Anyone else here ever feel that everyone else in STEM is a drone and you are the only free-thinker in your class? Be honest. It's fedora but I can't be the only person who has ever felt like this.

yeah. you know whats funny ? Everyone else in STEMs think the exact way like you think. But you're all dumb enough to think you're special which makes everyone a drone.
>>
Yeah I know, what you're talking about. Granted, I'm still a first year, so maybe all the normies haven't been sorted out just yet, but still.
It is as if everyone just follows, what we are supposed to do and yes some of the others are way better at what we're currently doing than me, but it seems like as if they are not impressed by- and curious about what anyone at the institute does. I have been around talking to professors and they have showed me their research and I enjoy it and I understand most of it, but all the others are just like "nah, that'll still be there, when I get my cand.scient - I'll see it then" - that is, if they're interested at all.

Gardasil 9 was approved just approved for males through age 26 a few days ago (it was approved for females and younger males last year). I'm 24, male, and a virgin. Should I get it?

The last thing I want is oral cancer, or to be thinking that I might get oral cancer in the future while I'm eating out a girl. It would also suck to think that I might have given my partner cervical cancer.

That said:

>it's something injected into my body, which despite allegedly being incredibly safe, is still scary
>it's expensive as fuck at around $200 per dose, and you need 3
>it seems to be hard to get in my neck of the woods at least (which scares me, since fewer people have gotten the 9 version vs. the original version which has been around since 2006 but only covers 4 strains, HPV16 probably being the most important)
>I found a study which suggested that getting Gardasil (they didn't test the 9 version) might increase your chances of getting strains not covered by the vaccine: http://www.abstractsonline.com/plan/ViewAbstract.aspx?mID=3682&sKey=7f019f73-accb-484e-becc-5ecc405f8ec5&cKey=e2313b32-d6ac-4443-ab2d-49c368ea3b89
>in the FDA briefing for Gardasil in 2006, a study among a subgroup showed that Gardasil might have increased their cancer risk by 44.6%, although it was a very small subgroup, and there were some differences between them (search for 44.6 in this PDF: http://www.fda.gov/ohrms/dockets/ac/06/briefing/2006-4222B3.pdf)
>penile cancer caused by HPV is incredibly rare at around 700 cases per year, and oral cancer caused by HPV is also rare, but less so, at around 8K cases per year (this number is rising however)

I keep going back and forth between getting it for peace of mind, and not wanting to get it because of those things listed above, plus any potential unintended consequences (such as other HPV types becoming more dominant which are more likely to cause cancer or cause cancer at the same rate but the cancer ends up being worse).

Thoughts?

What is it and what does it do?

>>7735965
It's a vaccine that has about a 98% effective rate (in females) against preventing HPV infection of 90% of HPV strains that cause cervical cancer and genital warts.

One of the strains in both regular Gardasil and the new Gardasil 9 that the vaccine protects against is HPV16, which is believed to be responsible for most instances of HPV-induced oropharyngeal cancer, which you can get from eating pussy, like Michael Douglas did.

Is khan academy a good place to start learning chemistry up the first year undergrad? I want to major in Chemistry, but I want to make sure I cover all highschool material before I go in the fall. I dropped out of my last program because of how much I hated it.

Why do you do this to yourself. You have enough time to find another potential interest and yet you decide to go back to the shittiest science.

Literally memorize reactions to pass. No critical thinking required.

Tell me that at least you are going into chemical engineering and not pure chemistry because at least in ChemE its less about memorizing reactions and more about learning practical skills to be able to carry out reactions in the real world.

Why are Americans so butthurt at Europe lately? Is it because they're jelly that all the frontier science (particle physics, fusion, astrophysics, ...) is now being done here? Or more specifically because they haven't been able to catch up in these fields? Or because of the higher educational standards being enforcer here (generally speaking)? At any rate, science is one of the most globalised fields in the world. If you’re unhappy with your own country for the aforementioned reasons, just move instead of being salty little pricks. Jesus.

Collaboration, people.

Math major here looking to learn some physics on the side. So far all of the physics textbooks I've read have all felt a bit too... "hand-wavy". It's a bit difficult to explain, but they don't feel formal enough. It just feels like a bunch of disjointed information and ways to model it.

So I'm looking for a textbook that does this physics thing a bit more rigorously. Definitions, with motivation, and then builds upon that every step of the way. Is there a name for this approach by the way? Is it a stupid way to go about things, or no?

It's your brain telling you you have no innate talent and you're too stupid to understand physics. Stick to math if you constantly need everything spelled out to you like a retard.
>>
>>7735188
I have no trouble understanding it. I simply wish it was more rigorous. We should be able to derive more complex physical truths from basic ideas.

>>7735192
well, you could 'derive' all the classical mechanics from the newton's laws, good luck

Hi /sci/
I'm dating a girl, and about a week ago I did the non-newton fluid experiment with potato starch and water, you know, the one that if you punch it feels like a wall but if you slowly put your finger in feels like liquid water. She liked it a lot and asked me to show her more "cool science stuff" like that (she has very little background in that).
Now, the thing is, I've been doing a lot of "homescience" stuff in the past with my geek friends, but since I am getting a PhD in mathematics soon I kind of left all that stuff behind (I was pretty surprised I remembered the right quantity of water to make that fluid)... and, even doing the stuff I recall, I always did experiments that weren't that beautiful (like measure some constant or or see for yourself that elastic force is linear - the falling slinky thing, anyone? ) in the eyes of a "commoner". I really can't remember other "cool" things.

So, can you help me with that /sci/? It doesn't have to be basic at all, just don't make it too dangerous!

3) care to elaborate? If you mean that "it burns" and stuff... how is that exciting? Might as well light up some fireworks.

Draw out cycloids or cardioids or something using a pencil, some string, and different circular objects.

Please tell me there is a very good chance that we may discover life on the dwarf-planet of Pluto?

This world seems too alive for there not to be any such life whatsoever. I do not mean extraterrestrials, of course, I mean some advanced form of extremophiles and microrbs.

Ever since NASA made the announcement that this little dwarf has it's own mountain ranges, lakes, ice caps, craters, it's own weather system, and blue skies, I've been intrigued on rather or not life could exist on it.

It seems like all of the conditions could be there.

Any Neuroscience Majors here /sci/? Undergraduate or Graduate people welcome.

What research are you working on right now? I'm currently doing some Behavioral Research concerning Vagus Nerve Stimulation combined with auditory discrimination tests. Nothing wet, but dealing with rats for 11 hours a week is surprisingly relaxing.

BCI in humans to facilitate human-machine mediated communication (fmri)

nothing novel yet, we're working on making it work, optimizing the procedure. We're running participants next month so we still have a bit to go before any results

If you have any reading/lecture recommendations on understanding neural networks and relevant mathematics please do share, my background is from a completely different side and we practically didnt cover these topics at all. Its quite impressive how interdisciplinary work is in neuroscience

I understand in detail how evolution works in all forms, but I'm at an impasse at how the FIRST cell structure was formed.

The ability to continue on is what drives the evolution argument, but the atomic ingredients in cells cant follow that same principle so how did the FIRST stage of evolution begin.

Its annoying me halp
