  • I'm sure you've all heard about Isaac Newton and that apple that fell on his head and how that was a huge deal to our understanding of gravity. Well... let's talk about that. In this episode of Crash Course Physics, Shini sits down to talk about the realities of the apple story and how Newtonian Gravity is more than a little important.

    Physics is, I'll admit, my weakest subject. I used to really like it, but soon found it confusing, and complicated. However, these simple, fun, enlightening crash course videos (and some others as well) have helped me grasp certain concepts I could not get before! I actually started liking the subject again mainly because of these videos. I have a Physics exam tomorrow (CAPE Physics Unit 1, paper 2 ; contributes to 50% of my overall grade) and I'm thankful that I was able to learn from at least some of the videos in the series! So, a big thanks for starting a Physics series, +CrashCourse ! :)

      Most videos in this channel have that problem. They try to cram one hour worth of information within 10 min. Unless you were very familiar with the subject and come here to refresh your memory. These videos are not a shortcut to learn physics quickly as many people think lol

      @frankschneider6156 Před 8 lety +1

      *****
      I strongly doubt that you are older than me (at least physically). If you feel you have a math issue, that's ok. Can happen, but even if you have a "busy" life you can do something about it if you want to. Try EdX, Coursera or Khan Academy, or do it the old fashioned way by simply using a textbook. Yes this can be done, even if you have a "busy" life. But that's perfectly up to you.
      But what is NOT ok, is to brag around: "I'm so bad at math (look at me how great I am)" giving young people the impression, that this would be perfectly fine. That's similar to saying "Look bro, I'm the coolest dude, because I'm illiterate".
      Being bad at maths is ok, but nothing to be proud of. If you're bad at it, try to solve to but don't give kids the impression that being uneducated is perfectly fine.

      @frankschneider6156 Před 8 lety +1

      *****
      If you would be ashamed of your lacking maths skills (as you should be), you wouldn't have mentioned it. If you are not, you obviously deem the status of lacking mathematical skill to be socially acceptable, which it is of course not. If you write in the first sentence "I am an idiot", don't wonder if people think of you as an idiot.

    • @shuriken188
      @shuriken188 Před 7 lety +14

      The problem with a CC mathematics course is that math involves more repetitive practice, rather than just concepts and an example or two. It's not impossible, but it would have to choose between staying true to the Crash Course format and teaching mathematics thoroughly, new concepts far between.
      That being said, I would enjoy CC math.

    Nice video again. I wonder how far in advanced physics this course will go. I would love to hear about the Maxwell-Equations, thermodynamics and quantum physics in this style. Even if I have learned about most of the topics I like to hear, see or read about them again and again. Btw it's said about Newton that he repeated the old Greek mathematicians before he came up with calculus. I think constant thinking about and working with science is the path to mastery in ones field and there is no higher joy than finding out how the world we live in works.

    Question. Has anyone thought of replacing
    "F" for applied Force with "E" for applied Energy? Eg vs Fg?
    Would that work? If we were to know how strong or weak the “gravity” is, then
    we would know how much energy is being applied from within a planet or black
    hole. Cause, without energy there is no gravity, magnetism, fields, waves,
    motion, etc. After all, Force does not exist "physically" in the same
    way that an object with mass does. "Force", as we know it, turns out
    to be nothing more than an expression to express an idea like one would use the
    word "Love" to express one's feelings. Meaning, Force or Net Force
    does not push, pull or work for that matter.

    If you dropped a bouncy ball from a height of 1m on to cement and did this little experiment on Earth and Mars on which planet would it bounce higher? I really don't know if any one does please tell me. Thanks

    I have an idea. Let's make an instructional video series. We'll find the fastest talker we can find and then edit out all normal pauses that a speaker generally makes while speaking. Oh, and we'll use graphics but only flash them on the screen momentarily and then quickly to the next one.. We'll get lots of views but the comment section will demonstrate that nobody was actually paying attention to the topic!
