how does stochiometry help us in real life?

Depends on what you do or care about.  Do you want to know how much sugar to add when making wine to reach the desired alcohol content and/or "dryness"?  Do you want to know how much acetylene and oxygen to mix when welding?  Do you want to fill a scuba diving tank?  Do you want to know how much vinegar and baking soda to add when making sponge toffee so it is neither bitter nor sour?  \n\nThese are just a few examples for people who are not scientists at all.  Zillions of reasons more.

It's an optical illusion. When it's near the horizon there are points of reference within your field of vision so your brain can correctly assess the size of it whereas high in the sky, there's nothing for the brain to use to assess size.

This is an 'empirical question'.  That means you can perform a test (experiment) to determine the answer.  Do the test.  Weigh yourself. Take a one hour bath.  Dry off.  Weigh yourself again.  Be sure not to get your hair wet because you can't dry that off quickly.\n\nLimitations may include the accuracy and reproducibility of your scale and its ability to measure very small changes.\n\nTry it!\nGood luck.

Search "body mass index". It'll show you how to calculate your "suggested" weight range.

Go to this website, enter your information and you will get your body mass index, which tells you whether you are in good shape or not.  It's really cool.

Your book,the reading table,the trees,themountins,a monument,a fridge or an airconditioner ll contain right angle.Actually there is a branch of mathematics known as Trigonmetry which helps us to find the exact mesurements of high structures without actually measuring it with the help of the right angle they form with the ground

Not really. Try weighing yourself with your normal amount of clothes (shirt, jeans, shoes) and then again without anything. For me, it usually shows less than a 1.5 lb difference.

Science is an attempt to develop a set of tools that permit accurate predictions of natural phenomena.  It is a process of testing hypotheses and then tuning the hypotheses to match the observations made during the test, making new predictions with the hopefully improved hypotheses and testing them again.\n\nAll observations constitute a form of measurement (not necessarily quantitative measurement). Without measurement of observations, the cycle breaks and what would otherwise be science is merely random guessing. \n\nEven an "educated guess" relies on measurements made throughout ones life.  For instance, if I guess that if I let go of an orange it will fall, that relies on my experiences of observing things falling.  Even if I have never measured distances or acceleration or velocities or travel times of a falling object, I HAVE noted that "most of the time" things fall.  That is a measurement.\n\nQuantifiable measurements allow us to make predictions with greater precision. "This orange will hit the floor before you can close the door," for instance.   Numerical measurements can also help us see more complex relationships between observables that we might otherwise miss.  These allow us to extend hypotheses in ways we might not be able to.

Yes, I think so! More fuel to feed our growing bodies-- mine isn't growing much anymore though! And plus, adults' metabolisms are usually slower than ours... :-)

Yes, go to a physcian. Ask them to perform a skinfold test. They will pinch a roll of your skin on your side, upper back and belly button. with calipers and get readings from that. They will then weigh you and get calculations from that.

Depends on a persons metabolism

Yes. Nearly the entire world and all of the scientific community use the metric system. In order to foster the idea of globalism in the US we should unify our measurements.

don't really know if this will help or not :                                                                                                    http://www.netdoctor.co.uk/ate/health/growth_metabolism/600231.shtml

haha is this biology lol well its easy take mass by inital mass then divide by weight

by measuring your BMI!!!divide your height on your weight and look up the normal range!!!!but if people can see that your figure is great ,why the worry!!!

i'm not that good at it, neither spiritually or religiously... the first time i learnt of this thing is by reading the book "Da Vinci Code" *blush*... when Langdon thought of his arts lecture in university and recapitulates everything... i do think it is amazing... \n\nof coz from the point of view of religious ppl, they may say that it is one of the greatest evidences that someone is behind the design & creation of this whole universe... and it is only shown by means of as minute as PHI... naturally everywhere but unaware by most ppl~\n\nwhile from the scientific point of view... it may simply be the most efficient ratio for things to work, or things to be perceived as most beautiful or charming... it's just like ppl thinks it's better to go in a pair instead of odd ones out... and when sometimes ppl think sth is out of ratio, maybe they can't say anything certain before they really measure with equipments, yet they will always say "it looks strange/odd/unnatural because that particular part is too big/small/long/short when compared to the norm"\n\nso i think it's real, but why it is real depends on ppl's belief
