Today I learn that types of ceramic pottery include earthenware, stoneware, and porcelain. These are fired at increasingly higher temperatures. Earthenware is porous and so is often glazed.

Also, Capella is the brightest star in the constellation Auriga.

Today I learn that Tamil, Telugu, Malayalam and Kannada are Dravidian languages – even though they all use different writing scripts.

I learnt that if an automaton with exactly n states accepts all strings of length n or less, then it accepts all strings.

I have just learnt that the world's largest flower is the Rafflesia arnoldii, a parasitic plant that grows in the rainforests of Indonesia.

Yup, that's my country.

Today I learned that a nickel is a tenth of a dollar and a dime is a twentieth of a dollar.
