Integrals: Crash Course Physics #3

Continuing with last week's introduction of calculus, Shini leads us through the ways that integrals can help us figure out things like distance when we have several other key bits of information. Say, for instance, you wanted to know how far your window was off the ground. By using integrals, a tennis ball, and a stop watch, you can figure that out! It's all here in this episode of Crash Course Physics!

Rhythm and Meter in English Poetry

English poetry employs five basic rhythms of varying stressed (/) and unstressed (x) syllables. The meters are iambs, trochees, spondees, anapests and dactyls. In this document the stressed syllables are marked in boldface type rather than the tradition al "/" and "x." Each unit of rhythm is called a "foot" of poetry. The meters with two-syllable feet are - IAMBIC (x /) : That timeof yearthoumaystin mebehold - TROCHAIC (/ x): Tellmenotin mournful numbers - SPONDAIC (/ /): Break, break, break/ On thy coldgraystones, O Sea! - ANAPESTIC (x x/): And thesoundof a voicethat is still - DACTYLIC (/ x x): Thisis the forest primeval, the murmuring pinesand the hemlock (a trochee replaces the final dactyl)

Sound: Crash Course Physics #18

We learn a lot about our surroundings thanks to sound. But... what is it exactly? Sound, that is. What is sound? And how does it travel? And what is this Doppler Effect that we've heard so much about? In this episode of Crash Course Physics, Shini goes over some of the basics (and some of the not so basics) of the Physics of Sound.
