Trying to find a PDF of an older paper online. I tried google scholar first, and hit a complete wall. Tried a regular google search, and did not get anything that actually took me to the paper. Switched to Kagi, a newer, freemium search engine. Literally the first hit was *the* PDF I needed.
Search results for "A Physically Motivated Solution of the Alfven Problem", a 1970 paper by Jay Boris. Google's AI gives me a course in plasma physics that starts relevant, but then goes off into another direction.More goolge search results for the same paper. After the AI block, there are many links to related papers, but they only reference the paper I'm trying to find.Kagi search results for the same paper. The first entry is the actual paper as a PDF. The next items are links to government repositories that contain the original report. All of the results are directly relevant and useful.

A trend I've seen in scientific talks this past few months is speakers including an AI-generated diagram only to say, "This is AI, so don't blame ME if it's wrong! Tee-hee!*" Dude. It's YOUR talk. YOU are responsible for its accuracy. Don't offload your laziness to AI. *tee hee added for emphasis.

A Plan to Stop Solar Storms From Sending Us Back to the Stone Age
The plan involves school-bus-size satellites and a whole lot of salt, and it could provide an ionic ‘air bag’ for the Earth.

This is why we need continuity of measurements,overlap and redundancy of measurements across different locations! The answer has real world implications for how we run and train models and understand how storms arrive at Earth from the sun!

Shocking contrast between the solar wind density values observed by IMAP versus ACE- as much as 20 times higher in the new IMAP versus the very old ACE!!! We know ACE is getting old, but holy smokes that's a staggering difference.
NOAA's real time data feed from the ACE spacecraft. Density is shown in the center plot (orange dots) and never gets higher than 20 ions per cubic centimeter.The corresponding data from IMAP. Density (middle frame) reaches as high as 200 ions per cubic centimeter.

ICE murdered Renée Good in broad daylight. Less than 3 weeks later, they killed Alex Pretti, shooting him 10 times. Every day, we watch as people are ripped from their cars, their homes, their lives. We can't allow ourselves to look away from this cruelty. Abolish ICE.

Space weather storm is here! ...EARLY! This is a good sign for mid-latitude aurora. Unfortunately, real time solar wind data is giving erroneous velocity data (a near constant 300 km/s). We'll pay attention to density and magnetic field to see how this unfolds.

This storm is highlighting our lack of capability. Our two spacecraft capable of real-time solar wind monitoring are struggling. ACE's plasma detector is giving clearly WRONG data, while DSCOVR is known to give unreliable values. SWFO, hurry up!
