Any decent textbook on astrophysics starts with a historical prologue running something like this: "Once upon a time, we believed the earth was flat. We were wrong. Once upon a time, we believed the sun rotated around the earth. We were wrong."

Additionally, applications developed in this manner perform well across many browsers (even lynx) and with assistive technologies for the disabled.
