These two aspects of a particle are impossible to know at the same time.
What are position and momentum?
100
Schrodinger's cat was both alive and dead in the box, which means it was in this state.
What is superposition?
100
This is the measure of an object's ability to change its own motion or the motion of another object.
What is energy?
100
Niels Bohr spent a lot of time arguing with this person, who invented the theory of relativity.
Who is Albert Einstein?
200
This factor changed the results of the slit experiment.
What is observation?
200
This idea describes uncertainty as the act of measurement changing the state of a system.
What is the semiclassical argument?
200
Using this, one can show both the existence of superposition states and the effects of measurement.
What is the polarization of light?
200
The process in which a tiny fraction of particles simply pass through barriers as if they weren't there.
What is tunneling?
200
Positrons, which have the same mass and opposite charge as electrons, are an example of this type of particle.
What is an antimatter particle?
300
This occurs when two waves are in phase.
What is constructive interference?
300
This is the point at which everything is motionless.
What is absolute zero?
300
Wave functions, probability, measurement, and this make up the four fundamental principles of quantum mechanics.
What are allowed states?
300
This device uses electron tunneling to make images of objects as small as a single atom.
What is a scanning tunneling microscope?
300
These diagrams represent complex calculations that show what happens when particles interact.
What are Feynman diagrams?
400
These are released when light shines on a piece of metal.
What are electrons?
400
This is the reason why the current position of a particle cannot be fully determined.
What is a particle's wave property?
400
DAILY DOUBLE: This mathematical formula governs the behavior of wave functions.
What is Schrodinger's equation?
400
The probability of tunneling decreases exponentially as this increases.
What is thickness of the barrier?
400
This theory describes the interaction between light and matter at the most fundamental level.
What is quantum electrodynamics?
500
This number is also known as h.
What is Planck's Constant?
500
This person proposed the theory of allowed states.
Who is Niels Bohr?
500
This experiment which "encapsulates everything that's strange about single-particle quantum physics" is actually a variation on Young's double slit experiment.
What is the quantum eraser experiment?
500
This company invented the scanning tunneling microscope.
What is IBM?
500
This argument, which derives its name from the initials of the three men who created it, argues for the incompleteness of the current quantum theory.
