Will the western world every be as supportive of space exploration as it was in the sixties? The general public seem completely uninterested these days, especially now that we're almost exclusively sending robots up.
>>9149962
No, the welfare state forbids spending on large projects.
>>9149962
We already have the ICBMs perfected, no point in investing in it anymore.
>>9149962
it would take a massive paradigm shift in general culture for the masses to care about space exploration. Even in the sixties they didnt actually care about space exploration itself but rather the symbolism. Then they fucked it for good with all the deaths in the 80-90s.
>please dont delete this, there is a reason why i posted this in /sci/ thank you
I'll keep this as short as possible, here's my situation;
>I'm 23
>about to cont. education this year - (HS level education) gymnasium 1st year
>meaning ill be 28 when i 'graduate'
>(very long and depressing story as to why, to keep it short ill just cont.)
>just realized, at 23 that i am interested in science - generally
>i specifically like ALL of these; biochem, chem, math, physics, cosmology/astronomy but still didnt decide on what to pursue
>dont know that much, by now i literally forgot everything i learned in primary, im an uneducated, literal baboon, above average intelligence, basically ''WASTED POTENTIAL!''
>still dont know what exactly i want
My questions are;
1. given my situation and age, should i even bother with pursuing sci major starting at 28
2. given my situation and age, which one (biochem, chem, math, physics, cosmology/astronomy) would be the best choice for me?
All i want in life is to help/contribute to humanity doing what i love.
quality of life is also important when answering...
please answer, im hopeless

George Green become an undergrad at age 40 and did amazing things (you learn about various things he did in the undergrad courses partial differential equations and calc 3/4) so you should start if you like it enough as you never know
just do whatever you like more bro. you can always sit in/audit classes to subjects you think you'll enjoy as nobody will notice or care if it's not an upper level class with few students (worst case teacher asks you to leave)

Yes. Timeing is irrelevant, everyone's journey happens at a different pace.
>2. given my situation and age, which one (biochem, chem, math, physics, cosmology/astronomy) would be the best choice for me?
Regardless of your backround do which one you think of first. Pick the one your most interested in, that will give you the drive and motivation to pursue and follow through.
do nutritional supplements have the ability to increase ejaculate volume and power? does it only fix deficiencirs?
i have read anout zinc, magnesium, lecithin, and arganine
the only one i really believe is zinc because it is a common deficiency, but I am not a nutritionist
>>9149889
almost certainly no. Also nutritionist is not a protected title like doctor. I can legally call myself a nutritionist and so can you. Dieticians are the ones with actual training.
>>9149892
why almost certainly no?
it makes sense to me that since sperm production is expensive, there are bottleneck. but there would always be an incentive to increase production if nutrition is augmented
i am skeptical, of course. but it is something i really want to believe when i am involved with thots
I recommend a three day split, back, chest, legs and put those sperm on a dirty bulk for best results for six months. They will be shredded af coming out of your wife's womb.
[eqn] ax^2 + bx + c = a\big(x+\frac{b}{2a}\big)^2 - \frac{b^2}{4a} + c = 0 [/eqn] as is easily proved by expanding the right hand side. Hence
[eqn] \big(x + \frac{b}{2a}\big)^2 = \frac{b^2}{4a^2} - \frac{c}{a} [/eqn]
Taking the square root of both sides
[eqn] x + \frac{b}{2a} = \pm \sqrt{\frac{b^2}{4a^2} - \frac{c}{a}} [/eqn]
Subtrating [math] b/2a [/math] frmo both sides
[eqn] x = -\frac{b}{2a} \pm \sqrt{\frac{b}{4a^2} - \frac{c}{a}} = -\frac{b}{2a}
\pm \frac{1}{2a}\sqrt{b^2 - 4ac} = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/eqn]
Now we have arrived at a way to figure out values of [math] x [/math] that will satisfy [math] ax^2 + bx + c [/math]
>>9149884
ax2+bx+c = 0 that is

can anyone offer their expertise on creating a functional v2? i suppose modern electronics with newer features and more accuracy would be used via an arduino or something, but i would want to keep the engine and everything else authentic. minus the warhead of course.
>>9149833
>controlling a V2 with an arduino
nice try, kim
The machines used too make the airframe parts are ancient amd cheap relatively, tool and die, press brake, shear amd a few more
>>9149861
yeah. they were extremely inaccurate too. with an arduino mega, a gps and a phone shield you could control the v2 with a smartphone and have pinpoint accuracy. just text it the coordinates to want to hit and off it goes! i wonder why nobody has tried this yet...

I'm finding calculus I quite confusing even in the first week. I think my Stewart book isn't always clear. But, I'm probably struggling because I haven't taken any math in eight years and I never took pre-calc in high school. I have a BA in linguistics and I'm currently doing pre-reqs for a CS MS. What do you suggest I do to prepare for this?
>>9149705
Also how do I solve 15? Just like flop the shit around n whatnot?
>>9149705
>1
just offset it by 1 jesus man
>>9149705
>I'm finding calculus I quite confusing even in the first week.
Okay.
>I think my Stewart book isn't always clear.
Stewart (and its ilk) are invariably written like shit because someone figured out that students never read the textbook and rely on notes and examples like class. So you are forced to buy a $200 (or whatever) brick. It should be easy to write a good, terse and entertaining book on calculus, yet all intro calc textbooks end up being bloated monstrosities with hundreds of pages of useless text and bad examples.
>But, I'm probably struggling because I haven't taken any math in eight years and I never took pre-calc in high school.
lmao XD want a medal?
>I have a BA in linguistics and I'm currently doing pre-reqs for a CS MS. What do you suggest I do to prepare for this?
The best way to learn calculus is to do calc problems. Weird huh?
You will also need to learn trig. Knowing basic trig identities (SOH CAH TOA, cos^2(x)+sin^2(x)=1, half angle formulas, unit circle shit and a few others) is a prereq for almost every calc class.

Why are you confused by the number 1?
Take the function e^x, make it half as big, flip it around the x axis, flip it around the y axis and then move it up by 1. Basically what the Harlem Globetrotters to do my mom when I'm at my dad's house.
What's the best way to get rid of a headache. I want to work but my head hurts a lot.
Excedrin in my experience, and this is coming from someone who tried a million rx meds
>>9149612
I only get them if i wake up dehydrated. I chug some water and take a few aspirin. Aspirin works quicker on these kind of headaches, powered aspirin even better. If you have a s.o. a scalp/temple massage will get those capillaries flowing that're causing it to.
>>9149612
I take 800mg ibuprofen, 1500mg acetamenophen, and a cup of a caffeinated beverage at first onset and it usually gets id of my migraines within an hour.

If the singularity happens, humans become immortal and colonise the universe.
How many humans do you think that will be? I'm guessing 100 trillion. In the vast expanse of time this is not unreasonable.
Now what are the odds you were born in the 0.0000000001% of people before the singularity? Very low.
It is statistically almost certain that you will live forever and become a galaxy faring space god.
>>9149591
>>9149589
This is what nihilism does to you. You replaced gods with atheism, and now that you have nothing but a dark and painful existence to reflect on, you imagine utopias fueled by Science.
I do not believe people will be immortal, not replaced by robots 30 years from now. Nor I believe I'll be flying spaceships 50 years from now either.
How do you solve this using the quadratic formula?
I'm talking about 40 btw
>>9149552
It is actually impossible. That is one of the biggest currently unsolved problems in complex analysis, so important in fact that it was proven in 2007 (Tao) that if it is proven that the solution to that equation is what we think it is then that implies the strong generalized Riemann Hypothesis and the twin prime conjecture.
First rationalize (?) it.
How does /sci/ take notes when reading a textbook?

>>9150163
>>9149505
t. brainlets with books which explicitly proves everything and assumes the reader is a retard
If you're reading anything worth reading and don't have photographical memory then organized note taking is needed to work out the quirks of any math related book.
To answer the question OP. I usually just use a small left vertical section for headers of sections/theorems and the remaning page would be my notes. Then when I need to search for something I just read the left of the page.

Cheating doesn't exist on a game that's fundamentally not fair. I don't remember choosing my genetics and the environment I grew in.
Searching historic hurricane tracks, mainly those that strike Cuba, for similarities to Irma. There aren't many. Most originate in the southern Caribbean, or have more southerly origins in the east Atlantic. Probably the closest I could find was Ike, which would be really bad news for the area devastated by Harvey.
No one at NOAA is publicly guessing about Irma's track after the five-day models. Storms that follow her track are few and far between.
The only difference between Irma and Ike are the periods of original intensification. Ike developed more rapidly in the first three days. Otherwise, they are a match. Again, there are very few that follow this track.
Cont'd ... the reason these tracks are so rare is that a storm originating that far north off the coast of Africa will generally stay in the Atlantic, often off the coast of the US before spiraling northeast.
What happened with Ike and Irma was an area of shear that drove them back southwestward into warmer waters, where they reintensified before striking land, then intensifying again in the warm Gulf waters. They never were Caribbean storms.
>>9149050
But bear in mind that the future track of a hurricane is not much impacted by it's past track -- it doesn't carry much momentum forward. Fronts and the Jetstream and other steering forces are much more important.
>>9149064
Irma is closer to the path followed by Hurricane Donna from what I can tell, down to the exact date even.
