Polymer isotactic polypropylene vs atactic polypropylene question: In 1963, Karl Ziegler and Giulio Natta received the Nobel prize in chemistry for the development of a process that could be used to produce (among other things) linear, unbranched, isotactic polypropylene. Why was this an important development? What useful properties does isotactic polypropylene have when compared to atactic polypropylene? Describe some applications where isotactic polypropylene could be used, where it would be impractical to use atactic polypropylene. Include drawings that illustrate the...

Mach's principle says that it is impossible to tell if something is accelerating unless there is something else in the universe to compare that motion to, which seems reasonable. However, if you had one detector in the universe, you seem to be able to tell if it is accelerating because an accelerating detector would record radiation where a non-accelerating detector would not, due to the Unruh effect. So, my question is, does the Unruh effect provide a way to tell...
