Tidy topological machine learning with TDAvec and tdarec by Jason Cory Brunson, Alexsei Luchinsky, Umar Islambekov

Topological data analysis (TDA) is increasingly integrated into machine learning. Introducing two R packages—TDAvec and tdarec—to bridge TDA with the Tidymodels ecosystem, offering efficient persistent homology vectorization and tidy ML pipelines.

Bug reports, feature requests, and code contributions welcome!

Quantum physicist Dominic Walliman breaks down what's different about Microsoft's approach to Quantum Computing.

The jury is still out on this.

"Last month, the [Microsoft] team made waves announcing their first topological quantum chip, the Majorana 1. More quietly, Nokia Bell Labs has been working on their own version of a topological quantum computer, and the company claims it’s demonstrated the key ingredients in 2023. Both efforts represent scientific achievements, but bulletproof evidence of a topological quantum bit is elusive."

#Cosmologists Try a New Way to Measure the Shape of the #Universe
Is the universe flat and infinite, or something more complex? 15 scientists from seven countries known as Compact collaboration has devised a new way of finding #topological clues.
Looking at the cosmic microwave background (CMB), photons from early universe The CMB tells us how the universe looked just 380,000 years after the #BigBang, when light was first able to travel through the cosmos unimpeded.

If they couldn't even be bothered to look up how to pronounce Majorana correctly (MI-yor-ahna)... it's probably a good bet that the rest of the video's not very well researched either.

Okay I found where you can download PDFs of current USGS topographical data. I didn't quite get these zoomed in to exactly the same point, but here's a topo map next to a parcel map. You see how wild this is.
