These are great! I loved 8.02 (actually I took 8.022).

Has MIT changed that they now refer to courses by name AND number? Saying “Physics 8.02” is like saying “ATM Machine”

Am I the only one getting a "Certificate Error" from the link ? The link seems to be broken .

It works for me. The site also doesn't load with any certs or over SSL. Maybe you are being MITM'd by your ISP or employer?

I've had this with a number of MIT links recently.

I was getting that error until I disabled the "HTTPS everywhere" extension for the page.

One early misconception I had about EM was that there were discrete 'lines' of force. I guess this either arose from iron filings experiments or from the way the diagrams of fields are (perhaps unavoidably) drawn. But now I know the fields are continuous.

> “ATM Machine”

I maintain that this is fine, interpreted as "the machine with which we associate the name _ATM_".

Section A ("A. Scalar Fields and How We Represent Them") begins with "A field is a function that has a different value at every point in space." This definition is a bit misleading: the value does not have to be different at every point.

I like to use the ATM machine located on Table Mesa, and use the cash to enjoy a cup of soup du jour of the day.
