Looking for thoughts. I have recently gained an interest in Astrophysics and have considered going back to school to study the subject. I have a BS in Computer Science, and an MS in Information Technology and I believe my background is close enough to consider an MS program in Physics. However...

And I am not talking about celebrities such as someone like Stephen Hawking, who are famous scientists. I am talking about those that are people you'd never expect having an interest in mathematics, chemistry, physics, etc.

Hello, everyone. I've been trying for quite some time to figure out what's up with the paradigm of quantum interest conjecture and the possibility to generate negative energy (even only theoretically speaking). Only from pure interest I have read a bunch of papers on the matter, however I feel...

Hi new to the forum and would like to improve my level of maths. I am working through a text but need some help with a compound interest question. the formula to find compound interest is I = P (1 + R)n–1. P= principal sum R= interest rate n= number of periods for which interest is calculated...

This is my first post on the forums, Hello! my names Tim, nice to be on here! I will keep this as short as possible. In high school, I hated math and loved science. Its a story I hear often. I was bad at math, or maybe it just wasnt introduced to me correctly. It took a lot of soul searching...

Homework Statement "A dollar due to be paid to you at the end of n months, with the same interest rate as in Problem 13, is worth only (1.005)^{-n} dollars now (because that is what will amount to $1 after n months). How much must you deposit now in order to be able to withdraw $10 a month...

I am in a course of Computer Science Engineering.I have noticed about by personal temperament that I learn better on my own than I do under authority. I learn better when I am reading books and studying on my own than when I am sitting in a class and listening to six hours of people talking...

Originally (as far as I know) the number e (ie. 2.71828...) came up in compound interest calculations. For example, if you have 1 dollar, and a compound interest of 100% per year, and the interest is continuously calculated, after one year you'll have exactly e dollars. The generic formula...

Hi. I'm getting my degree this year, and I seem to have lost all interest in learning physics. I don't feel like studying any more, I just don't see the point in it. I was fine when this semester started, I felt very motivated and I even started reading up the recommended bibliography before...

My https://www.amazon.com/dp/0073532320/?tag=pfamazon01-20 (p. 176 Example 7.1) pointed out that an investment ##p(t) = 100\,2^t## (##t## in year) that doubles the capital every year starting with an initial capital of $100, has an (instantaneous) rate-of-change ##\frac{\text{d}}{\text{d}t} p(t)...

Hello So from what I understand, the continuous compound formula finds out the most you can get from interest no matter how many times you compound the interest in a set amount of time. So how come when I plugin in a big number into the regular compounding formula for the rate, the end amount...
