2:34 PM | Are the ocean and atmosphere finally cooperating and is El Niño really here? Probably.
El Niño has been playing with my heart for a whole year now*. It’s coming. It’s not coming. It’s gonna be huge. It’s not coming now. The ocean looks like en EL Niño but the atmosphere doesn’t. Y U SO FICKLE THE CHILD? I cut my loses, ran from this atmospheric/ocean phenomena prediction and healed my bruised […]

Do you use a tide chart to find the best time for your Saturday walk, too? I showed you a vortex street on a plate formed by pulling a paint brush through sugary water as an example. Now today I want to show … Continue reading →

12:30 PM | Merchants of Doubt Movie
Do go see the Merchants of Doubt Movie.  Los Angeles and New York March 6 opening, Chicago, San Francisco, and Washington DC the 13th.  More widely starting the 20th of March.  The movie is inspired by the book of the same name, about how it is established industries can sell Doubt even in areas where the science is pretty well established.The movie is not the book, nor does it make the mistake of trying to put the book on screen.  But it does pick up many of the threads, […]

12:19 PM | Confluence of Danube and Morava river
Confluence of Danube and Morava river. Watching the shear flow on Elbe river the other day, I was reminded of another shear flow which I had watched a long time ago. In 2009, J and I went to Bratislava in … Continue reading →

2:38 AM | For Hoff Yeti Crabs Food, Sex, and Birth Determine Living Space At Vents  
Within just a few short centimeters the temperature drops from 350˚C to -1.5˚C (692 to 29.3˚F). At 2.6 kilometers deep in the Antarctic Ocean lies the East Scotia Ridge (ESR) dotted with hydrothermal vents. Here, in this unique spot the world’s coldest ocean is in contact with one of the seafloor’s hottest environments. Life residing at hostile vents […]

12:30 PM | Better thoughts
During my weird week, I also had a couple signs of beauty.  Both from my nieces, and one in the midst of sadness.  If I haven't reminded you before: I've got great nieces!First, from my niece Kristen, whom you've heard from before, an observation about science/scientists: Somehow I was chosen as one of two students who got to share dinner at an excellent Cuban place (which the school paid for) with most of the chemistry professors and the person who gave a presentation to us […]

12:12 PM | Shear flow
Kelvin-Helmholtz instabilities in a shear flow in Elbe river. Last week I talked about how I wanted to use the “Elbe” model in teaching. Here is another idea for an exercise: On the picture below you see Kelvin-Helmholtz instabilities. They might be … Continue reading →

8:57 PM | A weird week
Between people denying that there is a correlation between CO2 and temperature and several other items, last week was just plain weird for me.  A few pieces of, I hope, some more general interest.One is, of course, the reminder that CO2 is indeed correlated with temperature.  And, of course, since that original article is pushing 6 years old, I should make an update.  (Clue: The conclusions won't change much -- 6 years isn't large compared to the 50+ already used.)  But also […]
