Comment Re:2 time the gravity thought (Score 1) 134

And I repeat: from TFA, mass of the planet is 5x Earth Mass. Diameter (and radius) is 1.6x Earth.

Insert 5x mass and 1.6x radius into Gm/r^2, and you very quickly realize that:

1) density isn't the same as Earth's. It is, in fact, a.25x Earth density.

2) surface gravity will be ~2x Earth (1.95+g).

The mass of the planet is only an estimate currently as that can't be measured without radial
velocity studies.
But assuming that mass I agree with your gravity estimate.
But your density is wrong (maybe a typo?), volume scales as size^3, so density is like 1.22 x Earth
for that assumed mass.

How many criminals are smart enough to think long term like this? Not many I'm afraid...

But the thing is we mainly learn about the stupid criminals.
Those (however many there are) who are smart enough to make it work we don't
know about.
e.g. if someone uses an accomplice, doesn't spend any of the money for some time
(say a couple of years), then leaves work for a plausible reason and moves
to a new area, I'd guess we may not hear of these.
And we get a distorted view of criminals because the ones that succeed are never
heard about.

I think this counts as a "known unknown"....

Why would an entrepreneur go to Australia and pay even higher taxes there than in the U.S. when they could immigrate to some country.../p>

If they are "going" then they are "emigrating" not "immigrating".

Overall, just using "migrate" is probably better as it's independent of the point of view.

So, where are all the environmentalists demanding we build integral fast reactors as fast as we can?

"Why Fukushima made me stop worrying and love nuclear power "

You will not be surprised to hear that the events in Japan have changed my view of nuclear power. You will be surprised to hear how they have changed it. As a result of the disaster at Fukushima, I am no longer nuclear-neutral. I now support the technology.

And yet I see so many vehicles in the left-hand lane on US highways weaving onto the left-hand shoulder.

Surprisingly that seems to include the self-driving car I was behind today.

At least I assume it was self-driving as the woman in the driver's seat was spending quite some time using both
hands to adjust her hair....

I had the original Macbook air which also had only one USB port (although not USB-C of course).
It was often an incredible pain having only the one port. I now have a more recent Air and the additional ports make the
machine much more flexible and useful for me. (And I use it as an international travel device for taking to conferences etc.)

The difference here is that Uber has a product. A vile, rent-seeking product built on the corpse of the American Middle Class, but a product nontheless. .

I'm finding Uber increasingly useful, as so do an increasing number of people I know who live in cities.
The drivers also seem pretty happy when you talk to them.
So, I think you're overstating how bad Uber is overall. And they may even (with luck)
have a positive role to play in making cities easier to get around and so reducing the
need for cars.
