    My worst review said that my paper was technically sound but my entire specialty was a “cottage industry” generating computational models with no real-world relevance and therefore the paper should be rejected. The editor offered the opportunity to rebut but what could I say to something like that?

    (The reviewer still lives, as far as I know.)

    On the plus side, this meant that I was rejected by PNAS but then published in BJ.





  • There’s already a genetic mutation that does that.

    Myostatin-related muscle hypertrophy is not known to cause any medical problems, and affected individuals are intellectually normal.

    And it makes you look like this:

    That’s a house-cat, and it looks like that without having to lift weights. Some people have this mutation too, and it’s particularly dramatic in children who would otherwise never be that muscular. (I’d post pictures but I’m not sure about the ethics of sharing photos of other people’s swole toddlers even when they’re already available online.)

    Species with internal fertilization tend to have females care for the young because the male is the one who can leave first. He can maximize his reproductive success by searching for other females while the female is left with the choice between putting a lot more time and energy into caring for the offspring or leaving them to die.

    Species with external fertilization usually have the opposite dynamic. The female lays unfertilized eggs and then leaves. The male is the one stuck caring for them because they would die otherwise. However, the males of some species have evolved to be too clever for this:

    Among the maternal mouthbrooding cichlids, it is quite common … for the male to fertilise the eggs only once they are in the female’s mouth.








  • So far “more data” has been the solution to most problems, but I don’t think we’re close to the limit of how much useful information can be learned from the data even if we’re close to the limit of how much data is available. Look at the AIs that can’t draw hands. There are already many pictures of hands from every angle in their training data. Maybe just having ten times as many pictures of hands would solve the problem, but I’m confident that if that was not possible then doing more with the existing pictures would also work.* Algorithm design just needs some time to catch up.

    *I know that the data that is running out is text data. This is just an analogy.


  • What occasions are you referring to? I know people claim that Israeli use of white phosphorous munitions is illegal, but the law is actually quite specific about what an incendiary weapon is. Incendiary effects caused by weapons that were not designed with the specific purpose of causing incendiary effects are not prohibited. (As far as I can tell, even the deliberate use of such weapons in order to cause incendiary effects is allowed.) This is extremely permissive, because no reasonable country would actually agree not to use a weapon that it considered effective. Something like the firebombing of Dresden is banned, but little else.

    Incendiary weapons do not include:

    (i) Munitions which may have incidental incendiary effects, such as illuminants, tracers, smoke or signalling systems;

    (ii) Munitions designed to combine penetration, blast or fragmentation effects with an additional incendiary effect, such as armour-piercing projectiles, fragmentation shells, explosive bombs and similar combined-effects munitions in which the incendiary effect is not specifically designed to cause burn injury to persons, but to be used against military objectives, such as armoured vehicles, aircraft and installations or facilities.
