  • 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”






  • 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.








  • I used to be that way too, but it’s a skill that you learn through practice. Like push yourself to get into things just a teeny tiny bit to start with for now. Then after awhile it’ll be easy to get to that point of toe-dipping, so then you push yourself to go in a bit more next time, and do that every time you’re at some activity, and then eventually you’ll find it easy to jump right into the deep end of every activity. But it does take some effort to push yourself in the earlier stages

    I assume you’re quite young, which is great! I’d suggest learning to enthusiastically jump into whatever activity you wind up in. It’s way more fun that way.

    At a comic con? Throw on a mask and start talking in a funny voice!

    At an opera? Listen closely to the sounds and try to enjoy the artisticness of the performance!

    In a big grassy field with nothing to do? Take your shoes off and let the grass tickle your feet!

    In my experience it’s easy to judge things as lame and to tell yourself that you’re too cool for that thing, but that winds up not being fun, and you wind up missing out on a lot of stuff that you actually would’ve enjoyed if you let yourself get into it. Learn to be open to trying new types of experiences and you’ll wind up having more fun in life!
