Comments like these are why I lurk on HN. Genius solution. As a birder I have thousands of bird photos and would pay for this service.

This would be primarily aimed at the large number of students who have to take organic chemistry as a requirement. For organic chemistry graduate students and professional organic chemists, all this stuff will largely be so ingrained as to

On one hand I love this level of nitpicking. On the other hand, by the standards of what an undergraduate organic chemistry student is looking for from a free online resource, and given that it is just one guy doing this, in his spare time,

Two most extreme stories I am most familiar with (did not experience first-hand) were of a PI throwing a chair in the direction of a postdoc, and of a PI having a screaming fit directly in the face of a graduate student. Both assistant prof

It's pick your poison, like choosing a startup vs BigCorp. My observations pertain to organic chemistry specifically, I'm less familiar with other fields. With an assistant prof you will be asked to do unreasonably long hours on

An early stage lab has a lot in common with a startup. The PI is given seed money to validate an ambitious idea and has limited time and resources to do it. The work is extremely labor intensive and in the early stages the PI will be in the

I run a fairly well-known organic chemistry website. Occasionally I receive notes from amateur chemists who want advice on various aspects of lab prep. Sometimes they are amusing, like getting late night calls from amateur CBD chemists. Oth

I pass along this amusing advice, no doubt familiar to you, but probably not to the general HN readership. "Gattermann (Ann. 357, 318 (1907)) recommends that the operator smoke during the preparation [of HCN], for he found that a trace

The Siberian silver fox study makes it very difficult to avoid the conclusion that behavior (e.g. tameness) in canines is a heritable trait that can be selected for. Beginning in 1952 wild silver foxes have been bred in Siberia selecting so
