Six Science Posts #70

Truly smart buildings, scientist logos and more

Six STEM Tweets

Six tweets that celebrate engineering and all things STEM.

I scroll so you don’t have to.

#1 🤯 

I have worked on technologies to make buildings “smart” - I much rather prefer this type of a smart building.

#2 🤯 

The classics never go away, they just get a new life

#3 🤯 

Beautiful rendition of their most impactful work! 🤩 👏 

#4 🤯 

Today’s chatbots are so eager to please, they will hallucinate before admitting that the question doesn’t make sense.

Like all powerful technologies, use LLMs and chatbots responsibly.

#5 🤯 

:(

#6 🤯 

🤣 

I can hold this pose for Planck’s constant number of seconds.

Planck’s constant is 6.62607015×10−34

This is issue #70. Here’s some new ways to think about 70:

  • Languages with vigesimal (base 20) number systems, do not have a specific word for 70: for example, French: soixante-dix, lit. 'sixty-ten'; Danish: halvfjerds, short for halvfjerdsindstyve, 'three and a half score'.

  • The sum of the first 24 squares starting from 1 is 702 = 4900, i.e. a square pyramidal number (a natural number that counts the stacked spheres in a pyramid with a square base)

  • 70 is a palindromic number in bases 9 (779), 13 (5513) and 34 (2234)

  • It is also a Harshad number in bases 6, 8, 9, 10, 11, 13, 14, 15 and 16.

  • Ytterbium, a chemical element with symbol Yb has the atomic number 70

That’s it for this issue.
