If by 14:00 I look pretty spacey coming out of my office now you know why #SOMA #NASA #MissionControl

I recently stumbled upon the perfect combination of ambient music and space-nerd geekdom. And it was right in iTunes (or equivalently on the web). SomaFM Mission Control is the bomb. Space-ambient music, but mixed in and out in the mix is the space to ground chatter between the astronauts and MC from Apollo and STS missions. Reminds me of as a young lad spending hours and hours in front of the TV during Mercury, Gemini and early Apollo missions. For a time most of my brain stored stats from hockey cards and NASA acyromns (anybody remember BECO, don’t know why just one of my faves).

“if I put this cable on from that side it will be twisted”

“roger, go 317 az”

“nope that will wrap”…….

And excuse me if I say niner instead of 9.

Should students @westernu pay for “the most expensive copyright insurance in CDN”?

In this columnist and University of Ottawa law professor Michael Geist questions the need for the recent agreement between the Association of Universities and Colleges Canada (which includes UWO) and its controversial new agreement with Access Copyright, which will cost students an extra $26 per full time student per year, in large part to get copyright access to materials that they can already access! Geist, who holds a Canada Research Chair in Internet and E-commerce Law, says

If that wasn’t enough, the model licence purports to grants rights for copying that does not require permission. For example, it defines copying as including “posting a link or hyperlink to a digital copy”, yet linking to content can hardly be described as copying materials.

If would even prevent storing articles in cloud services such as Dropbox! I’m not going to get too excited since the company is covering my costs on this one so what the heck.

But maybe you should!

April 2012: a big month for birds and physics!

Birds and physics, physics and birds, like peanut butter and jelly or rum and coke, right? Sure. So who was surprised this month when reading this story about how some migratory birds sense optimum pressure gradient situations to ride the pressure ridges on fronts to save time and energy, such as the godwit (shown below).

 

Keeping up with the godwits is hard work. Not to be outdone, new evidence has come to light concerning the magnetic sensing abilities of pigeons. Scientists at Baylor University have found that cells in the bird’s inner ears that sense the magnetic field vector. Furthermore, it appears the hippocampus region of the brain in these birds allows them to store maps to navigate. The same brain activity occurs in people. Bird-brained indeed!

Harper Government to Close Only High Arctic Ozone Monitoring Site @saveEC #AprilFool ?

The Harper Government is proceeding with its plan to close Canada’s only high Arctic research station for atmospheric measurements including ozone. In last week’s budget they (re) announced that one of these days they would be building a new facility. Unfortunately they have insisted on building it so far south it would have likely be unable to monitor events like last winter’s Arctic Ozone Hole. No plans for filling in the data record for the years until the new facility is available were given, nor what expertise would remain of the current generation of young Canadian atmospheric scientists to operate it.

OK, I’ve been April Fooling you all morning. But it’s afternoon now and THIS IS REAL! For further information or to help out please go to the CANDAC website or Save Environment Canada websites.

2012 Budget Requires Canadian Scientists to Use Government Approved List of Physical Constants. #NRC #cdnpoli

There were almost no big surprises in the new federal budget. For science, (as discussed on this blog by Prof. Chronik) most of the changes were given earlier in the Jenkins report and concerned changes in research/industrial partnerships between NRC and the private sector. But no one reading the tea leaves was prepared for what was apparently a last minute addition by scientific policy advisors to Chapter 3, Supporting Jobs and Growth.

The Government requires all scientists, engineers and astrologers receiving federal funding to immediately use the following constants.

  • the value of pi shall now be 22/7
  • the following constants shall be increased by a surtax of 5%: the speed of light, the universal gas constant, Avogadro’s Number and the Love Number
  • conversions from the metric to English system will now be tied to the Canadian dollar
  • the Froude number may not be publicly displayed in any Federal building
  • the value of the Hubble constant shall be revised to reflect the correct age of the Universe, 6000 years.
  • the federal government is responsible for funding research which uses constants for the determination of irradiance, the provinces are responsible for funding research which includes determination of radiance.
  • the provinces are responsible for funding any research involving the following constants: Loschmidt Number, Stefan-Boltzmann radiation constant, Rydberg constant and acceleration due to gravity.
  • introduction of Stockwell’s number (number of unreported crimes occurring per minute in Canada).

@cern to relocate #LHC to atrium of Physics & Astronomy Bldg @westernu

It started with some ideas for a few hands-on exhibits, grew to a small Foucault pendulum and then the Chair of the Department of Physics, Astronomy and Enology at Occidental Université (formally the Easterly University of Northerly Ontario), Prof. S. Basu said enough is enough. “If we keep thinking small we will stay small” he told a group of reporters anxious for the 411 on this latest coup for Occidental.

Prof. Basu called CERN director general Rolf-Dieter Heuer and laid it on the line: give us the Large Hadron Collider. “I told him we have a world-class building with the latest renovations and due to the topology of the landscape we are built on neutrinos should be moving at least at 2c as they whiz through our building. He said deal and we’re in the process of making a few tweaks in the atrium design to accommodate the main storage ring.”

The Large Hadron Collider (LHC) currently sits in a circular tunnel 27 km in circumference. The tunnel is buried around 50 to 175 m underground and straddles the border between Switzerland and France. How will the atrium accommodate it, Basu was asked. “The Euros goofed when they designed LHC and they knew it. Special relativity tells that though we see the ring having a circumference of 27 km the particles in the ring, moving near the speed of light, see the tunnel as having a circumference about the diameter of our atrium. So there is no need for such a huge tunnel, it was a political move so the French would pony up big bucks.”

Basu went on to discuss how the Department would produce twin particles, of which one particle would stay in the centre of the ring and the other could be accelerated by a student around the ring a few times and come back 100 years older than its twin and with a long grey beard. The installation is expected to come online when the building renovations are finished in 2525 (“if Man is still alive”).

UWO Prof Uses His Meteorology Skills to Solve Campus Fainting Mystery #westernu

Easterly University of Northerly Ontario (formally Westward University of Southward Ontario) Professor of Lidarology R. J. Sica was called in by the Provost who had a most unusual problem. “We don’t understand it, but this winter students have been dropping like flies on campus during the day, particularly during the 10 min periods between class changes. Since your Department has all the brains in this place we thought you could solve the mystery.”

Prof. Sica replied he would get to the bottom of it, because frankly he really had nothing else to do in his cushy position except for occasionally diving out of the wall of falling valances. Here is part of the Executive Summary of his final report, which you can view in its entirety here.

Students were observed moving between classes. I notice a large fraction of one of the genders had Canada Goose South Pole Expedition parkas on. Having lived in interior Alaska for several long, cold, dark winters, I knew that these coats were typically uncomfortably warm in Fairbanks during January, when the average temperature was –25C. This winter the temperature seldom got down to +5C. However, as I watched the weak collapse in the herd of students leaving Nat Sci 145 I observed that not all the students in the parkas dropped. I had to be missing something. Then it came to me. The parkas were generating an additional 1000 W of body heat, but when worn with heels the excess heat could dump to the ground through the feet. The students who dropped were all wearing Uggs with the coats. The combination of the Canada Goose Expedition Parkas, Uggs and balmy temperatures were the perfect negative storm, producing temperatures equivalent to solar chromosphere near the body of the wearer.

These results were verified by Crow Emily, shown here standing barefoot in the Eureka, NWT as part of a 30 min experiment to determine if she would get cold or not. Funny, I haven’t heard anything back from her yet?
