Yup, just go to the best public university near you and git gud.

Many great mathematicians went to the best public unis as well, so nothing wrong with doing your undergrad in a public one.

Now on PhDs are a different story though.

Yeah, well...I'm sorry to break the bad news to ya pal, but basically your new BS Chem degree is pretty damn near worthless. Oh I'm sure you'll eventually put it to good use, but it's probably gonna take some
more effort on your part.
So, wassup? Why ain't da Chemists in da house? The reasons, (as I see 'em) are myriad. Read on:

The value of Chem degrees (at all levels) has become so diluted in recent years that in most cases they're not worth the trouble. With your BS, if you go out and get a lab job, you will probably go nowhere in your career. You'll be a permanent technician, with low pay and little hope for career advancement. If you go into an industry like pharmaceuticals, they'll probably start you out as a 'Technician', making about $28k/yr. QA/QC is particularly bad choice, since the science is very well established and the work is repetitive/boring. Your brain will wither and die. Whatever the position, after awhile, if you're good, you'll get promoted to an 'Associate' scientist position, where you'll rot for as long as you remain in the lab. You'll top out after a few (10+) years at about $ 60-65k/yr. (which is about where you'd start with many MS Engineering degrees), and you'll still have little say about the direction of your project, dept., or company as a whole. By that time, you'll either have to rot until retirement, or bail out completely and switch careers - a move which may necessitate additional education and entail financial hardship. If you've got 2.2.kids and a big suburban mortgage payment by this time, completely switching gears might be real tough. Plus, if you don't do it before you're 40, you'll face rampant age discrimination - you may find yourself about as employable as a plate of cold tripe.

The situation will be worse if you go into environmental labs, etc. They'll pay you hourly (you'll probably be punching a time clock. Humiliating after spending 4-5 years seeking professional respect) @ at rate of about $12/hr. or so....Pathetic. You'll be running tests on contaminated soil and water samples: PCB's, oils, heavy metals, chlorinated pesticides, coliform, etc...the established EPA methods. Pretty much cookbook after you learn how to push the buttons on the AA or GC/MS. Borrrrrring as can be. Again, you'll rot unless you get into management; you'll get better pay and no time clock, but your brain will most likely still atrophy. Take my advice: AVOID ENVIRONMENTAL TESTING LABS AT ALL COSTS!!! They Suck big time. I know this from experience, and I've had this opinion corroborated by the expressed opinions of many others.

And don't even be thinkin' about graduate school in Chemistry. If you go for an MS, you'll be lumped together with the BS chemists by the PhD's and hiring people-there is little distinction between the degrees in their minds. Oh sure, your starting salary will be a little higher, but you'll still hit the same vocational glass ceiling, especially in big pharma. The MS Chem is widely considered to be a 'consolation prize' for someone who couldn't hack grad school. Of course, this is not necessarily the case, but that's the prejudice out there. Anyway, just look at the (few) job listings: most companies are looking for BS/MS 'Technicians' and 'Associate Scientists'. When was the last time you heard an Engineer (BS or higher) referred to as a technician or 'Associate Engineer'? There is little respect for chemists out there, and unless you're a brain dead idiot that likes the predictability of being a glorified peon, avoid this pitfall.

>>8803980
If you go for a PhD., the road is fraught with land mines that no one will tell you about. Don't expect objective advice from ANY academic, as in many cases there is a serious conflict of interest between what is best for them vs. what is best for you. The undergraduate professors will love to see you go on to grad school, because then they can brag about all the 'successful' undergrads they've sent to grad school. Their big Ego's, as well as their promotions and dept. funding depend largely on their student head count. If they can boast about placing their graduates in jobs (any jobs) or grad schools, it makes them look good to the administratium, as well as prospective suckers...err.. I mean new students.
>>
>>8803985
As for the graduate schools, they'll beg anyone with a 3.0 or better G.P.A to come (of course, some are more selective, but this is about the GPA where they start). You see, they have a dirty little secret that they don't like to share with naïve prospective grad students: They DESPERATELY need English-speaking TA's and RA's (teaching and research assistants). For safety's sake and other reasons, teaching Chemistry is very labor intensive. For one, most of the cattle-herding big schools have really big undergraduate classes: 300-600 students is commonplace in freshman and sophomore courses. Moreover, almost all technical disciplines require their students to take at least a year's worth of chemistry-it really is the 'central' science. Consequently, there are a lot of big classes, and those students need individual attention that most professors cannot give. Therefore, they have TA's to hold smaller discussion sections, office hours, and proctored exam sessions. In the labs, unlike many other fields, safety is a primary concern (mostly due to fear of being sued by the starving armies of amoral, low-life lawyers out there.. oops, I digress.). Anyway, they need warm-bodied Anglophones to be TA's for the undergrads in the laboratory classes. These babysitters don't necessarily have to be brilliant or anything, just knowledgeable and attentive enough to keep the little meal tickets from blowing themselves up, etc. Just rubber stamp their plagiarized lab reports and send 'em on their way. Keep their tuition paying Rah!-Rah! parents happy by boosting the perceived value of the school with a kick-ass football team (with a coach that makes 2-3X what the highest paid faculty member makes). Etc. etc.

My answer has to be Joshua King. Read this following quote:

"Joshua King came to Cambridge from Hawkshead Grammar School. It was soon evident that the school had produced someone of importance. He became Senior Wrangler, and his reputation in Cambridge was immense. It was believed that nothing less than a second Newton had appeared. They expected his work as a mathematician to make an epoch in the science. At an early age he became president of Queens’; later, he was Lucasian Professor. He published nothing; in fact, he did no mathematical work. But as long as he kept his health, he was an active and prominent figure in Cambridge, and he maintained his enormous reputation. When he died, it was felt that the memory of such an extraordinary man should not be permitted to die out, and his papers should be published. So his papers were examined, and nothing whatever worth publishing was found."

He fucking trolled all of academia, he had the talent, but decided he wanted to chill. After universities have tricked so many students with the STEM meme, it's good to see one student strike back, even if it was a few hundred years ago.

I accidentally used active yeast instead of nutritional yeast on my popcorn. The stomach will kill it right? Or can it colonize the intestine, cause fungemia etc? S. cerevisiae boulardii is used as a probiotic so certainly some of it has to survive?

Why is Pi infinite, sci? Why can't you calculate the area of a circle using a normal number?
49 posts and 4 images submitted.
>>
>>8803608
We can prove that pi is irrational.
I don't think there's a proof that the ratio of circumference to diameter HAS to be irrational, if that makes sense. It just turns out that is is.

Here's a list of proofs that pi is irrational:
https://en.wikipedia.org/wiki/Proof_that_%CF%80_is_irrational
>>
>>8803658
That's interesting, thank you. Sadly, I am no mathematician.

My idea was that Pi has to be infinite, because you can only calculate something that has corners. So if you want to calculate the area of a circle, you think of the circle as a shape with infinitely small corners. And to do that, you need an infinite number, that happens to be Pi. Would that be somewhat correct?
>>
>>8803671
Many cornered shapes need infinite numbers.
Like a right triangle with legs length 1.

use black holes to distort space-time and then travel in it with a spaceship and see where it goes.
Perhaps travel into parallel universe where it could be for example today in earths orbit therefore time travel.

You can find people like that on /pol/

You can even go there and talk to them about it!

Help me out /sci/, I need ideas for a non wallet breaking way to kill pest birds, mostly grackles, at least 5-10 yards as a minimum, longer being better.

But for constants, without a projectile or anything that could harm random people near you, such as laser beams on shielded eyes.

As for what defines a projectile by dictionary,
>projectile: a missile designed to be fired from a rocket or gun.
>missile: an object that is forcibly propelled at a target, either by hand or from a mechanical weapon.
>object: a material thing that can be seen and touched.


The only thing I can think of at this point that fits the bill is a vortex gun, but I'm really looking for suggestions.

I can build anything non-too far out there.

A shotgun is cheap and so is birdshot. But you can't use projectiles, too bad.

>>object: a material thing that can be seen and touched.

I was going to suggest a net or poisoning their food, but this is material I guess. What you can do then is dismantle several microwave ovens, place the magnetrons next to where they eat, and hope it does some damage.
>>
Can you not just make sure nobody happens to be standing behind the birds at the time? That seems like a pretty straightforward solution.

I should have mentioned this is at my work, and basically we are going down the list of shit upper (as in not at the store) management has told us no for.

Basically the problem is they fly around our lumber yard and shit on all the wood staining it, then fly into the warehouse area where we sit and shit all over our space.
They just cover everything in shit and ruin product and our days, but despite the ruining product upper management doesn't like the idea of employees walking around with weapons.


Only one of the managers has permission to use a BB gun to kill them from corporate, but hes always really busy.

BB gun is what we used to use, that was no no first time they saw that.
Then a bow
Then a slingshot
Then a old sling and rock
Then they just said outright nothing that shoots projectiles.

As to the magnetrons, I thought about that honestly, taking a bunch and trying to waveguide them into a beam to at least fry the little shits from like 5 yards maybe, but I would have to do a lot of reading up to find myself competent enough to pull that off.

At this point the only thing I can come up with is a potato gun like vortex gun to hit the little shits with a wall of highspeed air to hopefully break their wings so I can go smash them.
The reason I need some reach is because they usually sit up in the rafters which is a good 25-30 feet up.
I figured /sci/ would enjoy these retarded constrains as a stupidly impractical solution is the only allowable solution sadly.

What is the consensus of intermittent fasting(18/6, or more) and its effect on brain? Is it good, bad or nothing?
10 posts and 1 images submitted.
>>
>>8800693
Loosing weight and fasting can cause production of ghrelin to increase. This will make you ravenous, usually irritable, but also more focused on tasks and better able to learn and use what you've learned. It also aids in building muscle. This should not be confused with hypoglycemia/hyperglycemia which will fuck up what you are wanting to do. If you need to take a test or go to a job interview, try to get that ghrelin flowing.

It also helps your body balance multiple sources of energy. Thus, your brain will become more energy resilient.
>>
>>8800765
While I like what you wrote can you back it up and did you recommend it as a daily thing? I've heard people saying intermittent fasting deprives the brain from is glycogen and thus bad for us.
>>
>>8800693
University of Southern California did a bunch of research on this you can find if interested.

The fasting needed to be a period of 5 days though, done every month (or every X months if already thin) in order to gain the benefits of cell regeneration. They also discovered you can simulate a fast, by eating under X calories per day. The people involved made a company out of it called prolon https://prolonfmd.com/science-research/ but if you check the papers you'll find exactly what calories/what to eat instead of spending money on their 'mimicking fasting kit'.

The whole daily fasting thing by skipping breakfast/lunch is a meme spread by that lean gains guy, Joe Rogan podcast pseudoscience and plebbit. Meme as in no studies done worth review
