Is this mathematical explanationogical why rain doesn't kill you:

Raindrops form at about 2 km altitude or higher (the altitude of typical rain clouds, eg: cumulonimbus). If we ignore air resistance, the kinematic relation vf=2gh−−−√ tells you that the velocity when it reaches the ground should be about 200 m/s. While not as fast as bullets, this is still pretty fast and enough to cause harm especially if you are barraged with a large number of them, as in rain.

But the above number for the final velocity is wrong. The air resistance (a.k.a. “drag”) is proportional to the square of the velocity, give by

Fd=12ρACdv2

where ρ is the density of air, A is the projected area and Cd is the drag coefficient which depends on the shape of the falling object (0.47 for sphere). While this force is negligible for small velocities, it becomes larger as the velocity increases and eventually becomes equal to the gravitational force on the body. Since air resistance acts opposite to the direction of the velocity, it in this case cancels the gravitational force of the drop. i.e., the drop is not accelerated any longer once a “terminal velocity” is reached. The terminal velocity is given by,

vt=2mgρACd−−−−√

For a drop of 2 mm radius, this equation gives a terminal velocity of about 9.5 m/s which is much lower than the value without air resistance and not large enough to cause harm.

Raindrops don’t kill people because of air resistance.

It should look like this graph more or less... You can find better ones too in google, but you would always find that number '7' is the most common number people say when asked to splurt it out randomly.

Neverland This is interesting, are you a data analyst? I'm leaning towards being a Datascientist, thus analyzing this is fascinating.
vezax
[Laughing]Man~dD 2.1 I am not a data analyst, i am just a math fan *shrugs* i read various stuff from mathematics and physics for fun :p as for my profession i am a medical student ^^
dakoya
Neverland Why aren't you on the path to be a physicist or mathematician? I sometimes wish i had gone down the medical path as well, but I don't want to spend 10+ more years to change careers at this point in life. Although I've read an article about a lady who did so in her 40 or 60s... something like that.
vezax
[Laughing]Man~dD 2.1 Ohh well after becoming a doctor i want to research on genetics and the secrets of life! I love maths and physics but they both are developed fields from my perspective and medical science is a developing field, it makes more sense to research on a developing field as there are more options to research on, moreover life and human body is a fantastic thing to study XD and the last thing.. i find mathematics and physics everywhere in medical field :p the content we study actually have a conplex explanation based on its physics and mathematical functions which the standard books dont give so med students just memmorize things, but if you go beyond and search for more journals and books specefically for its explanations you find mathematics at its core XD
vezax
[Laughing]Man~dD 2.1 *complex *specifically
dakoya
Neverland That is quite a response. I never knew there was so much math and physics in medicine. I thought there'd be more biology and chemistry. That reminds me of my childhood dream to be a scientist b/c I wanted to be a geneticist and a mad scientist to understand why the world is the way it is and most of all... to create the first real life pokemon. 2nd grade was awesome, until pokemon got banned from school.
vezax
[Laughing]Man~dD 2.1 Mathematics is the core of every science out there! And that includes biology too :p The subjects we study in biology all have a physics model. The hemostasis and CVS has various haemodynamics and its almost the same as water dynamics which we study in physics as we have to study about various resistances and how it affects the flow and pressure of blood :p then there are various electron potential gates which are involved in hormonal response and drug response XD anatomy is all about fulcrum and weight :p we need to study filter mechanisms in renal system, respiratory system has air flow dynamics and surface tension! Then comes GIT where you need the knowledge of acid-base and ion exchange to properly understand it (chemistry). These were the non clinical subjects, when you add a deformity in these mechanisms you get pathology based non clinical subjects, then those deformities will produce various changes in bodies in the form of signs and symptoms which can b3 corrected by either tackling the problem or providing an alternate mechanism which comes in Medicine and Surgery ^^ last but not the least Community medicine is full of statistics! Subjects like psychology have almost no mathematical or physical basis, but that is because it is try to explain virtual elements of mind and human behaviour, its almost like explaining the behaviour of characters from a game.. the machine which runs the game and the softare involved in its execution all have mathematics embedded but if you directly study the behaviour of the character you will find no math in it. So that pretty much wraps the medical science :V now not everyone looks at it how i look at it, most of my colleages just memmorize the end result of these subjects without actually understanding the underlying mechanisms and if you study medical science that way then it will be completely devoid of any mathematics or physics.

dakoya
Neverland That's quite a unique way of looking at it. It also brings to mind the idea that everything be viewed as such, well almost anything, thus I think you could apply that perspective to various fields. Does this perspective assist you in your studies? I would assume that if you could see patterns, it would be easier to make correct assumptions if you didn't know the correct answer.
vezax
[Laughing]Man~dD 2.1 Yes it can be applied to many ither fields that is true. Yes it helps me tremendously in studies, i can recollect things in the long term better than others which will be really helpful in my Residency exam :p i also use it in my university exams wherever possible (like in all biochemistry related questions i would directly draw the reactions and structures reacting instead of writing long essays -3- and that was high scoring too!) And yes most of my assumptions are always correct which excites me even more while studying or in class >.>
vezax
[Laughing]Man~dD 2.1 But most of all.. this way of looking at it makes boring parts also extremely interesting and that is quite motivating while studying :p
dakoya
Neverland You sound like you'd make a great researcher. Now here's the million dollar question. It is often shown that intellect comes w/ a price and this price is messiness. So would you consider yourself a messy person? If not, what is a negative feature from such intellect?
vezax
[Laughing]Man~dD 2.1 I hope i do ~_~. I dont believe that every positive thing should have a price, infact for me the negative aspects of an event have a positive meaning so that would pretty much turn any amount of price into a blessing :v That said i am messy person. But when it comes to something i care like a presentation i would remove all the mess :V its just that my lifestyle is messy.. its more like i dont care about my life style so its messy? Intelligence have many negative features, like 'Pride and looking down on others' or ignoring basic aspects of living or lacking work ethics coz you would always find a way to manage at the last moment to get just the 'least minimum to qualify' instead if giving your all, you would rely on your judgements and logic too much and that would cause you to miss certain aspects which are out of box! It makes you a lazy person in general. Yeah one of the biggest negatives would be Extreme Horny nature (its true with most if the High IQ people), Easily influenced by Drugs and aedictions, anti social nature because most of the people wouldnt understand you, and suicidal thoughts as you would often question your own existence and find life meaningless. I said all these based on my personal experience at some point in life and my observation :V
vezax
[Laughing]Man~dD 2.1 I do believe all these negatives can be eliminated if you wanted to, working hard tk eliminate things and a strong passion which drives you will solve almost all of the problems related to intelligence. So really intelligence has no negatives, there will be negatives only if you wanted then to exist *shrugs*
dakoya
Neverland That resonates strongly w/ me too m8. I was the typical smart asian nerd as well and the lazy thing you talked about got to me. Now I don't really care as much and will scrape by w/ w/e. This made me envious and scornful of a friend of mine who seemed to take things in ease while I struggled. Someday I'd like to get back at least some of my motivation and intellect.
vezax
[Laughing]Man~dD 2.1 XD like i said, those negatives exist only coz u let them exist! Get back your motivation and destroy the world :V you wont loose your intellect no matter how sedimentary lifestyle you have, the only thing you have lost with that lifestyle is your mental energy and will power :p most of the laziness we feel is not physical, 80% of times its mental exaustion XD do u have a fucked up sleep-wake cycle? If you have one then correct it! Sleep-wake cycle affects motivation the most! Make it a proper 6hrs - 2 hrs diurnal sleep cycle, exercise everyday in the morning, drink coffe in the evening, watch TedX videos, master things you are bad at and practice writing with both hands XD all these will Increase your motivation. You wont find any negatives of intellect lingering around you then :p
vezax
[Laughing]Man~dD 2.1 *dirunal wake-sleep cycle
vezax
[Laughing]Man~dD 2.1 I know how it feels to just not care and scrape by uwu. But at those time i always remember the words of my chemistry teacher who said me these back in 11th grade: 'you find things too easy and are able to achieve good results without hardwork ryt? So think what walls you could break if you add hardowork to your arsenel!'
vezax
[Laughing]Man~dD 2.1 And yeah if you still continue being lazy.. then take iron tablets and calcium tablets. Its possible that your lifestyle got you hooked up to unhealthy food and not to mention how much nutritional problems a fucked up sleep-wake cycle can cause, those two minerals are easy to get deficient of and always causes lethargy :p when i checked up my blood test i was deficient in calcium and once i replenished my calcium stores i got all my mental energy back. Trust me all the negative characters have some kind of pathology behind it :p
dakoya
Neverland Well I also think I just burnt out after a while. You know when you challenge yourself too much. All those dang expectations! With the new quarter coming up, I plan to have a better sleeping cycle since I only have afternoon classes. You're a pretty positive fellow, do you also find time to socialize and workout. Seems like you'd be too busy to do any of that.
dakoya
Neverland I'll think about some of your advice, change is never easy.
vezax
[Laughing]Man~dD 2.1 There is nothing called burnt out :p that is purely imaginary! But j can understand what you meant. Expectations dont mean anything like really, people or maybe even you expect yourself to succeed! But that is a wrong approach! What you should expect is the failure, if you expect failure then you would know how to tackle it properly.. not to mention achieving failure will help you learn better than success :p eg. If you and your friend are preparing for an entrance exam and you give mock tests and all the test questions came from your strong subjects and his weak subjects so he would score less and you would score high! But that is bad, coz now he knows his weakness and will improve it while you have no clue about yourself! The real entrance exam will be balanced out as there will be both your strong and weaks subjects tested and voila he scores more than you! So burning out is really an excuse you are giving to justify your laziness, you need to face the harsh reality and learn from it.
dakoya
Neverland Lol, I don't know m8. I feel like burning out is sort of like trying to answer that one question on an exam that you don't know. You spend several minutes to half an hour on it, but in the end you answer incorrectly. You just keep pounding at it and pounding at it, and the result is an incorrect answer still.
dakoya
Neverland Anyhow it was fun bashing brains, gotta go sleep now. Maybe we'll encounter each other again.
vezax
[Laughing]Man~dD 2.1 Yes i am a positive thinker, but negative thoughts do come lingering around and many a times they conquer me and i waste months and sometimes an entire year just playing around and doing nothing.. but then in the end i do come back to my sense and cope up with my weaknesses and go all out again XD In my younger days(youn teen age) i was an antisocial person but now that is not the case, i know the value and benefit that comes with a community so i go out of my usual way to socialize with people :V so now i have a good social life, even though its artificial it has its benefits. And i go to gym sometimes like twice in a week, but i regularly go out for walking for hours or jogging.. walking at natural pace stimulates my mind and helps me think so its mentally pleasurable :V so i think various stuffs like Maths, problems, philosophy, medical stuff, animes, stories, porn while walking so its a good physical exercise and at the same time a mental workout! >.>
dakoya
Neverland Wait, I guess I'll be on for a bit more.
dakoya
Neverland O.O how did you wast months to an entire year?
vezax
[Laughing]Man~dD 2.1 Well.. i experience that too! But that is natural and temporary.. you would burn out after trying to solve that (mental exaustion) but after 1 hr of leisure activity you can continue trying to solve it :V if its incorrect then you have a new information.. that you need to think a different route! That burnt out you explained is a short term/momentary thing.. it should have no effect in the long term.
vezax
[Laughing]Man~dD 2.1 Well i got addicted to animes, games, chess, gambling.. and i would only do those.. i didnt study anything in that time and i lost all work ethics! Those were dark periods which i can hardly recollect tbh. But what u clearly remember was that i had no motivation to study or work or even let the daily life go on.. i would wake up whenever i felt like and sleep whenevet i felt like. My grades were high and i had published few research papers so the teachers and residents knew me well and didnt mind giving me fake attendance >.> So yeah pretty much i would spend the entire day inside my room with barely coming out to meet my ex i guess :/
dakoya
Neverland Have you been doing this all on your own, or have you been able to seek assistance? As I grew up, due to my race and circumstances, I felt that others were able to succeed better due to differences in our environments.
dakoya
Neverland Whoa, that is nuts bro. I never knew a situation like that could occur o.o
dakoya
Neverland What brought you out of that haze?
vezax
[Laughing]Man~dD 2.1 I have been doing all this on my own :p I am quite self driven, i have come out of even worse hells XD so yes i came out of that mess of a life too.. if i dont have a passion then i am a human trash lol, for someone like me k need a proper passion to contribute to the society, but when j do contribute i contribute a lot XD
vezax
[Laughing]Man~dD 2.1 Such situations do occur. You should look into the NEET community of japan, what hapoened to me was exactly that. I was lucky enough to get teachers who would cover up my attendance or else i might have failed grades and wasted more years (the exams are always easy though). I am not sure what brought me out of that haze, i did find guilt to be a strong emotion which helped me, but also that i had a goal before joining medical field so my determination to reach there works! Whenever i see that the situation iw going too deep and that if i continue this way further there would be no return i guess thats what motivates me to get out of there? I also have a mild multiple personality disorder as diagnosed by a physician, and it can be a switch in personality which helps me get out of that haze :p
vezax
[Laughing]Man~dD 2.1 Lol one thing i can say is.. even after all that i have more knowledge and experience about medical field than my colleages :p it only prooves even more that my way of studying It is that much more helpfull than the typical memorization XD
dakoya
Neverland Well I guess you were pretty lucky in some aspects. Good job picking yourself back up. Well I really must head to sleep now. It was a good chat m8.
vezax
[Laughing]Man~dD 2.1 Good night :p yes i was lucky in certain aspects, but having soo many other forms of badluck i would call my luck overall as pretty much Normal XD
