WebExhibits covers a wide variety of topics, and most take a

multidisciplinary approach that provides something for everyone.

Whether you’re looking for a quick answer to a specific question (such as, When does Daylight Saving Time start this year?) or want to delve deeply into a topic (such as, How can I learn to write obscure forms of ancient poetry?), you’re likely to discover something new—and embark on a fun, exploratory journey in the process.

Causes of Colors: Shedding light on the age-old question, "Why is the sky blue?", this exhibit also enables visitors to explore the scientific origins of color, including the relevance of vibrations, gas excitations, diffraction, and energy bands.

Color Vision and Art: Exploring the relationships between modern art and the science of color and human vision, this exhibit uses artwork and its historical context to explain what we see and why we see it in a certain way. Other topics include color interactions, peripheral vision, luminance, and equiluminance.

Calendars through the Ages: Calendars may seem mundane, but they have a fascinating backstory. This exhibit explores the rich histories of a variety of calendars, the mathematics behind calculating days, weeks, months, and years, and why we organize our lives in accordance with the sun and the moon.

Daylight Saving Time: While the adoption of Daylight Saving Time is almost always rife with controversy, most of the world has implemented it. This exhibit explores the standardization of time and the origins of Daylight Saving Time, while providing up-to-date information on if and when countries around the globe observe it.

Poetry through the Ages: Tracing the origins of European poetry from its ancient Greek roots and its evolution through history to modern times, this exhibit is designed to move poetry into the mainstream.

Investigating Bellini’s Feast of the Gods: Early in the 16th century, Giovanni Bellini painted the Italian Renaissance masterpiece The Feast of the Gods. However, ten years later, the renowned Titian painted over the masterpiece. Using IDEA’s innovative data display techniques, this exhibit explains the scientific analyses conducted by the National Gallery of Art. (A version of the exhibit was produced in Spanish for the Prado in Madrid.)

Van Gogh’s Letters: On December 13, 1872, Vincent van Gogh (1853-1890) wrote to his brother Theo, "...We must be sure to write to each other regularly..." Over the next two decades, hundreds of letters were shared between the brothers and with others, giving us an unparalleled record of the artist’s creative and spiritual life.

Pigments Through the Ages: Explore the historical origins and the science of color pigments, in rich detail and with the aid of beautiful, interactive imagery, while being treated to an interactive explanation of how paintings are created using myriad colors and types of paint.
