It has been a very long time since I posted anything here. Teaching at a local community college is taking up all of my time. I wanted to share this video because this gives a very good visual as well as analytical explanation to both a complicated theorem for signal processing, and also a physical phenomenon whereby you can accurately either determine where a particle is or how fast it's moving, but never both accurately at the same time (e g., where is the speeding bullet, or how fast is that rock moving?). Enjoy!!

The Heisenberg uncertainty principle is just one specific example of a much more general, relatable, non-quantum phenomenon. Apply to work at one of my favor...

It has been a while since I posted anything. Here is a slide generated as an inspiration from part of my microbiology class...Your cells burn and bleach chemicals that cannot get destroyed with enzymes. How do they do it? With oxygen! see below...

The genetics and Immunology classes are proceeding nicely. So let me post a slide about tautomerism from general chemistry. What is the link? tautomerism may stabilize certain base pair mismatches during DNA replication and be one underlying cause of genetic change. They key to understanding tautomerism comes with understanding resonance structures of deprotonated molecules.

You need to register to get access to the full article ( ), but the part that is free (https://www.newscientist.com/article/mg23130870-200-life-evolves-so-easily-that-it-started-not-once-but-many-times/) is an interesting take on evolution. Part of the transitional process of evolution is the development of several possible solutions for "living", and letting mother nature/chance take its course. There is rarely only one solution from the beginning, even if only one exists by the end.

Far from being a miracle that happened just once in 4 billion years, life's beginnings could have been so commonplace that it began many times over

Stay tuned! I have been spending a lot of time preparing for a genetics class. Soon I will present a series of slides to discuss an aspect of statistics that scares students of biology: the chi-squared analysis! Boiled down to a single sentence, it answers the following question using mathematics: "Does this data look good enough?"

okay, the first of MANY genetics slides. The basis of trait inheritance in most animals and plants is understanding that traits are inherited as one element from a mother and one element from a father, and expressed in the adult, or the child, as pairs of each element, one from the mother and one from the father. Predicting the possible combination is done with Punnet Squares. Here we show Punnet squares. Note on one axis, the mother haplotypes, and on the other axis, the father haplotypes.

Here is the second half, the answer to the blue box. If you are lucky, it can help you too! The difference of perfect squares is the subject to this week's presentation.
