Thank you!

Hello everyone! I was going through a simple high school level mathematics book and got to the following question: n2 - n + 41 is a prime for all positive integers n. You're supposed to find a counter-example and prove the statement false. You could of course sit and enter different...

Thank you Lord Jestocost!

Hi James! You're absolutely right. I needed only a very simple overview of these systems just to get me going. Meaning that, for example, when I'm talking about the "avoirdupois" system, what is this thing that I'm talking about. That was missing in the book and then I had to read Wikipedia...

Thank you for the valuable work you're going to do. Much appreciated Greg!

I apologize. I just changed that to "Not in School." I chose that option by mistake when I was creating my profile.

I don't attend any schools. I have been reading on Wikipedia for a few days. It's not bad. There's pieces of information here and there in different articles but it's not easy to make sense of them all because the information is not complete and also, there's a lot of contradicting and...

Hello everyone! I would like to ask a rather comprehensive question. I would appreciate it if you could help me with this. I have started reading a chemistry textbook recently and typically in the first chapter of any basic chemistry course, you come across, measurement, unit conversion, etc...

Thank you DaveE. Your explanation clarifies things for me a lot more.

Hi Borek. I think I get your point but would you explain a little bit more please. Thank you!

Thank you Dale with the pdf document. I think I understand what you're saying but I'll have to read the pdf document and moreover think a little bit about the good example that you gave here. If I have any further questions, I'll post them here and your kind assistance would be much appreciated...

Thank you Wrichik! :)

If you read any introductory physics or chemistry course, in the very first chapter, you'll come across measurement, uncertainty, etc. There, you learn some rules about rounding off numbers, etc. One of the rules discussed there is that if you add/subtract two numbers with different decimal...

I have been teaching basic mathematics, like high school core concepts, for a while now. I could help others with that. I might need help with physics myself.

Hello everyone. My name is Garha. I'm 40 years old. I am working on a project in electronics that needs a little bit of science, physics and math. I am not doing any courses at any university or college. Whatever I happen to need for my project, I find the relevant books and read them. In the...
