Issue #75 of the "Six Science Posts" newsletter is on it's way to inboxes everywhere.

This one has some really neat info about element #75 - Rhenium - one of the rarest elements.

Also, a really fun non-standard measurement unit - the Ferris wheel.

Shakespeare had some faulty shelves at the globe theater so he called for a repairman. The repairman said "I'm here to fix the stairs". A confused Shakespeare informed him, "the fault is not with our stairs, but with our shelves"

Today is 5/29 - a reminder to check your 529 plan (college savings plan) or start one if you haven’t yet.

If you are in a state without a state income tax, you have more flexibility in picking a plan

Check the Iowa and Utah plans - many good options.

Best wishes! πŸ‘πŸ½

What’s a good family friendly TV show we can watch for about 30 minutes after dinner?

Some examples that we’ve enjoyed are: Young Sheldon, Abbott Elementary , The Amazing Race, Modern Family

Looking for other suggestions,

Thanks

I have been so impressed by the first successful private mission to the moon - Blue Ghost Mission 1 by Firefly Space - that I put the highlights in a special issue of my newsletter

After canceling meeting of independent advisers, FDA issues 2025-26 flu vaccine recommendations | CNN The US Food and Drug Administration on Thursday issued recommendations for the composition of influenza shots for the upcoming respiratory virus season, but without input from its independent vaccine ...

In case you, like me, are a high-anxiety human who missed this piece of moderately reassuring news:

Despite many broken things, the FDA *did* make a flu shot recommendation for this fall.

Art isn't about what you have, or what you use, art can be made from the simplest materials. Art is about invention, imagination, individuality . . . you don't need expensive tools and materials in order to be creative.

A friend of mine has an Android app that’s been working great for over a year but started erroring last week.

Different Android versions, different hardware platforms, all showing errors over the last few days.

Any other Android devs seeing this?

Any clues? Thanks!
