I had chance last night to return to organic chemistry. As usual, I found the explanations of the means to identify compounds. This time it’s the nuclear magnetic resonance. I don’t think I had a thorough explanation.\ in Morrison and Boyd, but I could’ve muffed it.

I’ve begun a series of courses toward data science. The one on statistics goes over some material I’ve known, but the definitions of covariance and correlation are new to me as to their mathematical explanation.

 As today is the anniversary of my entry to State College, I reflect on the time I was a happy graduate student at Penn State. The peak comes in the middle years when I ran my own weekly show. I didn't get paid in college radio, but I had control over my income and my time.

Being a graduate teaching assistant combine an income with an enjoyable job and an open opportunity for advancement through learning. I ran my show how I wanted in conjunction with a partnet who complented my mangement.

KIhan Academy has a lecture on precession, and I also figured that the calendar would also move so that the solstices would not gradually be earlier. What I didn't consider were the perihelia and aphelia would moved along wth precession.

 This week I ran across Langrange multipliers. I found explanations in both MITOCW and khan. It reminds me of eigenstuff enough to understand them. I see a parallel with Lagrange multipliers. It even reminds me of engineering physics, at least the second time I took it in grad school.

I just finished a training on six sigma and started one on bookkeeping in LinkedIn. I also took one in differential equations. It starts much differently than when I took the subject at Penn State. It also starts with slope fields, sorely lacking in the previous course.

 In the times when my life did improve, a major obstacle lifted out in 1967, 1980, and 1990. I’d like a time when my life improved from better conditions.

card., which causes me to clean up the clutter.
I began an econometric class, which is really a simplified course in statistics. It goes further than the quantitative business from long ago., and my desperate meeting with Russell Smith in 1978.

I was going through fintech, which has a use for linear algebra. Covariances seem to have a place in a matrix.

I tried yet another video on eigens, and I uncovered another aspect finding them. Linear algebra came up under corporate finance. I’m still working on visualizing it, rather than understanding it abstractly

I had the though that K acts too much like me in extreme. His obsession about his name N and a lack of empathy gave me pause. I also know through the internet that he’s been struggling financially.

I finished the LinkedIn course on the foundation of SAPGUI, and the resemblance to accounting is quite obvious. There is even a connection to Microsoft Excel.

 

I’m back into visualizing eigens. According to Grant Sanderson, understanding linear algebra requires a foundation in linear transformations, linear systems, determinates, and change of basis. My situation when I took the course only confirms it. Certainly the concept of lowering a dimension was missing, not to mention the null space. Perhaps applications of eigens would give an even better picture.

I stumbled upon linear algebra with Grant Sanderson, something I could have used when I took the course. Just the concept of vectors I lacked until I took the fundamentals of physics, after I’d audited chemical engineering courses. 

I had a beginning session in linear algebra for a definition I never had. The idea that a matrix is actually a linear transform of a vector. Where did that originate? I intend to continue the pursuit.

 Eleven Ways to Manage the AP Team

In other words, help the team follow the goals of the organization and their own aspirations. Help the members move and progress. It’s no different than any success, but it’s rare, which is why so many are severely underemployed and fall into the Alopexian Paradox. The passion dims and the workers either stop any hope or find another outlet for their talents.
I’ve yet to find such an organization. All too often, the organizations for which I’ve worked either were short sighted or didn’t even bother to manage. So far, I’ve been in a “family” business that they throw away their workers in a merger or a business in a declining industry more interested in shedding workers than developing them.

My encounter with the various courses took a change today after Wells Fargo blocked my payment for Coursera Plus annual. I figure I spent enough to feast on all the courses I have already paid and downloaded.
I checked my notebook from the mid-1980’s, and I found storied I had written and forgotten during my time as a hostage of Reaganomics. So it’s time to revise my agenda for the summer.
