## BIG IDEAS
- Starts at the beginning of the 20th century
- Two revolutionary theories
## Modern Physics
- Two revolutionary theories
- [[Notes Vault/Physics Notes Vault/Relativity/Relativity|relativity]]
- [[Albert Einstein]] (1905) stated space, time, and speed are not absolute.
- measured length of an object traveling at high speeds is shorter.
- time depends on the motion of the observer.
- time dilation
- gravity can affect time and space
- quantum mechanics deals with subatomic particles
- atoms are the smallest unit of matter.
- atoms are constructed of smaller particles.
- particle accelerators, study subatomic particles traveling at high speeds
- discovery of Higgs-Boson particle
- gives matter the property of mass.
- relativistic quantum mechanics, attempt to marge relativity and quantum mechanics.
