Under the most rigorous of conditions they'll see whether they can find any evidence for the memory of water. We brought James Randi over from the United States to witness the experiment and we came to the world's most august scientific institution, the Royal Society. The Vice-President of the Society, Professor John Enderby, agreed to oversee the experiment for us...
The first stage is to prepare the homeopathic dilutions. We came to the laboratories of University College London where Professor Peter Mobbs agreed to produce them for us. He's going to make a homeopathic solution of histamine by repeatedly diluting one drop of solution into 99 drops of water...
For comparison we also need control tubes, tubes that have never had histamine in them. For these Peter starts with plain water...
This stage dilutes the solutions down to one in 100 - that's 1C. We now have 10 tubes. Half are just water diluted with more water, the control tubes, half are histamine diluted in water. These are all shaken, the crucial homeopathic step. Now he dilutes each of the tubes again, to 2C. Then to 3C, all the way to 5C...
Then we asked Professor of Electrical Engineering, Hugh Griffiths, to randomly relabel each of our 10 tubes. Now only he has the code for which tubes contain the homeopathic dilutions and which tubes contain water...
Next the time-consuming task of taking these solutions down to true homeopathic levels. UCL scientist Rachel Pearson takes each of the tubes and dilutes them down further - to 6C. That's one drop in 20 swimming pools. To 12C - a drop in the Atlantic. Then to 15C - one drop in all the world's oceans. The tubes have now been diluted one million million million million million times. Some are taken even further down, to 18C. Every tube, whether it contains histamine or water, goes through exactly the same procedure. To guard against any possibility of fraud, Professor Enderby himself recodes every single tube. The result is 40 tubes none of which should contain any molecules of histamine at all. Conventional science says they are all identical, but if Madeleine Ennis is right her methods should tell which ones contain the real homeopathic dilutions. Now we repeat Ennis's procedure. We take a drop of water from each of the tubes and add a sample of living human cells. Then it's time for Wayne Turnbull at Guys Hospital, to analyse the cells to see whether the homeopathic water has had any effect. He'll be using the most sophisticated system available: a flow cytometer...
But to be absolutely rigorous we asked a second scientist, Marian Macey at the Royal London Hospital, to perform the analysis in parallel. Our two labs get to work. Using a flow cytometer they measure how many of the cells are being activated by the different test solutions...
Now at last it's time to break the code. On hand to analyse the results is statistician Martin Bland...
The results are just what you'd expect by chance. A statistical analysis confirms it. The homeopathic water hasn't had any effect.
From the Horizon transcript.
Thanks for ferreting out these descriptions from the transcript. There is a problem with the preparation of both the homeopathic and control (water) solutions. I wonder if there is a reason the term "plain water" is used instead of distilled or preferably triple dstilled water. In addition was this plain water also used to make the homeopathic diutions? It would seem so. I see problems here.
Was this preparer experienced in this field? It would seem he has no special expertise in the area of preparaing homeopathic solutions as well as water solutions to be used as controls. Or perhaps the vagaries of the transcript which is NOT a scientific paper, is not peer reviewed and simply and inadequately describes the precise procedures and preparations employed.
Who can say?
Tai -- you are awarded two laughing dogs for your post....
