Didn't get much sleep due to all the tornadic weather last night. I could have done better today—it is what it is as they say.
Day before yesterday we achieved 3 million page views for the year in two months—thank you for your part, and I hope you found the time spent with us worthy.
Be well and goodnight.

A type of quantum logic gate that processes information using qudits—particles capable of existing in four or more quantum states simultaneously—rather than traditional binary qubits. This advancement exponentially expands computational capacity by encoding multiple dimensions of data into a single photon pair.

As I mentioned just a short time back, I have a dear friend in hospice. She is seeing the last of moments.
Here is some of her work:

A year ago I held my dearest friend as he passed on this day. Fifteen years with Chimmi—a little doggie, and it hurts just as much as any human passing. So, today is not a good day. . . I'll get my head together and see you all in the morning.

Machiavellianism is a meticulously defined, subclinical personality trait characterized by a cognitive and behavioral phenotype optimized for strategic deception, interpersonal exploitation, and unyielding self-interest. It functions as a parasitic strategy that operates in direct contrast to prosocial mechanisms of trust, cooperation, and mutual reciprocity.

Cosmology is the scientific study of the origin, evolution, large-scale structures, and eventual fate of the universe as a whole. Its primary goal is to understand the universe in its totality—how it began (most notably through the Big Bang), how it has expanded and developed over billions of years, and the fundamental physical laws that govern its macroscopic behavior.
