Albert Einstein

Calling all budding geniuses! Don't let inertia stop you from learning these words related to physicist Albert Einstein and his work. Best known for developing the theory of relativity, Einstein is widely considered to be one of the greatest scientists of all time. If these words give you the momentum to learn more about physics, you can practice our introductory physics list here.

Activities for this list:

definitions & notes only words
  1. relativity
    the theory that space and time are not absolute concepts
    In the early 20th century, Albert Einstein’s new and controversial theory of relativity predicted that gravity would cause light to bend.New York Times (Aug 18, 2017)
  2. energy
    the capacity of a physical system to do work
    His famous E = mc2 revealed a vast asymmetry in the cosmic relationship between matter and energy.New York Times (May 22, 2017)
  3. theory
    a well-substantiated explanation of some aspect of the world
    Albert Einstein’s theory of general relativity was still being met with skepticism.Time (Aug 9, 2017)
  4. mass
    the property of a body that causes it to have weight
    In a book on special relativity, you might expect to meet Einstein's mass–energy equivalence, E = mc2, close to the beginning.Nature (Sep 19, 2017)
  5. physics
    the science of matter and energy and their interactions
    Einstein's work laid the foundation for modern physics and cosmology, providing a perspective of space and time that is shaped by gravity.Reuters (Jun 7, 2017)
  6. physicist
    a scientist trained in the science of matter and energy
    In the 1920s, while living in Berlin, the physicist collaborated with Hungarian graduate assistant Leo Szilárd to develop and patent an energy-efficient fridge.National Geographic (Jun 20, 2017)
  7. inertia
    the tendency of something to stay in rest or motion
    Mass can be considered as a measure of inertia, or resistance to motion.US News (Dec 19, 2011)
  8. quantum
    the smallest discrete quantity of some physical property
    He says it confirms that gravity interacts with quantum fields in the manner indicated by Einstein’s theories of relativity.Nature (Jul 19, 2017)
  9. equation
    a mathematical statement that two expressions are the same
    Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2.National Geographic (Jun 20, 2017)
  10. pacifism
    the belief that all disputes can be settled by arbitration
    And then there are the fleeting references to Einstein’s outspoken pacifism, anti-fascism and support for civil rights — which put him under FBI scrutiny.Seattle Times (Sep 26, 2017)
  11. refugee
    an exile who flees for safety
    This letter shows that Einstein also lobbied on behalf of the larger group of refugees, leveraging his public profile to ask the Roosevelts to work harder to overcome red tape and quotas that impeded emigration. – Slate (Dec 13, 2013)
  12. theoretical
    concerned with hypotheses and not practical considerations
    Finding a particle-based description of gravity has obsessed theoretical physicists since Einstein.Nature (Sep 27, 2016)
  13. genius
    someone who has exceptional intellectual ability
    Albert Einstein is widely regarded as a genius, but how did he get that way?Washington Post (Nov 26, 2012)
  14. gravitational
    of or relating to or caused by gravitation
    Under this theory, big gravitational masses like stars and planets warp the fabric of space-time, bending light as it travels through the universe.Time (Aug 9, 2017)
