My bad, sin(30) is 1/2. So final solution is 3/2

You just calculate their value and add that.
tan(pi/4) = tan(45) = 1
sin(30) = sin(pi/6) = 1/2

final solution is 1 + 1/2 = 3/2

Okay so you take the opposite of the value given, I mean if it gives radians you turn it into degrees and vice versa, and then you calculate it and add them?
This is a big help by the way.

Well it's not necessary to do radian to degree or degree to radian conversions, I just wrote them out so you can see that they have the same value. If you do a lot of math you just know those values. Try to draw a circle and see where those values would be by definitions of sin and tan. I always do that in my head if I can't remember exact values.

Anyone else an advocate for breeding control? like you must pass a child care test before you can have a kid or it is seized by the state and re issued to another family. Day-care providers have to go through college to tend to children so why don't irresponsible parents have to do so? also i believe that humanity is overpopulating the world, so one kid per family, with severe punishments per extra kid. i am willing to hear any rational minded people willing to discuss this with me. not argue, discuss politely like the gentlemen that we are.

Oh my god that wrong on so many levels. But let's look through your points.

-Must pass a child care test or child is seized by the state.
You are taking a "guilty until proven innocent" stance on parenting which is pretty dumb in itself, however the bigger problem lies in the psychological damage you're going to afflict these children. You are literally making generations of adopted children and everyone in the world knows that is a bad thing.

Plus you say you will just "issue to another family" but you are simply assuming that there will be more people who passed the test than those that who not, when this system is put in place there is be a large difference in favour of "not passed" or rather "not done" the test, are you just going to kidnap children?

-Day-care providers have to go through college why not parents?
Because parents aren't caring for a large volume of children, generally they care for 1 or 2 not 15 at the same time. Not to mention parents have their own parents to ask for help, Day-care providers have no backup, if they have no idea what to do there is no one to ask for help but google which is what a parent with no experience would do anyway.

-I believe humanity is overpopulating the world.
This is an assumption on your part that you are trying to play off as fact. It's true our population is growing but there is no indication we are overpopulating the world, there is so much land out there that are still completely uninhabited, there is still room for expansion.

-One kid per family with sever punishments per extra kid
You know who already did this? China. You know what's happening now? A severe population decline.
www.indexmundi.com/china/age_structure.html

This graph is supposed to look like a pyramid, very wide at the bottom and thin at the top. Right now it's a weird bi-convex shape which means there will be a very large amount of retired old people living off a pension while the government isn't getting enough money from people working.

You're just going to fuck-up the economy.

And I want you to realize that for the sake of objectivity I've left out moral arguments like say human rights abuse.

I think it's an extreme solution that circumvents the issues.

• Prying into the reproductive habits of a married couple is an issue all on its own, but a testing system would hardly be perfect in my opinion. It would prove someone is good at studying and taking a test, which would hardly qualify someone to be a good parent. If you pushed it further and made it an in depth screening process which could include things like income, occupation, intelligence, genetics, psych eval. etc, it would greatly improve the system but you would then have a whole bunch of different issues that you would be challenged with. I also don't think you can prove someone is going to be a bad parent so it would be unjust to force. A safer bet would be greatly improved child safety services that routinely inspect the child's situation, but then parents would probably object to having their parenting methods evaluated routinely.
• I think if we follow the trend that we have been seeing in developed nations, overpopulation won't be an issue, but I like to remain optimistic in that. Better off families don't seem to want many kids while families in poverty cling onto that survival instinct to reproduce for the benefit of the family. Also, it's been observed that the societies with longer life expectancy's reproduce at a lower rate. As society advances and we get other nations caught up, birthrates should slow down. I also advocate easy access of birth control because when given the choice, most unwanted pregnancies wouldn't occur meaning more resources to go around and less pissed off impoverished people with too many kids.

If you take some shit dirt dirt with shit in it , pour in some water, and filter it, the filtered water can then be evaporated to produce saltpeter crystals.

"cooking" logs in a relatively air-tight less oxygen is good but no oxygen means no fire location can create charcoal.

Sulphur can be found around volcanoes, it is yellow and smell a a bit like farts. When lit on fire it turns into a liquid state and changes colour into a blood red.

Mixing these 3 ingredients at the ration of 100:18:16 (Saltpeter:Charcoal:Sulphur) produces gunpowder.

Not proving or disproving this, but just a few points.

1. This goes off the assumption that time is linear
2. Doesn't bring up the theory of a cyclical existence (a universe much like this one ended, causing this one to begin)
3.This is taking a scientific version of a "god" rather than a religious one making it only technically correct rather than indisputable

Hello science community of funny junk. I have a proposition that may resolve the whole vaccine controversy.
Now, regardless of what studies have been said to show on the effect of the mercury in vaccines have on the human body, people seem to mistrust the vaccines because of the mercury. Although many people disagree with this, I can understand that the parents are probably very worried that their child might be harmed due to the vaccine. So they refuse to take the vaccine but also put their child at a potential risk for disease. So could we not feasibly compile a list of vaccines which do not contain the ingredients that people worry about, thus we can make a list of trusted alternatives that people can use. This will ensure their children's safety, and ensure their happiness. Both sides are happy.

It's pretty damn ridiculous that there are still anti-vax people but that side of the argument should not be humored. So no, I don't think we should find a middle ground for them. I was recently in a class wide debate/discussion about this and although it was in a bio class, a good quarter of them still believed in some kind of anti-vax stuff, including:
You weaken your natural immune system.
The vaccine will "mutate" and get you sick.
Diseases, by nature, mutate so it's pointless since you'll get sick anyway.
The vaccine itself makes you sick.
muh freedom
thimerosal, etc.
It was weird to see when every argument got shot down, people still insisted on the dangers. They could not back up any argument except with "I read that" or "I knew a guy who knew a guy" stuff, most of them incoherently blabbed on about something or another but could not complete a valid (or even slightly comprehensible) argument. What I'm trying to say is that even if we did a pre-vaccination allergy test for thimerosal, it would be pointless. There are already alternatives w/o the preservative (I think some pediatric doses). I'm not going state every reason why people would still be against childhood-vaccination and argue the point, but it really comes down to people's ignorance.

On your second point about MMR and the related side effects:
Any foreign substance can illicit a reaction. By nature, you have to have some kind of response to a vaccine if you are to create memory B and T cells. There will always be a small % of uncertainty that cannot be avoided. Even if they aren't allergic to thimerosal, they could still experience a negative reaction that is dependent of their own health. If you were to strip any vaccine down to the very essential piece required to build an immunity and build a perfect method of vaccination that would not illicit any negative response, you would still get that very small % that would become sick because of their own body.
I'd love to see us get to the point were we could screen for every variable before taking any kind of medicine but we aren't at that point yet and everyone has to suck it up and take their vaccines so we can maintain our herd immunity.

The hydrolized gelatin, to make things clear. Is a substance that can be taken by mouth to improve skin and join health. But some people experience the adverse effects similar to the ones described that were caused by the vaccines. So to gain the trust of the people, we ought to get rid of the metals. To gain the highest possible safety, we ought to get rid of hydrolyzed gelatin. Sure, people may still react negatively, but it will be a lot more trusted if we were to do that. I am no scientist, and if I was I would definitely conduct experiments right away. But from what I have read, I think that the best course of action would be an ultimate compromise.

I actually did my research to see what people worried about and I have found an ingredient which is in even thimerosal and alluminum free vaccines. It is called hydrolyzed gelatin. This has been known to cause nerve damage in some people, often resulting in paralysis. My middle ground solutions is to find alternative vaccines that anti vaxxers can trust. So far the best one I can find is the MMR II vaccine which has no mercury or alluminum in it like the anti vaxxers fear. But it does have hydrolyzed gelatin which I think is probably more worrying than the mercury. If we can make an effort to change the ingredients in order to earn more public trust, then we solved the issue right there. Forcing a vaccine onto someone will only result in more conflict and conspiracy theorists. If the scientists are ultimately out for public well being then they shouldn't actually have a problem with that idea.

I 100% agree with increasing research into safer alternatives, however it's easier said than done. The NIH and WHO have funneled a ridiculous amount of money already into vaccine research and the stuff out there being pushed is the stuff that works. Are there better things out there with lower risks? For some things yes. Will your insurance cover it? Probably not. The best way to go about it is to educate the public and so far that has gone well, but a growing trend of not vaccinating kids is permitting outbreaks like the one at Disney. We are going to witness many more like it, which is unfortunate because it's so easily avoidable.

On a diffident note, how safe do you think you would have to make this alternative? I have trouble believing we could ever get everyone to take any kind of medication if given the choice.

I think if the vaccine was safe enough to not cause potential harm such as paralysis and nerve damage (which has been proven to happen to some patients) or potential autism like the claims that people are making, at least 95% would take it like is what required. I know that it can't be 100% safe, and I know it would be expensive. Nonetheless, if the health care industry cares as much as it claims to, then money should not be an issue. Would it not?

Money is absolutely an issue. It shouldn't be when concerning our health and it's absolutely disgusting to see the current state of the pharmaceutical industry but it's difficult to get around. The whole business runs around a lot of money. You've got companies trying to make money to keep afloat, expand, advance, then make more money; you've got people spending absurd amounts of money on a degree that will hopefully give them a comfortable life; people gambling all this money on research sinkholes and companies that don't want to invest because research could turn out one way or the other. The list goes on; and then there's the average person, making an average income that needs their medicine like everyone else, but a lot of money was involved in making that medicine. I'm happy it's not entirely that way and we've made great strides in research regardless but the health care industry follows the money like everyone else. It's improving along the way, at least I'd like to think so.

MMR 2 has no thimerosal, so this can be promising. The side effects due to allergies is what is worrying people though. In some cases, albeit rare ones according to rxlist, people suffer from things such as paralysis. So what I think the scientists and doctors should do, is look into is find people who are allergic to the vaccine, and administer some sort of alternative that they won't have such a reaction to.
www.rxlist.com/m-m-r-ii-side-effects-drug-center.htm

So in reality, parents do have some reason to be concerned, so we should look into finding a way to get around this.

These people do not care about what's in the vaccines, because they don't understand chemistry. They care that somebody else is telling them what's best for them, and they won't have that.
If you were to do this, you might only convince the dumbest of the current generation, before a new generation of tin-foilers jumps up that finds new excuses and conspiracies to blame on 'the governmen't and 'the big pharma'

The universe both is and isn't infinite. The observable universe is finite and we have rough estimates as to its size.

It might not be infinitely large, just so big compared to us (and growing larger still) that we can consider it that way. And it's hard to imagine another "big bang" can happen when the original big bang came from all the matter in the universe condensed to a singularity. If the universe stops expanding and collapses back to a singularity, maybe we'll get another.

I want to know, because it seems interesting to find out why mint is hot and cold at the same time. Why every time mint is orally present, that water feels a lot cooler. This very well could have something to do with the senses, and there is more information supporting that, of course.

I also feel like that this is an out-of-the-box type of question, and for other people who ask it, I can answer. Like "teach a man to fish"

My guess is that the cold/hot temperature sensation is a result of the anaesthetic properties of menthol. It is local, so it makes things go numb, altering the senses.
