Smart phone for lectures?

I wonder whether any of you has a smartphone and has knowledge or experience with connecting this to the LCD projector for big screen display. I recently learned about the Samsung Galaxy Note phone and am told that (a) it runs ppt files and (b) it can connect to a projector via a USB-to-VGA cable. Do earlier versions of this phone (Nexus or earlier) allow for this also?. I feel that the Note would be absolutely great because of its tablet and screen writing (with a stylus) capability. In fact if it works like that, and flawlessly, it might become the traveling lecturer's preferred device for lecture delivery. What do you think and what experiences do you have? Your comments will be important to me and my possible decision to plunge head first into the smartphone user pool. This dive of course is not cheap - in Canada the Note costs 200.- up front plus three years of monthly 50.- for a minimal plan.

I am not at the forefront of app users (as I don't have (as yet) the needed device) - but this add by Medscape caught my attention. It loads to both i-devices and androids or some ibooks. Is anyone using it, would you want to share your views or experiences with whatever you are routinely using in your studies? Let us  all know by adding a comment!

Make practical sense of terms and definitions

How about these problems:


If the drug concentration is 5 mg/L, then how many  milligrams of drug would you have in each litre?
If the infusion rate is 10 ng per hour, then how many nanograms does the patient get each hour?
If your initial salary as a resident is 40 K/year, how many dollars will you receive each year?
(Please see answers below!)


Well, maybe the above questions are more complicated than you think. Look at the following video - I believe the lady in there is a former student of mine...! She eventually got her MD by marrying one!

Answers to problems:

Ingenious New Method of Exam Grading

Writing good exam questions and grading exams is an art - not a science. Some of my colleagues think they can write 100 questions and come up with a scientific analysis of the results that gives you an absolute and fair grade. Nonsense: there is no intrinsically absolute value in a question, or in 100 questions, and in the end everything is relative! For the most part this then is fair and good enough - but maybe we could do one better by adopting Mr. D's ingenious and intuitive method, as shown in this video:
