Proctoring a physics 1 exam and seeing students do both these and curling their fingers around (thumb in direction of current, curl fingers around direction of magnetic field) was always very humerous to see.
Naive, perhaps, but if a company advertises a service, they better fucking deliver on that service. Sure, I wouldn't store all of my important documents solely on a cloud service either, but let's not victim blame the guy here who paid for a service and was not given that service. Google's Enterprise plan promised unlimited data; whether that's 10 GB or 200 TB, that's not for us nor Google to judge. Unlimited means unlimited. And in an article linked in the OP, even customer service seemed to assure them that it was indeed unlimited, with no cap. And then pulled the rug.
And on top of that, according to the article, Google emailed them saying their account would be in "read-only" mode, as in, they could download the files but not upload any. Which is fine enough-- until Google contacted them saying they were using too much space and their files would all be deleted. Space that, again, was originally unlimited.
Judge the guy all you want, but don't blame him. Fuck Google, full stop.
I have tried saving before bed and drifting when turning corners. And on a similar note, thanks to Factorio, I swear sometimes I can see belts on my floor.
Then the arm could slide the magnet upwards to detach, reposition it, and repeat.
This would work, but this is the point where you'd need to involve an external energy source. If you move the truck-magnet-arm system such that the whole system reaches a steady state and the truck has "moved" (relative to an outside observer), to continue any motion, you need to disturb the steady state to reposition the arm and create a new resting point. Doing so would require energy. From a battery, or an engine, or whatever, but you need energy from an external source. And so we're right back to where we started: instead of all this jazz, why not just spend energy to spin the wheels instead?
A mug has one hole, as do a donut or staw. Topologically speaking, the "hole" you put your liquids in is not a hole, as it does not go all the way through to the other side. The handle is the only hole.
I've always long believed that this is the single most interesting video on YouTube. It's so well written and well explained, and every time it pops up, I watch it in its entirety. Such a fantastic channel.
