Inverted bell
The inverted bell is a metaphorical name for geometric shape that resembles a bell upside-down. (Wikipedia).
The inverted bell is a metaphorical name for geometric shape that resembles a bell upside-down. (Wikipedia).
A physical pendulum finds stability in its inverted position when driven at the proper frequency and amplitude combination. The physical pendulum seen here is mounted on a ball-bearing pivot and can rotate 360 degrees; the pivot is driven at about 50 Hz with an amplitude of about 1 cm (3/

Bell Labs Wave Machine: Standing Waves
Standing waves are created on the Bell Labs apparatus. The apparatus is "open" at both ends, therefore the number of nodes is equal to the number of overtones. For example, the fourth harmonic will have four nodes, the fifth harmonic will have five nodes, etc.

Bell Labes Wave Machine: Mismatched Impedence
Two segments of the Bell Labs apparatus are connected. The segments have different impedance. When a pulse travels from high impedance to low impedance, it is reflected with positive polarity and transmitted with positive polarity. When a pulse travels from low impedance to high impedance,

ENCAD CADJET 2 Printer: Equipment Autopsy #75
http://thegeekgroup.org/ - We're farming for parts, which means you get an autopsy out of the deal! Looking for a setup for an inverted pendulum, Chris dismantles a rather large Kodak printer. Along the way we learn about extrusion, bell-cranks, the brains of the setup, and more! Video Li

det(AB) = det(A) det(B) In this video, I show why det(AB) = det(A) det(B). This video really illustrates why linear algebra is so neat. No messy calculations are required, just some useful facts about row reduction! Determinants and Row Reduction: https://youtu.be/pjxGgCcGwFY Elementary

Writing Vectors in a New Coordinate System **Example**
The best method to algebraically express a vector in some given coordinate system (ie in terms of a given basis) is by introducing a matrix whose columns are the basis vectors, and then inverting that. We pick up some new notation along the way. ******************************************
