Informations

Polish orthography is the system of writing the Polish language. The language is written using the Polish alphabet, which derives from the Latin alphabet, but includes some additional letters with diacritics.: 6  The orthography is mostly phonetic, or rather phonemic—the written letters (or combinations of them) correspond in a consistent manner to the sounds, or rather the phonemes, of spoken Polish.

For detailed information about the system of phonemes, see Polish phonology.

In traditional Chinese culture, qi or ch'i ( CHEE simplified Chinese: 气; traditional Chinese: 氣; pinyin: qì qì) is believed to be a vital force forming part of any living entity. Qi translates as "air" and figuratively as "material energy", "life force", or "energy flow". Qi is the central underlying principle in Chinese traditional medicine and in Chinese martial arts.

The practice of cultivating and balancing qi is called qigong. Believers of qi describe it as a vital force, the flow of which must be unimpeded for health. Qi is a pseudoscientific, unverified concept, which has never been directly observed, and is unrelated to the concept of energy used in science (vital energy itself being an abandoned scientific notion).
