    A physics paper with an official publication date of Jan 2025, "On the same origin of quantum physics and general relativity from Riemannian geometry and Planck scale formalism", already has an expression of concern. If a paper is retracted before it is published, does the journal vanish in a catastrophic spacetime paradox?

    Turns out infrared thermometers don't get the temperature of water right.
    Alerted to this when dying a shirt.
    IR thermometer said 85°C - while I wondered why the water was gently bubbling.
    Digging out a mercury thermometer revealed why - it was at simmering at 100°C.

    The shirt still seems to have dyed okay.

    Any physicist care to explain?
