    "abstract": "The Heisenberg uncertainty principle for material objects is an essential\ncorner stone of quantum mechanics and clearly visualizes the wave nature of\nmatter. Here we report a demonstration of the Heisenberg uncertainty principle\nfor the most massive, complex and hottest single object so far, the fullerene\nmolecule C70 at a temperature of 900 K. We find a good quantitative agreement\nwith the theoretical expectation: dx * dp = h, where dx is the width of the\nrestricting slit, dp is the momentum transfer required to deflect the fullerene\nto the first interference minimum and h is Planck\u0027s quantum of action.",
