You're right, the schedule is tight, we've had students take CPSC 110 before. We've also had students who've received credits for those and are taking second year courses.

This is an interesting point. When we normalize for incoming grade, we sort of assume that this means that people who are getting similar grades in high school care equally about learning.

A funny thing happens though. It turns out the students who are offered a position in Science One, but who decline, actually have a higher incoming average than the group of students who end up taking Science One. However, this group that declines, ends up getting lower grades than those who take Science One in later years.

I certainly think there is an aspect of the program that has a selection effect for learning over grades, but that in university this mentality translates to better grades later on.

I'd also like to think that the program actually does provide some unique benefit for the students who take it. It's turns out that's a pretty hard thing to control for. We're trying.

I think it's worth it, but I'm biased: I'm one of the physics instructors for the program. We've recently added some computer science (mostly python) to the program. This was a first year doing it somewhat seriously and we're going to try and integrate it even more into all aspects of the program. There are also a couple final projects where you could choose to do something programming based.

The physics that you learn in Science One is at the same level as the first year honours physics courses taught at UBC, though we have a slightly different focus. We spend quite a bit of time trying to develop computation techniques for solving equations of motion.

The real strength of the program is that it's a very tight knit peer group. It's only 70 students with 9 instructors, and almost all your courses take place in the same classroom. We're all pretty close by the end of the year, which is an advantage, particularly if you're looking for reference letters.

The overall response from our Alumni is that it's worth it. Feel free to ask me more about the program.

edit: Please don't be dissuaded by our junky website. We're in the middle of getting it up graded. We have money, but ti turns out that it's harder to find the time.

[–]jimmycorpse 2ポイント3ポイント  (0子コメント)

It's my impression that most people in first year don't know what other kinds of jobs exist in sciences, so it's the default job.

If you're planning on that route, make sure to take physics 170 in addition to your regular physics courses. You'll also have to take some stuff in the Summer (APSCI 160 maybe?) to gain entry right into second year.

Physics 内の voynaimir によるリンク Are physical laws (e.g. F = dp/dt, curl E = -dB/dt) inherently linear or are they just a first-order approximation to the real phenomena?

[–]jimmycorpse 1ポイント2ポイント  (0子コメント)

It's the formula Newton originally wrote down. The worry is that is would change with relativity, much like Newtonian gravity gained corrections with the introduction of general relativity. We know understand that it's exact.

UBC 内の jwenna によるリンク how much math do you really need?

[–]jimmycorpse 6ポイント7ポイント  (0子コメント)

I'd take as much math and programming as you can, particularly if you're going into biology/microbiology. More and more biology is becoming a computational field. They're now able to model incredibly complex systems that no one ever dreamed before. Additionally, it's becoming a field more reliant on stochastic techniques and statistical analysis. I've been told by my colleges that the biggest issue with new biology graduate students is that they don't have a strong enough quantitative background to handle to work done in the lab.

Yeah, I use it in first year for two mainstream and two honours physics courses, though it's changing for one because someone form the department wrote a book.

[–]jimmycorpse 0ポイント1ポイント  (0子コメント)

It's a very thoughtful book. It's well written and does a good job at tackling difficult content head on. They put a lot of research into it. The instructor manual that comes with it has some very helpful hints about where student's blind spots are. The workbook contains some very conceptual problems in it (in the spirit of Lillian Mcdermott's Washington Tutorials) that I use as a basis of problems in class.

I use it to teach special relativity and quantum for a first year honours course (as well as the standard mechanics and e&m), and it's the foundation for our second year modern physics course.

AskScienceDiscussion 内の ShepardRTC によるリンク Could gravity be the result of interaction with the Higgs field?

[–]jimmycorpse 0ポイント1ポイント  (0子コメント)

Thanks.

Space-time curvature is what is described by string theory. There are limits of string theory in which the Einstein equations unexpectedly appear. The Einstein equations are what describe gravity in terms of curvature.

It was this discover that got people really excited about string theory. It actually started out, in the 70s, as a theory for the strong force, and when manipulating it, Einstein gravity popped out.

[–]jimmycorpse 5ポイント6ポイント  (0子コメント)

The Standard Model, which is the mathematical construct that the Higgs exists in, doesn't include gravity. Why something has mass and why things with mass feel gravitational force are two different questions.

The Standard Model tells us how the Higgs gives mass to fundamental particles and how the strong force gives additional mass to protons and neutrons and whatnot.

To find the gravitational force acting on these particles, we use these masses as inputs into our theories for gravity.

AskScienceDiscussion 内の maldoraf7 によるリンク Is it possible to have a visible clump of protons/electrons/neutrons? If so, what would properties would it have?

[–]jimmycorpse 2ポイント3ポイント  (0子コメント)

There's still plenty of protons and electrons and, depending on what equation of state you like, possibly other particles inside the neutron star. The most basic equation of state with the direct Urca has a proton fraction of 1/9, with an equal number of electrons to match. It's not like the protons and electrons disappear in the bulk of the object and only exist in the crust.

At this point however, I'm going to concede. If you think that the statement saying a white dwarf is a ball of electrons is dissimilar enough to saying a neutron star in like a ball of neutrons, I'm going to give it to you. I feel like this is one of those discussions which involve two people mostly talking past each other.

[–]jimmycorpse 0ポイント1ポイント  (0子コメント)

My sentence was meant to mirror your first sentence, where you talk about a neutron star as a lump of neutrons. If you're going to call a white dwarf a lump of the the three, then you might as well call a neutron star a lump of the three.

The interesting difference, which I'm sure you know, is that the white dwarf is supported by electron degeneracy, while the neutron star is supported by nuclear degeneracy, allowing us to cutely call it a lump of neutrons, or a lump of electrons.

I went to a chapman stick retreat once with a guy who knew Jaco later in his life. He said he was a wonderful human, but he could be really genuinely mean on cocaine. I think most of the bad stuff we hear about Jaco is from his self-destructive version, rather than the straight laced kid who made the music we love.

UBC 内の _oirectine によるリンク PHYS 101/102 vs PHYS 107/108/109

[–]jimmycorpse 0ポイント1ポイント  (0子コメント)

No problem. 107/108/109 are are all separate classes. 107/108 are the in-class physics courses. 109 is the lab course. The numbering is sort of strange.

Other than the difficulty, I don't think there's much to know other than the content of both the courses and labs in unlike 101/102. The labs in particular are fairly unique. If you want to to transfer to another university is can sometimes be difficult getting credit for the labs because they don't map to traditional labs.
