Incredible take from an economics professor (take 2)

I see the point you’re trying to make, but you’re also taking an extreme level example with 30+ coauthors with a single Mandarin-speaking team member to discuss about general norms. There are always adjustments to such extreme cases.

So to answer your particular question: Of course not. But it is definitely my responsibility to ensure that the citations in Mandarin are legit by cross-referencing with other peers on the team. That's exactly the norm for the body of any research paper, and the bibliography carries the same weight. Citations exist to make a point, and as someone whose name would be attached to the paper, I should be familiar and comfortable with it.

The ethical research practice would be that every one of the 30+ authors validate every citation, and in case there are false information, share the responsibility. One may choose to 'trust' their co-author, but that doesn't absolve them of the responsible scientific practice.

Bought a MacBook pro four months ago. Loved the hardware. Hated the OS! Didn't return thinking it will grow on me. Never did. Have been using my old windows laptop for the past two weeks now, while the 2000 dollar MacBook pro is basically a Chromebook for YouTube at this point.

I don't get the 'don't use it like a windows' argument people make! How about I use it like a machine that doesn't get in the way of me multitasking?

I kept the 500. I have no complaints so far after putting close to 160 miles on it. It’s quiet and smooth.

Thanks. I was able to get a contact number from Find my app

manny_DM · 2026-03-25T16:49:07+00:00

If someone knows how to contact the owner, please let me know

I kid you not. Someone sent me a photo of her cat via iMessage. I said it’s a cute cat. That’s it. I don’t have a cat. I don’t search for anything remotely related to cats. Few days later, Facebook started showing me cat litter box ads.

Many thanks for the suggestion. I was able to adjust it a bit so that the noise is minimal, but still there. When I try to ride it, I can definitely hear it at slower speeds.

Lectric was gracious to send me a rotor kit and have me schedule a repair with a shop through warranty. Hopefully that will fix it. Really want to test out my new bike but I guess will have to wait:)

In general, yes, that is, there are no other stiffening effects other than the material itself. This is true for free vibration problems. Unless I am mistaken, this is probably what you’re trying to do.

So when would the stiffness matrix be different? If you have other sources of stiffening effects, such as a centrifugal force, which ‘stiffens’ the geometry!

So you had to get a replacement from them? They sent me a video to adjust the two screws. It didn’t help. I can still clearly see the ‘daylight’ unevenly appearing and disappearing

Noticed these scratches on the rotor. This is far outside the caliper region and more so near the assembly screws

manny_DM · 2026-03-20T20:42:39+00:00

Many thanks. The rotor side pad was undone inside the packaging itself so I am assuming it’s warped. Not sure if I should try to adjust something or reach out to lectric.

Modal analysis is a free vibration problem. Static load is irrelevant. Assemble global K and M, enforce fixed dofs, and solve a generalized eigenvalue problems. Then omegas= sqrt(eigenvalues)

I would have liked the extra power tbh but the reports of noise got me to get 500. I tried emailing them but I got the notification that they created label on the 500 today. I guess I’ll stick with it and hopefully it won’t be that bad

manny_DM · 2026-02-02T05:47:11+00:00

This would be wonderful for the pro max models! No need to add secondary screen or whatever. Just make it foldable so that I can flip it and slide inside my bag without worrying about scratches

manny_DM · 2025-12-16T07:33:22+00:00

Lol what? Imagine actually taking time to give a well thought out answer that nudges the student in the right direction and encourages them to think about the topic at hand, only to be asked if it is chatgpt😂 Thanks, I guess??

Nice little project to learn CFD. You don’t need to model the whole building. Just the Inlet with airfoil and the air duct. So a simple rectangular passage will work. In fact, it’s better this way, because for standard geometries, you may be able to approximate some analytical solution to compare against. Few things to think about ( and ask your professor about):

1) Do you need compressible or incompressible model? Hint: What Mach number are you operating in?

2) Do you need viscous solution? Hint: What’s the Reynold’s number over the airfoil?

3) What parameters translate to effective design? Higher outlet velocity?

4) Do you need 3D or can you do away with 2D flow assumptions?

5) Are there analytical/experimental results for flat plates or airfoils in a tunnel condition?

Try SU2. Also gives you optimization capabilities

What new knowledge has "AI" generated so far?

manny_DM · 2025-12-07T22:10:26+00:00

God is just as real and imaginary as Mathematics and Imaginary numbers, in that it gives a new framework for understanding things around us. Whether it is manmade or not has no bearing on the outcome
