AI Thread Summary
In space exploration, international standards favor metric units, with the meter being the primary measurement used by agencies like ESA and NASA. While the United States commonly uses customary units, metric measurements are prevalent in scientific and medical contexts. Russian and Chinese space agencies also utilize metric units for consistency in international collaboration. The discussion highlights the importance of metric units for global cooperation in space missions. Overall, metric units are the standard for sending objects into space.

Dear everyone,
I would like to know which one of the meter or the mile is used to send objects in the space please?
Indeed, the ESA is using the meter I suppose and the NASA the mile. What is used by the russian and the chinese agencies?
Thank you,

Emilie

International endovers would use metric units.
 
Thank you. The United-States' customary unit is the lbf.s, but the metric units are used in the medical and spatial industry.
 

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation has no solutions with positive integers if It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'Imaginary Pythagorus'

Thread 'Imaginary Pythagorus'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...
