Multiplying that massive number by 4.22 gives you roughly the one that's in my post. <BR/><BR/>However, as for how I estimated the distance to proxima centuri to <I>to the nearest metre</I>... well, I didn't of course! Artistic liberty, all for effect ;)<BR/><BR/>Jeremyjeremyhttps://www.blogger.com/profile/17353716090668341520noreply@blogger.comtag:blogger.com,1999:blog-956701540737748712.post-33572411484356198822008-02-18T06:55:00.000+02:002008-02-18T06:55:00.000+02:00As somebody who loves math, and would actually cal...As somebody who loves math, and would actually calculate a number that big just for the fun of it, I'd like to know...<BR/><BR/>How do you get 4.22 out of 39 924 282 590 234 214 738 126 847? I could understand 3.99, but 4.22 is just well off.<BR/><BR/>I would have thought it would be 3.9 X 10^24.<BR/><BR/>Could you please explain?<BR/><BR/>I'm not trying to be flipant, I'm just explaining my confusion.<BR/><BR/>And I'm curious, for I do love math.<BR/><BR/>ThixiaAnonymousnoreply@blogger.com
