Hello Everyone! Sorry it’s been awhile since I last posted; I’ve been trying to get caught up on classes after conference!
This hot topic is just basically to highlight cool engineering things that I am thankful for:
1. Keys.
I know that this seems like such a silly thing to be thankful for, but I remember how grateful I am for it every time I come home and yay! no one’s stolen my things! Or when I go out to my car in the morning to drive to class and yay! my car is still there because no one has stolen it. So, I’ve included a couple of things that you may not know about keys:
- Wooded locks and keys were used in Egypt as early as 4,000 years ago! It is said that Theodore of Samos invented the key in 6th century BC.
- There are double-sided and even four-sided keys, which make it difficult to pick the lock, since there’s multiple sides!
- Some new high-tech car keys, such as for Mercedez-Benz use an encoded infared beam to communicate codes with the car. One of these keys can cost up to 400 USD!
2. Can Openers.
I never realized how much I enjoy can openers, until I wanted a cup of soup for dinner and then realized I did not have a can opener to open it with. I could have given up and had a sandwich for dinner, but I was determined to have some soup. So, I got out a knife and decided to do what they do on those survival shows and I stabbed the can. I expected it to go in and then, presto I’d have soup in my bowl. Oh, no. I ended up spending half an hour trying to get my knife in the can and the soup out! It was a terrible and my roommate ended up buying me a can opener the next day: lesson learned. So, here are some facts about the can opener:
- Tin cans were used to preserve food as early as 1772, but can openers weren’t invented until the 1850s!
- The first can openers looked like a claw.
- The rotating wheel openers – which I am more used to – were first patented in 1870.
3. Windshield Wipers.

Being from the Pacific Northwest, I’m very happy that my car has windshield wipers, so I can see where I am going when it’s raining out! Here are some facts about the windshield wiper:
- It was invented by a woman! Mary Anderson in 1903. It was operated using a lever inside the car.
- The first intermittent wipers are invented by Robert Kearns – which is actually an interesting story! On his wedding night his left eye became completely blind after a champagne cork hit his eye. For him, the constant movement of the wiper blade troubled his vision. So, that got him thinking about creating an intermittent wiper! And eventually made it in 1963.
- Now there are “smart” windshield wipers, which actually sense rain! Cool.
Thank you Engineering!
