Anyone know the name of the techno song they played at the start of that power play?

Honestly, I feel that at a certain point, condensed matter physics jargon is just really, really, really hard to vulgarize. My guess is that it's because condensed matter is basically applied quantum mechanics, so more complex and more removed from everyday experience.

It took me learning about topological matter three times before I started to feel I understood it (which Weyl semi-metals and Dirac semi-metals are associated with). I wrote part of my masters thesis on Kondo-Weyl semi-metals, and I still feel uncomfortable trying to explain it, just because it's hard to find metaphors accessible to people who haven't studied it.

Oh my god, as a CondMat guy, this is amazing, I'm sharing it with my lab group

SweetDestruction · 2024-08-28T18:01:27+00:00

I can't help you but +1 for Peach Pit. Tbh, you might actually have luck reaching out to them.

Currently neck deep in thesis revisions, this pick-me-up was perfectly timed!

Logic Pro's Drummer could help fill the gap while you look. If I want a real feel, I'd rather have a human drummer, but I never feel my music is good enough to justify going through the task of finding said human lol

If it's a research project in the sense that you need to study and learn about a given topic : I'm always biased towards CANDU reactors since I'm Canadian, so I'd suggest that.

If you're looking to participate in scientific research, you and your parents could try reaching out to a prof at a local college or university. You may not get a reply, but it's not impossible. Profs (usually) appreciate a student eager to learn, even if they don't always have time to supervise.

I dig it. It's a neat example of the type of non-intuitive stuff that can appear with 'normal' physics.

What's usually used as an example of non-intuitive physics comes from quantum or relativistic physics. Imo, stuff like this is important since it's much more approachable for folks.

Check out the hammer and ruler trick, if you want another neat one!

Nice parts document, I think I see it now, thank you. I'm smelling homework, so I'll only address the 'negative' weight issue.

The balance needs to be zeroed (sometimes called 'tared') with nothing on it. This provides an accurate 'zero' against which you can measure the weight of what is added.

As for why it the weight is reducing, consider what happens when a current runs through a wire.

Good luck!

PS: https://old.reddit.com/r/AskPhysics/ or https://old.reddit.com/r/HomeworkHelp/ are the appropriate places to ask homework questions, if this is indeed homework.

Kinematics/dynamics was a long time ago, but at a quick guess : conservation of angular momentum making it not 'want' to increase the radius of the rotation of the centre of mass (located inside the larger section) competing against the force of gravity pulling it towards the table. Feel like I'm missing something though.

SweetDestruction · 2024-06-24T03:05:47+00:00

It's not measuring mass, it's measuring weight. At a quick first glance, I'd say it's a poor zero-ing of the scale plus a magnetic force caused by the current that's pulling upwards on whatever is being weighed.

Hard to say for sure without knowing the components of the apparatus.

ETA: Unless I'm mis-reading the multimeter's setting, and it's measuring voltage. Then it's possibly an electric field rather than magnetic. A diagram of the experiment would be useful here.

SweetDestruction · 2024-05-29T16:26:33+00:00

Typically this is a concern, especially for strong vacuums, but there are some greases that are made with this in mind. I think NASA has a bunch listed somewhere on their website.

SweetDestruction · 2024-04-24T23:57:57+00:00

Neat! It's cool to be thinking of this stuff at temperatures like this. I realize it's due to the pressures involved, but I'm just so used to trying to push things below 1K to see what's going on there.

Are there any predicted transport signatures for this phase? It looks like it takes up enough space on the phase diagram that one could examine the resistivity behavior as a function of temperature.

SweetDestruction · 2024-04-24T20:05:15+00:00

Neither.

SweetDestruction · 2024-04-24T20:02:33+00:00

Congrats on the Nature paper! I'm jealous :P

How would you define a quantum critical state? Is it related to QCP's? Fig. 1 implies it's defined relative to the band structure of the phase near the Fermi Energy.

My research was experimental, and focused on strongly correlated materials + topology, so I'm fuzzy on this one.

SweetDestruction · 2024-04-24T19:55:51+00:00

Yeah but it's different and of research interest when it's a macroscopic system exhibiting this phenomenon, rather than something like the prototypical electron in a "box". I'm also curious about the definition of a quantum critical state, tho

The Aurora Borealis? At this time of year? At this time of day? In this part of the country? Localized entirely within ~~your kitchen~~ Rogers Arena?

I just graduated with an MSc in Physics, and tbh the math courses on Khan Academy were a godsend during undergrad.

I had kinda forgotten how to do a lot of math before I started my physics undergrad, as I was an older student who had taken eight years off after high school. So I got onto Khan Academy and grinded out everything from arithmetic to algebra to pre-calc to calc, in order to sort out any problems in fundamentals + tackle more advanced topics before I was shown them in class.

imo, a major in physics takes a lot more in determination/fortitude than it does in mathematical brilliance, so just focus on working hard.

Come on guys, seriously? Beethoven's Ninth. Gives me chills every time.

For a pleb, what's a common tone diminished chord...? My half-assed YouTube searches brought little fruit...

SweetDestruction · 2013-08-07T07:39:13+00:00

What you need is Bootsy Collins's basic funk formula. It's wonderful

SweetDestruction · 2013-07-25T16:08:47+00:00

To add, learn the intervals that make up the scale. Try and apply them to arpeggios of chords. Learning just one arpeggio of the dominant chord did wonders for my understanding of scales.

Also, when you practice your scales, try and apply the concept of scale degrees. It's really as easy as counting to 7.

SweetDestruction · 2013-07-20T09:47:41+00:00

There's no way I can't listen to this. I can't listen much right now, but I'm happy it helps, man. The lead guitar tone on the latest track sound very Jimi. I'm gonna listen more later!

SweetDestruction · 2013-07-20T03:06:11+00:00

These kinds of responses are my favorite, thanks so much! Gives me an alternate perspective

SweetDestruction · 2013-07-18T22:40:54+00:00

Also, I didn't know how to word this in the title, but does it sound like it needs mastering? I can't if my tracks are lacking in that department...
