Ion Propulsion - The Next Generation

For all you "trekkies" or "trekkers" here is more evidence that Star Trek has changed the world.  A space probe called Dawn is travelling beyond the orbit of Mars and heading into the asteroid belt between Mars and Jupiter. Dawn is supposed to achieve "standard orbit" (a Star Trek term - see picture) around the asteroid Vesta, staying and exploring a while then heading off to the asteroid Ceres later. These are two of the largest asteroids in this solar system. Why study asteroids? Well, the standard NASA answer is to gets some insights into how they formed and help scientists understand the formation of the solar system. Of course asteroids may be cholk-full of raw materials, so science may not be the only reason for such a trip.
This is not the first time asteroids or comets have been visited. On July 4th, 2005, NASA's Deep Impact probe intentionally collided with the comet Temple 1. In January 2006, NASA's Stardust probe returned samples of the Comet Wild and is on route to visit Temple 1 in 2011. In September 2008 the European Space Agency's Rosetta probe flew by the asteroid Steins.
But the Dawn visit is unique because it orbits two asteroids and if it had used conventional fuel it would have been too heavy to launch with current vehicles. Instead of conventional fuel Dawn uses Ion propulsion, a concept made popular during the original Star Trek series.  This clip helps explain:

Vote small, think big - can't agree more!

Pat Condell is one of my favourites. He is British and speaks from the European perspective and his message is mostly anti-religious. That gets a bit tiresome sometimes, but he does such a good job of it, and his delivery is so smooth, that just to watch him is a pleasure. Maybe it's just because of his accent, he sounds so smart - I think he is.
Thursday, May 6th is the British election, an important one not just for the Brits but all of Europe and even us to some extent. In a recent post he spoke about the importance of this election. Condell is no libertarian, but his message is one that should be heard because it can be applied in Canada or the US. Have a listen:

GM (Government Motors) loan pay back explained

Remember "new math"? Neither do I, but I do know when I'm being scammed. The CEO's of GM in the USA and Canada are bragging about their loan repayment in contrived television ads being played in both countries. They are STRETCHING THE TRUTH, and if they can lie without consequences we're all screwed. Here is another more accurate representation of the lie:

Canadian electoral reform

This week in the Globe & Mail Neil Reynolds writes about Canada's inability to elect majority governments of late, and how that could jeopardize our democracy.
Well, I won't start rhyming off the jokes about democracy and the tyranny of the "majority" and how democracy is three wolves and two sheep voting on what's for dinner.......OK, sorry, I said I won't.
Mr. Reynolds makes the point that very few (25 out of 308) of our Federal Members of Parliament (MPs) actually received a majority in their ridings in the 2008 federal election. That fact can be viewed this way: only 59% of the qualified electorate actually voted and 37% of them actually chose candidates that form our current Conservative minority government. So our current government represents just 22% of the possible voters, but that speaks to the issue that voters feel powerless to change the system so they don't bother to vote. That last point of course, is why we have many little parties, Libertarians among them.
Mr. Reynolds suggests that allowing a "runoff election" in ridings where no candidate has a majority, as is done in many countries, will rectify the situation. He further goes on to blame our multi-party system especially the Bloc Quebecois and the NDP for our inability to elect a majority now, or in the foreseeable future. All this of course is true, just as its true and ironic that many of the smaller special interest parties receive the bulk of their funding from the public purse. It just makes me shake my head, we are paying for the Bloc to block a possible majority and allowing them to disrupt the running of our parliament and split the country apart, only in Canada!
Anyway, the odds of this issue being addressed by the current government is nil. Their primary attempt at electoral reform is to create more ridings in areas where more Conservatives can be elected, that is, in rural areas and out west while improving representation by population (also a good idea). This may be our only hope, but its affects will not be felt for years.
In the meantime some groups are pushing for what is called proportional representation, an idea that was defeated in the last Ontario election in a referendum and would further fracture our already fractured parliament. If it weren't so serious, it would be funny.
