Mike DeHaan began writing professionally in 2010 as the sole proprietor of DeHaan Services. Mike now blogs and writes freelance online articles under his own name. DeHaan Services provides ghost-written articles, web pages, business letters and a variety of other services, both locally and world-wide. Mike has trained himself to run marathons (each covers 26 miles and 385 yards, or 42.2Km), but now is usually content to help with a 10Km clinic at a local Running Room. Running and some attention to diet led to maintaining a weight loss of 20-30 pounds. He volunteers some of his time at the Mennonite church he attends.

A Home Lab Experiment with Table Salt and Water

I finally added a new Wizzley page today. “Air, Table Salt and Water in a Home Experiment about Mars” describes a very simple home lab experiment.

However, the article also presents a number of suggestions that can change a simple “proof of concept” experiment into a science project. How much extra work that would entail is entirely up to the experimenter!

You have to read the article to learn about the connection to Mars, the Red Planet.

In my Blog of Writing, “Preview of a Salt Experiment” both claims the copyright on my original images and also offers a writing tip at no additional expense.

The Toronto 2012 St. Patricks Day Parade Will March on March 11

Rather than be a day late, the 2012 St. Patrick’s Day Parade will march through Toronto streets on March 11, 2012.

Toronto’s St. Patrick’s Day Parade for 2012

The Toronto St. Patrick’s Day Parade parade benefits from publicity on the CP24 cable channel, but I never notice the important details because I’m so entertained by their leprechaun. For example, the 2012 parade will be held on March 11th, almost a week before the actual date of St. Patrick’s death and the Catholic saint’s day.

Details for the Toronto St. Patrick Parade

The important details for the St. Patrick’s Day Parade in Toronto include:

  • The St. Patrick’s Day parade will be held Sunday, March 11, 2012.
  • The parade starts at high noon, at the intersection of Bloor Street and St. George Street.
  • The route goes east on Bloor, south on Yonge, and east on Queen Street to Nathan Phillips Square in front of City Hall.
  • The parade should take about 90 minutes to pass by any one point.

The best way to get to the parade route will be public transit. The TTC delivers passengers by subway to the Museum station, St. George, Bay, Yonge & Bloor, Sherbourne, College, Dundas and Queen stations.

Anyone insisting on driving downtown should give the parade route a wide berth.

The St. Patrick’s Day Parade’s Grand Marshall’s Ball on March 10th

Those with $150/person who contact Lorraine Morley (via the web site provided below, in the “Reference” paragraph) before March 7th, may dine with the Grand Marshall, Eddie Thornton, at the Liberty Grand in Exhibition Place.

Dinner is at 6pm on Saturday, March 10th.

Who Organizes Toronto’s St. Patrick’s Day Parade?

The non-profit St. Patrick’s Parade Society of Toronto organizes this annual event.

Membership in this non-sectarian and non-political, non-profit organization is available to anyone for a small annual membership fee. The web site (below) provides an application form.

Disclaimer: I’m not a member of the society and not being paid to publicize the parade.


Refer to the society’s web site, “Toronto St. Patrick’s Day Parade“, for further details about the parade. Their site includes contact information for the Grand Marshall’s Ball; their membership application form; background about St. Patrick; Irish recipes; and contacts for Irish social organizations.

The web site names their current sponsors. To no-one’s surprise, Irish pubs and a brewery are represented. There are indeed other types of business as well, putting my thoughts of stereotypes to shame.

Those wishing to participate in, or sponsor, the 2013 Toronto St. Patrick’s Day Parade should also refer to their site for contact information.

Extra: One Place to Celebrate on the Actual St. Patrick’s Day

(Added March 10, 2012): Whether or not you miss the parade on March 11, Torontonicity reports that the “North Building of the St. Lawrence Market” will be open for St. Patrick’s Day festivities on Saturday March 17, 2012. Apparently there will be three time slots: 11am-2pm; 2pm-6pm; and 8pm until they throw out the stragglers.

Unless an Irish pub in Toronto advertises here via Google, you simply have my best wishes that you find your own way to celebrate your inner Irish spirit.

The Start and Continuation of a Turing Machine Series

My new series at Decoded Science begins with “A Brief Introduction to the Turing Machine“. Alan Turing’s invention was a huge contribution to pure mathematics, and is also a foundation for the computer (or hand-held web-enabled device) that you’re using at this very moment.

The Turing Machine and the Decision Problem

Alan Turing, along with Alonzo Church, put paid to one of the significant questions in early 20th century mathematics: could math itself decide whether any particular math theorem is true? The Church-Turing thesis demonstrated that the answer to the “Decision Problem” is: “no”.

Beyond using the Turing machine to resolve that question, Turing helped defend Britain in WWII by decoding encrypted messages and posthumously became a poster boy for the gay rights movement.

Further Articles in the Turing Machine Series

On Feb. 24th, Decoded Science published the second in the series. “Examples of Turing Machines: Loops, Halts, and Rewriting” provides three simple samples of Turing machines.

The third, “The Special Case of Non-Deterministic Turing Machines“, was published on Feb. 28th. Non-deterministic Turing machines take all possible computational paths simultaneously, which would be a neat trick for a real computer. It would be a neat trick to have a non-deterministic computer. Of course, “boffins” are working on it…

Publicity for the Turing Machine Series

The best publicity for this article is in my Blog of Writing, where “Preview of Examples of Turing Machines” includes a sneak peek at an image in the next article, plus the usual writing tip.
