[edit] internal links

There are far too many of them in this article. —Preceding unsigned comment added by Icarus66 (talk • contribs) 16:07, 22 September 2007 (UTC)

[edit] Misleading summary

i like to scratch my head while under water eating applesauce...oh, anyway, back to millikan.. In contrast in the method section it's shown that Millikan did not balance the electric and gravitational forces on each drop, doing this would be really difficult, instead he observed the YOUR MOMS GRANDMAS UNCLES SISTERS STEP BROTHERS POMERANIANS GREAT AUNT LAkISHA..WAS ROBERT MILLIKAN. GO JAGS

Difficult doesn't begin to explain it.  :) Millikan must have had the patience of a saint, I swear. -- Popefelix 00:17, 26 Apr 2005 (UTC)

I'm also striking out the broken links in the article, and adding one or two of my own. -- Popefelix 00:26, 26 Apr 2005 (UTC)

I updated one of the broken links, and e-mailed Dr. Covault to see if he has a current URL for his oil drop lab. In the meantime, the Covault link has been deleted. -- Popefelix 00:47, 26 Apr 2005 (UTC)

[edit] type of oil?

The oil used is the type that is usually used in vacuum apparatus. This is because this type of oil has an extremely low vapour pressure.

Would it be possible to be more specific? There's nothing helpful at vacuum. Chick Bowen 04:51, 10 October 2005 (UTC)

Nowadays in student labs liquid latex is used, HTH. --Bmalicoat 05:30, 1 March 2006 (UTC)

[edit] Charge screening?

Wouldn't the QED concept of charge screening invalidate oil-drop experiments? That implies that the real charge of an electron is actually significantly larger than what such an experiment could measure, and that one was only measuring the effective charge at some particular distance. -76.209.50.77 17:42, 27 October 2006 (UTC)

[edit] Authorship controversy

It is now known that Millikan devised and conducted this experiment in collaboration with his grad student Harvey Fletcher. I've added this to Fletcher's page, but it ought to go here as well. Posting this in case I don't get around to it and someone else wants to. Electrolite 22:04, 4 February 2007 (UTC)

[edit] See Also section

I've removed the See Also section per WP:LAYOUT, which says that such sections "should ideally not repeat links already present in the article". Robert Millikan is prominent featured and wiki-linked in the text already. Electrolite 03:34, 12 February 2007 (UTC)

OK. I agree with you. Thanks. nicky_008 15:40, 12 February 2007 (UTC)

[edit] Check it out!...New pictures on article

I have added some pictures that usefull for article such as the orginal Millikan’s oil-drop apparatus picture, Millikan's setup for the oil drop experiment, etc. Let's check it out or add some more. nicky_008 18:06, 20 February 2007 (UTC)

[edit] check the method section, the last equation

In my mind, it should be qE=\W(1+\frac{v_2}{v_1}\)\?

[edit] Rather expensive and difficult to do properly?

Request change in last sentence of "Background", my professor told me that he did that already in high school. Maarten,dutch (talk) 18:30, 7 February 2008 (UTC)
