The James Webb Space Telescope has taken longer to reach this point than it took to build a great Egyptian pyramid. A pyramid had to be built in at most 20 years to be ready to act as a burial site for a Pharaoh of old Kingdom Egypt. At a time when forty was old age, even for the ruler of a nation who took the throne at about twenty that was the deadline. JSWT has taken longer and in that respect has been a greater challenge and as great of an achievement. Even if one of over one hundred single points of failure in the process from launch to full deployment goes wrong it is an achievement. There are scientists and technicians who are my age now who started work on aspects of JWST as fresh undergraduate students in the early 2000’s.

A couple of weeks ago Derrick Muller of the YouTube Channel Veritasium made a video asserting that the electrical energy in a circuit does not flow through the wires but through the fields. This is true and yet also a misleading misconception. This misconception in his problem arises because it deals with a circuit loop that reaches from the Earth to the Moon and back with a one-meter gap between the wires. He also uses a definition of the light being “on” which seems to be having any minuscule amount of current flow through the bulb. Then he justifies this will completely correct classical, non-relativistic electromagnetic theory.

No one would like confirmation of the Alcubierre warp drive metric being realized in the real world more than me. However, this is a good time to remind the media and public that a publication does not mean confirmation of this or any other result. Publication in a peer reviewed journal simply means that 2-3 outside experts looked at this paper and can find no obvious reason to think it is false. Confirmation would mean an independent team of researchers trying to replicate this effect in their own laboratory. Then publishing their result. Confirmation would preferably this effect being reliably and robustly replicated in numerous independent labs.

NASA will announce its 2021 crop of astronauts which was delayed at least twice due to COVID 19.  There were around 20,000 applicants for this arduous job.  Which is surprising since the requirements while not super common are not super uncommon either.  I tried my luck at being the third astronaut from the tiny village of Bellwood IL. Maybe I still have a shot at getting to pretend to go to Mars in a ground based NASA simulation mission known as CHAPEA.  Without a doubt those who are selected are or will be in very rare air.  (rimshot)   

UPDATE: Here are NASA's New Astronauts.

Big words are scary and express ideas that are not easily understood and are not easy to be logical about. Apparently, the word neurodivergent is woke now. While the woke want to call pedophiles “minor attracted people” and conservatives are outraged by this (for all the wrong reasons). Of course, simple mathematical ideas that one would learn beyond grade school are also woke and therefore bad.

Critical Race Theory like so much science, even social science, can be used for good or evil. Physics invented the atomic bomb which can destroy the world. Physics invented the nuclear power plant which can generate carbon free energy and help to save the environment. Chemistry and biology invented medicines that can save lives as well as bio toxic and chemical warfare which can take them. Somehow “CRT” is what people want to ban in part due to a total misunderstanding of what it is and what it is not. In the end I will show how I use these ideas to be sure I am being fair to the diverse groups of students I teach math and science to.
