@cmuratori Well, I can look at that and think "hmm, what shape is it falling in? I guess it's a loop of four half-parabolas"

@hamishtodd1 What? Only if you already knew the math to begin with! Nobody learned the double-integral of constant acceleration from Portal.2 replies 0 retweets 0 likes -

@cmuratori Well I don't know the double-integral of constant acceleration! I have a maths degree, but I don't think that's required...1 reply 0 retweets 0 likes -

@hamishtodd1 Yes you do - if the acceleration is g, velocity is tg and position is t^2g. You learn it in grade school physics.1 reply 0 retweets 0 likes -

@cmuratori@hamishtodd1 That's where the parabola comes from. It's why (Newtonian) gravitational arcs are parabolas not, say, cubics.6 replies 0 retweets 0 likes -

@cmuratori ...it's parabolas. I'm saying it lets you think about trajectories in this novel connected way.2 replies 0 retweets 0 likes -

@hamishtodd1 Right, that has nothing to do with the real world whatsoever. Which is what I'm trying to get across. Do you see that?7 replies 0 retweets 0 likes -

@cmuratori@hamishtodd1 The novelness is the result of _fictitious addition to physics_ that does not work in the real world.1 reply 0 retweets 0 likes -

@cmuratori@hamishtodd1 It is not a simplification, it is a highly erroneous addition, and those are not the same thing at all.1 reply 0 retweets 0 likes -

@cmuratori@hamishtodd1 Again, I still think Portal is a good game. But I think it's crazy to say that it helps teach physics...3 replies 1 retweet 0 likes
@cmuratori @hamishtodd1 ... any more so than does any other game with a Newtonian physics engine in it.
