  • If her primary concern is drinking water, you can get an under sink RO filter for a couple hundred. They’re very easy to install yourself. I’ve even helped a friend install one connected to their fridge so that the fridge dispenser would taste better. We are on city water that tests well except for microplastics and it sometimes tastes a little bit like soil or musty. The RO systems come with a particulate filter, carbon stage, Reverse Osmosis membrane, and a remineralization stage. RO is the only way to effectively remove microplastics.

    Personally, I would consider having a particulate filter and maybe water softener for the whole house. Neither of those should be crazy expensive. The water softener is only if your city water tests hard or if you have mineral buildup on your shower heads or in your dishwasher. If you’ve done any plumbing work, a particulate filter is pretty easy and affordable to install yourself.

    Reverse osmosis for the whole house is simply unnecessary. Install one yourself at the location your family gets their drinking/cooking water.

    This unit from mcmaster carr is what I use. Please be aware that chlorine does damage the RO membrane, so it is important to replace the first two filter stages approximately every 6 months. The fourth stage is recommended to be replaced yearly and the RO stage is supposed to be good for 2 yrs.

    Express Water also has some decent under sink and counter top options.

    Removing chlorine for the whole home requires a large activated carbon filter. They’re pretty expensive and the media gets saturated and has to be replaced every so often to keep absorbing chlorine. I would only do this if your wife has extremely sensitive skin that is getting irritated from your tap water.

    Oh and Reverse Osmosis systems waste more water than they clean without expensive recirculating pumps and controllers. That’s acceptable for a couple gallons of drinking water a day, but would be very wasteful and expensive in a whole-house system.

    Doubling the mass of photons is no change.

    Repealing Bournoulli’s principle requires changing how kinetic collisions of molecules translates into bulk measurables like pressure and density. There’s no way to predict what that does without first specifying more about what changes are made.





  • Ground hornets pattern match too. I had a massive nest I had never noticed in an old stump. They hadn’t bothered me despite having walked by numerous times. Then one time I hit the nest with the riding mower. Man that sucked. I’m not outright allergic, but a dozen stings does make me feel sick. After that, anytime I got within 20ft of the nest with the mower they would come out in force.

    Then a few years later I had the same thing happen with a raised garden bed. They never bothered me and I didn’t even know they were there, until my weedwacker attacked the entrance of the nest. I had to steer clear of that section of the garden for a few weeks after.

    Ground hornets are horrible.

    Yeah, black holes in media where they are depicted as a giant space vacuum cleaner is a big pet peave of mine. Unless you get really close, nothing is remarkable about the orbital mechanics of a black hole. The equivalent mass star would have burned you up at a much further distance than the gravity starts to become noticeably wonky.

    It’s a shame that writers focus so much on the gravity and neglect accretion disks and astrophysical jets which do extend large distances and are visually stunning as well.
