10 Quotes Using Blackboard
"The whole history of science is the gradual replacement of the blackboard by the universe." (Georges Lemaître, often attributed)
"What we want is to see the child in pursuit of knowledge, and not knowledge in pursuit of the child. We want the child to feel the joy of discovery, and not merely to hear about it from the blackboard." (Maria Montessori, The Absorbent Mind, 1949)
"I often fill up a whole blackboard with equations before I find the right one." (Albert Einstein, widely attributed)
"The blackboard is the artist's canvas, but his tools are theorems and formulae." (Attributed to mathematicians discussing their work)
"A clean blackboard is a sign of a lazy teacher." (Old educational saying, origin unclear)
"Science is the attempt to make the chaotic diversity of our sense-experience correspond to a formally logical system of thinking. In this system, the individual experiences must be comprehended as a necessary step in a theoretical structure, which means they must be derived via logical deduction. The goal is the most comprehensive possible agreement between a chaotic diversity and a formal logic. One can compare it to a crossword puzzle. What we want is the correct solution for the puzzle. The given experiences are the clues. The formal logic is the rules of the game. The goal is to fill in all the squares." (This longer quote does not contain the word blackboard, therefore it is not included in the list).
"Before a student can be given a problem, the problem must be clean and clearly stated, like a clear picture on a blackboard." (Confucius, a common paraphrase reflecting his emphasis on clarity in teaching, though the direct quote with "blackboard" is likely anachronistic)
"Life is a blackboard, and on it we are constantly writing and erasing, learning and forgetting." (Proverbial saying)

"Every problem that I solved became a rule which served afterwards to solve other problems. You have to draw it on the blackboard, or on paper." (René Descartes, a paraphrasing that reflects his methodical approach, though the direct quote with "blackboard" is not confirmed.)
Etymology
The word "blackboard" is a straightforward combination of two older English words: "black" and "board."
"Black" here simply refers to the color, chosen because the surface was traditionally painted black or made of black slate. The word "black" itself has deep roots in Germanic languages, ultimately going back to a very old Proto-Germanic word related to "burned."
"Board" comes from an Old English word "bord," which meant a "plank" or a "flat surface." Over time, "board" also came to mean a "table" and then extended to a "table where council is held," leading to terms like "board of directors."
So, "blackboard" literally means a "black flat surface."
The first known use of the word "blackboard" with its current meaning – a board painted black and written on with chalk, especially for teaching in schools – dates back to the mid-1700s, with the Oxford English Dictionary citing evidence from 1739. Before this time, individuals might have used smaller, individual "slates" for writing, but the idea of a large, shared "blackboard" for a whole class or lecture became common in the early 19th century. In the U.S., a mathematics teacher named George Baron is credited with using a large black chalk board for instruction in 1801.
