    If 9-yo could understand relativity then the industrial revolution would have occurred 600-BC !

    1. The industrial revolution was not based on relativity. It was based on Newtonian physics.
    2. Plenty of 9 year olds can understand that F=MA.
    3. Understanding something is not the same as discovering it. Plenty of big discoveries are "obvious" in hindsight.

    They will probably have a very hard time understanding the magnitude of the numbers involved.

    So what? You don't have to understand scientific notation to know that you can vaporize Klingons with anti-matter.

    When kids ask questions, they just want a quick overview. They aren't expecting you to read them a PhD dissertation. Although that might be effective way to get them to go bother someone else the next time they have a question.

    Relativity, spacetime curvature, and mass-energy equivalence are not beyond a nine year old's ability to understand. They aren't going to be able to understand all the formulas, but they can get the gist of the concepts.

    If you don't want to explain it to your kid, there are plenty of great Youtube videos you can point to that explain all this stuff really well in kid friendly terms.

    Youtube and Wikipedia have made parenting much easier.

  4. "Ethical hackers"...

    Indeed. You have to admire criminals that are willing to accomodate their victims' ability to pay.

    Also, ransomware has some positive benefits. For so many areas of computer security, the cost of poor practices is externalized onto the innocent. This is true of data breaches, insecure devices used as spambots, etc. But with ransomware, the cost lands directly in the lap of the people failing to secure their systems and failing to run backups. So ransomware directly incentivizes better security practices that benefit everyone.

  5. Just because my browser has a built-in password manager, doesn't mean I use it. I use Keepass instead

    You aren't using it because you are already using something else. But for 90% of the public, if a popup asks "Do you want Chrome to remember this password?", they are going to think "Sure, why not?". But if someone later asks them "Are you using a password manager?", they will say "No", because they don't even know what that is.

    The main problem with syrup in Canada is surpluses. . They have production quotas to prevent overproduction and support higher wholesale prices.

    The world is not going to run out of pancake syrup, and stupid alarmist articles like this are counter-productive at getting people to take climate change seriously.

    More importantly, Trump humiliated Wall Street's chosen candidate (Jeb Bush) in the primary, and then beat their back-up candidate in the general election. Since there was no "legitimate" way for that to happen, it is clear that the American people were "tricked" by criminals, or even worse, Russian criminals.

    Is it really Facebook's fault that too many people voted the "wrong way" in 2016? Who gets to decide which thoughts are "right"?

    Being excluded from promotion decisions could be one of them.

    Well, if they screw up the response to a real ballistic missile attack, then sure, delaying their promotion would be warranted.

    Perhaps it is time to question whether we should even have state-level bureaucrats assigned to ballistic missile response. Shouldn't that be something handled at the Federal level? The is especially true for Hawaii, which has near Louisiana levels of corruption and incompetence.

    David Ige, the governor of Hawaii has said this has been a "learning experience" for everyone involved, that it will not turn into a witch hunt, and no one will lose their job.

    Taking shelter can make a big difference. We can learn a lot from what happened at Hiroshima and Nagasaki. People in the open were much more likely to be killed. But shelter helped a lot more in Nagasaki, where most buildings were stone, rather than in Hiroshima, where most were wood. Nagasaki was hit by a bigger bomb (20kT vs 15kT) but fewer people died because there was no firestorm like Hiroshima experienced.

    Anyway, I think we are way past the point where anyone is going to take these stupid "alerts" seriously. I heard that less than 5% of Hawaiians actually took shelter, and every false alarm is going to diminish that further.

  16. Those robots are not cheap to buy or maintain.

    Actually, they are cheap. Most cars already have power steering and braking, so no new actuators are needed. Just some cameras and some software. Software has a high NRE, but near zero marginal cost.

    5 megapixel cameras cost less than $5 each. Beginning on 1/1/2018, rear facing cameras are mandatory on all new cars, so only the front and side/oblique cameras are an additional expense.

    Lidar is expensive (~ $5000 per car) but it isn't necessary. Waymo uses it, but Tesla does not. The cost will likely drop a lot with mass production.

    Self driving capability will add between 0% and 10% to the cost of a car.
