Are Newton's three laws all that was needed for the science that got us to the moon? Or did we need Einstein's theories to get there? I just started studying physics last week, so forgive me for my baseness.

What I think Russ is getting at is that Newton's "three" laws alone do not say much about gravity.AndrewRibeiro said:Is this like telling a freshman there's a pool on the roof?
Yep. There was a slight disconnect in your OP, where you are clearly implying gravity by mentioning relativity, but gravity is a different law from the three laws of motion.jbriggs444 said:What I think Russ is getting at is that Newton's "three" laws alone do not say much about gravity.
These navigation tools were used on Apollo because things we take for granted, like cheap calculators and small computers, weren't available or were too big to put in the spacecraft .rcgldr said:A bit of trivia, part of Apollo's navigation involved something like a sextant and star charts, to accurately locate position and orientation of the Apollo, which was needed to make accurate thrust based transitions in and out of orbit from the Earth and moon. Earth based systems could track the Apollo for the Earth to lunar transition, but the moon to Earth transition thrust occurred past the far side of the moon.

The mathematics that took us to the moon is a combination of various mathematical concepts and theories, including calculus, geometry, algebra, and trigonometry.
Mathematics played a crucial role in the success of the Apollo missions by allowing scientists and engineers to calculate trajectories, orbital mechanics, and other important factors necessary for a successful journey to the moon.
The Apollo missions utilized various mathematical equations, including Newton's laws of motion, Kepler's laws of planetary motion, and the law of universal gravitation. These equations were used to calculate the spacecraft's trajectory, velocity, and other important parameters.
Computers were used extensively during the Apollo missions to perform complex calculations and simulations, allowing for more accurate and efficient use of mathematical concepts. Without computers, it would have been nearly impossible to complete the calculations necessary for the missions.
While the specific calculations and equations used for the Apollo missions may not be applicable to other planets and celestial bodies, the underlying principles of mathematics remain the same. Scientists and engineers continue to use mathematical concepts to explore and understand the universe.
