Scientific apparatus and instruments; Santa Clara University (Calif.); Simple machines; Archimedean screw
A simple mechanical device credited to Archimedes. When the lower end of the screw is placed in water, turning the device raises water to the top. This principle has various applications for drainage and irrigation, but the instrument can also be...

Scientific apparatus and instruments; Santa Clara University (Calif.); Camera lucida;
An artist's aid for drawing, the camera Lucida was a portable device that was used to reproduce visual images on to paper. An adjustable prism mounted on the end of a supporting arm reflects the surrounding light and produces the image onto the...

Crova's apparatus was designed for the purpose of representing vibratory movements on the screen, with 8 disks. Turning the crank past a vertical slit caused the disks to rotate, while a beam of light from the optical system impinged on the slit...
Scientific apparatus and instruments; Santa Clara University (Calif.); Galvanometer
A galvanometer is an instrument used to measure the presence, direction, and strength of small electric currents in a conductor. A magnetic needle is deflected by the presence of an electric current in a nearby conductor. The needle turns at right...

Scientific apparatus and instruments; Santa Clara University (Calif.); Electric batteries
Grenet Batteries were single-element battery sources with flasks varying in size, from 1/3 liter to 3 liters. These batteries, when filled with an acid solution and placed in series, were a common source of electrical current prior to the...

""The hydraulic press depends on Pascal's principle: The pressure throughout a closed system is constant. At one end of the system is a small area piston driven by a lever to increase the mechanical advantage. The small-diameter tubing...
Scientific apparatus and instruments; Santa Clara University (Calif.)
In this demonstration apparatus, water pours into the top section of the central rotor, pivoting freely about its axis. The two pipes projecting from the bottomof the rotor are closed at the end but with a rearward-facing hole. The rotor spins as...
