Welcome to the Quantum Measurement Tutor!
Please select a measuring device from the menu and click "OK".
This is a demonstration version of the Measurement Tutor
that only allows a meter stick to be selected as the measuring device.
In the full-featured version of the Tutor all measuring devices below are activated.
If you have an actual meter stick available, it would be helpful, although not essential,
to have it with you as you use the Tutor. Start by measuring or estimating
the length of a nearby object, such as your computer screen.
