when are we ever going to build a spaceship in space?

>fig1. a case where the square packing of circles is more efficient than a hexagonal packing
q1. at what minimum number of rockets does the hexagonal packing become more efficient?

Scientifically speaking, where does the week come from? does /sci/ know?

The year comes from the sun, the month comes from the moon (adjusted to align with year), but there is no astronomical reason for 7-day weeks

>Super easy to manipulate antivaxers.
Uhhhhhhh....

Frog/Snails eater here. Signed for a PhD in one of the top univ in Asia to buy myself 3 more years of (((freedom))) however I have no idea what is a PhD. Seems like I just need to go full autistic during 3 years on my subject but it can't be that easy is it ? The field is deep learning

I hate math. I have pretty good mathematical intuition and a strongly analytical mindset, but I just can't handle mathematical notation, on a purely psychological level. As soon as I see it, my eyes glaze over and my mind stops trying to interpret the information. It just looks like a schizo symbol salad and the mere thought of trying to decipher it, immediately tires me. Why do you little sinkers always use single letter variable names? Why do you use such obtuse syntax and rely so heavily on operator overload? Why does mathematical notation look like a fucking APL program? Unfortunately, I find myself in a position where I need to get through a bunch of books full of your stupid notations. How can I cope with this?

Physicists solve problems faster. and are better in doing Mental calculations on spot.

Mathematicians are slower, spend more time and lines to proof things with an often unnecessary and pedantic Rigour.

Physicist answers are more concise with fewer lines.
While mathematicians are too verbose and love to waste several pages to solve a problem that just need a few lines.

>finish math problem
>think to myself the result is beautiful
I think I caught the autism.

How do I become like one of those Putnam/Olympiad math-whiz kids?

why is it so fucking difficult to find a thesis supervisor? i just want to graduate my shitty college but it is starting to seem impossible.
>job market is ded, cant find thesis positions
>come up with my own topic, every professor I ask couldnt give a shit and ghosts me

Can u prove that pi is infinite?

What if pi is not infinite but is a giant number that can't be calculated?

Is there really anything special about the axiom of choice? It seems trivial.

From zero to engineer graduate level math. Where I start? and how much time would it take? Post books, video channels, memes, etc

How do this happen anons ?

how do i do this question
If p⃑ = q⃑ × r⃑, then determine the value of (cq⃑ + kr⃑) ∙ p⃑

>tensor
>operator
>spinor
a lot of thinking, still don't get it

>30k seems about righ
thanks, thats was the only thing i was looking for. sry for bad wording in my question. case closed.
thx sci!

Great minds have produced great technology but the harsh reality is that operation of that technology over the long term will be conducted by staggeringly normal minds within ordinary, flawed, ultimately unstable societies.

This is a rational basis on which to expect nuclear power to always lead to disaster.

Nuclear proponents are invariably naive morons that believe because their chosen cause is OMG PEAK SCIENCE any dissent must be ludditism.

Nope, we just understand more about human behavior than you autists.

why dont we use gambling in schools? like you create a gambling type of game where the students know the rules and odds. They put down a bet, depending on how they do on a test they get 2x their bet or lose their bet. I would never fail to study if that was the case i think i would get straight As..

What does it mean to be Somali?

If it means to be born into Somalian, then there are white Somalis and black Germans, and there's no genetic component. But people argue that race is genetic, so this can't be it.

If it means to have a certain DNA sequence, then there are Somalis who have never set foot in Somalia, and there are people born and raised in Somalia who aren't Somali. That tells me we should be using a different word.

If it means to have ancestors who were Somali, then you have a chicken-and-egg problem, because you can't show us the first Somalian.

If it means to practice the cultural rituals of Somalia, then anyone can become (or stop being) Somalian at any time, just by changing their behavior. Which is kind of silly.

There's no definition of "Somali" that doesn't fall apart under basic scrutiny. Apply to other nationalities as needed.

If I'm alive now, how come I wasn't before and won't be later?
