6:18 PM | Leak Detector Down but Not Out, Code Crusher Code Objectified! Lab Book 2014_07_29
Alternate Title:  How Could Something So Pretty be So Broken?SummaryIt finally became too cumbersome to work with the can crusher simulation code in script form.  the bulk of this morning was spent in meetings and reworking the can crusher code to be object oriented.  The object oriented refactoring was completed and tested and works great!  It’s now very easy to run multiple simulations and compare their results.  The next step is to write code that runs the […]

5:51 PM | Quantum connection could revitalize superstrings
ContextHistory of Science,Quantum Physics by Tom Siegfried 4:30pm, July 30, 2014 Sometimes it’s nice to reflect nostalgically on the last couple of decades of the 20th century. You know, the era of Madonna and Duran Duran, Cheers and The X-Files, McGwire and Sosa, the Macarena, and superstring theory.Sadly, most of those are now just memories, although I guess Madonna is still around.

2:00 PM | San Diego Comic Con: Science and Cosplay
This last weekend, the Physics Central team traveled to San Diego to get people excited about physics. Of course, many Comic Con attendees need no convincing on that front (like Chewie! He loves our comic books!). Science and comics (not to mention science fiction) go hand in hand, mutually influencing and inspiring each other. We saw a bunch of science-themed costumes, and discovered that many of the cosplayers are actually scientists in disguise.Astronauts!Multiple incarnations of the 10th, […]

4:00 AM | L’importanza degli oceani per la vita aliena
Alcuni ricercatori della University of East Anglia (UEA) hanno condotto una serie di studi allo scopo di capire come si può sviluppare la vita sugli altri pianeti. I risultati suggeriscono che gli oceani rappresentano un fattore di vitale importanza per caratterizzare le condizioni climatiche sui pianeti simili alla Terra. Finora, la maggior parte delle simulazioni numeriche che […]

1:38 AM | Weather and statistics
I overheard the following conversation at the best coffee outlet on campus yesterday: "Well, winter's nearly over. We're past the shortest day so it's getting warmer. And we've had eleven frosts so far this year, and the record for Hamilton is twelve, so there can only be one more to come." - Anonymous Where do I begin? Well, first let's point out that the shortest day does not equal the coldest day. Not by a long shot. In fact, I believe that statistically speaking the coldest week […]

9:35 PM | SageMath, Where Objects Rock and Scripts Don't
I moved the Sage simulation of the can crusher to an object oriented implementation today.  A few days ago,I was worried this might have been a bit of overkill and just a subconcious desire on my part to place the project in a code format I'm used to seeing things in.  I hit an example yesterday that convinced me otherwiser, and only a few short, OK,  and somewhat grueling, hours later, I had a much easier to use OO simulator. Prior to yesterday, my usage mode of the can crusher […]

2:52 PM | Moving Crushed Can Walls! Lab Book 2014_07_28
Summary:I made the last few fixes on the can crusher code port from IDL to +Sage Mathematical Software System and the can wall is now moving in simulation.  For a refresher on what the can crusher does and why the wall moves in the first place, see the embedded can crusher video post below.  Graphs were created showing how the current through the driving coil varies with time when the can is allowed to move and when it is not.  The leak detector is still broken, work […]
