This time we're talking with Professor Michel Maharbiz on the ethics of cyborg-idizing beetles to remotely perform commands with electrodes and radio signals. We get deep into how micro biology is pushing the frontiers of science in new and interestingly morally complicated ways.

Directions of Chemistry, with Christopher Cramer
In this episode, Professor Christopher Cramer of University of Minnesota explore recent and future developments in chemistry, broad as that may sound. We step a bit into the weeds of his research in polymer development, and talk about the potential growth of science in curricula in the United States.
Dr. Charles Ferris State of Petroleum Engineering
Petroleum Engineering has a bad rap; is it deserved? In this episode Dr. Charles Harris and I explore some of the myths behind petroleum engineering, the direction of the industry, and what the future holds for petroleum engineering.
A Chemical-filled past, present, and future, with Christopher Cramer
How often do you stop and think, I'm a massive chemical? In this episode, Professor Christopher Cramer of University of Minnesota and I explore how chemists push the boundaries of the building blocks of our existence, hopefully toward a sustainable future.
Electrodes, Ethics, and armies of remote Control Beetles, with Michel Maharbiz
A discussion of the ethics and implications of biological engineering in developing tools on the scale of nanometers to electronically control beetles, and treat cancers.

Tomorrow in Engineering
May 25, which is one less than May 26, which is when I fly back to Norcal to see my family, where I'll give my sister a pet succulent, since we'll be celebrating her graduation from highschool, which is a monumental moment in a person's life, but perhaps exaggerated by our culture, which likes to simplify the longitudinal intricacies of life into fleeting moments, as if moments were akin to the many products that are bought, sold, and eventually thrown away...
Also, I did science today.

Today in Engineering

We did a thing with op amps and called it an oscillator.
We created a signal up in LabView. It looked like this: (and by LabView I meant everycircuit)

LAB: Oscillators
I notice this lab is made simpler if we can use Fourier transforms on the circuit components. But I'll hold off on that.
PRELIMINARY WORK / DESIGN Design an OP AMP Relaxation Oscillator having a frequency in Hz equal to the last 3 non-zero digits of your Student ID Number (such as 274). Choose convenient values for the capacitor C and . Determine the value of R using the formula for the period T. Test your design using EveryCircuit and the model for the OP27 OP AMP.
LABORATORY PROCEDURE / RESULTS Each group member will construct the circuit that they designed and simulated. For each circuit, measure the OP AMP output voltage and the voltage across the capacitor using the oscilloscope. Record a rough sketch of the voltages in your laboratory notebook. Use the storage option to save a copy of your results for publishing in your lab report. Your lab report should include all design calculations and any necessary modifications. Be sure to comment on how well your results agreed with the theoretical calculations. If things didn’t go as they should have, explain what may have gone wrong.
