About SI for this Course

Supplemental Instruction is provided online via WebEx during the period of online classes. Join my SI sessions by using this link:

Due to potential unforeseen obstacles SI Leaders may encounter as they move to online delivery, some sessions may be modified, cancelled, or suspended until in-person sessions can resume on campus.

I'm Ben B, a Sophomore physics major here with you guys at ISU. Some of my favorite (non-physics) things include hot sauce, the video game Tetris, and ultimate frisbee. If you have any questions about physics, this course, or anything else, you can message me through the contact your SI leader link on the side of this page.

I know how hard physics can be. Physics 222 is a challenging course, I know, but it's also got some of the coolest ideas in science involved in it. If you stick with it, you will really have your mind blown, I promise.

My sessions are typically focused on solving problems, since that is by and far the best way to learn physics. If you have any suggestions, comments, or complaints about how I run sessions, I am all ears. Just message me through the contact your SI leader link on the side.

My favorite physics joke:
Heisenberg, Einstein, and Schrodinger were driving down the highway one day, until a police officer pulls them over. The officer walks up to the car and asks, "Do you have any idea how fast you were going?" Heisenberg replies with "No, but I know exactly where I am." Einstein quickly chimes in, and says "You know, it looked to me like you were the one who was speeding." The officer suspects the scientists are under the influence, and goes to check the trunk of the vehicle. When he opens it, he finds a dead cat, and asks "Did you know there's a dead cat in here?" and Schrodinger replies "Well I do now."


Online Resources for Physics 222 (3 of 3)

2) Hyperphysics: I mentioned this in the beginning of the course, but Hyperphysics is a great tool for really getting used to the equations we're using in this class. The website is a bit hard to use, but clicking around will usually bring you to exactly what you need, at least eventually.
3) Desmos: I've talked about desmos before in my sessions, but now that everything is online, I think Desmos is going to be even more useful. It's a calculator that handles scientific notation really well, you can assign variables dynamic values in it, and it's got great decimal precision. I highly recommend you do your homework using this calculator, rather than your TI-84.

Now some links that I think are really helpful for content:
1) Youtube videos: I'm not the only person who really loves talking about physics. If you look this stuff up on youtube, you'll find that there are a ton of videos about electricity and magnetism that explain things really well. One channel I really like is Science Asylum, who has a whole playlist on electrodynamics, with really great visuals. There's also 3blue1brown's video on Maxwell's Equations that gives a good visual intuition about how the magnetic and electric fields behave. There are plenty of other videos that are great at explaining these things, so just try looking them up if you're confused on a topic.

Now that we're online for the rest of the semester, I thought it would be a good time to post some resources for learning physics.
First, I want to make sure everyone is aware that I have a website, which is how I post these announcements. To find it, google Iowa State SI, then scroll down to physics 222, and click on the course. You'll be taken to my page, where all of the worksheets and announcements are posted. You can also message me through the website. On the sidebar, just click the Message My SI Leader option. I'll get back to you as soon as I can.
I'm a resource for you guys, and I really enjoy helping out. I will do my best to help you with any problems you are struggling with, and explain something that you find confusing.

Online SI and Some Updates

Hey everyone,
So I know this is a hectic time with a lot of uncertainty about what is going to happen with online classes, grades, and everything else. Thankfully, one thing you can be certain of are the laws of physics. Those don't care about this whole Coronavirus thing.
As a reminder, I will be hosting my sessions on WebEX as instructed by the SI department. The sessions will be held at the same time as usual, and probably will be done in approximately the same format. I'm going to do my best to keep them interesting, but I am honestly unsure of how I will do that at the moment. (I may try to stream something physics related on twitch, where it might be easier/less intimidating to ask questions. That's not guaranteed however.)
Check your emails. There are instructions on how to access WebEX there, and message me with questions.

Solitary Instruction (aka Online SI)

Online classes! Coronavirus! Physics! What will happen to SI?
These are all important questions that I'm sure we're all very worried about in the days before spring break. Here's the news: SI is still happening during the online classes.
It seems likely that the sessions will be held via WebEX. They will be at the same time as usual. This is about all I know. I'll keep you guys posted with info on how SI is happening, but know that I'm still going to be doing my job while we are online. Please keep an eye on this website and your emails while during this transition.
As usual, message me with any questions you have. I hope everyone has a good spring break, stay healthy, and keep doing physics.
