  1. 8. a theoretical framework in which the point-like particles of particle physics are replaced by one-dimensional objects called strings.
  2. 9. the force that holds particles together in the atomic nucleus and the force that holds quarks together in elementary particles.
  3. 10. A physical entity postulated in string theory and related subjects.
  4. 11. The projection of the particle spin along its momentum direction.
  5. 12. A part of mathematics that studies the size, shapes, positions and dimensions of things.
  6. 13. a physical quantity is the index of each of the fundamental quantity ( Length, mass, time, temperature, Luminous intensity, Current ) which expresses that quantity.
  7. 15. the interaction of electric currents or fields and magnetic fields.
  8. 17. one of the fundamental particles in physics
  9. 18. Theory that explains how space and time are linked for objects that are moving at a consistent speed in a straight line.
  10. 19. fundamental force that acts between leptons and is involved in the decay of hadrons.

  1. 1. a branch of physics that describes how the Universe works at the level smaller than atoms.
  2. 2. a theory trying to unify the four known natural forces or fields
  3. 3. The domain of physical size that encompasses objects smaller than an atom.
  4. 4. largest and most powerful particle accelerator.
  5. 5. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
  6. 6. a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena.
  7. 7. A branch of physics that studies the nature of the particles that constitute matter and radiation.(high energy physics)
  8. 10. An idea that history repeats itself to solve similar problems.
  9. 14. periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.
  10. 16. co-founder of string field theory
