Totally misread the question, I guess.

We don't have any video footage of the moons, but landings are successful. Again, we'd have limited solar power and tremendous delay times.

No. If you're refering to rover-like vehicles such as the ones we've placed on Mars, they won't work on the gas giants for a few reasons.

>Immense gravitational differential.
>Limited, if any, attainable solar energy at the gas cores due to the skies.

And even if the first two could be dealt with,

>Massive interferance from gas skies.
>Tremendous delay in communications.

Sure it will one day be possible. Not today.

Relativity, perhaps.

Industrial Engineering? I'm a ChE, and we had a name for you IE's back in college: Imaginary Engineers.

They're better at physics and math than us, but physicists rarely apply their findings to advance the state of living. Mathematicians don't give a fuck about why or how his car works, he just sees it as a series of mathematical equations and probably doesn't know what a Joule or Calorie is.

You beat me to it.

Direct Democracy does not work when the nation as a whole would be biased toward what would work best each individual state/county/city/person instead of the nation, first and foremost.

For example, New York and California are the most populous states, how would you feel if the opinions of New York and California controlled the nation and could ignore the opinions of the other 48 states?

There are three idealistic forms of governmet: Monarchy, Socialism, and Democracy, and yet the Republic is the most balanced and successful of the three excluding biblical monarchies.

A visual way to look at this is to draw a cube.

Each pair of faces represents a single direction, probably what you recognize as x, y, and z.

Now draw a few more cubes in a line.

Next, place a line next to the stack/line of cubes, and call this line Time (t). The first cube you drew represents three dimensional space at the first time interval, the second drawn cube at the second time interval, and so on.

Neither space nor time are moving, but rather the cubes represent snapshots of space at each time interval. If you're confused, go get high, it will help.

This is not math. This is intuition, and it's fucking wrong. The answer is correct, the method is wrong. I'm done explaining this. My professors would have failed me if I answered with this bullshit.

>>3095635
Yes, it's correct. It's how applied science defines one over infinity.

Can't speak for mathematicians... they define values as they go.

>>3095615
You are fucking wrong, shut up.

>>3095604
It's infinity.

The answer is zero.

Zero to the negitive first power is an undefined and infinate value.

One over an undefined and infinate value is zero.

Wrong, it's purely philosophical. It's a boundless entity encompassing one or more undieing extremes in any number of dimensions or quanta.

Maple/MatLab/MathCad that shit. Fuck doing this by hand.

I'd give you the answers but I do not have a working version installed on this computer.

The bottom right equation is

O3 + O- > 2 O2.

The free ion is the result of a catalyst that has fragmented in the solvent and then reacts with the Ozone to form two oxygen molecules. There are hundreds of possible catalysts.

I see a lot of people getting two things confused.

0.999 repeating does NOT equal 1.

lim x->inf {sum[(9/10)^i], i=1..inf} = 1.

Yes, the LIMIT an equaltion that can be written as 0.999 rep. is equal to one. When it comes to mathematics, numbers and equations do not lie and are not confusing, only the idiots who write them are.

>>3069478
Yeah, substitutions works, just like you said.

x=t+4 [=] t=x - 4

so

y=t^2 becomes

y=(x - 4)^2,

a cartesian system.

For a magnetic field "M" to propel a body "A" it must be anchored to a seperate body "B."

The OP's image shows that the magnetic field "M" is trying to move body "A" and is also anchored to body "A", hence creating a net zero magnetic force on the macroscopic body "A".

TL;DR: If you don't get it, this board is not for you.

Chemical Engineer.

I did it for the science and the cash.

xkcd dot com slash radiation

We recieve more radiation from the stars in the universe than we do from all of our nuclear power. You still cannot survive more than 4 or 8 sieverts at once. Accidents happen, but there are less deaths due to nuclear power than to coal mining or drilling for oil on a per unit time basis.

Suck it.

We find junk food delicious because it has lots of calories. Early man couldn't always garentee their next meal and would eat lots of fats and calories to ensure they had enough energy until the next kill. Our bodies are still programmed to want more calories than we currently need to sustain life.

OP is a troll or a moron.

They work just like U-235 reactors only the fuel is much more sustainable and available and the way it works once dissolved in the liquid flouride ions will allow it to be self regulating in the sense that it will heat and cool itself. You can build it so that if the system has a power failure the fluid will automatically transfer itself to a cooling reservoir.

Some guy in Tennessee got a grant for building one of those babies. I'm trying to get him to hire me.
