New video blog

Posted on May 17, 2010 at 9:32 pm

I’ve been listening to the Skeptoid podcast for a long time now, and I’ve been a big fan. Well now you can get your skeptical video fix, too. A sibling vodcast called inFactVideo is available. I’ve watched the first few and it is now in my regular list of downloads. Have a look and see what you think.

What if – Homeopathy Worked?

Posted on April 18, 2010 at 9:53 pm

There have been several articles written showing that homeopathy has no measurable effects. There have also been articles written showing the absurdity of homeopathy. This article is going to be different. We’re going to look at homeopathy and grant the proponents the benefit of a doubt. We will assume that everything reportedly claimed about homeopathy and its effects is true. Using that as our basis, where do we end up?

Let’s start with a refresher on what exactly homeopathy is. Homeopathy operates on the principle that as a solution gets more dilute, its effects on biological systems increases. So the strength of a homeopathic remedy is a measure of its relative dilution. All of the measures are made using orders of 10. So a dilution of 1X is a 1 in 10 dilution. A dilution of 2X would be a 1 in 10 dilution of a 1 in 10 dilution, or a 1 in 100 dilution. A dilution of 3X would therefore be a 1 in 1000 dilution, and so on and so on.

One of the mechanisms cited quite often for how homeopathy works is that water molecules have some form of memory, and that the water solvent somehow remembers the chemical compounds that it has come in contact with. We won’t, for the moment, concerns ourselves with the how. For now, we will simply accept that this is true. What does this mean?

The very first concern should be, how do we get uncontaminated water to make our remedies with? If water remembers all of the chemicals that it has been in contact with, then any liquid water is, by this definition, contaminated by untold numbers of chemicals. No matter its source. Water from the tap will be contaminated by having come in contact with all sorts of metals and plastics from all of the pipes and machinery through which it needs to travel to get to your kitchen. It is also exposed to toxic chemicals used to kill off any potential pathogens. Water from the sea has been exposed to almost every man-made and naturally occurring chemical in existence. Spring water is exposed to salts, metals and micro-organisms in the soil. Basically, liquid water is completely unusable. This means that we need a source of non-liquid water, for example, water that has been distilled.

Some homeopathists will say that this is unnecessary. They may say that the initial solution is concentrated enough to essentially swamp out any residual memory in the water from earlier chemicals. If this is true, then this would only apply to the first few dilutions. Once the remedy has been diluted enough times, then it will have the same approximate strength as the residuals in the water being used. So it will be competing with all of the chemicals from the water’s history to make itself felt. This is not a solution to the problem. The only logical solution is to use pure distilled water for every step of the preparation to ensure that the patient only receives the necessary remedy and not exposure to untold numbers of other chemicals. So the first question to ask your homeopathist is “Do you use distilled water?”

Still on the topic of making the dilutions, what happens to the waste from the intermediate steps? It is impossible to manage all of the water required without disposal of some of it. As an example, if you wanted to make a 100X dilution, starting with 1oz and not disposing of any intermediate steps, you would require 10 to the power of 100 ounces of water, or….
Since these homeopathic remedies have real, physical effects (remember we are assuming all of the claims are true) then it would be irresponsible and unethical to simply dump the intermediate steps down the drain. Doing so would effectively contaminate every drop of water that comes into contact with this waste. Again, if the memory effect is a quality of the liquid state of water, then the only ethical thing to do is to distil the water before disposing of it. This would effectively destroy any memory stored in the water. So the next question to ask your homeopathist is “Do you safely and ethically dispose of your wastes?”

A competing theory of how homeopathy works states that the memory of water is something that needs to be activated through intention. That is, when dilutions are are being mixed, a person needs to do it and apply their intention to the process in order to imprint the memory onto the water. If we assume that this is true, then it does remove our first concern about the source of the water, since we would effectively be “reformatting” the water during the imprinting process. But we are still left with the issue of ethical disposal of waste products, since even a single drop of homeopathic remedies is reputed to be effective. So the practitioner still has a responsibility to safely and ethically dispose of any waste products.

But if this process of intentionally imprinting the memory of the chemical into the water is correct, then homeopaths, as healthcare providers, have a moral obligation to shut down over the counter homeopathic remedies. By their definition, these over the counter remedies are bogus, since they are done in a factory by machines. There is no person involved providing the intentionality needed to imprint the memory onto the water. So, ethically, homeopaths need to start petitioning government to ban these quack remedies. To do less would be immoral. So another question to ask your homeopath is “Do you believe intention is important, and if so, what have you done to remove quack remedies off of store shelves?” I expect my healthcare providers to be highly ethical.

Two new columns

Posted on March 8, 2010 at 5:06 pm

Well, I’ve had several ideas mulling around in my head, and I think they’ve reached the point where I’m ready to start actually working on them. I’ve had two ideas for regular articles: a “What if?” column, and a column of “Maple for Mythbusters”. The first column will be articles where I look at different ideas and say “What if this idea were real? What would it mean?” The first one is going to look at homeopathy, and make the assumption that it is real. Starting there, what else do we have to accept, by logic, due to accepting that homeopathy is real. I’m going to look at a different idea for each article. The second column is going to look at different experiments that the Mythbusters have done and see how we can use Maple to do some scientific computations around those experiments. I really like Maple, and I think more people should be supporting a Canadian made product.

These two columns are going to run on alternate weeks, starting with “What if?” this Friday. If you have any ideas for either column, things you’d like to see covered, please let me know.

Now I know what to do in my basement…

I so wish I had some spare money and time. Course with my luck, I’d actually get over-unity and blow up my house.

The EPR Paradox

Posted on November 20, 2009 at 11:51 pm

The physics department just had a talk by a researcher from Wilfred Laurier University, discussing the EPR (Einstein-Podolsky-Rosen) Paradox. This is a very counter-intuitive quantum effect which is very difficult to describe. The speaker this afternoon did an excellent job of describing it in regular language. I was very impressed. It really is true, you can only really explain something to someone else once you fully understand it yourself.

In short, Einstein, Podolsky and Rosen were bothered by the weirder conclusion from quantum mechanics. So they proposed an experiment that you could do which would show that the quantum model was incomplete. Unfortunately for them, the counter-intuitive results of the experiment actually did occur, proving that quantum mechanics actually is correct. This experiment was the beginning of quantum entanglement, and all of the wonderful weirdness which grew out of that.

I just saw this site this morning. I found the link in Make magazine (awesome magazine, by the way). There is far too much info here for me to go into. All I can say is that you need to go check this out if you have any interest in physics or science.

Perma-tech

Posted on May 18, 2009 at 10:35 pm

You’ve likely heard of permaculture before. This is the philosophy of agriculture which is capable of being permanent. The idea is that you plant your crops and care for your soil so that it can be sustained indefinitely. I think that it is time for us to start thinking the same way about our technology. A kind of permatech.

The beginnings of a movement are starting to form. An example is the repair manifesto. The idea here is that we should look at the items that we purchase and use in our day-to-day life, and choose items that can be repaired. If an item cannot be repaired, we are effectively just renting the item. When it finally does break, or wear out, we have no choice but to dump it in the trash and get a new one. The manifesto itself is:

  1. Make your products live longer!
    Repairing means taking the opportunity to give your product a second life. Don’t ditch it, stitch it! Don’t end it, mend it! Repairing is not anti-consumption. It is anti- needlessly throwing things away.
  2. Things should be designed so that they can be repaired.
    Product designers: Make your products repairable. Share clear, understandable information about DIY repairs. Consumers: Buy things you know can be repaired, or else find out why they don’t exist. Be critical and inquisitive.
  3. Repair is not replacement.
    Replacement is throwing away the broken bit. This is NOT the kind of repair that we’re talking about.
  4. What doesn’t kill it makes it stronger.
    Every time we repair something, we add to its potential, its history, its soul and its inherent beauty.
  5. Repairing is a creative challenge.
    Making repairs is good for the imagination. Using new techniques, tools and materials ushers in possibility rather than dead ends.
  6. Repair survives fashion.
    Repair is not about styling or trends. There are no due-dates for repairable items.
  7. To repair is to discover.
    As you fix objects, you’ll learn amazing things about how they actually work. Or don’t work.
  8. Repair – even in good times!
    If you think this manifesto has to do with the recession, forget it. This isn’t about money, it’s about a mentality.
  9. Repaired things are unique.
    Even fakes become originals when you repair them.
  10. Repairing is about independence.
    Don’t be a slave to technology – be its master. If it’s broken, fix it and make it better. And if you’re a master, empower others.
  11. You can repair anything, even a plastic bag.
    But we’d recommend getting a bag that will last longer, and then repairing it if necessary.

Stop Recycling. Start Repairing. www.platform21.nl

Instead of buying the cheapest item, I think that we need to start thinking about the actual quality of the items we are purchasing. And we also need to start thinking about the total value of an item. This includes its aesthetic value. Objects should look good, feel good, be sturdy, and be capable of being repaired. If they worked well, we would actually use the item. If it looked good, we would likely take better care of it, and feel good about having it. If it was easy to repair, we would feel more investment in it.

Atlantic general relativity mini-conference

Posted on May 12, 2008 at 9:48 am

This past weekend was really fun.  The math department here at UNB held a mini-conference on general relativity.  The one talk that really got my juices flowing was one on stochastic gravity.  This formulation seems to allow for a bottom up way of tying quantum fields to the metric.  I’m going to use this with a field description of the electron and see what I find.
