The (Multi) Universe(s)

Crossposted from Radiolab.org

Have you wondered if there is another you out there? Somewhere? Sitting in the same chair, reading the same blog post, wearing the same clothes and thinking the same thoughts? Well, Brian Greene says there must be one. Or two. Or lots and lots and lots and lots and… Why? You ask, well listen to Greene’s argument in this week’s podcast.

We are still furiously working on Season 5, so while you wait we bring you today’s podcast of a conversation between Robert Krulwich and Brian Greene, physics and mathematics professor and director of the Institute of Strings, Cosmology, and Astroparticle Physics at Columbia University. The interview is part of a series called “Giants of Science” hosted by venerable New York institution, the 92nd St Y.

Robert and Brian discuss what’s beyond the horizon of our universe, what you might wear in infinite universes with finite pairs of designer shoes, and why the Universe and swiss cheese have more in common than you think.

2008 CUPC at U of T

The following is a message from Sarah Kavassakis, the CUPC chair:

Dear Fellow Undergraduate Physics Students,

It is that time of year again, it is time for the Canadian Undergraduate Physics Conference! This year, the University of Toronto will be hosting the 44th CUPC, from October 16th – 20th, 2008. For those of you who aren't familar with the conference, it consists of four days of academic talks and lab tours relating to all areas of physics. Each student will be given a chance to present, with either a 15 minute talk or poster presentation, in either French or English, research that they themselves have conducted, as well as to listen to the work done by their peers. Typically, topics of undergraduate research are broadly grouped under astronomy and astrophysics, experimental physics, mathematical physics, computational physics, chemical physics and physical chemistry, planetary physics, biophysics, and engineering physics. Along with the opportunity to present their own work, attendees are also able to enjoy a series of key note lectures presented by well respected and established physicists who are at the top of their field. In the past, key note speakers at the CUPC have included John A. Wheeler, Richard P. Feynman, Freeman Dyson, and other incredible minds. 2008 will be no exception, our invited speakers for English talks so far include popular icons Lawrence Krauss and Lee Smolin and Nobel laureate John Polanyi. We are also currently preparing our list of French language speakers.

Keeping up with past years, and due to Toronto's ideal location for travel, the 44th CUPC is expecting 250-300 delegates from Canada and North America and a few dozen international students. The full registration fee is $300, which includes hotel accomodation for the four days of events and a ticket to the final Awards Banquet. For students not needing accomodation, the registration fee is $150. More information about fees and to register, go online to our website: http://cupc.ca . The conference hotel this year is the Courtyard, which is downtown Toronto, and minutes from the University of Toronto's St. George Campus, where our Department of Physics is located.

Our website also contains information about the various labs and external research groups that you will have an opportunity to visit as well as the "social events calender" for the conference. In the standard vein of the physics conference, the 2008 CUPC will feature a downtown Toronto pubcrawl (and alternatively, for those who aren't interested, a "dessert crawl"), opportunities for sightseeing, and a number of "meet and greets" to let you get to know your fellow students and fellow physicists. We will also be featuring an awards banquet on the final night where awards will be given out to the top three contributed student talks and the top three student poster presentations (as judged by a panel of grad students, pdfs, and faculty).

All students are welcome. Typically the conference is attended by 2nd, 3rd and 4th year undergraduates along with recent graduates (new grad students). Attendees can present any work that they conducted as an undergraduate (that is somehow connected to physics), from either a summer job, NSERC, a reading course, a lab or project course, undergraduate thesis, etc. Consult the website if you need more information about the types of presentations that are typically given, or feel free to email me (sarah.kavassalis@utoronto.ca), the 2008 host and organizing chair, with your questions.

Arrival of students happens all day on the Thursday (October 16th), with most students arriving in the late afternoon for the reception in the evening at the hotel. Friday (17th), Saturday (18th), and Sunday(19th) are full conference days, with the Awards Banquet taking place Sunday evening. Monday (October 20th) is a final breakfast at the hotel. Please make your travel arrangements with all of this in mind. Many students arrive late on Thursday and leave Sunday night (meaning only one missed day of class). Look at the "Coarse Schedule" (which is subject to minor changes) on our website for more information on timing.

I look forward to meeting you all in October.

Cheers,

Tell Me A Story

Radiolab's Robert Krulwich gave the commencement speech at California Institute of Technology. It's on the importance of scientific storytelling. More specifically, the importance of talking about and teaching science at a level all people can understand. I think it's a truly fantastic speech, have a listen.

Coffee Talk: Extra Dimensions!

Tonight's first ever Phys Soc Coffee Talk featuring Bruce Campbell went swimmingly and was received well by all! I think it's safe to say that this will become a regular occurrence. Keep posted for the next chance to meet a faculty member, other physics-enthusiasts, and learn about something you won't learn in lectures.

Here are some pictures from tonight (courtesy of Sam Dejong, applied phys).

This first one is of some of the students who attended the talk. From left to right there is Hass AbouZeid (applied phys), Alex Weekes (math), Mauricio Buschinelli (aerospace eng), and Renée Yoxon (that's me, experimental phys).

This is Dr. Bruce Campbell at the beginning of the talk giving the motivation for studying extra dimensions.


If you have any questions about the coffee talk or would like to e-mail us some feedback please contact us at the info on the right. Thanks to Dr. Bruce Campbell for taking the time to give us this great talk and thanks to everyone who came out to enjoy it.

See you all tomorrow at the CAP lecture and the squash tournament!

February/March Update

Hi everyone,

Now that reading week is over the physics society has many events underway. Here is an exhaustive list of planned events for the rest of February and into March.

Phys Soc Coffee Talk: On Thursday, February 28th, the physics society will be sitting down with Bruce Campbell, a member of the Carleton Theory team, to host a discussion entitled "Things That We Don't Know". The discussion will be held at Rooster's on the 4th floor Unicentre from 6 to 8pm.

Canadian Association of Physicists Lecture: On Friday, February 29th, Eldon Emberly from Simon Fraser University will be giving a talk entitled 'How cells measure space and time'. This will take place in Unicentre 180 at 10am. Don't miss it!

Abstract:

You don't have to look far to see the sophisticated technology that we have developed to measure space and time, whether it be the complex inner-workings of a watch or the GPS equipped compass that you might use on a backcountry expedition. But what about microorganisms? How is a microorganism, which calculates via biochemical reactions, able to make accurate measurements of time and space? In this talk I will highlight some of the amazing biological circuitry that cells use to keep time, showing how physical modeling can be used to gain insight into how these clocks function. But cells are also capable of measuring space - it's essential

that developing organisms put tissues where they are meant to be. I will discuss how cells measure their spatial location and how they overcome the complications of living in a noisy chemical environment.

Squash Tournament: The annual tournament will be held on February 29th and March 6th from 4 - 7pm . To sign up, talk to Steven Crane, visit HP 2221, or e-mail cuphyssoc@gmail.com. It's not too late to sign up! There is a 5$ registration fee.

Hockey Tournament: This will also be held in March. If interested in playing in this tournament talk to Mike Cunningham or Hass AbouZeid, visit HP 2221, or e-mail us. Dates also TBA.

Sudbury Neutrino Observatory: The plans for our annual trip to snow are underway. Please send us an e-mail early if you are interested. Priority will be given to upper year students who have not visited SNO yet. Plans will be finalized once we have an idea of how much interest there is.

Upcoming Phys Soc Executive Elections: It's that time of year to elect the exec members for the coming academic year. If interested in being nominated or nominating someone else drop by HP 2221 or send us an e-mail.

Hope to see you all on Thursday!

Renée
