Question 2 of 21

Quantum physics is the branch of classical physics that describes the behavior of very slow objects.

fact
fiction
almost fact: Quantum physics is not a branch of classical physics; it's a law unto itself.

... This branch of physics was developed to study subatomic particles, because they behave differently from larger ones.

Question 3 of 21

Albert Einstein, not a huge fan of quantum physics, said, "God does not play games with the universe."

fact
fiction
almost fact: He actually said, "God does not play dice with the universe."

... Einstein, who was known for saying, "God does not play dice with the universe," never quite figured out what he thought about quantum physics. It disturbed him greatly.

next

Question 4 of 21

An electron is a particle.

fact
fiction
almost fact: Sometimes it's a wave, too.

... This awareness that an object can take different forms, such as a particle and a wave, is called the Copenhagen Interpretation.

next

Question 5 of 21

The Copenhagen Interpretation was developed by Niels Bohr.

fact
fiction
almost fact: Bohr worked with Werner Heisenberg.

... Bohr and Werner Heisenberg, along with others, worked together to form this interpretation of quantum physics.

next

Question 6 of 21

The Uncertainty Principle notes that two properties of an object can't be measured simultaneously.

fact
fiction
almost fact: While this is what the principle notes, scientists disagree on the name.

... Some physicists think the Uncertainty Principle is improperly named, and that it's not a principle, but "relations."

next

Question 7 of 21

Schrodinger's Cat -- a cat in a box exposed to radiation in an amount that may or may not kill it -- is dead.

fact
fiction
almost fact: Who knows? Looking in the box would alter the reality.

... It's impossible to tell! Designed to illustrate the difficulty of determining reality, this thought problem implies that the cat is both alive and dead until we open the box.

next

Question 8 of 21

The "quantum" in quantum physics means "small."

fact
fiction
almost fact: Actually, it means "mathematical."

... Max Planck coined the term, which means "a specific amount."

next

Question 9 of 21

Time moves ahead, in a straight line.

fact
fiction
almost fact: Time moves ahead in a wave, not a line.

... In quantum physics, time is fluid and can also move backward. This discovery could eventually lead to some form of time travel.

next

Question 10 of 21

An object can exist in every possible state at the same time.

fact
fiction
almost fact: Experiments have shown that observation can change reality.

... According to some experiments, observation can change reality. This is called "superposition." When measured or observed, an object "chooses" one state.

next

Question 11 of 21

Objects are isolated from one another in the subatomic world.

fact
fiction
almost fact: It's almost as if the objects can communicate faster than the speed of light.

... Everything's interconnected in the quantum world. This is called entanglement.

next

Question 12 of 21

There are three forces that act on atoms and subatomic particles.

fact
fiction
almost fact: There are four, but we only know three of them.

... There are four: gravity, electromagnetism, the strong force (which binds particles in the atom's nucleus) and the weak force (which is responsible for radioactive/beta decay).

next

Question 13 of 21

Werner Heisenberg received the Nobel Prize for physics in 1935.

fact
fiction
almost fact: He earned the prize in 1933.

... This German physicist earned the Nobel Prize in 1932 for his work in quantum theory and nuclear physics.

next

Question 14 of 21

Physicists see a relationship between quantum physics and Eastern religion.

fact
fiction
almost fact: The relationship is with Western religion.

... Many physicists tend to agree on the relationship between quantum physics and Eastern religion, and Fritjof Capra has even written a book called "The Tao of Physics."

next

Question 15 of 21

The basic premise of string theory is that quarks and electrons are one-dimensional strings.

fact
fiction
almost fact: After that initial statement, no one agrees about much else regarding string theory.

... It's a fact! These strings move and vibrate, giving the particles their peculiar qualities.

next

Question 16 of 21

M-theory is an offshoot of string theory in which there are 11 dimensions.

fact
fiction
almost fact: There may be many, many more dimensions.

... The proposal of M-theory, in which there are 11 dimensions, led to the "second superstring revolution" in 1995.

next

Question 17 of 21

Werner Heisenberg said, "What Schrodinger writes about the visualisability of his theory is probably not quite right; in other words, it's crap."

fact
fiction
almost fact: He probably used nicer words.

... While Heisenberg did say this, Schrodinger was no fan of Heisenberg's, either.

next

Question 18 of 21

Entanglement is explained in a paper called "Bertlmann's Shoes and the Nature of Reality."

fact
fiction
almost fact: It's actually "Bertlmann's Socks and the Nature of Reality."

... It was socks! Physicist John Bell used a colleague (Dr. Bertlmann) who always wore mismatched socks as an example of conclusions that can be made about entangled particles.

next

Question 19 of 21

Star Trek-style transporters are in the final stages of development right now.

fact
fiction
almost fact: They have transported a single molecule, but even that takes a lot of time.

... These types of transporters will probably never be practical for moving complex creatures or entities.

next

Question 20 of 21

The Large Hadron Collider, located under the Swiss-Italian border, is used to seek the fundamental building blocks of the universe.

fact
fiction
almost fact: It's on the Franco-Swiss border

... Scientists hope that the Large Hadron Collider, located on the Franco-Swiss border, can prove the existence of the Higgs boson, or so-called "God particle."

next

Question 21 of 21

Quantum physics shows that the universe is stranger than we ever imagined.

fact
fiction
almost fact: What's beyond the universe is strange, too.

... Our universe is a strange place. Science-fiction writer Arthur C. Clarke observed that "any sufficiently advanced technology is indistinguishable from magic."
