Whyi can't figure out how they came to this simplification. How does x^y turn into something with lnx?
Please help.

>mfw I just started University level Mathematics last year and the professor actually said "Now, this technically isn't 'correct' when taking into consideration mathematical axioms but for the purposes of solving this problem we're going to have to forget about those."
When did you realise science and maths, like any other human practice, is just a method of getting by in life and is literally no different to astrology?

This. A lot of the stuff you learn at first is how to do the work (math). Later you start to learn why you can do what you do in that work. (In a nutshell)

Words like "fact" and "truth", are pure fucking cancer.
How do you deal with people who are ignorant of their own subjectivity, yet claim there is some sort of irrefutable magical quality about their claims called truth or fact? How do you not go insane from seeing people so blindly accept shit without even beginning to question its validity and the validity of their own opinions?
Fuck it fucking pisses me the fuck off how so many people in the West seems to be ignorant of how they're living in a fucking dream world.

So I suck at math and I don't even know long division. I'm still endlessly fascinated by science, and I'd like to know some science books that can explain to me some scientific concepts that I can understand without math, to the same degree that any scientist could. I am especially interested in physics.

Don't assume the direction of causality; perhaps something else changed them, and they took acid to escape from the dispair of their descent into brainletation.

I've never seen it discussed but it definitely it's a very interesting are albeit with very limited job prospects in my country.
Paradoxically i've never met a geography major myself but i'd be curious if anyone ever studied it.

I think there may be a way to completely protect us from the threat of nuclear missiles.
If an ICBM were to be fired at America, we have the technology with all of our radars and satellites to pinpoint the exact location, speed, and direction of the incoming missile. This could allow us to fire a defensive smart missile that would receive data from our sensors and track the incoming missile and collide headlong, destroying itself and the incoming missile 50,000 of feet in the air.
Of course, there's the risk of nuclear fallout happening over the continent, and this is where things get a bit tricky. If there was someway by the energy of the colliding missiles to neutralize the unstable isotopes within the incoming missile, then it would be harmless. The 2 missiles colliding would have to constitute a nuclear reaction, and there must be some special thing inside our defensive missile to neutralize the isotopes. Maybe it splits the unstable atoms into smaller and more stable pieces, I don't know.
What do you think?

There is always Gödel's ontological proof if you need a mathematical proof of God's existence.
>Gödel axiomatizes the notion of a "positive property" for each property φ, either φ or its negation ¬φ must be positive, but not both (axiom 2). If a positive property φ implies a property ψ in each possible world, then ψ is positive, too (axiom 1). Gödel then argues that each positive property is "possibly exemplified", i.e. applies at least to some object in some world (theorem 1). Defining an object to be Godlike if it has all positive properties (definition 1), and requiring that property to be positive itself (axiom 3), Gödel shows that in some possible world a Godlike object exists (theorem 2), called "God" in the following. Gödel proceeds to prove that a Godlike object exists in every possible world.

Illogical. Only one thing can be at a given point in spacetime.
