  • As a lefty who received “gifts” from her conservative parents, let me suggest giving the gift separate from a major holiday. Something I wish my parents had done that could work as a gift of sorts for you would be to take your son out for coffee or breakfast. Nothing fancy, preferably not busy. Talk to them about why they think what they do. Don’t combat them, just try to understand. Ask them if they would be comfortable talking more after you’ve had time to think about what they said.

    “Hey [child’s name], you know that we have strong beliefs about certain subjects. We feel we have good reasons to believe the things we do, but there are smart people in the world who disagree with us. You are a smart kid, and that is reflected in the way you look for answers to problems that the way you have been brought up to think hasn’t offered a solution for. It would mean the world to your mom and I to know out son better, what are some things you’ve thought deeply about recently?”



  • The best low hassle printing is going to be resin. You can get a decent Elegoo or Anycubic model for only a few hundred dollars. The only real hassle is cutting supports, washing your prints, and curing the resin. In my experience, water washable resin is the way to go.

    Of course, depending on what you are printing, you may not have as much use for a resin printer.

    Obligatory ventilate your work area and use your ppe.

    Edit: not sure why downvotes. Is this sub anti-resin?






  • “The rule in question, known as Bredt’s rule in textbooks, was reported in 1924. It states that molecules cannot have a carbon-carbon double bond at the ring junction of a bridged bicyclic molecule, also known as the “bridgehead” position. The double bond on these structures would have distorted, twisted geometrical shapes that deviate from the rigid geometry of alkenes taught in textbooks.
    …A paper published by UCLA scientists in the journal Science has invalidated that idea. They show how to make several kinds of molecules that violate Bredt’s rule, called anti-Bredt olefins, or ABOs, allowing chemists to find practical ways to make and use them in reactions.”



  • 30mph (48kmh) is the minimum, cars will also be going faster than that. Also, people need to cross the street, not just walk alongside it. Regardless, whether drivers or pedestrians are the issue, accidents happen. They are more likely to happen, and more likely to be fatal as vehicle speed increases.

    From the Institute for Road Safety Research, page 2:
    “According to an overview of recent studies (Rósen et al., 2011): at a collision speed of 20 km/h nearly all pedestrians survive a crash with a passenger car; about 90% survive at a collision speed of 40 km/h, at a collision speed of 80 km/h the number of survivors is less than 50%, and at a collision speed of 100 km/h only 10% of the pedestrians survive.”

    Areas with minimum speeds of 30mph in areas with pedestrians accept that at least 1 in 10 will die. This is easily reduced to negligible fatalities by having lower speed limits. Not doing so says we care more about saving some of the drivers’ time than the lives of pedestrians.
