Lets hope they're benevolent overlords.

It's obvious the transhuman revolution will happen in east Asia. You better prepare.

If you had the ability to 100% memorize and understand inside and out every textbook in your undergraduate curriculum would you be on the same level as a professor of that field?

its true that a book is the authors ideas on paper (in case of some great novels such as 1984 or 451), but the case for academic textbooks that are meant to compile internet information into textbooks, so no, you will be not be smarter than your professor.

Let's talk QFT /sci/. Say I have a Lagrangian [eqn] \sum _{ j = 1 } ^{ 2 } \left [ \frac { 1 } { 2 } \partial ^{ \mu } \phi _j \partial _{ \mu } \phi _j - \frac { 1 } { 2 } m^2 _ { j } \phi ^2 _{ j } \right ] + \frac { \lambda } { 6 } \phi _1 ^3 + \frac { g } { 2 } \phi_1 \phi _2 ^2 [/eqn] And I need to compute the 4-point correlation function [eqn] \langle 0 | T \left [ \phi _1 ( w ) \phi _1 ( x ) \phi _2 ( y ) \phi _2 (z) \right ]| 0 \rangle [/eqn] Basically, how do I compute it? I've found the generating functional, [eqn] Z=e^ { \mathcal{ L }_0 + J_1 \phi _1 + J_2 \phi _2 } [/eqn]Is it now just a case of acting on it with [eqn] \frac { 1 } { i } \frac { \delta } { \delta J_1 ( w ) } \cdots Z[J] [/eqn] But I'm pretty lost at this point, which is annoying me since it seems like one of the easier parts, but it's the one I'm having the most difficulty with.

Energy is the ability for a force to displace an object a certain distance isnt it? And forces are vector fields. So energy is the displacement in a vector field. I think

Yeah, before 0% of blacks got into university because it was illegal for them to have an education.

Now like 10% do because they are allowed to have an education.

Wow, changes in laws have effects in the real world?

Nah, more like 10% +-5% but they hide it well because they don't want to look like autists and never have a gf

Just look at financefags at /biz/, they work with some company but they will just talk about investments instead of formulas and shit since that's part of their job but they still like it (i think)

Get into math clubs but there's a risk of too many autists to handle for you

For what end? If you are thinking about taking it up you should ask professors. I'm guessing you are in high school so you can also ask your science teachers about it.

What would happen if I were right outside the event horizon of a black hole, stuck my arm past the event horizon, and tried to pull it back out?

Assume my body is tethered to something far away from the hole so I couldn't actually be sucked in.

your arm would be ripped off

Even if your arm would be of the strongest metal known to man (diamond), it would be torn apart at the sub-atomic level. There is no rescue once it's passed the event horizon.

You probably wouldn't feel anything. It's just a surface where even light can't escape.
