Six STEM Tweets
Six tweets that celebrate engineering and all things STEM.
I scroll so you don’t have to.
Hi 👋 new friends! Welcome. If you like this, let me know. And forward to others.
All past issues are online
Let’s get to it…
#1
Nice visualization 👌😊

It always helps to have a different way of looking at things. Perspective helps in understanding - math and everything else.

CPU used on latest versions of western combat aircrafts:
Eurofighter Typhoon - Intel Core i7-4700EQ
F-35 - Intel Core i7-4700EQ
F-22 - Intel Core i7-4700EQ
Saab Gripen - IBM PowerPC 750
Dassault Rafale - IBM PowerPC 750

My first reaction was a little surprise at these hardware choices - all off-the-shelf chips. But then I realized that it makes sense for cost reasons. And they write custom software on hardened OSs on these chips. So it’s a good engineering trade-off.

In 1957, John Conway built a water computer called WINNIE (Water Initiated Numerical Number Integrating Engine)

Imagine the memory leak on this one. You would have to clean it up with an actual mop. 😆

Today marks the 40th anniversary of the very first flight of Space Shuttle Discovery.
📷 The STS-41D astronauts who went to space #OTD in 1984: Michael L. Coats, Charles D. Walker, Steven A. Hawley, Judith A. Resnik, Richard M. Mullane, and Mission Commander Henry Hartsfield.

What an engineering marvel! The first re-usable spacecraft.

In 1969, IBM engineer Forrest Parry had the idea to affix magnetic tape to a plastic card. Every adhesive failed. He went home and his wife was ironing. She suggested he fuse the tape onto the card with the iron. This is how the magstripe card was born.

I love serendipity!

😁
I am just waiting for someone to make a version that includes the Spock variant 😃
This is issue #38 of #SixSTEMTweets
A few fun facts about 38:
sum of the squares of the first three primes (22 + 32 + 52 )
The atomic number of strontium
The 38th parallel north is the pre-Korean War boundary between North Korea and South Korea (goes through today’s DMZ)
(I got a chance to visit the DMZ this summer. A very unique experience.)
The international calling code 38 was formerly assigned to Yugoslavia until its break-up in 1991 (this is the 2nd in a row of discontinued country codes. Last week’s 37 was assigned to East Germany)
We are now in the “offset by 2” months. The 9th month named after 7 and so on.
Shows that naming things has been a challenge since the ancient times… 😁
I love hearing from my subscriber friends.
