They aren't even used for that

Would you consider that to be Machiavellian?

So...Google Duplex just in.

Some say Google have created a deceitful AI insofar as its aim is to trick real people, namely business owners into believing they are conversing with a human. Except the receptionists of the hair-salon, or the dentist etc., will of course also be AIs, along with the hairdressers and dentists themselves.

Unlikely, that's a rather nebulous qualifier. I would consider it to be at least manipulative, and not without potential danger.

It it takes the time T seconds to accelerate the ship from 0 to 1 mile/hr then it should also the same time T to accelerate the ship form 1 to 2 mile/hr. Then the energy required measured in units of propellant should be the same pT in both cases. Yet the second case adds more kinetic energy to the ship than the first case. What's wrong with this picture?


PairTheBoard
One needs to be thorough about this. Basically its correct that from the perspective of of constant fuel used the rate of energy consumption is constant or nearly so or can be made so easily. But how much goes to the ship?

What is happening there in a spaceship is the conversion of chemical or nuclear energy to kinetic energy of the exhaust particles or ions or photons ultimately in order to gain momentum in the opposite direction.

You may think the rate is constant but the delivery of energy to the rocket system is not constant if you follow the evolution of the process say like in the rocket equation.

You need to account for the kinetic energy of the fuel also that is non trivial if it is to affect non trivially the momentum of the main ship.

For example over time the kinetic energy of the fuel in the earth system or the laboratory inertial system appears to be changing with time. The fuel initially moves to the left with -v but over time this gets smaller as the rocket gains speed/energy. So the rocket gets a larger part of the released energy than earlier as the exhaust particles get less by coming out as -v+u now. See the difference between 1/2*m*v^2 vs 1/2*m(v-u)^2 as u increases. That implies the rocket system gets more of the share over time.

When the fuel comes out at such huge speeds (eg 4km per second for chemical and 500 km /sec for ions even or more) a little reduction of them has significant impact in energy.


Imagine i send 1/1000 of the rocket out with speed eg v=4000m/sec in the rocket frame (always the same exit speed there) and i gain momentum that means i have now a speed

M*u-m*v=0 => u=1/1000*v. or v= 1000*u

The kinetic energy of the fuel is 1/2*m*v^2 or 1/2*1/1000*M*1000^2*u^2=1000*1/2*M*u^2. Oh wow you may say here. That means the kinetic energy of the fuel is like 1000 times the kinetic energy of the spaceship that is 1000 times bigger in mass but it wont matter in that sense and in fact the opposite.


So the vast majority of energy consumed is going to the fuel in order to get the momentum gain for the ship.

Over time the fuel appears to be coming out with less speed in the laboratory frame as the spaceship gains speed and eventually it may even appear to come out with nothing leaving all the energy to the ship. So the kinetic energy of the fuel declines and the ship's increases in time as expected naturally.

Looking up the history of porter lead me to a down wiki-hole.
Are Londoners aware that they had a gin epidemic? It's a respectable drink now. Tastes like leaves.

Well this one, by Hogarth, is called Gin Lane:



Looks like this Hawksmoor church on the horizon:

I enjoyed a pint of Nightmare porter in Wetherspoons this Sunday lunchtime.

I had a gin phase once. And, generally, it's best described as a phase. Never a life choice. It lasted 3 weeks.

I've got on a kick of having gin-n-tonics in lieu of* beer recently. I'm under the impression that it made no distinguishable change to my personality.

As an aside, I approve of my little brother's choice of a husband.

*"in lieu of" is Scandinavian for "as a precursor to and without a reduction of the latter"

Re: SMP Life is Being Drunk -Random Content thread

I approve of your choice of gin-n-tonics as supplemental with your beer consumption. That your personality is stable can be taken as a good thing. Others may have a different opinion.

Re: SMP Life is Being Drunk -Random Content thread

I had what can only be described as an indulgent Stout the other night. Went in tasting like bourbon, then went down like 13% alcohol level chocolate milk. I guess it was worth 12 bucks. That's like 6 four locos though.

Re: SMP Life is Being Drunk -Random Content thread

A potential hurdle for a moon bar is moon dust. Apparently normal erosion doesn’t happen there so you have fine particles that cut like glass and get into everything including vacuum seals.

Is there a solution we can think up to combat this? I’m thinking of the eroder 5000 that you run around like seeding your lawn before building structure. Or maybe settle in caves but that’s going to screw up the nice view

I'm starting to connect the dots. So far I have 1 dot.

"Plato's Cave" would be a better name for the moon bar in this case. You could have projected shadows of the outside world on the cave walls, with fire pits as well.

I know that this is the wrong place for a serious answer, but any habitable thingamajig we put on the moon would be more like a clean room than a clean room due to the extreme positive pressure differential.

Re: SMP Life is Being Drunk -Random Content thread

If a species expects to live as long as our galaxy lasts, must it colonise the galaxy?

Is it possible that a Kardashev scale type 3 civilization exists in the Milky Way while we are oblivious to its existence?
