I’ve been casually thinking about this for a while and I don’t know what the answer is. It seems like the continuum model of an exponentially growing culture has to be an oversimplification that discards (or integrates over) single cell physiology

Technically caloric. But I do think that the some of the intricacies of thermal energy transfer are beyond a 10th grade class

While no one should excuse the teacher/administration, the student was at least in a position to learn the important life skill of dealing with ignorant people in a position of power who are convinced they are right. Learning this would frankly be more valuable than 6 points on a test

Maybe an unpopular opinion but while (assuming the other 5 Q’s were anything like the one quoted) the teacher should have been reviewed and at least reprimanded for incompetence, initiating a legal battle over this issue is a completely absurd and inappropriate thing for the parents to do

I agree that the argument won’t convince the Trump administration (who are attacking or because they see science and scientists as part of the opposition or “enemy within”) but I also think emphasizing the wanton destructiveness of the attacks is something that helps mobilize the populace

I mean, I don’t know the ins and outs of police work and I’m not a lawyer, but this seems really not normal. For reference, this is in Pittsfield Township, Michigan

It seems likely that the officer was serving a warrant. Why would you need an unmarked cars for that? (Yes, rhetorical question)
September 30, 2025 at 9:45 PM
Did a quick search, and it appears police can use unmarked cars in Michigan under some circumstances. All those circumstances I found listed seemed to be irrelevant to whatever was going on here
