pov: he made this for his students but your teacher recommended you watch it for an assignment so now you're watching a random teacher explain physics to you (thx for the help btw) :))
I cannot even start to tell you how helpful your classier. I particularly like the real-life examples that really help break down every theoretical concept. As I am learning about Dynamical Systems, going first through your classes really give me the knowledge I need. Thank you for your great work and I hope you continue !
thanks!! I need these kind of videos for my "bored" kids who tune out. You make science soooo understandable! More Physics please!.. If you ever do scaled down programs for middle school physical science, I and many would probably love it. Thank you for generosity in sharing your teachings!
Physics was actually first quantified during the golden age of islamic civilization (9-12 century). The first scientist to officially use experimentation and observation was Alhazen, and he invented the camera and was considered the father of optics. Another scientist in the famous House of Wisdom in Baghdad discovered the accurate distance between the earth and the moon. In fact, it was such knowledge that the European advancements took base from.
For someone who's not going to school for physics, yet I would like to learn more where should I be looking for more information that my fellow students would be learning in class. Just looking to get more knowledge on the subject because it's very fascinating to me. Never had the chance to learn it in highschool.
Great video, but would you really become a different age if you went faster then light, or would you just see what happened before because the most recent light can't catch up to you? Then when you approach speeds slower than light, you would see the more recent light, as if nothing changed. Other that you probably being crushed under the force of the speed of light, theoretically you would not go back in time.
at 7.51 you mention "time dilation" no one has prove that so far because, "time" is abstract. And as I know you shall know that abstract things are out our domain. Thanks
Time dilation has been proven, in several instances. The one that sticks the most in my mind was several experiments with clocks that were accurate and consistent to an absurdly small fraction of a second. One was left on the ground and another traveled on a plane (or jet) at high speeds. After all was said and done the clocks had a significant time differential (of about a handful of nanoseconds, which was quite a bit above the uncertainty for the clocks involved.) There's been other confirmation experiments, maybe look them up. (Such as the effect of...what were they? Some kind of particle that has a noted and consistent decay time, which were shown to have a very different but strangely consistent decay time when traveling at relativistic speeds.)
+gene546 The Lorentz transformation is a very real thing. The easiest proof for the time dilation is probably given by the myon. The myon is created in the upper part of the atmosphere. From labs we know that it have a half time that will allow it to reliably travel around 600 meter before decaying. Yet we see these myons travel many km. This is possible because the myon travel close to the speed of light and are therefore affected by the time dilation.
If force equals mass times acceleration. Why isn't the multiplication sign included when writing the formula? Is multiplication just the default operation when writing two variables?
That's correct- when using letters as variables (I.e. m and a ) , its standard to omit the times symbol in case it is confused with the variable x so letters written next to each other represent multiplication
***** You need to have some math before you start physics. Go back to the beginning of algebra. 2+3=x, What does 'x' equal? . . 7-x=2 What does 'x' equal? . . . and so on. Take a math course and get good marks. Also Petter, all science must be learned from the beginning. In fact, the Scientific Method is bottom up logic. The first step in the Scientific Method is Objective Observation. Galileo wanted to understand motion so he observed a wagon moving along a road. He saw that the wagon moved a certain distance in a certain time. He measured the distance and the time carefully and then he divided one number by the other. He realized that all motion could be thought of as distance divided by time. That was the beginning of modern physics. Unfortunately, the guy in this video does not begin at the beginning.
bimmjim The fact that the structure of the Scientific Method is "bottom up" as you say, shouldn't dictate how we ought to do our learning. Because, human thinking isn't bottom up. It seems to be the opposite, really. Moreover, I wouldn't ever want to learn anything in a strict bottom-up way, unless, for a specific purpose where it is actually necessary. Besides, it's more much interesting to know a little bit of many different fields (being a generalist) as it is, in general, much more powerful because, like in the real world, everything is inter-connected and it is becoming increasingly clear, that the next stages of our evolution will not be shaped by experts in a given field, but by those who can connect the dots. Of course, if one wants to become an expert in, say, physics - it's OK to learn it from the bottom up. But it's not my preferred way of learning :)
+Petter Thowsen Generalist are useless and the future is not gonna be shaped by them. Actaully its the other way round. We are going to need more and more specialists, at least in the scientific fields. If you aren't a expert you simple know nearly nothing. When you start climbing the mountain that is a field. You will quickly find that what you thought was the top, was only a very small Plato and that what is going to be useful is way farther up. And its just going to be more like this in a world where we start to apply things like high energy physics, quantum mechanics and maybe even dark matter.
sumsar01 When it comes to fields like physics or biology, which may be very complicated, I suppose we do need specialists. My point though is that, the universe is connected. The plant contains the sun, the earth, the water etc. You cannot understand the plant without understanding everything around it. (For example, to understand how it came to be, you must ultimately understand chemistry, physics, geology, biology etc). So, saying "generalists are useless" makes no sense to me.

AHAHAHHA
I used to watch you when I studied A level Biology - now I'm back to study physics! Thanks for your great videos!
Fun and clear.

This is just so great! Thank you so much Sir! You're simply amazing!
Dude, make more videos. I like the way you explained it. Keep going...
so awesome and creative. thanks a bunch
This helped me so much! My teacher was impressed. Thank you!
thanks!! I need these kind of videos for my "bored" kids who tune out. You make science soooo understandable! More Physics please!.. If you ever do scaled down programs for middle school physical science, I and many would probably love it. Thank you for generosity in sharing your teachings!
Love your channel Mr. A. Keep uploading stuff!
great work sir. I subbed. Cant thank u enough.
love your videos
You are better than most of the teachers in our schools.
Loved it! Thanks a lot!! It was really helpful!

Thank you i finally partly understand physics!
Love this!

I love physics
Thank you Mr andersen. You are a cool guy oh yeah!
it's a warm summer evening in ancient greece
this was very helpfull
Science is fun when you have an enthusiastic teacher!
My science teacher made me watch this for homework and take a test on it.
I love you
Samajh Mein To Kuchh Nahin Aaya lekin sunkar Achcha Laga
the Mythbusters sort of disproved his third law with the blow your own sail episode.
Nice video
Phun download link please
How did you get that 26.9 for the conversion. How diid or what did you solve to get that sum?
I’ve never taking physics before. Which one of your playlists should I watch?
All!
This is interesting and is fun an app?
is that "simple pendulum"..?
the bigger question is...What is love?
Flst123 baby don’t hurt me

thanks for your response, I keep my doubts until I work my thoughts.
+gene546 With that mindset you shouldn't even be on this video.
What do you think it takes to succeed as a physicist? (Question to anyone who has an answer)
I will go at the speed of light and then comeback at 31st century to see the games from future

you have a website for bozemanbiology but you should have paulphysics lol alliterations :D
My brain hurt it nigh 1 am not a good time to learn about physics
Hi, would you like to create a house for us?
Who let bro cook
Tbh Mann your kinda boring butt thanks
