I thought it was the ability to repeat whatever you did.

Tell Me How My Blog Tastes: I thought it was the ability to repeat whatever you did.


It does help to meticulously document those steps, like by writing it down, you know so someone could duplicate your results.

Yes, but some people write down what they did & claim to have witnessed a scientific breakthrough. Then no one else can repeat what they claim happened. It's a mystery, I tells ya.

OK. Thanks subby for Scott Manley

This is nice, and congrats to everyone who has been excited about DART. Mr. Manley kindly explains that there is some unresolved science. That is nice. And cheers for mentioning the ATLAS project.

Ignore my curmudgeonly grumbling that this was  a pretty big effort that could have been better spent observing, tracking, and categorizing asteroids. Manley rightly notes that this is a ball of ice and rubble and points to some jetting of vaporized ice, but aren't we back to square one now, wondering if we will get good results from some more-solid mass with little ice?

And if we have so much ice on a lot of asteroids, then vaporizing the ice with a nuclear weapon would do more than some kinetic impact, right? I used to think nukes were useless against asteroids, but if there is THAT MUCH ICE, then nukes are back on the menu, right? If nothing else, they give a lot of bang for the buck.

Which raises my point again: maybe we should study the asteroids more to categorize and characterize them according to their constituents before we go to all the trouble to whack them from a distance.

I am not critical so much as impatient.
