Any mathfags on here that use to be bad at math? I use to hate it as a kid. I was barely able to learn my times tables back in elementary school. In freshmen year of high school I failed algebra 1 and had to retake it. However, by junior year I realized all I needed was a lot of practice. I significantly improved and even started studying some math outside of school. I now love to do and discuss math. Anyone have a similar story/experiences?

i was sort of good at maths but i hated it. then once i got to calculus and differentiation and stuff i though 'wow look at all the pretty symbols, maybe people will think i am smart if i can use these' so i studied, and it turned out i enjoy maths

Real potential requires a person to be talented at math from birth. That's what I believe, but perhaps it's possible to become pretty good even if you were once bad.

I'll start
so I'm supposed to find the area between two functions
y1=ln2x, y2=lnx, and x=2
ln2x is the upper function and lnx the under? function, I did it, and I get
2ln2-1/2, but the book's result is 2ln2 only
I ran it through wolfram alpha and I get 2ln2-1/2
what gives? did I formulate the problem wrong?
integral of y1 - integral of y2 = area between curves

ln(2x)-ln(x) = ln2
the integral from 0 to 2 of ln 2 is 2ln2

>>8716769
aaaaaaaaaha, for some reason I was considering the area only above the x-axis
thanks a lot, anon

Okay cool.
I'm having trouble getting the right answer for this. I'm taking cosine law, deriving it and putting it into the work energy equation but my answer is not what it should be. Am I doing it the right way.

Semi-weekly reminder that exposure to ELF to upper microwave band radiation causes brain damage, cancer, reproductive problems, broader psychiatric issues (depression, anxiety, insomnia, etc), and alters human behavior.
It does this by acting on the voltage sensing subunit of voltage gated calcium channels (predominantly L-type), leading to chronically elevated intracellular calcium. Aberrant Ca2+ flux affects Ca2+ regulated cellular machinery and ultimately ends at increased NO production. This overwhelms normal physiologic processing pathways, and begins to react with superoxide to form peroxynitrite.
Observed effects of lower frequency pulsed and static fields on organisms, both at thermal and non-thermal levels, dates back to the late 60's and was understood to be biologically active even at that point. Epidemiological data has been extremely consistent, and the low level mechanistic approach is beginning to fill in the underpinnings of these observations.
Belief does not make actuality. It's time we decided as a species whether we're ready to face reality, or if we will choose to fizzle out living a pitiful fantasy. The rate of discernible autism spectrum abnormalities are now, at a low estimate, 1 in 45 children. We know of a genetic polymorphism (Timothy syndrome) that causes overactive VGCCs, and correlates universally with autism. We know calcium signalling is integral to synaptogenesis and dendrite formation and maintenance. Might be something to think about.

It is time. Li-Fi can replace wi-fi, something can possibly be done for cell phones and all the other little toys too. I'm tired of dealing with this asinine nonsense. The effect of their use goes completely against people's purported value system. It's intellectual dishonesty and addict behavior.

Look around you. Cars that use radar fill the roads. A cell phone in the pocket of nearly every individual. Wi-Fi in every building and every workplace. Even if I ignore having to watch decent people embrace their own decay, and that they're damaging their children, it's just becoming an unavoidable nuisance to me personally.
The answer is multifaceted, and incredibly obvious. Think big, and think small.

Should we introduce legislation forbidding websites from posting anti-scientific nonsense? Taking websites such as Natural News or How Stuff Works into consideration, they outright lie, misrepresent citations, fear-monger and so in an attempt to sell bullshit products/support their own agendas.
This has nothing to do with politics, but rather they actively make the population dumber and oppositional to highly beneficial technology to the point where commercial viability of said technology is impossible. Take Golden Rice for instance, anybody who isn't a complete fucking retard understands how GMOs work; there's no magic chemical voodoo and nothing at all in the process to suggest they're unhealthy or dangerous (countless reputable studies claim the opposite). Golden Rice in itself is a very promising endeavor in ending world hunger, however people en masse whose knowledge of GMOs amounts to "IT'S NOT NATURAL/HAS CHEMICALS/I DON'T UNDERSTAND SO IT'S BAD" actively campaign to shut it down as a result of absurd amounts of misinformation spread by idiots and organic food retailers. These same people are extremely vocal and completely unwilling to even consider or address factual arguments, instead just brainwashing other idiots to join them.
>but muh free speech
That's not being persecuted for your political beliefs, it doesn't protect you from claiming any sort of bullshit you want is fact.

>This has nothing to do with politics
that's where you're wrong.
you're also wrong about golden rice; it's not the most efficient way to end world hunger. food prices are dominated by transport and storage, not growing costs. and if you want to get micronutrients to people, supplementation is more efficient than engineering it into the crop genome itself. transgenic GMOs are a different reference class than selective breeding and they have a wholly different risk profile. not saying they're bad, just that "they're bad because they're not natural" is a strawman.

Pretty sure severe fines would get them to stop, the government can just walk in and shut the site down themselves if they wanted to, anyway. You'd really only need to go after the bigger ones both because they're the ones people read and to set a precedent.

I didn't say golden rice was perfect, I said it was promising and the opposition is entirely unscientific
>just that "they're bad because they're not natural" is a strawman.
Have you spoken to the average person on this subject, I promise you it isn't a strawman

Yes, there is a chance of that happening. The risk is rather small.
>>
>>8731658
There's a chance of that happening, sure, but it's minuscule. Which is why they do an x-ray before an MRI or CAT scan.
>>
x-ray can damage DNA and cause cancer, however for normal x-rays the chances are tiny.
unless they use some incredibly intense and uncommon techniques, you need to take a lot of pictures to get over the 20mSv per year limit for radiation workers.

2nd year geophysicist in the UK here worried about my future...any Earth /sci/entists care to share a bit of advice, especially fellow Britains (all are welcome though).
I'll greentext my situation to make it easier:
> Did a shitty media studies degree and spent 3 years on jobseekers between shitty zero hour contract jobs because I couldn't get my shit together
> Mum died when I was young and invested, what was now £30k in to a savings account
> I vowed to turn a profit on that money, so I opted for a career change and decided to work in either the gas or oil industry...hence I am studying a relevant subject for the field. In short, my heart is set on these industries.
> I understand that this work will mean travelling
> Met an amazing girl towards the end of my second year, we've talked about our futures together
I am worried about when I do get a job, it will be tough on her, and how will I manage as a father with a job that involves being away for long periods of time. It worries me to think that I may comprise the upbringing of my future children by not being there for them. She says she is OK with travelling for a while, but I still feel guilty
I went in to this degree to try and get a well paid job. I kinda don't want to settle for work in an environmental geophysics company ; the closest environmental science company is RSK, and by all accounts they aren't great to work for and the wages are pretty low for what you could get. I mean if I was to only get a job paying low £20sk, I honestly would never have bothered going to uni in the first place.
Am I a naive fool? Am I worrying about nothing or do I have cause for concern? How will I manage family and relationships whilst working in oil or mining? I am not surprised if I've said something completely idiotic. If I have, I don't mind criticism, but could it at least be constructive
Sorry if I have waffled on, I am feeling a bit sad at the uncertainty ahead.

>Markets change, you should never worry about the here and now but what is to come. As a geophysicist there is little to actually contribute if you arent inceptionally intelligent.

Cus geology is sciences, social studies (gender studies)

I like studying science though. Geoscience fascinates me, and I look forward to the career in industry, but it makes me sad to think of the potential that I may ruin my relationships with people I care about

The only answer that is ever given is to discredit IQ test methods. The common reason given is that most IQ tests (created by people in the western world) suffer from a cultural Bias that "cannot be eliminated". Meaning that subsaharan Africans only score poorly on IQ tests because they weren't raised to understand them.

Why are low IQ especially liberal people so obsessed with solar?
Do they get fucking obsessed with it and crying about how we need more when they don't understand how it works?
Like the storage problem, the fact costs are still not good, and that it would be a tragic economic mistake to force a switch before it's economical?
I never once see any solar libtards obsessed with green energy talk about the storage problems or reliability problems.

Based on the multiverse theory, all previously known and yet to be discovered anime universes exist and each has their own infinite versions
That being said, either once gumans progress to the techology capable of traversing the multiverse and find the. or when they come to visit us will fulfill mankind's true and only destiny.

Infinite possibilities means every possible combination of atoms would exist in another universe. Therefore, most of the anime universes would be filled with deen abominations or worse, and it would be almost impossible to find a good aniverse.

>>8730976
There are infinite amounts of "good" anime universes. When the technology is available we could have dedicated teams sift through them all to find ones that are acceptable for human interaction

There could be other particles besides atoms and traditional subatomic particles which make up matter in other universes as well

No. Do what you honestly find interesting in your subject and be creative with it. You'll create good science, and maybe if your lucky, your science might get a Nobel prize. Maybe the science is revolutionary. Then and only then will you become elite.
