What's the best psychological method to deal with fear of abandonment? I mean, I suppose it's something you develop when your mother transmits you lots of insecurity during your first years of life, and that will transform into general anxiety disorder, low self-esteem, depression and other illnesses.
The thing is, once you know what's at the core of the problem, how do you recover? Is there any specific method?
>>8125840
I'd wager that the only way is to slowly force yourself into the situations where your fear of abandonment appears and then live through them rather than pulling back
only by continuously exposing yourself to these situations and finding that you do not get abandoned you'll change your innate emotional response and way of thinking
at least, that's one of the basic principles of cognitive behavioural therapy, that you have false, exaggerated or unreal cognitions, which we challenge/ease into

one shouldn't exaggerate the importance of early attachment/childhood experiences too much - while attachment theory is pretty valid and all, the psychodynamic freudian stuff isn't too spot on
obviously the importance of early experience differs between theory, but cognitive behavioural therapy for example doesn't put that much value in the supposed experience that birthed a problem

Omega Hall Trolley Problem
Before the Problem begins, Omega uses godlike predictive power to find out whether you are a Switcher or a Stayer.
Omega presents you with three doors.
Two of the doors, if picked, will cause a trolley is to run over five people.
Behind the third door, there is another trolley.
-If Omega predicted you are a Switcher, it will run over ten people.
-If Omega predicted you are a Stayer, it will run over one person.
Having picked a door, Omega now reveals that one of the doors you didn't pick would have been a Five-Person door.
Should you switch or stay?

Before the Problem begins, Omega uses godlike predictive power to find out whether you are a Switcher or a Stayer. But you cannot falsify until after the test.
Omega presents you with three doors.
Two of the doors, if picked, will cause a trolley is to run over five people.
Behind the third door, there is another trolley.
-If Omega predicted you are a Switcher, it will run over ten people.
-If Omega predicted you are a Stayer, it will run over one person.
Having picked a door, Omega now reveals that one of the doors you didn't pick would have been a Five-Person door.
However, Omega places everyone on a trolley that is moving much slower than the trolley. By the time your trolley reaches where the trolley carrying the people once was, the people's trolley would have moved ahead a little. And by the time your trolley covers this distance, the other trolley has moved ahead some more.
But as the trolley moves a wheel rusts, so Omega replaces a wheel with an identical one. Then he replaces an ungreased axle with another identical. It does this until the entire trolley is replaced.
Should you switch or stay?
Hey /sci/. I was wondering if there was an absolute most efficient way to multiply large numbers together, by hand.
Without resulting to a calculator, how can I take
a * b
and figure out which c fits to
a * b = c.
What would be the absolute best method or approach to calculate what c is equal to, if you had to do it all by hand.
>>8125757
logs and log tables?
>>8125757
> was wondering if there was an absolute most efficient way to multiply large numbers together
New algorithms (essentially variants of Furer's algorithm) continue to reduce the asymptotic complexity, but Schönhage–Strassen is the fastest algorithm that's actually used in practice (more advanced algorithms are only faster for numbers with billions of digits).
> by hand.
This is a meaningless qualification. For a non-trivial number of digits, the fastest "by hand" algorithm is the same as the fastest computer algorithm, as asymptotic time complexity always beats micro-optimisations eventually.
>>8125761
OP said "large" numbers, which rules out the use of tables (the size of a table is inherently exponential in the number of digits).
Using tables at the base level only gets you a constant factor, it doesn't change the algorithm or the asymptotic complexity.

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.

>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.

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.

I don't remember the name of it, but there was some condition that caused your whole body to become bone over time.

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.

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]
This lets you talk about wires instead of point particles.
You should be able to convince yourself that both ways of writing it are equivalent. The charge (in Coulombs) times velocity (in meters/second) is equal to the current (in Coulombs/second) times length (in meters).
>>8124736
>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
>>8124866
who give near non-sense statements like
>a wire with many electrons flowing through it with no external electric field
A current with no accompanying electric field? I hate to break it to you but this rarely happens in the real world. Electric and magnetic fields are inseparable from current flow in the real world. These "special cases" are to simplify a very, very complex equation (maxwell's) into an engineering ready equation that can be used to approximate special real world conditions.
The real fun comes when you realize that a real world motor also acts as a generator, generating in the wrong direction and a real world generator also has motor action with the torque acting as drag along with the mechanical losses. The true engineering is in reducing these factors.
It also gets interesting when you realize that magnetic forces have complex force vectors that have torque component (cw / ccw and magnitude) as well as the ordinary linear component of direction and magnitude.
This results in magnetic fields only being able to transfer physical force along two of the three axis.
>>8124736
> 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 particle moving in a magnetic field is equal to the charge (a scalar) multiplied by the cross product (a vector) of the magnetic field and the velocity.
