Khan Academy. My friend showed it to me senior year. It's a great video website for learning various elementary to college level topics. The instructor and creator of the videos is just an amazing teacher.
From what you have writtten above it is quite clear that you are not "retarded". You seem to be quite able to express yourself and, if fact, do so in a clear and concise manner. Don't be so hard on yourself.
Have you been tested for any learning disabilities that may effect your ability to do well in tests? If you have and are all clear then it could just be the case that you need a different teacher. Have you tried looking online for learning opportunities such as with Khan Academy? You may just need to find a teaching style that works for you.
The mother site contains over 2000 short, 2 minute videos on various topics. The Site listed includes 15 or so that explain the underpinings of the financial crisis including mortgage backed securities, credit default swaps, etc., These videos are informative, and the information is easy to digest.
By making it boring via tedious, rote work. By failing to point out the magic. By not making it clear how such things will be useful down the road. Story problems are generally situations no one is ever actually in. I have never had 25 apples and had to distribute them among three friends.
If classes were more integrated and some more practical things were taught sooner—simple programming and engineering and scientific experimentation—which made use of various mathematical techniques recently learned in another class, I think students might actually be more engaged.
Additionally, I'm not sure what exactly it is that makes it different from regular classroom learning, but the videos on the Khan Academy are extremely engaging and can, over just a short series of 10 minute videos, teach concepts that take years to learn in schools.
Higher Education: The next bubble to burst. It simply can't continue on the path it's on now.
I like what the Khan Acadamy is doing. The evolution of this will be the future of the educational system.
We should be teaching our kids to be autodidacts and getting their own education.
Check out Khan Academy. All of their learning tools are free and you can find practically anything you would like. iPod-U also has some great learning tools, but I seem to remember most of them being at university level.
You may also want to speak with your local librarian about a literacy coach. There are volunteers who will help you with your reading level if that's something you're uncomfortable with. You may also want to check your local university about adult learning courses. They will teach you study skills, and will enroll you at the level (finite, pre-algbra) you're currently at so that you're successful over the course of your academic career.
Learn something that you've always wanted to. It doesn't necessary have to be academic, it can be anything you're curious about. You'll meet people with like interests along the way.
I taught my daughter calculus starting around age 6-7. Actually Salman Khan did most of the work. She's now 10 and knows most of the math that I do and then a bit.
All the rest of you with school age kids, start them on Khan academy! If you don't know the material, learn it yourself. It's not really that hard, and it's shameful how much public schools have dumbed down math education.
I used to have this problem...
I spent a lot of time at school / uni / work not being great at maths. I used to understand the concepts of algebra and pre-calc etc at a high level but really couldn't apply it. It just didn't make sense to me.
The turning point came when someone (my wife) pointed out that I seemed to be missing some of the fundamental experience with the basics of maths. Stuff that I felt I should just know. I was actually oddly unable to even admit to myself that i really didn't know some of the stuff that (in my mind at least) was trivial.
The way I solved this was to go right back to the beginning - learning very basic fractional manipulation, really simple algebra from simple linear equations, on to simultaneous equations, to quadratics and pre calc.
This was an eye-opener for me as once I started laying solid foundations to my understanding it was so much easier to build on.
Later in life I went on to study for an undergraduate degree in Maths. Something I'd never have done without someone pointing out to me that you can't build a house without good foundations.
Try this out [link] There's a Math(s) section and it's very good.
TL;DR: If you're struggling maybe you need to go right back to basics and build up your understanding. It worked for me.
Right after submitting my entry i also learned that I could've just linked the actual friggin site instead of the wiki article I was reading >.<
Edit: wtf, I can't believe that searching for the original Khan academy URL would take me to the University of Reddit which I've linked. That clearly needs to be regurgitated on the front page more often!
If you're serious, you might wanna know about Khan Academy. I sucked ass as math, but nowadays (and 50+ videos further) I don't suck as much anymore :D
Note: the website ~~needs~~ requires a Google or a Facebook account to log in to.
edit 3: You'll need to log in when you want to practice! It is acutally not required when you want to watch videos!
Khan Academy is wonderful. Start from the basics, though, even if you think you're good. Mathematics builds upon itself, and without a proper foundation you can't really progress.
And this is why the Kahn Academy model is so sorely needed to educate the future.
I hated school because I was bored, and also one of the reasons why I did not do well. The main one being I was lazy.
Look up the Khan Academy. Its a free online college level education with hundreds of videos on many subjects. There are 63 biology videos, each is about 20-30 minutes and explained very well. I homeschool but everyone in my family is an atheist. I take many Khan academy courses as a part of my education and I recommend you do to.
Heres a link [link]
I know you're kidding but maybe we could all use a little bit more of the r/universityofreddit and Khan Academy-ies of the world and a little less of r/pics
> I genuinely wish I understood more about the bailout, though. It was one hell of an economic event.
Here's a series of 15 videos from the Khan academy that break it down for you in detail like you're five. :-)
Khan Academy may not exactly be deemed all interactive but it has a huge amount of videos available and quite a number of interactive mathematics practice, so it is well worth your time if you want to learn science and maths stuff.
MIT has free online courses for CS, Khan Academy has many helpful Math and Logic lessons, all of which are free, and here are a ton of free online CS textbooks.
Did I mention all of those are free? You no longer have any excuses. God speed, my friend.
you may find help here in this massive amount of free instructional video published at Khan Academy
>Topics covered in the first two or three semesters of college calculus. Everything from limits to derivatives to integrals to vector calculus. Should understand the topics in the pre-calculus playlist first (the limit videos are in both playlists)
Get a few garbage bags and throw out everything you don't need in that computer room. Make it look tidy, at least briefly, like it was being shown to sell.
Get out of the house. Walking is a form of exercise. You can lose weight that way. Don't put crap in your body - especially when weight loss is a major goal.
Figure out what is at khanacademy.org. Make your self spend 1 hour a day there. Set up an account and start at the beginning.
You can learn useful overviews of topics and history over at wikipedia. Focus on school topics. Get some knowledge in your head.
Schedule your time. By 9am, eat breakfast, shower, get dressed and do something for exercise. Late morning, early afternoon, learning. Don't waste your time; actually learn something. Finally, after supper - you're done. It's you time. If you didn't get enough done, work harder tomorrow at getting it done during the day. Don't spread the misery out.
Eventually you want to get yourself into an adult education class. Lots of people do this. This up coming week find out where you will eventually go to do this in your city.
Once you're in a better place, get a part time job. So what if it pays minimum wage.
Remember: You want to be a more reasonable weight (diet + exercise) and more educated (useful time on specific websites + adult education). The mess you're in didn't happen over night and will take time to turn around. Don't dwell on the past -- work on getting to a better place.
I don't who you're living with, but consider letting them in on your plan. Let them know that you're working towards improving yourself.
Recap: Clean up your office and bedroom well. Stop drinking sugary coke. Stop eating poorly. Walk; exercise. Focus of learning. Don't sabotage your life.
I'm truly sorry. You have been cheated of your right to an education by scoundrels.

This should be useful also: [link]
This one should help with your first question.
And this one should help with the second.
I could never have gotten through it by myself. I recommend to seek out groups to study with, going to office hours (write down questions during class on everything you don't understand if it's a large class and you can't ask during), people who have taken the class before / tutors, and check out websites like these:
Depending on the area of ECE you go into, it can become less math and physics oriented. Depending on courseload, I would recommend not working part time, but don't study constantly. Take breaks and have fun: your mind will work towards figuring things out even while you're not actively studying.
ECE isn't for everyone, but if it's your passion, don't give up yet.
Khan Academy explanation of Compound Interest:
Here's a great resource for secular homeschoolers:
Right now it's still math-oriented in its exercises (that's not a bad thing but I'd like more), but there are a lot of videos on a lot of subjects that are good watching.
Don't worry, it's a pretty simple concept. Basically, the adenosine group is linked to three phosphate groups in a chain, an arrangement that causes the third phosphate group to exist in a high energy state. Thus, the detachment of the third phosphate group results in a release of energy that can then be harnessed for other processes. You end up with ADP (adenosine diphosphate, intuitively) and a 'free-floating' phosphate group, which can be united again to transport more energy (the basic idea behind the cellular respiration and light-dependent reactions of photosynthesis). At least, that's my understanding. I'm not a biologist, just a high school student with a strong interest in the subject.
This video from Khan Academy explains it really well.
There are many like you, and always, the Khan Academy is brought up. If you haven't checked it out, I would start there.
If you insist on getting a book, I really have no idea what to recommend you. Sorry.
Not to discourage other redditors from putting a class together on this, but have you considered using Khan Academy? Sal's an excellent instructor and you're able to practice your newfound skills in various problem sets. There's even achievements!
Oxford History of the French Revolution by William Doyle
Khan Academy has a bunch of great video lectures about the French Revolution and Napoleon
Thanks. I love stuff like this and these guys do a lot of kinesiology and exercise science-which is good! If anyone want more free education, particularly in math and science, check out Khan Academy. Also, hook me up with any other websites you may find that are similar.
Lots of truth in that - I sucked at maths in high school whereas I'm a straight high distinction student now. (Those are A's for you Americans).
At the start of last year one of my lecturers said maths is easy - and somehow it just sunk in that it is.
I think in many ways the reason that I struggled in high school was not being taught the whole of a method, or at least enough that you can understand its properties.
Maths is a subject you can get great grades in just through practice. It now seems easier to me than writing creatively for instance.
So in essence, just keep at it. If you are struggling watch some lectures on youtube or through khan academy.
I'd just like to point out this phenomenon isn't US specific. It happens here in Finland even though we're said to have some of the best (mathematics) teachers in the world. (This is according to PISA studies.)
What I've learned to do is look up all the things I'm expected to learn at Khan Academy. They don't have anything on local diffeomorphisms, but everything up to that point I've found a clear explanation to!
Good for you! I hope that the love keeps flowing, but there are times when things mighty get sticky. When that happens, don't forget all the places you can go for help like r/cheatatmathhomework, The Kahn Academy, Ask Dr. Math, your campus tutoring center, etc.
If you want to improve your intelligence, you can use websites like MIT open courseware and [link] to improve anything you wish, if you are willing to watch the lessons and do examples.
I'm going to use a sports analogy (this is ELI5 after all)
Red Team (Republicans) and Blue Team (Democrats) choose who they want their captain to be with primaries and caucuses. In primaries and caucuses, the team mates vote. In a closed primary, you can only vote for team mates to be the captain of their team. In an open primary, you can vote for the other team's captains. A caucus is a little more complex (watch the aforelinked video).
After each state votes, they win delegates, which are people who pledge to vote for a candidate. The delegates then go to each team's meeting (Republicans: RNC, Democrats: DNC) and put in their vote, representing the rest of the team's wishes. Depending on how that vote goes (we usually know the result before they actually go to their meetings to vote), the person that they ultimately choose to lead their team is put on the ballot so that anyone (on the Blue Team, Red Team, or other smaller teams) can vote for him to win.
OP's question is like asking, "What if Blue Team people go on Red Team so that they can vote for a bad captain that would make it easier for Blue Team to win?"
He prefers to keep his religion a private matter, and on the website it says:
"If you believe in trying to make the best of the finite number of years we have on this planet (while not making it any worse for anyone else), think that pride and self-righteousness are the cause of most conflict and negativity, and are humbled by the vastness and mystery of the Universe, then I'm the same religion as you. "
What we can safely say is that there's a decent chance he has been influenced by Islam(as many of his relatives are Muslim. That said, it's relevant to note that historically Muslims connected the ancient Greek un-translated works with Renaissance Europe, so we don't think that somehow being religious is being anti-science.... ).
I strongly recommend reading Darwin's On the Origin of Species. I know it doesn't sound original, but there's a reason it made a stir! Clear, simple thinking. You can memorize a lot of facts, but to understand the underlying forces and reasons that explain why those facts align in the way they do - you'll need to understand evolution. And it's not really that complex.
Also, Khan Academy.
^-- I cannot recommend this strongly enough. Free videos that go through pretty much everything you'll need to know in a first-year biology course at college.
And just for fun: the video that jumpstarted my love for molecular biology. Watch this, and don't worry that you don't understand most of what you're watching. It's all of the little molecular biological interactions that made the original scene possible: movement of a white blood cell through the veins, eventually slipping between two cells in the wall. Beauty. Pattern. As you learn later, you'll enjoy coming back and watching and saying, "Aha! I know what happened there!" Have fun with your studies kelsbar. Welcome to the world of biology.
Watch this and the following videos: [link]
It takes him a few videos to start explaining the China situation, but you need the background to understand what's going on.
If you are studying for the GED and need help with the math portion, try using Khan Academy, if you don't already.
Sorry for the unsolicited advice. Hope you aren't offended. Good luck!
Khan Academy is without a doubt the website you want to use.
It goes thru alot of maths and even economic ideas, that will definitely help you start. you can even login in and track which videos you have reviewed and track your progress
I'd start with these: Khan Academy - Biology and work your way into the Chemistry and Organic Chemistry sections.
I'll post them here for accessibility/historical.
Every item on the list is a direct link to Khan.
Side note-- It's worthwhile to mention Khan also has a large focus on python lessons
Some of the topics in Introduction to Artificial Intelligence will build on probability theory and linear algebra. To brush up, here are some related videos from Khan Academy. Watching these videos is not required, and you can probably do well in the class even if you are not initially familiar with these topics but are willing to work hard.
Linear Algebra Prerequisites
The community college stuff is a great idea. I'll just add that, while waiting to do that, you may want to buff up on some remedial stuff (chem, bio, algebra, trig, maybe calc, etc.) with the Khan Academy.
I'm going to side track this discussion in a positive way i hope! With things like [link] , people can be in charge of educating themselves. MIT is offering free online courses, and it's really the cheapest way of educating the masses.
He's on point about making sure you educate yourself on all aspects of a business, but if you don't want the hassle of an entire degree program just take some classes you think would be useful to you (business, math, basic accounting). There's also many great books and online resources if all you need to do is learn the material (Khan Academy, MIT Open Courseware)
Also, try and learn what you can from your boss (if you like the way he/she does things) or find another contractor you respect and learn from him/her. Mentors are a valuable resource. People have become contractors in the past and done it successfully with less information resources than you have now, you can do it! Best of luck.
I've already seen the answers posted but I wanted to post these Khan Academy videos that I found helpful when learning about this topic.
This is about calculating stellar distance using parallax.
And this one explains red and blue shifts.
I could write a long block comment but I feel Sal at Khan Academy does a better job of explaining than I can, also you might find some other cool cosmology/astrology videos you want to watch.
Have you ever heard of Khan Academy? I watched a video about a class room were the children spent all in-class time doing homework with the teacher, and their homework was watching videos from the site of their choosing.
and I don't care what #'s your professor assigns. Do all the problems for a given chapter, unless its like completely irrelevant shit ( to the course ). Understanding electron movement is worth 10x more then memorizing mechanisms.
Practice drawing hexagons in all your other classes.
I don't know if you're aware of the Khan Academy, but Khan's videos are an immense help when you're puzzling out new math topics. I highly recommend watching some of his vids.
Khan Academy explains this very well in a Currency Exchange lesson, available here.
Now, this video is if you want to learn about currency trading but it also shows you how the values of currencies change very well.
If your goal is to get into machine learning, linear algebra is going to be your best friend. There are structures like vectors and matrices that are elemental to the understanding of large scale data and data manipulation. Check out the Khan Academy to get grounded in the basics.
In general the more math and stats literate you become, the better off you'll be. MIT, Yale, Stanford and several other schools offer their courses online for free. I think Khan is the place to start because that was designed to be used by people on the internet who are learning the basics (i.e. you).
After that you will need to bone up on your programming skills. I like Python and R, both are free and have plenty of resources to help those who are new to the field. The Stanford online course in machine learning uses Octive, which is a development language for machine learning, but I don't know that much about it.
tl:dr Attend to your math first, then learning to program. You'll need a semesters worth of linear algebra (minimum).
Khan Academy is great IMO and has a cool exercise dashboard here which is a visual map of topics starting from basic addition all the way to some calculus. I'd suggest starting with the Addition 1 exercises. They go very quickly at first and it will help you brush up on the basic skills.
Here's a similar thread posted here about a week ago with more comments and some of the same info I've given you above.
Check out some of the other math subreddits linked to on the sidebar here too like r/learnmath.
I'm in the boat as you except I have done some calculus and calculus-based physics before. Good luck!
I would love to help but there is no way to do what you are asking, Options are not simple and take time and effort to learn and truly understand.
Have you watched the Khan Academy videos? I think they are pretty clear in their explanation.
Call Option - Put Option
Another place to get good information is the CBOE. Here is their basic option tutorial.
If you still don't get it, maybe try asking a more specific question.
Google says that was actually a serious answer? The internet is weird.
Also, for the lazy, or those who, like me, hadn't seen that one before - [link] (but feel free to let lnxaddct have the upvotes.)
Learning. It does cost money indirectly, but if you're reading this, you already have all the tools you need to learn a whole lot of things. A new language, how to program, mathematics, physics, chemistry... if you know where to look, you can find excellent quality material intended or suitable for self-instruction on just about any topic.
First, congratulations on deciding to further your knowledge of basic math, you might decide to check out Khan Academy as you get to other subjects that you might have previously had trouble with. The answer to your question is that you have a "remainder" of 4. That means that 12/8 is actually equal to 1 + (4/8), or 1 plus 4 over the original denominator. That's why the calculator gives you .5 , you don't just put the remainder after the decimal point, you put it over what was originally on bottom to find the decimal.
I know it is in the sidebar, but I am just going to plug KhanAcademy.org again. Seriously, if you are struggling in calculus or other basic undergrad courses(chemistry/physics) this is such a wonderful resource. If you take time with these videos I am certain you can get an A in any of the subjects that he fully covers while gaining a better understanding than you do in a bland classroom. Another useful useful source for math is www.patrickjmt.com
Better luck next time around.
As he said, Cells that replicate often are the most likely, because each time a cell divides, it gives it a chance to cause a mutation that beings the waterfall effect called cancer. An example of a highly reproductive cell structure would be the lining in your colon, which replicate on a monthly basis (If I remember correctly). An example of the opposite would be in the heart, where cells take much longer to replicate, which is why Heart Cancer is a much rarer form.
Khan Academy has a great 4 part video on colon cancer that can help answer many questions that you may have on the spreading of cancer.
Watch this first, then the next 3, and you will see a much more detailed explaination.
Don't forget about Khan Academy. I've watched both, both are great. Khan Academy is little less formal and it's a purely a lecture. Depends on what you prefer!
I haven't specifically seen these videos but Khan Academy is usually a great place to start learning something. The videos are free and usually easy to understand.
The Khan Academy has a history section, with a few vids giving a general perspective on US specific history.
Start out with khan academy [link], I honestly havent watched the physics videos as Im currently using the site just to learn linear algebra but judging on how well he simplifys concepts in maths, I assume to does an equal job for physics. Learning physics early on is also fairly non linear so you can take a subject in it your interested in and start with that.
[link] is also a nice reference
Bookwise something short enough, fairly comprehensive and fairly easy is six easy pieces, its a compilation of some of the feynman lectures on physics and is a very good introduction to alot of the main concepts of physics, although slightly outdated towards the end
Pauls Online Math Notes, aka the greatest math site you can go to for step by step explanation. For videos khanacademy, or this guy cover pretty much any math related subject you will ever do.
I'm sure you're familiar with the Khan Academy. These videos "roughly cover a first-year high school or college course".
Just take a look at the titles and ask yourself how much of this stuff you can learn by experimenting with a high school level chemistry lab. If you want to do things hands on, sure, that's fine. But don't fool yourself into thinking you're going to get a "comprehensive understanding" of the subject. Sooner or later, you're going to have to read a book.
Math scared the crap out of me too, but I loved CS and decided to give it a shot. Made it out OK. A BS comp sci degree isn't quite as math heavy as you might think.
As for the rest... recently I found out about Khan Academy, and I'm trying to use it to recover from my terrible high school math education.
This is attitude is not limited to disposition towards homeless people, its a by-product of our evolution, arrogant and aggressive males get to breed with women more often than quiet, intelligent men with less confidence and aggressiveness, as a result more aggressive and stupid people make up the general population.
Not something you can do much about because women favour the alpha type, as long as that trait is the successful trait people will keep passing on these negative traits, scientific studies have already proven that behavioural traits are passed on through breeding, its how we have domesticated animals.
If you had a number of women with a choice between a male who is an intelligent, very agreeable to her, in general very pacifist like and peaceful and a male who is aggressive, stupid, arrogant, daring and generally more primal/primitive in his ways the woman will usually pick the latter, its how the nice guy argument comes up.
This shit is happening all the time and it will keep happening until we end up with a very aggressive, uncaring and stupid human population.
This is relevant, watch it
Useful for a variety of sciences and it has quite a good series covering chemistry. I'm self taught with no post secondary experience and have managed to obtain at least an adequate understanding of the chemistry material.
Study up on your calculus first - it's important to have a very clear understanding of it. Your class textbook should be adequate to begin with, but I would recommend simply watching videos on the concepts rather than committing yourself to the early study of a textbook.
Physclips is a useful resource made by my own uni's first year lecturer. He gives fairly useful and upbeat explanations, and I believe you would get a good overview of standard first year topics.
Of course, as well as (or instead of) Physclips, Khan Academy is always worth checking out. He has a lot of videos on Physics and you can trust that you'll be getting excellent explanations if you go there.
Just on the off-chance that someone actually wants to know what purpose the Fed actually serves, and wants to step out of the bubble of /r/politics. Khan Academy (a site started by a couple of MIT graduates) has a really good explanation of why it is important.
How to become a good theoretical physicist (very important)

It had little to do with their spending. I suggest you educate yourself on the underlying causes of the banking crisis.
I'm Tiza (same IGN), I've played ~200 ranked games and ~1100 normal games. I'm currently ~1300 Elo (apologies for the fudging, I don't know off the top of my head). I have extensive competitive experience in other games and sports, as well as teaching experience, and I'm an active contributor to r/SummonerSchool. I'm trying to give back to the community to help the whole community grow smarter and stronger together.
There's a lot of things to know about LoL, and a lot of things that are easier taught than learned (as opposed to mechanics, which need to be learned). I'm trying to help players learn as much as they can the easy way, so they can focus on the stuff that can only be learned the hard way. My long-term goal is to create the Khan Academy of LoL - a place to guide low-to-mid-level players intuitively and comprehensively, instead of throwing them wordy, poorly-laid out single-champion guides or under-explained streams. =)
Don't worry about the lack of formal education, something like 60% of kids today move back home. Student loans are the next bubble in America, after that higher education will never be the same.
Bill Gates says that in a few years, no one will ever need to pay for college again.
Try the excellent 'Khan Academy'. It has many youtube videos of various math concepts explained.
There is also a 'fun' workplan geared towards kids:
Please let us know how you find it. It's got many recommendations on here.
Khan Academy has a lot of material on trig, usually very well explained. Maybe start here. Or are you looking for somethng else?
Khan Academy and good study habits.
Then major in physics.
Obligatory Khan Academy recommendation. He should have some videos on any topics you need to brush up on :)
Edit: the trigonometry and precalculus playlists in particular.
Take a look at Khan Academy – it's a completely free video library and the Salman Khan focuses a lot on understanding things intuitively in his math and science videos, which are the majority of the ones there. He can take you all the way from developmental math to multivariate calculus and differential equations while making things understandable and clear. I personally started learning calculus from the videos with significant success :)
I have never been able to learn math from a classroom. I never get the time or the attention needed to explain all the questions I might have as to why we do things the way we do. However I've started ignoring teachers and working with Khan Academy and I've gone from someone that struggles with basic pre-algebra to about half-way through Calculus.
You kind of have a private army of 20-30 year old Americans. I'm all good and signed up, and it sounds fun whatever it is.
Consider getting together with Salman Kahn. We MUST do something about the education situation in this country, and even better if we can help out the rest of the world, too. He has the math thing handled, you have the reading thing handled, but the good educators out there like you and him NEED to get together and get organized and fix this shit.
Edit: what I wrote before was stupid
I will tel you how to studied chemistry by myself.
I want to tell a story about myself. I was always lazy and unproductive all high school and early years of college. I didnt have any motivation to study or go to work. I learned a lot in life but I will try to tell you what I learned.
In order to have motivation, you need to have a goal. Something you want so bad that you will get up every morning, work your ass off. You would not care about eating, not care about hanging out with friends, you would give it all up to get what you want. In my early life, I did not experience this passion for something until I didnt get financial aid for my summer classes. I did not take enough credits during the fall and it would slow down my graduation a year if I dont take the summer class because its a prerequisite.
I knew I made a mistake, but I wanted to graduate and get a job so bad. I really hated my job at that time, it was like a jail that killing me slowly. I hated it so much that it gave me motivation to change! I will not make 8 dollars an hour, but I will make good money to make my parents proud no matter what.
I started working 56 hours a week for 2 weeks. Every morning when I woke up, I tell myself that I rather die then staying in bed and lose sight of my goal.
Well anyways, what I am trying to say is you need to have a goal you really want in order to be motivated.
I think learning things is the best thing you can do. Your knownledge will always be with you, it is better than having a new car or material things.
Writing this made me remember my old self. Xanax withdrawal had filled with anxieties and killed my motivation to study. I just remember what I want know. I will get As in my classes no matter what this summer.
Fuck drugs, it can control my feelings but only I can control my actions.
Finance major here - I don't understand what is shocking about this. He is basically saying that they will allow oil futures to trade as they currently do. Although there is a correlation between oil futures and gas prices - I would not concur that the two are directly causally related (especially when there is a decline in oil futures prices).
Secondly, saying that he is talking to "oil speculators" is a bit presumptuous. There are 3 types of futures investors - hedgers, speculators, and arbitragers. And there are also the people who use forwards as a way to lock in the price of their commodity to reduce risk (which is what he referred to in the video). If the argument here is that he is supporting "big business" and not "the people" then the majority of these people would likely be oil companies locking in their price for the future. There is nothing wrong with this - it helps them reduce risk - and a lot of big industries use this.
Here's a great khan academy video on the use of forwards to reduce risk: [link]
It helps keep the price of oil at a relatively stable level, and I would argue that without forwards that the price of oil would actually be quite a bit more volatile - and given that gas prices tend to be correlated, but sticky to higher levels, with a higher standard deviation of volatility this would be bad for the consumer if they were unable to do this.
I haven't used this site personally but have heard it touted extensively and I think it might help you a lot.
There is a physics section near the bottom if you scroll or F3 that might have what you are looking for.
Not sure why you think this would be a good substitute for an art history or philosophy degree. I think the point of getting a degree is just that, to be recognized academically. For personal use and knowledge I would agree it makes sense, but most people going for those degrees want to use them to do something professionally, even though they probably won't be able to get a job, or one that pays a living wage. Check out the Khan Academy too.
I cannot recommend this site enough!
It's all free. Thousands of easy to follow instructional videos on everything from basic math to advanced math, and tons of other subjects too! Scroll down to the section "Arithmetic" to catch up on multiplication, division, other basics, and then check out the algebra section too.
haha see that's why he asked about the significance level and the p value. In statistics you don't need a very large sample to know the population within a certain probability. Check it out [link]
mayne, investopedia puts ya off on da right foot, ma suggestion...read all da articles. den u can start readin da good shit lyke ma nigga buffets book. also dis nigga khan will teach ya a lot of gud shit. member ta read da wsj, bloomberg, ft, dealbook, marketwatch, ect. to know wuts goin on in da wild markets.
gud luck ma nigz, if ya need more pointers just let a nigga know
Khan Academy has a bunch of really good videos which will build a solid foundation of chemical knowledge. From there they offer organic chemistry videos as well.There is also MIT open courseware for more advanced courses. The sidebar has textbook recommendations for general chemistry and other topics as well as links to chemical forums where a bunch of knowledgeable people would be more that happy to direct you further and answer more specific questions.
Good luck, there is wide variety of topics in chemistry and it will probably take you a while to narrow down your interests. Keep exploring different avenues and attend chemistry research seminars given at your school if possible/available.
tbh, youtube is one of the best teachers for math. checkout Khan's Academy youtube channel.
This website has videos for everything. I used it all the time for differential equations.
Have you tried Khan Academy? The site has a section of videos for statistics . Let me know if those help you out!
PS: I know the guy has a tendency to repeat the same three words over and over as he's writing it down - I hope don't get hung up on it :P
Check out Khanacademy, it is nothing more than a really really smart guy and MS Paint explaining just about everything math and science related you can think of. Should you get hooked be prepared to stare at a computer screen for hours learning calc and trig... FOR FUN!!!!
I have found khan academy to be very useful for learning maths. It also has some other subjects, but it seems to be very maths heavy. I have heard lots of people who have struggled with maths, but have excelled by putting in time watching the videos there and doing the exercises.
Sal Khan is starting to show in the case of math (and this certainly might extend to other subjects) that the way learning works now, it needs work. :)
Right now, you learn a skill in math and then you are tested on it. You get 80%, that's considered a success. But there's 20% you don't have mastery over, but you move ahead anyway. This could be something crucial since everything new you learn in math is built on what you learned before.
What schools who are using Khan Academy have found is that there may be concepts that certain students (and not the same students all the time) may have trouble with, but once they nail that concept they often catch up and even jump ahead of the rest of the class. Then some kids who are ahead will get stuck on a concept, it will slow them down for a while, but as long as they are given time to master it they will come back and rejoin the group.
This is a fundamental change in how math is taught.
Sal Khan is really on to something with his Khan Academy, its not just a collection of videos.
So don't blame the "slow kid", blame the education system that is leaving him behind.
Here are some links to check out what Kahn Academy is doing:
Check this one especially to see how a pilot project in California schools is working out:
(I have no affiliation with Khan Academy, but I am inspired by what I see it accomplishing if it is embraced.)
Did you hear the guy, Salman Khan talk about his at TED?
Basically, he says we need to watch the best lecturers online at home after school, and then go to school and practice. Because: most teachers don't know stuff, or can't confer it to other as well as people like Khan!
Did you see in the sidebar "Other resources include: *Khan Academy"? There are also brightstorm and math.tv if you hate Sal's voice or something.
Each field of science will have it's own subset of heavily used equations and principles. If you're looking to "expand your knowledge" though, Khan Academy is a great place to learn the basics of each science field, from elementary/middle school up until sophomore/junior year of college level material:
Here is a link to the practice exercises portion of the site.
Here's a video explaining how the exercises work.
I know this is BS considering we are paying quite a lot for tuition, but you pretty much have to suck it up and deal with it.
I took Calc 1 last semester and I'll be taking the 2nd half this semester. Basically, I used Khan Academy and the text book/interwebs/wolfram (mainly for double checking solutions to certain things) to learn pretty much on my own. I personally learn better this way too and didn't even bother going to class for the last month or so (still ended up with a B+, and math isn't exactly my strongest subject), but not every one can do this, so YMMV.
Actually, the closest thing I could think of, as a free higher education, would be [link]
I mean, let's be honest, that's a real free college education. (or at least, an educational supplement)
This is a good place to start.
It really just takes time and practice. You have got to get your reps in. As in do a TON of problems in whatever area of mathematics you wish to get good at. Also, checking out this book might not be a bad idea. Lastly, teaching someone else always helps me tremendously.
I'm implying that the only thing brick and mortar schools have going for them these days is in person socialization - even then reddit proves it's possible to take another route.
[link] is the kind of model that might be actively pursued. Watch the TED talk - the idea is instructors help students only in the areas that they are struggling instead of standing up and lecturing them in a passive fashion.
I know several people who passed classes and obtained GEDs using just this site.
High technology and the internet are changing the way we do everything. At the beginning of my career in programming, I had to have a library of reference books to know how to do anything. These days I can find the answer to a problem I'm having in a couple of minutes, yet when I go to my brick and mortar school they'll still charge me $200 for books that I only use to get the homework problems out of them - otherwise they remain virtually untouched.
I know a lot of people use the internet for just dicking around and pr0n, but I cannot even begin to quantify how much educational material I've absorbed. The internet is worth much more to me than anything I have in my possession; it's even worth more to me than a college education from the best school in the country, as far as I'm concerned.
One of the few things I would value more would be the ability to stop time so I could absorb all of it.
