This DIY conversion stand is more than capable of functioning in an actual laboratory setting. With magnification levels as high as 175x, plant cells and their nuclei are easily observed! In addition to allowing the observation of cells, this setup also produces stunning macro photography.
The cdza music team is at it again with the second episode of their series The Instrumentals: Intro to Drums. After introducing the drum set, drummer Allan Mednard compares and contrasts two kinds of rhythms: rock and jazz.
