So I took a helicopter flight. We ascended pretty high and then just hanged around in the same space for a a while enjoying the view. I was looking down marveling at all the tiny houses and trees... and then it hit me! They all looked perfectly still! If Earth rotates at about 1000 miles per hour then how come all this time it was perfectly still while I was looking at it from the sky?

>If Earth rotates at about 1000 miles per hour then how come all this time it was perfectly still while I was looking at it from the sky?
very simple physics
you're so dense, when you ascended into the air it caused the ground to experience severe time dilation and thus stood still for you
>>7950950
The air you were in.... ready for this?
Moves... with.... the.... Earth
Well /sci/ I have to take my 2nd year oral astronomy PHD qualifier exam tomorrow.

Why do we know so little of dark energy?
Darks don't matter
It's too dark to see it.
Honestly, is there really a point to learning any kind of physics that isn't:
>Newtonian
>Optics
>Electricity
>Maybe nuclear shit
Virtually everything else is so theoretical and impractical that it will literally never ever fucking matter to anybody. Physicsfags love to make fun of philosophers but if your area of research is some retarded shit like string theory or multi-verse theory, you are no better than old Greek faggots laying around in their gardens all day asking hypothetical questions and giving ridiculously tedious answers to them.
>tl;dr
The only physics you need are Newtonian, optics, and electricity. And nuclear if you're interested in it. Literally everything else is a useless egotistical circlejerk
>>7950127
Every field starts out as an impractical mess. Do you think people realised what could be achieved with nuclear physics people started exploring it?
Without branching out into new areas we'd never make progress.
>>7950155
You suppose that all of these branches lead somewhere. Sooner or later you hit a dead end. What possible application could shit like n-verse or string theory have, practically? Almost none that I can think of. Not to mention it hasn't fucking gotten anywhere in 30 years.
At least the branches I named are "useful," even to the layman.
>>7950169
Then don't study them, nobody's forcing you. Now get off /sci/.

Just started my first C++ class(I study math) and I'm getting something weird. I built a code for a simple program for an exercise and the .exe file is 1900 kb, then extended it for the rest of the exercise and the new .exe file is 600 kb while the program does EXACTLY what the first one did, plus more. Why is this happening?
If you just started programming, don't ask questions that you don't want to know the answer to.
Now I'm not calling you stupid, but are you positive the first program was 1900kB and not 1900B?
The only other likely explanation would be that you were using some method from a library that had a lot of overhead, and that you might have removed something on the revision that you thought was minor but to the compiler was actually large.
The only way to know for sure would be for you to post both pieces of code here and I or someone else will look at it. For this reason I really wish we had [code] tags but alas they are only on /g/. You could ask them as well but they'll be dicks about it.

SURVEY:
How old are you?
How frequently do you masturbate and/ or have sex?
Are you experiencing any symptoms of hair loss?
this isn't a free survey buttkid. its a science board
28
I go through periods where I have hardly any sex drive and masturbate once every day or every other day for a few weeks then go through a period where I fap four hours sometimes 20x per day for a couple weeks then the cycle repeats
Yes, like NW5

I'll bite, assuming we were able to reach the hardware and software level to make a perfect copy of "you" in your life time, would you consider this being a continuation of you or is this just a being that behaves like you with the same memories?

Wow I can't even right now. Who are you to invalidate a child's lived experience? If a child knows what gender it is it is child abuse to not let it transition.

Ignore them, they are irrelevant.
"The American College of Pediatricians (ACPeds) is a socially conservative association of pediatricians and other healthcare professionals in the United States. The College was founded in 2002 by a group of pediatricians including Joseph Zanga, a past president of the American Academy of Pediatrics (AAP), as a protest against the AAP's support for adoption by gay couples.[1][2] The group's membership has been estimated at between 60 and 200 members."
"The organization's view on parenting is at odds with the position of the American Academy of Pediatrics, which holds that sexual orientation has no correlation with the ability to be a good parent and to raise healthy and well-adjusted children"
Read more on wikipedia about how they misuse other people's research, try to block sex ed, and support no sex till marriage 'education'.

Why the fuck are we still dicking around with electric rockets when nuclear rockets have high Isp and high thrust? Electric rockets are great for sending small probes and rovers to Mars but manned missions need nuclear rockets. SpaceX's ambitions are noble but even if the cost is reduced nobody wants to spend a whole year on a spaceship bathed in radiation. Liquid rockets and electric rockets are fully developed and will never be good enough for manned exploration of space, it is time we moved on. The only nuclear rocket development programme rapidly came close to outperforming chemical rockets in thrust to weight ratio, if it wasn't canned in the 70s it would have probably made chemical rockets obsolete by late 80s. Even in the 60s as a third stage on a Saturn V it would have been capable of lifting an unbelievable 170 tons to LEO
I don't exactly know the maths behind it, bur if something we're to go wrong either within our outwith out atmosphere and the craft were to explode, wouldn't that do a lot of fucking damage?
>>7951688
Damage to Earth? Not relevant in space. Damage to the craft? You can say the same thing about chemical rockets.
>>7951695
I believe that NASA and the United States aerospace industry hasn't been testing them much because they are messy. Furthermore any nuclear physics data needed should be collectible from inertial confinement fusion experiments.
They definitely have it on their list of preferred options for pushing back against the rocket equation however.

Anybody here good at graduate/4th year linear algebra? We're currently on norms and inner products and the shit is bonkers hard. Pic related is the book we're using. If I give you a couple of exercises (or personal questions, that I just don't know), could you give me some help?
