  • Republicans across the country are pushing bills to stop government 'weather modification'

    Jump

  • Do new oil and gas leases qualify as weather modification? What about clear cutting forests and draining wetlands?

  • Tomato season is here

    Jump

  • Does your household use that much tomato goods through the year? Do you sell/ give away a good portion of that?

  • 🤯 Life Hack Alert

    Jump

  • Yeah that's my attitude as well. I grow the things that are significantly better straight out of the garden. The best tomatoes are too fragile to go through the sorting machinery, so growing your own enables much higher quality produce. Berries are way better picked ripe. Green beans are also super easy to grow and are better fresh.

    Then there's varieties that just aren't popular enough for many stores to stock and specialty stores are far and expensive: patty pan squash, molokhia, ground cherries, shallots, celery leaves (I don't like the stalk), a variety of herbs, peppers that aren't bell or jalapeno, etc.

  • [Article] Marathon Fusion says it can produce gold as fusion reactor byproduct

    Jump

  • This article is based on a preprint paper that hasn't been peer reviewed yet.

    Mercury vapor would be really bad to have in a fusion plasma. It would drastically increase energy loss and would make maintaining the plasma difficult.

  • What's the Holy Grail item in your hobby?

    Jump

  • American chestnuts will die here, but I have a magnificent large Chinese chestnut tree in my yard. It's not the same, but at least we get to harvest some 10-15 gallons of chestnuts every fall.

  • How effective are life jackets in rapidly flowing deep flood waters?

    Jump

  • And you hitting submerged objects that aren't flowing. I remember cutting my hand on a rock while going through rapids with a life jacket on. You need to practice keeping your feet downstream when in whitewater conditions.

  • Why do some companies like a utility put out ads?

    Jump

  • Is your electric company requesting a rate increase from a public utilities commission?

  • Hypothetical. Would this be permitted in a US state: long hours, little work, and sub-minimum wage. (please click for details).

    Jump

  • Salary also can't be exempt from overtime if the salary works out to less than minimum wage for the hours worked. So only 2080 of the 6000 hours could be minimum wage and the other 3920 would be paid at time and a half.

  • Hotels have developed a new revenue stream: "algorithmic" smoke detectors

    Jump

  • Isn't this a textbook candidate for a class action suit?

  • Why does stuff move in a parabola on earth but in an ellipse in space?

    Jump

  • Are you familiar with the difference between polar (r, theta) coordinates and cartesian (x,y) coordinates? Parabolas are the solution to gravity that is uniform no matter where you sample. It assumes that gravity points in the same direction with the same magnitude no matter where you are. In this model, gravitational acceleration is always 9.81 m/s^2 in the -y direction. That is a reasonable simplification for things that are at the human scale constrained to near the earth's surface. Deviations from air resistance will matter far more than errors stemming from that assumption anyway.

    Conic sections are the solutions to gravity that is between two objects where the force is along the line between the center of mass of both objects and the strength is inversely proportional to the square of separation. Now you need polar cpordinates and the direction of gravity changes as things move around. This works pretty well for orbits around the earth and orbits around the sun, because the earth is so much more massive than sattelites that orbit it, and the sun is so much more massive than things that orbit it. If you need really precise orbit trajectories, ellipses aren't truly accurate either. You need to account for all the orbiting bodies in the system. The 3-body problem famously doesn't have purely analytical solutions, and you need to resort to numerical methods to calculate trajectories.

    So both solutions come from simplified mathematical models. Despite being simplifications, their predictive power is actually very goood. However, like you are intuiting, it's important to know when those simplifying assumptions lead to errors that start to become important. It's hard to come up with a particular threshold for when you need to switch from one model to another, because it really depends on how much accuracy your application needs.

  • Can I lick it?

    Jump

  • Radon should be yellow. You don't want long term exposure of it in your lungs, but it's still mostly chemically inert and not a significant immediate danger.

  • Let Us Pray

    Jump

  • I know they don't like to read long bills, but maybe one of their interns can read Matthew 6:1-8 to them.

    What app/program do you wish existed and what does it do that you've not found elsewhere?

    Jump

  • I did search for "weather on the way" in google play store. While they don't have an android app, I found two similar apps that do a lot of what I wanted: "drive weather" and "highway weather." Thank you for the search term that yielded results. I like that the"highway weather" app allows adding in rest stops and propagates the change into the forecast.

    I will note that neither of these options seem to offer turn by turn navigation. So there is still room for some of the navigation apps to integrate this functionality.

    Jump

  • I have long wanted a weather forecast along route in navigation apps for long trips. Ideally you could add in stops and estimate how long you would need to wait for storms to pass over.

    What is some restful/profoundly relaxing video game music?

    Jump

  • Is there any hope trying to fixing this cooler?

    Jump

  • This an assembly specifically designed to spread out heat, applying heat to the pipes will just make the whole thing hot. If you did take a giant blowtorch to it and got it hot enough to soften the pipes, you'd probably dry out the pipes (potentially explosively).

    Heat pipes are cold worked in the factory. The metals chosen are ductile. Adding lots of heat will only add to the problems.

  • YSK that apart from not having a car and voting, the single greatest thing you can do for the climate is simply eating less red meat.

    Jump

  • Sure, but it's normalized to kgs of product. With two lattes a day, 2kg of coffee lasts me more than 2 months. 2kgs per person of beef would last many households less than a week.

    If you were to normalize to average daily consumption, coffee and chocolate would be significantly lower ranked. It's ok to keep some indulgences while focusing on higher impact reductions.

  • How can I start getting familiar with the plants, trees and animals around where I live?

    Jump

  • It is available on android as well.

  • Do you ever get phantom vibrations on your phone?

    Jump

  • The ridges of the weave in my pants sometimes produces a vibration that is similar frequency and intensity as my phone vibrate. It totally triggers the check the phone reflex even if it happens while my phone is in my hand.
