actually the angle for maximum range is a little more than 45 degrees, it is about 47 degrees. i may be wrong, but then my former teacher is wrong. he said that my mathematical prove was correct. if you shoot something at an angle 45 degrees, then the gravity has immediately effect on that object. so it lifts of at 2 degrees less than 45.
How old are these students!? I'm in sixth grade and I already know all this (spacetime curvature, E=mc squared formula, quarks, protons, neutrons, electrons, orbitals, atoms, molecules, infinitesimal point, you name it). Sometimes I wonder about the intelligence of people nowadays.
@Comshoin You have to understand that in school you cover every possible aspect of education.When you entercollege you specialize in certain field.You have an entire book in you higher studies for every paragraph you have in school(especially grade 7-10).In school they give you some knowledge about everything and then when you grow up you decide what you choose from.While most of the guys at your age dont know what the hell is going on in school,its wonderful that you know these things already
@Comshoin many courses start from basics, to ensure deep understanding on the subject matter before delving into the complex stuff like relativistic or quantum physics. Also not everyone majors in Physics, but they may need understanding of some of the content for say GeoPhysics or BioPhysics. Also just because you know about something, doesn't mean you have understanding.
@Comshoin you're a young naive grade sixer. you may know of all these things such as the tau neutrino that go's hand in hand with the six quarks as one of the six leptons, you may know of how a electron orbits around a central body of atoms that are made up us six possible quarks, but that is where your knowladge ends, you have no idea where to go from just knowing the vocabulary. and if you could tell me why E=mc^2 then i would be very minorly impressed. don't say smart people are not.
@Comshoin you also say you name it. Tell me what is inside a black hole? Why does the strong nuclear force work, how does life exist? Please don't go out thinking you’re a genius with a little memory trick. Your pseudo-intellegence is almost annoying. Think of it this way. There are always smarter people. Don’t display your lack of knowledge. "Give every man thine ear, but few thy tongue" (Polonius, Hamlet) and for the sake of being melodramatic, you'll learn when you're older.

@XxGypsySniperxX It's nice that 1) there's no such thing as an astor. 2) It's spelled Stephen 3) Books/novels are nothing for professional physicists. You want to be looking at papers and journals.
Some Army Artillery uses a kind of system known as a Mortar. Mortar tubes use an extremely high angle (one in which the shell travels on an arc that is so steep that it lands far shorter than it would if launched at a 45 degree angle). This "lobbing" trajectory allows the shells to land closer than traditional "howitzer" systems. It also has the added advantage of allowing the crew to hit targets at higher elevations from above (where armor and cover is usually weakest.
@BigDickandLittleJon "Defilade Firing" is what they call it. Also useful for when a target is blocked by another object, like when a target is on the opposite of a hill from the gun/mortar, or placed in ditch as the shot can not be made straight on.
my only question is why he had to explain the acceleration of gravity. every person should know it's 9.8(roughly)m/s and 32 feet/sec. if your going to berkeley, surely you already know the acceleration of gravity.
He's a great teacher tbh. But I find the inaccuraty and simplicity quite weird. He's teaching stuff that I learned when I was 14. How old are the students?
Actually I take that back, he's a good teacher, and it seems like a great course. I was just thrown off by the hole rounding -9.8 m/s2 thing. Also how he said Gq1q2/r2 isnt important (basically). Those are all things that are pretty basic in Grade 12 physics... But anyway, my mistake.

@Budman4life They are accelerating which does change their trajectory (causing the satellites to stay in orbit and not fly off into space), but I think relative to the ground they do not increase in velocity.
Imagine a X,Y diagram with vertical and horizontal velocity along its axis. Put an object in this system with a pre-defined total velocity of 100(whatever unit you like).
If velocity straight up along the Y axis=100, and you make the objects path curve to run parallel to the X axis, the object has accelerated along the X axis, without changing it's total velocity.
Can anyone explain why the moon's orbit is moving further away from the earth each year? Since the moon in not accelerating what is causing it? Logically because of tidal forces the moon should drag against the earth, slow down and because of gravity get closer to the earth each year not further away. What is causing this? Because of accretion the earth and moon's gravity should get slightly stronger over millions of years, that too should cause the moon to get closer over time.
I do not think so, mainly because there need be a new force at work which was not considered. This unaccounted force is pushing the moon away, counteracting the force of gravity. What known force found in the lab fits this observation? Mason Peck of Cornell University in Ithaca, New York, USA, has received a grant to study the idea, which is based on the fact that magnetic fields exert forces on electrically charged objects.
This guy is an idiot. He doesn't talk about centripetal acceleration, or how the vertical displacement before a projectile is launched affects the resulting horizontal displacement. I know this isn't mathematics based but come on.
We COULD go to MIT or similar things, but they don't go through as many things. Because this isn't mathematics based, we get to learn a lot of things quickly - rather than going in to the depths of certain things... This is our form of social science... ;)

Also it is apparent that physics is not proved by demos but just writing stuff on the board. Let's get over the math AND the demos if he is just going to throw chalk in the air.
The mathematics is a such a fundamental part of physics, that you'd have to learn some of it, even for the conceptual understanding. Besides, a four year old could do the maths he shows. E=hv , E=mc^2 , these are things important for the conceptual understanding.
The demos are more likely to stick with you as a memory... What better way to show that 1+1=2 then that of the apple-addition? ;)

I'm not sure if he fully understands geology with his whole oil = less gravity?? (as the oil is actually stored in the rocks which are typically a sandstone or limestone) but other than that it was an awesome talk.
im sitting my standard grade physics on tuesday (dont know what the equivalent is in US, but im 15 to give you an idea) and most of this stuff i already knew or was able to grasp it. i really like the way he teaches it though
The reason for not understanding is the missing step. If I explained to you, and but left out a key step, then you would have great difficulity understanding it. This has a lot of basic concepts in a sense. Hardly any advance equations. Most of this I have also learned (I am 15 aswell) Or atleast that is my understanding.
Yeah it's not really meant to be an intense course. Just a high-level overview to give those otherwise disinterested in physics exposure to the precepts.
Many students at my high school also learned of E&M in ninth grade, but only certain students were permitted to do that in a course called Algebra-based Physics.
I am in Canada, we also studied gravity in 6th grade, and fished off electromagnetism, and eventually the general theory of relativity and quantum mechanics by 8th grade. However, we did electricity, circuits, applications and so forth in 9th grade. It all differs from school board to school board, but what really matters is that all of the basic knowledge which we have the right to possess is given us by the time we graduate is it not?
Yes, that IS what really matters to us and is what is most definately not accomplished because we live on a farm controlled by those so rich they don't appear on "the world's richest" lists, and their aims are not our aims. Its diminuitively called 'Hegemony' (eg Chomsky) but more properly addressed as New World Order or Whore of Babylon etc. video.google The Secret Behind the Secret Societes or Forbidden Secret etc.
hmm so a theory that unifies gravity with electromagnetism isn't interesting? If something that einstein tried to do for 30 years but failed to succeed doesn't interest you, i'm incredibly curious as to what does.
It's not really a unification, though... It's only a valid approximation under certain conditions, right?
It'd be hard to truly unify gravity with any of the three other forces, due to the fact that we haven't even got a well established theory of quantum gravity... ;)
This comment has received too many negative votesshow
The level in the US is obviously very basic. Maybe this explains the overall economy decline of that Country. Sad, they got the best European Scientists at the end of WWII.
Perhaps another war is needed to steal more European Scientists.
physics lectures for law students!!wtf!! I SEE ,IF A SATELLITE PLUNGES TO EARTH AND TAKES OUT A BLOCK OR TWO THEY' CAN LAUNCH A CLASS ACTION AGAINST GRAVITY...
Richard Feynman and Murray Gell-Mann were both americans. If you don't know them then you know nothing about the history of physics. We have great physics programs in various different colleges. We just have terrible high schools. No child left behind is code for "lets dumb down the high schools so every idiot can get an A with little intelligence and let the smart kids' minds go to waste"
Smart kids are forced into a dumbed down curriculum so the less intelligent kids can pass.
That doesnt mean you are allowed to be an A Hole about it. It would be nice to learn that with all of YOUR intelligence you might be able to learn a little about courtesy.
Heh heh...Yea, that's why we are the lone super-power, the strongest economy and the best standard of living in all the world. Other-than-that, I suppose your'e correct
You're stupid simplas. If you were smarter, you might understand that it's a global economic decline, and that it's a domino effecting the whole world. Lets say a rubber factory goes under in Germany, the effects can be felt around the would in very little time depending on how big the factory is. Now some factory in Brazil will go under too now that they don't have someone to buy their product. See how it work guy? BTW the U.S. doesn't like war anymore, we all hate that Bush did what he did.
I hear you. Even if one doesn't find this interesting, one should show proper respect to the teacher. Too bad college is more about partying than learning...
I wish the camera guy was more awake while filming. It would have been nice to get closeups when the professor wrote something on the board and it also would have been nice to have things in focus. Still a great lecture. I learned a lot.
The lectuure is great. But one thing I don't understand, those things which he show are sooo easy, I can't believe that students in USA learn those things at University... . Lecture is great, interresting, but those thing are very simple....
Yes, it is intentionally a LOW LEVEL Physics course for those who are not very Mathematically inclined. It is NOT supposed to be your standard Stage One University Physics Course.
@rijkent55 I understand its meant to just be the basic concept... But really whats the point? If they don't have to understand absolute basic algebra, there is no use to having any of the concept. There's no application for it.
More physics please and less terrorists, n. korea, how US made V2 rocket <- lol, etc. From that inteligent prof. there should be more objectivity. And about that other lession about nukes, when he says 32 or 26 thousand ppl died in chernobyl - come on, read some facts, u can start with wikipedia. Despite that, excellent lectures
if you had listened to what he said you'd know that he meant the people who died of cancer inflicted by the radiation that WEREN'T recorded since they just looked like normal cancer patients.
wikipedia most probably only mention the ones that died in direct cause of chernobyl.
he explained this perfectly. you didn't understand it. ergo, it's your own fault.
Big Thank You to Dr Muller and UC Berkeley for putting this on youtube. Hope you students appreciate the quality education you are getting. What a great professor to have. Call me a nerd, but this is great video.
This teacher is so great! I can't believe people actually can't wait for him to finish before leaving the room. I'd stay and listen to him for a couple of days and forget about eating, drinking or going to bathroom.
The way he explains stuff is amazing, I wish I had teachers like that.
lol about that hallow sphere i was about to ask him that if i was in the class if that would be the same mass.. cuz I figure without taking any physics classes that the gravity is by the size of the object with little mass in center to balance out everything not the mass inside it.. and i was right! heh
I guess those peoples are not willing to learn "high&tough" physics. It's "physics for future presidents" and since politics don't have to be really wise these lectures are not difficult. However I quite enjoy it.
Whomever asked the artillery question: its not 45 degrees. You're professor is correct when describing the use of tables in the field artillery. The bollistics of the round and charge used determine the optimum range--some rounds are even rocket assisted (rocket assisted projectile or RAP) all have the optimum range determined by a tabular firing table--45 degrees is NOT optimum.
I leveled buildings and jumped out of airplanes. I have two bronze stars and a shrapnel collection. Using the objective form of a pronoun in place of the nominative form on a forum that is little better than a text messaging system doesn't really concern me.
Note: are you seriously trying to correct my grammar with a barely coherent sentance? "Buddy?" You must be from California.
I love getting castigated for spelling by people who are incapable of crafting a proper English sentence. Again, do people really come to UC Berkly lectures to troll?
Trolling can be done everywhere. What's more, this is a public website, with no comment moderators. And don't forget that with the new Audio Previews is way more fun to type silly things :P.
I hate how he just throws out arbitrary numbers and "facts" all the time saying its close enough, but I guess its ok since these future presidents dont really have to know anything. However what I really dont like is the way he put down Anders Celsius' contribution to the celcius scale in one of the earlier lectures, saying it was some sort of french scheme. Oh, and why the hell cant you americans just adopt the SI-units? they are better in every way.....
he's trying to make it easy to understand, and math can make things boring. if the concepts are interesting, the students will explore the mathematical part on their own. and about the si units. i agree, but it's hard to change the minds of 300 million people
those stupid cunts not paying him attention at the end when he does that card trick, so rude

The mathematics is a such a fundamental part of physics, that you'd have to learn some of it, even for the conceptual understanding. Besides, a four year old could do the maths he shows. E=hv , E=mc^2 , these are things important for the conceptual understanding.
The demos are more likely to stick with you as a memory... What better way to show that 1+1=2 then that of the apple-addition? ;)

Essence of space is that it actually avoids matter and that is what gravity is. It is a feature of space caused by matter not the other way around.

The reason for not understanding is the missing step. If I explained to you, and but left out a key step, then you would have great difficulity understanding it. This has a lot of basic concepts in a sense. Hardly any advance equations. Most of this I have also learned (I am 15 aswell) Or atleast that is my understanding.

I am in Canada, we also studied gravity in 6th grade, and fished off electromagnetism, and eventually the general theory of relativity and quantum mechanics by 8th grade. However, we did electricity, circuits, applications and so forth in 9th grade. It all differs from school board to school board, but what really matters is that all of the basic knowledge which we have the right to possess is given us by the time we graduate is it not?

It's not really a unification, though... It's only a valid approximation under certain conditions, right?
It'd be hard to truly unify gravity with any of the three other forces, due to the fact that we haven't even got a well established theory of quantum gravity... ;)

Richard Feynman and Murray Gell-Mann were both americans. If you don't know them then you know nothing about the history of physics. We have great physics programs in various different colleges. We just have terrible high schools. No child left behind is code for "lets dumb down the high schools so every idiot can get an A with little intelligence and let the smart kids' minds go to waste"
Smart kids are forced into a dumbed down curriculum so the less intelligent kids can pass.

You're stupid simplas. If you were smarter, you might understand that it's a global economic decline, and that it's a domino effecting the whole world.

Now some factory in Brazil will go under too now that they don't have someone to buy their product. See how it work guy? BTW the U.S. doesn't like war anymore, we all hate that Bush did what he did.

Whomever asked the artillery question: its not 45 degrees. You're professor is correct when describing the use of tables in the field artillery. The bollistics of the round and charge used determine the optimum range--some rounds are even rocket assisted (rocket assisted projectile or RAP) all have the optimum range determined by a tabular firing table--45 degrees is NOT optimum.
You're thinking mortars.
