I note that the ECG website
http://edinburghcreationgroup.org/
continues to advertise Professor Andy McIntosh's claim that:
"Rain is impossible".
PROFESSOR McINTOSH: "My knowledge of thermodynamics has shown me that all mechanical systems (such as an engine or fridge or aeroplane etc.) require not only energy but ordered machinery in order to work. Thus simply adding energy to a lump of matter will not turn this into a machine which can do useful work."
The Earth is a "Lump of matter" to which energy is added in the form of radiation from the sun. Water evaporates from the oceans, and the wind blows the clouds over my garden where it is precipitated as rain which waters my lawns. Consequently, the Earth operates in a thermodynamic cycle and performs this very useful work.
Coincidentally, Professor Peter Atkins (Author of a book on the laws of thermodynamics called "Four Laws that drive the Universe") is presenting a talk at the Science Festival next Thursday ( 20:00 27th March Museum of Scotland).
I have asked the Edinburght Creation Group the following question:
If you or any of you colleagues can make any kind of a case that supports the notion that "Rain is impossible" we might have an opportunity to put that to Professor Atkins to see what he makes of it.
I await there response. :-)

Hi SG,
On Tuesday evening Paul James-Griffiths a former lecturer in ancient history will present a lecture on the Easter story 7:30pm Baccleuch Free Church
PAUL: Is Darwin's Theory of Evolution Unfounded?
PAUL: There is .a lot of confusion over this subject.
PAUL: I would like to make it clear that all the Creationists I know accept natural selection and adaptation as scientific facts (microevolution)
PAUL: however, many reject the idea that variation within each kind of creature is sufficient to suggest the common descent of all kinds of creatures from a single celled organism (macroevolution).
PAUL: To go from one to the other is a huge leap of faith even at the molecular level; the evidence is simply not there.
There are several problems with the evolutionary idea of the origin of life and its development, which a growing number of agnostics also realise. Briefly summed here are a few of these problems:
PAUL: 1. The Law of Probability: even the probability of a single average globular protein appearing by chance is about 1 in 10^130. That is a figure larger than the
number of atoms in the history of the cosmos. And we have not even looked at the rest of the evolution package. More recently scientists have calculated the probability of the simplest genome emerging through random trials as 1 in 10^80,000. Mathematicians generally regard 1 in 10^45 as being the upper limit of sensible random processes.
PAUL : 2. The Law of Biogenesis: nobody has ever contradicted this law and demonstrated that life can come from non-life.
PAUL: Any successful attempts would involve intelligence.
PAUL: 3. The Law of Thermodynamics: everything on the planet is subject to decay, which works in opposition to evolution.
PAUL:3. Even open systems only work if there is existing machinery in place, such as proteins that control cellular function.
PAUL: 4. Information: all known codes are evidence of an intelligence, this should, if we are unbiased, include the DNA.
PAUL: 5. Heredity: In every experiment thus far when we have tried to demonstrate macroevolution,whetherwithDrosophila, E.Coli, or anything else, we have always found a fixed boundary beyond which the road leads only to dead ends or the lethal degeneration of a species.
PAUL: 6. Stasis in the Fossil Record: 40-80% of living forms today are represented in the fossil record, despite being told in many text books that only about 0.1% are in this category. The rocks testify that no macro-evolutionary change has ever occurred. With the Cambrian Explosion complex fish, trilobites and other creatures appear suddenly without any precursors. Evidence of any transitional forms in the fossil record is highly contentious.

Hi SG,
"I have a mental picture of Andy looking around with that "help me someone " look on his face! "
Yes, he did just that :-)
"This Edinburgh Creation Group intrigues me. Edinburgh of all places, the birthplace of the Enlightenment, the Athens of the North.... "
The Creationists seem to be making a concerted effort in Edinburgh at the moment. Famous speakers and meetings ever Tuseday night in a church next to the University.
I also had an encounter with famous Australian Creationist John MacKay.
http://www.amen.org.uk/cr/who/index.htm
Like Andy, John is a very entertaining speaker - not right - but very entertaining. He mounted a concerted attack on Darwin ( The ad hominem fallacy) and his theory (misrepresentation of science).
Part of his presentation was concerned with the high level of correlation between Human DNA and Chimp DNA. He was ridiculing the way in which the alledged level of commonality reported by scientists has come down from 98% to 95%. He then went on to show (at some length) that small changes in coded information can result in large changes in the meaning of the information. He showed numerous examples of English sentences in which small changes in letter order or single character substitutions can completely change the message. Sometimes hilariously.
This seemed to be a concerted attempt to "muddy the water" regarding our genetic relationship with our nearest relative and imply that evolutionists were trying to argue that that small numerical differences in DNA comparisons didn't really matter. The point is that the 90% commonality is powerful evidence of common ancestry. John didn't mention that so I pointed it out.
I also said that development biologists now understand in considerable detail how genetic information is used as organisms develop and they would agree that very small changes can have a dramatic effect. I then added an example of my own that didn't involve any letter re-ordering or substutions. It involves only the addition of a space. I said:
"Genesis isn't the answer - Genes is."
At that the audidence laughed and John's body language signalled a level of discomfort.
It was great fun and very rewarding to be able to stop a very acomplished nonsense spouting Creationist in his tracks by beating him at his own silly word game.
I strongly recommend the process. :-)

Professor Andy McIntosh "proves" that vaccination cannot work and that rain is impossible:
Last week I went to a presentation given by Professor Andy McIntosh to the Edinburgh Creation Group.
Andy is an engaging and charismatic speaker and very likeable. It's almost easy to forgive him for being so profoundly wrong....but only almost :-) We saw a Science Professor at a British University using his position of responsibility and authority to claim that science supported his creationist stance where, in effect, he claims:
1) Rain is impossible. ( Expressed as :"Just adding energy to a lump of matter cannot turn it into a machine".)
2) Information cannot be added to DNA
3) Therefore Evolution is impossible.
I thought it polite to wait and give the other people in the audience a chance to ask questions but nobody did in the first 15mS so I slowly raised my hand. I complemented Andy on the entertainment value of his talk adding that I had "A million questions". The chairman looked relieved when I said that I would ask just two of them.
Q1) If information cannot be added to DNA then how does our immune system deliver immunity from disease following vaccination?
Q2) The Earth is a lump of matter and energy is added from the sun. This seems to result in a "machine" that waters my lawn.
Why do you claim that such a machine is impossible?
Prof Andy listened carefully to my questions without any noticible body language. He then started waffling and repeated some of his previous claims. I kept interrupting to bring him back to my questions. He had spent over an hour talking about biochemistry from his platform as a Professor at Leeds University. He finally realised that his waffles were not going to answer my question so he explained that he "wasn't an expert in this area" and asked me to explain how the immune response to infection worked.
This I duly delivered.
Andy's response to this was amusing. There was some evidence that he had never been asked this question before and he waffled around looking for an angle. He then got some support from a biologist in the audience who explained about the gene-recombination phase of antibody maturation. I agreed with that but explained that this was followed by the Hypermutation phase wherein random mutations to DNA are naturally selected to enhance the binding affinity . The resulting "information enhanced" DNA is retained for use on future occasions should the antigen re-appear. Without this addition and retention of information enhanced DNA, our immune response to infection would be far less effective and our vaccines would fail to protect us from disease.
Andy seemed not to be following this and he tried "Junk DNA" saying that scientists had got it wrong because it wasn't "Junk" after all and it could "Learn". I pointed out that "learning" involves the acquisition and storage of information - the very process that he was claiming was impossible because of thermodynamic considerstions. So he changed tack. He tried to argue that the immune response only worked because it is an "existing machine". I agreed with that pointing out that machines can arise naturally. Andy insisted that they cannot because they are prohibited by the laws of Thermodynamics - his specialist subject.
I then reminded him of my second question about the lawn watering machine explaining that when the sun heats the earth it operates in a thermodynamic cycle and that makes it a machine. If naturally arising machines are impossible then rain is also impossible. At that, Andy's eyes exhibited a slight glassiness as he searched for a new waffle angle. This seemed to indicate a sudden realisation of an interesting consequence of his claim that he hadn't paid sufficient attention to.
I foud it rather surprising to have to explain "rain" to a Professor of Thermodynamics from Leeds University.
However, having established that machines like the Earth's thermodynamic cycle can arise naturally and that information can indeed be added to DNA as part of the human immune system's response to infection, I set out to challenge Andy's position on the possibilities that lay between these to extremes. The regime that is the province of the theory of biological evolution. Andy changed the subject and started talking about electronics and poor old Payley's watch and the significance of free energy states to life and the inability of non-living matter to make use of that.
My response was that computers and watches do not meet Darwin's pre-conditions for evolution to occur. Andy signalled that he wasn't at all sure what Darwin's pre-conditions were and argued strongly that they shouldn't be brought into his purely thermodynamic argument. I pointed out that it would be very difficult to discuss Darwinian evolution if we excluded the principles of Darwinian evolution, as encapsulated in the three pre-conditions, from the conversations. Andy conceded that was so and asked me to explain what the pre-conditions were. This I duly did:
1) Descent - Parents have offspring
2) Heritable random variation
3) Cumulative natural Selection.
"Ah!" exclaimed Andy, "You have got to be very careful when you bring things like that into the argument". I said "OK let's do it carefully" pointing out that the pre-conditions do not violate any of the laws of Thermodynamics and that computers and watches didn't get pregnant and give birth to babies of their own knid. . Andy then insisted that they did violate thermodynamic laws and indicated that he promotes the classical misconception about thermodynamics and "Order". Thankfully, the Americian association of Chemistry Teachers is running a concerted internet campaign to get this sorted out. King Tut's tomb lay exactly as it was left for 4000 years until Carter opened it. That was because it was in thermodynamic equlibrium with its surrounding. There was no "natural tendency towards disorder" that notion is a pernicious fallacy.
How is it possible that a Professor of Thermodynamics doesn't know that?
Why did I have to explain how the "birds and the bees" differ from watches and computers?
How is it possible that a University Professor uses his position of authority and responsibility to promote gross misrepresentations of his own specialist area and many other important areas of well established scientific knowledge?
This is not about religious belief or faith. It is about science and the "science" that Professor McIntosh preaches at these meeting is patently, obviously and disastrously in error.
Is Leeds University aware of how badly this reflects on their "Centre of Excellence"?
