Discover your passion and your gifts!

Do not worry about forgetting the answers

Escher 1898-1972

De-familiarize

“If we start to examine the general laws of perception, we see that as perception becomes habitual, it becomes automatic”

Defamiliarize

“The purpose of art is to impart the sensation of things as they are perceived and not as they are known”

The purpose of IST4 is to impart the sensation of ideas as they are conceived and not as they are known

Defamiliarize

How? Teach about the historical innovation process

and the related inventors

Make the subject of Information and Logic

unfamiliar...

Q: Generate any binary string from 01 only with tandem duplications? Yes

The target string has to start with 0 and end with 1

Proof: We have an algorithm! Generate the 01 blocks and then extend the 0s and 1s

Also: It is true if the duplication length is either 1 or 2.

Organization and Policy

Class Policy

Homework sets: There are 5 homework sets; all weighted equally. The total weight of the 5 homework set is 94 points

There is no midterm and no final

Essays: There are two essays, 3 points each A selected set of students are given the opportunity to present their essay in class (3 points)

However, to be eligible to receive credit for quizzes/ essays / presentations/ extra credit, a student has to fully attend at least 16 lectures (out of 20), must attend the last two lectures (at least 14+2)

Quizzes: There are 5 in-class pop quizzes, for a total credit of 2 points

Class Policy Attendance When you attend a class, you should write your initial next to your name on the attendance list provided by the TAs Final Grade The final grade is calculated based on the grades of the homeworks and the quizzes / essays / presentations (if the student is eligible) and will be converted to a letter grade:

94+2+3+3+3

Class Policy

Collaboration and Open-Book policy Collaboration, in the sense of discussing how to solve the homework problems, is allowed on some, but not all, homework problems. Every homework problem includes a specific statement whether collaboration is allowed or not For all homeworks: •  Write the final solutions of the homeworks alone and understand them fully •  Books, papers, notes can be consulted, but not copied from •  The use of solutions from previous years is not allowed

Class Policy - Homeworks •  Homeworks are to be submitted in class They are due at the start of class on the due date

•  A late homework submission should include only solutions to problems that were not attempted in the previous (on-time) submission •  We are human... and occasionally make mistakes in grading; corrections of grades should be requested within a week from the time the graded homeworks were returned

•  Late homeworks lose 20% of their value immediately and lose 100% of their value a week after the due date except in institute-established cases of illness or emergency

•  Homeworks are returned in class. Keep your graded sets until you get the final grade. That’s your record

There is no Text Reference Books

• The reference books are recommended as sources for extending your knowledge beyond what is covered in class • They are not a required reading

• The list is posted on the class web site • The books are reserved at the Caltech library (SFL)
