Hello /sci/ I recently quit smoking cigarettes by moving to a Vaporizer.

I tried to find some actual medical studies via google, but I guess I just don't know what to look for, because I can't find any articles that are just hard facts without shit-loads of bias.

Do any of you happen to have links to real medical study results or any insights into the effects of the standard Vaporizer chemicals(Vegetable Glycerin, Propylene glycol, Nicotine, and food-grade flavoring) on the lungs?

The reason you can't find anything is because it's barely been studied so far. Personally I wouldn't risk putting that shit in my body until there's solid science confirming it's harmless. (And also I don't want to be chemically dependent on an expensive habit that makes me look like a tool, but that's neither here nor there.)

Really, anything you inhale that isnt what your lungs were designed to process is going to have some adverse (not necessarily bad, but normally bad) effect.

this is actually very easy. you'll need an automotive battery (contains sulphuric acid), about two pounds of bitter almonds(preferably finely ground although coarse will work too), a cooking-pot and a stove. now just put the ground almonds in a cooking-pot, add about 350 ml of sulphuric acid and 150 ml of water(always add the acid first, then the water), and apply medium heat. stir vigorously for 5 minutes, remove the pot from the stove and let it cool. finally filter the mixture through a cheesecloth and you'll...

Yes.

Uni let's you know there are thousands of individuals around you who are smarter, more disciplines and better looking who still won't be successful, because there are tens of thousands even better than them in the state, hundreds of thousands better than them in the country, millions better than them in the world.

Not necessarily. Hell, most people I know fuck up at least one class as a freshman.

Personally I got a D in programming 101 and I felt like an idiot because, like you, I had always been good in high school

Unless you went to a private high-school you are pretty much expected to be top of your class academically unless you are an utter retard.

Everyone in my ChemE freshman class was either top of their class or came from a top 20 high-school and only 60% of those people graduated. That's graduated, the average time to graduate was 5 years.

O'reilley is being a bit mean here, trying to bait him to get mad with that artful rhetoric. Academics, if they're good, shouldn't be good at rhetoric. Actually they should actively suck at rhetoric, because their habitual use of facts should be so strongly ingrained it gets in the way.

As an unrelated note, have you ever noticed how human faces are really small compared to our head size? (look at the area enclosed by the eyebrows and chin as one object, and rest of the head as another object, you'll see)

I don't "call em out" because usually the person talking shit is unimportant while professionals know to not talk about shit they don't understand.

Usually people who know who I am will always ask my opinion instead of just talking about though, for example if someone in the room is talking shit, any person that knows me would turn to me asking "is she/he/that right" I will gently correct them.

Under any other circumstances I ignore them because whether I correct them or...

because sometimes you know you were wrong the moment you finished your sentence but between knowing for yourself and admitting to others there's a big gap and I respect that.

Why do people lie on the internet?

I'm looking at my grades and decide to read what other info is at my faculty's page in the university's web site.

After reading other interesting notes I find a short paragraph that details what my degree in Mathematics prepares you, professionally, for.

It first says that the degree focuses on teaching and pure and applied mathematics. I feel like that sums it up. I wouldn't call my degree pure or applied because it is a good mix of what you should know as a mathematician.

American degrees are worth more than whatever shit-stained paper you get after graduation. In college education you literally get what you pay for. You get it for free, it probably sucks. It costs you high, it will take you high.
