14 січня. Всесвітній день логіки

День логіки започатковано у 2019 році під егідою ЮНЕСКО, щоб привернути увагу до важливості критичного мислення. Ця дата відзначає день народження Альфреда Тарського, видатного логіка та математика. Критичне мислення треба розвивати, бо в сучасному світі — це дуже корисне вміння. 

Слово дня: “ДУМКА" -  те, що з'явилося в результаті міркування, продукт мислення.

Кожна думка має значення, якщо підкріплена логікою.

The word of the day:  riddle (noun)/ˈrɪdl/

Meaning: a question or statement that requires careful thought to answer or solve.

Example: The Sphinx posed a famous riddle to those seeking entry to the city.

Your MINI-TASK is to look through the riddles, solve them and share your answers in the chat.
