This picture will be a core part of the conspiracy theories in five years.


The crazy part being the third-person perspective. From the perspective (stitching?), it looks like the camera isn't attached to the rover.


I'd really love to see how they pulled this off. I can't think of any way to do it without using a second camera at some point.


See elsewhere in the thread [1] where I discussed this.

"SUPPOSED TO BE DRY MARTIAN DUST? HOW COME IT STICKS TO DRY WHEELS THEN?" etc etc.


Why does the dry martian dust stick to the dry wheels? An electrostatic effect?


Replying to myself. I asked Emily Lakdawalla on Twitter. She's a journalist for The Planetary Society website, has great info on all the rover stuff.

Rodney Ramsey: @elakdawalla Maybe you can answer a curious Q for me... Why does Mars dust stick to Curiosity's wheels?

Emily Lakdawalla: @RodneyRamsey Electrostatic! The dust is extremely fine, Mars super dry.


sadly that is most likely the truth. I already saw some convo about people claiming some of the images were fake or doctored. Perhaps these people dont quite understand how mosaics work


You can actually see footsteps on the left.


I hope you're joking...


Yea, I wonder if they still have the 55 pictures they stitched this together from.


> the ACT (and by association the SAT)

As someone who nearly aced both, the ACT is a noticeably better test. The SAT has a lot of dumb and predictable tricks involved. The ACT requires more actual ability.


> Cheating degrades the quality of education at any level.

Not in the least! You can argue that it degrades the prestige or something like that, but the education remains the same.


I would argue it hurts after the cheating, though possibly not precisely when it occurs. Later courses, things that build on what was cheated, that kind of thing. Time (and money, and happiness) must be spent to deal with people who aren't prepared, degrading the quality of what the legitimate ones receive, and the educator's time.


I definitely sympathize with this. I used to be (and to some extent still am) the sort of person who would get in a lot of social trouble for being too blunt about things, or for focusing on results rather than social niceties. But I’ve come to realize that in order to really value merit and honesty, good communication skills are a prerequisite. I’m going to focus on the second issue, since I think the merit issue is clearer. (There’s a reason we value languages other than assembly, and people like Bill Nye.)

If you want to be honest, you must first learn communication skills. It is impossible to communicate honestly if you can’t communicate.

Languages do not inherently contain meaning. The only reason we are able to speak and understand each other in English is because there is a social consensus that certain words and phrases mean certain things. If you try to speak to someone who isn’t part of that social consensus (because they speak only a different language, say), your words are meaningless.

Therefore, if you say some words to people, and every time they invariably interpret your words as meaning, “This person is socially aggressive and is disagreeing with me as a power play”, then that is what those words mean. It is almost entirely irrelevant that you intended them to mean, “It is my objective analysis that your plan is bad.”

Since you probably don’t believe, “I want to make a power play on this person”, you are accidentally being dishonest by stating your opinion the way you did. If you want to communicate, “I think your plan is a bad one, and that we ought to try something different”, then you must put in the effort to actually learn how to communicate that.

To take a concrete example, say a friend were to invite you to a movie. The movie is quite bad, and you have a variety of criticisms of it. At the end of the night, your friend asks, “So what did you think?” If you wish to communicate, “I thought it was a bad movie”, you cannot scowl and say, “Typical hollywood tripe.” That would accidentally be dishonest, because you would be communicating, “I’m in a bad mood, and quite possibly angry at you. Also, I’m completely uninterested in your opinion.” Instead, you might try something like smiling and saying, “Oh, it was exactly as terrible as I was expecting. I’m already composing my facebook take-down in my head. What did you think?” This more honestly communicates, “I found the movie lacking, but I’m in a good mood and glad we spent time together.” (Alternatively, if you do happen to be in a bad mood, it’s probably not because of the movie. So you might look thoughtful and say, “Well, I thought it was pretty mediocre, but I’ve been in a bad mood recently anyway, because of X, so I might just be being unfair.”)
