Re: Who needs a pencil for math, anyway?

Martin. Max

I have an iPad app that lets you draw equations with your finger

Windows 7 and 8 have a "Math Input Panel" in Accessories (actually it may be named slightly differently in Windows 8, I must check at home) in which you can use your mouse to enter the mathematical symbols. And better than a screen shot it handshakes directly into Word. I must check on my newly acquired Surface how it works with a finger input.

That sounds interesting -- what's the name of that App?

It sounds like a horrendous incident -- when will the movie be coming out? :-)

@MeasurementBlues: It comes from erasing all those math problems when you realize you did them wrong.

The main thing is that you aren't bitter :-)

I have an iPad app that lets you draw equations with your finger. It cleans them up, making them easy to read, and evaluates the equation. Then, just take a screen shot. Who needs a pencil?

After an 2009 auto accident in which I injured my thumb, It's hurts a bit to write so I type whenever possible.

The biggest problem with pencils for students is the eraser wears down long before the lead is gone. It comes from erasing all those math problems when you realize you did them wrong.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
