Math and Physics of the Everyday 

Are you a engineering?

Yes I studied engineering

In kleppner was a task, where rock was thrown from a peak of hill which slopes downward uniformly at angle a. For maximum range, angle was pi/4-a/2

Hiw did you animate. It was good.

​@@wenslo8514and 🎉n nmj😂njk😅 much 😅n😂jimk 2Jimi m 2:48 v 2:56 s

yes. in a sea of clickbaits sometimes we find an island of awesome content

Recognised 😊 I wanna ask something cuz i rly dont get it 4:45 1st, how do we know which distance we should chose between two points? Like, how do we find the correct angle of the line? In this example to me it looked like the bike lenght was assumed beforehand, and then that lenght was used to find out the direction. Sure tho we can assume about how long it is based on the fact that bikes tend to be made within a small range of lenghts But then 2nd Why wouldnt you find the same going the other way? If the line fits in one direction than it would fit in the other since its the same lenght between the two wheels no matter which direction the front tire is facing Idk, i assume im missing something, but it really doesent make sence to me why you wouldnt be able to fit a same line of the same lenght all through out the two bike tracks. If anyone can explain this to me, i would greatly apreciate it Ill tell you a joke in return Idk what else i can do on here to pay ya back( maybe a story, or a concept, as you like) Have a good day

OdiumOdyssey Physics and math are used in almost everything in life!!! It’s fascinating!

Im an emergency room RN and its also used in trauma medicine when we consider the mechanism of injury, the trauma surgeon considers the physical properties of involved tissues and the forces of their injury in predicting possible injuries (i.e. bones may withstand compression well but react less well to torsion)

I cant figure this out, so im sending people the same coment question with hope to get an answer 4:45 1st, how do we know which distance we should chose between two points?

I love maths too:D

Math is magical

Love??? More like addiction. I am bad at a lot subjects not related to math because of my addiction.

You're in love with it, cause it is reliable... Let's be honest here...

@@Super_Smash_Dude same I love math

That was excellent

I always love reading coments like this one, because they give me a sence of hope for the human race Id like to think that most of us have something which we are fascinated in, and some person or people who we apreciate without any pretence, without any jelousy or envy, even if we sometimes might disaguree, but instead filled with curiosity to learn from one another Im sure he would apreciate reading this if he did read it Coments like this are proof that there are people in the coments who treat other people like actual humans instead of just abstract messages without a source, because it feels like most coments i see in general are written by people who at that moment fail to recognise that they are writing to an actual human beeing with feelings and other opinions besides the ones outlined and so on Anyway Have a nice day

@MalkuthEmperor ya kno looking back at this comment 5 years later it feels just a little silly because I probably look like a crazy person to a lot of people but I remember when I found this guy and he was small enough that I knew there was a chance he would read it and I genuinely loved and appreciated all the content I had seen from him and I know how most people do kind of just comment into the void without much actual substance and I just wanted to let it be known for what it was worth that I saw what he was doing and the level he was doing it at and who knows if he ever read it or not but I will always be that weird person who speaks how they really feel even if everyone judges me for it or I'm misunderstood at least I tried ya kno...

I have that very thought everytime I'm doing problems in a textbook.

But that doesn't prove that she did it? Although the numbers are astonishing, how can someone 'induce' a heart attack and let alone the probability of someone doing something so evil just to "save the day?" This makes no sense

​@@learning_with_irving4266that alone doesent prove it indeed. A greater likelyhood of something happening does not mean that something happened or will happen for cirtain, so without any further evidence, it would make sence to convict her But the stats themselves would provide at least some correlatory lead

You were right about the milion, but idk when he got it, whether it was in the neer future Tho neer is relative Anyway, have a nice day

Maths is beautiful! It's like solving a puzzle. Maths allows you to use the little that we know to figure the things we don't know. We use maths to see the connection between things around us. It allows us to understand the world around us. It's also amazing to consider that without maths, we most likely wouldn't have chemistry, biology, programming, computer science, physics and even more, because all the things people used to discover all of these things were built by maths! None of these subjects would be nearly as big as they are now if not for maths. I thank God for helping me see the beauty of maths.

Your best bet is to probably major in either physics with an emphasis in atomic/molecular/optical or condensed matter physics. But a degree in applied mathematics with an emphasis in mathematical physics would be good too.

i was looking for someone else who saw that

Better. Make a book about it.

Better. Create a community for people to learn the major prep way. Beyond just school, low to no profit organization that allows others who have a true passion to learn about lifes complexities to meet up collaborate and learn in an environment that isnt as assessment enforcing as school can be. And privides a collaborative environment that promotes togetherness, teamwork, and a better understanding of how concepts apply in real world situations. I feel like if something like that exists a lot more people will become more open minded and at the least have an appreciation for mathematics and physics. And at the most everyone will realize how cool engineering really is and younger kids will have a better premise to what they can expect to gear up and prepare for the work it takes to getting into the field of study. Or they can realize the work and not get into it lol. But come out still with an appreciation and understanding that they cant simply compare any other work load in a common business job to the work it takes to build such complex modes of understanding within physics and mathematics.

Nice! I’m doing number theory right now. I think you could probably move on to real analysis as well (assuming you have the calculus background).

Right!?? That was so stupid, getting fired for doing your job well..

Noooo, too boring. Keep it Physics/Math oriented :)

The next video is going to be stats related. It won’t be the typical ‘stats careers’ or ‘the statistics major’ type video but hopefully people find it interesting.

MajorPrep Nice!

Lmaooo

If you mean more variation in amplitude then you are correct.

You need a solid understanding of algebra and trigonometry to take aphasics class and be succesful. Intro physics won't show you how to describe physical phenomena in there true form(calculus/differential equations) until university level. If you are a physical science major or engineering.

Nope. You need to know how to use what's called the power rule in differentiation. But that's really easy and that's all. Classical mechanics is mostly pre-calculus stuff. Lots of tricky algebra and clever trig applications though.

find videos on youtube specifically pertaining to these requests, by searching them up. and check out Rishab Jain who got into MIT & Harvard, and people's maker portfolio videos on youtube (there's a ton of examples)

i'm also 15. extracurriculars for engineering: FRC & FTC are the best (pertaining to mechanical, electrical, & computer engineering). Science olympiad and TSA could also work if that's NOT your main thing. F=MA & Usapho are a physics olympiad. Carrara got into MIT & UC Berkeley, check out his channel too. math is helpful for any STEM major. math extracurriculars: AMC (only helps if u AIME qualify), state math contests, college math contests. Go to your local math club or school math club. For all of these, google search & youtube search your questions pertaining to all these names i gave you. really the thing that will help you the most is not me typing out a paragraph, or even 5 paragraphs, it's that you USE this info by searching it on youtube & google.

40 deaths occurred while gilbert was present at the hospital (257 shifts overall during her time there). When she was not present only 34 people died and that was out of 1384 total shifts. The percentage of deaths happening on her watch was really high (kind of like having a coin that keeps coming out 9 heads out of 10 flips).

You take the direction the solid line currently is at any arbitrary point. Extend a straight line in both directions from multiple points on the solid line in accordance with that in 1 direction, the distance until they cross the dotted line will always be the same (in some cases, will cross the dotted multiple times, only the distance that is in every measurement matters), this is the direction the bike is heading, and the distance is also the distance between the front and back wheel in the other direction, the distance will not be equal, and in fact may be infinite/undefined (they never cross), this is not the direction the bike is heading Using the example in the video, I measure the distance at several points according to this method. The distance he has going to the right is aprox 3.5 centimeters on my monitor (not the length of bike, but is the onscreen model, would be scaled up in any actual situation) taking from the points he picked in the graph, the first point is aprox 4.5 centimeters from the dotted line in the other direction, the second aprox 3.5, the third aprox 2.5 while it ALWAYS touches at 3.5 cm to the right

That is correct, because as soon as you step back that angle decreases. I imagine it like standing in front of a skyscraper. You'll appreciate how tall it is the most by standing right under it and looking up.

Are you sure it was created? You can't state that like it is a fact.

Haha yes I do! Thanks for noticing

dandysixties it sure is. But it looks like someone had turned it into a GIF

Your question doesn't makes sense. Are you saying you want to work in physics? In that case you need a Phd in physics. Depending on what you focus in physics will determine what type of research in physics you will do.

just put your hands on the seat to steady you if youre 12
