Why has the price of petroleum dropped so far in 2014-15?
Deep beneath the Gulf of Mexico are salt layers that mess up seismic waves going through them. I prepared a 10 minute lecture on how some young student might resolve that problem and make for themselves a load of money seeing all the oil under that salt.
Who is blocking congressional testimony at youtube? It sure did look like Wall Street. But, I found out that it's not.

I have finally found a use for Jensen inequalities, (7 page PDF) and video (18 minutes)
Ground roll: suppressing it while mapping layer thickness (SEP seminar December 6, 2013). The video. The document. Revision for seminar 5-22-14.
I narrated the textbook I've been working on for the past two decades. It is 60 talks, average length is 11 minutes. The purpose is to "flip" the class. Students view the video at home and come to class to ask questions and solve problems.

My ideas on Capturing slide shows for redelivery: the revolution that will replace books and videos
Intelligence: what is it? Everyone has a different amount of it. It is politically incorrect to speak of a person's intelligence or their beauty or lack thereof, all of which are given to us at birth. What is intelligence? We Americans are impolite to speak of it. Chinese have no such hangup. They put big money in studying intelligence. Want to hear what they have to say?
Marine seismic debubbling and de-Rickering, a project report article later published in Geophysical Prospecting. Here's one place to start.
Upcoming SEG meeting (Nov 2012). Here is my practice talk. and Here are my slides.
I gave a lecture to some high school students on the topic of MIT Scratch. Don't look at my lecture, instead see video produced by Mitch Resnick, its founder. Inspirational!
My 3 minute slide-show on cats, astronauts, and angular momentum. (It is slides that are better viewed in Adobe Reader than in browser.)
I release my latest ideas on Mostly causal deconvolution clarifies marine seismogram polarity, a 23 minute video at youtube and slides. After you see this video, if it's not flying too high over your head, you might like this more advanced talk, Sparsity deconvolution in the log domain with variable gain, a 31 minute video and slides. Please send feedback to both me and antoine at sep dot stanford dot edu .
Here's a background article to my work of recent years. My professional product of the last couple years in a 4 page abstract.
Want to hear me speak? Here I am speaking to an audience of earthquake seismologists, telling them a little of exploration seismology and something that might help them out.

Apple's iPhoto, I abandon with prejudice
In the interest of optimally compartmenting the School of Earth Science, I gave out a questionairre to members of the Stanford Earth Science Faculty to identify colleagues closest to them in curriculum. Results were input to a "banquet seating" optimization program.
I've started on a history of reproducible research.
I've written a book review on a book by Mathew R. Simmons about the decline of Saudi Oil fields.
Bob Clapp and I have been examining the Miyagi earthquake.
Students and I struggled with data from a depth sounding survey of the biblical Sea of Galilee. It's gratifying to learn our result .jpg makes a genuine contribution.
Quite by accident I took some nice pictures of Sea Dragons, and another at the Monterey aquarium.
Garry Clarke came visiting with some fabulous pictures of the Donjuk Glacier. I got him started on a picture web site. Enjoy!

This is a quicktime movie that I made linking astronomy to seismology. (13 min, 40Mb)
This is a quicktime movie of people having fun at the last SEP meeting. (8min, 20Mb)
I'm working on presenting pictures of Cecil Green's trips to Arabia.
I enjoyed a small journey with the Crustal Group.
I'm trying to recover a rare seismic data set.
Ever wondered about acoustic daylight imaging? Here is a quick introduction .
This picture explains (fantastic!) the relation between 1-D and 2-D filtering. To filter, you screw the filter onto the data. Convolution in 1-D does convolution in 2-D. Deconvolution in 1-D does deconvolution in 2-D. Likewise for spectral factorization, etc. Makes a great preconditioner for inversion. Rapidly solves [1+Dxx+Dyy]u=v. The entire "Helix" paper (16 pages of .ps) or html.

In my youth, I puttered with earthquake and nuclear explosion data, but then I found reflection seismology was more fun because the theory more often works. Not to say that the earthquake people do not make interesting discoveries. [ link, ]
