    In the relativistic case, the entire mass of the car would be instantly converted to energy at the rate of mc^2, which for a 1.5 tonne car would be an explosion equivalent to several gigatons of TNT. That would be one incentive to drive safely.

    Not four times as bad? Or some other even higher number? I’d have thought driving/crashing at 100km/h was much more dangerous than driving/crashing at 50km/h.

    In terms of released energy, yes, it’s four times as bad thanks to the “squared” in the theory of relativity.

    *cough* Not quite - it's all Newtonian. A car's kinetic energy is 1/2(mv^2). So one car hitting a perfectly strong wall at 100km/h will release four times the energy of the same car hitting the same wall at 50 km/h; but two identical cars hitting each other head on at identical speeds will only release twice as much as one hitting a wall at the same speed.

    Think of it this way - in both the car-hits-wall case and the car-hits-car case, each car decelerates from v to zero during the collision, so the total energy is e * (number of cars).

    (Russell - how about LaTeX parsing for comments?)

    Fruit in curries was quite clearly a thing.

    My one really dud experience at Satya was when once several years ago I ordered the "Navratan Koorma", described in the menu as "Fruits nuts and veges cooked in koorma", and was served what seemed to be their standard vegetable korma with half a tin of Watties fruit salad emptied over the top, complete with a few pale bits of cherry. Since then I've tried almost everything else on the menu and loved it all.

    I've never quite had the nerve to order Navratan Koorma again and discover whether the one I had was some kind of aberration. Or perhaps tinned fruit salad is a common ingredient in southern India, and I'm just being precious.

    Also, everyone's talking about sausage curries with sultana and apple etc., but am I the only one here whose standard childhood curry was mince curry with fruit?

    Are things different in other cities? Are there regional Indian restaurants?

    Satya is South Indian, but as you say they have a few of the northern/Anglo Indian fall-backs just in case. There are a few good Sri Lankan places around: 7 Siri in Sandringham has excellent food (try the Lump Rice) but the service is indifferent; and there used to be a really good one in a dodgy foodcourt in East Tamaki, I forget the name.

    I seem to recall sultanas being de rigueur in my granddad’s sausage curry.

    "Sultanas the size of boiled eggs" as I believe Terry Pratchett termed it.

    butter chicken [...] has a safe English name involving two ordinary Pakeha ingredients

    There's an amusing family anecdote about my grandparents being broadsided by "Butter Chicken" pies from their local dairy. Amusing to us; they were livid.

    Look how hard Stephen Morris is working in that last one. No wonder he was so early on the drum machine bandwagon. And Curtis trying to get his dance on, but the audience is giving him nothing. Not that it would have helped.

  • Hard News: Friday Music: The First Time,

    I'm young enough that the details of the first couple of international bands I heard are available online as an aid to memory, no doubt due to the efforts of a few geeky fans: Supergrass at Wellington Town Hall and The Gurgs at the VUW Student Union, both in 2000. I would have been 17.

    I'm pretty sure I had been to local gigs earlier (I'm not counting Smokefree Rockquest), but I can't remember what. I heard the Clean reunion at the old Bodega whenever that was, and that wasn't the first gig I went to there (anyone know when it was pulled down?).

    Of course the first proper concert I went to was the Orpheus Choir singing the Bach Mass in B Minor when I was 9 or 10.

    no boycott of any advertiser was undertaken or, so far as I’m aware, even proposed

    It's like the Man Ban: if you can convince enough people to call it a duck loudly enough and frequently enough then it is a duck.
