"In contrast to the environmentally harmful solvent dichloromethane used in Experiment 2, the only solvent used in this experiment is dihydrogen oxide (H2O), also known as water. It has been established that H2O can cause serious injury or death by inhalation (in its liquid state), thermal burns (in its gaseous state), and hypothermia (in its solid state). Nevertheless, H2O is not officially classified as a hazardous chemical and may be released into the environment."

"However, as we consider larger and more complex objects, there must come a point at which we are no longer justified in considering the wave nature of an object. At that point, we are back in our familiar nonquantum world, with the physics of earlier chapters of this book. In short, an electron is a matter wave and can undergo interference with itself, but a cat is not a matter wave and cannot undergo interference with itself (which must be a relief to cats)."

As captioned in my textbook:

"An overhead view of a frog that is being levitated in a magnetic field produced by current in a vertical solenoid below the frog. (The frog is not in discomfort; the sensation is like floating in water, which frogs like very much.)

( Because not everything has to be exams and final projects, gee dee ai. Sometimes there are frogs. )
