  • If you don’t want to accept a present for your child because you think it’s bad then you say that. When a person offers a gift to your child and your immediate response is that you plan on selling it that makes you a dick

    Also how is this family both so poor that they need to sell the shoes for groceries but also so selective where they don’t want a practically new pair of popular mainstream shoes






  • To be fair neutrons are usually harder to block. Lead has a tenth thickness of 2” for gammas whereas the smallest tenth thickness for neutrons is around 6” for borated poly and the most common shields are water at 10” and concrete at 14”

    So yeah it is different but overall it takes much thicker shields to block neutrons than gammas








  • Imagine you owned a store, what seems better, having 40 customers come in and all of them buy or having 80 people come in and all use up time with a salesman and then only 45 people purchase. You would end up spending a much more significant amount of the sales revenue on the larger showroom and more staff. This isn’t my opinion this is why the American market has been prioritized, that and the fact that Americans spend more on cars per year

    California has different emissions requirements (not safety) but since they are a strict upgrade to the rest of the US (and comparable to other int markets) as long as you follow their requirements all cars in the US can be sold without any contradictory requirements

    A very common kpi used is to examine the success of a campaign in a per target demographic so having the much lower response rate is worse


  • If you are making an ad campaign, all of the US speaks the same language, generally has the same safety regulations, and a much larger percent of the people are your target ad personnel

    The EU is a cohesive unit for regulations but speak many different language and once you branch out of the EU to all of Europe you can see why there are huge advantages to advertising in the US.

    So no it’s not the absolute number that matters

    Supercritical CO2 has been looked at a lot for the Brayton cycle which can get 50% efficiency compared to steam that generally caps out around 34%

    The US and china both published studies talking about a brayton turbine but to my knowledge no commercial plants running off of it have been built yet
