Hi. Here's a question: if you were in London, England, and you placed an object representing the Sun on the floor, and then placed another object, representing Earth, ten paces from the Sun, on that scale, where is the nearest star?

I can copy Maple text as MathML but I can't seem to be able to convert it to Tex...

Anyway, a pace can be a unit of length of 0.75 meters. Alpha Centauri is 4.37 light years away from our star system.

I have better things to do than care about learning shit programing in Tex, and this site may just have shit, outdated and unfriendly software.

The nearest star would 10 paces.

Alpha Centuri would be approximately 2,700 km away. That is assuming 10 paces = 3o m. That is also assuming I didn't make an arithmetic error!

Just one university using Maple (others could use MATLAB, Mathematica, or whatever) is more than enough to say this forum sucks for lack of point and click capability.

Why can I not just easily use MathML and why would Maple only allow to copy expressions in MathML?

The answer is on that scale, the nearest star (excluding the sun) would be in Johannesberg.

I noticed. Now you know the answer, what do you think?

Quick "back of the envelope" estimate. 4.37 ly, using the Julian uear of 365.25 day equals 2,298,445 light min. The Earth is roughly 8 light min from the Sun, so at at 10 paces, that is 1.25 paces per light min, which puts Alpha C at a distance of 2,873,056 paces. If you did your recommended 10,000 steps per day, it would take you 287 days or 79% of a year to cover that distance.

I think it's an incredibly great distance. From that distance, the Earth is flat.

I saw the question on, "Porridge," an English sit-com set in prison.

Yes Ronnee Barkay.

Actually I wrote, "excluding the Sun" earlier in thread. The post where I revealed the answer.
