This may sound a bit odd, but

In the last lecture, we began looking at the programming This lecture nguage Scheme. with the intent of learning how that anguage would provide a basis for describing procedures and Adding procedures and procedural abstractions

Slide l.l.1 This first thing we need to do is discuss the focus of 6.001 What is this course all about? This seems quite obvious-- this What is the focus of 6.001 is a course about computer science. But we are going to claim This course is about Computer Science in a rather strange way that this is not really true

Question No. 1 A liquid Ni-Al alloy sphere is levitated with an induction coil in an excellent vacuum chamber at 500 C. Stirring of the droplet is intense so that the melt composition is uniform at any time. If the sphere has a radius of one cm and an initial Al mole fraction of 1%. Derive an expression which
