I can't agree with this more strongly.
Technology can be a useful addition to a lecture, but it doesn't ALWAYS add value.
The most engaging, informative CS courses I ever took involved nothing more than the instructor using a blackboard. Some of the worst on the other hand, came as a result of poorly applied tech.
'conditional commitment' to provide a partial guarantee for a rumored $98.5 million loan
News, huh?
Hello,
Suppose you were falling into a black hole, and you didn't get turned into spaghetti (as might be possible if you're approaching the event horizon of a supermassive black hole). Would the event horizon seem to retreat before you? I mean, light can't escape a black hole's event horizon as we see it, but if you're falling in, wouldn't you be able to see further into the black hole as you fall?

Well, since sight depends on light reflecting off of objects to work... No, as you approached the event horizon, you still wouldn't be able to see into the black hole, as no light would be escaping (hence no visual information conveyed).
As to other point, no, the event horizon would not appear to be receding. You would seem to be approaching it normally (from your perspective), however due to time dilation, the rest of the universe would seem to be aging quite rapidly compared to you.
Unfortunately, high school is the highest education the majority receive.
Sorry, but that doesn't mean that high school is the appropriate venue for that sort of discussion. In a high school science course, the aim of the curriculum is to provide a foundational education. Unfortunately, this does not include advanced evolutionary theory.
Right, but I don't hear anyone complaining when teachers say that we don't have a complete understanding of it either. Unfortunately, if a teacher were to say that there are things we don't understand about evolution, everyone gets in a tizzy and accuses the teacher of proselytizing impressionable young minds.
If this was all that teachers were required to say, then I'm perfectly comfortable with this. I am not comfortable, however, with the undue focus on evolution theory as flawed. It inaccurately characterizes evolution as a theory that is fundamentally contested, when in reality it is supported by a wealth of evidence from a variety of fields.
Ideas should NEVER be off the discussion table when it comes to science. Nor should any theory or even law be above challenge.
No one is say that evolution shouldn't be held up to the full rigor of scientific scrutiny. But there's a huge difference between criticizing hypothesized evolutionary mechanisms and criticizing the underlying theory.
In the scientific community, the fundamental principles of evolution have held up for a LONG time. This is what should be taught to school children. The extreme emphasis by certain groups on the "weaknesses" of evolutionary theory are meant to sow doubt in an otherwise uneducated audience (which kids are).
Should kids know that the specific details of evolution haven't been 100% sorted out yet? Yes. Should we go out of our way to spend time discussing these open questions? Sure. In an advanced setting. Not grade school. Not high school.
Frankly, we don't have a perfect understanding of how gravity works either. Yet somehow, I can't hear anyone screaming that our children must be educated on the "weaknesses" of that particular subject. I wonder why?
If you have a procedure with 10 parameters, you probably missed some.
