John Leeman (@geo_leeman) spoke with us about geophysics and associated technology.

John is one of the hosts of the\xa0Don't Panic GeoCast\xa0(@dontpanicgeo,\xa0iTunes). Some episodes you may like:

• What if you calibrated your candles differently?
• Out of the Country\xa0(Brad Jolive on moon rocks)
• "Rock Drills and Beer" Undersampled Radio

John is teaching a course at Penn State called\xa0Techniques of Geoscientific Experimentation. The information and textbook is online! It uses the\xa0SparkFun Inventor's Kit.

John has a\xa0website with a blog. He has some Cheerson CX-10 tiny drone posts (my favorite, also\xa0Alvaro's repo\xa0and\xa0my posts).\xa0John also has a consulting company:\xa0Leeman GeoPhysical.

Python! Lots of Python was discussed.\xa0

• Jupyter notebooks\xa0(here is a good tutorial)
• Example of reproducing a figure from a paper
• John's friction model (repo\xa0and\xa0talk he gave about it at SciPy2016)
• Neat SciPy talk about open textbooks
• SciPy is a Python conference\xa0in Austin, TX in July
• Finally, in lieu of rock puns,\xa0here is a neat animation\xa0showing many different waves from earthquakes.

Contest! Contest ends October 1st and now there are more books! In addition to the ones Bob Apthorpe is sponsoring,\xa0John's consulting company\xa0will sponsor:\xa0Earthquake Storms: An Unauthorized Biography of the San Andreas Fault by John Dvorak\xa0and\xa0The Soul of A New Machine by Tracy Kidder.\xa0
