Learning contract (1)

•  We will start the course on 07:30 a.m. If Pak Sunu doesn’t come without any no7fica7on to class coordinator un7l 08:00 a.m., you can leave the class room. If you come late ader 08:00 a.m. and class has started, you can close the door from the outside.

•  No TA (!!p absen) is permieed. If you do it, and Pak Sunu gets all evidences, you and your friend will be eliminated from the class. If you want to help your country, let’s do “no corrup7on” on ourselves.

•  If you need to make permission for family maeer, or you are ill, please send an emergency SMS to Pak Sunu (0811-‐283-‐446), write your name. Common communica7on will be done by Whats App (+81-‐80-‐4616-‐2606). Don’t forget to send permission leeer to Kantor Administrasi Akademik S2 later on (Mas Dedy).

Learning contract (2)

•  You can discuss your assignment with your friend, but don’t give your exact answer and source code to your friends. No chea7ng on assignment. Plagiarism will be followed by giving 0 (zero) mark on assignment.

•  Assignment should be submieed on A4 paper. Do not use smaller size paper (B5 / binder paper).

•  Midterm and final exam should be done with honesty. Chea7ng is not permieed. On-‐site evidence (such as: wrieen report from officer and photograph) will be processed directly and you will get “E” on your mark. Zero tolerance for dishonesty.

•  Please change your smartphone mode to “silent mode”. Personal computer should be shut down or “sleep”, except Pak Sunu asks you to use your MATLAB during the class.

Class coordinator (CC)? •  CC has right to ask one of his/her friends to maintain Facebook Page for communica7on.

•  CC is responsible to manage communica7on between class member and Pak Sunu, and vice versa.

•  Pak Sunu will send SMS to CC in emergency case (trapped in severe traffic jam or accident, and family maeer). Class will be cancelled and changed to other day if Pak Sunu cannot come (only by reason). CC will broadcast the SMS to student’s WA group and FB page.

•  In future, I will priori7ze all CCs when they are applying for thesis supervision ☺

•  Mas Yas Ahmad (0855-‐9918-‐983)

Marking procedure

•  Mark from Pak Sunu includes: •  Final examina7on : 60%

•  Midterm examina7on : 25% •  Group presenta7on / Assign. : 15%

NB: You should aeend least 80% of lectures (12 of 14 lectures) to join final exam (UAS).

QUESTION ?

Outlines






What is Science ? •  Oxford Dic7onaries: “The intellectual and prac7cal ac7vity encompassing the systema7c study of the structure and behavior of the physical and natural world through observa7on and experiment”

•  Frederick Grinnell in “The Scien7fic Aotude: “….it is useful to think of science as a serious game played according to rules that are agreed to by scien7sts”

•  Rule: what counts as evidence in observa7on and permissible ways in which the evidence can be presented.

What is the ScientiOic Method?

•  What are the steps in the scientific method? Take two minutes to write down the steps we use in science, and I will try to dig your opinion ☺

Steps in ScientiOic Method

• Characteriza7on of problem from exis7ng data •  Formula7on of a hypothesis

•  Experimental tes7ng • Analysis of experiment results • Validate or revise hypothesis • Declare a new theory ☺

Sample of scientiOic investigation •  Ques!ons from exis!ng phenomena: Does parents monthly income relate with amount of smart phone that JTETI students have ?

•  Hypothesis: JTETI students with more than one smart phone have parents with monthly income more than IDR 5 million

•  Experimental inves!ga!on: -‐ Designing experiment and analysis. -‐ Defining amount of samples. -‐ Interview and ques7onnaire.

•  Analysis of experiment results: Sta7s7cal analysis, hypothesis tes7ng to check significance of the results.

•  If your results are valid, then you form new theory ☺

However…. • Not all scien7fic ques7ons can be addressed directly.

• Doing na7onal-‐scale research is paying large-‐scale curiosity. It’s expensive…. Our government some7me doesn’t want to pay curiosity. (Beeer buying Malaysian technology instead of researching new car technology ? Don’t know, ask yourself ☺).

• Some researches touch morality.

•  Real-‐world examples

ScientiOic simulation It’s a big deal ☺

Computational science in US

•  I had a nice chance to visit Museum of Science and Industry in Chicago, US, during summer vaca7on in 2014.

•  It was a nice experience for me. The museum was built in 1898. Now, it is the greatest place in US to study science. It’s just like “Taman Pintar Yogyakarta”, but 50 years later from now ☺

•  Concept of museum: remember the past, evalua7ng the present, and inven7ng the future.

Why computational science is importance ?

•  Computa7onal science and high-‐performance compu7ng could be integral to innova7ons in all of the sciences (biological/ biomedical, physical, and social), engineering, industry, and defense. (“Computa7onal Science: Ensuring America’s Compe7veness” by US President’s Informa7on Technology Advisory Commieee in 2005)

•  Computa7onal science also helps explaining science in very intui7ve way. Your children will not start from zero to advance the future of science and technology

Take home messages •  Science is a process of inves7ga7ng physical and natural world according to rules that are agreed to by scien7sts

•  Understanding proper scien7fic method is important to classify: which is “scien7fic inves7ga7on” and “non-‐scien7fic inves7ga7on”.

•  Scien7fic simula7on is a computa7onal support of scien7fic inves7ga7on.

•  Computa7onal science is interdisciplinary. It is intersec7on of science, computer science, and applied mathema7cs.

•  Studying computa7onal science is important to shape our mindset and inven7ng our future. All scien7sts have to struggle for “computer science literacy”.
