In 1922 Alfred Stieglitz made a series of photographs of cloudy skies, calling them Equivalents because they matched an emotion or mood he was feeling.

This is my Equivalent for today.

Beware. Got pulled aside at the airport because my empty #fountainpen triggered security. It looked exactly like a fountain pen on the x-ray but they were terrified by its threat and needed to see it and disassemble it to be sure it was OK. Security incident barely averted. Sheesh

Happy birthday to the only two women with elements named after them on the periodic table: #MarieCurie & #LiseMeitner.

As I do every year, I will once again repeat my proposal that November 7 should be International #WomenInSTEM Day!

#OnThisDay #OTD #PeriodicTable👩‍🔬🗃️📜
The squares for Curium and Meitnerium from periodictable.com, featuring portraits of their respective namesakes, are presented above a caption "Only two women have chemical elements named after them. Both were born on November 7th." (I'm aware that there was some ambiguity surrounding Lise Meitner's birthday, but Ruth Lewin Sime's biography notes that Meitner celebrated the occasion on November 7.)

What is happening at Goddard is absolutely devastating. We are losing history. We are losing an incredible amount of human talent, skill, and knowledge. Rebuilding it will be impossible same for same. Industry can not absorb the people or the equipment. This is undoing space science in the US.

Goddard spacecraft engineer: "I think it just kind of speaks to the atmosphere of the agency and the nation, where people are like, 'Well, laws don't matter for the people at the top anymore.'"
NASA is sinking its flagship science center during the government shutdown — and may be breaking the law in the process, critics say
"There is just a general acknowledgement that a lot of what is happening is illegal…"

the password to the louvre surveillance server was "louvre"

according to the liberation newspaper, documents dating back to a 2014 inspection by the French National Agency for the Security of Computer Systems reported a staggering detail: "the password of the louvre's video surveillance server was simply " louvre. "

Good morning.
I don't know who did this, but I love you.

I regret to inform everyone that my pedantic brain couldn’t let me live until I knew whether or not dodger blue and blue jays blue are the same blue. They are ONE PANTONE NUMBER APART.

I recently learned the vet’s ticketing system takes photos and the front desk enjoys them immensely. Fast forward to text message threads that are just snoots asking for refills.
