The classrooms at Harvard, Princeton, Stanford, Cambridge, MIT, and many other great universities and scientific institutions still use chalkboards for teaching and learning. In this story, I shall share the 10 most brilliant physicists and mathematicians captured with their iconic chalkboards.

Do any schools still use chalkboards?

Chalkboards in classrooms are accessible for many parts of the world, teach good penmanship, and many find the contrast of chalk on chalkboards to be more visually appealing than whiteboards. The answer to “Are chalkboards still used in schools today?” is yes.

Why the World’s Best Mathematicians Are Hoarding Chalk

Why does Harvard use chalkboards?

Chalkboards are a lot nicer for drawing details. Chalk allows you to color in things quickly, draw dotted lines (I suggest watching Walter Lewin lectures on OCW), and write things with varying intensity. It's also easier to draw things with thicker lines (using bigger pieces of chalk).

Why do Stanford math professors still use chalk?

The more spacious chalkboard versus the limited screen size, Conrad said, is conducive to students' learning as they can constantly go back and forth on mathematical derivations. The layout in Room 380C of Sloan Hall, for instance, has two levels of chalkboards, which allow for enhanced flexibility.

Are chalkboards unhealthy?

Some potential risks associated with chalk dust exposure include: Respiratory issues: Inhaling chalk dust can cause irritation to the respiratory system, leading to coughing, sneezing, and potentially triggering asthma attacks in those with pre-existing conditions.

If you are deciding between chalkboards and whiteboards for design or art, chalkboards are the way to go. Although markers for dry erase board sheets and surfaces come in a wide variety of colors, they aren't as useful when it comes to coloring or shading.

Do mathematicians prefer chalk?

Even in today's day and age, many great universities prefer using chalkboards. If you ask some prolific mathematicians and physicists all across the world about what they prefer more, I'm pretty sure most of them will say chalkboards.

Why are chalkboards green?

By the 1960s, the green chalkboard trend was in full swing. Teachers had discovered that a different colored paint was a lot more comfortable to stare at all day, because green porcelain paint cut down on glare. By and large, many blackboards were slowly replaced by their green brethren.
