Atoms, Bits, Circuits<br />

<strong>and</strong> Systems<br />

By Jana Moore<br />

Nanotechnology. Robotics. Photonics. MEMS. Power<br />

grids. Stochastic processes. The fields encompassed by<br />

<strong>the</strong> Department <strong>of</strong> Electrical <strong>and</strong> Systems <strong>Engineering</strong><br />

(ESE) have become so broad <strong>and</strong> complex that even<br />

pr<strong>of</strong>essionals find keeping up difficult.<br />

Freshmen could easily feel overwhelmed by <strong>the</strong><br />

scope <strong>and</strong> breadth <strong>of</strong> ESE, until last fall, when <strong>the</strong><br />

Department took <strong>the</strong> rare step <strong>of</strong> <strong>of</strong>fering ESE 111:<br />

Atoms, Bits, Circuits <strong>and</strong> Systems (ABCs), a class<br />

proposed <strong>and</strong> partially designed by senior Kevin<br />

Conley <strong>and</strong> his fellow Teaching Assistants (TAs).<br />

“To get excited about <strong>the</strong> fields in ESE, it’s important<br />

that freshmen get h<strong>and</strong>s-on work <strong>and</strong> a flavor <strong>of</strong> <strong>the</strong><br />

different things you can do, <strong>and</strong> no one course gave<br />

<strong>the</strong>m that,” says Nick Howarth, one <strong>of</strong> <strong>the</strong> seven TAs<br />

who made an impassioned plea for <strong>the</strong> new overview<br />

class a year ago. Daniel Lee, pr<strong>of</strong>essor <strong>of</strong> Electrical <strong>and</strong><br />

Systems <strong>Engineering</strong>, had an additional goal: “I wanted<br />

<strong>the</strong>m to see how <strong>the</strong>y could change <strong>the</strong> world after<br />

underst<strong>and</strong>ing <strong>the</strong> underlying <strong>the</strong>ories.”<br />

A New Kind <strong>of</strong> Intro Class<br />

Lee <strong>and</strong> Siddharth Deliwala, Undergraduate Lab<br />

Manager, decided <strong>the</strong> lectures needed to take a far<br />

different tack from traditional introductory courses.<br />

“Instead <strong>of</strong> just teaching an overview, we wanted<br />

to utilize energetic <strong>and</strong> engaging guest speakers,”<br />

Deliwala says. “We focused on particular discrete<br />

areas as representative <strong>of</strong> entire subjects.”<br />

Lee addressed a wide spectrum <strong>of</strong> topics during<br />

lectures, from ma<strong>the</strong>matical models <strong>of</strong> circuits <strong>and</strong><br />

semiconductor physics <strong>and</strong> processing techniques<br />

to abstractions <strong>and</strong> analysis <strong>of</strong> large-scale systems.<br />

Guest speakers examined <strong>the</strong> application <strong>of</strong><br />

microelectronics outside <strong>of</strong> computing, <strong>the</strong> potential<br />

<strong>of</strong> nanoparticles <strong>and</strong> <strong>the</strong> complexities <strong>of</strong> power grids.<br />

For <strong>the</strong> midterm, <strong>the</strong> students analyzed <strong>the</strong> Apple vs.<br />

Samsung touch-screen lawsuit from an engineering<br />

<strong>and</strong> technological perspective.<br />

H<strong>and</strong>s-on at a High Level<br />

The labs, primarily designed by Howarth <strong>and</strong> fellow TA<br />

Sam Wolfson, roughly matched <strong>the</strong> focus <strong>of</strong> <strong>the</strong> lectures<br />

while introducing a variety <strong>of</strong> concepts, some <strong>of</strong> which<br />

are normally reserved for juniors. The first lab began<br />

with simple circuits but ended with MATLAB, powerful<br />

s<strong>of</strong>tware used to analyze <strong>and</strong> plot large data sets<br />

<strong>and</strong> control complicated experimental setups. Later,<br />

<strong>the</strong> students learned how to program <strong>the</strong> Arduino,<br />

an inexpensive open-source microcontroller platform<br />

popular worldwide.<br />

The use <strong>of</strong> sensors, LCDs, accelerometers, data<br />

acquisition, signal processing <strong>and</strong> wireless communication<br />

followed, along with constructing a portable<br />

USB charger. All <strong>the</strong> labs built up to <strong>the</strong> final project,<br />

designing <strong>and</strong> building a networked pedometer<br />

that interfaced with MATLAB <strong>and</strong> was capable <strong>of</strong><br />

sharing data with users.<br />
