Sorry for the delay between posts. Here in Virtuosi-land, we've all begun our summer research projects and I think we've just become a little bogged down in the rush that is starting a summer research project. You feel as though you have no idea what the heck is going on, and just try desperately to keep your head up as you hit the ground running, but thats a topic for another post.
In this post I'd like to address a fun physics problem.
How long can you balance a pencil on its tip? I mean in a perfect world, how long?
No really. Think about it a second. Try and come up with an answer before your proceed.
What this question will become by the end of this post is something like the following:
Given that Quantum Mechanics exists, what is the longest time you could conceivably balance a pencil, even in principle?
I will walk you through my approach to answering this question. I think it is a good problem to illustrate how to solve non-trivial physics problems.
I will try and go into some detail about how I arrived at my solution. For most of you this will probably be quite boring, so feel free to skip ahead to the last section for some numbers and plots.
