I am Robert M. Powell. My degrees are in Zoology and Environmental Science, with a lot of chemistry courses thrown in, which was fortunate because almost all my professional work has involved extremely detailed chemistry, including some chemical reactions in experiments that hadn't been described before. I’m also a consultant, so get in touch if my expertise matches your needs.
I currently teach environmental science courses at three colleges. I had a very long career prior to becoming a professor, with over 40 years of experience. Here are some highlights:
- Two years as a senior technician in a genetics research lab.
- Eleven years at the Oklahoma Geological Survey (OGS) as an Analytical Chemist.
- Eleven years as a Researcher at USEPA's National Risk Management Research Laboratory, Ada, OK.
- Twenty-four years as an environmental consultant via Powell & Associates Science Services.
- Seven years+ (so far) as a professor at three colleges.
My expertise includes aqueous chemistry, ground water geochemistry, contaminant remediation using permeable reactive barriers (PRBs) in the subsurface and other innovative in situ treatment technologies, ground water sampling, site characterization, contaminant transport and fate, including colloidal contaminant transport, analytical chemistry, exploratory data analysis, risk assessment, technical writing and editing, and providing expert witness support for clients on a variety of environmental topics under litigation. One of my fascinations is sorting out complex data using exploratory data analysis software.
At the OGS I analyzed large numbers of environmental samples, including rocks, coal, surface water, ground water, water from deep sea sediments, uranium levels in ore, and so on; I programmed computers to do the calculations.
At EPA, my emphasis was in surface water and subsurface systems including soil, the unsaturated zone above the aquifers, and ground water, including the transport of contaminants adsorbed onto colloidal particles and as chelates. I was involved in the research and development of low-flow rate and passive purging and sampling of groundwater monitoring wells. I also worked on the development and understanding of the geochemical mechanisms, reaction rates, costs and approaches to in situ contaminant remediation using permeable reactive barrier technology, authoring many reports and peer-reviewed papers in the process. Both these methods are now being used worldwide, for which I get nothing because my work was government-funded, LOL.
As a consultant I have had numerous clients from industry, legal teams, Native American tribes, other consultancies, and government, both local and federal. One of my favorite projects was serving as a member of the six-person External Advisory Group for the Hydrogeologic Workplan at the Los Alamos National Laboratory for seven years; I got to go to New Mexico at least twice per year and I love it there, both the scenery and the stupendously good Mexican food.
About three years ago, I was subcontracted to Michigan Technological University for the State of Michigan. Michigan Tech was contracted to develop a worst-case scenario risk assessment for the Mackinac Straits Line 5 pipelines owned by Enbridge, Inc., should they rupture and release large amounts of oil. I worked on the ecosystems part of the risk assessment.
I've authored 40+ publications, book chapters, and encyclopedia articles and lost count of my professional presentations at around 50 or so.

"People coming from Twitter tend to think of the fediverse as a Twitter-replacement for the obvious reasons, and thus use Mastodon (or perhaps micro.blog), but that’s only a fraction of its potential. The question isn’t if the fediverse can replace Twitter, but if protocols can usurp platforms in our life online. With enough momentum the fediverse can be the fabric of the social web, incorporating existing systems like Tumblr and Medium and outright replacing stragglers."

Special Counsel Jack Smith must be chuckling this morning following this development. It turns out someone in 45’s campaign in Wisconsin made recordings of a meeting held two days after the 2020 presidential election. Whoops! What they caught on tape, and what it means, in today’s piece. https://statuskuo.substack.com/p/lordy-there-are-yet-more-tapes?sd=pf

Let College Board know we are NOT okay with silencing these voices. Join me in taking a stand against Gov. DeSantis and others trying to limit our academic freedom: https://www.thepetitionsite.com/takeaction/109/795/945/?TAP=2430&source_id=US109795945

We all admire Amsterdam for having the vision to replace car infrastructure with bike infrastructure. We see the positive uplift in small business activity, and livability. 🙂👍🏿
Now imagine doing that in reverse. Replace relatively safely walkable and bikeable infrastructure with car infrastructure. In fact, put in freeways. Demolish entire thriving wealthy neighborhoods with freeways that don't serve the neighborhood.🙃
That's what we did to Black folk. That's how we destroyed Black wealth.

A 2s to 3 pz transition. Phase evolution is seen from the rotating frame in which the phase of the 2s orbital is held constant.
As you go up in principal quantum number for an orbital of a given type, the orbital gets an extra node. That's why in the 2s orbital you can see an internal node and an inversion of the phase (denoted by the color).

Humpback whales hunt/eat using a technique called “bubble net feeding.” They create walls of bubbles to capture fish in a virtual net before swallowing them up.
The result is absolutely stunning. Their style of eating is literally an art.

McCarthy tapped 11 Republicans as committee chairs who voted to reject the results of the 2020 presidential election.
11 of the 17 new House committee chairmen are election deniers who were willing to overthrow the democratic process to put trump back in office.
Why isn’t this a bigger story?

EXTREMELY RARE footage of the elusive box jellyfish Chirodectes. Larger than a soccer ball, this jelly is a true ocean mystery, and this video is one of the only in existence, filmed off the coast of Papua New Guinea in 2021.

If you’re still posting on Twitter then you’re actively helping a fascist achieve his goal of controlling the information so he can bend it how he wants.

#physics **The power of exponential growth**

Covid was piddling around the world from the late summer of 2019. I got one of the first cases in Jan. 2020, from my brother-in-law who started the Bracebridge cluster. :) It was just a flu then. The article says that other viruses had a physics effect, but covid was under the noise. No philosophers in the media get the concept. The Chinese were just smart enough to type it first, as it blew up.
