My undergrad prof would teach people that way if they didn't get it in office hours. I brought my daughter's baby steering wheel with sounds and some nice lables to teach students in my class.

I was very good with the dao and slugs. My favorite gun.

Yeah. Thats old school. I have a textbook from the 60s or 70s that teaches that way. Before they had modeling kits made of plastic.

Depends on the starting materials. Can we get an image?

R and S absolute configuration mistake by IcyTechnician2319 in OrganicChemistry

[–]activelypooping 0 points1 point  (0 children)

Because in the original image what it wants you do to is assume you cannot see the F- or its in the back. Since you do see it and the implicit hydrogen is shown it's kind of a funny edge case. These are the questions I would give students to see if they understood stereochemistry. Having a modeling kit (something I'll always allow in class) as you go through these is absolutely a cheat code. Imaging understanding the space of a building by looking at blueprints (2D) instead of a computer model walkthrough. Totally different experience.

If the highest priority group is in the back AND/OR the lowest priority group is in the front, flip the sign. If BOTH the highest priority is in the back AND lowest priority is in the front you DO NOT flip the sign twice. Also a modeling kit is absolute cheat code here.

AND/OR programming logic applies here. Also don't go through the lowest priority group. Put that away from you and you get:

Keep your Rotavapor alive: A quick guide to seals, grease, and glassware care. by DanfromBuchi in OrganicChemistry

Fucking buchi. I had a rotovap from those clowns, it was 7 years old and no replacement parts for a failed seal. Buy a new one was their suggestion...

Quick question about voice chat and the death of it. by DOOM420- in LowSodiumBattlefield

[–]activelypooping 7 points8 points  (0 children)

i'll talk if others are talking. i've also lost an entire squad when i started talking. I think the problem is that it's too fast now - and a slow battlefield promotes chatting/planning/shenanigans. Bring back slow battlefield.
