This has been the trend for a long time. Physics really lags.

OK. Not sure why this is newsworthy.

Not to mention uprooting one's family is not an easy task and many may just shift careers.

I wrote this song on Saturday, recorded it yesterday and released it to you today in response to the state terror being visited on the city of Minneapolis. It’s dedicated to the people of Minneapolis, our innocent immigrant neighbors and in memory of Alex Pretti and Renee Good.

Sounds like a model that does not have realistic max limits. We have never had 50" of snow in this area in one storm.

Don't know which weather app to believe yet. Accuweather is predicting at 4 inches of snow on Sunday. But the Apple weather app is predicting 15-18 inches!! Not sure I believe that but if true, snowpocalypse 2026 here we come.

Reminds me of the 9/11 video of jet crashing into the Twin Towers taken by a bystander. The bystander’s voice is heard to say β€œOh Sh*t!” But when they showed it on the news the blanked out the audio. Clearly ok to show the instant of mass death but not to broadcast a β€œcurse”.

Preeminent in what? That is the question.

We had to make a dessert with whip cream and the blender broke. No problem I said. I’ll just grab the power drill, bend a hanger wire into the right shape, and we’ll be in business. Four days later we were still cleaning up residual cream splatter.

If I had that much disposable cash I would definitely make a bid.

This work uses only a very small, non-representative subset of supernovaeβ€”some of which are not even spectroscopically confirmed as being Type Ia β€”and crucially relies on an obsolete version of supernova measurements from circa β‰ˆ 2010. The SN community doesn’t give it serious weight.
