Use your knowledge in Newtonian mechanics to answer the following questions: 1. What was before big bang? 2. What's dark matter and how is it related to the meaning of life?
@@baab4229 First, I know you're joking ok? I just want to answer something anyway, lol. 1- How much time before the Big Bang? I mean you could literally say 'singularity" and that wouldn't be wrong because that's what existed before the actual expansion, right? 2- listen fam, Dark matter is something we can't see but we know It's there because of how It interacts with the formation and rotation speed of most galaxies. Also, It doesn't have anything to do with the meaning of life, unless you set something related to Dark matter as the ultimate goal in your life, since the meaning of our lives is whatever we want It to be. Not a physics major, so sry for any dumb shit I might have written.
Milton Marques for part 1, you’re right that there is a singularity. But there is no time time before the Big Bang. Therefore, nothing can happen ‘before’ the first moment in the universe
@@bobross5716 But how do you know the Big Bang was the first moment of the universe? Isn't it a model of how the universe became what It is today rather then an origin explanation?
@@Haki145 It is a model that is about as close as you can get to an origin. When everything was a part of the singularity, everything was at one singular position at the origin (sort of x=0, if you want to think about it that way). Since according general relativity, space and time are one and the same, this means time was also at its origin. If "space is equal to zero" here, what that really means is space-time is equal to zero (although GR breaks down at the very first moments of the universe, so who knows maybe it is wrong). If that's the first moment in space-time, there cannot be a moment before it. That's how I understand it anyway. Whether or not there was really something before that (multiverse, big-bang big-crunch cycle, etc...) is outside my realm of knowledge.
Prof: "Exam is like your homework problems, piece of cake" You:"Those take me like 5 hours to get done" Prof:"Try being better next time?!" Man profesor I never thought of it that way, when you put it like that it sounds easy.
In my second year undergraduate physics degree in the E-M course everyone was getting like 30% scores on the assignments and were taking like 4-6 hours each week (we had maybe like 8 or 10 concurrent courses) and the lecturer took time out of one of his lectures to explain that the problems took him 40 minutes to do so we should easily get them done in an hour.
It is perfectly possible to get both positive and negative values for time (I'm talking about high school physics lol) when the quadratic formula is used. Of course, the negative value isn't included in the answer. (Correct me if I'm wrong haha)
@@shahedhossainimran yeah sometimes if you forget to ignore vectors and stuff you can still get the right number, u just gotta take off the neg sign lol

In Engineering we always used to say: *Getting 51% is 1% wasted effort.(*)* And we truly, genuinely meant it when we said it. Our exams were usually _brutally_ hard. (* Getting 50% means you passed the subject and so you wouldn't have to repeat it next year.)

I just had a thermo exam. It was a 24-hr take-home exam (We were already gonna get a take-home before COVID-19 happened). Our professor warned us at the beginning of the semester that, on his take-home exams, he reserves the right to ask *anything* within the scope of the course that we've covered. So I get the exam yesterday. There's 5 problems. Surprisingly, the majority of them weren't so bad - heat engines, Helmholtz/Gibbs free energies, Maxwell distributions, Boltzman factors and partition functions. Nothing terrible. There was *one* problem though on the van der Waals equation with three parts, and oh my god it was a mistake to leave that one for last. The part in your video with "I can't do part (a), so let me move on to part (b)...Oh, use your answer in part (a)..." described my experience with that problem to a T. Couldn't do part (a), moved on to part (b) which needed the answer from part (a). Put down what I would do if I had the answer. Moved on to part (c), required the answer from part (b). And it just abstracted further and further from any meaningful answer from there.
me EVERY time, despite the fact we're typically allowed a formula sheet! i always forget a formula that I have spent some portion of the test rederiving lol
integrate "a = a" with respect to time, twice v = at + u s = 1/2 at^2 + ut (+ s0) then t = (v-u)/a => s = 1/2 (v^2 - 2vu + u^2)/a + uv - u^2 => 2as = v^2 + u^2 - 2u^2 + 2uv - 2uv v^2 + u^2 = 2as
We know all know that feeling of having spent 20 minutes on one of your questions only to conclude it has to be wrong… and then move on to the next one
I once had a very long math problem where I was supposed to prove something, and I noticed one mistake at the beginning of that proof when there was like 10 minutes left of that exam. I had to hurry and make a ton of corrections throughout the entire proof, and I just barely made it, and passed that exam largely thanks to that.
Reminds me of that dreadful first ever test of Physics I took...only six questions with multiple parts and it totally annihilated my trust and confidence in this subject 😭😂😂😂😂 That was years ago..but the trauma is still fresh!!!!!
@@josue_mejia It's much faster to keep everything as variables. Compare writing a single letter to a string of digits. The numbers themselves don't actually convey any conceptual information, so you need to rely on your short-term memory and units to track what's happening. Compare that to solving symbolically, where you can take any equation in a solution and you'll be able to see what's going on: oh, they're manipulating the electric field, distance, and charge: E, r, q.

Rewriting much of our current understanding of the universe and laws in which we all operate. Or… I have made a colossal mistake somewhere buried beneath 3 pages of math.”

1+1=2. Explain why this statement is incorrect and thus solve it correctly. (10 million marks)
It's Binary. The correct answer is 10
I usually transpose the one to the other side using algebra therefore I get 1= -1 instead of 2
It's Boolean. The correct answer is 1.
Let a=b
So,
a=b -----(1)
Multiply a both sides
a² = ab
Subtract b² both sides
a²-b² = ab - b²
Because a²-b² = (a+b)(a-b)
(a-b)(a+b) = ab - b²
Taking b common on RHS
(a-b)(a+b) = b(a-b)
Divide both sides by (a-b)
a+b = b
From (1)
b+b = b
2b = b
Divide both sides by b
2 = 1
1 = 2
Adding 1 both sides
1+1 = 2+1
1+1 = 3
Hence proved

Use your results in quantum mechanics and general relativity to solve for a unified theory
Physics in a nutshell
Use your knowledge in Newtonian mechanics to answer the following questions:
1. What was before big bang?
2. What's dark matter and how is it related to the meaning of life?
@@baab4229
First, I know you're joking ok? I just want to answer something anyway, lol.
1- How much time before the Big Bang? I mean you could literally say 'singularity" and that wouldn't be wrong because that's what existed before the actual expansion, right?
2- listen fam, Dark matter is something we can't see but we know It's there because of how It interacts with the formation and rotation speed of most galaxies. Also, It doesn't have anything to do with the meaning of life, unless you set something related to Dark matter as the ultimate goal in your life, since the meaning of our lives is whatever we want It to be.
Not a physics major, so sry for any dumb shit I might have written.
Milton Marques for part 1, you’re right that there is a singularity. But there is no time time before the Big Bang. Therefore, nothing can happen ‘before’ the first moment in the universe
@@bobross5716 But how do you know the Big Bang was the first moment of the universe? Isn't it a model of how the universe became what It is today rather then an origin explanation?
@@Haki145 It is a model that is about as close as you can get to an origin. When everything was a part of the singularity, everything was at one singular position at the origin (sort of x=0, if you want to think about it that way). Since according general relativity, space and time are one and the same, this means time was also at its origin. If "space is equal to zero" here, what that really means is space-time is equal to zero (although GR breaks down at the very first moments of the universe, so who knows maybe it is wrong). If that's the first moment in space-time, there cannot be a moment before it. That's how I understand it anyway. Whether or not there was really something before that (multiverse, big-bang big-crunch cycle, etc...) is outside my realm of knowledge.

In my second year undergraduate physics degree in the E-M course everyone was getting like 30% scores on the assignments and were taking like 4-6 hours each week (we had maybe like 8 or 10 concurrent courses) and the lecturer took time out of one of his lectures to explain that the problems took him 40 minutes to do so we should easily get them done in an hour.

THIS IS TOO ACCURATE
In all my years of learning physics,I'm proud to announce that I've never gotten a negative value for time
I just gave up midway
It is perfectly possible to get both positive and negative values for time (I'm talking about high school physics lol) when the quadratic formula is used. Of course, the negative value isn't included in the answer.
(Correct me if I'm wrong haha)

I love the way we had to derive formulas that we'd never seen before. When we'd ask the professor what was expected, the answer was invariably, "It should have been obvious."
I remember in my first year physics paper we had a series of questions asking for calculations when there aren’t a single number given to us. Still haunts me this day

*_I'm about to end this girl's whole career_*
false.
when my friends/professors ask how the exam was, I start tearing up and give them the “does this look like a face of a person who did well?” look
I just had a thermo exam. It was a 24-hr take-home exam (We were already gonna get a take-home before COVID-19 happened).
Our professor warned us at the beginning of the semester that, on his take-home exams, he reserves the right to ask *anything* within the scope of the course that we've covered.
So I get the exam yesterday. There's 5 problems. Surprisingly, the majority of them weren't so bad - heat engines, Helmholtz/Gibbs free energies, Maxwell distributions, Boltzman factors and partition functions. Nothing terrible.
There was *one* problem though on the van der Waals equation with three parts, and oh my god it was a mistake to leave that one for last. The part in your video with "I can't do part (a), so let me move on to part (b)...Oh, use your answer in part (a)..." described my experience with that problem to a T. Couldn't do part (a), moved on to part (b) which needed the answer from part (a). Put down what I would do if I had the answer. Moved on to part (c), required the answer from part (b). And it just abstracted further and further from any meaningful answer from there.
My favourite trick is deriving equations in an exam from dimensional analysis
me EVERY time, despite the fact we're typically allowed a formula sheet! i always forget a formula that I have spent some portion of the test rederiving lol
How can you derive equations using dimensional analysis? That makes no sense. Dimensional analysis is basically converting units to units.
What was the equation for acceleration again? Whatever I just derive it and waste half my available time
integrate "a = a" with respect to time, twice
v = at + u
s = 1/2 at^2 + ut (+ s0)
then t = (v-u)/a => s = 1/2 (v^2 - 2vu + u^2)/a + uv - u^2
=> 2as = v^2 + u^2 - 2u^2 + 2uv - 2uv
v^2 + u^2 = 2as

We know all know that feeling of having spent 20 minutes on one of your questions only to conclude it has to be wrong… and then move on to the next one
ive made a rule for myself that after like 5 minutes (depending on how long it is) i cant figure out how to start the question, just move on lol
I once had a very long math problem where I was supposed to prove something, and I noticed one mistake at the beginning of that proof when there was like 10 minutes left of that exam.
I had to hurry and make a ton of corrections throughout the entire proof, and I just barely made it, and passed that exam largely thanks to that.

In my physics 2 class everything it's in terms of variables at the end.
@@josue_mejia It's much faster to keep everything as variables. Compare writing a single letter to a string of digits. The numbers themselves don't actually convey any conceptual information, so you need to rely on your short-term memory and units to track what's happening.
Compare that to solving symbolically, where you can take any equation in a solution and you'll be able to see what's going on: oh, they're manipulating the electric field, distance, and charge: E, r, q.
@@jamieg2427 No, I mean...
