Its only me that thinks /r/Futurology/ became a piece of shit?
I used to lurk there to know about the latest tech advances but nowadays if you scroll past the frontpages the only topics are:

- Elon Musk cock slurping
- muh clean energy
- muh universal basic income
- hurr robots will replace ALL jobs
- other political shit in general

It's the same way with every science/technology related subreddit.

The whole system of voting promotes retarded comment to the top while the people who actually know shit get downvoted.

The submissions themselves also trend away from technical info towards dumbed down pop science journalism as the subscriber count grows.

why is zero raised to zero undefined but every other number raised to zero equals 1?

Who comes up with this shit and why do we listen to them?

When working with integers, 0^0 = 1, but when you extend the definition of exponentiation to real numbers the equality doesn't hold anymore because x^y is not continuous in (0, 0)

Why does the universe exist? Does it serve a purpose or does it simply define other purposes, being purposeless itself

my friend, stay true to yourself and try your best.
The skills you learn from taking the road less traveled will make you more valuable!

i graduated with a 2.87 gpa, but got a job before i even graduated. It was the first job i had ever gotten without even knowing anybody in the company.

i showed them i worked hard through other means than my gpa

I want to code my own 2D games in libgdx.

How much math and physics do I need to know?

Can you at least give me a list of shit I can google?
15 posts and 1 images submitted.

I've made my own games using C++, and the only physics I used was simple kinematics equations. You might need a little bit of trigonometry for moving objects, but you don't really need to understand how it works.

>math
2D gamedev is normally not maths heavy at all. It's all about logic and structure. You might be slightly disadvantaged if you can't do basic algebra and use trig to solve right-angled triangle problems.

Learning what vectors are would be useful but you only need an entry level explanation of them and you don't need them to get started. Don't overcomplicate things.
>physics
Don't write your own physics/collision detection, use Box or Chipmunk. I suppose knowing how to apply basic equations of motion might be helpful if your game involves e.g. throwing objects around.

>a list of shit I can google?
What level of programming can you do already and what's the highest level of maths education you've had? You might be essentially good to go already.

What do you mean?

Enhancing every function at will, i.e., turning off other functions while using logic, moving weight etc.

Ok /sci/ my PI just slapped some RNA-seq data on me and I have no idea what to do with it. How do people typically go about getting meaning from the differential expression lists?
