General knowledge
Science: heat travels in three ways: conduction (through solids), convection (through liquids and gases) and radiation (without a medium, as from the sun).
विज्ञान में ऊष्मा तीन तरीकों से चलती है: conduction (ठोस से), convection (तरल और गैस से) और radiation (बिना माध्यम के, जैसे सूर्य से)।
Radiation therapy (radiotherapy) treats cancer; Marie Curie studied radioactivity and won two Nobel Prizes; the ozone layer protects the earth from ultraviolet (UV) radiation.
Radiation therapy (radiotherapy) कैंसर का इलाज करती है; Marie Curie ने radioactivity का अध्ययन किया और दो नोबेल पुरस्कार जीते; ओज़ोन परत पृथ्वी को पराबैंगनी (UV) विकिरण से बचाती है।
