That's even nicer, I wonder why they use the (1 - V / U)-1 in the lecture? Probably works out easier to apply or something, I'm sure I'll find out when I watch the rest of it. Thanks again!

Wow I'm stupid, thanks for putting up with me. I finally got there I think - ΔTo - VΔTo / U = ΔTs ΔTo( 1 - V / U ) = ΔTs ΔTo / ΔTs ( 1 - V / U ) = 1 ΔTo / ΔTs = 1 / ( 1 - V / U ) ΔTo / ΔTs = (1 - V / U )-1

Sorry that was a mistake I forgot to divide the ΔTs by ΔTo. Now I've gotten this far but still end up with the variables on both sides ΔTo = ΔTs + VΔTo / U ΔTo = ΔTs / ΔTo + V / U ΔTo / ΔTs = 1 / ΔTo + V/U / ΔTs ΔTo / ΔTs = 1 / ΔTo + V / UΔTs

Homework Statement I'm watching this lecture and wanted to attempt to derive the expression for ΔTo/ΔTs Homework Equations ΔTo = ΔTs + VΔTo / U The Attempt at a Solution I have worked out that ΔTs = 1-V / U, however I'm stuck trying to get ΔTs / ΔTo because of the ΔTo on both sides of the...

Unfortunately we'd need someone who had completed a MSc over here to tell us the difference. I really appreciate the depth of your post, and for the feedback everyone else has given. I'm considering starting with an undergrad or MSc in maths and physics to start with and I've revised my timeline...

I certainly could, I'm just wondering if anybody with experience of a UK or Irish masters would have some feedback. Again I only have experience with the undergraduate course I completed but any Irish or UK site I've checked about degrees in general recommends a masters instead of a second...

I think there might be some kind of disconnect between US and EU education here, maybe not. I assume you're referring to US since the PGRE is multiple choice and we don't refer to graduate school over here. I've linked the course I'm interested in in the first post. I'm not saying one or the...

My undergraduate experience was I spent the full 20 hours in classes in year one, even though I already knew 90% of the subject matter. 2nd year I cut that to 4. 3rd and 4th year I only went into the campus when necessary and worked from lecture notes and the library. I'm sure physics will be...

Thanks I appreciate it. Is it the time-scale that is unfeasible in your opinion or the idea of not first going through an undergrad physics course?

Thanks Choppy, I'm not registered yet so if needs be I can push it back a year. In my experience as a (admittedly mature) undergraduate the 4 years of college tends to involve a lot of time wasting. Granted I was not in a hardcore physics subject but computer science does have quite a bit of...

That helps a lot thanks!

Hi all, I'm a software engineer, I graduated in 2013 as a mature student and I'm now at a senior level. I wanted to pursue a Masters degree and I've found an accredited distance learning MSc. in the UK ( https://www.ljmu.ac.uk/study/courses/postgraduates/astrophysics-msc) I'm using...

Hi everyone, Apologies if this is common knowledge or a silly question, I'm just coming back to physics and I've been looking through the double slit experiments ( both double slit and delayed choice quantum eraser ) and it got me thinking about the uncertainty principle. With a photon of...

Oh wow I feel so silly, thanks a million for the help once I knew I wasn't doing something wrong I was able to spot the error. $$\dfrac{\sqrt6}{\sqrt7}\cdot\dfrac{\sqrt147}{\sqrt7}$$ This is $$\dfrac{\sqrt882}{\sqrt49}$$ not $$\dfrac{\sqrt882}{\sqrt7}$$ as I had thought So then it's...

Hi I'm trying to give myself a refresher in Leaving Cert maths and I'm running through some problems. Here's one which has me stumped (sorry I can't figure out how to show the actual symbols on the post, it's just showing as raw LaTEX when I try ) Combine terms and simplify the expression of -...
