How i can learn a little about control theory before my semester starts? Should i grab a textbook and start working on examples or should i read it first? I almost never use textbooks when i am studying, i go over my notes and when i get stuck i ask a friend for help and it always worked.

If a star was instantly split in two down the middle and the two parts was moved a kilometer away from each other, what would happen?
>falls back together like nothing happens
>a lot of core mass escapes
>falls back together in a big fart
>or it goes nova instantly
One kilometer is nothing in star size but I thought the idea was interesting.

Can we use summation methods to get a value when limits converges to 0?
an example would be
[eqn] \prod_{p=0}^{\infty} e^{-p} = \sqrt[12]{e} [/eqn]
instead of just 0, this shows you how big the zero is.

I gotta a question fellas: If space and time are one thing, therefore moving in space I am also moving in time.If I was to stop all the energy in my body from moving in their own higgs boson field. Would I therefore be mass-less and not experience time like a photon?

What is your guys' opinion on the Microsoft Surface for note taking as a student? The one note software seems pretty neat but I'm not sure if electronic notes is a good idea.

I have one and use it alot (using it rn).
In my calc3 class, there were a couple of people that took theirs to take notes.... srs
I used it mostly for doing practice problems and stuff. Saves me mad paper yo.

Hey /sci, looking to get a better solder station. I got the Hakko 888d, but the din connector looks flimsy and does not connect properly. I'm returning it.
I'm looking at the "American Beauty Tools solder station".
Anyone have any experience with this brand? Is it good for soldering electronics? The temp rating is the same as the Hakko.
A google of the brand mostly brings up welding metals. There is a dearth of reviews for electronics tinkering and repair with their brand.

where did you manage to find this crap brand?

>>7798798
Is there any functional problem with your Hakko, or are you just sperging about how flimsy the plug looks? I have had my Hakko for years and it is still trucking along. The only thing better would be a nice inductive iron, but you are looking at an order of magnitude price difference for one that isn't total shit.
>>
>>7799103
The connector does not seat property and pops 1/4 to 1/2 halfway out. I'm returning it. Maybe it was a fluke? Do you have the Analog Hakko?
>>7798965
Google search for "rugged" solder station. I also saw some videos about a ham radio group making some yagis and they had the AB station.
the AB station is 146. USD.
the Hakko 888d is 96 USD and comes with a flush wire cutter.

Can one make their IQ a legitimate 160+ just through mind training and studying?

DXM (found in robitussin) in high doses has been shown to strengthen neural pathways in the brain ,acting as a nootropic, and perhaps is able to increase intelligence with repeated use. There is much information online alluding to this.
>>
>>7798777
I hope not.
One can improve their test results by training.
But that does not make them smarter.
There is another way.
In China, scientists have collected DNA samples from 2,000 of the world’s smartest people, and are sequencing their entire genomes in an attempt to identify the alleles that determine human intelligence. Apparently they’re not far from finding them, and when they do, embryo screening will allow parents to pick their brightest zygote and bump up every generation's intelligence by five to 15 IQ points.
I doubt they will be very successful at first but this is scary!
>>
>>7798777
The IQ test that I had took into consideration vocabulary and memory games. Most humans (if they really tried) could train themselves to excel at both of these things but not to a rating of 160+.

How do you know Time doesn't freeze occasionally?

The photons make up light which enable you to see things wouldn't reach your eyes until your eyes reached the photons.
That is, of course, implying that you were somehow not also stopped along with the rest of time, but I'm not sure what the implications for perception would be.

How do you git gud at chess?
I studied tactics, definitions and basic strategies but I always make weak openings or fuck them up eventually. When I manage to reach endgame by having roughly the same points of the CPU I just don't know what the fuck I should do

Hi /sci/.
Could you enlighten me on the best and most scientifically accurate books about health and diet?
I have been growing interested in taking care of myself and I want to know the best literature on the subject.

why?
Im a neurological novice. Im being put on medication for chronic anxiety. Whats the science behind changing brain chemistry with medication? Is it a "permanent" fix?

It alone is not permanent. It will stop the effects of your problem for a while and that is why you take it again. You have to keep taking it until you get over your problems but usually the reason you can even get over those problems is because the medication helped you be 'normal'.
>>
>>7796513
It is meant to help you in getting on the right track. Combining medication with psychotherapy yields best results. But you are supposed to quit your mediaction at some point.
>>
>>7796514
Yes this is why im doing it coinciding with therapy. Makes me feel better thanks.

how long does the brain take to repair itself after 5 years of heavy marijuana smoking?

The brain does not repair itself.
>>
The damage is permanent.
Actually I'm not really sure. From drugabuse.gov (probably biased)
Marijuana also affects brain development. When marijuana users begin using as teenagers, the drug may reduce thinking, memory, and learning functions and affect how the brain builds connections between the areas necessary for these functions.
Marijuana’s effects on these abilities may last a long time or even be permanent.
For example, a study showed that people who started smoking marijuana heavily in their teens and had an ongoing cannabis use disorder lost an average of eight IQ points between ages 13 and 38. The lost mental abilities did not fully return in those who quit marijuana as adults. Those who started smoking marijuana as adults did not show notable IQ declines (Meier, 2012).
