 "What I then saw confounded and amazed me..."
"Looking upwards I surveyed the ceiling of my prison. It was some thirty or forty feet overhead...In one of its panels a very singular figure of Time as he is commonly represented, save that, in lieu of a scythe, he held what, at a casual glance, I supposed to be the pictured image of a huge pendulum, such as we see on antique clocks...I fancied I saw it in motion.""I saw that some ten or twelve vibrations would bring the steel in actual contact with my robe- and with this observation there suddenly came over my spirit all the keen, collected, calmness, of despair."How long will this despair last? Does Poe provide sufficient information for you to explore a range of values for the period of this pendulum? Use this form to explore the differences between a simple pendulum and a physical pendulum, and the effects of the "small angle approximation."
