Line spectrum of a white lamp, consisting of a dark blue, light blue, green, orange (maybe?), and a red line, between approximately 430 and 600 nm. The lines appear on top of a dark wavelength scale, after bouncing off a diffraction grating.

Same setup as before, but now the compass needles re-arranged to show the circular magnetic field around a straight conductor.
Many tiny compass needles distributed on a plexiglas sheet around a conductor, though the voltage source is off, no current flowing. The compass needles are all roughly parallel, and pointing towards geographic north, verified with a standard orientation/navigation compass.
tiny step/waterfall in a stream, where the edge is smoothly rounded that it almost looks like laminar flow going over

Colpitts oscillator circuit built on a small breadboard, with an external voltage supply and an oscilloscope analysing the resonance frequency of the circuit. The display shows a nice sine curve.
Some of the electronics sets for building a colpitts oscillator, filled into baggies and labelled with the circuit scheme
