    Everyone here is talking about how not having eyelids is messed up while I think being able to rotate your eyes either completely upward or completely forward is crazy!

    (Also having no eyelids to protect against the aggressive blinding lights of your predators/prey probably beats having your eyes destroyed by said predators/preys toxin spewing tentacles any day if the week!)

    Unless you WANT your transistor to be this way and use it so you put an actual led inside the plastic as well to mess with (i.e. turn on and off) the transistor!

    Also I would argue that wind could also be considered ‘steam’ turning a turbine. It’s just vapour pressure ‘steam’ with a LOT of other pollutants which somehow increase the efficiency!

    Habe ich versucht. Da ging ihr Vater ran? Irgendein Herr von X‽ Hält sich wohl für was besseres wenn er noch nicht mal seinen Namen sondern nur das “von” nennt… Jedenfalls sagt er Twitter könne momentan nicht ans Telefon gehen und ich stimme nie wieder anrufen.

    Irgendwie unsympathisch dieser Typ!



  • Also persönlich hätte ich eher a_i Element von { Schwarzer Filzstift } für alle i < n oder so geschrieben da für mich a ohne Index leicht von a mit index zu unterscheiden ist (z.B. weil das eine die gesamte Reihe/Folge und das andere die einzelnen Terme bezeichnet)!

    Und so wie du es dann geschrieben hast wäre für mich der ursprüngliche Fehler aus dem Maimai immer noch vorhanden…




  • So do I understand correctly that a certain hox gene is activated in basically all cells which are in the “domain” of a certain vertebrae and they all activate some subset of homeobox genes which in combination with the original hox gene cause them to start turning into all the different parts associated with that vertebrae (so organs and other structures)?

    Would we then need an entirely new hox gene to produce even a single gill? (I know you basically just laid out most of a response to this question.) Because I would assume although the exact point at which the development of our arms and legs begins is part of the whole hox gene “superstructure”, but couldn’t we ‘basically just’ highjack this same system and duplicate this gene to produce at least a single gill in the region where the current hox gene for our neck is expressed?

    Long story short: what is the biggest reason why we can’t just hack into a later part of the sequence and continue on from there with what you said?

    Or would your proposed plan also just end up like this in the final product and you laid it out like this because it’s already the most viable route into this mess? 😅


  • And that’s the thing:

    Assuming it did, you couldn’t see it approach until it hit you because it’s moving at the speed of light! It could also have happened, but just super far away such that it will never reach us due to expansion between its origin point and us being faster than c!

    Also just because the universe is frickin old doesn’t mean it is statistically bound to have happened. There are plenty of ways of making it even more astronomically unlikely but still possible…





  • Hmm but couldn’t we then also go even further and assume an idealized muscle car with an effective transmission to its wheels of 1:1 running at its optimal torque vs speed point and thus with a given speed of its wheels rotation for a given time?

    Aka convert energy into miles (traveled) or something (with the choice of motor and wheel diameter and everything else standardized ofc.)?
