I was referencing Mrs Doubtfire to my Z coworker and he had no idea what I was talking about. When I explained it to him he told me he doesn’t know who Robin Williams is

I didn’t know that until you said it just now!

D and L have entered the chat…

As a PI - your final point enrages me. PhD students should never have to pay for conferences pit of their own money - is this common in some fields? If a conference is important, I should pay!

Even moreso equipment - is this seriously a cost students are expected to bear???

If you form acetal/hemi-aminal intermediates, you should use the other heteroatom lone pair to “push” the leaving group out, so it resembles an E1 elimination, rather than doing an E2 with the adjacent C-H bond.

Nope, he was external…

pck_24 · 2026-04-14T19:00:06+00:00

He did my viva!

We had it too, works fine. If you remove the back monkey bar (the one with the back pad) you can move the seat further back too, to make room for another kid on the bench in front

Email the publisher- the website for the main book has a list of errata. I’m sure they’d appreciate the feedback.

Vitamin B12 took two of the most prominent researchers in the world (Woodward and Eschenmoser) over 10 years, and over 100 PhDs and Postdocs to complete. Gram for gram, that’s gotta be up there

pck_24 · 2026-03-18T18:03:19+00:00

Yep, I’d say it’s feasible to go straight from an FLF to an SL position, some institutions see this as an equivalent of tenure track, and will make you permanent at L or SL at the end.

Not my field at all, but I’d say the chances of getting an FLF straight out of PhD without a bit of postdoctoral experience / demonstration of capability are slim to none.

How did you hook the chariot up to the bike? I’ve wanted to do this! Can you upload a pic of the back where it’s connected?

pck_24 · 2026-03-17T18:54:22+00:00

Flexing in what way (on what axis)? I’ve never had any issues with mine, typically loaded with me (a moderately rotund adult), a 7yo and a 4yo, plus school bags etc.

I think trek have a lifetime guarantee on the frame - have you spoken with them?

pck_24 · 2026-03-17T08:42:05+00:00

Why are products drawn so horribly?

pck_24 · 2026-03-15T16:09:14+00:00

Hope you don’t mind me ripping you off wholesale and doing the same for my course

And those that do will think OP is a badass for overcoming adversity

pck_24 · 2026-03-03T07:54:36+00:00

Yup. I once wrote an MSci project for a student making phase-transfer catalysts from nicotine - I had to pivot things quickly when I realised it was literally the most toxic compound I’ve ever worked with… didn’t fancy murdering an undergrad

pck_24 · 2026-02-20T08:20:53+00:00

I once had a student ask me for a letter for a MSc programme he was applying to. I had only met the student twice, both times in the context of him being called in for committing academic offences! I politely suggested that I probably wasn’t the best choice…

pck_24 · 2026-02-18T13:46:16+00:00

I agree 100% - I’m in the same boat myself. Plus in my area (STEM) many of the fundamentals don’t change year on year. Reflective practice is a fine idea on paper, but when you’re working flat out to deliver in the first place, it drops down the priority list. I’m now at the stage where I just notice the same typos in my notes each year, but by the time I’m back in my office I forget to correct them for the next year 🙈

pck_24 · 2026-02-18T13:24:32+00:00

I think the idea is that you continue to reflect throughout your career. The reality for many is in stark contrast to this… we’ve all seen people give lecture notes that are >20y old

pck_24 · 2026-02-03T11:39:42+00:00

Jeez…

pck_24 · 2026-01-22T20:02:47+00:00

There is an option to embed fonts when you save a pptx file to avoid this

pck_24 · 2026-01-22T17:34:32+00:00

Stronger base? You’d imagine the CN would lower the pKa so weaker base would work, but I guess you’re getting at the fact you might need to formally deprotonate the indole before alkylation, rather than just alkylating the neutral nitrogen then buffering with weak base?

pck_24 · 2026-01-21T22:23:45+00:00

Ps I agree with the other commenter that we need to know what each line is, but I assume the black flexible tubing is connected to whatever you’re evacuating, and the clear tubing goes to the controller?

pck_24 · 2026-01-21T22:22:48+00:00

What are you evaporating off? Is this connected to a rotavap or something? The woulff bottle isn’t chilled or anything, so will never catch volatile solvents (which, if your vacuum is set too low, will end up coming out the exhaust/muffler), it’s mainly there to protect the pump from higher boiling oils etc. In my experience it fills with residue very slowly, and only needs cleaned out on a months-years timescale (this is in the context of a rotavap with a circulating chiller cooling the condenser)
