/sci/ - Science & Math

Pros of Laser:
>invisible
>speed of light
>impossible to dodge
>no need to calculate for ballistic trajectory, wind direction/velocity, mass of the ammo, Coriolis effect
>batteries are lighter than ammunition
>batteries are cheaper than ammunition
>batteries can be recharged via solar and wind.

Cons
>susceptible to the environment
>leaves thermal signatures
>close ranged

Objectively speaking, the pros completely outweights the cons.

Have any of you cut anons had any experience with it? I've been looking into it but I dunno how long it will take, what tools and resources I need, etc.
Dunno if this is offtopic so general penile physical health discussion is welcome too.

is there more than 3 physical dimensions?
how do you describe or represent more than 3 dimensions with math or geometry?

So linear algebra and intro to proof, just how hard are they?

Projecting?

What is cohomology and why should I care?

>/sci/ here. just learn that infinity and the real numbers don't exist and you'll be a better mathematician than 90% of today's phds.

have you invented any mathematical notations, anon
how do they work?
what do you use them for?

Do you need to take note when you are reading a (large) book? If you do, what is the efficient way to take note? Listing? Mind mapping?
I have never been taking note in any course in my uni, but recently there is a course that took my interest, but the book is almost 800 pages.
I was afraid that I can't really remember everything, but I have never ever taking note before so my current note look like a fucking mess.
