Happy 147th Birthday Canada!

happy_canada_dayHello all, and happy Canada Day to you! Today is the national holiday that marks the day that Confederation took place. For those not familiar, this historic event took place on July 1, 1867, when the three colonies of British North America came together to become the four provinces – Ontario, Quebec, Nova Scotia and New Brunswick – of the Dominion of Canada. Thereafter, July 1st became known as “Dominion Day” – until 1982 when the Canadian constitution was patriated, at which point it was renamed Canada Day.

Growing up in Ottawa – the nation’s capitol – Canada Day was always a special time. As a kid, it usually involved having a barbeque at home and proceeding to head downtown to see the crowds gather on Parliament Hill. At sundown, the fireworks display would begin, and we’d watch as from Major’s Hill Park (just across the canal from Parliament Hill) as thousands of them would go off above the clock tower (pictured above).

As I got older, the ritual remained the same, only it began to involve myself and my closest friends doing it instead. We’d start out at a friend’s house (more often than not, Luke would be the host). After some burgers or some other barbequed meal, washed down generously with beer or some other spirituous beverage, we’d proceed downtown. Once there, we’d get lost in the festivities, which would be pretty damn raucous and overwhelming!

jul-1st-canada-day-cityTo describe it, imagine 100,000 people crowded into the space of about 3 square kms. That’s where Parliament Hill, the downtown area, the Rideau Center, the old Bytown area, the War Memorial, the entrance to the Rideau Canal, and a slew of other major attractions are located. Vendors and buskers are out and about, people have their faces painted and sport flags, and the festive spirit just gets inside you and makes you want to party.

And of course, there is the televised concert taking place on the Hill, which features bands from all over Canada leading people in celebration. It was one of my fondest memories of living in Ottawa, and something I truly miss now that I live out here on the West Coast. Of course, Victoria puts on a might fine celebration as well, which has all the same high points. But since this is not the town I grew up in, it’s never quite had the same meaning for me.

So here’s to Canada, and here’s hoping that everybody out there has a day that holds special meaning to them too, and that they get to enjoy it this year without incident, stress or worry. And to all my American compatriots (including my sister and brother-in-law) happy soon-to-be Fourth of July!

Curiosity Rover’s First Martian Anniversary

Happy (Martian) Birthday Curiosity!

J. C. Conway's avatarJ. C. Conway

A Martian year is 687 Earth days long. Accordingly, NASA’s Curiosity Rover reaches its one-year Martian Anniversary on June 24, 2014 (Earth Calendar), 687 days after its mission began.

Curiosity has already accomplished the mission’s main goal of determining whether Mars once offered environmental conditions favorable for microbial life. One of Curiosity’s first major findings after landing on the Red Planet in August 2012 was an ancient riverbed at its landing site. Nearby, at an area known as Yellowknife Bay, the mission met its main goal of determining whether the Martian Gale Crater ever was habitable for simple life forms. The answer, a historic “yes,” came from two mudstone slabs that the rover sampled with its drill. Analysis of these samples revealed the site was once a lakebed with mild water, the essential elemental ingredients for life, and a type of chemical energy source used by some microbes on Earth. If…

Complications of the EPA’s Clean Power Plan

The latest effort to fight Climate Change from the US government, and how it may fall short…

Planet Earth Weekly's avatarPlanet Earth Weekly

Will the EPA do enough to make a difference? Five states have the top polluting coal plants int the U.S.

Are complicated politics going to fix our planet’s changing climate or is it time for each individual American to take responsibility for the growing problem?

By Linn Smith

June 18, 2014—-An article in the USA TODAY, June 9, 2014, titled, Retiring Coal Plants Won’t Do Much to Clean Air, caught my attention while sitting in the local cafe in a small town in the mid-west. Why? Because the proposed plants to be closed account for only 4% of all the CO2 emissions in the U.S. and “are mostly small, old generating units in the Midwest and South.” According to USA TODAY, the top polluting coal plants are located predominantly in five states. Texas has the most with 19, followed by Pennsylvania, West Virginia, Alabama and Georgia and the top 10% of these coal plants account for 69% of the…

The Nibble Approach to Asteroid Testing

Update on plans for possible asteroid mining!

J. C. Conway's avatarJ. C. Conway

NASA released this animation of a mission to capture a boulder from the surface of an asteroid. A NASA spacecraft, called an asteroid redirect vehicle, would use robotic arms to pluck a 3-meter boulder off the asteroid. The spacecraft would then enter a stable lunar orbit with the boulder where astronauts could then visit it and take samples. Take a look:

Elements4D – Exploring Chemistry with AR

Interesting and full of potential, I must say. As an educator, I look forward to the day when kids can even explore things at the cellular and atomic level using AR and VR.

Augmented Reality (AR) blurs the line between the physical and digital world. Using cues or triggers, apps and websites can “augment” the physical experience with digital content such as audio, video and simulations. There are many benefits to using AR in education such as giving students opportunities to interact with items in ways that spark inquiry, experimentation, and creativity. There are a quite a few apps and sites working on AR and its application in education.

Elements4D, an AR app from Daqri, allows students explore chemical elements in a fun way while learning about real-life chemistry. To get started, download Elements4D and print the cubes.

There are 6 physical paper cubes printed with different symbols from the periodic table. It takes a while to cut out and put together the cubes, but it…
