You'd need a second generation nuke for large yields. Pic related. 1 Gt nuke would radiate most of energy to space. Not really useful.

For handgrenade sized nukes you'd need fourth generation. Much more applicable to warfare. Pure aneutric fusion would be good for EPPP applications and conquest of the solar system.

Too bad nuke research has been gutted since the ruskies went down.

There were designs for 1 gigaton and 10 gigaton bombs in the 50's codenamed GNOMON and SUNDIAL.

The 1 GT one is assumed to have been the primary for the 10 GT one.

I don't care if you're doing signal analysis or whatever, the world is REAL, not COMPLEX. Your scale will never tell you you're 50+50i kilograms. No observable ever can take COMPLEX values!
This means that to describe the world which is REAL, we shouldn't use COMPLEX numbers. It's not REALITY therefore it's WRONG.

With that respect, your scales will not tell you that you weigh a negative nor an irrational either. Different sets of numbers have their different corresponding applications. Obviously all of them don't pertain to everything - doesn't make them obsolete though.

Lul'd a little. It's sad that there really are people who don't understand that there's more to math and its relation to the real world than just the real numbers.

Is eternal life a possibility for anyone alive today?

I think we will develop some form of biological immortality within our lifetimes. If we don't live naturally long enough to get true immortality, we will at least develop some method of life extension to allow us to live that long.

Is it just me that gets more terrified by the thought of being unable to die one day moreso than being terrified of the fact that I will die someday? An eternity of suffering versus just suffering for a little while? Being dead sounds pretty relaxing in comparison to immortality.

It's a tool to roughly estimate one's efficiency in understanding and solving problems in science.
However, many people use it to estimate one's actual skills, knowledge or absolute limits in what he can ever archive. That's not how it works.
>>
>>8337758
1. There are multiple types of IQ tests
2. They're all over the place
3. Some are controversial
4. Even the generally accepted tests are fallacious as they give equal weight to inductive, abductive and deductive reasoning

foucault

>>8337513

Grothendieck was quite straight, and a "proven commodity" in the sexual marketplace: he had five children by three different women. That's some evolutionary fitness right there. Foucault, meanwhile, was gay as a gymnast on shore leave, dying of AIDS in the 80s. Grothendieck would live about another 30 years, himself pushing 90 at the time of his death.

Both men were born within about two years of each other, so you could just about say that they were birth cohorts. Each man also spent important periods of his life around Paris and the ENS, and as academics, bounced around colleges. They both had batshit-leftist political orientations as well.

The similarities go much deeper than the polished, bespectacled cue-ball.

Is scientific discoveries the only things that can give meaning in your life? Why is it that once you take away most attributes from a persons life they become depressed and meaningless?

For example, I am on a holiday break right now from uni and I hate to death the fact that I know I am working towards my financial independence and freedom but once i've obtained that I'll be in the same scenario I am in right now, being bored.

Why is it that we know bestowed meaning is nonsense but also self derived meaning is nonsense because its self derived.

Why do such contradictions arise in our brain, what happens when no one needs to work anymore.

Do you guys remember when you were younger and being captivated by the simplest things such as in elementary school you had to make your own pot plant and take care of it? Can such pleasures still exist after being an adult?

Drugs. Take your pick. Alcohol, cocaine, weed.

Family. Get a wife and have children.

Work. Work for the sake of working/keeping busy. Work is freedom.

But seriously you need to try LSD. Go trip your balls off and you'll find that the childlike wonder is still inside you.

Why do most physicists on here seem to really hard deny personal perspective being of any factor in our understanding of physics?

>undergrad for BA in chem, BS in phys (double major)

Maybe it's just a coincidence, but every time I bring up this problem, every physicist here goes nuts and says what I'm saying is retarded for reasons that are never explained. Basically the idea is that information is a physical concept (as in a real thing with units that can be measured). And as information receivers (smart people who study science), we are subject to certain physical laws (if information can be measured it should obey mathematical/physical laws). So when we research quantum physics and find that our answers indicate that our personal perspective changes the result (i.e. double slit experiments and others like it) why is it not rational to say that the unknown physical laws of information are playing a part here? And why do we stretch the physical definition of existence to say that just because we don't have the information of an object occupying a certain state, that the object must occupy every possible state? Or put in other terms, why do we believe our consciousness alters the universe as opposed to this simply being a problem of the unknown functionality of information?

I don't know what you said, but if you prove something is real with an experiment every physicist will take you seriously.
>>
>>8337418
If information was the cause for the funny results of double slit experiments, it would basically explain that a lack of information reaching our brains is responsible for the mismatched results.

I'm saying our personal perspective isn't good enough to study this brand of quantum mechanics, not without introducing a new study of physical information.
>>
>>8337402
1. Information isn't special, it's just regular matter that interacts like other matter under the laws of physics.
2. Collapse of a quantum system is due to interaction with the system. This can be interpreted as information, but only in hindsight.
3. There's no reason to suggest that matter used to convey information follows laws any differently than matter that isn't. (Because all matter is a form of Information)

People get salty because you're attributing a metaphysical interpretation of fundamental laws. This has been done to death and you should know better.

Not for those things, but he's certainly a con artist when it comes to science.

>muh simulation

Literally rule 1 of science is falsification
>>
>>8337387
He's actually selling the electric cars, though, and when people buy them they actually get the electric cars and are satisfied with them. When you promise something, and then deliver people what you promised but only if they give you money, that's not actually a 'con'. That's called a 'business'.

That's like the time I conned people out of their money by telling them I'd suck their dicks for $5, and then not sucking their dicks until they gave me $5.
>>

>strict falsificationism
go fuck yourself
If a simulation theory predicted yet unobserved result with an extremely high precision we would favour it.
The same way discovering Neptune based on Newtonian mechanics reinforced it as the favoured model.

>regularly failed his exams in school while he concentrated on reading Legendre's Geometry cover to cover.

>Péclet wrote of the young genius "He knows absolutely nothing. I have been told that this student has mathematical ability; this certainly astonishes me. Judging by his examination, he seems of little intelligence, or has hidden his intelligence so well that I found it impossible to detect it"

> Galois also failed to gain admittance to the École Polytechnique not once, but two times. During the first of these examinations, in 1829, Galois was so frustrated by the inane questions that he vented his anger by throwing an eraser at his examiner

Is it possible for a person with an Internet connection to become an expert mathematician?

With most scientific disciplines, you need some special resources or materials that the average person cannot obtain either for legal or financial reasons. But does math require anything like this? There are tons of resources on the Internet (Khan Academy, open courses from MIT or Cambridge, a wealth of used math textbooks that can be bought on eBay, etc.)

So let's say a person of average means embarked on a mission to become an expert mathematician... What obstacles would they run into as far as resources?
