million points of failure and no abort system does eLon not care about human life?

My professor sent me onion links when I asked for resources related to my thesis.

>20 years between Apollo 1 and Challenger
>17 years between Challenger and Columbia
>mfw we're almost due for another space disaster

Scientifically speaking, what is the probability of a deadly failure?

>Another good source is raw Mars rover pics from NASA.

Those have UFO sightings?

Are they still inside?

its literally high level nuclear waste from the 1950s.

My diet today only consisted of Great Grains, a bunch of cherries, and I think 2 strawberry popsicles. After I ate the popsicles I get this headache and it won’t seem to go away.

Furthermore, did I just turn myself into a diabetic, /sci/?!

>tfw 0.999999999....*0.999999999...=1

How do you even get hired at this places?
Do you have to be putnam fellow tier?

>When you sleep your brain reboots, killing the literal you. when the person wakes up again, its a new you with the old you's memories.
Is this true? Is this a scientifically accepted theory?

How long did /sci/ spend on their dissertation? What score did you achieve and what was your major? Mine is due at the end of next month and I only just started and it's finance related.

Am I fucked considering I'm behind my classes and exams begin in 6 weeks so got that to study for as well?

I need some academic suggestions /sci/.


I got my BA in history because it was easy to do it while working full-time. Now I have 4 years of free schooling because of GI Bill. I am thinking of going to school for international affairs but I am having second thoughts. Should I go back to school and get a STEM BS or take some community college classes for dental/pharmacy school? Or is there something else I should consider? I don't want to waste this schooling opportunity.

>Hopefully that same luck holds out long enough for us to do something to increase our odds.

Anyone get kinda spooked by this? Just the fact that Earth isn't necessarily a stable, safe planet but could get wriggedy wrecked by any random ass comet or spoopy space cylinder or gamma ray burst.

And we're still not on Mars yet.

who else here /radiophobia/?
i am going to buy a geiger counter to check my house for radon gas, but i feel like it will eventually lead to checking everything including my food obsessively before each meal.

>test in 14 hours
>haven't done a single practice problem

Ok let's see if you guys can help me with this one.
I was computing Euler-Mascheroni constant with an algorithm I found in math.stackexchange because it seemed simple and had convergence of order [math]\mathcal{O}(n^{-4})[\math] and computational cost [math]\mathcal{O}(n^{2})[\math]. The formula is
[eqn]\gamma = \lim_{n\to\infty} \frac{1}{6}\left(\frac{1}{n^2}-\frac{1}{n^3}\right) + H_n - \sum_{k = n+1}^{(n+1)n} \frac{1}{k}[\eqn]

It's great in that you reach fast convergence up to n = 1000, but after that for some reason I see divergence (for example n = 20000 gives a result of -2, n = 2000 is less precise than n = 1000 etc.).
My question is: is this series inherently divergent because of the second "harmonic", or is it just my code that is failing? I hope it's the latter.

i...i'd like to stay away from the whole croats-serbs thing because it doesnt help at all in this situation
and i'm more of a passive aggressive person..it would only work for me as an allegory

>that feel when reading about vacuum decay

Tell me about your favorite prof

>graduated with Masters in 3 years, went on to Top 5 Math PhD program
>he used to do topology on his own time freshman year undergrad for fun
>he didn't want to take undergrad modern algebra before grad algebra so he did half a textbook's problems between semesters
>not even autistic at all

How can mortals even compete, I don't even go to a good school

>Harvard Math 55 students are doing what you're doing your senior year

why the fuck is it this warm in february /sci/

>1st semester
>math exam on saturday
>did good with homework so far
>understood all topics
>doing exam level exercises with solutions
>they are hard as fuck
>look at solutions and don't understand how they expected me to figure that out

Welp, is that gg?
