  • Marble has a density of 0.098 lbs/in3. So a 500lb sphere has a volume of 500lb/.098lb/in3= 5102 in3. That gives a radius of (5102 in3 * (3/(4pi)))(1/3)= 10.68 in.

    Let’s say the bowl it sits in has 2/3 the radius. So 7.12in. That makes the enclosed surface area pi*( 7.12in) 2= 160in2. So 500lbs/160in2 = 3.14 psi. How fast do you think the water will spray out at 3.14 psi? Without any drag, out of an ideal nozzle, it would be 6.5mph. However, the pressure will actually be higher in the middle and tapers off to 0 at the edge thanks to the flow diverging and drag. So really the pressure drop at the opening is even smaller.

    There’s a lot of lifting area which means you don’t actually need much pressure. You can lift entire buildings with large water bags.





  • I don’t agree that it’s better than every dessert. Learn to bake your own desserts and they don’t have to be too sweet, but can still have amazing flavors and textures.

    However, I do like fresh fruits better than any sweetened electrolyte drinks. Melons and cucumbers combined with a salty snack is very refreshing and won’t spike your blood sugar nearly so much as a sports drink.

    It’s not the disc itself that people care about, it’s having a transferrable license. People want the option to rent games, or give them away/resell after playing. Physical media provides some legal protections for that because you are buying a license attached to the thing storing the software.

    Digital distribution is a perfectly fine way to get a game, if it weren’t synonymous with big companies taking away your ownership of the right to use software you purchased. You can’t share a game you enjoyed with friends. If you lose access to your account you’re SOL. If the host server shutsdown, you better have had a stable copy installed/backed up.

    People don’t hate digital downloads, they hate the consumer abuse they have enabled. Stop the consumer abuse, and only collectors will care about physical media.


  • 2 * 0 = 0

    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.





  • Currently, large corporate landlords are willing to let housing units sit empty vs letting market rates drop. A company with 500 units makes the same amount leasing 400 units at $1500/mo as they would leasing 470 units at $1300/mo and they have less overhead. The realpage software lets them coordinate with all the other corporate landlords without direct communication.

    The reason I think this policy would help renters is by making vacant units significantly more expensive and pushing corporate property managers to actually compete rather than sit on vacancies.


  • I think I’d rather see this adressed on the property tax side with a homestead tax exemption. Let counties and municipalities significantly raise property tax rates then offer homestead tax rebates to the primary resident. Maybe even offer a monthly rebate to match rent/mortgage payments. Rent would go up, but the rebate should match the rent increase.

    This would make empty units, short term rentals, and vacation home more expensive to hold on to compared to being pccupied by a long term resident. This would also let each region decide on the ratio of occupied vs unoccupied net property tax rates to dial in what works for them. A coastal community might have a much different equilibrium point than a suburb to a big city for example.

    A lot of areas already have homestead exemptions for seniors and low income residents, so it doesn’t even require much in terms of new legal frameworks.



  • 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.
