Why complain about algebra?  Perhaps the problem is the way algebra is taught and is expected to be understood and learnt.

This is nonsense.  When a reputed organisation states that some study is necessary for engineering, it is almost certainly right.  When it states that some study is unnecessary, it is definitely wrong. [After: Clarke's First Law]

This article which linked me to A Message to Garcia.  Hubbard, 1899.

I think it is standard fare in the army, etc..  At least in the Royal Navy, it is.

I think it should be recommended for IIT Profs as well.  There are a majority who will need the dose.  Even in IITB, the trend over the years is from the directive style to the detailed style.  One just has to browse through the meetings of the Senate of IITB.

I remember the good old days where the contents of a course were prescribe in no more than 150 words.  Often, within 100 words.

Compare this with the prescription of a course in a typical Indian university (or autonomous college).  At least 400 words.  Split into units, weeks, lectures.  I used to think that only robots can do justice to these.

In IITB, among colleagues and administrators, I was either popular or unpopular.  Now I realise that the reason was my directive style.  ("Do it the way you think best.  I will back you up and sign a reasonable number of papers.  But I do not want any complaints from Stores, Accounts, and Audit.")

I dug further.  It seems many things re: Rowan (the hero of the essay by Hunnard) are fiction or folklore.  Please see, e.g.,
