The answers to the title questions are, No, Yes, and why not.  What I have been doing instead of blogging lately has mostly been AI training as a freelancer for a company called Outlier.AI.  I can't say what we work on or who we work for.  Name a company or other organization known to have an interest in AI research and Outlier has likely provided services for them.  It is interesting and engaging work that pays better than teaching actual human beings.  

If your theory of everything has tensors set equal to scalars then it is wrong. Simply put, a scalar is a single number that is widely recognized. A vector consists of 3-4 numbers arranged in a specific sequence, typically representing coordinates and time. A tensor is an array of these numbers in a 3x3 or 4x4 matrix. There are nuanced details to this; for instance, in certain complex scenarios, a set of numbers can be defined where scalars are represented as pairs of numbers, like complex numbers in the form of a+bi. However, to maintain simplicity, we will not delve into those complexities. To summarize, the initial statement of this post can be rephrased to say that a 4x4 matrix of numbers is not equivalent to a single number.

Robert Zubrin, a great Aerospace Engineer and advocate for human space exploration, has a credible proposal to move the ISS to higher orbits around the Earth under its own power using electric propulsion.  This would not be a fast process, but it would not need to be a fast process since it is a space station, not a spacecraft.   Think of it this way, ISS is to space what an oil platform is to the sea.  People don't realize that many of those aren't anchored to the seabed but float, and interface with equipment placed on the seabed below.   They move slowly, very slowly compared to a motor vessel.  Moving ISS would be like that it would take years.  With enough time even a small thrust can

The northern lights as one would expect and see them if they were in the frozen reaches of Canada, Scandanavia, or Russia, maybe and maybe not.  However, a glow in the sky unlike anything most of us will see in the 48 contiguous United States of America was visible last night, and may be visible again tonight, and Sunday night.  For the first time since 2003 a G5 geomagnetic storm is predicted to hit us.   There have been a series of solar flares emitted in the correct direction and timing for the charged particles released to interact with Earths geomagnetic field.  These particles are either deflected by Earth's magnetic field or directed towards the poles.  The result of this interaction and interaction with our atmosphere is the r

Diversity, Equity, and Inclusion (DEI) have become buzzwords often debated within the United States, sometimes controversially perceived as a redistribution of opportunities. However, in a global context—such as in the Laser Interferometer Space Antenna (LISA) project, led by the European Space Agency and NASA—DEI adopts a unique significance. Here, it is about creating a welcoming and safe environment for all qualified researchers from across the globe.

Avi Loeb he prolific Harvard astrophysicist, dances on the edge of cosmic controversy. His research spans black holes, gamma-ray bursts, and the early universe, but it’s his extraterrestrial musings that have set tongues wagging. What he is right about is if alien intelligences exist one of the most interesting things, they could find would be another technological alien species.  If they exist it makes sense that they would observe us from time to time.  Space is full of a whole lot of nothing alive, then a whole lot of single cell life, and technological complex multi cellular life seems rare.   That would make us interesting.
