Anyone good with Physics?

Can anyone explain Hubbert's Peak to me? I have an exam tomorrow and I was absent the day we learned it and when we did the homework example.

We were calculating how much oil we've used up till now and how much we had left tp utilise. it's a bell curve but how do you make it? ARRGH!!!

I don't have a fucking clue mate, but that post is a crack up.

With a pencil and a piece of graph paper? Or are you artistically challenged?

Here's a good article, with some mathematics to generate the curve:

Article.

It's the shape of a bell curve but the problem is I don't know what size to make it.

Art doesn't challenge me, I challenge art.

I already took the test, and in all honesty, had no idea how to calculate and sketch the hubbert's peak. Like I said, it was a homework I missed, so I read a bunch of chapters in our book, wasn't there, I looked online on maybe six sites, including a really abstract math webpage, which I thought was it but I was wrong.

I should have just asked the teacher. And right now, I still have no clue how to do it and extremely mad, and for the time being, I hate myself. Does anyone here know how to predict oil shortage on graph paper? Total world supply is hypothetically 40 billion barrels, calculate on graph paper when the oil production rate will drop to...3.5 Gbbl? I don't have it in front of me but i think that's the number.

From the wikipedia article, it looks like the equations are all there for you to calculate it. I'm sure the test would have supplied the constants for you in the process.

If the test wanted a graphical answer, then I would assume that the curve was supplied to you. In that case, just find the number of barrels of oil and locate on the graph the corresponding time. This is, of course, if you can define/identify 'oil shortage' with respect to the question.

Wikipedia is only helpful 1/2 the time, usually in a foreign language and I have to draw the curve, so no, it's not supplied to me. It said each big square on the graph paper was 1 Gbbl and it started off the curve, maybe 1/4 of the curve with points. It also has a y axis for annual production and an x axis for the years, but on the y axis, the numbers only go up to 10 Gbbl, so how am I supposed to graph 40? Maybe that would mean the peak is 20? That still doesn't fit.

I have the homework, warning I totally messed it up, but you can still see everything. I BSed the curves and drew the line where I thought it should go. I hereby state I think my answer is BS. EDIT-did not hand this in.

Next time I'll use pencil, scouts honor. ,,\/

Hmm... what confuses me is that part a) explicitly states that there is a curve/plot given. Also, the 40 is total thus it would be the area under the curve as stated in the problem (think calculus integration and not the peak of the curve.) Either way, you've got me. Sorry, I tried.

Does the problem have anything to do with statistics? From what I gather, it looks like you could use a normal distribution bell curve to help answer this question. http://en.wikipedia.org/wiki/Image:S...on_diagram.svg

But then again, its been a long while since I was last in college and I've never seen this type of problem. What type of physics is this? Major?

It is using statistics, but I thought there was a slope you need to know. Mainly, I don't understand how 40 squares fits on here, let alone 50. I've seen other people draw it and I don't know how they came to their answer either.

It's Environmental Physics, a class that didn't require a prerequisite. My major is computer science but I'm taking physics because I really like the material.
