This year is set to be an eventful one for space travel and exploration. Already, we've seen SpaceX make history by becoming the Для просмотра ссылки Войди или Зарегистрируйся to ferry astronauts to the International Space Station. We're also well into the testing stages of the Для просмотра ссылки Войди или Зарегистрируйсяthat aims to make space exploration and habitation a tangible reality.

While all of these are bold initiatives, it helps to take a step back and gauge just how far we've come since our baby steps in the world of space exploration. Fermat's Library has done exactly that. The platform, which specializes in developing software to help illuminate academic papers, went through the original Apollo 11 code that was penned down by Margaret Hamilton in assembly language back in 1969 and Для просмотра ссылки Войди или Зарегистрируйся

Specifically, the team annotated the Для просмотра ссылки Войди или Зарегистрируйся file for calculating transcendental functions like sine and cosine that were a linchpin for Apollo 11's voyage to the Moon.

Fermat's Library uploaded its Для просмотра ссылки Войди или Зарегистрируйся, an online repository that it has curated for academics and enthusiasts to annotate papers with LaTeX and Markdown scripts. The excerpt below shows the computer's approximation of calculates cos() in the SPCOS subroutine.
