Hello, could any medfag please tell me if getting testosterone shots at age 23 can widen your jaw, lower your gonial angle (don't think so), etc, please thanks.
No.
You're already developed at 23.
Your bones won't "change" in any significant way.

I don't understand how people can have so much knowledge at their finger tips, and yet still be so dumb.

Miles are certainly flawed.
But using a measuring system based on the number of fingers on your hand is equally retarded.
When are you going to grow up and realize that 2's and 3's do a better job of defining reality than 5 ever will?
Do you die because your bodily functions cease?
Or do your bodily functions cease because you are dead?

You're your body, your body dies, you die.
Also, philosophy goes to >>/his/

A living creature is pronounced dead when it's main organs essential to surviving fail. You can't be dead if all your organs work.
What are 'you'?
A consciousness? Or a body?
If PopSci is based on real science, then why does /sci/ hate PopSci?
I don't hate pop-sci just like I don't hate pop music. It's just that the majority of it is bad.
>>8125448
>why does /sci/ hate PopSci?
>implying
Most of this board is either pop/sci/ or /b/ tier shower thoughts.
>>8125448
Popsci is good to get people an initial interest in science. It also spreads some science knowledge even if it isn't much. Popsci is bad because it gives people a sense of being more educated than they actually are(degrees do the same thing though). It also gives people a false sense that science works in grandiose movements. I think the pros definitely outweigh the cons though.
Which is superior? Morning people or night people?
I'm a night person myself, and it seems to me morning people are usually more driven and successful.
>>8125355
Yes.
>>8125355
Night person prolly means you are an introvert.
This world is built on who knows who.
It would be unsurprising that morning people seem more successful.
Do morning people actually exist? Does anyone actually LIKE waking up early? Or are some people just better at forcing themselves out of bed to get shit done?
It's possible to read enough STEM books to have an understanding of all major STEM degrees?
I'm not talking about becoming a researcher or any college professor.
I'm talking about having enough understanding to be able to mantain a conversation with any college profesor or PHD or look up lectures on youtube and understand them.
Those PHD students have spent years studying their field to get to where they are, and professors have spent even more. Exactly how long do you think it's going to take you to reach this level in EVERY field?
>>8125274
You could hold a conversation with them, but you sure as hell wouldn't be able to contribute much to the discussion.
>>8125274
No; you would be lucky to get through EE and ME/AE alone at a PhD level after 40 years of age
What if matter can not enter black holes but only orbit it due to gravitational spin.
Think of it like the international space station falling but never falls due to the earths spin thus orbit.
Black holes are gravity held together by gravity it does not use matter or destroy matter
It only makes and smashes elements by crushing presser within its accretion disk and after it dies its accretion disk forms new stars and planets due to the clumping effect of the spin but super massive black
>>8125246
:holes gravitational forces are too weak to keep stars and planets from forming within its disk
thus black holes are just gravitational holes in space time that only recycle matter
It does not destroy or touch matter its self.
hawking is a quack.
and black holes are fucking matter redistributors.
This seems autistic. Things do not orbit earth because of its spin. They orbit because of their horizontal velocity. The super massive black hole at the center of our galaxy for example does have complete solar systems orbiting it but nothing orbits at a super close distance like near the event horizon.
>>8125275
you can not create a orbit around nothing in space

How long can you safely stare at the sun?

I'm sure your retina is way stronger than your skin

Wrong
Retina is not exposed to the outside world ( except for minor amount of light) therefore it's much more delicate than skin
What are some of the rarest medical conditions?
Obviously, to keep the topic "sexy", conditions that really fuck people up are of interest. But above all we are interested in extremely rare-yet-identifiable conditions, which might not even negatively impact a patient's life to a significant degree.
The type of thing for which there are fewer than 1,000 patients in the world at any given time.
In these hyper-rare cases, how can science and/or medicine be legitimately performed? You're dealing with a small sample size, which makes things harder.
>>8124860
I don't remember the name of it, but there was some condition that caused your whole body to become bone over time.
>>8124868
bonitis?
>>8124868
Fibrodysplasia Ossificans Progressiva
In terms of rare conditions this has to be up there. Progeria, Epidermodysplasia Verruciformis, Cotards Delusion, Alstrom syndrome and Harlequin ichthyosis are to name just a few.
Joseph Merrick (OP pic) is a bit of a weird case since there is no consensus on what he suffered from, most likely Proteus syndrome and perhaps a form of neurofibromatosis: two very rare diseases in themselves, making him possibly the least lucky person in medical history.

Why does knowledge of the particle's path collapses the wave function?
Measuring it with a device changes their property. It doesn't know anything. The "observer" isn't a human, it's a device that interupts the process.
>>8124826
The measuring devices in a quantum eraser are identical.
I collapse your ass if you do not stop creating these threads.
How does this make any sense to anyone?
I'm trying to find an explanation of this, but every single one, the author of the explanation clearly has no idea what he is doing.
Not only that, but there's three different variants with no explicable difference in usage, yet every single one is different from each other.
[math]\vec{F} = q\vec{E} + q\vec{v} \times \vec{B}[/math]
is the law for a single point particle with charge q. If the electric field is taken to be zero (E = 0) then it becomes
[math]\vec{F} = q\vec{v} \times \vec{B}[/math]
Now consider a small infinitesimal part of a wire with many electrons flowing through it with no external electric field. The new form of the law becomes
[math]d\vec{F} = Id\vec{l} \times \vec{B}[/math]
You can now integrate it to get
[math]\vec{F} = I\vec{l} \times \vec{B}[/math]

>How does this make any sense to anyone?
It barely does. It is an attempt to simplify the complex relationship between moving charge (current), magnetic field and force. All three are vectors in 3D space with an orthogonal relationship. Hence the left-hand / right-hand motor /generator rules.
It's all about a magnet and conductor, move them and a current is produced, run a current thru the conductor and motion is produced.
then you get people like

> How does this make any sense
What is "this"?
The equation for (the magnetic component of) the Lorentz force (F=q(B×v)=B×I), or the mnemonic using fingers?
The Lorentz force doesn't "make sense". It's just how the universe happens to be. Physics isn't math; you can't derive it from first principles, you just have to make empirical observations and describe the results.
One of those results is that the force on a charged...

If f(x) is a polynomial, then its derivative f'(x) is the coefficient of t in the expansion of f(x+t):
