Anyone know why on earth did @RodrigodeAzevedo get suspended?

@M.A.R. Of course. You could be mistaken for St. Mark though.

I was wondering, is it ethical for me (with access to the full text of most journals) to share the pdf with others (without access to full text)?

Heyo: does anyone have any idea why Zinc ferrocynide is white?
The ferrocynide should have given at least a tinge of yellow.

@uhoh I'm grateful for that.. just hoping someone gives a good answer though! We're designing wheels for my institute's mars rover, and I want to understand the reasons behind many features. Some I found, some just leave me in the dark.

@uhoh Wow!

@uhoh looks like my question ain't getting an answer here either 😅

What do you think?

William R. Ebenezer

Jun 2, 2020 16:10

So it would fit in here, contrary to what I thought earlier.

Q: Rover Wheels: Convex or Flat?

I was comparing the wheels of the Curiosity rover and the Perseverance rover and noticed that the latter had a very flat cylindrical design as compared to the former. This got me thinking about which wheel profile was sturdier. That got me thinking about various things that might be different....

have you crossed 100k before? (you do award hefty bounties)

@uhoh I can see that! Looks like you were almost going to do a feature-request for a rep-cap.

Q: Aborting a de-oribit manuver

I was contemplating on how a de-orbit may be abandoned post completion of the orbit burn, say, from LEO. A situation in which this might be necessary would be detecting a breach in the heat shield after the burn or any other emergency situation. Are there standard procedures to abort de-orbit? O...

@YusufHasan The last mail from the registrar says that they will start bring people back in Sept. But no (official) info about when the sem will start

@YusufHasan Oho... nice.

William R. Ebenezer

Jun 16, 2020 16:40

@YusufHasan I know your agony. We were also going to have a chem class test and were given just 8 days to cram the entire Inorganic and Organic material. But the students mass-mailed our profs and they had to cancel it.

@YusufHasan Our semester was closed recently without endsems. Classes concluded long ago.

@YusufHasan College opened? Semester closed?

Hello folks.

William R. Ebenezer

Mar 22, 2020 15:14

@YusufHasan I can counter that with two points. Tell me if I'm wrong. 1. All d-d transitions are forbidden anyway, but the vibronic coupling at room temperature is enough to distort the centrosymmetry of the oh complex, relaxing Laporte rules. 2. Potassium ferrocyanide is a nice yellow. Surely the same logic applied to it as well!

@GuruVishnu Right.

@Help I haven't done much spectroscopy, but I think the blank should draw a zero. Probably not calibrated.

I relied heavily on FIITJEE modules as well, including the GMP towards the end.

William R. Ebenezer

Mar 10, 2020 13:10

Physical: Cengage (not recommended, very crabby book), O.P. Tandon (not recommended either), Atkins at times. I didn't use any reference books seriously for Physical, as nobody's gonna ask you whether you understood stuff deeply or not, something I'd have loved to do.

William R. Ebenezer

Mar 10, 2020 13:09

@GuruVishnu Heyo, sorry for the delay. Was a little busy. I used a lot of books! Organic: Solomon&F, Peter Sykes, Sanyal, J.March, and Clayden just for a few topics. Inorganic: Lee (sadly!), N.Greenwood (only for a few topics, not recommended for JEE), Shriver and Atkins.
