I've been a user of Mathematica since version 2.2. I am a physicist by training and engineer by trade, and a bit of a poster child for engineering applications of Mathematica. The other M product people look at me funny but are secretly jealous.

comment Entering scientific notation in an InputField
Thanks to everybody for their help. I am not quite ready to attack creating my own control type, so I will study these approaches carefully. I selected this answer because it gives the option of entering the number in normal notation as well as scientific.

comment Entering scientific notation in an InputField
I know this is kind of a weak question since I have already found a workaround, but I wanted to get this behavior documented here as it seems buggy to me.

comment Calling MATLAB from Mathematica
I am using MATLink to drive the Data Acquisition Toolbox on a test system I am developing. I would rather work entirely in Mathematica, but a) I don't believe there is a straightforward way to operate data acquisition systems from Mathematica and b) this approach lets me recycle another engineer's MATLAB code and get up to speed faster. Thanks for the package.

comment Why can I still hear sound when the frequency of the periodic function inside Play is lower than the range of human ear?
oops, that was supposed to be a comment. Too early in the morning to be posting.

Not only can the human ear not detect a 1 Hz tone, I would be very surprised if your laptop speaker could reproduce a 1 Hz tone. Laptop speakers are tiny little things and are way smaller than a 1 Hz wavelength of 343 meters. The only you could possibly be hearing under a continuous sine wave would be the very high distortion products of the speaker and the amplifier. Since you are probably not driving the speaker that hard, I would have to vote for the sampling noise as being the source. (Source: I am an electroacoustics engineer.)

@Rojo Good point. That would follow better practice. I shall have to play with that.
