“Many physicists like to do a back-of-the-envelope calculation before delving deeper into a computation, and blackboards are a great tool for that”, says Tibra Ali, another theorist at the Perimeter Institute. Indeed, there's a trophy-like quality to a clever piece of work prominently displayed on a blackboard.Jun 1, 2017
Albert Einstein gave a series of lectures at Oxford University in the 1930s. In a BBC series looking at the "wonders" of Oxford's museums, Stephen Johnston from the Museum of the History of Science shows us the blackboard he used.

In many fields of science and investigation, blackboards have been replaced with whiteboards or slide show presentations. But chalk is cheaper and biodegradable. It smells better than whiteboard markers and is easier to clean up, mathematicians say. It is also more fun to write with.Sep 24, 2019
Lectures, blackboards and language barriers Einstein stayed in Oxford until 27 May 1931, giving three lectures. The first took place on Saturday 9 May at Rhodes House to an overflowing audience made up of university staff, their companions and 500 students picked from a wide range of disciplines, not just science.Jun 17, 2019
Albert Einstein made three visits to Oxford between 1931 and 1933, staying for a month in the spring of each year. For our understanding of Einstein's work, the Rhodes Memorial Lectures that he delivered during his first visit are of special interest.May 9, 2018

160Albert Einstein's IQ is generally referred to as being 160, which is only a gauge; it's impossible that he at any point took an IQ test during his lifetime. Here are 10 people who have higher IQs than Albert Einstein.May 27, 2021
If you're still wondering whether are chalkboards still used in schools or not, your answer is yes, they are. While interactive whiteboards and regular whiteboards continue to take over many new classrooms, it's also easy to see why so many educators are reluctant to give up their chalkboards.
A blackboard (also known as a chalkboard) is a reusable writing surface on which text or drawings are made with sticks of calcium sulphate or calcium carbonate, known, when used for this purpose, as chalk. Blackboards were originally made of smooth, thin sheets of black or dark grey slate stone.
Readability and Contrast The contrast of black on white improves comprehension when reading quickly or skimming text. Most people can read black on white up to 32% quicker than reading white on black text. By using dry erase board sheets over blackboard sheets, you can improve contrast and readability when using it.Oct 2, 2019
