Can Turing’s Halting Problem Address Free Will vs Determinism?

My recent Decoded Science article, “Free Will, Determinism and Turing’s Halting Problem” helps explain Prof. Seth Lloyd’s insights into these issues.

A Quick Look at the Halting Problem and “Free Will vs Determinism”

Some scientists would argue that our brains are “simply” complex machines that make deterministic decisions, based on the physics and chemistry inside our skulls.

Yet we all have the feeling of enjoying free will, the ability to make decisions and also to change our minds of our own volition.

On the other hand, some people may sometimes appear to be trapped by fixed patterns of behaviour. Perhaps they do not have free will, if their decisions can always be predicted?

MIT prof. Seth Lloyd argues that deterministic decisions, whether made by computers or people, could still defy prediction and appear to be examples of free will.

Did Anyone Measure Science Comprehension in Canadian Politics?

Today Decoded Science published my “Interpreting One Report of Statistics on Science Comprehension“. A Yale professor had informally published a study that compared Tea Party supporters, conservative Republicans, and others in their test scores for science comprehension. My task was to explain what the professor’s statistics meant.

Has Anyone Studied Canadian Politicians for their Science Comprehension?

As a Canadian, simply researching that article made me wonder.

Has anyone tested our Canadian politicians for their skills, or attitudes, towards science?

My quick review of four federal party web sites revealed the following:

  • The governing Conservative party, which often has branded itself the “Harper government”, has no “search” function except to find members of parliament (MPs). I went through a few pages of news items, and did not find the word “science”.
  • Her Majesty’s Loyal Opposition, the New Democratic Party of Canada (NDP), put “science” in a news article from Sept. 2013. “NDP forces parliamentary committee to discuss challenges facing wireless telecom” simply names the title of one ministry, but at least they mention the word “science”. The NDP also lacks a “search” function.
  • The Liberal Party does provide a “search” function. Of several articles that used the word “science”, I noticed MP Marc Garneau’s 2011 post, “Where does science fit in with this government’s policy-making?“. Although Mr. Garneau may not be a rocket scientist, he is a retired astronaut, which counts as “pretty close” in my books.
  • Finally, the Green Party also supports “search”. Of several articles, may I note “Victoria: Rally for Science!” from 2012.

Let me admit that I have not pursued Canadian academic journals for statistical studies on our politicians’ views towards science, nor their comprehension of scientific principles.

Could you e-mail me a relevant link? I’d be more than happy to update this post, thank you, and share that link with our readers.

Refresher on Setting Your Long Run Pace

Distance runners must learn to set their long run pace so they can “stay the course”. My latest DeHaan Fitness article, “Discover Your Running Pace for the Long Run“, covers that topic with a bit of research and an explanation of how I re-discovered my own pace.

Find and then Improve on Your Sustainable Long Run Pace

As you run longer distances, your leg muscles begin adapting so you can stay on your feet longer and go farther. But you can still tire yourself out much too quickly, by running faster than your sustainable pace.

But of course you don’t want to “run lazy”; that doesn’t seem likely to give you the training benefits.

My article explains how to set your own long run pace; at least you should discover a slow pace that you can speed up as your stamina improves.

Autumn Road Races such as the 2013 Toronto Waterfront Marathon

This may be “just in time” for people training for the autumn road race season. The highly popular “2013 Scotiabank Toronto Waterfront Marathon” takes over Lakeshore Blvd (among other southern roads) on Sunday Oct. 20, 2013.

Non-runners can support charities by pledging for their favourite athletes in the Waterfront Marathon. They also need volunteers to help hand out water along the route (and many other small but vital tasks).

Ed Whitlock returns! I’ve written about him before, in “Triumph and Tragedy at the 2011 Scotiabank Toronto Waterfront Marathon“. To paraphrase the Jedi master Yoda, “When over 80 years old you are, run so fast you will not”.

It can be bought from the trusted suppliers who are viagra prescription authorized to sell generic and brand medical drugs. Every day a person in the world for super cheap cialis your lady. The elements are all levitra prices common and focused around old natural recuperating strategies. The route may change from year to year. I haven’t run the current route, so check their official Toronto Waterfront Marathon map before you plan where to watch. (I’d go to where King Street divides from Queen, just west of the Don River. Runners reach that location after 35Km of their 42Km race; then they go up and down Bayview for a few kilometres before resuming their run downtown. That’s about the distance where people begin to despair; they can see the downtown office towers that mark the finish, but that finish line is still out of reach).

The Toronto Waterfront Marathon is just one of many annual Toronto events that promote fitness and raise funds for charity. It truly is an autumn event, but the picture of the woman running past snow just reminds us that winter awaits.

Distance running serves as a great fitness technique. Part of the trick is learning to pace yourself. You can wear a running pace calculator in a sports watch; or simply trust what your body tells you as you run.
