comment Unitarity of PMNS matrix
if any row or column squared sums to something less than one (experimentally), this is an indication that we're missing something, e.g. a fourth row/column corresponding to an additional species of neutrinos.

comment Software for calculating Feynman Diagrams
MadGraph does only tree level (no loops but many outgoing particles), MadGraph5_aMC@NLO can do one loop

comment Kitchen floor dries faster with lights on?
although traditional incandescent light bulbs and fluorescent tube lights have an efficiency far below 50% (according to en.wikipedia.org/wiki/Fluorescent_lamp#Luminous_efficacy), so more energy is converted to heat than to light for these.

yes, good point, and the water in turn would heat the region of air immediately above the water

comment How detectors in particle colliders can differentiate neutrons from antineutrons?
because anti-quarks in the anti-neutrons annihilate with the quarks in the protons and neutrons in the carbon nuclei while at such low energies, a neutron essentially behaves like an (unbreakable) ball

comment How can I measure the speed of a figure skater's spin?
the stroboscope (or camera flash which has such a function) probably only works well if she can spin for a enough time while you adjust the stroboscope's frequency...

comment Why more than one Higgs?
Is there a typo here we don't want the theory to be renormalisable ?
