Uranus in the third house makes the mind fast, original, independent and poorly tolerant of templates. The person may learn unusually, speak unusually, argue with authorities, invent their own memory methods, easily grasp languages or technical principles, but feel bored in a standard education system.
In a strong expression this is inventive intelligence, a technical mind, charisma of speech and a nonstandard approach to study, media, politics, journalism, the internet, languages, astrology, Tarot, palmistry and new ways of transmitting information. The person may be a prodigy, left-handed, bilingual or an orator with an unusual manner.
