Living Library

The Living Library works exactly like a normal library - readers come and borrow a 'book’ for a limited period of time. There is only one difference: the Books in the Living Library are human beings, and the Books and readers enter into a personal dialogue. The Books in the Living Library are people representing groups frequently confronted with prejudices and stereotypes, and who are often victims of discrimination or social exclusion. In this library, Books cannot only speak, but they are able to reply to the readers' questions, and the Books can even ask questions and learn themselves.

In program i was especially invited to present an introduction to open source coded programs R and Gretl and their applications in economics. (Addition After The Presentation: The presentation and  the questions in the end were fine :))) It was a great honour for me to meet with Professor Dr. Ümit Şenesen, the head of program, and who translated "Basic of Econometrics, Damador Gujarati" with Professor Dr. Gülay Günlük Şenesen. Thanks to everyone in the organization.)

Tr.İ.T.Ü. Sosyal Bilimler Enstitüsü İktisat Programı İktisat Seminerlerine davet edildim. Seminer programı 2004 yılından beri devam ediyor. Seminer programına davet edilen akademisyenlerden iktisat alanında yaptıkları araştırmaları sunmaları isteniyor. Benden de özellikle açık kaynak kod kullanan R ve Gretl programlarının tanıtımı ve ekonomi uygulamaları hakkında bir sunum yapmam istendi. (Sunum Sonrası İlave: Sunum ve sonundaki sorular oldukça iyiydi :))) Program başkanı ve "Temel Ekonometri, Damador Gujarati" kitabını Profesör Dr. Gülay Günlük Şenesen ile birlikte çeviren Profesör Dr. Ümit Şenesen ile tanışmak benim için büyük bir onurdu. Organizasyonda emeği geçen herkese teşekkürler.)

Equations for Valentines

This Demonstration shows four different heart-shaped algebraic surfaces. You can improve the quality of the plots by increasing the "number of sample points" and "max recursion" settings but this will also increase the rendering time.
