Mindblown: a blog about philosophy.

  • Refugee

    A person fleeing danger or distress, especially in times of war or political persecution.  

  • Refuge

    A shelter; a safe place for persons fleeing danger or distress.  

  • Refresh

    To restore strength; to relieve from fatigue; to renew; to revive.  

  • Refractory cytopenia with multilineage dysplasia

    In the World Health Organization classification of myelodysplastic syndromes, a disorder in which two or more blood cell lines form aberrantly. For example, the peripheral blood shows evidence of anemia and leukopenia, or of anemia, leukopenia, and thrombocytopenia; and the bone marrow shows abnormal precursors in two or more mature blood cell precursors.  

  • Refractivity

    The quality of being refractive; the ability to refract.  

  • Refractive power

    The degree to which a transparent body deflects a ray of light from a straight path.  

  • Refractive media

    The structures of the eye that deflect light: the cornea, aqueous, crystalline lens, and vitreous.  

  • Refractionist

    A person skilled in determining and correcting ocular refractive errors.  

  • Static refraction

    Refraction of the eye when accommodation is at rest or paralyzed.  

  • Index of refraction

    The ratio of the angle made by the incident ray with the perpendicular (angle of incidence) to that made by the emergent ray (angle of refraction). A fixed numerical value associated with a particular material and specific color of light, indicating the extent of light refraction induced by that material, is known as the refractive…
