Subject Code/Name: [https://handbook.unimelb.edu.au/subjects/phyc10007/]PHYC10007 Physics for Biomedicine
Workload: Contact hours: 3x one lecture per week, 1x problem-solving class (tute) per week (starting from week 2) and 6x two and half hour laboratory sessions + 1 take-home experiment (up to 6 hours of work)
Total Time Commitment: Estimated total time commitment of 120 hours
Assessment: Ongoing assessment of practical work during the semester (25%); ten weekly assignments (10 x 1.5% = 15%); a 3-hour written examination in the examination period (60%).
Satisfactory completion of practical work is necessary to pass the subject (i.e. attendance and submission of work for at least 80% of workshop sessions together with a result for assessed work of at least 50%).
Lectopia Enabled: Yes, with screen capture. However, Professor Prawer often failed to use the recording system correctly, meaning the lecture wouldn’t always be recorded, would recommend attending his lectures at least
Past exams available: Yes, all the way back to 2008, however solutions were limited for more recent exams
Textbook Recommendation: Physics for the Life Sciences 3E, Martin Zinke-Allmag, Ken Sills, Rezza Nejat and Eduuardo Galiano-Riveros, Cengage Learning: ISBN 9780176558697
Very important as the lectures do not go into enough depth of what is examinable, and the suggested problems are often featured in the exam
Lecturer(s): Dr David Simpson: Weeks 1-6- Kinematics & Dynamics, Energy and Transport Phenomena, Vibrations & Waves
Prof Steven Prawer: Weeks 7-12- Electricity & Magnetism, Radiation & Imaging, Optics (but Steven fell very behind schedule so Optics was removed for 2019)
Year & Semester of completion: 2019 Semster 2
Rating: 1/5
Your Mark/Grade: TBD
Comments: All the reviews on here are quite outdated, Physics for Biomedince has changed quite a bit, so hopefully this is helpful for future students.
The first big change is Physics for Biomedicine only has 6 labs instead of 8 (woo yea!) instead we do a take-home experiment that is worth the equivalent of two labs. I think the coordination is much better compared to previous years, as rumours have suggested and our lectures although not amazing were sufficient.
Before I begin my review, its best I reveal that I hated physics before going into Biomedicine, I’ve always enjoyed sciences (bio & chem) but I could never understand physics and ended up not doing it in VCE and chose to do psych instead (best decision ever) even though my parents weren’t so happy I was doing a “fake science”. So as you can see I was not looking forward to this subject and after completing the horror of Chemistry for Biomedicine, Physics was not looking appealing.
Dr David Simpson takes you for the first six weeks and teaches you on Kinematics & Dynamics, Energy and Transport Phenomena, Vibrations & Waves. He is a great lecturer very clear and interesting, I personally never slept in his lectures and found is slides quite detailed and clear to read. The only problem was since he was a new lecturer he often uploaded his slides very late (like an hour before the lecture) which wasn’t ideal since I wanted to print the slides and write on them (which I would recommend for Physics for Biomedicine- handwrite your notes- so you are actively learning. David’s content looked scary at first but once you took some time to go over his slides and the textbook it wasn’t too bad. And many of us found his stuff easier compared to Steven’s (which I’ll go into later…). Make sure you try to over his lectures after each one and practise a question or two in the suggested problems to ensure you understand what is going on. It very easy to fall behind as the lectures build up for each other, so consistency is key, physics is hard but doable if you take the time to understand the content. In the lectures there always a demo- which is sometimes cool quite boring but they do illustrate the content being learnt so try to take notes of what is happening and why it occurs since the demonstrations are very much examinable in the final exam (popped up in the 2019 exam lol)
Steven then takes you for the final six weeks his content is Electricity & Magnetism, Radiation & Imaging, Optics. Steven was a boring lecturer his voice ended up getting annoying and was quite unengaging- however his long explanation is examinable and his questions focused more on the theory than the calculations. The great thing about Steven is he is very transparent he will tell you if something is important and will be on the exam (he told us that neurons would be 20 marks on the exam and this was indeed true) so there were no surprises there. However, his content was quite challenging and after doing the subject I still don’t know what was going on xD. For Steven’s content it is very important you attempt the suggested problems as he tends to just copy questions from there and put it on the exam, rewarding students who do the extra work.
The problem-solving classes were similar to math tutorials- answering question in a group on the whiteboard, my tutor was George and he was okay at explaining some of the stuff but often I would leave the class more confused going in, if you can try to have a look at the questions before going into tute and familiarise yourself with the formula and theory relevant to the tute, otherwise attendance is not compulsory, but recommended problem-solving questions have been on the exam before.
The seven practicals you complete are not all that fun, and can be draining- in your timetable it says the practical go for three hours- but it is only 2.5 hours. Before each practical, there is a pre-lab however they are not too challenging (except for the radiation one) and they contribute to your practical mark. Make sure you get the logbook and handbook as they are essential for the practicals.
Different demonstrators prefer different things in your report, all of which usually want you to follow the Predict-Observe-Explain model which is covered in your lab book and not hard to understand. My demonstrator, particularly wanted me to emphasise the conclusion (limitations and improvements for the experiment). When you pick your lab time you will also be randomly allocated in one of four groups; groups 1 & 2 do their labs in odd weeks, groups 3 & 4 do their labs in even weeks. I was in group 4 meaning I got to my lab after learning the content for the relevant practical, people in groups were 1 or 2 were unlucky because often we had not gone over the content for the lab. Now I will go over each practical. Being concise is key in your report, and often they marked quite nice for physics labs.
Experiment 1: Linear motion
As your first experiment, this is probably one of the toughest to finish on time (since none of us did) but the demonstrators are nice and they tell you this before the lab that they don’t expect you to finish so don’t stress. This experiment was probably the easiest theory wise you are simply moving the cart (similar to lectures) and recording position-time, velocity-time and acceleration-time graphs and understanding the relationship between all three. You will also explore Newton’s second law but this is not too bad you will find the force is proportional to the product of mass and acceleration.
Experiment 2: Energy conservation
Here, we investigate the difference between kinetic and potential energy and how energy is conserved- it is very easy to predict that you will be equating equations. Just keep in mind the formula for kinetic energy and you should be fine. I this experiment, you will be bouncing a ball and recording the curve and establishing the relationship between potential and kinetic energy and then you will compare this with an inclined plane.
Experiment 3: Gas laws
Probably one of the easiest experiments, as everything is centred to the ideal gas equation, here you will be blowing to a pipe and observing and how far deep will you no longer blow bubbles (be careful don’t blow too hard because water will flow out and you might get your lab partners wet). In the next part of this experiment, you will investigate the relationship between volume pressure which all relates to the ideal gas equation.
Experiment 4: Thermal effects
This experiment was pretty crap, least biomedical one there is. You will first explore heat transference which relates to colour spectrum and you will find which colours are absorbed more at different temperatures. Then you will look at energy absorption and cooling and simply comparing the absorptions of a black disc compared to a white disc.
Experiment 5: Ultrasound
One of the easiest experiments (and you’ll finish early) unfortunately you won’t be using medical ultrasound. Instead you will use some bootleg one, it is important for this lab you know before going in how to use each setting as this will save you plenty of time in the lab, this lab centres on the speed of sound which is great since you know you will be trying to achieve a value/ gradient of 343.
Experient 6: Radiation
I will not go into much detail in this lab since I wasn’t really sure what was going on but the physics demonstrators are nice and they marked quite nicely and I got full marks in it.
Experiment 7: Take home (group) experiment
You will either be given the muscles experiment or the worms experiment
In which for both you will be looking at some type of neural activity, once receiving your box you will decide on an experiment to do and perform ad submit a report of 500 words per person. Most of us did not know what was going and somehow managed to get good marks in it so do not stress about it. Our groups were not able to get any numerical data and we were still able to do well in just follow the lab manual and the BackyardBarns website and you will be fine. If you get a worm box you will need to use diluted vodka to anaesthetise them but be careful too much vodka and you will kill the worms. The group experiment is work\th two practicals (you will receive a group mark), the estimated time to complete the experiment is 3 hours but we were able to do it an hour, and the report won’t take you long.
The weekly assignments were an easy 15%, you three attempts to get it right which was nice, but some of them were quite hard and took over 30 minutes, they aren’t too bad just know that you should not just be doing the weekly assignments in order to do well in this subjects it is imperative you also do textbook questions.
The great thing about physics compared to Chem is that the exam is only 60% so it is not as stressful as compared to Chem.
The final exam is three hours in duration and worth 60% of your grade. It consists of short answer questions only, with a total of 120 marks. Each major topic is assigned a question on the exam, the exam is all short answer, with an even split of calculation and theory questions. Many of us were very stressed as the past exams were challenging and I went into to swot vac only able to answer 2-3 questions at most, but as previously mentioned the physics workshops during swot vac were great and the support the tutors provided was amazing they really did help to tackle each past exam question and get you into the mindset that you should approach each type of questions- with my favourite tip “If it is a theory question and you don’t know what’s going try to use common sense and bs an explanation and you might get a mark”. The exam was challenging, but I was able to have a go in every question which was nice I know I got some totally wrong but I was still able to attempt every question (except for the 2019 exam the radiation question was horrendous) but otherwise use swot vac wisely and you’ll be able to answer many questions in the exam. The exams follow a similar pattern and they tend to ask similar things every year, which is why it is important to do past exams as early as you can to familiarise yourself with the style of questions you will face on the exam. Three hours is not a lot of time I wasn’t able to finish the exam keep your eye on the clock and if you are stuck you are better off moving on to the next question.
Physics for Biomedicine is a pain, but if you were able to survive Chemistry you will be okay! Take some extra time to learn the content, apply it questions and you will do well. It is a challenging subject but very doable.
Good luck
