Every force has an equal and opposite force, so when you jump, the same force does, in fact, apply to earth. But the Earth is so large that the force applied from the jump is nowhere near enough to move the earth any measurable amount.

Reply to comment by MidnightAdventurer in Eli5 why does a survey need to have a minimum of 30 respondees to be statistically significant? by shashwathj
Fair enough. We would have to look at the many, many other studies that have already been done that prove America is truly a fascist state.

There is no set minimum to be a valid sample. What matters is confidence intervals. Confidence intervals basically mean 'how much of the sample needs to align for it to be significant.'
Imagine you only asked 2 people if America is fascist, and they both said yes. Does this mean everyone thinks America is fascist, or is it just random? You have no confidence.
If you ask 30 people, "is America fascist," and 28 say yes, you can be 95% confident America is fascist.
The larger your sample, the smaller % you need to gain confidence. If you asked 1000 people, and 700 say yes, you can still be pretty confident that America is, in fact, fascist.

Reply to How did you go about home ownership in NJ? by sufinomo
I took a 15 week course on responsible home ownership, and the county gave me 10k.
I then bought a condo for 65k in 2012 using that money as the down payment.
I sold the condo for 95k in 2019 and used the profits for the down-payment on a larger single family home.

Reply to eli5 Interest is confusing by maddskate
Interest is just the cost of borrowing. If you ask to borrow 10 bucks, I might ask you to pay me back 11. That $1 is the interest.
Interest is usually expressed in annual percentages, like 20% a year. So if you borrow $100, in 1 year you would owe $120. After another year it would be $120*1.2 again, or $144.
But then it gets more complicated, when you factor in compounding. Compounding refers to how many times the interest is calculated. Is it 20% 1 time per year? Or is it 20%/12 each month? Or maybe it's 20%/52 every week. As it turns out, the more times you compound the interest, the more interest you will end up owing annually. So this is an important factor. (Most loans are monthly)

My home shower has a thermometer too, and 38 is too chilly. Give me 40-42 any day.

Reply to ELI5 what is dy/dx? by EarlaSallow
It's read as "the change in y with respect to the change in x". Basically, it's asking you how changes in x affect y.
If I asked you how volume changes with respect to pressure, you could graph that out. If I asked you how volume changes with respect to color, the graph would look very different - it doesn't. It's important to specify the respected property so you know which graph to draw.

At those numbers, paying it off only saves you about $100/yr (give or take). If debt to income ratio can handle it, you're probably better off putting that money towards the down payment.

Reply to My Thoughts on Zodiac (2007)… by Standard_Rip9349
Amazing movie. One thing worth knowing tho, is it takes a very biased approach to the facts of the case. Experts don't even consider Allen a top suspect and the movie leaves out details that create doubt. The movie also completely ignores other top suspects, because it doesn't want you having any conclusion other then Allen did it.
This doesn't make it a bad movie, it's just important to remember that it's Hollywood.

Reply to comment by defalt86 in ELI5 Why when we jump in the air the earth doesnt move by Alternative_Bar_6441
Another fun answer is that motion is relative to your frame of reference. From the jumper's perspective, the Earth DOES move and its the jumper that remains still. Scientifically, both points of view are valid.
