QuarkyMeson's latest activity
-
QuarkyMeson replied to the thread I Some confusion with the Binding Energy graph of atoms.What's costing you energy in that case is your negative Q. The product has a lower binding energy (more mass) than its reactants. The... -
QuarkyMeson replied to the thread I Some confusion with the Binding Energy graph of atoms.What I mean by this is, either you get a positive Q or negative Q and that determines if a given reaction is exothermic or endothermic...

QuarkyMeson replied to the thread Admissions PSA -- Contact PI's before applying to graduate school in the US.Maybe you can see if there are plans to limit the 2026 class of first year physics graduate students. :)...

QuarkyMeson replied to the thread I Some confusion with the Binding Energy graph of atoms.Because you're fusing elements after the peak in binding energy your Q will be negative. You need to make up that budget with energy...
-
QuarkyMeson replied to the thread I Some confusion with the Binding Energy graph of atoms.It doesn't get released, it was there all along generally as kinetic energy. No, again, the graph only includes binding energy Q...
-
QuarkyMeson replied to the thread I Some confusion with the Binding Energy graph of atoms.The energy released is simply the difference in masses between the products and reactants. ##Q = (m_1+m_2 - \sum M_{products})c^2##...

QuarkyMeson reacted to Paul Colby's post in the thread A Project Progress Report and possible Radio Astronomy Technique? with
Like.
This is a good question. I’ve done some experimenting separating the radios and shortening the cables from the clock generator. I’ve... -
QuarkyMeson replied to the thread I Some confusion with the Binding Energy graph of atoms.The graph represents what is on the axes- mass number against the average binding energy per nucleon. The average binding energy per...

QuarkyMeson replied to the thread A Project Progress Report and possible Radio Astronomy Technique?.The units aren't correct. You're getting ##\frac{V^2}{Hz}##, which I think would be the noise voltage spectral density across the load...

QuarkyMeson reacted to Choppy's post in the thread Admissions PSA -- Contact PI's before applying to graduate school in the US with Like.
For what it's worth, I think there are a lot of specific details that could come into play. These would include having to make a...

QuarkyMeson replied to the thread A Project Progress Report and possible Radio Astronomy Technique?.So basically a radio interferometer? That's pretty neat, I've always wanted to do something like this. So even when you stopped...

QuarkyMeson replied to the thread Admissions PSA -- Contact PI's before applying to graduate school in the US.The largest department I reached out to was MIT, and I haven’t heard back yet, which isn’t surprising. At this point in the year...

QuarkyMeson reacted to gwnorth's post in the thread Admissions PSA -- Contact PI's before applying to graduate school in the US with
Agree.
That seems rather unethical on the part of the universities to me. -
QuarkyMeson replied to the thread Admissions PSA -- Contact PI's before applying to graduate school in the US.That's definitely fair and it's probably a good practice anyway. I just wanted to warn others that we live in strange times at the...
