I have been studying discrete mathematics for fun and I am kind of stuck on this bijection problem.
1. Homework Statement
I wanted to apologize in advance if i put this homework question in the wrong part of the forums. Discrete Math and much logic math is a computer science type math of...
Hey everyone,
Random question.
Does anyone know any good childern's books about Newton's laws or catapults? I was thinking about getting a gift for my cousin who is turning 10 soon. He really likes catapults so I was thinking about getting him an educational book about catapults...
First thanks so much for reviewing!
In the future I am hoping that similar apps get developed on the other types of phone. However, the iphone's app that does the same thing was taken down. Most people know that app as einstien's pedometer app.
Yes, its supposed to be, esle you phone would...
Thanks mfb, I felt kind of silly, but I wanted to confirm that the two redshifts were infact different. In fact, this helps clear up some of the confusion I had about a line from my old professor's lecture notes:
It seem like most of the test of Graviational Redshift are either ground based...
Hey guys,
I feel like an idiot for asking this. However, I wanted to make sure that my head was screwed on straight before I asked my old astronomy professor permission to use some of his old lecture notes.
Is gravitational redshift one of the causes of Hubble's Law? Is the Redshift of the...
Well one thing you should realize is there is a lower limit that we can apply Rs is one of debates of String Theory vs. Quantum Gravity.
For example, string theory would make the lower limit the "length of a string", but quantum gravity makes it a much smaller Plank length.
Now if you...
Ok here it is attached. Also Question 3 is more an open ended question to get students to at least look up the speeds of different particles or time dilation experiments. I do actually take yes for an answer on that question even though I think personally that the answer should be no.
Hey everyone,
Recently I have been working on my teaching degree and doing field experience. Because relativity is part of the Georgia Science standards, I had to make a relativity lab. The experiment is actually measuring time dilation using GPS in the phones similar to Hafele–Keating...
Physics teacher and physics professors need to come up with a better definition of nonlinearity if we expect our students to pass any basic physics course. This is because of how education has changed over the past 10 years. I hope in this thread, we collectively as members of this forum can...
Main Question Back:
Actually, I show the teacher your replies. Both she and I agree with you completely. What do you think would be a better definition that eight graders might understand?
Minor Comment:
Sorry I forgot to explain that the book literally defines "potential energy is stored...
Hey guys,
I am in a teaching assistant in another 8th grade science class for my 2nd field experience in a title 1 school. The teacher is really struggling(*) to explain to the students the difference between Mechanical and Kinetic Energy.
The book their using defines Mechanical Energy as...
So right now I am working on an amature astronomy project to develop a simple lab about the sun's declination. I am borrowing the cheapets linear polarized sheets that I could find ...
Because they are least 10 - 15 years old, I would really like to clean them, but I don't know what to use...
umm... did I post this in the wrong thread again?
I meant the teacher education forums of PF, but its gets confusing sometimes with the differences between Homework, Career Advice, etc.
Right now, I am in student in graduate school MAT program, so I can be come a high school physics teacher. One of the things I am really struggling with is understanding and applying informal assessments.
Beyond simple student feedback, does anyone know of concrete examples of informal...
