im trying to figure out the probability of a 9 y/o kid going right through an object. im trying to do this with a compacted form of schrodingers equation: e^(-2*(m*v/H/2pi)*l) where l = 22,34mm, h = plancks constant, m = 30 kg and v = 1,64 m/s but everywhere i look it keeps saying it is 0,999... but it should be something REALLY tiny. could you help me? thx!

  • $\begingroup$ Units of l are milimeters $\endgroup$ – Zeb Jonkman Apr 5 at 15:51

  • $\begingroup$ So... is walking through walls is, technically, not impossible? $\endgroup$ – whatever Apr 5 at 16:11
  • $\begingroup$ Yes, but more probable would be to have a vital organ go through; leaving the rest of you behind. $\endgroup$ – Paul Childs Apr 5 at 21:40

Could you potentially have forgotten the exponent for planks constant? Or maybe got the sign wrong on it. I get near zero. Computationally it is so small it doesn't fit within the double precision limits of my computer calculator; registering an underflow error. Potentially you might be getting some computational undefined behaviour.
