Editor’s note: This is a reprint of a (slightly edited) paper of the same title that appeared in the book Physics and Our World: A Symposium in Honor of Victor F. Weiskopf, published by the American Journal of Physics (1976). The personal tone of the original talk has been preserved in the paper, which was itself a slightly edited transcript of a tape. The figures reproduce transparencies used in the talk. The demonstration involved a tall rectangular transparent vessel of corn syrup, projected by an overhead projector turned on its side. Some essential hand waving could not be reproduced.

In Maritime Technology Programme at the School of Ocean Engineering, Universiti Malaysia Terengganu, the final year project typically start at the third year second semester. At the start of the semester, the student roams around to find supervisors, eventually getting the final year project title assigned to them.
Normally in a semester, there would be at least 10 active lecturers are able to serve the 60 students per semester. Therefore ideally a lecturer shall be assigned 10 students by the Final Year Project Coordinator. However, as some of the lecturer hold some university administrative duty (e.g. Dean/Deputy Dean of School, Director/Deputy Director) they might be assigned two or three students.
In discussing about surviving Final Year Project, such topic can be divided into two facets; supervisor’s responsibilities and student’s responsibilities. A Final Year Project is a mutual cooperation between the student and the supervisor, where both shall diligently spend time together in solving the assigned problem. With that said, the content discussed below can also be applied to the Post-Graduate Research as well.
A supervisor’s responsibility is to make sure that the student is mentored to solve the assigned student’s project. In Final Year Project, a student is expected to conduct an individual independent project that combines various subjects to solve a problem that span across 2/3 research objectives. In this phase, the term independent doesn’t mean that the student are being left to solve the assigned title. The supervisor must make sure that the student are given enough resources (notes, discussions, hardware, consumables) to assist the student to finish the project.
A student’s responsibility is to finish the Final Year Project properly using the tools, knowledge obtained spanning across the earlier academic years and discussion with the supervisors. The student must catch the supervisor through appointments and ready to present progresses from time to time. Typically students who registered in the Final Year Project have small number of credit hours. Therefore the most of the time, the student shall spend their time in the lab/workshop to finish his/her projects.
Student’s readiness: I believe in maturity. That said, it should be made clear that maturity doesn’t really tied with age, but through experiences. Historically, for a 4-year programme, the university send their student to internship in the second semester of the 3rd year and come back to finish another year in the university which the student finally took the Final Year Project in the last two semesters. These students are hardened, matured due to the internship in the third year, which results for high quality work and overall great attitude in finishing their project.
Nowadays, the system was changed. The students are required to take the Final Year Project in the second semester of the 3rd year and the first semester of the 4th year, then on the last semester the student shall leave the university for internship. During this time, it is up to the lecturers to harden up the student to get the student ready with suitable work attitude before leaving the university. This, of course a tough job, which calls for blood, sweat and tears for both the supervisors and the students, to equip the student with maturity while finishing the project.
Setting Expectations: A Final Year Project is normally assessed based on the objectives defined in the earlier stage. Therefore having a proper plan of execution is very important. As one wise guy said, ‘execution is king’, which means that a great idea is not really worth that much compared with the set of good execution. Frequent progress meeting calls for good progress, based from the expectations being set earlier. With that, I honestly think a weekly meeting on start of the week or the end of the week is important to make sure the student can progress with sensible directions and guidance from the supervisors.
To end this essay, I list here some tips for a smooth journey in completing Final Year Project/Post-Graduate Research:
- Make a point to see supervisor at least once a week. This is to make sure that the supervisor know that you are alive and progressing in your work.
- Utilize your log book. A log book is not for collecting your supervisor’s signature. A log book should be used to plan your experiments, record the relevant literature, record your findings and your ideas.
- Use time wisely. When I was in Japan, I notice the student do sleep in their lab. It was an engineering lab, so imagine how serious they take pride of their work.
- Be honest. Telling your supervisor that you work so hard without showing your results is only revealing that you are dishonest. Show the supervisor what worked and what doesn’t. Normally a project given are impossible to fail, anyway it’s a Final Year Project, not really to uncover the frontier of unknown. Never cheat your result. It will bite you later.
- Say no to plagiarism. Now, say it and repeat it 100 times, and put it deep in your heart. I’ve seen people lost their degree, and their jobs due to plagiarism. You don’t want people to lost their trust to you, right?
- Work faster. Yep. Never spend a year to finish your first objective. Move fast, break stuff, learn something.
- Write. At least one paragraph per day. It’s not that hard doesn’t it?
- Speak. Learn how to deliver great presentations. Don’t be a wood on the stage. In the age of internet, there are various of sources in the internet to conduct presentations properly.
- Focus. In the age of internet, I’ve noticed that our young minds of today are only interested in four things; Useless articles in Facebook, Twitter, Instagram, and Youtube. Don’t waste your time to be entertained, start working, earn billions, or millions or thousands.
- Attitude is everything. Great attitude bring you to places, bad attitude (coming late to the lab, absent from the lab without telling your supervisor in advance, run away from project, unnecessary defensiveness) will earn you bad rep and bad future. I have tonnes of stories, but let’s just leave it there.
The 8th National Technical Seminar on Underwater System Technology 2015 (NUSYS’15) was organized on the 21th September 2015 at the Institut Oseanografi & Sekitaran (INOS), Universiti Malaysia Terengganu (UMT), Malaysia. The national seminar was jointly organized by Universiti Malaysia Terengganu (UMT), Universiti Sains Malaysia (USM), Universiti Teknologi Petronas (UTP), Universiti Teknologi Malaysia (UTM), IEEE-OES and Subsea Explore services Sdn. Bhd. About 180 delegates among university and industrial researchers attended the seminar.
The objectives of the seminar are threefold;
- To accommodate a medium to discuss wide range of underwater system technology between universities and industries.
- To disseminate the latest technology in the field of underwater engineering
- To provide an opportunity for researchers and industries to explore the current practices in underwater system technology.
The seminar was officiated by the Political Secretary of the Ministry of Higher Education, Datuk Hj. Abd Halim Bin Jusoh, followed by a keynote address by Prof. Dato’ Dr. Nor Aieni Binti Haji Mokhtar, entitled “Diving to the Future of Underwater Technology”. The themes set by the keynote address were followed by five technical speakers delivered by representatives from universities and industries, which are;
- Decommissioning of Offshore Platform, Assoc. Prof. Ir. Dr. Mohd Shahir Liew, Universiti Teknologi PETRONAS.
- Latest Technology in Subsea Engineering Practices, Mr. Syamsul Nizam, Subsea Explore Services Sdn. Bhd.
- Subsea Riser and Pipelines, Assoc. Prof. Dr. Norhazilan Md. Noor, Universiti Teknologi Malaysia.
- Subsea Pro Simulation, Dr. Jaswar Koto, Universiti Teknologi Malaysia.
- Innovations in Underwater Engineering and Technologies, Dr. Ahmad Faisal Mohamad Ayob, Universiti Malaysia Terengganu.
A round table forum and discussions were conducted in the afternoon sessions under the theme of “The Frontier of Underwater Engineering and Technologies”. The discussions were moderated by Assoc. Prof. Dr. Khalid Samo with four panels; Prof. Dr. Rizal Arshad, Assoc. Prof. Dr. Norhazilan Md. Noor, Dr. Jaswar Koto and Mr. Syamsul Nizam. The forum aimed to raise the awareness regarding the issues governing the underwater engineering and the methods to counter and improve upon the issues.
The industrial counterpart represented by Mr. Syamsul Nizam encouraged the participants to contribute in a small and incremental way i.e. in a form of building blocks that can be shared and used by other teams. Such methods shall ease the design burden and focused on smaller dimension of issues such as thrusters, visualization, communication and workflow.
Assoc. Prof. Dr. Norhazilan highlighted that the current subsea piping system technologies has reached its maturity. Therefore he encouraged that a more intelligent system should be proposed to conduct preventive maintenance and reduce the risk of loss due to unexpected downtime.
Dr. Jaswar Koto encouraged the participants among students to utilize free software that was developed by Joint International Research Center of Subsea Technology. The Subsea Pro Software can be accessed via http://isomase.org/SRC_Software.php.
The forum also received a support from IEEE Ocean Engineering Society (IEEE-OES) Malaysia represented by Prof. Dr. Rizal Arshad. He envisaged that the participants should be backed by a society to further promote the progression of ocean engineering discipline through established networks of researchers offered by IEEE-OES Malaysia.
NUSYS 2015 received massive coverage from printed media due to the promotion of radical ideas such as offshore platform as undergraduate and research lab, and due to the seminar as the most proper media to disseminate the state of the art knowledge in ocean engineering, specifically in underwater technology.

My first keynote address!! I was very excited to share the experience gathered from the my reseach that has been mentored by Assoc. Prof. Dr. Rizal Arshad from URCG, USM. There were lots of issues that I’ve brought to the table to be think about, and some future hopes on the status of reseach in the area of sea-to-space. Particularly on widening the aspect of research, opening for new research collaborations and many more. I’ll be looking forward to come back to the seminar next year to share new findings and experience to the members.
