    "In 1944, while at a railway station he started chatting with a stranger who turned out to be an engineer who worked on ENIAC." I thought this was precisely the kind of careless ta…

    That doesn't sound quite like the Balboa I was taught, where the contact is at the top of the chest (and along the arms and hands of course) and the partners are slightly offset to…

    I thought the catch was going to be people who cannot stand upright.

    As far as I recall, QCD gives you a nice simple formula - a path integral over quantum operators - for any quantity you want. Lattice QCD works out the answer with great big Monte-…

    Goodness me, that's a blast from my very distant past! The venerable MILC code is still available: https://web.physics.utah.edu/~detar/milc/milc_qcd.html

    And since you had asked for the difference and not the ratio, the candidate immediately failed, right?

    A London taxi driver explained to me back in the 1980's how he liked fares from clubs where boys wore make-up because anyone who has spent three hours crimping and back-combing and…

    Being at the front and facing the orchestra, a conductor can also balance the volume of the various sections. An orchestra is usually large enough that when you are sitting in one …

    There is. A field theory in Minkowski space can be formulated in Euclidean space (and vice versa) with a technique called Wick rotation.

    The author says "the least likely element of this scenario is that Kellogg's will bring back free gifts". I have at home a bunch of squashy balls, eagerly sought by my son, from Ke…

    There is; the equation on the CERN mug in the photo is an example. For example, the gluon Lagrangian (Section 1) may be more compactly written -1/2 Tr F_{\mu\nu} F^{\mu\nu} for a s…

    I am suprised that there was only one. I knew someone who kept ferrets (to catch rabbits for her hawk) and was told that, as social animals, being kept in isolation would send them…

    The famous jibe is along the lines of "An empty taxi drew up outside 10 Downing Street and Clement Attlee got out", attributed to Winston Churchill, but I think he denied it.

    "Sculpting in time" is also the title of Tarkovsky's book which I haven't read, but I now have a new impetus to do so. Interesting about colour - perhaps a "less is more" thing. Th…
