That's a good one OP. Obviously the car doesn't stop, but I can't solve the apparent contradiction. Im stumped

Objects never actually touch each other. They just get extremely close. There is always space between atoms.

As the bug "hits" the car, really it is just the front atoms of the bug are repulsed by the atoms of the windshield, causing it to slow down. Again, they never actually contact, just get slower as they get closer. Eventually the bug stops completely and reverses in a very short amount of time. The car itself never changes its speed.

>>9085710

So if you hit someone in the head with a baseball bat none of the matter actually makes contact. What kills you is the repulsive force of the atoms?

It means you have Huntington's Disease

Looks like a case of arteries. You should cut them open and take them out forthwith.

(Part 2)
I know this issue was already referred to, especially in the context of Russell's paradox (again, why did people assume that the idea "set of all sets that don't contain themselves" is well defined?), and was allegedly solved by formulating ZFC and other axiomatic systems. But the only thing these systems did was decide on "stricter" rules, without dealing with the problems itself (one can still use objects and statements that are not well defined).
I think that in order to give a truly consistent and complete math, math needs to develop a linguistic theory that deals with how mathematicians form statements and definitions. I'm not talking about logic; I'm talking about a real linguistic theory that specifies under what circumstances mathematical statements are well defined. (The bad new is that it'll probably also force math to ditch Godel's incompleteness theorems and other ideas that'll be regarded to as "not well defined").

So at this point I have to admit that I don't really know what I'm talking about - I'm not even close to being an expert. But what do you think about this idea? Has it already been done and I just don't know? Is it possible? Is it worthwhile? Do you have any suggestions to problems that might relate/counter examples to reject my idea?
Starting next semester I'll start taking courses in axiomatic set theory and advanced logic and linguistics in order to start working towards a proper understanding of the subject (with the goal of one day creating this postulated linguistic theory). Until then, I'd love to hear your thoughts!

Mathematics is a subset of linguistics. If you believe in a "True Mathematics" that exists beyond the scope of any form of language or formalized logic then you're already implicitly buying into the fundamental idea of Godel's incompleteness which is precisely THAT no formalized system of Mathematical arithmetic can prove all properties of the system.

As will all things mathematical, Godel works off of axioms, which you can think are neither pertinent or well-reasoned. One could easily argue that the theorem is not a limitation of logic and reason, but rather is a limitation of "elementary arithmetic" of distinct and finite operators. But it is a proved theorem within its well-defined scope. (And on that note there is no such thing as "proving something is well-defined." The concept of being well-defined is more fundamental than the concept of a proof. After all, proofs are the things most subject to being well-defined or not well-defined.)

Pfftt, Gödel's theorems are simply inspired by the liars paradox: "This statement is false" which is False and I can easily explain how. But more interestingly, the paradox comes from our acceptance of "This statement is True", which is also False. Better yet, I can refute the Halting Problem's proof here: https://www.youtube.com/watch?v=wGLQiHXHWNk

I will start with how the Halting Problem was not proved after I take a screenshot of the flawed proof.

imagine a function both_one(f,x,y) for f(a) either 1 or 0
if f(x) = f(y) = 1 then both_one(f,x,y) = 1

you can create now another function called paradox:

function paradox(x):
if (both_one(x,x,x)==1) return 0;
else return 1;
end paradox

Here is the problem for paradox(paradox): if both_one(paradox,paradox,paradox) is 1 then paradox(paradox) returns 0, thus paradox(paradox) and paradox(paradox) can't be both 1. And if both_one(paradox,paradox,paradox) is 0, then paradox(paradox) returns 1, then both_one(paradox,paradox,paradox) must be 1. This is a contradiction, but the function both_one(f,x,y) exists, and is easy to create unlike the function halt(function,input), so this proves that this kind of recursion is wrong

A good way of creating consistent recursion is using algebraic technique i.e:
x = 10
2x = 10 + x
x = 5 + x/2

Algebra applied to "this sentence is false" is simply:
x = -1
x = 1

In terms of sentential logic, you have to differentiate a statement from a non-statement, otherwise you end assigning True or False to sentence elements eg Chicken = True, Blue = False, without any adequate context... But you don't have to differentiate, as long as you are consistent, and this is useful when such differentiation is unpractical: you simply assign a True or False value to any sentence. Effectively, however, all true sentences will be true statements, and all false sentences will be either false statements or non-statements. Take the sentence "Is false", [to be continued]

I passed all my math courses with good grades even thought I didn't even attend the lectures. I just read the course books, solved exercises and aced the exams.

I also happen to be a CS major. How's this make you feel?

>>9082173
I've passed over 12 subjects attending less than 10 total lectures (combined).
Almost zero labs (excluding compulsory).
And literally zero tutorials.

I'm no brainlet, just an idiot.

Government work is kind of pointless right now because it has been successfully privatized. Private corporations are successfully launching satellites and beginning to build manned rockets.

The future of space travel will be commercial and will really gain traction once it becomes profitable somehow other than just government grants.

Fuck human space exploration. Human space exploration is just plant a flag, take a picture, grab some rocks, then leave. I mean it's nice and all, but what we really need to focus on is changing the way we do space.

Right now we need to ship up everything from earth, if we're ever going to live in space this needs to change. What we really need to do is get In Situ Resource Utilization working. IE using shit from where we're sending people rather than hurling it from earth.

One of the best ways to start doing this would be to mine the Moon. So unlike asteroids, the Moon is damn close. Lag time is only like a second so teleoperating robots from earth is possible. This also means we can get stuff to the Moon within days of launch as opposed to years.

Now if you haven't heard, they just found a lot of water on the Moon
http://www.nature.com/ngeo/journal/v10/n8/full/ngeo2993.html

Now water's cool for a number of reasons, we crack it into propellant, we can use it for a bunch of metallurgical processes to refine moon rock, and we can use it to keep meatbags alive

Water has been found on the Moon before in permanently shadowed regions. Except we know fuck all about permanently shadowed regions and it's hard to power a rover some place that is PERMANENTLY SHADOWED.

So this new discovery is that some rocks we have from apollo that turned out to have quite a bit of water aren't anomalous and are found all over the moon. And most importantly they're out in the sun, where we have energy to process them. The concentration of water is high enough that with a small rover like one of the ones used in NASA's regolith mining contest(https://www.nasa.gov/offices/education/centers/kennedy/technology/nasarmc.html) could potentially mine tons of water per year.

Once we have a way to make propellant, we can set up a taxi to and from the lunar surface to bring more rovers/extraction plants to make more propellant

Watch "From the Earth to the Moon" HBO series.

I honestly don't see how, in an age where the existence of a veritable junk yard of near Earth orbit satellites creates the foundation for modern communication, people would draw the line at "being able to create a container which could sustain 1 atmosphere of pressure differential." Yes, it would require a lot more fuel, but we put a lot more money into that particular pissing contest.

It just seems like an anachronism.

what the fuuuuuuu
are you seriously making this argument? Or is this bait are you actually joking

You could use that kind of logic on anything and everything at all. With that kind of logic you can't prove anything. How much proof do you need to say something is or isn't Jesus Christ how do you not see the inconsistencies with that line of though

The scientific consensus today, is that your mom is a whore.

Not even a few hundred years can change that.

with 2 lines the outer regions of the circle will have less area than the center region, so the lines have to be spaced unevenly with each other to make it an even area with the circle

Until the man's quantum uncertainty resolves itself ahead of the turtle. Checkmate.

>>9085514
well, that's that then, lads. motion is impossible, let's move on, shall we?

The space between them would reduce each time the man reached the turtles previous position, and as a result the time to reach the turtles new position would also be reduced. Even though there would be infinitely many of these checks, they would start happening so quickly that an infinite number will occur in a finite amount of time, thus allowing the man to finally pass the turtle.
