If there’s interest, I’ll post more. Click and select “View full size” (below image, R) for full resolution. I lack formal training in geology, and would greatly appreciate comments on my proposed interpretations, but find structures such as these, on every scale, at once fascinating and beautiful.

Not all the news is bad; but strange times, when we have to welcome leadership from China.
Wandering Gaia is Gaia Vince, author of the award-winning Adventures in the Anthropocene, part of the emerging literature that welcomes the challenge of positively managing the planet.
If, like me, you wake everyday with a stone of foreboding in your belly, check the news to discover the world is a little worse, and stumble through your day under the heaviest pall of despair, then you’re not having the best 2017 either – I’m sorry.
Is this a new Dark Ages, this deliberate political, cultural, societal regression?
I’m sure there have been a thousand analyses of how we got into this darkly farcical horror show – and I mean the Trump presidency and Brexit disasters specifically, rather than the continuing awfulness happening to people Yemen, Syria, Nigeria, etc etc – but to be honest, one of my few comforts at the moment is my social bubble made up of kind, intelligent people who are also appalled by this new “post-fact”, mean era.
So what hope, can I give? And, yes, there is always hope!
Even though these recent…

Long but detailed; updated resources include rebuttals to creationist claims, including dinosaur soft tissue, and teaching exercise on Lucy. I have mined this for links. There is also a discussion of bible-basd arguments, for those (like the author) to whom such things are important.
By the early 1800s European geologists (many of them devout Christians) realized that the rock layers they observed had to be far older than the 6000 years allowed by a literal interpretation of Bible chronology. For instance, as discussed here , angular unconformities like that shown below could not been formed in the course of the one-year-long Flood of Noah.
Numerous other evidences for an old earth have been observed by scientists over the past two hundred years. These include fossil soils, and massive deposits of salt and of limestone in the midst of sedimentary rock layers, and tens of thousands of annual layers in lake bottom deposits (“varves”) and in glaciers (see Some Simple Evidences for an Old Earth). We can trace, in reasonable detail, the movements of the sections of earth’s crust over the…

Relative dating from sedimentology dates back some 200 years, as beautifully explained here by my friend, field geologist and Anglican priest, Michael Roberts, with illustrations from what he has seen himself, while we have now had absolute radiometric dates for over a century. Index fossils are used only to establish that rocks are the same age, and the way creationists manage to forget this fact is indeed miraculous.
This piece gains added interest because of its first-hand accounts, both of geological exploration, and of attempts to persuade creationists to accept the results.

Evolution is wrong as it is a circular argument from the age of fossils worked out from evolution
Yes, it is the old chestnut of Young Earthers that the age of rocks is based on a circular argument from evolution. It took me back to 1971 when I made the felicitous mistake of going to L’Abri to sit at the feet of the evangelical guru Francis Schaeffer. I arrived ther all bright-eyed and bushy tailed thinking of all the wondrous things I would learn in the next four weeks. I learnt much but not what I had expected.
On my first morning i was sent to Shaeffer’s son-in-law Udo Middlemann to discuss what I would study. I explained that I was going into the Anglican ministry and had just returned from 3 years working as an…

While NHS Scotland is devolved, immigration policy is reserved to Westminster.
In memory of his wife Nikki, who died two years ago come March of complicated leukaemia, despite expert care from a multinational team and international cooperation to find a suitable bone marrow donor, my son Geoff is launching this campaign, to enhance awareness of the massive contribution made by immigrants to health services throughout the UK, and without which the NHS would collapse.

The story so far: Spencer Fildes and I defended our petition to the Scottish Parliament’s Public Petitions Committee on November 24. The Committee (transcript here; see “New Petitions) listened most attentively, questioned us closely but not unsympathetically, and agreed to write to a number of organisations for their views. You will find full details, including petition text and links to the submissions received, at the Petition website. Now read on: Read the rest of this entry
I had the pleasure of hearing Abdus Salam give a talk in Oxford, sometime around 1960. I naïvely asked why a neutron would decay into a proton and electron, rather than an antiproton and positron, and he gently explained to me the concept of baryon number, which I would have known about by that point if I had been paying proper attention to his talk. Both prose and neutron have baryon (heavy particle) number +1, while their antiparticles have baryon number -1. They also have lepton (like particle) number 0, which is why the neutron decays into a proton, and electron, and an antineutrino.
The Washington Post recently ran a story about the late Abdus Salam, a physicist who won the Nobel Prize almost 40 years ago. The piece concerns the politics of naming a building at a Pakistani university in honour of a man from a religious minority background. Salam’s family belonged to the Ahmadiyya community – followers of a Muslim faith deemed heretical by Pakistan’s dominant Sunni Muslims. The religion was formally declared ‘non-Islamic’ by the Pakistani government in 1974. Before the new decree, extremists sometimes attacked and burned Ahmadi businesses, mosques and schools; after the decree, members could be imprisoned for their beliefs. In protest and for safety, Dr Salam moved to London.
Salam from Pakistan
Before leaving Pakistan, Salam had been the chief science advisor to Pakistan’s president, had contributed to theoretical and particle physics, was the founding director of the Space Research Commission (SUPARCO), and had…

Creationists argue that historical science is different from, and more uncertain than, present-day observational science. But their choice of examples shows that they themselves don’t really believe this.
The difference between what young earth creationists like to term “operational” or “observational” science and historical science doesn’t have the sharp distinction they like to project to their audience. I was reminded of this recently when I had an opportunity to hear Tommy Mitchell speak at a local Answers in Genesis conference a few weeks ago. One particular talk was entitled: Jurassic Prank: A Dinosaur Tale. In it Mitchell presents the young-earth case that dinosaurs lived with man as recently as a few thousand years ago. The “tale” of course is that scientists have been telling us that dinosaurs died out millions of years before man existed. You could say the punchline to the entire talk was that the public has been punked with regards to the truth about dinosaurs.
There are many lessons to be learned from this talk but I want to focus on one seemingly simple observation that Mitchell makes. Below is a YouTube version…
