General background information

By this point in the course, you should have learned enough that you can put Java OOP to work in a substantive way. In this course, which is designedspecifically for blind students, you will write substantive programs that deal with something that you are probably very good at -- sound.

An earlier module explained some of the physical aspects of sound. It also explained a little about how you can write programs to create sound with acomputer.

This module will show you how to write a Java OOP program that uses a random number generator to produce white noise .

what about nanotechnology for water purification
RAW Reply
please someone correct me if I'm wrong but I think one can use nanoparticles, specially silver nanoparticles for water treatment.
Damian
yes that's correct

I think

Nasa has use it in the 60's, copper as water purification in the moon travel.

is there industrial application of fullrenes. What is the method to prepare fullrene on large scale.?
Rafiq
industrial application...? mmm I think on the medical side as drug carrier, but you should go deeper on your research, I may be wrong
