … here are a dozen cat myths debunked.
Scientists and medics are beginning to discover (realise?) that our circadian rhythms affect the way drugs work.
Finally in this section, here’s an interview with one of our top science writers, Ed Yong, on being a science journalist.
Sexuality
Sex educator Emily Nagoski (author of Come As You Are) gave a TEDx talk on “Unlocking the Door to Your Authentic Sexual Wellbeing”. Here’s the video, and transcript.
Seems we’re too busy these days to have sex, but two minutes sexual arousal for its own sake can help a lot — apparently.
Environment
Beavers. It seems the ones in Devon are helping fight floods as well as improving the environment.

There’s been a lot of work in recent years on the intelligence of corvids. Now it seems corvids are the key to saving the world’s forests too.
Social Sciences & Business
Parenting — we all know it is tough work. But here are two articles, both from the Guardian, which might help. First “How to raise a brilliant child without screwing them up” and on a similar theme “How to get your kids to 18, sane and not hating you“.
Some thoughts on why we don’t live in a perfectly nude world?
History
Archaeologists are beginning to piece together the lost town of Dunwich which has progressively been reclaimed by the sea over the last 1000 years.
And now for several items on London’s history …
Firstly on the dissolution of London’s monasteries.
And on the two great 17th century diarists, Samuel Pepys and John Evelyn.
In his series on “Unbuilt London” IanVisits looks at the proposed Georgian Houses of Parliament.
There are lots of monsters in London, but they aren’t all scary.

Food & Drink
Why is it that some things we find tasty other cultures find disgusting, and vice versa?
Shock, Horror, Humour
And finally, IanVisits provides an entirely level-headed and rather interesting discourse on the EU referendum without coming down on one side or the other.
Another round next month.

Weekly Photograph

Apologies for the hiatus last week, I got buried in various pieces of urgent work.
This week we delve once more into the archives. This is from one of our 2010 visit to Rye and environs. It is a detail from the garden at Prospect Cottage, the late Derek Jarman’s home at Dungeness. The stone circle is probably just under 3 feet across.

Those Alcohol Guidelines, Again

Under the title No wonder Britain’s alcohol guidelines are so extreme — just look at who drafted them Christopher Snowdon at Spectator Health lifts the lid on the way in which the new alcohol guidelines were arrived at.
If true, and I have no reason to suspect Snowdon isn’t being truthful, this is a disgraceful abuse of power by the Chief Medical Officer, and others, to arrive at conclusions which suit their personal predilections in the face of major conflicting evidence.
Given the academic stature of many of those involved, they really should know better. The fact that they appear not to, should be sufficient to disqualify them from their roles and they deserve to be summarily sacked.

RoboLit

There was a brilliant piece in last Monday’s Guardian in which Stephen Moss asks what robots might learn from our literature. I give you a sample:
[A] new generation of robots combining artificial intelligence with great physical power may not … wipe us out after all. We can be friends, united in a common appreciation of Middlemarch. But a less sunny outlook is suggested by … the Shepton Mallet School of Advanced Hermeneutics [who] fed the entire world’s literature into a robot (called HOMER16) fitted with a high-powered computer; preliminary results are worrying.
Here are some extracts from the HOMER16’s initial readings.
Hamlet: Dithering prince with unhinged girlfriend demonstrates how dangerous it is not to act decisively. Interminable and convoluted plot obstructs the central message that your enemies should be dispatched quickly, brutally and mercilessly. Cannot compute the meaning of the strange “To be or not to be” speech. In what sense is that the question?
A Clockwork Orange: Frightening study that shows the extent to which a love of classical music can damage the human brain. The works of Beethoven seem to be especially dangerous. Fail to understand why this material is still played, even on radio stations that very few people listen to.
The New Testament: Ludicrous set of stories in which the sick are miraculously healed, fishes and loaves materialise from nowhere, and a young man comes back to life after being executed. The telling by four narrators is interestingly postmodern, but the plot is too ludicrous to hold the attention. Could not compute the long introduction called The Old Testament, which seemed very dull and repetitious.
À la Recherche du Temps Perdu: A book in need of an editor about a protagonist in need of a psychiatrist. Good on the dangerous consequences of eating cake.

Oddity of the Week: Egyptian Pigments

William Perkin is credited with with making the first synthetic organic dye (using chemists’ meaning of organic, ie. carbon-based molecules) when he accidentally discovered aniline purple, aka. mauveine, in 1856 while trying to make quinine. (Incidentally Perkin set up his factory to manufacture mauveine on the banks of the Grand Union Canal just half a mile from my home in Greenford.)
However Perkin was probably beaten to the first organic synthetic dye by the Egyptians, possibly as early as 3000BC. By heating a mixture of sand, ash, calcium carbonate (from shells?) and a copper ore to temperatures of over 800°C they manufactured blue calcium copper silicate, otherwise known as Egyptian Blue. This was then used in glazes to produce a stunning range of hues — as in this votive cup with cartouche of Amenhotep III (c.1391–1350BC).


There’s more on modern chemistry firsts which were known in ancient times including chromium plating, concrete and nanotubes.
