  • of course, but this problem is solvable without any understanding of complex numbers, and 10*i^2 is a really clunky, multi-operation expression whereas -10 is just an integer.

    simplifying one’s answers is standard practice and any grader who received the answer in the OP would be obligated to point out that while technically correct, they’re missing the basic fact that the answer is -10.

    The Rube Goldberg comment is apt as the solution is absurdly complicated and overengineered for the task it performs.






  • then we agree that it’s incorrect to definitively say that a “palm tree” is not a tree.

    rigidly defending the boundaries of a biological category that’s not a monophylitic group is an exercise in futility. or maybe in linguistics, because if it’s not monophyletic it’s not “real” in an evolutionary sense and the question is in the cultural realm and somewhat subjective. It’s like the discussions about whether a certain food is a fruit/vegetable/etc.












  • They’ve made the first reusable orbital rockets (falcon 9 first stage), and made the practice routine.

    They’re the first to ever fly a full-flow-staged-combustion rocket engine (raptor), combining high power and high efficiency.

    Starship has already broken records (owing to its sheer size), and if it fully pans out it will be the largest rocket ever, and the first fully reusable orbital rocket. Next test flight is probably early next year.
