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%
NB: You should aeend least 80% of lectures (12 of 14 lectures) to join final exam (UAS).
QUESTION ?
Outlines
• Introduc7on • General informa7on
• Academic honesty
• Scien7fic method
• Computa7onal science
• Real-‐world examples in Japan and US (my personal experience)
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.

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”.
