  1. Re:Seriously, $250,000? on NASA Setting Up $250,000 Mars Lander Competition · · Score: 1

    You say read it and yet you said that a launch that only needs to reach 800 meters "requires a reasonably well controlled vehicle with a delta-V of about 4,5 km/s or so"? That speed would mean you'd hit the required altitude in a little under 0.2 seconds. There is no possible interpretation of the requirements that would result in that statement.

    the only reason you said that is that you DIDN'T READ THE REQUIREMENTS and you're fucking pathetic at lying to cover it up after the fact.

    You clearly didn't read the actual challenge.

    The Challenge would award prizes for successful demonstration of an end-to-end autonomous operation to sequentially accomplish the following tasks: picking up the sample, inserting the sample into a single stage rocket in a horizontal position, erecting the rocket, launching the rocket to an altitude not less than 800m, deploying a sample container with the cache internally sealed and landing the container at less than 6m/s terminal velocity.

    $50,000 will be awarded to the team with the lowest total system mass that completes all tasks.

    The goal is not to get someone to build a Mars lander for $250k. The goal is to get get amateurs to think about innovative ideas for how to solve some of the problems in the hope that some of those ideas will be useful when NASA designs a real lander.

    It is possible people are vandalizing the cars

    Sure, but... "new rules were put in place requiring officers to document that both antennas were in place at the beginning and end of each shift. To guard against officers removing the antennas during their shifts, Tingirides said he requires patrol supervisors to make unannounced checks on cars."

    "Since the new protocols went into place, only one antenna has been found missing,"

    As soon as it became likely that the vandalism be caught, the vandalism suddenly dropped to almost zero despite the fact that only the officers knew of the change.

    So no... it's not possible that the public is vandalizing the cars.

    No, you can't. Calculus can tell you exactly how far the ball will travel down to the last millimeter if you account for all of the variables.

  14. Re:how calculus? on Flies That Do Calculus With Their Wings · · Score: 2

    you catching a ball is way, way more calculus.

    It really isn't. Catching a thrown ball requires practice, during which you learn more or less how a ball moves after being thrown without any actual understanding of the math behind it.

    If you were doing calculus, you'd know exactly where the ball was going as soon as you saw it moving and you could simply put your hand in the right place and wait for the ball to arrive.

    In reality, you get yourself into what looks like it might be the path the ball is going to take, then you constantly correct your position as the ball gets closer. It's more like a series of guesses where you're constantly told whether you're getting closer or further away from the correct answer and that is not calculus.

  15. It sounds that way, but it's intentionally deceptive. The trick is that the income inequality that Greenspan is referring to is the inequality between skilled and unskilled workers, not the disparity between CEOs and everyone else.

    He's arguing that programmers should be paid more like McDonald's burger flippers, not that CEOs shouldn't make hundreds or thousands of times more than their lowest paid employees.

    Expanding the H1-B program would increase competition and drive down wages, but only in the middle class. In fact, the added profits from paying workers less would probably increase the bonuses that CEOs get and create even more income inequality.

    The main question is: Where does the water California is watering its crops come from, and what will California do if the source is exhausted?

    The water California is watering its crops with comes primarily from rivers. The rivers are watershed from rain which condensed out of water vapor in the atmosphere. Most of that water they use then evaporates and becomes water vapor in the atmosphere where it eventually condenses and falls as rain again and feeds the rivers.

    It's the water cycle that you should have learned about in elementary school.

    The only reason the rivers that are the source of the water would be exhausted is if it stops raining. If that happens, it won't be because we were raising too much alfalfa.

    That's not his point either. His point is that he thinks we should stop researching walking robots because they wouldn't work for making cheap vacuum cleaners To support his point, he makes the unfounded argument that research into walking robots is holding back the rest of the robotics field.

    My point is that he's a short-sighted fool who is ignoring the fact that vacuum cleaners are not the end-all-be-all of robotics, nor are wheels always the best method of locomotion. My suggestion that he lose a leg (or have both broken) so that he spends some time in a wheelchair was a way of pointing out one of the most desirable outcomes of the research on walking robots; replacement of missing and damaged legs for humans.

    A bit extreme, perhaps, but consider the end result; the CEO who thinks that wheels are better than legs would suddenly have to contend with being in a wheelchair (at least for a while) and would get direct experience with just how limited wheels are and how versatile legs are in comparison.

    So maybe instead of losing a leg, he just breaks them both and has to be in a wheelchair for a couple months.
