  • A single dna molecule is too small to see with the naked eye, but a few million dna molecules released from a few million microbes is easy to see IRL. In my bio lab days we did an experiment to isolate the dna molecules from a scoop of microbes, and at the end you wind up with a clump of dna molecules that together are about the size of an eraser head.

    And yeah as the other person said, the term “staining” is the official term used for what you’re calling “tagging”



  • I think this graph doesn’t have to move left to right, it can also move right to left. On several occasions quantum computing started to move up the “tech trigger” slope, but without any functional applications for the current technology the point slid back down to the left again.

    I think the graph needs at least one more demarcated region. After “tech trigger” there needs to be “real world applications”. Without real world applications you can never progress past the tech trigger phase.

    In chemistry this is the equivalent of Energy of Activation. If a reaction can’t get over the big first step, then it can’t proceed on to any secondary steps











  • You just said that AC can’t make an indoor space cooler than the temperature outside. This is completely wrong and easily disprovable by simply asking anyone who lives in a hot region. The air conditioned indoors is always MUCH cooler than temperature outside.

    Like, how do you think freezers work? The temperature inside the freezer stays below freezing while the ambient room temperature is 80 F.

    AC is an ACTIVE heat pump. It can push heat out to where it’s already hotter, because it’s using energy to do it. What you’re describing is a passive cooling system, but air conditioners are active systems that use energy to push heat against the gradient. It’s like how a passive water pipe can only have water flow down from it’s highest point, but a powered water pump can actively move water upward to a point above where it started.





  • If this is true, why would they release the information about how they did it?

    Yes there is some psychological warfare effect that will make hamas people feel scared for a short amount of time, but it will also make them change their security procedures to help prevent this method from working in the future. Their forensics were going to determine that it was a bomb, but they wouldn’t have been able to tell that the bomb was planted so far ahead of time.

    I’m not convinced this story is true. I’m not saying it’s false, but i am saying they had no incentive to tell the truth, and in fact they have incentive to lie so that hamas puts work into securing against the wrong method.
