What is the primary focus of quantum physics?
Click to flip
Quantum physics studies the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles.
Click to flip
Name the principle that states particles can exist in multiple states simultaneously.
Click to flip
The principle is called superposition.
Click to flip
What is the uncertainty principle?
Click to flip
The uncertainty principle, formulated by Heisenberg, states that the position and momentum of a particle cannot both be precisely measured at the same time.
Click to flip
What is a fundamental idea about energy introduced in quantum mechanics?
Click to flip
Quantum mechanics introduces the idea that energy is quantized, which means it comes in discrete amounts called quanta.

What do dimensions in string theory refer to?
Click to flip
In string theory, dimensions refer to the different directions in which strings can vibrate, beyond the three spatial dimensions and one time dimension we experience daily.
Click to flip
How many dimensions are predicted by string theory?
Click to flip
String theory predicts 10 or 11 dimensions, depending on the specific version.
Click to flip
Why are extra dimensions necessary in string theory?
Click to flip
Extra dimensions are required for mathematical consistency in string theory and allow strings to vibrate in ways that can replicate the variety of particles we observe.
Click to flip
What is the main difference between string theory and the standard model?
Click to flip
The main difference is that the standard model describes particles as point-like, while string theory describes them as vibrating strings.
Click to flip
What is a string in string theory?
Click to flip
A string is a fundamental, one-dimensional object whose different vibrational states correspond to different particles.
Click to flip
How does string theory attempt to unify the fundamental forces?
Click to flip
String theory aims to unify gravitational, electromagnetic, weak nuclear, and strong nuclear forces by describing them as manifestations of vibrating strings.
Click to flip
What is the significance of Planck length in string theory?
Click to flip
The Planck length is considered the scale at which classical notions of gravity and space-time break down, where string effects become significant.
Click to flip
What does string theory propose about space-time?
Click to flip
String theory proposes that space-time is a dynamic entity made from fundamental strings, and may have more dimensions than we can perceive.
Click to flip
Can string theory be directly tested with current technology?
Click to flip
No, string theory currently cannot be directly tested with existing experimental technology.
Click to flip
How does string theory differ in its treatment of particles compared to classical physics?
Click to flip
Classical physics treats particles as point-like with well-defined properties, while string theory models them as dynamic, one-dimensional strings.
Click to flip
What is the significance of the term 'string' in string theory?
Click to flip
The term 'string' refers to the fundamental one-dimensional objects that replace point particles in string theory.
Click to flip
How do strings differ in closed and open string theories?
Click to flip
In closed string theories, strings form closed loops, while in open string theories, strings have endpoints.
Click to flip
What is the role of symmetry in the standard model?
Click to flip
Symmetry in the standard model plays a crucial role in unifying electromagnetic, weak, and strong forces through mathematical frameworks.
Click to flip
Why is string theory considered a candidate for the theory of everything?
Click to flip
String theory is considered a candidate for the theory of everything because it attempts to unify all fundamental forces and particles into a single framework.
Click to flip
What challenge does string theory face in terms of predictability?
Click to flip
String theory faces the challenge of predictability because it leads to a vast landscape of possible solutions, making it difficult to generate unique predictions.
Click to flip
What is one way string theorists attempt to reconcile extra dimensions with our observable universe?
Click to flip
String theorists propose that extra dimensions are compactified or curled up at scales too small to be observed with current technology.
