Does G+ do this on purpose?  I've seen more "coincidences" than I probably should have.  This one's great!  Falcon 9 pointed to Mars. (I know the author says Europa, but it's Mars)

May 15th here. I'll keep a watch on the evening temps for a while and bring them in if it gets too cold.

Why is Google removing NPAPI support in +Google Chrome ?  This means Java is not supported by default in release 42.

Google has really been throwing its weight around lately. This 90's API likely needs to go, due to security issues and hanging the browser, but the handling is where I have issue. Along the lines of their SHA1 cert, TLS everywhere handling, CA killing, and cert pinning attitude. Then there is them basically forcing SPDY to be adopted as the HTTP2 standard with all its flaws.

Two of these just flew over my house at about 400 ft altitude.  The house is still shaking - coolest thing I've seen in a long time!

When those fly up over Huerfano County, all the jittery vets go a tad crazy.

This is cool.  What was 11x12 again?
Also, it's weird that this isn't symmetric (though close).  Guess we're not teaching the commutative property well enough?
 
A couple of years ago, someone collected a very nice set of data by testing pupils at Caddington Village School in Bedford on their multiplication tables and recording the percentages of correct answers. The data have been made into a colour chart that allows you to look at which products people find hardest to evaluate. One interesting feature (though I don't know how much it is just random noise) is that the chart is not symmetric about the diagonal. For example, 8x7 and 7x8 do not appear to be of equal difficulty. The numbers on the right are, I think, the percentages of wrong answers, so the higher the number the harder the question. Another interesting thing is that 2x1 seems to be got wrong occasionally (but not 1x2). My guess would be that from time to time people answer 3. 

One reason this interests me is that I have often seen people lazily saying that to learn your tables you have to learn 144 arbitrary facts. This is of course completely false. To begin with, as this diagram illustrates, many of those facts are not at all arbitrary: for instance, you don't "memorize" your 1 and 10 times tables. Secondly, the facts are not isolated: if you know what 7x7 is, for example (which many people don't, to judge from the chart) then you can use it to work out 8x7. Of course, you eventually want to be able to say what 8x7 is without thinking, but I see it as like driving a car: initially you should think carefully about what you are doing and after a while it should become automatic. For this reason, I would describe myself as a semi-traditionalist when it comes to tables. I think they should be taught, but I don't think they should be taught in the kind of pure rote way that many people object to.

Good starting point. Takes a bit more than that, but not a bad place to pencil things in.

+SpaceX was right next to our booth at the Space Symposium.  These kids are strapped in the Dragon capsule cockpit mockup and are ready to fly.  I bet they'll go to Mars!
