• Was the Martian movie pretty accurate to what space travel to Mars will be like? I mean only white people will go to Mars?

    Best answer: Racially, no idea how accurate that would be. Depends if a bunch of crazy white nationalists are running the US in the 2040s like they are today I guess. Scott probably didn't give the ethnic makeup of the cast that much thought more than likely, and being a Briton he's not going to be particularly... show more
    Best answer: Racially, no idea how accurate that would be. Depends if a bunch of crazy white nationalists are running the US in the 2040s like they are today I guess.

    Scott probably didn't give the ethnic makeup of the cast that much thought more than likely, and being a Briton he's not going to be particularly sensitive to the racial politics in the US, some of which seems deviously subtle to an outsider. Like any decent Director he probably picked the best actors at auditions rather than focus grouping them like less reputable Hollywood chaff would.
    Had every member of the crew been given an overtly different ethnicity, there'd still be a vocal crowd of whiners on both sides of the political spectrum going on about tokenism.

    From what I can recall of the film's cast in general (not seen it since it was in the cinema) the mission director was Black, the Ares pilot was Hispanic and the head of JPL was Asian-American. Seems pretty diverse to me.

    I am pleased that a woman being the mission commander didn't ruffle any feathers at least. It shows there has at least been some progress in the knuckle dragging members of the cinema audience.

    But then if demographics is all you took away from seeing the film, then I think you must have completely missed the actual theme of the story.

  • Was I born in the 1900s?

    Best answer: Son, 20th century ran from 1st January 1900 and ended on the 31st December 1999. And YES! You were born in the century before this one! 19th Century. You are way too old to be online!!!

  • How do we know space really exists?

    No one has ever been more farther than a few hundred miles other than the Apollo missions and everybody knows those were fake. Plus, the Bible doesn't say anything about space. Stars are just lights in the sky. People could say their anything.

  • Integration problem?

    Best answer: I=Sdx/[xsqr(x^4-1)] Let u=sqr(x^4-1), then u^2=x^4-1 =>2udu=4(x^3)dx =>udu=2(x^3)dx =>dx=udu/[2(u^2+1)^(3/4)] I=Sudu/[2(u^2+1)u]=> I=(1/2)Sdu/(u^2+1) Let u=tanA, then du=sec^2(A)dA => I=(1/2)Ssec^2(A)dA/sec^2(A) => I=(1/2)SdA => I=(1/2)A+C => I=(1/2)tan^-1(x^4-1)+C (Ans.)

    Best answer: I=Sdx/[xsqr(x^4-1)]
    Let u=sqr(x^4-1), then u^2=x^4-1
    =>2udu=4(x^3)dx
    =>udu=2(x^3)dx
    =>dx=udu/[2(u^2+1)^(3/4)]

    I=Sudu/[2(u^2+1)u]=>
    I=(1/2)Sdu/(u^2+1)
    Let u=tanA, then du=sec^2(A)dA
    =>
    I=(1/2)Ssec^2(A)dA/sec^2(A)
    =>
    I=(1/2)SdA
    =>
    I=(1/2)A+C
    =>
    I=(1/2)tan^-1(x^4-1)+C (Ans.)

    Look into the method you suggested :
    I=S(x^3)dx/[(x^4)sqr(x^4-1)]
    Let x=1/u, then dx=-du/u^2
    =>
    I=-Sdu/[(1/u)sqr((1/u^4)-1))]
    =>
    I=-Sudu/sqr(1-u^4)
    =>
    I= -(1/2)Sd(u^2)/sqr[1-(u^2)^2]
    Let y=u^2, then dy=d(u^2)
    =
    I=-(1/2)Sdy/sqr(1-y^2)
    Let y=sinA, then dy=cosAdA
    =>
    I=(-1/2)ScosAdA/cosA
    =>
    I=(-1/2)A+C
    =>
    I=(-1/2)sin^-1(y)+C
    =>
    I=(-1/2)sin^-1(u^2)+C
    =>
    I=(-1/2)sin^-1(1/x^2)+C
    it is workable too, but clumsy.
