    UV filter for home central heating?

    Thanks. I think there's a lot of things we can do to keep up our air more effectively (and cheaper) than a UV filter in our airways.

    Beware Fake History

    Ironic. I'd always assumed the era of historical ambiguity would come to an end once we started keeping indelible records of events. But the tables have flipped. Now, instead of ambiguity because of too few records, we have ambiguity because of too many records (many of which are fake).

    Beware Fake History

    Thanks, yeah. I have suspected this for quite some time. Good to have it objectively confirmed. Whenever I see one of these pseudo-historical stories, I check Wiki to see if the events have any basis in fact, and then ignore the narrative, which obviously must have been retconned. What keeps me...

    UV filter for home central heating?

    Yes, this is as I understand it: two types - one for air flow, one for filter sterilization.

    UV filter for home central heating?

    Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now...

    New person here, where do I post my own personal hypothesis?

    This whole thread is kicking down. A young, enthusiastic science buff should be guided toward learning, not pantsed and wedgied.

    New person here, where do I post my own personal hypothesis?

    welcome @Legodudelol9a. There are plenty of sites on the innertoobs that will entertain personal hypotheses. This is not one of them. But feel free to come in, look around, kick the tires.

    What type of energy is actually stored inside an atom?

    Energy is not a thing in itself; it is a property of a system, and it can change forms. A fast-moving atom has kinetic energy, which, if directed upward can be converted into potential energy, or if toward the ground, can be converted to heat energy, etc. When an atom is split, the components...
