Question
Dear Prof Scott

Can we build a Smartphone Doorbell app which will trigger Doorbell rings?.

The smartphone circuit hardware have to be modified to make it work?.

Thanks
Prashant

Answer
With the way things are progressing, we can program any device to do anything for us.  If the people building the smartphones heard that a special beep was wanted for each door in the house, I'm sure they could put it in.

I'm not sure the hardware on a phone would need to be modified if we could program doors to receive calls to unlock them.  All they would need to do would be to design a lock to open when a certain code-word was received from a phone call.  This would probably be added to special commands from the phone requiring a special key to be pressed first.

Before too long, I'm sure that they will start building robots to do many tasks for us, like keeping track of the weather (what type now, future predictions), locking doors (front, back, garage), knowing what food is present (type, age, how long it can stay, how much), answering phone (right now or sending a message they'll get a call back), adjusting TV (turning on/off, adjusting channel, adjusting volume), playing music (bought, radio, getting price), adjust warmth in the house (heat, A/C), calling people (friends, family, coworkers), opening the garage, starting the car, cleaning the dishes, putting food away (fridge, garbage, cupboard), waking people (as an alarm, with a voice,or perhaps music).  The possibilities are endless.

Expertise

I can answer any question in general math, arithetic, discret math, algebra, box problems, geometry, filling a tank with water, trigonometry, pre-calculus, linear algebra, complex mathematics, probability, statistics, and most of anything else that relates to math. I can also say that I broke 5 minutes for a mile, which is over 12 mph, but is that relevant?

Experience

Experience in the area; I have tutored people in the above areas of mathematics for over two years in AllExperts.com. I have tutored people here and there in mathematics since before I received a BS degree back in 1984. In just two more years, I received an MS degree as well, but more on that later. I tutored at OSU in the math center for all six years I was there. Most students offering assistance were juniors, seniors, or graduate students. I was allowed to tutor as a freshman. I tutored at Mathnasium for well over a year. I worked at The Boeing Company for over 5 years. I received an MS degreee in Mathematics from Oregon State Univeristy. The classes I took were over 100 hours of upper division credits in mathematical courses such as calculus, statistics, probabilty, linear algrebra, powers, linear regression, matrices, and more. I graduated with honors in both my BS and MS degrees. Past/Present Clients: College Students at Oregon State University, various math people since college, over 7,500 people on the PC from the US and rest the world.

Publications
My master's paper was published in the OSU journal. The subject of it was Numerical Analysis used in shock waves and rarefaction fans. It dealt with discontinuities that arose over time. They were solved using the Leap Frog method. That method was used and improvements of it were shown. The improvements were by Enquist-Osher, Godunov, and Lax-Wendroff.

Education/Credentials
Master of Science at OSU with high honors in mathematics. Bachelor of Science at OSU with high honors in mathematical sciences. This degree involved mathematics, statistics, and computer science. I also took sophmore level physics and chemistry while I was attending college. On the side I took raquetball, but that's still not relevant.

Awards and Honors
I earned high honors in both my BS degree and MS degree from Oregon State. I was in near the top in most of my classes. In several classes in mathematics, I was first. In a class of over 100 students, I was always one of the first ones to complete the test. I graduated with well over 50 credits in upper division mathematics.

Past/Present Clients
My clients have been students at OSU, people who live nearby, friends with math questions, and several people every day on the PC. I would guess that you are probably going to be one more.
