What's your favorite episode(s)?
I'd have to go with all the duct tape ones
>>7723960
One of the dumbest shows I've ever seen.
>>7723962
What's so wrong about it?
>>7723966
Non-rigorous and poorly controlled experiments. Their conclusions are presented with a moronic level of certainty when different parameters very easily could have yielded success. Their interpretation of legends and myths is also frequently left wanting.
The ice cannon comes to mind. Why would it have been a cylinder? Why would your nearly random choice of diameter and cannon ball size have been the only case? What was the salinity and mineral content of this frozen water, and what was the ambient temperature? How much powder was likely used? None of this was controlled for or even mentioned. They just did the "experiment", the goddamn thing WORKED, but it fell apart at later stages. Since it's TV they can't say "Well I'm kind of uncertain and further trials are needed... if we tweak these parameters then maybe x y z..." no, instead it's conclusively BBBBUUUUSSSSTTTTEEEEEDDDDD DUDDEE!!
You didn't bust shit. Every episode is largely the same because it's meant for entertainment. But people take it seriously. Fucking mythwhores.
Has population growth of this nature ever been witnessed in another species? What ended up happening?
This is what happens
>>7723897
Strange, but that won't happen for humans. Crashes only happen when the carrying capacity of the environment sharply drops.
>>7723897
I guess I should explain. Environments have a certain amount of carrying capacity which is determined by the features of that environment. How much food is available, how much water is available, the shelter it provides, etc. Any of those features can be considered limiting factors. If there is an abundance of shelter, that's not going to help a species if there is no food or water, for instance.
After a species exceeds the carrying capacity of it's environment, it will not completely drop off right away, but shortages will start to occur and massive die offs will ensue due to lack of resources. As a population exceeds the carrying capacity of it's environment, it can also damage that environment and lower it's carrying capacity. This is something we see in deer due to the lack of predators. The deer strip all the vegetation away, starve themselves to death, and invariably lower the amount of deer the land can sustain come spring. Damage to the carrying capacity of an environment can take years to recover. The picture shows the difference between a health understory and an overbrowsed understory. It's a little hard to see but there is a distinct line in the right image where deer can no longer reach up and nibble on the plants.
For humans, its somewhat different. We are a global species that is continuously raising, through science and technology, the carrying capacity of Earth, at least for humans. Once we exceed that carrying capacity, and can no longer increase it, that's when shit is going down. Just like the deer example above, we could completely ruin the planet for us (and everything else) and our population will drop like a rock due to famine, disease, and war over resources.
Can you guys help me out on my math problem? My friend says its six but I think it's one. Please help?
go back to /b/
>>7723815
both are correct.
For the record, it's 9 and only 9. Trying to explain that to /b/ is like pulling teeth though.
Hi /sci/
What is the evolutionary reason for moles and
are there any scientifically proven ways to remove them that do not involve going to a doctor or cutting?
>>7722898
Freeze them with liquid nitrogen.
Put duct tape on the mole for between V and VII days.
>>7722898
Do you have a mole Fetish Op? I will send you mole nudes if you ask.

Yes, we are all going to die some day.
>>7722704
Prove it.
Prove that we won't cure aging soon.
>>7722638
All these chemicals and drugs
Used and abused
Now you pay the price
How the fuck is this shit even possible /g/? VSEPR theory and hybridization all seem like bullshit to me. Pic related.

Easy peasy
electrons all have minus charges, so they hate each other and try to get as far away as possible from one another
We gotta account for this in our diagrams.
What's the matter, Chemistry 101 got your panties in a bunch?
>>7722554
yes.
Is PCR fun?
Today I got an offer for an undergrad research position (or the equivalent thereof in my country). It's a project with the goal of finding good primers for a certain type of HPV. I would be doing some desk work and lots of PCR for about eight weeks during the next summer.
Should I do it?
The alternative is looking for another reasearch project but most of them are just deskwork. It's also probably the only time in my life I would be working in a lab, so it'd be a new experience.
>>7722305
It's an interesting concept. but doing the reaction is not fun. you're going to be doing the exact same thing many many times.
>>7722305
That being said if you're in your undergrad, doing lab monkey work is really good for your career.
>>7722308
Exactly. As an undergrad, though, it might be fun at first, but it'll quickly become dull.
But I prefer doing it over desk work, for sure.
Tau or pi /sci/?
>>7721012
Pi 4 life
pi because it's more recognizable
>>7721012
Tau because it was invented by Terry Tao.

Calling all Calc experts
So, I started taking Calc1 in August and my final is this week. Never even heard of a derivative until Aug. I did well up until October, and then my grade started to plummet. After struggling for awhile I began to wonder if what we were doing was actually Calc1 material.
It started off as basic derivatives and integrals and whatnot. But sometime around Oct we started doing differential equations, integration by parts, cross sectional volume and volume by rotation, improper integration etc. Recently, right before exams we did infinite series stuff and discrete math.
Simply put, I want to know from some of you who have taken Calc if this is a normal pace for a Calc1 class. Keep in mind, its only been one semester, so most times we would only spend a day or two maximum on any subject. For example, we only spent one day on IBP before moving on to Euler's method.
Tl;dr Is integration by parts, volume by rotation, infinite series etc. normally part of Calc1, or is it usually covered in Calc 2,3,4?
>>7720583
Seems like Calc 2 to me. Your teacher may be trying to prepare you for the next level, but it still seems off.
integration by parts, volume by rotation, infinite series etc
is usually calc 2+ stuff. My Calc 1 class stopped at basic integrals
>>7720583
Shit man that's quite advanced for calc I. No sure about other places but in my uni we had:
-infinite sequences and serieses
-functions
-continuous functions
-derivatives
A shit ton of material on each subject, of course. Integrals were calc II, calc III was the fancy n-dimensional version of calc I. Diff eqs were a different course altogether.
Good luck m8
Girl in my class is bad at math and building circuit boards.

No. I got tired of women manipulating me years ago.

Would using AI for experimentation be considered ethical /sci/?
>>7719921
we're doing it
it's called 'software testing'
look it up b i a t c h
rekt
>>7719921
What kind of experimentation? The sort that would be unethical if performed on people?
If it was demonstrably sapient, then no.
>>7719933
>The sort that would be unethical if performed on people?
I'm thinking social sciences. Thousands of AIs in a double blind randomized controlled experiment. On one side, you have a control society, and on the other side you have an experimental society, where you change some policy like taxes or a regulation to look at its effects. Time would be accelerated and we will be able to see its effects in 5, 10, or 20 years.
Then they would be reset.

I try to take it easy on the snacking, though. It's easy to get fat.
Back when I took QM, I'd stay up all night and go through a box of donuts before 2 am. Gained 20 lbs that semester.
Why the hell are there so many global warming alarmists today? "Oh no, if we don't stop now, it's fucking game over. We'll never get back to where we were before!". Fuck all of you.
You believe in science just long enough to believe climate change, but don't believe that science can also fix this.
>We have too much carbon dioxide in the atmosphere, it's all over!
Except for the fact that we can remove carbon dioxide from the atmosphere easily. The only thing is, there needs to be more funding to make this more viable as today it's prohibitively expensive (so was solar panels back in 1980, but today you can get one installed at home)
>The sea water is rising! It'll swallow up entire countries!
Today, due to pollution we're running out of fresh water. One of the ideas is using sea water. In the labs, technology exists today that can filter out the salt without needing to boil the water. Again, it's expensive as of today, but soon it might not me. The amount of sea water we'd need to give to drought stricken California would be enough that it in and of itself would be able to stem the rising sea levels.
>Species are dying off! We'll never see them again!
Store a diverse set of DNA and cell structures. One day when we're able to create cells from scratch, we'll just make one in that shape and throw the DNA in it. Then, through the magic of science, we'll be able to repopulate once lost species when we've saved the world.
More & more people making careers in "green" bullshit who will profit from more government mandates.
Liberals becoming even more vocal on their stupid memes
>>7723278
Are you slow? The problem isn't that we don't know about these technologies, it's that most people don't care enough to fund them and actually make them viable on a large scale. That's why scientists are so vocal, because we need to develop these technologies but politicians want to keep most of our budget in fossil fuels and military.
>>7723369
They don't though.
Even at the high level paris talks, all they were talking about was sustaining the Earth rather than fixing it.
We have the tech, but no one cares to use it. They just put plugs in their ears and go "la la la la la the world's gonna explode la la la la la can't fix it"
