Have you Thought About Taking Online Classes During the Summer?

Have you ever thought of taking online classes during the summer to increase your chances of graduating early? It is not too late to register for this summer! That’s the path I took for the past two summers while also doing an internship. I have talked about Online vs. Regular Classes previously, but now I have gathered two stories of students who took online classes while also doing an internship or working a full-time position. Overall, they were great and recommended experiences:

“I took International Business during Summer 2016 while on internship with Alaska Airlines. My professor was great, and he posted video lectures online each week, so I would watch his chapter lecture, read the chapter, and do discussion posts. We could do the posts on our own time, as long as they were done by the end of the week. Additionally, we had a group project to do, which was challenging because one of my group members went on vacation and didn’t do her part. I believe we had also two exams, which were obviously open book. Lastly, we had a final paper, in which we had to write a business plan for how we would expand our American company into international markets.

I probably spent 30 min to 1 hour each night doing homework or reading the textbook (3 to 4 hours per week). Towards the end of the class I spent more time on the class, since I had a final paper to write. It was pretty easy to take a class during my internship. I started the online class a week before my internship, so I had a feel for it before I jumped into working full time. I worked 40 hours per week (typically 8am to 5pm) with an additional hour of commute each way. Once I got home I would do some homework for my online class. I spaced out my homework throughout the week so that I wouldn’t have to spend my weekends doing homework (since I had flight benefits and wanted to travel!).

I really liked combining an online class with my internship. I felt like I was being very productive over the summer. My manager at my internship was very impressed that I was able to take classes along with working full time.” Lindsey Hanbidge, ERAU Daytona 2017 Graduating Senior

“During the summer of 2016, I took a Leadership online class as an elective while working full-time at an airport for a ground handling company. The class was straightforward and included weekly discussions and assignments. We also had a term paper and a final exam. I would say that I spent on average 3-4 hours per week on that class. It was crucial to set a side a time during the week to sit down with no distractions and knock out my class work. If you put it off until Sunday night each week, you will definitely regret it. With all that said, working full-time and taking an online class at the same time is totally feasible and totally recommended!” – Jake Neville, ERAU Daytona Class of 2016

Editor’s note: Current residential campus students must submit appropriate paperwork before enrolling in online courses through the Worldwide Campus. Consult with the Record’s Office, your advisor or program coordinator before deciding whether online courses are right for you. 

Simulating Giant Sound Waves on Mars

Hello, again!

It’s time for another installment of “a day in the life of an awesome physics student at Embry-Riddle.”

Well the summer is in full swing; I had my first exam on Thursday, which was also my first exam of grad school, as the class I’m taking is my first master’s class for the accelerated degree. I was really confident, which means I either aced the exam or bombed it – you never really know until you get your results back. I’ve never taken summer classes before, but so far I think it’s pretty awesome. The material moves at a quick yet manageable pace, and it’s nice to only have one class to worry about after the last four semesters of 16-17 credits. My only complaint about summer classes is the “summer” part – why is it so hot outside? It’s unnatural. I really wasn’t born to live in the south; I can handle a -20º wind-chill, but as soon as the thermometer climbs above 90º that’s when I give up and hide inside. Not to mention it rains so much! (I promise I won’t complain about the weather in every entry.)

I’ve had a lot of free time, which is unusual for me, so it’s been nice. Lately I’ve been learning some new acoustic guitar songs, watching old seasons of Buffy the Vampire Slayer, and leveling a blood elf warlock. And let me just take a moment to talk about how much I love living in my own apartment off campus. Everything is finally clean, unpacked, and decorated to my liking, and I can listen to loud music in any room at any time and nobody complains about my volume, musical tastes, or singing. It’s great. I live only two minutes from campus, so it’s a nice, short commute every day. Once I figure out how to reduce my electric bill everything will be perfect!

My days are spent sitting up in the Lehman Building’s Space Physics Research Lab (which will henceforth be referred to as “SPRL”) working on my project for the CEDAR conference in late-June. I mentioned it briefly in the last entry, but I think I should elaborate, since that’s what got me this gig as a blogger. CEDAR (which stands for “Coupling, Energetics, and Dynamics of Atmospheric regions”) is an NSF-sponsered yearly atmospheric sciences meeting that focuses on instrumentation and modeling of the middle and upper atmosphere. I am working with Dr. Snively in the Department of Physical Sciences to adapt his atmospheric wave model to Martian conditions so that we can see how atmospheric acoustic and gravity waves, which are a bit like ocean waves, but in the atmosphere, propagate on Mars in comparison to Earth (if you’re interested, my project abstract is here).

Some plots of relevant atmospheric data on Mars generated by the profile used in our simulations.

We are using MarsGRAM (Mars Global Reference Atomic Model) data provided by NASA’s Marshall Space Flight Center to specify many different properties of the atmosphere, which has proven very interesting! This data is then used to generate a profile, which essentially shows the temperature, density, pressure, etc. as you travel up through the atmosphere (it’s really just a big table of numbers), and then the profile is loaded into the wave dynamics model. The model produces a simulation based on some inputs, such as frequency, amplitude, etc., and we watch how the wave behaves as it moves upward.

Animation of a nonlinear acoustic wave traveling up through the Martian atmosphere. The one-dimensional simulation is laid over the two-dimensional simulation in order to determine that the results of each are valid. This wave has a frequency of 0.032 Hz, which corresponds to a wavelength of about 31 km. (Click on thumbnail to watch animation.) Note that the axes correspond to the 2-D results (and are in meters – please disregard the error in the labeling.)

This past week we successfully simulated an acoustic wave in both a one-dimensional and two-dimensional model and confirmed that the results agreed. Acoustic waves are really cool – they are essentially giant sound waves that move up through the atmosphere until the air becomes too sparse and viscous, causing them to dissipate. We’ve found that this happens really quickly on Mars compared to Earth, due to the increasing viscosity at higher altitudes. The waves we have been simulating have frequencies of about 0.03 Hz. For perspective, note that the average human can hear frequencies ranging from 20-20,000 Hz, so these waves are much larger and lower-frequency than ordinary sound waves.

The next phase of the project is to simulate two-dimensional gravity waves, which I will talk about in my next entry!

Before I close out this entry, I wanted to touch back on what I said last time about going where life takes you. I came into Riddle as an Aerospace Engineering student, but was converted to Engineering Physics after my first semester due to the fact that I love physics and space and don’t really care about designing airplanes (blasphemy, I know.) Deep down I definitely feel like an EP student, and never once regret my change. In fact, the more I go through my coursework, the more I find myself leaning towards physics and research and away from actual engineering – I took the “gauntlet” (solids, dynamics, and fluids, which are engineering sciences classes you take your sophomore year), and pretty much hated them (though I did like fluids, but that was because professor Davids is awesome!) Plus I am loving what I am doing here in SPRL. I’ve been thinking a lot about what I’m going to do after Riddle, and, while my plan had always been BS then MS then Work in engineering then PhD maybe later, I am thinking more about going straight onto my PhD and getting involved in space and astrophysics research.

Tune in next week, I’ll have some really cool Mars stuff to share with y’all! (Yeah, I’m becoming a southerner. I say that now.) Be sure to email me if there’s anything you’d like me to write about Riddle, otherwise I’ll just keep rambling on about my life in every entry.

Hey guys. The spring semester has officially ended and I can’t wait for Summer A to start! Check-in for dorms started yesterday and continues thru today and classes begin tomorrow. I can’t wait for this summer. I already started having fun. The past two days I flew with friends to Tampa and visited Busch Gardens, walked around St. Petersburg and went to the mall in Brandon. It was a fun 2 days away from campus.

Classes last semester were awesome, especially grades. Finals went really well and were as smooth as possible. I will enjoy my all-female professor schedule for the summer and fall, haha. I am excited to take AT 200 (Air Traffic Management I) and BA 314 (Human Resource Management) for the first summer session. For BA 314, my professor already assigned us homework on Monday!

So far everything is going great. I move out of my room in McKay to my summer room in Adams. I am not looking forward to moving because I have so much stuff! It’s going to be a challenge and it has to get done. I will be a busy traveler this summer and also a studious student. I am going to enjoy the next few months as much as possible.

If you guys have any questions at all about anything at all, please feel free to email me. I appreciate the guys that have emailed me and I am glad to answer your questions. I am here to be a good resource for you guys so if can assist in any way please let me know. Tuition deposit was due May 1st, you can still make the deposit ASAP, and the housing deposit is due June 1st. Remember to file your FAFSA and contact admissions if you have any questions about the application or financial aid in general. I wish you guys luck in your admission process and hope to see you on campus in the fall.

Best wishes and safe skies,

Hey guys. There are only two more weeks until finals week… wooo hoooo! I am so excited for the end of this semester and school year. So much has happened and I had a lot of experiences. I wish my freshmen year would never end, it seems like only yesterday I was just the new kid on campus. But we gotta grow up some day! It’s been really hectic the past few weeks, getting final projects and assignments done and ready to hand in and also trying not to slack off at the last minute. With all that said, I only have two finals, BA 201 [Principles of Management] and PSY 101 [Introduction to Psychology]. I am working really hard to make sure I do exceptionally well this semester.

I will be doing summer classes this year in an effort to get certain classes out the way that are required for my new major. Seeing that I switched this semester, I think it will put in the place I need to be academically for the fall. I will be going home at the end of this semester for 4 days before I return back to Daytona to start summer classes. I am looking forward to taking these classes and spending time with a few friends that will be here for summer.

So far, ERRSA has been great. We are still working on the bid process to have the SACURH conference on our campus for 2011 [changed from 2010]. This week we selected our committee chairs and assigned people certain assignments to have done by the next meeting. First Generation is also great. At Relay for Life, we placed second overall for the team with most spirit award! It was 6 of us that stayed from 6 p.m. Friday night until 6 a.m. Saturday morning. We ran and walked a lot of laps. All together we did about 96 miles for the entire night. We have a lot of activities planned for the next 2 weeks to wrap up a fun filled semester.

Many of you know that Sneak Preview will be held on April 18th. I will be giving tours as an ERRSA member. I suggest those of you that haven’t registered to attend to do so ASAP if you are able to make it to the area.

I can’t wait to go back home to see family for a few days before summer classes. I miss them so much.

Again guys, if there are any questions that you have about anything at all, please feel free to email me. I am here to answer to the best of my ability, any questions that you may have. For those of you that accepted your admission to Embry-Riddle, congratulations, I hope to see you in the fall. Remember to get your FAFSA applications in and also to send in your housing contracts and all fees and documents needed to finalize your admission. Thanks to all of you guys that emailed me, I appreciate the comments. Keep on reading and always strive for the best in whatever you do.

Best wishes,
